The rotating wheel 3.5 is rotated according to the outer diameter of the pipe, driving the vertical screw 3.6 to rotate relative to the threaded sleeve 3.7, thereby causing the plate frame 3.1 to move vertically under the guidance of the linear bearing 3.8 and the guide rod 3.9 to ensure horizontal support for the pipe. The pipe is supported on two inclined rollers 3.4, which can prevent the pipe from slipping left and right and reduce friction resistance during axial movement of the pipe.

A support plate 4.3 is fixed to the outer peripheral wall of the fixed ring 4.2, located behind the arcuate notch 4.2.1. A shaft hole 4.3.1 is provided in the middle of the support plate 4.3. A servo motor 8 is mounted on the rear wall of the support plate 4.3. The front end of the power output shaft of the servo motor 8 passes through the shaft hole 4.3.1 and is then fixedly mounted with a gear 9. Sliders 4.5 are fixed to either side of the bottom end of the support 4.1. Slide rails 13 are fixed longitudinally on both sides of the top surface of the support platform 1, correspondingly sliding and engaging with the slides 4.5.

[0040] Rotate the annular plate 7.1, which drives the support rod 6.3 through the arc-shaped slide groove 7.1.1, causing the slide rod 6.1 and the clamping block 6.2 to move toward the center of the cylinder 5.1 until the multiple clamping blocks 6.2 clamp the pipe. Use a wrench to rotate the tightening bolt 7.3 to fix the annular plate 7.1 relative to the cylinder 5.1, thus completing the clamping and fixing of the pipe.

[0041] The wheel 3.5 is rotated to adjust the support height of the roller 3.4 to ensure that the pipe is in a horizontal state.

[0042] The servo motor 10 drives the driving screw 11 to rotate, and the rotating driving screw 11 drives the longitudinal moving part 4 to move backward under the guidance of the slide rail 13 through the threaded sleeve 4.4, so as to realize the axial movement of the pipe, so that the part to be cut of the pipe moves to the cutting position of the laser cutting part 2.

[0043] The servo motor 8 drives the gear 9 to rotate, and the gear 9 drives the rotating part 5 to rotate circumferentially as a whole through the ring gear 5.3 to realize the circumferential rotation of the pipe, so as to rotate the position of the pipe to be cut to the position corresponding to the cutting head of the laser cutting part 2.

[0044] And ultimately achieve efficient laser cutting of pipes.
