Plate spring type welding clamp

Abstract

The invention relates to a plate spring type welding clamp using a plate spring to replace the prior steel wire cylindrical compression spring. Because of a unique structure, 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 a handle assembly and a lower insulator assembly, and the technical key points comprise that a lower insulator in the lower insulator assembly is provided with the plate spring, and the plate spring is fixedly connected with a connecting frame and a supporting frame of the lower insulator. The inner wall of an upper insulator of the handle assembly is provided with a spring-uplifting frame provided with a spring-uplifting shaft and a connection shaft, the supporting frame is hinged with the connection shaft, and the other end of the plate spring is interconnected with the spring-uplifting shaft of the spring-uplifting frame of the upper insulator. The original structure of the plate spring type welding clamp not only has reasonable design, and can shorten a conductor of a lower clamp jaw and save the conductor remarkably, but also can reduce the production cost, remarkably prolong the service life, 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 for continuous welding of AC and DC, in particular to a plate spring which replaces the steel wire cylindrical compression spring of the traditional structure to obtain the clamping force of the welding rod and the handle is not hot during continuous welding. Welding clamp. 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 by the cable is used to clamp the electrode by the compression of the compression spring. After a period of use, the clamping force of the electrode will be significantly weakened with the elastic fatigue of the steel wire cylindrical compression spr...
