Description

Technical Field

[0002] In order to accelerate the attenuation of the vibration of the frame and body and improve the driving smoothness (comfort) of the car, shock absorbers are installed in the suspension system of most cars. Hydraulic shock absorbers are widely used in automobile suspension systems. The principle is that when the frame and the axle make reciprocating relative motion and the piston moves back and forth in the cylinder of the shock absorber, the oil in the shock absorber housing repeatedly flows from the inner cavity through some narrow pores into another inner cavity. At present, shock absorber oil seal pressing equipment is used when assembling shock absorbers.

[0003] The utility model with prior art publication number CN207616046U relates to a novel shock absorber oil seal press-fitting equipment, including a base, a positioning assembly, a press-fitting assembly and an electronic control assembly. The press-fitting is guided by a guide column, which effectively avoids the problems of press-fitting deviation and misalignment, thereby ensuring the quality of the product.

[0004] However, the above device still has the following problems when in use: its shock absorber oil seal press-fitting structure adopts a single structural design, that is, the piston rod accommodating mechanism is driven to descend once, and only a single shock absorber oil seal press-fitting work can be performed. When dealing with batch shock absorber oil seal press-fitting processing work, its shock absorber oil seal press-fitting processing efficiency is general. Utility Model Content
