The pipe cutting machining efficiency of the laser pipe cutting machine is high, and the laser pipe cutting machine is widely applied to the field of machinery. When the pipe is cut, two ends of the steel pipe are erected on two chucks of the laser pipe cutting machine, the laser cutting head cuts the steel pipe between the two chucks.

When the length of the steel pipe is longer, the distance between chucks for supporting the two ends of the steel pipe is longer, the steel pipe can generate certain downward deflection due to dead weight, namely, the steel pipe is bent downwards, and the bending downwards is most obvious at the center of the length of the steel pipe; the deflection problem exists when the length of the steel pipe is too long and is affected by vibration or other reasons; the phenomena of bending downwards and swinging, especially the thin-wall long tube, lead the actual center of the steel tube to deviate from the theoretical center position, thereby influencing the cutting position accuracy of the front-stage laser cutting on the steel tube body and deviating from the actual correct cutting position. In addition, because the pipe walls of the steel pipes are thick and thin, the pipe diameters are different, and the section shapes of the steel pipes are different, the steel pipes of different types cannot be effectively supported at the same time to eliminate the deviation from the center position, so that the cutting precision is affected.
