Opening Report of Graduation Thesis Design of Mechatronics Major in University 1 Graduation Thesis (Design) Topic: About Toy Modeling Design with PRO/E Software.
1. The source and basis of this topic:
(1) This toy modeling design is based on the current situation and market demand of the toy industry, mainly hoping to master the PRO/E software operation skills imperceptibly through this graduation design, and at the same time cultivate their practical ability in toy design.
(2) The design of the toy motorcycle is mirrored from the front wheel to the rear wheel, and then the main body and shell features of the motorcycle are constructed based on the wheels.
(3) Through the design of motorcycles with PRO/E software, I realized the profoundness of the PRO/E system and got a deeper understanding of the application of its specific commands.
(4) This question comes from Toy Motorcycle Pictorial.
2. The design (research) significance of this topic (current situation and development trend of related technologies):
China has developed from a backward agricultural country to a country in the middle stage of industrialization, while China's toy industry has also developed from a traditional old factory to a world toy manufacturing factory, and has actively moved forward from a world toy manufacturing factory to a creation factory. The constant changes in the toy industry also indicate that the toy industry in China will be more brilliant tomorrow.
China is a big toy producer, but it is not a strong toy producer. Lack of large toy manufacturers, lack of toy development talents and lack of brand effect are the biggest problems. Although China exports a large number of toys (75% of the toys in the world are produced in China), these toys basically enter the international market in the form of OEM. Of the 8,000 toy manufacturers in China, 3,000 have obtained export licenses, but more than 70% of the toys they export are processed with imported materials or samples, that is, they work for foreign brands. Therefore, it is urgent for China toy industry to improve the production technology of China toy industry, take the initiative to occupy the commanding heights of the world toy industry, enhance the core competitiveness of China toy industry and build its own brand of China toys.
With the rapid development of society, people have a higher demand for entertainment after fully meeting the needs of food, clothing, housing and transportation. Of course, toys are indispensable tools for people's entertainment. Therefore, I believe that with the continuous maturity, perfection and standardization of export and domestic market, and the strong support of the state for "creative industries" such as toys, animation and games, the toy industry in China will become stronger and stronger.
3. The basic content, key points and difficulties of this topic, and the means (methods) to be adopted:
(1) Through the comprehensive analysis of the model, it can be considered that the toy motorcycle is composed of front wheel, rear wheel, main body and shell. After the design of toy motorcycle is completed, the color and appearance can be set according to the design, and the model can be rendered when necessary to obtain a more realistic toy model effect.
(2) In toy design, the key and difficult point of design is to create the required surfaces and create the required surfaces from these curves.
(3) Be familiar with the operating skills of PRO/E software and complete the graduation design instructions.

Opening report on graduation thesis design of mechatronics major in university 2 automation and mechanical automation technology
At present, the development of automation technology in China is very fast, and its role in the mechanical field is becoming more and more obvious. The application of automation technology can reduce the labor cost of human beings, and workers can realize the automation operation of large machinery through simple operations, and even complete the work that people can't complete. The development of computer technology provides a guarantee for the application of automation technology in the mechanical field. People have broken their understanding of the traditional machinery industry. Using automatic equipment to realize the call and assembly of machinery not only reduces the labor cost, but also effectively reduces the scrap rate of products, makes the whole mechanical assembly process continuous, greatly shortens the production cycle of products, completes the mechanical assembly task with good quality and quantity, and creates more abundant economic benefits for enterprises.
Application of automation technology in machinery manufacturing
Information automation. Information automation is mainly based on computer technology, including aided manufacturing, aided design, process aided design, database system management and so on. Auxiliary manufacturing refers to the use of numerical control technology to realize the automatic application in the production process of products, and then complete the production of products, also known as numerical control technology; Computer aided design refers to the use of computer design software to complete product creativity, design, modeling, parameter value evaluation and so on. , and realize the accurate measurement of mechanical parts; Process aided design is the link between aided manufacturing and aided design, which can effectively improve the efficiency of process production and optimize it. Product database system management is to realize storage and warehousing by using computing technology, and then realize systematic management of information data.
Automation of material supply and transportation. Material supply and transportation is the transportation and deployment process of raw materials needed for product production. Its automation is to complete the transportation and deployment of materials in an automated way, which is a subdivision of the application of automation in the mechanical field, involving automation equipment, automation devices, automated material transportation, automation software, etc.
Production automation. Production automation can be reflected in mechanical manufacturing and processing, and it can realize automatic loading and unloading of mechanical parts. This automatic loading and unloading can be repeated without system failure, which can effectively reduce labor costs, reduce mistakes caused by human factors, improve product qualification rate and greatly improve product quality.
Equipment assembly automation. Equipment assembly automation is to input the whole assembly process into numerical control equipment, and the computer will complete the mechanical operation, manufacture parts according to specific specifications and shapes, and also complete a series of assembly, debugging, acceptance and other work. It is an automatic production line that can automatically complete mechanical assembly. In the machinery manufacturing industry, equipment plays an important role. Automation equipment can help complete the loading and unloading assembly, so that many tedious manual assemblies can be replaced by machinery, which greatly improves the efficiency of machinery production and is an important part of modern machinery manufacturing.
Detection automation. Automatic assembly parts or equipment need to be inspected, and automatic inspection can accomplish this task well. For new materials, parts and complex products, it is very difficult and inefficient to use manual inspection in machinery manufacturing, which can no longer meet the requirements of current machinery manufacturing and production. It is an inevitable trend that detection automation is applied to mechanical manufacturing. Many detection technologies are used to detect products manufactured by machinery, including current signal, time sequence dislocation, artificial neural network and other more intelligent equipment diagnosis technologies.
Application and development trend of automation technology in machinery manufacturing
Highly integrated. When automation is applied to the field of mechanical manufacturing, the first problem to be solved is to realize the high integration of manufacturing technology. Integration is a production mode, which combines various production contents into an assembly line in a certain order, realizes and completes the automation of mechanical manufacturing on the basis of computer technology, and subdivides it into various subsystems, such as automatic information system, automatic manufacturing system, automatic management system, etc. , cooperate with each other to form a highly integrated mechanical manufacturing automation system.
Smart. Mechanical manufacturing evolved from manual manufacturing, and the traditional simple mechanical manufacturing technology can no longer meet the requirements of the new era. Intelligent system based on advanced computer science can realize the integration, systematization and assembly line of machining, break the limitations of traditional mechanical production, introduce efficient functional system, and combine computer information technology to realize the integration and integration of the system, making it a whole, and strive to realize fully automatic intelligent production. Intelligent manufacturing is to introduce artificial intelligence technology into mechanical manufacturing, and at the same time realize more modern mechanical manufacturing on the basis of automation, so that the technologies between the two can penetrate and blend with each other, analyze and make decisions on mechanical manufacturing with computers, and imitate and replace human work by simulating human thinking. In addition, compared with the wisdom of experts, intelligent machinery manufacturing can self-monitor, find errors in time and make adjustments and improvements. At the same time, it can also preset tasks and constantly adjust its own parameters to get the best state, which is not affected by emotions. It can be seen that intelligent system is higher than artificial intelligence.
Virtualization. Virtualization refers to the use of computer technology, so that mechanical products can be fully simulated in reality, thus improving product quality and work efficiency. For example, the application of computer simulation technology and information control technology in mechanical manufacturing process can better simulate the computer control process, find existing problems and avoid similar mistakes in practical work. Using virtualization can greatly improve the cycle of product design and research and development, ensure product quality, and then enhance the competitiveness in the market.
Concluding remarks
To sum up, the role of automation technology in machinery manufacturing is gradually prominent, which can directly affect the future development of machinery manufacturing in China. It can be seen that it is very important to apply automation technology to form a strong support for machinery manufacturing industry, which can ensure product quality, improve operating efficiency, and then improve the overall efficiency of enterprises, so that machinery manufacturing enterprises can achieve low input and high output, and use automation technology to enhance their market competitiveness and promote their better development.
Opening report on graduation design of mechatronics major in university III. The procurement process of raw materials quality for building electrical engineering is opaque. As the saying goes, a clever woman can't cook without rice. Without qualified raw materials, even the best engineer can't build a safe and reliable house. Similarly, raw materials have far-reaching significance and great influence on the installation of building electrical engineering. This is not only because the quality of raw materials determines whether the results are qualified, but also related to the safety of users' lives and property. At present, the problems of raw materials are manifested in the procurement process, shoddy and unqualified. There is a general phenomenon of kickback in the procurement of raw materials. Driven by the high kickback interest, the procurement staff deceived enterprises to sign procurement contracts with some irregular manufacturers, which made a large number of unqualified products used in the project and affected the quality of the project. On the other hand, there are many fake and shoddy products on the market now. If there is no good difference between enterprises, it is very likely that they will buy unqualified products. All these may have a great impact on electrical engineering.
The process of building electrical construction is shoddy and the management is chaotic. The final result of building electrical engineering needs to be completed through practical operation and finally accepted by users. Undoubtedly, the management order of the construction process, the sense of responsibility and professionalism of personnel all play an important role in the final result. However, there are many problems in the current building electrical construction process, specifically, mainly in the following aspects. First, there is lax construction in line design and laying. This problem is often encountered in the construction process. Butt welding of thick-walled steel pipes will produce internal nodules, which will damage the insulation layer when passing through cables. The fusion welding connection of thin-walled steel pipe will burn through, and when it is buried in concrete, it will penetrate into slurry, which will lead to the blockage of the conduit. These phenomena are not allowed to happen. Second, there is something wrong with the installation of lighting appliances. The model, scale and installation of lighting appliances need special design, but many times engineers don't pay attention to these problems.
Countermeasure analysis of building electrical engineering from the perspective of quality management
Electrical construction personnel should have corresponding sense of responsibility and professionalism. As a professional electrical technician, they should first have a sense of responsibility and excellent professionalism. This requires you to be responsible for your own electrical engineering, make full use of your professional level, and do a good job in the management of technology, quality, visa, progress and safety of electrical engineering. Here, we should pay special attention to the sense of responsibility of construction workers, because the root cause of many accidents in building electrical engineering is not lack of knowledge, but excessive trust in one's own ability or neglect of the work at hand, which eventually leads to accidents. This problem deserves the attention of practitioners in the whole industry. At the same time, professional electrical construction personnel should constantly learn, implement and strengthen new knowledge. At present, the technology of HVDC transmission systems is relatively mature, but there are many kinds of electrical equipment, materials and components. To fully grasp the performance of various electrical products, only by continuous efforts can we accumulate experience and keep up with the times.
Strengthening the quality management of building electrical engineering is an important means to control the construction process and ensure the final result, and it is also the key to improve procedures and improve efficiency. We should start from the whole construction process and run quality management through all construction procedures. First of all, in the construction preparation stage, comprehensive quality control should be carried out. As an electrical technician, we should not only stay at the level of construction according to the drawings, but also be fully familiar with the design drawings, work hard, be good at finding the shortcomings in the drawings, and put forward treatment suggestions in time, which is to safeguard the interests of the owners and improve the technical ability. Secondly, for projects with high engineering requirements and high personnel requirements, it is required to evaluate the construction team and personnel before construction, and adjust the proportion of technicians and general workers. Technical personnel shall undergo training and examination and hold relevant certificates.
Strengthening the safety management of building electrical engineering is always the first, and safety is particularly important for building electrical engineering. Safety here refers not only to the safety in the construction process, but also to the safety in use. To ensure the safety in the construction process, we must first improve the corresponding standardized work measures of the construction personnel, and at the same time, we must also carry out necessary safety training and training, and at the same time emphasize the procedural nature of construction to prevent speeding and speeding. As for the safety of use, higher requirements are put forward for building electrical engineering at a wider level. To ensure the safety of use, first of all, we ask the construction party to ensure the quality and quantity, and work hard on the project, so that there will be no problems. Secondly, users should be trained to use it correctly. Finally, we should do a good job in service measures and communicate and guide users in the process of use.
label
With the continuous development of building electrical technology, the management requirements for building electrical engineering are getting higher and higher. In electrical engineering construction, "quality first, safety first" should be put in the first place. According to the construction characteristics and personnel structure, the whole process from material procurement, construction process to project acceptance is carefully managed, a good quality supervision system is established, people's subjective initiative and creativity are fully mobilized, and the engineering quality of electrical engineering is improved.
