Multi-station universal welding tool and welding method based on tool

Abstract

The invention discloses a multi-station universal welding tool and a welding method based on the tool. The multi-station universal welding tool comprises two symmetrically-arranged supports; each support is vertically provided with a sliding groove; a base is arranged between the two supports; the base can be adjusted in the sliding grooves in an up-down sliding manner and can rotate with the connecting positions of the base and the sliding grooves as the center; at least two installing bases are arranged on the base in the length direction of the base; each installing base is detachably provided with a welding fixing head; and each welding fixing head is formed by stacking cylindrical combined pieces from bottom to top, wherein the cylindrical combined pieces are arranged from large to small, and the welding fixing head is of a step-shaped structure. The multi-station universal welding tool can be suitable for welding of copper pipes different in pipe diameter, die replacement is not needed, and the work efficiency is effectively improved; meanwhile, arrangement and placement are convenient, the base can move up and down to adjust the position or rotate by an angle, the multi-station universal welding tool adapts to welding work of copper pipes different in shape or angle, and usage is convenient; and the welding method based on the welding tool is simple, and batched welding is achieved.

Description

technical field [0001] The invention relates to the field of welding tool technology, in particular to a multi-station universal welding tool and a welding method based on the tool. Background technique [0002] At present, most of the molds in the existing tooling for copper pipe welding are fixed molds. When welding, it is necessary to replace the mold with a suitable size according to the diameter of different copper pipes. The work efficiency is low. At the same time, there are many types of molds, resulting in Too many molds are stacked on site, which is not conducive to site management. And the tightness is poor, and more oxide scales are likely to be generated in the copper pipe during use, which will cause the whole system to be dirty, and may even cause the system to be blocked. For some small fittings with different angles (such as high and low pressure switches, needle valves, process pipes) and other tubular copper pipes, the adaptability is weak and it is incon...

AI Technical Summary

Problems solved by technology

[0004] 1. There are many different types of moulds, which need to be replaced according to the pipe diameters passed during use, and the work efficiency is low. At the same time, excessive stacking of molds on site is not conducive to on-site management

[0005] 2. It is easy to produce more oxide skin in the copper tube, which affects the overall welding quality

[0006] 3. The adaptability to some accessories with different angles is weak, and it is inconvenient to carry out welding work
