The clamping mechanism 2 comprises a fixing block 201 welded to the inner wall of the cylinder 1. A lower arc plate 202 is installed on the top of the fixing block 201, and an upper arc plate 203 is arranged above the lower arc plate 202. The top of the upper arc plate 203 is connected to a first cylinder 204. The pipe passes through the inside of the cylinder 1. The lower arc plate 202 provides support for the pipe. The upper arc plate 203 is controlled to descend by starting the first cylinder 204 until the upper arc plate 203 abuts against the pipe. The pipe is fixed by the clamping mechanism 2, so that the pipe remains stable during the cutting process, thereby improving the cutting quality. The outside of the cylinder 1 is rotatably connected to a circular frame 3, and a support plate 4 is integrally arranged at the bottom end of the circular frame 3. The support plate 4 A base 5 is welded to the lower end of the support plate 4, and a first motor 6 is installed on the left side of the support plate 4. The central axis of the circular frame 3 coincides with the central axis of the cylinder 1, and the cylinder 1 and the base 5 are parallel to each other. The circular frame 3 and the support plate 4 provide stable support for the cylinder 1. Since the circular frame 3 and the cylinder 1 are rotatable, the circular frame 3 provides support for the cylinder 1 without interfering with the rotation of the cylinder 1. A pinion 7 is connected to the output end of the first motor 6, and a large gear 8 is installed in the middle of the outer surface of the cylinder 1. The output shaft of the first motor 6 passes through the support plate 4 through a bearing and is connected to the pinion 7, and the pinion 7 is meshed with the large gear 8. The pinion 7 is driven to rotate by starting the first motor 6. Under the meshing action of the pinion 7 and the large gear 8, the cylinder 1 rotates slowly, and the pipe installed inside the cylinder 1 rotates accordingly, which is convenient for cutting the pipe;

[0024] The cutting mechanism 9 is arranged on the right side of the cylinder 1, and the cutting mechanism 9 includes a laser cutting head 901 and a second cylinder 902, the second cylinder 902 is arranged above the laser cutting head 901, a movable slider 10 is fixed above the cutting mechanism 9, and a screw rod 11 is passed through the inside of the movable slider 10, and a second motor 12 is connected to the right end of the screw rod 11, the screw rod 11 is rotatably connected to the baffle 14, and the movable slider 10 is threadedly connected to the outside of the screw rod 11, and the top end of the movable slider 10 is slidably fitted with the lower surface of the cross plate 13, and the screw rod 11 is driven by starting the second motor 12 The forward and reverse rotation makes the movable slider 10 threadedly connected to the outside of the screw rod 11 have the function of left and right translation, thereby controlling the position of the cutting mechanism 9, which is convenient for cutting at different positions of the pipeline. A horizontal plate 13 is arranged parallel to the top of the screw rod 11, and baffles 14 are welded to the left and right ends of the bottom of the horizontal plate 13. Connecting plates 15 are welded to the front and rear ends of the horizontal plate 13, and a longitudinal plate 16 is fixed to the lower end of the connecting plate 15. A controller 17 is installed at the front end of the longitudinal plate 16.

[0025] Working principle: When in use, first pass the pipe through the inside of the cylinder 1, and the lower arc plate 202 provides support for the pipe. The first cylinder 204 is started by the controller 17 to drive the upper arc plate 203 to descend until the upper arc plate 203 is against the pipe, and the pipe is fixed by the clamping mechanism 2. The laser cutting head 901 is controlled to descend by the second cylinder 902, and the laser cutting head 901 cuts the pipe. The first motor 6 is started to drive the pinion 7 to rotate. Under the meshing action of the pinion 7 and the large gear 8, the cylinder 1 rotates slowly. Since the annular frame 3 is rotatably connected to the outside of the cylinder 1, the annular frame 3 and the support plate 4 provide support for the cylinder 1 without interfering with the rotation of the cylinder 1. The rotation of the cylinder 1 drives the internal pipe to rotate together, so the laser cutting head 901 effectively cuts the rotating pipe. By starting the second motor 12 to drive the screw rod 11 to rotate forward and reverse, the movable slider 10 threadedly connected to the outside of the screw rod 11 has the function of left and right translation, thereby controlling the position of the cutting mechanism 9, which is convenient for cutting at different positions of the pipe.
