Description

Technical Field

[0001] The utility model relates to the technical field of arc welding machines, in particular to a welding gun clamping device for arc welding machines. Background Art

[0002] AC arc welding machine, also known as arc welding transformer, is a special transformer that converts the AC power of the network voltage into low-voltage AC power suitable for arc welding. It consists of a main transformer and the required adjustment parts and indicating devices. Among AC arc welding machines, the most widely used is the moving iron AC welding machine.

[0003] The utility model with the patent number: CN202020007690.4 discloses a welding tool for automobile fuel pipe, which belongs to the technical field of fuel pipe and cup welding. It includes a fuel pipe clamping mechanism, a cup clamping mechanism and a welding gun, and the fuel pipe clamping mechanism is located at the bottom of the cup clamping mechanism. The utility model uses a cup clamp to perform interference fit with the small port of the cup, and the material is spring steel with good elasticity. By putting the cup into the clamp, the table-shaped structure is squeezed by the cup to generate tension to expand outward to support the cup, preventing the cup from falling. In addition, it has a universal effect for fuel pipe cups of different calibers; in addition, the space formed by the two first fixed plates, the second fixed plate and the third fixed plate clamps the round pipe part of the fuel pipe, and the clamping mechanism driven by the clamping cylinder makes the clamping mechanism clamp the space formed by the protrusion on the third fixed plate and the two first fixed plates and the second fixed plate, so as to achieve the purpose of clamping the fuel pipe and improve the welding quality of the fuel pipe and the cup.

[0004] However, the utility model still has some shortcomings. For example, the device uses spring steel to fix products of different calibers to achieve a universal effect. However, since welding guns of different specifications have different diameters, the pressure that the elastic clamp can apply to welding guns with smaller diameters is smaller and cannot ensure stable fixation. For welding guns with larger diameters, the pressure applied by the elastic clamp when clamping is too large, which may cause damage to the welding gun body. Utility Model Content
