[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Example 1:

[0023] like Figure 1 As shown, a laser cutting device for automotive metal structural parts includes a base 1. A processing box 2 is fixedly installed on the top of the front end of the base 1. A strip-shaped opening 9 is opened on the top of the processing box 2. A fixed plate 7 is movably connected to the top of the processing box 2. A rubber plug is provided at the bottom of the fixed plate 7. A limit frame 12 is fixedly installed on the inner wall of the processing box 2. A filter plate 10 is movably engaged on the inner wall of the limit frame 12. Two sets of rotating shafts 14 are rotatably connected to the inner wall of the limit frame 12. Two sets of symmetrical movable plates 13 are fixedly installed on the outer surface of the two sets of rotating shafts 14. A strip rod 8 is rotatably connected to the top of one set of the two sets of movable plates 13. The strip rod 8 is movably connected to the processing box 2. A pull ring 4 is fixedly connected to the front end of the strip rod 8. Two sets of striking mechanisms 11 are rotatably connected to the inner wall of the processing box 2.

[0024] By creating a slot 9 at the top of the treatment chamber 2, with the length of the slot 9 being equal to the length of the filter plate 10, the filter plate 10 can flexibly enter and exit the treatment chamber 2. Furthermore, by providing a fixing plate 7, when the filter plate 10 is installed inside the treatment chamber 2, the fixing plate 7 can use its bottom rubber plug to seal the slot 9, preventing external dust from falling onto the filter plate 10 and affecting the filtration effect. When it is necessary to replace the filter plate 10, the fixing plate 7 can be removed, releasing the seal on the slot 9. Then, press down on the two sets of pull rings 4. The strip rod 8 is movably connected to the treatment box 2, so that when the pull ring 4 is pressed down, the strip rod 8 slides down. The strip rod 8 then presses down the front end of the movable plate 13 connected to it. The rotating shaft 14 rotates under the drive of the movable plate 13, thereby causing the other set of movable plates 13 to tilt up, thereby achieving the purpose of lifting the filter plate 10, so that the front end of the filter plate 10 extends out from the strip opening 9, so that the damaged filter plate 10 can be taken out for replacement, ensuring the filtration effect.

[0025] like Figure 1 and Figure 2 As shown, a laser cutting device for automotive metal structural parts includes a base 1 with a support frame 16 fixedly mounted on the top. A drive motor 15 is fixedly mounted on one side of the support frame 16. A threaded rod 17 is rotatably connected to the inner wall of the base 1, and the output end of the drive motor 15 is fixedly connected to the front end of the threaded rod 17, providing power for the rotation of the threaded rod 17. A slider 18 is slidably engaged with the top wall of the base 1, and the inner wall of the slider 18 is threadedly connected to the outer surface of the threaded rod 17. When the drive motor 15 is energized, its output end drives the threaded rod 17 to rotate. The slider 18 slides along the top wall of the support frame 16 under the action of the threaded engagement. A second hydraulic rod 22 is fixedly installed at the bottom of the slider 18. As the slider 18 slides, it drives the second hydraulic rod 22 to move. A support plate 21 is fixedly installed at the front end of the second hydraulic rod 22, and a laser head is provided at the bottom of the support plate 21. When the slider 18 moves above the automotive structural component, it controls the operation of the second hydraulic rod 22. The second hydraulic rod 22 will then drive the laser head at the bottom of the support plate 21 to approach the structural component, thereby performing laser cutting on the structural component.

[0026] like Figure 1-5As shown, a laser cutting device for automotive metal structural parts includes an operating table 19 fixedly installed on the bottom wall of a base 1. Two sets of symmetrical first hydraulic rods 20 are fixedly installed on the top of the operating table 19. After placing the structural part on the operating table 19, controlling the operation of the first hydraulic rods 20 causes them to drive the front plate to clamp the structural part, preventing displacement during cutting. A dust suction head 23 is fixedly installed at the bottom of a support plate 21, and the dust suction head 23 is connected to a processing box 2 via a gooseneck tube. The dust suction head 23 is located on one side of the laser head and is used to remove the dust generated during cutting. Smoke and dust are sucked away; a fan 5 is fixedly installed on the inner wall of the treatment box 2. The fan 5 rotates to exhaust the air in the treatment box 2, thereby causing the suction head 23 to suck in air. A collection box 6 is fixedly installed at the bottom of the front end of the base 1, and the top end of the collection box 6 is connected to the bottom end of the tail end of the treatment box 2. A dust collection box 3 is movably connected to the inner wall of the collection box 6. The sucked-up dust leaks into the dust collection box 3 due to the action of the filter plate 10 and the impact mechanism 11, so as to facilitate centralized discharge. The filter plate 10 can filter toxic gases, and the filtered gas is discharged from the air outlet where the fan 5 is located through the filter plate 10.

[0027] It should be noted that this utility model is a laser cutting device for automotive metal structural parts. During use, the structural part to be cut is placed on the operating table 19, and the first hydraulic rod 20 is controlled to clamp and fix the structural part to prevent it from shifting during the cutting process. The drive motor 15 is energized, and with the cooperation of the threaded rod 17 and the slider 18, the laser head moves to a suitable position to begin cutting. During the cutting process, the fan 5 is activated, which in turn causes the dust suction head 23 to suck away the dust generated during cutting and deliver it to the processing box 2 through a hose. The particles fall into the dust collection box 3 under the influence of the filter plate 10 and the impact mechanism 11. The filtered gas is discharged from the air outlet of the fan 5. When the filter plate 10 needs to be replaced, open the fixing plate 7, and then press down on the two sets of pull rings 4 to make the strip rod 8 slide down and squeeze the front end of the movable plate 13 connected to it. Under the action of the rotating shaft 14, the other set of movable plates 13 is tilted upward, pushing the filter plate 10 upward, so that the front end of the filter plate 10 extends out of the strip opening 9 for easy removal and replacement, ensuring the filtration effect of the device and protecting the surrounding environment.
