During the shock absorber assembly process, processes such as half-rolling, assembly and nut tightening are required. Assembly is to put the sliding column assembly into the shock absorber body and then tighten the nut. There is a shock absorber assembly equipment, such as the Chinese utility model patent with publication number CN216264447U, which discloses an air pipe placement groove, a positioning mechanism, and a power mechanism; the air pipe placement groove is located on a moving platform moving along a first direction, and is used to clamp the air pipe assembly; the positioning mechanism is used to fix the air spring and make the metal head of the air spring in the same line with the first direction; the power mechanism pushes the air pipe placement groove to move toward the positioning mechanism along the first direction, so that the air pipe in the air pipe assembly is inserted into the metal head of the air spring. The device mainly uses a positioning mechanism to fix the shock absorber. The driving structure and positioning block of the positioning mechanism effectively position and clamp the shock absorber body. However, the shock absorber body has a certain length, and due to the presence of the bladder, active displacement will occur between the components. Positioning only through this structure may reduce the stability of positioning and reduce assembly efficiency. Utility Model Content
