Welding method for car bottom of elevator based on welding robot

Abstract

The invention discloses a welding method for a car bottom of an elevator based on a welding robot, wherein the welding robot is applied in the field of welding the car bottom of the elevator. The welding method specifically comprises the following steps that: one surface of a lower car bottom workpiece fixed on a lower car bottom welding fixture is welded at a first welding station; deflection overturning is carried out on the lower car bottom welding fixture; the other surface of the lower car bottom workpiece is welded; and an upper car bottom workpiece is welded at a second welding station. According to the welding method for the car bottom of the elevator based on the welding robot, the upper car bottom workpiece and the lower car bottom workpiece are respectively clamped on an upper car bottom welding fixture and the lower car bottom welding fixture and are welded by adopting the welding robot through the two welding stations, thereby improving the welding efficiency; the welding method is high in intelligence degree, so that the workpieces in various dimensions can be processed by the specially-used welding fixtures, thereby ensuring the welding quality of a product.

Description

technical field [0001] The invention relates to the application field of a welding robot, in particular to an elevator car bottom welding method based on a welding robot. Background technique [0002] The car is a box-shaped space used by the elevator to carry and transport people and materials. The car is generally composed of main components such as the car floor, car wall, car roof, and car door. The elevator car bottom includes an upper car bottom and a lower car bottom. The upper car bottom is a reinforced steel plate welded as a whole, and the lower car bottom is a Tian-shaped or Japanese-shaped metal frame that needs to be welded on both sides. There is a shock-absorbing rubber pad between the lower car bottom, which constitutes the load-bearing layer of the elevator car as a whole. Existing elevator car bottoms generally adopt manual welding with welding fixtures. The welding efficiency is low, welding positioning is difficult to control, and welding deformation is...

AI Technical Summary

Problems solved by technology

Existing elevator car bottoms are generally welded by hand with welding fixtures. The welding efficiency is low, the welding positioning is difficult to control, and welding deformation is easy to occur, which affects product quality.
