[0002] Laser pipe cutting machines are widely used in industries such as oil exploration, lighting, metal processing, and hardware. They can meet the cutting requirements of various shaped pipes, can cut cylinders and intersecting holes with different directions and diameters on the main pipe, can cut inclined end faces at the ends of round pipes, and are applicable to metal pipes such as stainless steel, carbon steel, alloy steel, aluminum, copper, and titanium. Their greatest advantage is high precision and high speed.

[0003] A Chinese patent with the publication number CN218799972U discloses a pipe centering device for a laser pipe cutting machine, including a workbench. A feeding port is provided on the front of the workbench, a centering mechanism for centering the pipe is provided on the front of the workbench, and a support mechanism for supporting the pipe is provided on the back of the workbench. The centering mechanism includes a mounting plate fixed to the front of the workbench. This pipe centering device for a laser pipe cutting machine is provided with a centering mechanism and a support mechanism. Through the mutual cooperation between the structures of the centering mechanism and the support mechanism, the pipe can be effectively clamped to prevent the pipe from shifting during transportation. After the gear is rotated by the first motor, the two runners on the left and right sides clamp the pipe to improve the centering effect of the pipe, and the pipe can also be supported to prevent the pipe from warping during processing. The upper and lower support wheels are driven by the second motor to support the pipe to improve the cutting effect of the pipe.
