Abstract

A welding device of a piston rod sub-assembly of a telescopic shock absorber is used for welding the piston rod sub-assembly of an automotive telescopic shock absorber. The welding device comprises a piston rod, wherein the upper end of the piston rod is sequentially provided with a dustproof cover and an upper hanging ring; the bottom of the piston rod is provided with a lower positioning seat which is used for supporting the piston rod; and the top of the upper hanging ring is provided with an upper electrode. The welding device is characterized in that a clamping block which is used for fixing the piston rod is arranged between the lower positioning seat and the upper electrode. The welding device of the piston rod sub-assembly of the telescopic shock absorber has the advantages of being simple in structure, enabling the clamping block to be replaced according to the diameter of the piston rod, being short in exchange production time, causing no burn to the surface of the piston rod after welding, improving the product quality and reducing waste products.

Description

technical field [0001] The invention relates to the production of automobile shock absorbers, especially for the welding of piston rod sub-assemblies of automobile cylinder shock absorbers. Background technique [0002] The welding of the cylinder shock absorber piston rod subassembly is a process in the process of the automobile cylinder shock absorber. The quality of this process directly affects the quality of the shock absorber and driving safety. The drop of the lifting ring will directly lead to the adverse consequences of the failure of the shock absorber, and the burn of the piston rod will cause the oil leakage of the shock absorber. Therefore, this process has very strict requirements on the welding of the shock absorber. Whether the surface quality of the piston rod after welding and the welding strength are qualified are directly related to the quality of the shock absorber. Contents of the invention [0003] The invention provides a welding device for a pisto...
