Abstract

The invention relates to the technical field of electric welding machine ground clamps, and discloses an electric welding machine grounding clamp which comprises a frame body, a clamping hand is movably installed on the side wall of the frame body, a reset torsion spring is fixedly installed on one side of the clamping hand, the clamping hand is movably installed on the frame body through the reset torsion spring, and a negative electrode wire is fixedly installed on one side of the frame body. A pressure generating cavity with an opening in one side is formed in the inner wall of the frame body, a power transmission block is movably installed on one side of the inner wall of the frame body, and a permanent magnet block is fixedly installed on the inner wall of the power transmission block. The permanent magnet block and the electromagnetic coil are installed in the frame body, so that in the working process, the permanent magnet block and the to-be-welded plate are attracted, a channel is formed between the electromagnetic coil and the to-be-welded plate, magnetism generated when the electromagnetic coil is powered on repels the permanent magnet block, negative pressure is generated in the pressure generation cavity, and the electricity transmission block is tightly attached to the to-be-welded object all the time; therefore, the electric arc phenomenon caused by poor contact is avoided, and finally the purpose of increasing the clamping force is achieved.

Description

technical field [0001] The invention relates to the related technical field of electric welding machine ground clips, in particular to an electric welding machine ground clip. Background technique [0002] Electric welding refers to the welding method that uses electric energy to achieve atomic bonding of weldments through heating or pressure. The processing equipment used for electric welding is called electric welding machine. [0003] In the process of using the existing electric welding machine grounding clamp, its main working principle is: the negative electrode of the electric welding machine is connected with the metal grounding clamp, and secondly, the grounding clamp is clamped on the plate to be welded by the action of the spring superior. [0004] However, in the actual use process, the clamping force of the grounding clamp is mainly fixed with the plate to be welded by the action of its spring. When the clamping is loose or the clamping force is insufficient, a...
