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

Description

technical field [0001] The invention belongs to the technical field of welding equipment, and in particular relates to a rotating shaft conductive structure for a rotary welding device. Background technique [0002] As we all know, threaded sleeves are widely used in many fields as fixed connection parts. The processing of existing threaded sleeves is to connect two ends of a sleeve section with two nuts by welding. When using an electric welding machine to weld, the workpiece needs to be grounded. When the workpiece is rotated and welded, how to connect the workpiece to the ground 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 into contact with the workpiece. There are potential safety hazards in the welding process, and welding will occur if the workpiece is manually driven i...
