Rapid automatic pipeline welding machine

Abstract

The invention provides a rapid automatic pipeline welding machine. The rapid automatic pipeline welding machine comprises a cross beam and clamping and fixing assemblies arranged at the two ends of the cross beam; a screw and nut pair is arranged on the lower surface of the cross beam in the axial direction, a nut is connected with a spraying gun clamping part which is arranged vertically and downwards, each clamping and fixing assembly comprises a motor fixing base and a clamping sleeve, horizontal rotating shafts are arranged in the motor fixing bases, the surfaces of the rotating shafts aresleeved with first gears, the rotating shafts are driven by motors arranged outside the motor fixing bases, each clamping sleeve is composed of an upper half arc pipe and a lower half arc pipe whichform a round pipe, the outer surfaces of each upper half arc pipe and the corresponding lower half arc pipe are provided with racks matched with the first gears, the racks on the outer surfaces of theupper half arc pipes and the lower half arc pipes are arranged along the circumference of the round pipes formed by the upper half arc pipes and the lower half arc pipes. According to the welding machine, due to arrangement of an air cylinder and a propelling assembly, the machine adapts to welding of pipelines with any pipe diameters.

Description

technical field [0001] The invention belongs to the field of welding equipment, in particular to a fast automatic welding machine for pipelines. Background technique [0002] Steel structures have the characteristics of light weight and high strength, and have been widely used in various modern buildings, including large stadiums, public buildings, long-span factory buildings, municipal public works, etc. In the process of laying steel structure pipelines, the welding of pipe joints is the top priority. At present, most of the pipeline welding adopts manual welding. Manual welding is not only time-consuming and laborious, but also prone to low welding accuracy and pipeline failure. Problems such as different axes and uneven weld seams; some pipelines are welded automatically by welding devices, but the existing welding devices usually require multiple During the specific operation, there are technical problems that are difficult to match and weld adjustment is difficult to ...

In the process of laying steel structure pipelines, the welding of pipe joints is the top priority. At present, most of the pipeline welding adopts manual welding. Manual welding is not only time-consuming and laborious, but also prone to low welding accuracy and pipeline failure. Problems such as different axes and uneven weld seams; some pipelines are welded automatically by welding devices, but the existing welding devices usually require multiple In the specific operation, there are technical problems that are difficult to match, such as difficult to adjust the welding seam, etc.
