The first motor 13 is installed on a support base 10. The output end of the first motor 13 is coaxially fixedly connected to one end of the rotating shaft 11. By starting the first motor 13, the output end of the first motor 13 rotates to drive the rotating shaft 11 to rotate, the rotating shaft 11 drives the gear 12 to rotate, the gear 12 drives the gear ring 9 to rotate, and the gear ring 9 drives the rotating ring 7 to rotate in the two circular slide rails 6; like Figure 3 and Figure 5As shown, the clamping and conveying mechanism is arranged in the clamping frame 5, which is used to clamp, fix and convey the pipe 2. In order to clamp the pipe 2 and drive the pipe 2 to move along the slide 3, the clamping and conveying mechanism includes a moving frame 14, a support shaft 15, a clamping roller 16 and a second motor 17. Two moving frames 14 are symmetrically arranged in the fixed frame. The two moving frames 14 are arranged in the clamping frame 5 through the second driving member. In order to avoid the collision between the clamping frame 5 and the moving frame 14 and the workbench 1 when the clamping frame 5 and the moving frame 14 rotate, the width of the clamping frame 5 and the moving frame 14 is smaller than the width of the through slot. The support shaft 15 is rotatably arranged in the moving frame 14, the clamping roller 16 is sleeved on the support shaft 15 and is coaxially fixedly connected to the support shaft 15. An arc-shaped depression is provided on the clamping roller 16, and the axis of the arc-shaped depression is on the same horizontal line as the axis of the chute 3. In order to increase the friction force on the pipe 2, a rubber sleeve 26 is sleeved on the clamping roller 16. The second motor 17 is installed on the moving frame 14. The output end of the second motor 17 is coaxially fixedly connected to one end of the support shaft 15. The two second motors 17 are of the same model. In order to drive the two clamping rollers 16 to move toward each other to clamp the pipe 2, the second driving member includes a clamping plate 18, two screws 19, The connecting shaft 20 and the third motor 21 are provided with two movable grooves that cooperate with the clamping plate 18 in the clamping frame 5. One end of the clamping plate 18 slides with the inner wall of the movable groove. The screw 19 is rotatably set in the movable groove. The screw 19 is threadedly matched with one end of the clamping plate 18. The connecting shaft 20 is rotatably set in the fixed frame. The two ends of the connecting shaft 20 are respectively coaxially fixedly connected with one end of the two screws 19. The third motor 21 is installed on the fixed frame. A mounting groove that cooperates with the third motor 21 is provided on a fixed seat 8. The output end of the third motor 21 is coaxially fixed with the other end of a screw 19. The shafts are fixedly connected. In order to make the two clamping plates 18 move toward each other, the threads of the two screws 19 rotate in opposite directions. By starting the third motor 21, the output end of the third motor 21 rotates to drive one screw 19 to rotate, and the screw 19 drives the connecting shaft 20 to rotate, and the connecting shaft 20 drives the other screw 19 to rotate. The threads of the two screws 19 rotate in opposite directions, so the two screws 19 respectively drive the two clamping plates 18 to move toward each other, and the two clamping plates 18 drive the two moving frames 14 to move toward each other, and the two moving frames 14 drive the two clamping rollers 16 to move toward each other, and the two clamping rollers 16 press against the pipe 2; like Figure 1 and Figure 6As shown, the auxiliary abutment is provided on the output end of the electric cylinder 4, and is used to longitudinally abut and fix the pipe 2. In order to cooperate with the electric cylinder 4 to pre-longitudinally abut the pipe 2, and the abutment position is on one side of the cutting position, the auxiliary abutment includes a mounting plate 22, a telescopic rod 23, a spring 24 and an extrusion plate 25. One end of the mounting plate 22 is fixedly connected to the output end of the electric cylinder 4, and the other end of the mounting plate 22 is installed with a laser cutting head 27. The laser cutting head 27 is a fiber laser, which uses a rare earth element-doped optical fiber as a gain medium to convert electrical energy into laser light. The output wavelength near-infrared light is used to cut the pipe 2. One end of the telescopic rod 23 is fixedly connected to the other end of the mounting plate 22.

The other ends of the telescopic rod 23 and the spring 24 are fixedly connected to one end of the extrusion plate 25. The other ends of the telescopic rod 23 and the spring 24 are fixedly connected to one end of the extrusion plate 25. In order to be able to press the pipe 2 longitudinally, the other end of the extrusion plate 25 is in an arc shape. When the spring 24 is subjected to the gravity of the extrusion plate 25 , the spring 24 is stretched. At this time, the extrusion plate 25 is under the laser cutting head 27. The damping coefficient of the spring 24 is relatively high, and it is difficult for the spring 24 to drive the extrusion plate 25 up and down to shake. The telescopic rod 23 guides the spring 24, starts the electric cylinder 4 and the laser cutting head 27, and the output end of the electric cylinder 4 pushes the mounting plate 22 to move downward. The extrusion plate 25 contacts the pipe 2 in advance and presses against the pipe 2. The other end of the extrusion plate 25 is arc-shaped and slides with the pipe 2. The spring 24 and the telescopic rod 23 are both contracted, and the spring 24 generates elastic force on the pipe. The longitudinal extrusion force is applied to the pipe 2. Under the subsequent drive of the electric cylinder 4, the laser cutting head 27 is on the surface of the pipe 2 and cuts it. The rotating mechanism drives the pipe 2 to rotate, so that the laser cutting head 27 performs circumferential cutting on the pipe 2. After the cutting is completed, the output end of the electric cylinder 4 returns to the initial position. By starting the two second motors 17 at the same time and the rotation directions of the two second motors 17 are consistent, the support shaft 15 is driven to rotate.

By starting the third motor 21, the output end of the third motor 21 rotates to drive a screw 19 to rotate, and the screw 19 drives the connecting shaft 20 to rotate, and the connecting shaft 20 drives another screw 19 to rotate. The two screws 19 have opposite thread rotation directions, so the two screws 19 respectively drive the two clamping plates 18 to move toward each other, and the two clamping plates 18 drive the two moving frames 14 to move toward each other, and the two moving frames 14 drive the two clamping rollers 16 to move toward each other, and the two clamping rollers 16 press against the pipe 2, start the electric cylinder 4 and the laser cutting head 27, and the output end of the electric cylinder 4 pushes the mounting plate 22 to move downward, and the extrusion plate 25 pre-contacts the pipe 2 and presses against the pipe 2, and the other end of the extrusion plate 25 is circular The laser cutting head 27 is located on the surface of the pipe 2 and cuts the pipe 2. At the same time, the first motor 13 is started. The output end of the first motor 13 rotates to drive the rotating shaft 11 to rotate. The rotating shaft 11 drives the gear 12 to rotate. The gear 12 drives the gear ring 9 to rotate. The gear ring 9 drives the swivel 7 to rotate in the two circular slide rails 6. The swivel 7 drives multiple fixed seats 8 and the clamping frame 5 to rotate, so that the laser cutting head 27 performs circular cutting on the pipe 2. After the cutting is completed, the output end of the electric cylinder 4 returns to the initial position. By starting the two second motors 17 at the same time and the rotation directions of the two second motors 17 are consistent, the support shaft 15 is driven to rotate. The support shaft 15 drives the clamping roller 16 to rotate, so that the cut pipe 2 is transported and the next cutting is carried out.
