Connecting rod sea automatic loading and welding device used for electric resistance welding

Abstract

A connecting rod seat automatic loading and welding device used for electric resistance welding solves the problems of manual feed and manual penetration into a core shaft which are required during the resistance welding of the connecting rod seat. The device comprises a core shaft penetration mechanism and a connecting rod seat ordering and feeding mechanism, the connecting rod seat ordering and feeding mechanism is positioned on a mounting seat and comprises a connecting rod seat conveying passage, a connecting rod seat conveying air cylinder and a feed limiting plate, the connecting rod seat conveying passage comprises an inclined passage connected with a horizontal passage, the connecting rod seat conveying air cylinder is positioned at the front part of the horizontal passage, a connecting rod seat conveying cylinder rod extends into the horizontal passage from the top down, the feed limiting plate is positioned at the end part of the horizontal passage, and a to-be-weld connecting rod seat conveying position is positioned between the feed limiting plate and the connecting rod seat conveying cylinder rod. According to the invention, the actions of the air cylinder and relevant components are used for replacing the operations of backward manual feeding and manual core shaft penetration, the labor intensity of workers is alleviated greatly while the production efficiency is improved, personnel injuries and accidents are avoided, and the welding quality is enabled to be ensured.

Description

technical field [0001] The invention relates to a feeding device, in particular to an automatic feeding welding device for a connecting rod seat used for welding connecting rods and connecting rod seats on resistance welding equipment. Background technique [0002] During the processing of automotive connecting rod products, the connecting rod and the connecting rod seat need to be welded as a whole. At present, resistance welding equipment is mostly used for welding. Resistance welding is reliable and efficient, and can instantly melt the material between the two electrodes, quickly complete the welding, and meet the welding requirements of connecting rod products. However, the existing resistance welding equipment lacks supporting feeding tooling, and relies on workers to manually operate and feed materials during welding. Insert the shaft into the connecting rod seat, then put the connecting rod seat in place, manually press the connecting rod seat to prevent it from mov...

Problems solved by technology

However, the existing resistance welding equipment lacks supporting feeding tooling, and relies on workers to manually operate and feed materials during welding. Insert the shaft into the connecting rod seat, then put the connecting rod seat in place, manually press the connecting rod seat to prevent it from moving, then press down the upper electrode pressing block, when the connecting rod seat is pressed, the hand leaves instantly, and after welding is completed, the Manually take out the mandrel in the connecting rod seat

This backward operation method has the following disadvantages: 1. When welding, it is necessary to manually insert the anti-deformation mandrel. After long-term use, the temperature of the mandrel is very high, which is easy to burn the hands and cause safety accidents; 2. Due to the cumbersome operation , low efficiency, high labor intensity, soreness in the operator's arm caused by long-term operation; 3. It is easy to crush the hand when welding the connecting rod seat by hand, and there have been many industrial accidents, causing personal injury
