Description

Technical Field

[0001] The utility model relates to the technical field of welding fixtures, in particular to an anti-shake positioning welding fixture for metal products. Background Art

[0002] Welding is a commonly used connection method between metals or thermoplastic materials, also known as fusion welding. It is a manufacturing process and technology that joins metals or other thermoplastic materials by heating, high temperature or high pressure. Its principle is a process in which two or more similar or dissimilar materials are connected into one through the combination and diffusion between atoms or molecules. When welding metal pipe fittings, it is necessary to ensure that the size after welding is accurate, and the pipe fittings must be accurately positioned. Manual positioning has poor positioning accuracy, is time-consuming and labor-intensive, and affects work efficiency. The temporary simple welding tooling has poor versatility and cannot be used for welding and clamping pipe fittings of various sizes, and the operation is more troublesome.

[0003] After searching, a metal pipe butt welding fixture disclosed in the prior art (application number: CN201821580118.6) records in the text that "the lower part of the base is welded with a support leg, the base is provided with a slide rail, and the first pipe clamp and the second pipe clamp are installed on the slide rail; the first baffle plate and the second baffle plate are respectively provided at both ends of the base, and a support seat is provided in the middle of the base, and the first screw rod is installed between the first baffle plate and the second baffle plate, and the first screw rod passes through the support seat, the first pipe clamp and the second pipe clamp; the first pipe clamp and the second pipe clamp are both connected to the first screw rod by threads; a first hand wheel is provided on the right side of the first screw rod."; The pipe clamp of the fixture clamps the pipe fittings by the hand wheel, and clamps It is fast and easy to operate, and a gasket is arranged in the pipe clamping groove, which ensures stable clamping and prevents scratches on the surface of the pipe fitting. At the same time, the two pipe clamps are installed on the same slide rail. After the pipe fitting is clamped, the concentricity is high and the positioning is accurate. However, the first screw rod of the clamp is directly exposed to the outside world. When welding metal products, the high-temperature welding wire may fall on the surface of the first screw rod due to improper operation of the workers, which will increase the probability of transmission failure of the first screw rod. In addition, the clamp cannot conveniently adjust the relative positions of the two groups of metal products to be welded according to actual needs, so it is impossible to weld in unconventional positions. Manual positioning by workers will increase the probability of jitter during welding, affecting the welding effect. Utility Model Content
