A rotary shaft conductive structure for a rotary welding device

Abstract

The invention discloses a rotating shaft conductive structure for a rotary welding device. The rotating shaft conductive structure is arranged at the rotating shaft of the rotary welding device. The rotating shaft conductive structure includes a rolling bearing, and a conductive rubber sleeve and a conductive copper sheet are arranged on the outer ring of the rolling bearing. The conductive rubber sleeve is sandwiched between the outer ring of the rolling bearing and the conductive copper sheet. The conductive copper sheet is an annular structure composed of upper and lower semicircular arc-shaped sheets. The conductive copper sheet is provided with a conductive joint. On the conductive copper sheet A mounting hole is punched, and a positioning column is installed at the mounting hole. The conductive rubber sleeve includes a tubular material layer, an adhesive layer and a metal mesh layer in sequence from the inside to the outside, and metal powder is distributed in the tubular material layer and the adhesive layer. The scheme ensures the quality of the rotary welding by rationally designing the conductive structure of the rotary welding device, and avoids missing welds and missing welds.

Description

technical field [0001] The invention belongs to the technical field of welding equipment, and particularly relates to a rotating shaft conductive structure for a rotating welding device. Background technique [0002] As is well known, threaded sleeves are widely used as fixed connection components in many fields. In the existing processing of threaded sleeves, two ends of a sleeve section are respectively connected with two nuts by welding. When welding with an electric welding machine, the workpiece needs to be grounded. When the workpiece is welded with a rotary ring seam, how to connect the workpiece to the grounding wire through a wire is a problem that needs to be solved at present. [0003] Welding is called welding and welding. It is a method of joining metals by heating, high temperature or high pressure. Welding requires limbs to drive the welding device to contact the workpiece. There are potential safety hazards during the welding process, and manual driving of th...

Problems solved by technology

Although this method is simple, it is easy to cause damage to the cable winding, and the loss of the cable is very large

Another is to use ordinary grounded rotors, but the grounded rotors are prone to heat and deformation, and with the rotation of the workpiece, the grounded rotors will be stuck after working for a period of time and cannot rotate.

[0005] Therefore, if the method of directly fixing the ground wire on the workpiece for welding is labor-intensive, the work efficiency is low, and the service life of the cable is short.

If an ordinary grounded rotor is used, not only the quality of the product will be affected, but the high temperature will also pose a threat to the safety of production workers
