[0023] The hollow rack frame 681 is provided with a guide groove 688, and the second rack 683 is connected with a guide column 689 which slides in the guide groove 688.

[0024] The laser pipe cutting machine rack 1 is slidably connected with a movable pneumatic chuck assembly 2, and the laser pipe cutting machine rack 1 is connected with a fixed pneumatic chuck assembly 3 on one side of the top.

[0025] The first rack 7 and the second rack 683 are made of wear-resistant material and coated with a lubricating coating on the surface.

[0026] Working principle: the first servo motor 66 starts, drives the driving pulley 67 to drive the driven pulley 64 to rotate, thereby driving the rotating shaft 63 to rotate. The rotating shaft 63 is engaged with the first rack 7 through the first gear 65, thereby pushing the moving plate 62 to move along the guide rail direction, and then adjusting the distance between the two movable platforms 6. When the two movable platforms 6 are adjusted to the appropriate distance of the pipe, the pipe is placed on the two V-shaped pipe supporting frames 687.

The lifting device 68 includes two hollow rack frames 681, and is driven by the second servo motor 685 to drive the transmission shaft 684, which drives the second gear 685 to rotate. The second rack 683 slides up and down in the hollow rack frame 681 through the engagement with the second gear 685, thereby pushing the lifting plate 680 to rise and fall, ensuring that the pipe can be smoothly lifted and placed at the required position. Once the pipe is conveyed to the position by the feeding device, the pneumatic chuck assembly 2 on the laser pipe cutting machine rack 1 automatically clamps the pipe to ensure that the pipe is fixed at the predetermined position. The fixed pneumatic chuck assembly 3 cooperates with the movable pneumatic chuck assembly 2 to ensure the stable clamping of the pipe. After the positioning and clamping of the pipe are completed, the laser pipe cutting machine enters the cutting state. After completing the feeding of a pipe, the movable platform 6 will return to the initial position along the guide rail 5 again, preparing for the feeding process of the next pipe. The lifting device 68 and other mechanical parts are reset or remain in the current state as needed, ready to provide feeding support for the next workpiece at any time.
