Therefore, CNC laser cutting machine tools are widely used in various fields. They are widely used in metal processing, machinery manufacturing, automobile manufacturing, aerospace and electronic manufacturing, etc., and are a very important processing equipment.

[0003] In the laser cutting process, the beam part of the laser head is one of the key components, which is used to generate a high-energy laser beam to cut materials. However, the laser head may be disturbed by external light, causing the beam part to produce mixed light and blur, thereby affecting the cutting accuracy and possibly causing the cutting edge to be uneven, further affecting the cutting quality. When a cutting operation is completed, the cutting position of the workpiece remains in place, and the cutting surface of the workpiece is not separated immediately, which may cause the first cutting to be forgotten, and then a second cutting may be performed.

The inner end of the tangent area 72 is movably connected to the four corners of the center rod 71. The bottom side of the placement rack 73 is movably connected to the top of the tangent area 72. When the cutting operation is completed, the supporting force of the guide frame 10 disappears, the surface of the placement rack 73 resumes upward movement, and the workpiece to be cut can be slightly away from the original placement position.

At the cutting track, the support frame 722 can be pressed downward to reduce its height, which is adjusted by the elastic shaft 723.

[0034] Working principle: Figure 1-Figure 2 As shown, the workpiece is located on the top side of the support mechanism 7, and is controlled at the control panel 9. The slide rail mechanism 2 moves forward and backward at the guide rail 8. The slider 22 slides forward and backward on the outer side of the guide rail 8, driving the side wall of the movable frame 21 to move forward and backward. The side wall of the movable frame 21 drives the side wall of the driver 3 to move in the Y-axis position, thereby driving the position of the power machine 4 to move, and finally changing the X-axis position of the cutting mechanism 5.

[0035] like Figure 1 and Figure 3 As shown, the position of the cutting mechanism 5 is controlled, and the position of the power machine 4 can drive the cutting mechanism 5 to slide left and right at the side wall of the driver 3, so as to complete the movement of the X-axis, and can determine that the bottom end of the laser head 53 is located at the top side of the support mechanism 7 from left to right.

The workpiece is placed on the top side of the placement frame 73, and the bottom of the laser head 53 is located at the top side of the workpiece for cutting. The laser beam at the bottom of the laser head 53 can be maintained in line with the straight track of the docking area 11. In the cutting track, the support frame 722 can be pressed downward to lower its height, which is adjusted by the elastic shaft 723. When the cutting operation is completed, the supporting force of the guide frame 10 disappears, and the surface of the placement frame 73 resumes upward movement.
