Full-automatic replacement electrode head device for welding

Abstract

The invention belongs to the technical field of automobile part production and welding, and provides a full-automatic replacement electrode head device for welding. The full-automatic replacement electrode head device is used for automatically exchanging an electrode head between an upper electrode connecting rod and a lower electrode connecting rod of an electrode holder. The full-automatic replacement electrode head device comprises a secondary rotating assembly, a separating assembly and a taking and placing mechanism, the taking and placing mechanism is arranged on one side of a second-stage rotating assembly, and after the electrode head is separated, the replaced electrode head is placed on the taking and placing mechanism by the aid of a robot, and meanwhile, the robot can automatically pick up a new electrode head from the taking and placing mechanism. The method has the advantages that the abrasion of the electrode connecting rods matched with the conical surface is reduced, the service life of the electrode connecting rods is prolonged, the cost is reduced, and the burden of an operator is relieved; and the device is simple in structure, convenient to maintain and manage,stable and rapid, and can automatically the electrode head.

Problems solved by technology

[0002] When the robot spot welding system is working, due to the wear of the electrode head, the electrode head needs to be replaced. The electrode head on the electrode connecting rod needs to be removed to ensure fast and effective, and to reduce the wear between the electrode connecting rod and the electrode head, and to extend the length of the electrode. The service life of the connecting rod, the existing plan 1: manually use a wrench to unscrew the electrode head, and replace the new electrode head; the existing plan 2: integrate the rotating head into the electrode head mold repairer, the motor rotates, and the rotating mechanism rotates the electrode head Compress and rotate, and the cylinder pulls down the rotating mechanism to separate the electrode head from the electrode connecting rod. The existing method has the following disadvantages: 1. The manual replacement of the electrode head is inefficient and takes a long time, and the upper and lower parallel end faces of the installation are unstable; 2. 、Using the motor in the electrode mold trimmer as power, when the electrode head is rotating, it will rub against the conical surface of the electrode connecting rod, which will cause the conical surface of the electrode connecting rod to wear too quickly, reduce the life of the electrode connecting rod, and make the electrode connecting rod conical Excessive wear of the shaped end causes water leakage or non-vertical phenomenon
