[0024] Embodiment 1
[0025] The present embodiment provides a thin-walled pipe outer part welding positioning tool as shown in Figs. 1-6 The present embodiment provides a thin-walled pipe outer part welding positioning tool as shown in
[0026] In use, first, two fixed rings 1 are positioned and installed at both ends of the thin-walled pipe part, a plurality of sliding holes 4 matched with the connecting rods 2 are formed on the circumference of the fixed ring 1, the connecting rods 2 are slidably passed through the fixed ring 1 through the sliding holes 4, and then the connecting rods 2 are horizontally and coordinately installed through the sliding holes 4, wherein the connecting rods 2 are profiled materials, the positioning plates 3 are installed in the grooves of the profiled materials, and the positioning plates 3 can slide in the grooves of the profiled materials for adjusting the welding position when welding the outer part; then the positioning plates 3 on the grooves of the profiled materials are used to determine the circumferential distribution position of the outer part to be welded, the position is determined after welding, and the tool is disassembled after cooling, wherein the thermal deformation can be almost ignored due to the positioning of the device during the cooling process.
