Lathe fixture refers to the fixture used to process the internal and external revolving surfaces and end faces of workpieces on the lathe. Most lathe fixtures are installed on the spindle; A few are mounted on saddles or beds.

Lathe fixture type

Lathe fixture can be divided into centering type (spindle type), chuck type, chuck type, angle iron type and pattern plate type according to different workpiece positioning methods. ? [ 1]?

1. Centering lathe fixture: On the centering lathe fixture, the workpiece is often positioned with a hole or an excircle, and the fixture adopts a centering clamping mechanism.

2. Angle iron lathe fixture: When machining the rotary end face of the shell, bracket, lever, joint and other parts on the lathe, it is difficult to clamp on the common chuck because of the complex shape of the parts, so it is necessary to design a special fixture. The clamp of this fixture is angle iron, so it is called angle iron lathe fixture.

3. Disc lathe fixture: The fixture of this fixture is specifically called a disc. There are several T-shaped grooves on the disc, and auxiliary elements such as positioning elements, clamping elements and indexing elements are installed, which can process the excircles and inner holes of workpieces with complex shapes. This kind of fixture is asymmetrical, so pay attention to balance.

It's so intuitive. The three-dimensional structure of lathe fixture is decomposed.
