Circular steel tube welding machine

Abstract

The invention provides a circular steel tube welding machine. The circular steel tube welding machine comprises a supporting mechanism, a jacking mechanism and a welding mechanism. The supporting mechanism comprises two supporting bases, a supporting drive assembly is arranged below the supporting bases, and the two supporting bases can vertically rise and fall under control of the supporting drive assembly. The jacking mechanism comprises two edge movable plates, a thimble is mounted on the inner side face of each edge movable plate, and two sets of jacking drive assemblies are arranged on abase and used for controlling the two edge movable plates to synchronously and reversely move in the horizontal direction. The welding mechanism comprises a supporting disc, a drive disc and a weldinggun disc. One side of the drive disc is rotationally mounted in the supporting disc, and the other side of the drive disc is fixedly connected with the welding gun disc. According to the welding machine, circular steel tubes are welded by rotating a welding gun, the efficiency is high, as the circular steel tubes are static in the welding process, the circular steel tubes are firm and stable after being welded, and the strength of the positions of weld joints is high.

Description

technical field [0001] The invention mainly relates to the technical field of mechanical equipment, in particular to a round steel pipe welding machine. Background technique [0002] The welding of round steel pipes is to connect two sections of steel pipes by welding. The general welding method is to fix the two sections of round steel pipes butt joints, and then weld them by means of automatic welding machines or manual welding torches. Wherein, in the process of utilizing an automatic welding machine or a manual welding torch to weld, the welding of one week is generally realized by rotating a round steel pipe. However, since the two steel pipes are disconnected at the beginning, in the process of welding, it is easy to cause the disadvantage of unreliable welding by rotating the round steel pipe. The main reason is that it is difficult to ensure that the two round steel pipes are in absolute The synchronous motion state of the two circular steel pipes, so that when the ...

However, since the two steel pipes are disconnected at the beginning, in the process of welding, it is easy to cause the disadvantage of unreliable welding by rotating the round steel pipe. The main reason is that it is difficult to ensure that the two round steel pipes are in the absolute The synchronous motion state of the two round steel pipes, so that when the rotation speed of the two round steel pipes deviates slightly, it will cause the misalignment of the originally aligned steel pipes, which will affect the reliability of the weld
