[0002] At present, there are three process methods commonly used in the assembly of automobile shock absorber compression valve assemblies on the market: screw tightening riveting method, direct punching riveting method and rotary riveting method. Among these process methods, the time taken for screw tightening riveting is relatively long, and workers need to use torque wrenches to tighten manually, which is time-consuming and labor-intensive. The punching riveting process has a short riveting time and can be operated with special equipment, but due to structural reasons, it often fails to meet the anti-rotation torque required by the automobile shock absorber compression valve assembly, which easily causes problems such as small compression force value of automobile shock absorber and abnormal noise of shock absorber assembly. The rotary riveting process takes into account the advantages of the above two, which can not only reduce the time taken for riveting compression valve assemblies, but also increase the anti-rotation torque of compression valve assemblies. Because there are many types of shock absorbers in the factory, many types of automobile shock absorber compression valve assemblies are produced, which makes the supporting process equipment very large, resulting in an increase in production costs, which is not conducive to the market competition of enterprises. Therefore, based on the rotary riveting process of automobile shock absorber compression valve assemblies, a universal automobile shock absorber compression valve assembly rotary riveting process equipment is designed.
