Abstract

Provided is a truck anti-crawling absorber assembly process. The truck anti-crawling absorber assembly process is achieved based on a truck anti-crawling absorber assembly tool. According to the truck anti-crawling absorber assembly process, a magnetic sheet is used for replacing a traditional screw rod for clamping, an ejection and bodiless method of a central positioning pin is adopted, the problem that a workpiece is difficult to clamp because of the strange shape of the workpiece is solved, clamping time of workers in the process of installing and welding the workpiece is greatly reduced, production efficiency is improved, and assembly accuracy is high.

Description

technical field [0001] The invention relates to an assembly process of a bogie anti-snake shock absorber, which belongs to the technical field of railway vehicle manufacturing processes. Background technique [0002] With the rapid development of my country's railway industry in recent years, more and more new products have emerged. The anti-snake shock absorber model CL242-K bogie is one of them. It is a welded part. Although the workpiece is not large, it is Due to the peculiar shape, it is difficult to achieve the ideal effect in production by using the clamping and positioning method (screw nut clamping method) designed under the traditional thinking. Therefore, the current assembly efficiency of this anti-snaking shock absorber is low, and the assembly accuracy is low. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a bogie anti-snake shock absorber assembly pro...
