The fixed seat is provided with a through hole that matches the handle's rotational travel. The handle is rotated downward about the hinge axis between the handle and the fixed seat, so that the round rod can move with the rotation of the handle driven by the connecting rod. At the same time, the round rod can only move in the vertical direction due to the limiting effect of the sleeve, thereby driving the pressure head at the bottom to move downward, cooperating with the support plate to press down and fix the pipe to achieve positioning.

[0007] The following improvements are made in the present application: a plurality of support plates 2 are provided on the support column located on the innermost concentric arc in the height direction, and a connecting column 2 is provided on one side end of the innermost concentric arc, a plurality of fixing plates are provided on the connecting column 2 in the height direction, and a second pipe joint is embedded in the fixing plate.

[0009] The following improvement is made in the solution of the present application: a connecting seat is provided between adjacent pipe clamps, and a third pipe joint is embedded in the top of the connecting seat.

[0010] Compared with the prior art, the present invention provides an assembly welding tool for irregular pipes, which has the following beneficial effects:

[0011] The utility model adopts a unified overall tooling to replace the original multiple auxiliary splicing tooling, and sets a multi-layer fixing unit arranged in a concentric arc curve with the center of the base as the center of the circle. When in use, the pipe fitting is first inserted into the first pipe joint in the V-shaped groove for limiting the position, and then different pipes are placed along multiple support columns distributed at equal intervals on the concentric arc for support, and pressed down and fixed with clamps. Finally, the above-mentioned overlapping positions are welded and fixed using welding equipment, which can avoid product problems caused by tooling installation errors and effectively improve welding efficiency. At the same time, the groove limiting structure on the end connecting column cooperates with the clamping piece to effectively improve the positioning accuracy and efficiency of the pipe and avoid dimensional deviation during the welding process.
