[0036] The working principle and use process of the present invention are as follows: when in use, first, the two steel pipes are respectively sleeved on the surface of the movable sleeve 84. After the sleeve is sleeved, the cylinder 82 is started. The output end of the cylinder 82 drives the movable sleeve 84 to move inward. When the movable sleeve 84 moves inward, it drives the fixed block 85 to move inward. When the fixed block 85 moves inward, it drives the traction rod 86 and the push plate 87 to move inward. When the push plate 87 moves, the movement trajectory of the push plate 87 and the traction rod 86 becomes outward expansion through the limit of the guide rod 89. The push plate 87 drives the flaring plate 88 to expand outward, so that the surface of the flaring plate 88 is in close contact with the After the inner wall of the steel pipe is fixed, the bottom plate 2 is moved to make the steel pipes on both sides contact each other. After the contact is completed, the position of the positioning frame 5 and the positioning sleeve 7 is adjusted by the pull ring 11 so that the positioning sleeve 7 is sleeved on the surface of the steel pipe interface. After the sleeve is sleeved, the positioning sleeve 7 is passed through for welding. After a part of the welding is completed, the motor 14 is started. The output end of the motor 14 drives the right guide wheel 13 to rotate, and the right guide wheel 13 drives the turntable 83 to rotate. The turntable 83 drives the expansion plate 88 and the steel pipe to rotate. After rotating to a certain angle, welding is performed again. After welding is completed, the above operation is reversed to remove the welded steel pipe.

[0037] In summary, the steel pipe weld positioning device is configured by respectively sleeve-mounting two steel pipes on the surface of the movable sleeve 84. After the sleeve is mounted, the cylinder 82 is started. The output end of the cylinder 82 drives the movable sleeve 84 to move inward. When the movable sleeve 84 moves inward, it drives the fixed block 85 to move inward. When the fixed block 85 moves inward, it drives the traction rod 86 and the push plate 87 to move inward. When the push plate 87 moves, the movement trajectory of the push plate 87 and the traction rod 86 is changed to expand outward through the limit of the guide rod 89. The push plate 87 drives the flaring plate 88 to expand outward, so that the surface of the flaring plate 88 is in close contact with the inner wall of the steel pipe. After the fixing is completed, the steel pipes on both sides are contacted with each other by moving the bottom plate 2. After the contact is completed, the position of the positioning frame 5 and the positioning sleeve 7 is adjusted by the pull ring 11 to make the positioning The sleeve 7 is sleeved on the surface of the steel pipe interface. After the sleeve is sleeved, it is passed through the positioning sleeve 7 for welding. After a part of the welding is completed, the motor 14 is started. The output end of the motor 14 drives the right guide wheel 13 to rotate, and the right guide wheel 13 drives the turntable 83 to rotate. The turntable 83 drives the expansion plate 88 and the steel pipe to rotate. After rotating to a certain angle, welding is performed again. After welding is completed, the welded steel pipe can be removed by reversing the above operation, thereby having the advantage of welding positioning and solving the problem that most of the existing welding methods are to directly place the steel pipe on the ground or on a workbench for welding. This welding method is not only inefficient, but also the steel pipe is prone to deviation after the user accidentally touches it, resulting in a skewed weld and reduced steel pipe welding stability.
