Welding tool shared by bilaterally symmetrical parts

Abstract

The invention discloses a welding tool shared by bilaterally symmetrical parts. The welding tool comprises a BASE plate, wherein a left angle seat and a front angle seat are mounted on the left side and the front side of the BASE plate correspondingly, a left mounting plate is mounted on the upper side of the left angle seat, a front mounting plate is mounted on the upper side of the front angle seat, positioning pins are arranged on the left side and the right side of the front end of the left mounting plate and in the middle of the front mounting plate, the rear end of the left mounting plate is rotatably connected with a left pressing arm, the right end of the front mounting plate is rotatably connected with a front pressing arm, and the left and right sides of the front end of the left pressing arm and the rear side of the left end of the front pressing arm are connected with reference blocks. When parts are assembled and welded, positioning holes and reference surfaces of the parts and the positioning pins and the reference blocks of the welding tool are assembled in a matched mode, the positioning structures of the bilaterally-symmetrical parts are matched with the structure of the welding tool, the bilaterally-symmetrical parts share one set of welding tool, the production cost is reduced, the structure is simple, and use is convenient and fast.

Description

technical field [0001] The invention relates to the technical field of welding equipment, in particular to a welding equipment shared by left and right symmetrical parts. Background technique [0002] At present, when the projection welding of auto parts needs to replace the welding tool when welding different parts, the same projection welding machine needs to replace the corresponding welding tool when welding different parts. Generally, the welding tool is replaced as a whole. Welding tooling is to ensure the welding size of parts. The traditional welding assembly of parts is a kind of welding parts, corresponding to the development of a welding tooling, the development cost remains high. Patent No. CN210633097U discloses a quick replacement device for welding fixtures. The quick replacement device for welding fixtures is formed by welding the connecting bracket and the lower conductor of the welding fixture. Different from different welded parts, the device only needs t...

Problems solved by technology

[0003] The object of the present invention is to provide a common welding tool for left and right symmetrical parts. By setting a plurality of positioning pins, when fixing the left and right symmetrical parts, the positioning holes of the parts are matched with the corresponding positioning pins. The reference plane of the parts is matched and assembled, and the positioning structure of the left and right symmetrical parts is matched with the structural design of the welding tool, so that the welding of the left and right symmetrical parts shares a set of welding tools, which solves the problem of increased production costs caused by the need to replace the welding bracket in the background technology
