Pipeline welding device with welding seam tracking function

Abstract

The invention relates to the field of welding, in particular to a pipeline welding device with a welding seam tracking function. The technical problems that an existing welding seam tracking welding device is not high in welding quality, and gaps in the welding position and excessive upheaval of the welding edge position are likely to be caused are solved. According to the technical scheme, the pipeline welding device with the welding seam tracking function comprises a fixed frame, a placing table and the like; a placing table is fixedly connected to the upper side of the fixing frame. Through the linkage effect of the linkage circular truncated cone and the swing plate, in the back-and-forth moving process of the welding gun, the staying time of the welding gun at the edge position of an annular welding seam is prolonged, and it is guaranteed that the edge position is tightly connected; the contact face of the hinged position of the first clamping plate and the second clamping plate is an inclined face, so that stable transition can be achieved between the first clamping plate and the second clamping plate, and shaking of the moving wheels walking at the hinged position of the first clamping plate and the second clamping plate is reduced.

Description

technical field [0001] The invention relates to the field of welding, in particular to a pipeline welding device with a seam tracking function. Background technique [0002] Existing Chinese patent CN104493335A discloses a kind of welding seam tracking device, and it fixes the welding workpiece on the welding machine frame, and the fast lifting device 1 drops the roller 17 and the welding torch 14 to the surface of the welding workpiece, at this time, the roller 17 and The welding workpiece remains in a contact state. When the surface of the workpiece rises, the workpiece lifts the roller 17 upwards, and at the same time drives the welding torch 14 to move upwards, keeping the welding distance between the welding torch 14 and the welding workpiece unchanged. The moving parts move down with the surface of the workpiece under the action of their own weight, thus ensuring that the roller 17 is always in contact with the welding workpiece; The distance is not equal and welding ...
