Semi-automatic electric arc welding gun and gun head thereof

Abstract

The invention belongs to the technical field of arc welding gun production, and particularly relates to a semi-automatic arc welding gun and a gun head thereof.The semi-automatic arc welding gun comprises a sliding rail, a sliding block, a welding gun and a corrugated pipe, a through groove is formed in the sliding rail, and a wire guide wheel and a rocking wheel are arranged at the two ends of the sliding rail; corrugated pipes are arranged on the two sides of the sliding block, one ends of the corrugated pipes are fixedly connected with the ends of the through grooves, the ends, away from the ends of the through grooves, of the corrugated pipes make contact with the sliding block, the corrugated pipes are filled with non-Newtonian liquid, the number of the corrugated pipes is one or more, and the volumes of the non-Newtonian liquid filled in the corrugated pipes are the same. The corrugated pipe is used for preventing the sliding block from suddenly shaking or moving at a required position; the two sides of the sliding block are wound and fixed with the rocking wheel through a wire guide wheel through a steel wire rope for controlling the sliding block to move; a through hole is formed in the sliding rail, when the welding gun suddenly shakes or moves due to external force, the working stability of the welding gun is improved, and the size is further reduced.

Description

technical field [0001] The invention belongs to the technical field of arc welding torch production, in particular to a semi-automatic arc welding torch and a torch head thereof. Background technique [0002] Semi-automatic arc welding is an arc welding method in which part of the welding process is carried out automatically by mechanical-electrical devices and partly by manual operation. The wire feeding mechanism of the semi-automatic welding machine can automatically send the welding wire into the arc area as the welding wire melts, but the movement of the arc along the joint is completed by the hand-held welding torch, and in the semi-automatic welding, due to the welding process The welding torch is fixed, but in the case of changing workpieces or performing multiple types of welding at the same station, it is often necessary to adjust the height of the welding torch to adapt to different welding positions, and the fixed welding torch cannot meet the above requirements....

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is: the height of the welding torch needs to be adjusted during welding to adapt to different welding positions, but the fixed welding torch cannot meet the above requirements, and the prior art uses a crank and a rack on the side of the guide shaft Driving the slider to move, the semi-automatic arc welding torch needs to be further optimized in terms of space utilization
