Self-adaptive height adjustment device for TIG welding gun

Abstract

The invention relates to the technical field of ship welding, and particularly relates to a self-adaptive height adjustment device for a TIG welding gun. The self-adaptive height adjustment device is fixedly installed on a welding tractor, and capable of self-adaptively adjusting a height of the welding gun, thereby ensuring a constant height of the welding gun during a welding process and ensuring welding quality, and then increasing construction efficiency; and moreover, the device is simple to install, convenient to use, capable of being repeatedly used, low in cost, and high in economical efficiency; and during a welding construction process and a process of driving the TIG welding gun to move forwards by the welding tractor, the device is capable of automatically adjusting constant heights of the welding gun and the centre of a welding joint through the mutual cooperation of a slide adjustment mechanism, a height determination mechanism and the TIG welding gun, and capable of ensuring the mutual cooperation of a wire feeding mechanism and the welding gun, thereby guaranteeing welding quality, increasing working efficiency, and lowering a construction cost.

Description

technical field [0001] The invention relates to the technical field of ship welding, in particular to a welding torch height self-adaptive adjustment device for TIG welding of ship hull plate butt welds. Background technique [0002] In the process of hull welding and construction, in order to ensure the welding quality of the butt weld, according to the construction technology, the welding torch moves with the trolley during the TIG welding of the hull plate butt joint. Since the plate is thin, it will be deformed after cutting and blanking, thus As a result, different degrees of warping and deformation occur in the part to be welded in front of the arc during jigsaw welding, resulting in misalignment. At the same time, due to the stress and deformation generated behind the arc, the welding part is warped. It is necessary to continuously adjust the height of the welding torch to adapt. Continuous manual adjustment on the pressure frame tooling, due to the strong arc radiati...

AI Technical Summary

Problems solved by technology

[0003] 1) Due to the warpage and deformation of the plate after cutting and blanking, the front of the part to be welded is warped and misaligned, requiring the operator to continuously adjust the height of the welding torch to adapt, which is time-consuming and laborious, and the operation is inconvenient, and the accuracy of welding operation is difficult to guarantee

[0004] 2) It is difficult to control the consistency of the distance between the torch head and the weld seam during manual operation, resulting in instability of the welding torch height, which affects the stability of welding quality

[0005] 3) During the welding process, the construction personnel need to adjust the height of the welding torch countless times without interruption, and the arc radiation and dust pollution caused by welding will cause certain damage to the body
