Multi-plate splicing welding tooling

Abstract

The invention discloses a multi-plate splicing welding tooling in the field of a welding tooling. The multi-plate splicing welding tooling comprises a base, wherein the base is movably connected with lower transverse plates; upper transverse plates are movably connected onto the base in a way of corresponding to the lower transverse plates; a framework to be welded is arranged between the upper transverse plates and the lower transverse plates; the framework to be welded consists of two C-shaped plates and two end plates; a third air cylinder is arranged on each lower transverse plate; a piston rod extension end of each third air cylinder is provided with an end plate positioning block; each upper transverse plate is provided with a fourth air cylinder; the piston rod extension end of each fourth air cylinder is provided with a locking seat; the lower part of the locking seat is provided with a first positioning groove; each upper transverse plate is provided with a fifth air cylinder; the piston rod extension end of each fifth air cylinder is provided with an outwards folding bent edge positioning block; crossed slide seats are movably connected with the left side and the right side of the upper transverse plates; edge and corner positioning blocks are movably connected onto the crossed slide seats; a compression part is arranged on each edge and corner positioning block. The two parallel and attached C-shaped plates and the two rectangular end plates can be positioned; the welding efficiency and the welding precision can be improved.

Description

technical field [0001] The invention belongs to the field of welding tooling, in particular to a multi-plate assembly welding tooling. Background technique [0002] Welding is a process and connection method that produces interatomic bonding between two workpieces of the same sex or opposite sex by heating, pressure, or both. In the prior art, there is a fixture for metal sheet welding, its patent application number: 201410570764.4; application date: 2014.10.23; its structure includes a base, a left U-shaped pull sleeve, a right U-shaped pull sleeve, a left U U-shaped pull sleeve two and right U-shaped pull sleeve two; the upper side of the middle part of the base is located at the joint of the two thin plate workpieces to be provided with a heat dissipation groove, both sides of the base are provided with guide grooves, and the left U The pull-down tabs of the first U-shaped pull sleeve, the first U-shaped pull sleeve, the second left U-shaped pull sleeve, and the second U...

AI Technical Summary

Problems solved by technology

The tooling fixture can weld two or more metal sheets to form a whole large metal sheet, which can extend the horizontal or vertical length of the metal sheet to meet production requirements; its disadvantage is that the tooling fixture cannot fix both sides The C-shaped metal plate with L-shaped bending edge is even more unable to position the cuboid frame assembled by two side-by-side C-shaped plates and two rectangular end plates, resulting in uneven butt joint gaps during welding. There are problems such as dents and discontinuous weld seams, which reduce welding efficiency and welding accuracy
