Welding fixture for rear wall longitudinal beam assembly

Abstract

The invention discloses a welding fixture for a rear wall longitudinal beam assembly, and belongs to the field of machining of the rear wall longitudinal beam assembly. The welding fixture comprises abase, wherein motors are symmetrically arranged on the upper surface of the base, output shafts of the motors are connected with rotating rods, the rotating rods are of U-shaped structures, movable lantern rings are rotationally arranged on the rotating rods, connecting rods are fixed on the movable lantern rings, supporting columns are symmetrically welded to the upper surface of the base, fixing plates are welded to the tops of the sides, close to each other, of the two supporting columns, through holes are formed in the fixing plates, movable rods are movably arranged in the through holes,connecting blocks are welded to the bottom ends of the movable rods, rotating bases are installed at the bottom ends of the connecting blocks, the ends, away from the movable lantern rings, of the connecting rods are connected to the rotating bases, and spring telescopic rods are rotationally mounted on the connecting blocks. The welding fixture is novel in design, ingenious in structure, capableof conveniently clamping the rear wall longitudinal beam, capable of randomly adjusting the angle of the rear wall longitudinal beam while clamping, convenient for operators to weld, high in practicability and worthy of popularization.

Description

technical field [0001] The invention belongs to the technical field of rear wall longitudinal beam assembly processing, and in particular relates to a rear wall longitudinal beam assembly welding fixture. Background technique [0002] There is a rear wall longitudinal beam in the cab of the car, and it needs to be welded during the processing of the rear wall longitudinal beam. During welding, the rear wall longitudinal beam needs to be clamped by a clamp to facilitate welding. However, the existing clamp The structure is simple, it only has a simple clamping effect, and it is fixed, the angle cannot be adjusted, and it is inconvenient to use. Contents of the invention [0003] The object of the present invention is to provide a welding jig for rear wall longitudinal beam assembly, so as to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides the following technical solutions:...
