Problems solved by technology

[0004] The straight seam automatic welding machine in the patent CN102233502A has the disadvantage of inaccurate weld centering and manual adjustment, that is, it is necessary to manually adjust the positions of the two base metals on the upper surface of the mandrel during the work process, so that the two base metals The edge to be welded is aligned with the moving path of the welding torch, which reduces welding efficiency and easily leads to accidents

Abstract

The invention aims at providing a straight seam welding machine used for welding a base material. The straight seam welding machine comprises a core shaft and a welding gun assembly. The welding gun assembly is located above the core shaft and can move along the axial direction of the core shaft. The straight seam welding machine further comprises a centering limiting assembly which comprises a centering limiting part, the centering limiting part is arranged to be aligned with a moving path of the welding gun assembly and used for abutting against the to-be-welded edge of the base material, and therefore the to-be-welded edge of the base material is aligned with the moving path of a welding gun. Since the centering limiting part is arranged and is aligned with the moving path of the welding gun assembly, after the base material is placed on the core shaft and the to-be-welded edge abuts against the centering limiting part, the to-be-welded edge can also be aligned with the moving pathof the welding gun, the process of manual aligning by operators is avoided, therefore, welding efficiency is improved, and safety is improved.

Description

technical field [0001] The invention relates to the field of welding, in particular to a straight seam welding machine. Background technique [0002] Straight seam welding machine (Straight seam welding machine) is an automatic welding equipment that realizes the automatic completion of the straight line weld of the welding workpiece through automation and mechanization. Straight seam welding machine is also called straight seam automatic welding machine and longitudinal seam automatic welding machine. It is a kind of automatic welding machine, which can replace labor in large quantities, greatly improve production efficiency and welding quality, reduce labor costs, and improve the working environment of welders. . Such as the corner seam welding of large transformer casings, the straight seam welding of large cylinders, the straight seam welding of solar water heater cylinders, the straight seam welding of steel strips on the production line, the welding of H-shaped steel,...
