An Improved Clamping Device for Butt Welding Machine

Abstract

The invention discloses an improved clamping device of a butt welding machine. The improved clamping device of the butt welding machine comprises a machine frame. A platform is fixed to the machine frame. A bottom plate is fixedly arranged on the platform and connected with a third electrode. A welding head is connected to the machine frame through a first air cylinder. A workpiece is clamped between the bottom plate and the welding head to be welded. The welding head comprises a clamping plate connected with the first air cylinder. The first air cylinder is connected to the rear side of the clamping plate. A rectangular through groove is formed in the rear side of the clamping plate, and a plurality of first electrodes are arranged on the front side of the rectangular through groove. Each first electrode comprises an insulating jacket fixed to the clamping plate, wherein a conductive head is slidably arranged in the insulating jacket and connected with the clamping plate through a first spring body, a first rubber layer is arranged between the conductive head and the first spring body, and a plurality of toothed parts are annularly distributed at the top of the conductive head. A strip-shaped second electrode is further arranged on the front side of the rectangular through groove. By adoption of the improved clamping device of the butt welding machine, the defects of the prior art can be overcome, and the welding quality in the welding process is improved.

Description

technical field [0001] The invention relates to the technical field of welding machines, in particular to an improved butt welding machine clamping device. Background technique [0002] The butt welding machine is a kind of equipment that uses the resistance heat and plastic deformation of the welding part to weld when it passes through a large current. The butt welding machine is suitable for welding thin metal sheets. During the welding process, the welding part will be deformed under the action of high temperature, which will have a negative impact on the accuracy of the welding process, prone to uneven welds, and even the problem of virtual welding. This problem is in the large-area welding process. is particularly evident in . Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an improved butt welding machine clamping device, which can solve the deficiencies of the prior art and improve the welding quality in ...
