A positioning device for assembly of side bearings on railway wagons

Abstract

The invention relates to a location device for upper side bearing assembly for a railway wagon. The location device is characterized by comprising a seat body and a location cover plate arranged at the top of the seat body, wherein the top surface of the location cover plate is a location working surface used for locating the lower plane of an upper side bearing; a height adjustment mechanism is arranged in the seat body; and the top surface of the height adjustment mechanism is bonded with the bottom surface of the location cover plate. Because the height adjustment mechanism is arranged between the seat body and the location cover plate, the location device disclosed by the invention is adaptive to distance changes between the lower planes of upper side bearings and the lower planes of upper centre plates of different automobile types, thus the problem of the need of transforming a fixture with regard to different automobile types is solved, and improvement for the production efficiency is benefited.

Description

technical field [0001] The invention relates to a positioning device, in particular to a positioning device for assembling side bearings on railway wagons. Background technique [0002] In the car body manufacturing process of railway wagons, the position of the upper center plate and the position and size of the upper side bearing are important quality control points, especially the height of the lower plane of the upper center plate and the lower plane of the upper side bearing is particularly important, which directly affects The driving safety of the vehicle is the key quality control point in the manufacturing process of the truck body. In the existing assembly process, the lower plane of the assembled upper center plate is generally used as a reference, and after positioning the lower plane of the upper side bearing and the position of the car body on the side bearing assembly tool, the upper side support body and the car body are welded together. Body joint welds. H...

Problems solved by technology

However, since the distance between the lower plane of the upper center plate and the lower plane of the upper side bearing of each vehicle is different, the fixed upper side bearing positioning device cannot be adjusted conveniently, and the positioning tooling needs to be rebuilt. However, the modification of tooling is time-consuming, laborious, and inefficient, which often affects the progress of car body manufacturing and modification production.

At present, there is no better assembly tool that can be adjusted easily
