How to design fixtures for machining irregular parts

Fixture refers to process equipment, abbreviated as tooling. According to the characteristics of processed parts, there are two types of fixtures: universal fixtures and specialized fixtures. Universal fixtures can meet the needs of most precision mechanical parts processing. When encountering some irregular parts processing, specialized fixtures are needed.

The purpose of fixtures is to tighten the workpiece during the processing of precision mechanical parts. In a broad sense, any tool that plays a fixed role can be called a fixture. Clamping fixtures are widely used in assembly line operations in electronic factories, and through the auxiliary role of fixtures, production efficiency can be greatly improved.

The fixture is currently moving towards efficiency, versatility, stability, and precision. When processing the fixture, the following points should be noted.

Firstly, it is necessary to consider whether its design and production can meet the accuracy requirements of the precision mechanical parts processing process for the fixture. As long as the accuracy requirements are met, parts that meet the quality requirements can be produced.

Secondly, it is also necessary to consider the operating habits of workers and choose fixtures that meet their working habits, such as requirements for location and loading and unloading space. These factors need to be comprehensively considered in the process of selecting fixtures.

Finally, the selection of materials for the production of fixtures should be appropriate. The finished product should have high strength and stiffness, and be able to adapt to the losses caused by high-strength work. Otherwise, it may be difficult to adapt to high-strength work, which may lead to problems during the operation process and affect the accuracy of precision mechanical parts processing. In addition, the design and manufacturing of fixtures should also be convenient for adjustment and testing.
