Problems solved by technology

[0003] Welding gun is one of the important parts of arc welding. The current method is to use the welding gun to fix the electrode, and then lower the welding gun when moving the welding gun horizontally during welding. The speed of the welding gun affects the welding solution. The uniformity of the welding gun affects the quality after welding, but it is very difficult for ordinary operators to lower the welding gun at a uniform speed when the staff moves the welding gun horizontally during welding. Therefore, in order to solve the above problems, an arc welding welding gun

Embodiment 1

[0029] refer to Figure 1-4 , a welding gun for arc welding, including a connecting column 9, a circular groove 23 is provided on the outer wall of the bottom of the connecting column 9, and a first installation groove is provided on the inner wall of one side of the circular groove 23, and the top and bottom inner walls of the first installation groove are rotatably connected. With the same screw mandrel 17, the outer wall of the screw mandrel 17 is rotatably connected with a sliding block 15, and the outer wall of the sliding block 15 is slidably connected with the inner wall of the circular groove 23, and the first arc clamp 16 is installed on one side of the outer wall of the bottom of the sliding block 15, and slides Block 15 bottom outer wall is provided with the first sliding groove, and the first sliding groove inwall is slidably connected with the second arc clamp 18, and the second arc clamp 18 side outer wall is equipped with telescopic spring 19, and the telescopic ...

Embodiment 2

[0033] refer to Figure 1-5 , a welding torch for arc welding, also includes an illuminating lamp 22 installed at the bottom of the outer wall on the other side of the connecting column 9 .

[0034] Working principle: Compared with embodiment 1, by providing lighting lamp 22, lighting can be carried out when welding in some dark places, and no external lighting device is needed, which improves work efficiency and facilitates welding for workers.

Abstract

The invention discloses a welding gun for arc welding. The welding gun for arc welding comprises a connecting column, wherein the outer wall of the bottom of the connecting column is provided with a circular groove, the inner wall of one side of the circular groove is provided with a first installation groove, the inner walls of the top and the bottom of the first installation groove are rotationally connected with the same lead screw, the outer wall of the circumference of the lead screw is rotationally connected with a sliding block, the outer wall of the sliding block is slidably connectedwith the inner wall of the circular groove, one side of the outer wall of the bottom of the sliding block is provided with a first arc clamp, and the outer wall of the bottom of the sliding block is provided with a first sliding groove. According to the welding gun for arc welding, through arrangement of the first arc clamp and a second arc clamp, a welding rod is clamped and fixed by moving the second arc clamp through a telescopic spring, the welding rod can be driven to descend by arranging a motor, the lead screw and the sliding block, a worker only needs to move the welding rod when welding, the welding gun is not required to be driven to descend in the moving process, the welding difficulty is reduced, moreover, the uniformity of a solution at the welding position is further improved, and the welding quality is improved.

Description

technical field [0001] The invention relates to the technical field of arc welding, in particular to a welding torch for arc welding. Background technique [0002] Arc welding refers to the use of an arc as a heat source, using the physical phenomenon of air discharge, to convert electrical energy into thermal and mechanical energy required for welding, so as to achieve the purpose of connecting metals. The main methods are electrode arc welding, submerged arc welding, gas shielded welding, etc. It is the most widely used and most important fusion welding method, accounting for more than 60% of the total welding production. Electrode arc welding is the most widely used welding method in industrial production. Its principle is to use the heat generated by arc discharge (commonly known as arc combustion) to melt the electrode and the workpiece and form a weld after condensation to obtain a firm joint. process. [0003] Welding gun is one of the important parts of arc weldi...
