Incoming material tensioning mechanism of a circular electric plug spot welding device

Abstract

An incoming material tensioning mechanism of a circular electric plug spot welding device, including a tensioning head for tensioning materials, the tensioning head is connected to one end of a conductive mandrel driven by a stepping motor, and moves along with the conductive mandrel Rotating synchronously, the tensioning head includes a cylindrical outer casing and a fastening core that are nested in each other. Holes are evenly distributed on the side of the outer casing. After the outer casing and the fastening core are sleeved and connected, a The cavity for holding the top tension column, one end of the top tension column and the tension adjustment mechanism on the tension head are installed together, and the tension adjustment mechanism applies different forces to the top tension column, so that the end of the top tension column The top tensioning studs protrude different lengths from the holes on the side of the outer casing to control the tension of the material on the tensioning head. The present invention can tension the incoming material during spot welding and can automatically evenly distribute and rotate the index within 360° of the circumference to facilitate spot welding, and greatly improves the working efficiency of the spot welding device of the circular electric plug.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to an incoming material tensioning mechanism of a spot welding device for a circular electric plug. spot welding device. Background technique [0002] In some circular electric plugs, the peripheral surface of the circular metal shell part on the outer part should be uniformly spot-welded with a circle of strip-shaped metal parts to complete the combination of the two parts, which is a process for the production of finished parts. At present, the production of this process does not have a corresponding ready-made spot welding device, which greatly affects the carrying out of the spot welding process and seriously hinders the production of products. In view of this situation, the inventor provides a spot welding device for circular electric plugs, which can automatically complete the spot welding of two parts, meet the technological requirements of this pro...

Problems solved by technology

[0002] In some circular electric plugs, the peripheral surface of the circular metal shell part on the outer part should be evenly and standardizedly spot-welded with a circle of strip-shaped metal parts to complete the combination of the two parts, which is a process for the production of finished parts. At present, there is no corresponding ready-made spot welding device for the production of this process, which greatly affects the progress of the spot welding process and seriously hinders the production of products

In view of this situation, the inventor provides a spot welding device for circular electric plugs, which can automatically complete the spot welding of two parts, meet the technological requirements of this process, and make up for the current situation that there is no corresponding spot welding device in the existing production process , because in the process of spot welding, the tension degree of the circular metal shell directly affects the effect of spot welding, so in the spot welding device, the tension of the incoming material for spot welding, that is, the circular metal shell is very important. Important, special tensioning mechanism is required to achieve tensioning of incoming materials
