Description

Technical Field

[0001] The utility model relates to the technical field of mechanical manufacturing, in particular to a round pipe welding tool. Background Art

[0002] Welding, also known as fusion or melting, is a manufacturing process and technology that uses heat, high temperature or high pressure to join metals or other thermoplastic materials such as plastics. There are many sources of energy for modern welding, including gas flame, arc, laser, electron beam, friction and ultrasonic.

[0003] The Chinese utility model patent (authorization announcement number: CN214601536U name: a round tube fixture) includes a bottom plate, on which two clamping blocks are arranged, and the two clamping blocks are arranged on opposite sides with a downward tilt from the ends away from each other to the direction of approaching each other, and a certain gap is formed at the bottom end of the side of the clamping blocks approaching each other to form a clearance groove, and a clamping plate is slidably connected above the clamping block, and the clamping plate slides up and down. The present application places a round tube between two clamping blocks, and slides down and presses the round tube tightly through the upper clamping plate. The three-sided positioning and clamping can improve the clamping stability, reduce the vertical displacement of the round tube in any direction, and thus improve the processing accuracy. The setting of the yield groove can facilitate the processing of the tube wall of the round tube. The clamping plate slides up and down and cooperates with the inclined surface of the clamping block to adapt to a certain range of tube diameter changes. However, when welding steel tubes, people generally hold the steel tubes for rotation welding. During the welding process, the hands are prone to shaking, resulting in inaccurate steel tube welding, affecting the later use of the steel tube. In addition, when holding the steel tube for rotation welding, the user is prone to sore hands after working for a period of time, which makes the steel tube welding work inefficient.
