Butt joint mechanism for metal pipe fitting welding

Abstract

The utility model discloses a butt joint mechanism for welding metal pipe fittings, which comprises a base and side plates integrally formed with the base, the two side plates are vertically arranged, and the butt joint mechanism is characterized in that a chuck is arranged between the two side plates, is in sliding connection with the base and is driven by a driving mechanism arranged on the base; a clamping face parallel to the chuck is arranged on the side, opposite to the side plate, of the chuck, a movable clamping plate is arranged on the side plate, and the distance between the movable clamping plate and the clamping face is adjustable. Metal pipes to be welded are placed between the chucks and the side plates respectively, the ends of the two metal pipes are adjusted to be in butt joint, then the lead screw b is rotated to drive the chucks to move forwards, the metal pipes are fixed under the common clamping of the clamping faces and the side plates, follow-up welding is facilitated, the movable clamping plates can be driven through the lead screw a for the two metal pipes different in size, and the two metal pipes are fixed through the movable clamping plates. And the metal pipe with the small size is clamped, and the applicability of the metal pipe clamping device is improved.
