Machine head structure of multifunctional tube-tube full-position automatic TIG welding

Abstract

The invention discloses a machine head structure of a multifunctional tube-tube full-position automatic TIG welding. The structure is used for butt joint and lap joint of the tube-tube full-position automatic TIG welding, the structure comprises a visual monitoring mechanism, a welding gun angle adjusting mechanism and a wire feeding posture adjusting mechanism, wherein the welding gun angle adjusting mechanism is arranged on the left side of the visual monitoring mechanism and the wire feeding posture adjusting mechanism is arranged on the right side of the visual monitoring mechanism, and the welding gun angle adjusting mechanism and the wire feeding posture adjusting mechanism are correspondingly connected with the visual monitoring mechanism; the visual monitoring mechanism comprises an arc rail plate, a connecting rod, an electric cross sliding block, a camera box and a lens protection cover; and the welding gun angle adjusting mechanism comprises a mounting frame, a rotating block, a pointer, the arc rail plate and a welding gun; the wire feeding posture adjusting mechanism comprises a wire feeding nozzle, a cross rail, the connecting rod and the arc rail plate. According tothe structure, the machine head structure of the multifunctional tube-tube full-position automatic TIG welding is suitable for the butt joint and the lap joint (inserting and connecting) of the tube-tube full-position automatic TIG welding are carried out, and the form of a root is not limited; the visual monitoring mechanism can clearly observes the condition of molten drop transition, so that the welding parameters, the welding gun angle and the wire feeding posture can be correspondingly adjusted; the optimized structure good in stability, the adjustment is simple, the design is simple andconvenient, and the tube-tube full-position automatic welding can be well realized.

Description

technical field [0001] The invention relates to the field of structural design of a welding torch head, in particular to a structure of a welding torch head applied to multi-functional pipe-pipe all-position automatic TIG welding. Background technique [0002] Pipe-pipe all-position automatic TIG welding means to keep the pipe horizontal and fixed, and the welding torch head goes around the pipe for welding, realizing single-sided welding and double-sided forming, which has the advantages of high welding efficiency, good welding quality and low cost. And for the working conditions of complex pipe structure and small pipe spacing, manual welding cannot be operated in such a narrow space, the stability of manual welding is poor, and the efficiency is low, but the pipe-pipe all-position automatic TIG welding can solve this problem well. However, there are still deficiencies in the pipe-pipe all-position welding heads at home and abroad: 1. The traditional welding head cannot ad...

And for the working conditions of complex pipe structure and small pipe spacing, manual welding cannot be operated in such a narrow space, the stability of manual welding is poor, and the efficiency is low, but the pipe-pipe all-position automatic TIG welding can solve this problem very well

However, there are still deficiencies in the pipe-pipe all-position welding heads at home and abroad: 1. The traditional welding head cannot adjust the angle of the welding torch at will. Welding requirements for tube-tube lap joints (insert joints); 2. Th
