Abstract

The invention discloses a lining press fitting device and relates to the technical field of damper accessories. The lining press fitting device comprises a base plate. A V-shaped block and a base arearranged on the base plate. The base is of a hollow cylinder structure. An annular groove is arranged inside the top of the base. A lining locating block matched with the base is arranged in the base.The upper end face and the lower end face of the lining locating block are provided with an upper groove and a lower groove correspondingly. A lifting ring is arranged in the annular groove. The lining press fitting device is suitable for press fitting of a subway damper lining and accurate in locating and can improve the machining efficiency, save work time, relieve the labor intensity and reduce the rejection rate.

Description

technical field [0001] The invention relates to the technical field of shock absorber accessories, in particular to a bushing press-fitting device and a press-fitting method. Background technique [0002] The commonly used automobile shock absorber bushing is composed of rubber bushing and bushing tube. The press-fitting method is to put the bushing assembly into the guide bushing, and press the bushing into the lifting ring through the guide column. The structure of the shock absorber and the subway shock absorber is different. The structure of the subway shock absorber is as follows figure 1 As shown, it includes a suspension ring 9 and a piston rod 17, wherein the piston rod 17 is provided with a dust cover 16 and a dust cover cover 15, so the existing press-fit bushing tooling cannot be used for the press-fitting of the subway shock absorber bushing, that is The existing bushing pressing device cannot press the subway shock absorber bushing into the lifting ring. [00...
