[0002] In the field of mechanical processing, especially for workpieces that need accurate processing and positioning, the design of tooling fixtures is crucial. Traditional processing fixtures often have problems such as inaccurate positioning, inconvenient adjustment, and poor adaptability, which limit processing efficiency and accuracy. Especially when machining the side body of components such as top blocks, since the machining surface is not on the normal positioning surface of the workpiece, a special fixture needs to be designed to ensure the stability and accuracy of the machining.

[0003] Most of the existing top block side body processing fixtures adopt a monolithic design, that is, the connection between the fixture and the top block is fixed and not easy to adjust, which leads to poor adaptability of the fixture to different specifications of top blocks. At the same time, due to the limitation of the structure of the fixture, it is often difficult to achieve accurate positioning of the top block in multiple directions, thereby affecting the machining accuracy.

[0004] In addition, the positioning elements in traditional fixtures are mostly fixed on the base by welding or riveting, which not only makes installation cumbersome, but also requires disassembly and reassembly of the entire fixture once the positioning elements are damaged or need to be adjusted, which greatly reduces the flexibility and maintainability of the fixture.
