Automatic rotating welding device for pipeline

Abstract

The invention relates to an automatic rotating welding device for a pipeline. The device is that a driving wheel is assembled on a driving wheel bracket, wherein the driving wheel is divided into a driving wheel and a driven wheel which are arranged in parallel and mounted on the driving wheel bracket through driving wheel shafts; the driving wheel bracket is mounted on a driving base through a driving sliding plate; the driving sliding plate can horizontally move along the driving base; a welding gun bracket comprises a lifting vertical column which is vertically arranged, and a transverse cantilever which horizontally extends to be above the driving wheel loading an object; the rear end of the transverse cantilever is detachably connected to the lifting vertical column through a lifting guide sleeve; the transverse cantilever can move up and down; the front end of the transverse cantilever is detachably connected with a welding gun fixing frame of the welding gun through a cantilever arm guide sleeve; the welding gun fixing frame can horizontally move along the cantilever; the welding gun can move in a three-dimensional direction, wherein the three-dimensional direction is namely the guide sliding plate direction, the lifting vertical column direction and the cantilever direction; the welding gun in a certain three-dimensional space can be positioned to any point, so that a weld joint of a welded part can be conveniently positioned, and a stable welding working distance from the welding gun to the weld joint can be kept all the time.

Description

Technical field: [0001] The invention relates to an automatic rotary welding device for pipelines, more precisely, relates to an automatic rotary welding device which is easy to operate and has high production efficiency, and belongs to the field of welding technology. technical background: [0002] When welding circular pipes, it is difficult to place the material of the round pipe. The workpiece is placed flat on the ground and needs to be rotated for a short period of welding, or the workpiece is standing on the ground, and the worker needs to rotate around the workpiece during welding, so the accuracy of welding cannot be guaranteed. Guaranteed, welding is more troublesome, easily causes defective products, increases production cost, and work efficiency is not high. Invention content: [0003] The purpose of the present invention is to provide an automatic rotary welding device for pipelines. The driving wheel drives the workpiece to be welded to rotate at a consta...
