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.
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

Abstract

The invention discloses a method for preparing a rotating conductive mechanism. The conductive mechanism is composed of a rolling bearing and a conductive rubber sleeve arranged on the outer ring of the rolling bearing, including the following steps: a step of preparing a conductive rubber sleeve and a step of preparing a rolling bearing. The specific analysis is as follows: The conductive mechanism is divided into two parts, the rolling bearing connected to the rotating shaft and the conductive rubber sleeve set on the rolling bearing, so that during the welding process, the rotating shaft is connected to the ground plate through the conductive mechanism. The conductive structure of the device improves the safety of the welding process, and at the same time ensures the quality of the rotary welding and avoids missing welds.

Description

technical field [0001] The invention belongs to the technical field of rotary welding, and in particular relates to a preparation method of a rotary conductive mechanism. 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. 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 the workpiece and the weldi...
