Pre-determined point circular seam integrated machine

Abstract

The invention discloses a pre-determined point circular seam integrated machine, comprising a base, wherein a translation frame is arranged on the left side and the right side of the base; a main shaft is arranged in the translation frame; a rotatable clamp and a welding gun module are arranged on the translation frame; the welding gun module is provided with a gun rack connected with the translation frame, a telescopic gun rack, a lifting frame, and a welding gun positioned above the clamp; and the welding guns comprise an argon arc welding gun and a carbon dioxide welding gun. The circular seam welding machine is simple in overall arrangement and reasonable in design, can be used for directly well connecting and welding dispersed end cover and cylinder body once, can cover various processes requiring combination of sealing and welding of a cylinder and an end cover, can meet welding requirements of internal circular seams of multiple types of cylindrical workpieces, is good in welding quality and high in working efficiency, and can effectively overcome defects of manual welding; and by virtue of cooperation of the argon arc welding gun and the carbon dioxide welding gun and an automatic activity design of welding, the welding effect is improved.

Description

Technical field [0001] The invention relates to the technical field of automatic production, in particular to a circumferential seam welding machine. Background technique [0002] Welding equipment is a commonly used equipment in industrial production. The girth seam welding machine generally includes two main parts, a welding part and a rotating part. The rotating part is used to install the workpiece, and the rotating part drives the workpiece to rotate. The workpiece is rotated while welding Part of it is welded. For example, the welding of the inner tank of a water heater and a heat pump requires welding equipment. There are two existing processes, one is to manually spot weld the lid and the barrel together, and then use the ring seam machine. This process requires low efficiency, requires a labor, and the welding quality is also unstable. Another process is to press the two ends of the cylinder body into a certain shape, and then riveting the cover and cylinder body toge...

AI Technical Summary

Problems solved by technology

This process requires low efficiency, requires a manual, and the welding quality is not stable.

Another technique is to press both ends of the barrel into a certain shape, then rivet the cover and barrel together, and then burn the ring seam on the ring sewing machine. The disadvantage of this process is that the life of the inner tank is short, and it is safe during use. question
