[0002] A fiber laser cutting machine uses a fiber laser generator as a light source. It outputs a high-energy-density laser beam and focuses it on the surface of the workpiece, causing the area on the workpiece irradiated by the ultra-fine focal spot to instantly melt and vaporize. It is usually used for cutting iron plates.

[0003] In order to ensure balance when adjusting the cutting angle, reduce errors and improve cutting accuracy, existing laser cutting machines use a dynamic balance adjustment structure for the laser cutting machine beam to improve stability. However, the laser cutting machine generates heat during the laser cutting process, and long-term operation will cause the beam to easily undergo thermal deformation, thereby reducing the cutting accuracy and quality. Therefore, this application proposes a dynamic balance adjustment structure for the laser cutting machine beam. Summary of the Invention

[0032] Example

[0033] like Figure 1 and Figure 2 As shown, the dynamic balance adjustment structure of the laser cutting machine beam proposed in the utility model includes a laser cutting machine body 1, and also includes two fixing frames 2 arranged on the top of the laser cutting machine body 1, an adjusting shaft 3 is rotatably installed between the fixing frames 2, a crossbeam 4 is fixed on the adjusting shaft 3, a cutting gun head is arranged under the crossbeam 4, the adjusting shaft 3 is used to adjust the cutting angle of the cutting gun head, and a fixing plate 5 is fixed on the side of the adjusting shaft 3 close to the crossbeam 4.

[0034] In addition, two guide rails 6 are symmetrically installed on the top of the laser cutting machine body 1, and guide blocks 7 are slidably installed in the guide rails 6. The bottom end part of the fixed frame 2 is fixedly connected to the guide block 7. A motor 8 is fixedly installed on one fixed frame 2, and the output shaft of the motor 8 is fixedly connected to the adjustment shaft 3. The guide rail 6 is an electric slide rail. The controller in the existing technology can be used to control the guide block 7 to slide back and forth on the guide rail 6 to adjust the position of the cutting gun head to facilitate cutting of materials. At the same time, the motor 8 is started to rotate the adjustment shaft 3 to drive the cutting gun head to rotate and adjust the cutting angle.

[0035] It is worth noting that a rectangular groove 9 is provided on the top of the laser cutting machine body 1, a shelf plate 10 is fixed on the inner wall of the rectangular groove 9, and a plurality of groups of hole grooves 11 are provided on the shelf plate 10. A connecting pipe 12 connected to the rectangular groove 9 is fixedly installed on one side of the laser cutting machine body 1, and a chip removal fan is provided in the connecting pipe 12. When the material is cut, the debris generated can be better collected by the chip removal fan through the hole groove 11 into the rectangular groove 9.

[0036] like Figures 1-4 As shown, the device also includes a stable balancing device, which is arranged on the fixed frame 2 and is used to stabilize the laser cutting machine when adjusting the cutting angle. The stable balancing device includes a mounting frame 13 fixedly mounted on a fixed frame 2, and an electric telescopic rod 14 is fixedly mounted on the side of the mounting frame 13 close to the crossbeam 4. The electric telescopic rod 14 is fixedly connected to a connecting piece 15, and a fixed rod 16 is fixedly mounted on the connecting piece 15. The electric telescopic rod 14 is a prior art, and the extension of the electric telescopic rod 14 can be used to drive the extension and movement of the fixed rod 16;

[0037] Furthermore, a positioning rod 17 is fixedly mounted on the crossbeam 4, and the positioning rod 17 is connected to a vibration-damping block 18 fixed on the adjustment shaft 3. The vibration-damping block 18 is provided with multiple sets of fixing grooves 19 that match the fixing rod 16. The extension of the electric telescopic rod 14 can be used to drive the fixing rod 16 to extend and move, so that the fixing rod 16 is stuck in the fixing groove 19, thereby completing the fixed vibration reduction of the cutting gun head after adjusting the cutting angle, thereby improving the stability and balance of the cutting;

[0038] Furthermore, the vibration damping block 18 and the fixed plate 5 are both fixed on the adjustment shaft 3 in an arc shape, that is, when the adjustment shaft 3 rotates, the cutting gun head and the vibration damping block 18 and the fixed plate 5 rotate and adjust together, and the fixing grooves 19 are evenly arranged in a circular array on the surface of the vibration damping block 18.

[0039] like Figure 3-Figure 5 As shown, the device also includes a cooling device, which is arranged on the fixed disk 5 and is used to control the thermal deformation of the beam 4 during the laser cutting process. The cooling device includes a slide 23 fixedly mounted on the fixed disk 5, and a slider 24 is slidably mounted in the slide 23. A support rod 25 is fixedly mounted on the slider 24, and a cooling plate 22 is fixedly connected to the support rod 25. The movement of the slider 24 can drive the movement and adjustment of the cooling plate 22, thereby expanding the cooling range of the cooling plate 22 and achieving a better cooling effect.

[0040] Furthermore, a heat-conducting column 20 is fixedly installed on the beam 4, and the heat-conducting column 20 is fixedly connected to the heat sink 21. The cooling plate 22 and the heat sink 21 are slidably connected. The heat-conducting column 20 can conduct the heat accumulated on the beam 4 due to laser cutting and transfer it to the heat sink 21 for heat dissipation. The cooling plate 22 allows the heat on the heat sink 21 to be dissipated more quickly.

[0041] Among them, a reciprocating screw 26 threadedly connected to the slider 24 is rotatably installed in the slide groove 23, and a driving motor 27 is fixedly installed on one side of the slide groove 23. The output shaft of the driving motor 27 is fixedly connected to the reciprocating screw 26. When the driving motor 27 is started, the reciprocating screw 26 rotates, and the slider 24 can drive the cooling plate 22 to slide back and forth on the heat dissipation plate 21, thereby expanding the cooling area range of the cooling plate 22 and improving the heat dissipation effect.

[0042] The working principle of this embodiment is as follows: starting the motor 8 causes the adjusting shaft 3 to rotate, so that the cutting gun head adjusts the cutting angle as the adjusting shaft 3 rotates. When the cutting angle is determined, the extension of the electric telescopic rod 14 is used to drive the fixed rod 16 to move forward, so that the fixed rod 16 can be stuck in the fixed groove 19, and the vibration reduction connection of the vibration reduction block 18 is cooperated, so that the laser cutting machine is more stable when adjusting the angle cutting, and a certain error is reduced. Starting the drive motor 27 causes the reciprocating screw 26 to rotate, and the slider 24 drives the cooling plate 22 to reciprocate along the slide groove 23, so that the cooling plate 22 can slide back and forth on the heat sink 21, and the heat conducted by the heat conducting column 20 causes the heat sink 21 to dissipate heat, expanding the cooling effect range of the cooling plate 22, so that the heat on the heat sink 21 can be dissipated more evenly and quickly, avoiding thermal deformation caused by excessive heat on the beam 4, and improving the cutting accuracy and quality of the laser cutting machine.

[0043] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art may make various alternative improvements and combinations to the above specific embodiments.
