Both ends of the second connecting plate 210 pass through the second sliding groove 104 and are connected to the second clamping plate 211. The steel pipe is placed on the surface of the placement block 102. The first motor 201 drives the bidirectional threaded rod 202 to rotate, causing the first threaded cylinder 203 and the second threaded cylinder 204 to move. In coordination with the first slide rail 206 and the first slider 205, the second slider 209 and the first connecting plate 207, the second connecting plate 210 and the first sliding groove 103 and the second sliding groove 104, the first clamping plate 208 and the second clamping plate 211 move, and the first clamping plate 208 and the second clamping plate 211 come into contact with the steel pipe to clamp and fix the steel pipe.

[0021] Specifically, the moving mechanism 3 includes a second motor 301, which is located on the side of the frame 1. A first threaded rod 302 is installed at the output end of the second motor 301. A third threaded cylinder 303 is provided on the surface of the first threaded rod 302. The moving mechanism 3 also includes a second slide rail 304, which is installed on the side of the frame 1.

One end of the third slider 305 is connected to the third threaded cylinder 303, and one end of the third threaded cylinder 303 is connected to the moving frame 5. The second motor 301 drives the first threaded rod 302 to rotate, causing the third threaded cylinder 303 to move and cooperate with the third slider 305 and the second slide rail 304, thereby moving the moving frame 5 and thus moving the welded steel pipe to the appropriate position.

[0022] Specifically, the surface of the movable frame 5 is provided with a third sliding groove 501, and a fourth slider 502 is slidably connected inside the third sliding groove 501.

[0023] All electrical devices in this utility model are powered by an external power source;

[0024] Working principle and usage process: The steel pipe is placed on the surface of the placement block 102. The first motor 201 drives the bidirectional threaded rod 202 to rotate, causing the first threaded cylinder 203 and the second threaded cylinder 204 to move. This, in conjunction with the first slide rail 206 and the first slider 205, the second slider 209 and the first connecting plate 207, the second connecting plate 210 and the first slide groove 103, and the second slide groove 104, causes the first clamping plate 208 and the second clamping plate 211 to move, bringing them into contact with the steel pipe and clamping and fixing it. The third motor 601 drives the second threaded rod 602 to rotate, causing the fourth threaded cylinder 603 to rise and fall. This, in conjunction with the third slide groove 501 and the fourth slider 502, causes the connecting frame 5 to rise and fall, allowing the height of the welded steel pipe to be adjusted accordingly. The height of the movable connecting frame 5 is adjusted so that the welded steel pipe is placed in the middle of the connecting frame 4. The fixing plate 402 is moved by the electric push rod 401, and the fixing plate 402 is brought into contact with the welded steel pipe to fix the welded steel pipe. Then, the first threaded rod 302 is rotated by the second motor 301, which moves the third threaded cylinder 303 to cooperate with the third slider 305 and the second slide rail 304, so that the movable frame 5 is moved, thereby moving the welded steel pipe to a suitable position to bring the welded steel pipe into contact with the steel pipe for easy welding. The bidirectional threaded rod 202 is a threaded rod with two sections of threads in opposite directions symmetrically opened on its surface. When the first motor 201 drives the bidirectional threaded rod 202 to rotate, the first threaded cylinder 203 and the second threaded cylinder 204 can be brought closer to each other or moved away from each other.
