[0030] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0031] Embodiment 1:

[0032] As Figure 1 、 2 shown, a laser cutting device includes two symmetrically arranged brackets 1, a first support plate 3, and a second support plate 4.

[0033] The two first support plates 3 are installed on opposite sides of the bracket 1, the two second support plates 4 are installed on the top of the bracket 1, a grinding assembly 2 is provided on the opposite sides of the two first support plates 3, a laser cutting assembly 5 is provided on the top of the second support plate 4, and a clamping assembly 6 for clamping the plate is further provided on one side of the second support plate 4. The grinding assembly 2 includes a first slide plate 7 slidably engaged with the opposite sides of the two first support plates 3 through an electric slide rail and a first slider 12 slidably engaged with the first slide plate 7 through an electric slide rail. A first hydraulic rod 11 is fixedly installed at the bottom of the first slider 12. The telescopic end of the first hydraulic rod 11 penetrates through the first slider 12 and is fixed with a first motor 8. The drive shaft of the first motor 8 is fixedly connected with a rotating shaft 9 through a coupling. A grinding wheel 10 is detachably installed on the outer wall of the top of the rotating shaft 9.

[0034] The first slide plate 7 slides on the first support plate 3, and the first slider 12 slides on the first slide plate 7 to adjust the horizontal position of the grinding wheel 10. After cutting, the first hydraulic rod 11 is started to drive the first motor 8, the rotating shaft 9, and the grinding wheel 10 to rise until the grinding wheel 10 contacts the back of the plate. Then, the first motor 8 is started to drive the rotating shaft 9 to drive the grinding wheel 10 to rotate to grind the slag generated by cutting. During grinding, the first hydraulic rod 11 continues to push the grinding wheel 10 upward until all the slag is ground.

[0035] This device can grind and clean the slag generated on the back of the plate by setting the grinding wheel 10, avoiding the unevenness of the back of the plate caused by slag during cutting, thereby improving the cutting efficiency and quality.

[0036] As Figure 3As shown, the laser cutting assembly 5 includes a second slide plate 13 and a laser cutting head 15. The second slide plate 13 is slidably fitted on the tops of two second support plates 4 through an electric slide rail. A second slider 14 is slidably fitted on the inner wall of the second slide plate 13 through an electric slide rail, and the laser cutting head 15 is slidably fitted with the second slider 14 through an electric slide rail.

[0037] The cooperation between the second slide plate 13 and the second support plate 4 and the second slider 14 can change the horizontal position of the laser cutting head 15, and the cooperation between the second slider 14 and the laser cutting head 15 can change the vertical height of the laser cutting head 15.

[0038] In this embodiment: The clamping assembly 6 is used to clamp and convey the plate to be cut to the laser cutting assembly 5 for cutting. After the cutting is completed, the first hydraulic rod 11 is started to drive the grinding wheel 10 to rise until the grinding wheel 10 contacts the back of the plate, and the slag generated by cutting is ground and removed.

[0039] Embodiment 2:

[0040] A laser cutting device, in this embodiment, the following improvements are made on the basis of Embodiment 1, as Figures 3 - 5 shown:

[0041] The clamping assembly 6 includes symmetrically arranged third sliders 16, a bearing bracket 18 and a threaded rod 19. The third sliders 16 are slidably fitted on the inner wall of the second support plate 4. One of the third sliders 16 is connected to one of the bearing brackets 18 through a second hydraulic rod 17, and the other third slider 16 is fixedly connected to the other bearing bracket 18 through a fixed rod 21.

[0042] The threaded rod 19 is rotatably connected to the inner wall of the bearing bracket 18 and is also slidably fitted on the inner wall of the bearing bracket 18. The clamping plate 20 is in threaded cooperation with the threaded rod 19.

[0043] A lead screw 22 is threadedly connected to the inner wall of the third slider 16 connected to the fixed rod 21. A second motor 23 is fixedly attached to the outer wall of the second support plate 4 by bolts. The output shaft of the second motor 23 is fixedly connected to one end of the lead screw 22 through a coupling.

[0044] Start the second hydraulic rod 17 to drive the connected bearing bracket 18 to move in the opposite direction to the other bearing bracket 18, pulling apart the distance between the two bearing brackets 18. Then insert one side of the plate between the bearing bracket 18 and the clamping plate 20 connected to the fixed rod 21. After the plate is laid flat, start the second hydraulic rod 17 again to drive the connected bearing bracket 18 to approach the other side of the plate until the plate is stably placed on the tops of the two bearing brackets 18. Then rotate the threaded rod 19 to make the clamping plate 20 descend to contact the plate and maintain a certain pressure, thus completing the clamping of the plate. Then start the second motor 23 to drive the lead screw 22 to rotate, and use the third slider 16 to drive the plate to move to the laser cutting assembly 5 for cutting.

[0045] The device can clamp the sheet material by setting the supporting bracket 18 and the clamping plate 20, avoiding the movement of the sheet material during grinding, which affects the grinding effect and improves the stability of the device.

[0046] By setting the threaded rod 19, the device can adjust the distance between the clamping plate 20 and the supporting bracket 18, so that the clamping assembly 6 can clamp sheet materials with different thicknesses, improving the flexible adaptability of the device.

[0047] Working principle: When the device is in use, first start the second hydraulic rod 17 to drive one of the supporting brackets 18 to move outward, increasing the distance between the two supporting brackets 18. Then insert one side of the sheet material between the supporting bracket 18 and the clamping plate 20 connected to the fixing rod 21. After keeping the sheet material horizontal, start the second hydraulic rod 17 to push the connected supporting bracket 18 towards the other side of the sheet material, using the two supporting brackets 18 to support the sheet material. Then rotate the threaded rod 19 to drive the clamping plate 20 to descend, clamping the sheet material with the clamping plate 20. Then start the second motor 23 to drive the screw rod 22 to rotate, so that the third slider 16 slides along the inner wall of the second support plate 4, thereby conveying the sheet material to the laser cutting assembly 5 for cutting. After cutting, start the first hydraulic rod 11 to drive the grinding wheel 10 to rise, using the grinding wheel 10 to grind the back of the sheet material. After cutting and grinding are completed, start the second motor 23 to drive the screw rod 22 to rotate in the reverse direction, so that the sheet material returns to the initial position. Then rotate the threaded rod 19 in the reverse direction to make the clamping plate 20 rise. Finally, take out the sheet material from the supporting bracket 18.

[0048] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of various changes or substitutions, and these should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
