Adjustable pipeline butt joint laser welding device

Abstract

The adjustable pipeline butt joint laser welding device comprises a base and a clamping and fixing mechanism, the clamping and fixing mechanism comprises a cylinder, the outer surface of the cylinder is fixedly connected with the outer surface of the base, circular rings are rotationally connected to the two sides of the outer surface of the cylinder, and the outer surfaces of the circular rings on the two sides are fixedly connected through a fixing rod; the outer portions of the circular rings on the two sides are each provided with two sets of rotating rollers, the two sets of rotating rollers are perpendicular to each other, the number of each set of rotating rollers is two, and the circular rings rotate to drive the two rotating rollers in each set to be close to each other so that a pipeline can be clamped. Relates to the technical field of pipeline machining, and solves the problems that when an existing pipeline butt joint device is used, on one hand, the non-butt-joint side of a pipeline is clamped through an inner support, so that the butt joint end is prone to deviating downwards to affect the butt joint precision, and on the other hand, large or long pipelines cannot be clamped and butt-jointed due to use limitation.
