[0030] Among them, a disk 12 is fixedly connected to the support plate 10, a second motor 13 is fixedly connected to the disk 12, the output end of the second motor 13 is fixedly connected to a threaded rod 14, a threaded sleeve 15 is threadedly connected to the threaded rod 14, one end of the threaded sleeve 15 is fixedly connected to a guide post 16, a fixed block 17 is fixedly connected to the disk 12, a clamping rod 18 is rotatably connected to the fixed block 17, a clamping block 19 is slidably connected to the clamping rod 18, one end of the clamping rod 18 is rotatably connected to a clamping column 20, a rotating disk 21 is rotatably connected to the clamping block 19, a guide plate 22 is fixedly connected to the rotating disk 21, a fourth guide groove 23 is provided on the guide plate 22, a support leg 24 is fixedly connected to the lower part of the processing table 1, the slider 5 is slidably connected in the first guide groove 6, the pushing block 7 is located on one side of the limit post 8, several groups of third guide grooves 11 are provided, the bottom end of the pushing block 7 is attached to the third guide groove 11, the rotating disk 21 is located on one side of the disk 12, one end of the support plate 10 slides on the processing table 1, the threaded rod 14 is rotatably connected to the disk 12, the guide post 16 penetrates and slides in the fourth guide groove 23, the shape of the guide post 16 is cylindrical, the guide plate 22 is located on one side of the threaded sleeve 15, two groups of disks 12 and rotating disks 21 are provided and are respectively located at both ends of the support plate 10, three clamping rods 18 are evenly provided on each group of disks 12. By starting the two second motors 13, while the output end of the second motor 13 drives the threaded rod 14 to rotate, it also drives the guide post 16 to move, so that the guide post 16 slides in the fourth guide groove 23 and drives the rotating disk 21 to rotate at the same time, thereby driving the clamping column 20 to clamp both ends of the seamless steel pipe. This device is applicable to steel pipes with different radius sizes, has simple operation and a wide application range.

[0031] Working principle: When using the positioning device for seamless steel pipe processing, first place the seamless steel pipe in the middle of two groups of discs 12, so that the seamless steel pipe passes through the middle of the two groups of discs 12 and the rotating disc 21. Then start two groups of motors two 13 at any time. The output end of the motor two 13 drives the threaded rod 14 to rotate on the disc 12. While the threaded rod 14 rotates, it drives the threaded sleeve 15 to rotate. At this time, the guide post 16 slides through the fourth guide groove 23, and the guide post 16 drives the guide plate 22 to rotate, thereby driving the rotating disc 21 to rotate on one side of the disc 12. While rotating, it drives three groups of clamping blocks 19 to rotate in the rotating disc 21. The clamping rod 18 slides through the clamping block 19. One end of the clamping rod 18 is rotatably connected to the disc 12, and the other end is rotatably connected with a clamping column 20 to clamp the outer wall of the steel pipe, so that both ends of the steel pipe are stably clamped and fixed on the processing table 1. Subsequently, subsequent processing work can be carried out. When it is necessary to adjust the position of the steel pipe for a small distance during processing, start the motor one 2. The output end of the motor one 2 drives the connecting rod one 3 to rotate. One end of the connecting rod one 3 drives the connecting rod two 4 to swing reciprocally, which drives the slider 5 to slide in the first guide groove 6. While the slider 5 drives the bottom end of the pushing block 7 to rotate, it drives the third guide groove 11 to move. At this time, the bottom end of the pushing block 7 fits on one side of the third guide groove 11, and the other end fits on one side of the limit post 8. Subsequently, when the slider 5 moves in the other direction, it drives the bottom end of the pushing block 7 to slide towards the other end of the third guide groove 11, so that the pushing block 7 slides into the next group of third guide grooves 11. Repeating the above steps can move the position of the steel pipe for a small distance, which is more convenient for the staff to carry out processing work. After the processing is completed, the motor two 13 can be reversed to make the clamping column 20 move away from the steel pipe. Then the processed seamless steel pipe can be taken out.
