Problems solved by technology

But for the clamping method, although there are many clamping points of the pneumatic piano clamping mechanism, the clamping force is uneven, especially for relatively thin cylinder welding, which cannot solve the problem of flatness of the weld after welding; In terms of method, the longitudinal seam welding equipment adopts the cantilever structure to support the welding workpiece. Although the deformation of the beam is considered in the structural design, the actual situation cannot solve the deformation of the beam well, which leads to the gradual change of the welding position between the welding torch and the workpiece, and the welding quality Instability and other issues

Abstract

The invention provides a longitudinal joint automatic welding machine which comprises a machine frame (1). A supporting mechanism and an adsorption device for clamping a workpiece are arranged in the machine frame, the adsorption device comprises an adsorption base (2) fixedly arranged at the upper end of the machine frame (1), a vacuum adsorption tube (3) for adsorbing the workpiece is arranged at the top end of the adsorption base (2) in the length direction, the supporting mechanism comprises a lifting device and a supporting portion which is used for supporting the workpeice and arranged at the upper end of the lifting device, the supporting portion is a V-shaped supporting groove (8) with an upward opening, and the V-shaped supporting groove is located below the adsorption base (2) and is arranged in parallel with the adsorption base (2) on a vertical face. A vacuum adsorption method is adopted for clamping the workpiece, so that working efficiency of welding joint clamping and calibration is improved. The V-shaped supporting groove is adopted to serve as a workpiece supporting frame, so that the problem of poor consistency of the welding quality caused by the adoption of cantilever for supporting the workpiece in ordinary welding is solved.

Description

technical field [0001] The invention relates to an automatic longitudinal seam welding machine, in particular to an automatic welding machine applied to butt joint longitudinal seam welding of thin-walled cylindrical bodies. [0002] Background technique [0003] Automatic longitudinal seam welding machine, also known as automatic straight seam welding machine, is a high-quality, efficient, and non-deformable general-purpose automatic welding equipment for butt longitudinal seam welding of thin-walled cylinders, conical cylinders, flat plates or square boxes with one end open. It can be used for high-quality welding of carbon steel, low-alloy steel, stainless steel, aluminum and its alloys, and can choose argon arc welding, gas metal shielded welding, plasma welding, submerged arc welding and other welding power sources to form a set of automatic longitudinal seam welding system. The equipment can be widely used in steel structures, shipyards, automobiles, thin-walled pre...
