The driving component 34 is fixedly installed on one side of the adjustment frame 311. The output end of the driving component 34 is transmission-connected with the center of the No. 1 gear 312. The No. 1 gear 312 is transmission-connected with the No. 1 rack 313. One side of the adjustment frame 311 is slidably connected with a mounting plate 31 4. One end of the mounting plate 314 is fixedly connected to another set of driving components 34. The output end of the other set of driving components 34 is drivingly connected with a No. 2 gear 315.

The output end of the stepper motor 322 is transmission-connected to another No. 2 mounting frame 321, the other end of the other No. 2 mounting frame 321 is fixedly connected to another stepper motor 322, one side of the laser cutting head 33 is transmission-connected to another stepper motor 322, the two ends of one side of the adjustment frame 311 are fixedly connected to the No. 2 slide rail 317, the outer sides of the two No. 2 slide rails 317 are slidingly clamped with the No. 2 slide 318, the No. 2 slide 318 is fixedly mounted on one end of one side of the mounting plate 314, and the drive assembly 34 includes a No. 2 drive motor 341 and a gearbox 342.

[0027] In this embodiment, when it is necessary to cut various complex shapes on the alloy plate, the two sets of stepper motors 322 cooperate with each other to adjust the laser cutting head 33 at multiple angles, so that the laser beam can flexibly change direction. For example, when cutting alloy components with curves, slopes or internal holes, the laser beam angle can be adjusted in real time according to the change in shape to achieve precise tracking cutting, thereby allowing the laser cutting device used to manufacture pressure instrument panels to cut complex shapes on alloy plates.

[0028] The use method and working principle of the device are as follows: Before laser cutting, several preheating components 15 in the cutting base 12 preheat the alloy plate, and the driving rods in the two groups of cylinders 152 lift the No. 1 mounting frame 153, so that the preheating plate 154 on one side of the No. 1 mounting frame 153 contacts the alloy plate, and the preheating plate 154 is powered on to generate heat to heat the alloy plate. When the temperature of the alloy plate rises to the specified temperature, the No. 1 mounting frame 153 and the preheating plate 154 located directly below the cutting processing area descend and stop preheating, and the laser cutting mechanism 3 cuts the alloy plate in the cutting area. The laser cutting mechanism 3 is used to cut the alloy sheet, while the remaining preheating components 15 continue to preheat the alloy sheet at a constant temperature; the driving component 34 in the laser cutting mechanism 3 drives the adjusting frame 311 to adjust the single-axis cutting position, and another set of driving components 34 on the mounting plate 314 drives the mounting plate 314 to move downward, so that the laser cutting head 33 is close to the alloy sheet for laser cutting. When the laser cutting mechanism 3 completes the laser cutting of the cutting area, the driving component 34 in the feeding component 11 drives the third gear 112 to rotate. Since the third gear 112 and the third rack 113 are meshed with each other, The mounting table 111 is driven to slide on the sliding frame 1, thereby driving the cutting base 12 to feed in the direction of the laser cutting mechanism 3, so that the alloy plate to be cut moves to the bottom of the laser cutting mechanism 3. At this time, the electric clamp 165 releases the positioning clamp of the alloy plate, and the No. 1 driving motor 161 drives the screw rod 162 to rotate. The driving block 163 slides on the screw rod 162, driving the driving table 164 and the electric clamp 165 to move away from the laser cutting mechanism 3 until they move to the area to be cut. The electric clamp 165 positions and clamps the alloy plate again; when it is necessary to cut various complex shapes on the alloy plate, the two sets of stepper motors 322 cooperate with each other to adjust to complete the multi-angle rotation adjustment of the laser cutting head 33.
