The year-end summary of fitter technician's technical work (1)
There are two locksmith classes in the assembly workshop of machinery factory. There are 20 people in the class, male workers 16, accounting for 80% of the class. Mainly responsible for the production and assembly of flue gas turbines, the assembly of industrial pumps and the processing of various accessories. The characteristics of this team are that the staff of the team are United, diligent, careful and positive.
The production of xxxx is characterized by short delivery time and heavy production tasks, and the production pressure of the second-class pliers staff is great. Under the careful organization of the squad leader, with the construction of 5.5 million tons atmospheric and vacuum distillation unit, employees were arranged to work overtime to complete the production tasks, and personnel were organized to carry all the toolboxes of the team members, showing the style of collective unity and harmony.
In daily work, employees leave work early and late, especially in case of emergency work, and do not rest at noon. Voluntary overtime is common. Weekly equipment maintenance is careful and meticulous, leaving no dead ends. Health duty is more thorough than other teams, and the rest room, dynamic balance machine room, workshop glass and factory health area are all clean, which is praised by other teams.
Under the correct leadership of the factory workshop, from 1 June to 1 June, a total of 10 sets of new cigarette machines were assembled and tested (including repair1set), and 4,998 sets of cigarette machine accessories and 7 sets of new cigarette machine rotors were completed. And has made remarkable achievements in team building, and was awarded the "second team" by the branch trade union. Good results have been achieved in team building and production task completion.
This achievement is the crystallization of the joint efforts of xxxx fitter class two employees. In order to achieve the above results, the following work has been done:
First, study hard to improve the overall quality of the team.
Machinery factory is an enterprise that can produce super-large hoods in China, and the domestic market share of hoods and special valves is over 85%. In practical work, we need to constantly update our knowledge and improve our quality. Therefore, our class attaches great importance to learning at work, insists on learning while working, further improves the professional level, deeply understands the characteristics and methods of work, and guides their study and work with correct world outlook, outlook on life and values. Continuously improve the overall quality of the team, seriously study business knowledge, and focus on learning various process skills and knowledge of flue gas turbine assembly. Grasp the key points in learning methods, find the key points in the key points, and combine the knowledge and experience learned in work practice to carry out targeted learning. At the same time, study hard the knowledge related to your job and try to get close to "compound" talents. Learn from teachers around you with an open mind, strive to improve their ability to adapt to their own work needs, learn from each other's strong points, and strive to cultivate employees' work habits of being diligent in thinking, so as to improve their work and thinking ability. In the process of repairing a series of complex tasks such as YL 12000B guide vane group, bearing box, radial bearing, thrust bearing, guide vane assembly and air intake cone in Shengli Oilfield, the whole class brainstormed and worked out the repair scheme together, and finally achieved good results.
Second, work hard and fully cultivate the spirit of love and dedication.
The team has made great progress in ideological realm, professional quality and working ability, which is mainly due to the training and education of workshop leaders and the help and guidance of masters, as well as the good work style and high-spirited mental state of the workshop. These also promote the cultivation of employees' professionalism and love for their posts. "Do what you do, love what you do, specialize in what you do, and refine what you do" is the work style of our class. No matter what work you are responsible for, you can do your best to complete every specific work, thus reflecting the work mentality of loving your post and being dedicated in practical work.
Third, the team attaches importance to the cultivation of employees' professionalism.
Over the past year, the team members have taken care of everyone, taken care of the overall situation, worked hard and forgot to eat or sleep. Make every effort to actively participate in all the work with full enthusiasm and good condition, and strive to complete all the tasks assigned by the workshop. Because of the heavy work, our employees themselves can't say the specific number of accessories, so they can only use "many" to describe it. During the holidays of Spring Festival, May Day and National Day, all our employees don't rest, and they all work overtime on the production line. There are four female employees in our class, who are as excellent as male employees and do not aim at completing tasks. From 65438+ 10 to 165438+ 10, the average monthly working time in our class is 475 hours per person.
Fourth, Qi Xin builds a "five-type" team.
Class two starts with the creation of a "team" and aims at the clear requirements of creating a "five-type team" to cultivate the professional ethics of team employees and guide them to be responsible, patient and enterprising. The team strives to do a good job of "three publicity", that is, the attendance of class members is open, and the attendance of the day is checked monthly; Open working hours, so that everyone can know at a glance how much working hours they earned that month and how much bonus they can get; The amount of tasks is open, according to the post, whoever should do it, regardless of people's behavior, without mercy, and never shows mercy. Successfully passed the basic management of team building and standardized one-star and two-star acceptance. In the fourth quarter, Samsung reached the standard, and Qi Xin worked together to pass the customs smoothly.
Chen xx, an employee, did a good job, and was named "Advanced Individual" in 5438+ 10. Joe xx United employees, regardless of personal gains and losses, and was rated as "advanced individual of the trade union"; In the second quarter, xx was rated as "advanced quality individual"; In the third quarter, Yuan xx and Shen xx were rated as "advanced individuals". Many good people and deeds have emerged in the team. With the joint efforts of all the staff, great changes have taken place in team work, and a road of unity, mutual assistance and harmony has emerged, which reflects the positive attitude of our class members. Shen's father was hospitalized, Teng's mother was hospitalized, and the injured team staff took the initiative to visit. Qu's family was difficult, and the trade union team sent warmth in time, which made him feel the warmth of the team family.
Team members communicate with each other, care for each other, help each other, and feel like a family. In order to create a "learning" team. The team attaches great importance to the training of employees' business skills, and the class has not given up the on-the-job training of employees in the case of very busy production tasks. In order to improve the theoretical level of workers, the whole class of workers jumped into the locksmith skill competition in the branch factory and achieved good results. Chen xx won the second place, Joe xx won the fourth place and Shen xx won the fifth place, which won the honor for the workshop.
In the process of new product assembly, through the joint efforts of technicians in the whole class and workshop, some new products with intellectual property rights, such as YLX2000A nitric acid tail gas turbine, lining slurry pump and 1000 ball valve, were completed, and a QC result was reported. In the course of work, the staff of our class overcame the high temperature and great difficulties, showed the spirit of hard work and dedication, and successfully completed the task. In order to create a "harmonious" team, the Group of Class Two Child Workers cooperated with workshops and factories to organize team members to participate in the "National Fitness Radio Exercise Competition" and the singing competition to celebrate the 80th anniversary of the founding of the People's Republic of China, and won the third prize respectively, showing the spirit of unity and harmony of Class Two children.
Problems and shortcomings of verbs (abbreviation of verb);
Over the past year, Class Two has made some achievements in team building and production tasks, but there are also some shortcomings: the team members do not know enough about API quality management and program documents, and the importance of safety in production needs to be strengthened; Cost accounting needs to be improved. To this end, Class Two will focus on this in 20xx and strive to achieve the following plans:
1, the most economical use principle of consumables; Start with a piece of gauze and a screw, always pay attention to saving electricity and a drop of oil, and implement "double increase and double section"
2. Cooperate with the workshop for production, obey the overall planning and arrangement of the workshop, and do a good job in product quality and employees' own safety.

Year-end summary of fitter technician's technical work (2)
20xx graduated from technical school in March, and was assigned to work in the locksmith group of 16 workshop in the same year. I have worked conscientiously in the position of a locksmith for xx years. Through long-term work practice and uninterrupted study, I have gradually grown into a skilled locksmith, and successfully completed the trial maintenance of various new machines and the manufacture and assembly of various fixtures. It's only 20xx years now? The work in 20xx years is summarized as follows:
First, master the technical theory and application of this type of work.
The fitter operates almost entirely by hand, which requires the skills of workers. Although machine tool processing can complete most processes, some work still needs manual operation, so filing, drilling, scraping and grinding are still the basic skills of fitters.
My filing can reach the flatness of 0.0 15mm (area 50? 100), if the scraping process area can reach 500? 500。
The clearance of fittings can be controlled within 0.015 mm.
The drilling position accuracy can reach 0.05mm, and the tapping accuracy can be controlled at h6. For different materials, it is necessary to polish the front angle and back angle of the tap and select the corresponding lubricating fluid.
The manufacture of fixture is a major feature of fitter in xx workshop. Correctly understanding the design intention and ensuring the shape and position tolerance and technical requirements of the fixture are the basic skills that an excellent locksmith must master, which is my specialty. The assembly of fixture is not a simple building block, it is completed after assembly, and the designer's design intention must be completed. This requires a comprehensive inspection of all parts, whether it has reached the due manufacturing accuracy? Can the function of the fixture be completed after assembly? To this end, I often communicate with designers and craftsmen to understand the design intent, explore solutions to problems, and adjust tolerance repair dimensions. In order to meet the design requirements, products from major workshops are sometimes borrowed for trial assembly until the repair function of the fixture is fully met. The fixture I assembled has hardly been reworked.
It is also my specialty in other precision repairs, and dispatchers habitually come to me to solve such problems.
Second, technical training
I pay special attention to the study of professional theory, and often study the common calculation of mechanical workers, cold working of metal processing, CAD/CAM and manufacturing informatization, fixture design and manufacturing, and even simple mechanical English. Because xxxxxx clamp has original drawings in English, I need to know a little English. I take an active part in all business training in the factory. At ordinary times, I often communicate and even argue with colleagues and technicians, learn from each other and learn from each other's strengths.
Third, the completion of the task.
From 20xx to 20xx, the fixed working time is 65438+more than 8000 hours. Completed more than 2 100 tasks of various fixtures for aircraft engines. Received more than 30 temporary emergency tasks/kloc-0, which ensured the continuous production progress of the factory.
Four, solve production (work) problems, technological innovation, etc.
(1) The self-made fixture saves a batch of turbine locks that are about to be scrapped.
Last year, a batch (600 pieces) of semi-finished hook-and-lock parts were unexpectedly machined with the verticality out of tolerance of 0.05-0. 10mm, and the verticality required by the drawings was less than 0.02 mm According to the inspection of the drawings, they should be scrapped. The technician came to me and asked me if I could solve it. After two days' pondering and testing, I finally designed and manufactured a set of small jigs to correct the verticality of lock pieces, which can adjust the verticality of hook lock pieces to the range of 0.01mm-0.02 mm. Finally, in order to save these locks, five pieces were scrapped, resulting in more than 300,000 economic losses for the workshop.
(2) Clever bolt breaking
Xxxxxxx, which is being repaired in xx workshop, often encounters the problem of bolt fracture during disassembly and assembly. The major workshops entrust our workshop to take it out, and the workshop entrusts me to deal with this kind of problem. I observed that the main cause of bolt fracture was rust death, and the bolt and screw hole were rusted together. When disassembling, strong reverse rotation will break the bolt. When assembling, the bolts will not be tightened according to the specified torque, which will cause the bolts to break due to excessive torque and occasionally due to the use of incorrect tools. The spare parts for the new engine are not available in the factory, so they must be dismantled. The working hours given to me are also calculated by the hour. If you encounter many such problems, you will gradually accumulate some experience.
I often use the following methods to remove corroded bolts.
1, drop kerosene on rusty bolts, nuts, studs, etc. according to the conventional disassembly method. And loosen them after kerosene permeates for a period of time.
2. If the above method still fails, pour rice vinegar (or vinegar essence or aged vinegar) into a container, put it on the fire to boil, then pour it on the rusty bolt with an iron spoon, wait for a moment, and gently tap it with a hammer to take out the rusty bolt, nut or stud.
3. You can also apply dilute hydrochloric acid to rusty bolts, which will be more convenient to disassemble.
The above three methods can take out the severely corroded bolts. After taking out the broken bolts, the damaged hole threads should be trimmed to meet the standards.
For bolts that are not broken due to corrosion, firstly, repeatedly knock, loosen and reset them with a small hammer and a sample punch until they are removed. If it doesn't work, drill it out first and then punch it. You can also use the method of electric spark to knock off the broken bolt and screw on the thread. Breaking bolts is a problem I often encounter, so I write more.
(3) Improve the welding fixture of anodic oxidation fixture.
The welder I did many years ago has a defect, that is, it is not suitable to take out the assembled weldments after welding. Lever it out with a screwdriver. The reason for the analysis is that I only considered the position arrangement of 10 parts, but did not pay attention to welding deformation. Last year, I redesigned and made a set of welding tools, changing the original horizontal design into vertical design, reducing the number of welders' binding members. The advantage of vertical design is that the assembled welded parts can be welded symmetrically on both sides, which reduces the deformation of the fixed frame after welding. After many batches of use, the effect is ideal.
The process of work is a process of integrating theory with practice and constantly improving one's skills. The development of new technology and knowledge is changing with each passing day, and the future work has a long way to go. Only by constantly strengthening business learning can we keep pace with the times. In order to continue to improve personal professional skills.
With the development of society and the innovation of technology, I will pay more attention to the combination of theory and practice in my work, always pay attention to the changes and development of technology and maintenance technology, and make my skills reach a higher level. In the future, I will not only actively participate in technological innovation activities, but also give full play to the role of "mentor". I will advance despite difficulties, work hard, be competent for higher job responsibilities and make my due contribution to the development of the factory.
Year-end summary of fitter technician's technical work (3)
The locomotive workshop of our section is responsible for the rotation of passenger locomotives of Shenyang Railway Bureau, and it needs to provide high-quality maintenance services for on-line locomotives to ensure their normal operation. Therefore, I have to be strict with myself, strictly assemble the pipeline of the locomotive cooling room, so that the cooling system can operate normally, and the accessories I have overhauled will not fail, which will affect the normal operation of the locomotive. There are many kinds of locomotives that we are repairing, and the task is also heavy. Therefore, there are many problems. In practical work, problems are often beyond what we have learned, and there are often some special circumstances. I sum up my experience as follows.
The cooling system is an indispensable part of the locomotive, and the cooling fan of Dongfeng 4B locomotive is driven by hydrostatic transmission technology. This technology can meet the requirements of the change frequency of cold and heat load within the power regulation range of locomotive diesel engine. Hydrostatic motor organically combines the change of cooling fan speed with the change of diesel engine oil and water temperature through the constant temperature element in the temperature control valve. Due to the complexity of hydrostatic system, there are many pipelines and components, and the causes of fan non-rotation or abnormal speed are also complicated. The common faults of hydrostatic system are ultimately reflected in fan non-rotation or abnormal speed. When dealing with the fault, we should accurately judge the cause and take the following steps to check and deal with it.
1. Before starting the machine, check whether the oil level in the hydrostatic oil tank connected to the hydrostatic pump is normal. If opening the transmission dipstick is conducive to oil output, it can be judged that the oil leakage of the hydrostatic pump causes oil channeling, and the normal oil pressure cannot be established in the high-pressure oil circuit, which affects the fan speed: if the oil level is normal, stir the fan by hand, and if the rotation is not flexible, it can be judged that the hydrostatic motor is faulty, and then the hydrostatic pump skeleton oil seal can be replaced or the hydrostatic motor can be overhauled according to the fault phenomenon.
2. Check everything is normal before starting, and then check the engine. When the oil-water temperature reaches a value (water temperature 83? 2. The oil temperature is 65? 2) Under the rotating speed of the diesel engine, manually adjust the screw to make the temperature control valve in a fully closed state (the slide valve is stuck when it cannot be manually adjusted). If the fan speed is normal, it can be judged that the temperature sensing element of the temperature control valve is invalid; If the fan speed is abnormal and there is no obvious temperature difference between the oil return pipe and the oil inlet pipe of the temperature control valve, it can be judged that the gap between the slide valve and the valve body of the temperature control valve is too large or there is strain, and the temperature control valve can be replaced.
3. After judging that the temperature control valve is normal, keep the speed of the diesel engine in the original position, so as to judge the effectiveness of the safety valve or the failure of the hydrostatic pump. In order to reduce the inspection workload, the safety valve can be removed first and tested on the test bench. If the test results do not meet the requirements, the safety valve is invalid and can be replaced; If the test is normal, it is a fault of the hydrostatic motor, and the selected hydraulic motor must be replaced.
4. If the temperature control valve and hydrostatic motor are normal, the diesel engine speed can be kept at the original position. If the fan speed is still low, it can be judged that the outlet pressure of the selected hydraulic pump is not enough, and the normal pressure cannot be established in the high-pressure oil circuit, resulting in the low fan speed. After replacing the hydrostatic pump, the fan speed will return to normal.
5. When checking the hydrostatic pump or motor, measure its volumetric efficiency. Because the clearance between the plunger connecting rod group and the corresponding cylinder is too large, its leakage is bound to be large, so the volumetric efficiency is reduced. When the volumetric efficiency of hydrostatic pump or motor is lower than the specified value, it must be repaired or replaced.
6. After changing the single oil seal of the selected liquid pump and motor to double oil seal, the leakage has been basically eliminated and the fan can be in good operation.
Through the analysis and treatment of hydraulic system faults, I integrated theory with practice, learned a lot of new technical knowledge, exercised my ability to analyze and solve problems, and accumulated good experience for better maintenance of accessories in the future.
Over the past few years, I have taken learning technology and improving my ability as an important joint to improve my overall quality. Take the actual fault handling ability of getting on the bus as the method of accumulating ability, cultivate your own spirit of drilling, and have the determination to solve problems when encountering problems. I believe that only in this way can I make my own contribution to the railway cause. I believe that the leap-forward development of the railway needs more efforts, updating knowledge, making continuous progress and striving to make my own contribution to the railway cause.

Year-end summary of fitter technician's technical work (5)
Summary of technical work of mechanical fitter
A year has passed in a blink of an eye, and we have ushered in a brand-new year. In this year, I adhered to the principle of "obeying the leadership, uniting with comrades, studying hard and working hard", always adhered to high standards and strict requirements, and earnestly completed various tasks. My political literacy, professional level and comprehensive ability have been greatly improved. Now, I will report my thoughts and work in the past year and my future efforts as follows:
Undoubtedly, in the past work, under the leadership of the factory leader and the equipment department, all the employees of the machine maintenance class strictly abide by the various rules and regulations of the factory and strictly demand themselves from all aspects. Always adhere to the actual situation of the factory as the starting point, to ensure the normal operation of the machine as the premise, to minimize maintenance costs and shorten maintenance time as the goal, and constantly learn and summarize work experience and lessons. Although the working environment of mechanics is complicated, every member of the mechanics group is diligent and willing to work, carrying forward the spirit of unity and unity, and constantly improving their professional ethics and professional skills. So as to successfully complete various tasks in a series of challenges and lay a good foundation for each workshop to complete various production tasks on time. With the joint efforts of the leaders and all the machine maintenance personnel, the following outstanding achievements have been made: 1. The repair tasks of the internal water inlet pipe and drainage pipe of the boiler, such as scaling dredging and grate crushing, have been completed. Second, the replacement of the base and impeller of the pickling purification tower and the transformation of the base were completed on time, which made the exhaust system less vibrating and the system more stable. In March and May, 8 bolt machines in Shanghai were successfully cleaned, and some parts were replaced and installed. They were successfully commissioned and put into production in less than two months, which provided a guarantee for the completion of the output task in the future. Fourth, the awareness of safety and environmental protection and the continuous improvement of safety measures, especially through June.
A series of safety activities made every employee aware of the importance of safe production, and the awareness of safety and environmental protection was deeply rooted in the hearts of the people. Of course, there are also some shortcomings in the work process, mainly including: First, the theoretical level of maintenance personnel needs to be improved, especially the mechanical principle, the role of various mechanisms in machinery, tolerance coordination, hydraulic system and material heat treatment. And the related maintenance technology is relatively weak. Second, after heat treatment, the comprehensive mechanical properties such as hardness, plasticity and fatigue strength of the parts can not meet the use requirements, and the shape and position errors of the processed products sometimes need to be reworked or even scrapped because they exceed the limit value of theoretical products, which directly affects the maintenance progress and the performance of the machine, and increases the processing cost and maintenance cost. Third, there are few maintenance personnel, production tasks are biased and the working environment is more complicated. In order to ensure the normal operation of cranes, boilers, water treatment stations, pickling purification towers, various pipelines, etc. 100, coupled with various production tasks, man-made damage to machines and sudden maintenance tasks at night are even more inadequate and labor intensity is greater. Fourth, there is a serious shortage of equipment maintenance, especially the maintenance of vehicles, pipelines and various pumps. One of the main reasons is the shortage of personnel. Five: the assessment of maintenance hours and maintenance costs is not detailed enough. In the future, we will strive to continuously improve and improve through various forms, and strive to continuously reduce maintenance man-hours and maintenance costs, and improve the recycling rate of machine parts. Six: There is no fixed rest place in the workshop. The existing short-sleeved overalls are not conducive to welding oxygen cutting operation.
In the future work, the machine maintenance team will constantly sum up work experience, improve working methods, flexibly use various resources according to the actual situation, and improve work enthusiasm. Combined with the actual development of the factory, overcome all difficulties, strive to ensure the normal operation of the machine, reduce maintenance costs, improve work efficiency, and cultivate a maintenance team that meets the needs of the company's development and has excellent comprehensive quality. We have reason to believe that under the wise decision of the company leaders,
