[0028] Please refer to Figure 2 , Figure 5 , Figure 6As an embodiment of the utility model, the laser cutting component 6 includes two symmetrically arranged support frames 601, wherein a lifting platform 602 is installed between the two support frames 601, and the two ends of the lifting platform 602 are respectively movably connected to the support frames 601; a laser tube 603 is arranged above the lifting platform 602, wherein the laser tube 603 is fixedly connected to the lifting platform 602 through a laser tube clamp 604; an active synchronous pulley 605 and a driven synchronous pulley 606 are respectively arranged at both ends of the lifting platform 602, wherein the active synchronous pulley 605 and the driven synchronous pulley 606 are connected through a synchronous belt 607; a reduction motor 608 is arranged on the lifting platform 602 near the active synchronous pulley 605, wherein The output shaft of the reduction motor 608 is fixedly connected to the active synchronous pulley 605; a connecting plate 609 is fixedly installed on the synchronous belt 607, wherein the other end of the connecting plate 609 extends out of the side of the lifting platform 602 and is fixedly connected to a laser head 610; a first reflector 611 is provided at the emitting end of the laser tube 603, a second reflector 612 is provided on one side of the first reflector 611, wherein a third reflector 613 is provided above the connecting plate 609; a first limiting guide rail 10 is provided below the synchronous belt 607 along its transmission direction, wherein a first guide rail slider 11 adapted to the first limiting guide rail 10 is installed below the connecting plate 609, and the first guide rail slider 11 can slide linearly along the first limiting guide rail 10.

[0029] In the above scheme, when the laser cutting assembly 6 is in the initial position, the lifting platform 602 is at a preset starting height, the laser tube 603 is fixed on the lifting platform 602 by the laser tube clamp 604 to ensure stable laser emission, the first reflector 611 and the second reflector 612 are respectively installed at the emission end of the laser tube 603, wherein the first reflector 611 and the second reflector 612 are arranged at a certain angle; the third reflector 613 is arranged above the connecting plate 609 and is perpendicular to the reflection angle of the second reflector 612, wherein the laser tube 603 emits a laser beam, the laser beam is first reflected by the first reflector 611, and its propagation direction is changed.

[0032] In the above-described scheme, ball screws 12 are respectively provided at both ends of the lifting platform 602, and the nut of the ball screw 12 is fixedly connected to the lifting platform 602, so that the height change of the lifting platform 602 is achieved by the rotation of the ball screw 12 and the up and down movement of the nut; the lower end of the ball screw 12 passes through the lifting platform 602 and is movably connected to the bottom end of the support frame 601, and the upper end of the ball screw 12 passes through the top of the support frame 601 upward and extends outward. This design allows the ball screw 12 to rotate freely in the lifting platform 602, while supporting the lifting platform 602 and transmitting the lifting force; the servo motor 13 is installed in the support frame 6 01, its output shaft is fixedly connected to the ball screw 12, wherein the servo motor 13 serves as a power source for driving the ball screw 12 to rotate, and the height of the lifting platform 602 can be accurately adjusted by accurately controlling the rotation of the servo motor 13; by arranging a plurality of limit guide pillars 14 around the ball screw 12, the upper ends of these limit guide pillars 14 are fixedly connected to the top of the support frame 601, and the lower ends pass through the lifting platform 602 and are fixedly connected to the bottom of the support frame 601, wherein the function of the limit guide pillars 14 is to limit the moving range of the lifting platform 602 in the vertical direction to prevent it from excessive lifting or tilting.

[0033] Furthermore, when the height of the lifting platform 602 needs to be adjusted, the servo motor 13 starts to rotate, so that the rotation of the servo motor 13 is transmitted to the ball screw 12 through the output shaft, and the ball screw 12 starts to rotate under the drive of the servo motor 13; because the nut of the ball screw 12 is fixedly connected to the lifting platform 602, when the ball screw 12 rotates, the nut will move up and down along the axis of the ball screw 12, thereby driving the lifting platform 602 to perform lifting and lowering movements, thereby achieving precise adjustment of the height of the lifting platform 602 and meeting the requirements of high-precision processing or positioning; in the process of lifting the lifting platform 602, the limit guide column 14 will play a limiting role to ensure that the lifting platform 602 moves within a preset range to avoid accidents.

[0035] In the above-described scheme, when the laser cutting component 6 needs to be moved, the driving motor 1501 starts to work, wherein the output end of the driving motor 1501 drives the driving gear 1505 to rotate. Since the driving gear 1505 is meshed with the driven gear 1506, when the driving gear 1505 rotates, the driven gear 1506 also rotates accordingly. The rotation of the driven gear 1506 drives the driven pulley 1503 to rotate, thereby causing the belt 1504 to start moving; since the belt 1504 is fixedly connected to the bottom of the support frame 601, when the belt 1504 moves, the support frame 601 also moves accordingly; in order to ensure the accuracy of the laser cutting component 6 during movement In order to improve the stability, the translation component 15 is also provided with a second limiting guide rail 16 and a second guide rail slider 17, wherein the second limiting guide rail 16 is arranged on the inner side of the belt 1504 and is parallel to the long side of the workbench 2, and the bottom of the support frame 601 is provided with a second guide rail slider 17 adapted to the second limiting guide rail 16.
