Plate spring type welding clamp

Abstract

The invention relates to a plate spring type welding clamp. A joint of a lower jaw conductor and a cable is arranged on a lower insulator of a lower insulator assembly which is not connected with a handle insulator of a handle assembly, and a fracture zone for blocking heat contact conduction is formed between the handle assembly and the lower insulator assembly, thus the plate spring type welding clamp fundamentally solves the problem that a handle of the prior welding clamp scalds hands in continuous welding. The plate spring type welding clamp comprises the handle assembly and the lower insulator assembly, and the technical key points comprise that the lower insulator of the lower insulator assembly, which is provided with the joint of the lower jaw conductor and the cable, is arranged separately and not connected with the handle insulator of the handle assembly, a connection shaft of an upper insulator fixed in the handle assembly is hinged with a supporting frame of the lower insulator fixed in the lower insulator assembly, and the rest parts are separated from and not contacted with each other. The plate spring type welding clamp has a simple structure and reasonable design distribution, and not only can reduce the manufacturing cost and remarkably prolong the service life, but also can really achieve the continuous welding without scalding the hands and improve the working efficiency.

Description

technical field [0001] The invention relates to an arc welding device used for continuous welding of AC and DC, in particular to a method in which the joint of the lower jaw conductor and the cable wire is arranged at the bottom of the lower insulator assembly which is not connected with the handle insulator of the handle assembly. On the insulator, between the handle assembly and the lower insulator assembly, a fracture zone is formed between the handle assembly and the lower insulator assembly to block the contact conduction of heat, and the handle is not hot during continuous welding. Background technique [0002] At present, the clamping force of the electric welding pliers at home and abroad mostly comes from the steel wire cylindrical compression spring of the traditional structure, that is, the upper jaw of the electric welding pliers joystick assembly and the lower insulator connected with the handle insulator of the handle assembly. The lower pliers mouth connected ...

Problems solved by technology

[0004] The object of the present invention is to provide a leaf spring type electric welding tongs, the handle insulator of the handle assembly is not connected to the lower insulator of the lower insulator assembly, and a line is formed between the handle assembly and the lower insulator assembly to block heat contact. The conductive fracture zone fundamentally solves the problem of hot handles caused by the continuous welding of the existing electric welding tongs. Its structure is simple and the design distribution is reasonable, which can not only reduce the manufacturing cost, significantly prolong the service life, but also make the continuous welding not hot. , improve work efficiency
