Spot welding head structure of spot welder

Abstract

A spot welding head structure of a spot welder belongs to the technical field of electric welders and comprises a connector, a spot welding head and a cable. The connector comprises a spot welding head adapter seat and a cable adapter seat, and a first water inlet joint and a first water outlet joint are fixed to one end of the spot welding head adapter seat. The spot welding head is connected with the spot welding head adapter seat by means of threaded fit, and a blind hole is arranged at the center of the spot welding head in the height direction and communicated with a water cooling hole. A cable connector is fixedly arranged at one end of the cable, a cable chuck is fittingly arranged at the other end of the cable and fixedly connected with the cable adapter seat, a spacer bush tube is fittingly arranged outside the cable, a water loop cavity is formed between the inner wall of the spacer bush tube and the cable, one end of the spacer bush tube is fixed to the cable connector, the other end of the spacer bush tube is fixed to the cable chuck, a second water outlet joint is fittingly arranged on the cable connector, a second water inlet joint is fittingly arranged on the cable chuck, and a transition water pipe is connected between the second water inlet joint and the first water outlet joint. The spot welding head structure has the advantage of functioning in extremely cooling the spot welding head and the cable.

Description

Technical field [0001] The present invention is the field of welding machine technology, which involves the point welding head structure of a point welding machine. Background technique [0002] If the industry knows, the point welding machine will heat up the cable due to the cable connected to the cable between the welding machine and the point welding head at the time of work. The cable is aging lightly, and the cable will be burned and even caused by fire.In addition, high temperatures will be generated during the implementation of the welding head to implement the welding process, which will significantly shorten the service life of the point welding head, and can only abandon the old. [0003] The applicant conducted a literature retrieval, but did not see the technical content of effective cooling of the cables and dot weld heads in the published Chinese and foreign patent documents and non -patent documents. For this reason, this applicant has made useful designs.The tech...
