The utility model belongs to the technical field of pipeline
welding, and particularly relates to a pipeline
butt joint auxiliary device for
water supply pipeline
welding operation, which comprises a base, guide rods and a middle limit seat, the guide rods are symmetrically arranged on the base in the middle of the middle limit seat, and the guide rods penetrate through the middle limit seat. A guide rod is installed on the base,
welding moving frames are slidably arranged at the two ends of the guide rod, clamping jaws are slidably arranged on the surfaces of the welding moving frames, adjusting lead screws are rotatably arranged in inner cavities of the welding moving frames, a
servo driving motor is installed at the end of the base, and the
power output end of the
servo driving motor is in transmission connection with a driving screw shaft. The welding pipeline and the connecting
pipe head can be controlled to get close to each other and get away from each other, the welding pipeline and the connecting
pipe head can be rapidly welded by being matched with a fuse
machine, the welding efficiency of the pipeline can be improved, meanwhile, the welding pipeline moves in the horizontal direction, the welding difficulty can be reduced, and the welding precision of the pipeline can be improved.
