Abstract

The invention relates to a tool for assembling a yaw damper of a bogie. The tool comprises a base plate seat, wherein the base plate seat is provided with a locating block and a locating support, the locating block corresponds to a base plate groove of the yaw damper, the outer side surface of the locating support is provided with a fixing nut, a lead screw is arranged in the fixing nut, a locating pin is arranged at the front end of the lead screw and is matched with a locating hole of a yaw damper torsion rod, the back end of the lead screw is connected with a handle, the top of the locating support is provided with a limiting groove for limiting the end of the yaw damper torsion rod, and the inner side of the locating support is provided with magnetic sheets for respectively adsorbing the yaw damper torsion rod, a vertical plate and left and right side plates. According to the tool for assembling the yaw damper of the bogie, disclosed by the invention, the magnetic sheets replace the traditional lead screw to clamp the tool, and a jack-out demoulding method of a central locating pin is additionally provided so that a problem that a tool with the abnormal appearance is unlikely to be clamped is smartly solved, the self size and the clamping complexity of the tool are largely reduced, and the manufacturing cost of the tool is saved; and meanwhile, the clamping time of tool assembly by labors is largely shortened and the production efficiency is improved.

Description

technical field [0001] The invention relates to a bogie anti-snaking shock absorber assembly tooling, which belongs to the technical field of railway vehicle manufacturing technology. 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 above-mentioned shortcomings of the prior art, and provide a bogie anti-snake shock absorbe...
