Welding torch cable self-rotator

Abstract

A welding torch cable self-rotating device is installed between the tail of the welding torch and the connecting cable. It is composed of a rotator, a conductive joint and an elastic conductive ring. The upper end of the rotator is fixed on the cable, and an upper conduction hole is provided in the axial direction to facilitate the extraction of the upper wire. Hose; the upper end surface of the conductive joint is in flush contact with the lower end surface of the rotary body, the contact part of the conductive joint and the rotary body has the same circumferential surface, the lower end of the conductive joint is fixed on the welding torch of the welding torch and is electrically connected, and the The through hole is concentric with the lower conduction hole of the central axis, which is convenient for extending into the lower wire feeding hose; the elastic conductive ring is sleeved on the two ends of the rotary body connected with the conductive joint, the rotary body rotates relative to the elastic conductive ring, and the lower end of the rotary body forms a convex Ring, the cable self-rotating device is externally sleeved with the lower end fixed to the welding torch, and the upper end is a bottleneck-shaped insulating sleeve. The upper end of the insulating sleeve is limited to the convex ring, thereby preventing the welding torch cable from being entangled, and ensuring normal welding at the same time, improving welding quality and work efficiency .

Description

technical field [0001] The invention relates to a welding torch cable self-rotating device, in particular to a welding torch cable self-rotating device which can prevent cables from being entangled during multi-channel automatic welding. Background technique [0002] In the prior art, when the tube-to-sheet welding is performed, when the weld seam height requirement is relatively high, multi-pass welding technology is mostly used, but the cable winding problem often occurs during multi-pass welding, which leads to the failure of the welding gun to work. How to ensure the quality of automatic welding, Improving work efficiency and preventing entanglement of welding torch cables have always troubled people. Contents of the invention [0003] In order to overcome the above defects, the present invention provides a welding torch cable self-rotating device, on the one hand, the wire can be fed normally, and the cable and the welding torch are always conductively connected; ,Im...
