Welding mechanism for rail transit

Abstract

The invention belongs to the technical field of rail transit equipment, and particularly relates to a welding mechanism for rail transit. The welding mechanism for rail transit comprises a base, foursets of supporting columns, a cross beam, a movable base and a welding assembly. The cross beam is fixedly installed on the base through a plurality of sets of supporting columns. The cross beam comprises two sets of cross rods and two sets of sliding rails; the two sets of cross rods are parallel and symmetrically arranged; and the two sets of sliding rails are parallel and symmetrically arranged; Two ends of the movable base are movably clamped to the two sets of sliding rails correspondingly. A clamping assembly is movably mounted on the movable base. The welding assembly is movably clampedonto the movable base, so that the welding assembly can reach any point in a plane projection formed by the sliding rails and the cross beam.

Description

technical field [0001] The invention belongs to the technical field of rail transit equipment, in particular to a rail transit welding mechanism. Background technique [0002] Rail transit refers to a type of vehicle or transportation system in which operating vehicles need to run on specific tracks. The most typical rail transit is a railway system composed of traditional trains and standard railways. High-speed rail trains are a type of rail transit. High-speed rail trains are assembled from four major parts during manufacturing: car body, bogie, upper and lower parts of the car and facilities inside the car. The car body part also includes the head car body, which is the car body with a cab, which is mainly assembled and welded by hand. [0003] In the prior art, the upper cover of the head car is assembled on a welding platform, and the upper cover of the head car is assembled and welded by a plurality of plates. During assembly welding, the operator first splices the...

Problems solved by technology

During assembly welding, the operator first splices the bottom plate of the head car top cover, aligns it visually, and then crouches on the bottom plate of the head car top cover to weld the bottom plate. During the welding process, the operator will Holding a welding torch and a hammer in one hand, knocking the welding slag after welding, and then stepping on the bottom plate of the head car to move to the next welding place. Not only is the work intensive, but it is also easy to make the assembled head The disintegration of the top cover and bottom plate of the car is time-consuming and laborious
