Welding fixture for elevator underbeams

Abstract

The invention discloses a welding fixture for elevator underbeams. An adjustable supporting positioning seat and a fixed supporting positioning seat are disposed at left and right ends of a welding working table respectively, the adjustable supporting positioning seat and the welding working table are fixed by an adjustable positioning mechanism through the adjustment of the distance between the adjustable supporting positioning seat and the fixed supporting positioning seat, so that the elevator underbeams in different specifications can be welded, uniformity of welding qualities of the elevator underbeams is guaranteed, and production costs of enterprises are reduced. Compared with manual welding fixtures, the welding fixture has the advantages that the fixture is simple in structure, practical and adaptable to welding the elevator underbeams in various lengths and non-standard design, size deviation of products can be reduced, and uniformity of the product qualities can be improved.

Description

【Technical field】 [0001] The invention relates to a welding fixture, in particular to a welding fixture for an elevator lower beam. 【Background technique】 [0002] The lower beam 2 of the elevator comprises a lower beam body 24, a lower beam guide shoe plate 21 positioned at both ends of the bottom of the lower beam body 24, a lower beam end plate 23 connected to the end of the lower beam body 24 and connected to both sides of the lower beam body 24 ends. The lower beam connecting plate 22. Generally, the above-mentioned components are welded and formed by simple manual positioning. Due to the different specifications of the elevator, the corresponding welding position also changes. It is difficult to ensure the consistency of product quality by using the above-mentioned operation method, and it will affect the assembly and use safety of the elevator. . If the elevator lower beam welding tooling fixture is designed correspondingly for each elevator specification, the produ...

Problems solved by technology

Generally, the above-mentioned components are welded and formed by simple manual positioning. Due to the different specifications of the elevator, the corresponding welding position also changes. It is difficult to ensure the consistency of product quality by using the above-mentioned operation method, and it will affect the assembly and use safety of the elevator.

If the elevator lower beam welding tooling fixture is designed for each elevator specification, the production cost will increase and the workshop space will also be occupied
