AI Technical Summary
The prior art is difficult to effectively clamp the rear axle shell of different sizes, resulting in a low range of application of the fixture.
A rear axle shell drilling fixture is designed, including a limiting mechanism and a tightening mechanism, and clamping the rear axle shell of any size is achieved through the cooperation of the threaded rod and the slide.
The clamp can effectively clamp the rear axle shell of any size, which improves the scope of application of the clamp, and ensures the stability of clamping through the design of the tightening mechanism.
