Embodiment Construction

[0018] With reference to accompanying drawing 1 and accompanying drawing 2, the following is further described:

[0019] A welding torch cable self-rotating device is installed between the welding torch tail and the connecting cable. The cable self-rotating device is composed of a rotary body 1, a conductive joint 3 and an elastic conductive ring 2, wherein:

[0020] 1) The upper end of the revolving body is fixed to the cable based on the cable clamp 5 and realizes the conductive connection, and the upper through hole is provided in the axial direction to facilitate the extraction of the upper wire feeding hose 4;

[0021] 2) The upper end face of the conductive joint is in flush contact with the lower end face of the rotary body to form a plane conductive surface 10, the guide joint and the contact part of the rotary body have the same circumferential surface, and the lower end of the conductive joint is fixed to the welding torch 15 of the welding gun and A conductive conne...

Abstract

The welding torch cable self-rotating device set between the welding torch tail and the cable consists of one rotation body, one conducting connector and one elastic conducting ring. The rotation body has upper end fixed to the cable and upper axial hole for leading out the upper wire feeding hose; the conducting connector has the upper face contacting with the lower face of the rotation body, lower end connected electrically to the welding torch and lower axial hole for leading out the lower wire feeding hose; and the elastic conducting ring connected between the rotation body and the conducting connector. The rotation body may be rotated relatively to the elastic conducting ring to avoid cable twisting for normal welding.

Description

technical field [0001] The invention relates to a self-rotating device for welding torch cables, in particular to a self-rotating device for welding torch cables which can prevent the winding of cables during multi-pass automatic welding. technical background [0002] In the prior art, when welding the tube sheet, when the height of the weld seam is relatively high, the multi-pass welding technology is mostly used, but the cable entanglement problem often occurs during the multi-pass welding, which makes the welding torch unable to work. How to ensure the quality of automatic welding, Improving work efficiency and preventing welding torch cable entanglement has always plagued people. SUMMARY OF THE INVENTION [0003] In order to overcome the above-mentioned defects, the present invention provides a self-rotating device for the welding torch cable. On the one hand, the wire can be fed normally, and the cable and the welding torch are always electrically connected; ,Improve...
