Welding device

Abstract

The invention discloses a welding device. The welding device comprises a connecting part mounted in a socket, an electric welding machine, a mounting part fixedly mounted on a rear side face of the electric welding machine and a jointing part mounted in the mounting part, wherein a heat discharging window is arranged in the middle of a front end face of the electric welding machine; a positive and negative electrode output opening is formed in the front end face of the electric welding machine below the heat discharging window; an adjusting pivot is arranged on the front end face of the electric welding machine located at the upper right side of the heat discharging window; the jointing part comprises a jointing head and a pinching part fixed at the bottom of the jointing head; a groove part is arranged in the top end face of the jointing head; a triggering device is arranged in the groove part; a first sliding cavity is arranged in the jointing head below the groove part; second sliding cavities are correspondingly formed in left and right sides of the first sliding cavity; a first containing groove is formed in one side, far away from the first sliding cavity, of each second sliding cavity; first pushing blocks are arranged in the second sliding cavities and inclined blocks, which stretch into the first sliding cavity, are arranged at inner sides of the first pushing blocks; locking blocks, which penetrate through the first containing grooves and penetrate through an outer side wall body of the jointing head, are arranged at the outer sides of the first pushing blocks; the first sliding cavity is internally provided with a stud and the bottom of the stud is connected with a motor. The welding device is simple in structure and convenient to use, and can be automatically controlled and locked; the welding device is convenient to insert and the stability is high after the welding device is inserted; a condition that the inserting is loosened due to accidental touch is prevented; meanwhile, the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of welding, in particular to a welding device. Background technique [0002] At present, electric welding machines are used more and more widely, and they rely on plugging and connecting to electricity to work normally. Therefore, whether the electric welding machine is plugged in firmly is the basis for determining whether the electric welding machine can work normally. The setting is long and the weight is heavy, the pick-and-place process is extremely difficult and easily affected by external factors such as dragging and pulling, which makes the plug connection loose and leads to poor contact. And it is exposed to the outside world when it is not plugged in. In the case of people accidentally stepping on or plugging in too much force, it will be bent and damaged, making it impossible to use it normally and shortening the service life. Have requests.
