Description

Technical Field

[0002] The rear shock absorber mounting reinforcement plate of a car is a metal die-cast part. After die-casting, mounting holes need to be machined at multiple locations on its surface. Since the rear shock absorber mounting reinforcement plate is an irregular part with mounting holes on multiple sides and the top surface, multiple sets of fixtures need to be designed when machining the mounting holes. Ordinary three-axis machine tools require changing fixtures multiple times to flip and process different surfaces, which results in low processing efficiency, high fixture investment, and serious impact on production cycle. Existing fixtures also have insufficient support, and the workpiece is prone to deformation during machining. Summary of the Invention
