Welding auxiliary tooling is a tool or equipment used to assist the welding process. It can ensure the precise position of the welded parts and prevent movement during welding, thereby improving welding quality and efficiency.

[0003] Since the diameter of the composite pipe has a tolerance and is not easy to align, a welding auxiliary tool is required for butt welding. Although the existing welding auxiliary tool can align the composite pipe, the overall horizontal height is low and the composite pipe can only be aligned horizontally, which causes the workers to bend over for a long time during welding, which is quite hard. In addition, due to the limited space of the tool, only two composite pipes can be aligned at a time. During batch welding, it is necessary to disassemble and assemble continuously, which reduces work efficiency. Therefore, a composite pipe welding auxiliary tool is proposed to solve the above-mentioned problems. Utility Model Content

The internal thread of the threaded hole 13 is connected to a slotted screw 16. By setting up a welding auxiliary mechanism, when in use, the staff first needs to insert the three composite pipes into the slot 14 in turn, and then press the three composite pipes into the inner side of the arc-shaped groove 12 in turn, and fix them with the fixing clamp 15 and the slotted screw 16. Subsequently, starting the driving motor 11 can drive the lifting plate 10 to move downward, so that the end faces of the composite pipes are vertically aligned, and the staff do not need to bend over for a long time to weld, which is more labor-saving, and multiple composite pipes can be aligned at one time, thereby improving work efficiency.

After alignment, keep the horizontal height of the lifting plate 10 unchanged, and then welding can be carried out. When welding is completed, release the fixing clamp 15 and the flat screw 16 for the composite pipe, and reset the lifting plate 10. Then, the staff can pull the composite pipe out of the slot 14.
