Automatic sealing type pipe-pipe welding machine head

Abstract

The invention discloses an automatic sealing type pipe-pipe welding machine head, and belongs to the technical field of automatic welding equipment. The automatic sealing type pipe-pipe welding machine head comprises two fixing rings which are coaxially arranged left and right, a plurality of semi-cylinders, a cambered plate, a vertical rod, a cross rod and a tension spring, wherein annular grooves are formed in the opposite surfaces of the two semicircular rings, the plurality of semi-cylinders are uniformly fixed on the outer wall of the right side fixing ring around the axis of the right side fixing ring, the two ends of the cambered plate are slidably connected with the annular grooves in the left side and the right side, a middle hole and a vertical hole are formed in the cambered plate in the thickness direction, the vertical rod penetrates through the vertical hole, the bottom of the vertical rod is in shaft connection with a roller, a roller fixing shaft is connected with an output shaft of a motor, the motor is fixed to the vertical rod, the top of the vertical rod penetrates through the middle of the cross rod, and the right end of the cross rod abuts against the outer arc face of the semi-cylinder, and the tension spring is arranged on the vertical rod in a penetrating mode. According to the automatic sealing type pipe-pipe welding machine head, welding without wire feeding is carried out, manual labor is replaced, damage to the body of a worker is avoided, and the welding efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of automatic welding equipment, in particular to an automatic sealing type pipe welding head. Background technique [0002] Welding, also known as welding, is a manufacturing process and technique that uses heat, high temperature, or pressure to join metal or other thermoplastic materials such as plastics. There are many sources of energy for modern welding, including gas flames, electric arcs, lasers, electron beams, friction, and ultrasound. In addition to its use in factories, welding can also be performed in a variety of environments, such as in the field, underwater and in space. [0003] In the actual argon arc welding work, it is often necessary to butt weld two pipes, but in the case of heavy workload, the physical exertion of the workers is serious, the damage to the eyes is serious, and the workers cannot work for a long time, resulting in delays in work progress and delay.
