Wire side feeding clamping mechanism for welding

Abstract

The invention discloses a wire side feeding clamping mechanism for welding. The wire side feeding clamping mechanism comprises a wire feeding guide pipe, a welding gun clamping body, a cross-shaped sliding device and a wire feeding angle adjusting structure. The wire feeding angle adjusting structure is connected with the wire feeding guide pipe and the cross-shaped sliding device respectively. The cross-shaped sliding device is composed of a single-direction sliding mechanism A and a single-direction sliding mechanism B which are the same in structure. The wire feeding angle adjusting structure is fixed with a sliding table face in the single-direction sliding mechanism B. The wire feeding angle adjusting structure comprises a screw in the middle of a supporting frame, the screw is sleeved with a pressure spring, a T-shaped frame is arranged among the screw, the supporting frame and the wire feeding guide pipe, the two ends of a cross rod of the T-shaped frame are connected with the other end of the supporting frame and the other end of the screw respectively, and the end portion of a vertical rod of the T-shaped frame is connected with the wire feeding guide pipe. Large-angle wire feeding angle adjustment is conducted by adjusting a connecting bolt between the cross rod of the T-shaped frame and the vertical rod of the T-shaped frame, and small-angle fine adjustment is conducted by rotating the screw and adjusting the cross rod of the T-shaped frame up and down by the utilization of the pressure spring.

Description

technical field [0001] The invention relates to a wire feeding system of welding equipment, in particular to a side feeding system for automatic plasma arc welding and tungsten argon arc welding. Background technique [0002] At present, with the continuous development of welding technology, engineering has put forward better requirements for welding quality, and traditional welding methods can no longer meet the needs of modern engineering. Tungsten argon arc welding and plasma arc welding methods can easily obtain high-quality and stable weld quality due to the stable arc length, and the weld surface is beautiful, smooth and uniform, and can be applied to important components such as nuclear power and aerospace industries. In thin plate welding, both gas tungsten arc welding and plasma arc welding do not require filler wire, but in thick plate welding, filler wire is required. The wire feeding system of argon tungsten arc welding and plasma arc welding has no direct relat...

Problems solved by technology

[0004] In view of the above-mentioned prior art, in order to overcome the problems that the general wire feeding holding mechanism tends to have large wire feeding resistance during the welding process, the molten welding wire cannot transition to the molten pool, and the wire feeding angle and position cannot be adjusted in real time during the welding process, the present invention Provide a wire feeding holding mechanism beside the welding, this holding mechanism can easily adjust the wire feeding position and rotating wire feeding angle in two directions, especially during the welding process, the position and angle of the wire feeding can be adjusted at any time without Stop welding when the wire feeding is unstable and adjust the wire feeding position and angle, which improves the welding quality and brings a lot of convenience to the operator
