Material incoming tensioning mechanism of circular electric plug spot welding device

Abstract

The invention discloses a material incoming tensioning mechanism of a circular electric plug spot welding device. The material incoming tensioning mechanism comprises a tensioning head for tensioningmaterials, and the tensioning head is connected to one end of a conductive mandrel driven to rotate by a stepping motor and rotates synchronously with the conductive mandrel. The tensioning head comprises a cylindrical outer shell body and a fastening core which are sleeved with each other, and holes are uniformly formed in the outer side surface of the outer shell body in the circumferential direction. After the outer shell body and the fastening core are connected in a sleeved mode, cavities for receiving butting columns are formed in the tensioning head. One ends of the butting columns anda tensioning force adjusting mechanism on the tensioning head are installed in a matched mode, and the tensioning force adjusting mechanism applies different force to the butting columns, so that butting column heads on the end portions of the butting columns protrude from the holes on the side surface of an outer shell by different lengths to control the degree of tension of the materials on thetensioning head. The material incoming tensioning mechanism of the circular electric plug spot welding device tension the incoming materials during spot welding and can automatically distribute the rotary indexing within 360 degrees in the circumference to facilitate the spot welding, so that the working efficiency of the circular electric plug spot welding device is greatly improved.

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
