[0036] Refer to Figures 1-6, the plate hole-opening device provided by the utility model includes a hole-opening mechanism, a transmission mechanism, and a support mechanism. The transmission mechanism includes a fixed base 2 and a movable base 3. The surfaces of the fixed base 2 and the movable base 3 are provided with placement grooves 4. The plate is placed on the placement groove 4 between the fixed base 2 and the movable base 3. The lower surface of the plate is attached to the inner bottom wall of the placement groove 4. The inner wall of the placement groove 4 is coated with wear-resistant paint to improve the wear resistance of the placement groove 4. The inner wall of the placement groove 4 is provided with equally spaced mounting grooves 5. A driving wheel 6 is rotatably connected to the inner wall of the mounting groove 5. The lower surfaces of the fixed base 2 and the movable base 3 are fixedly connected with a driving motor 15 that is in transmission connection with the driving wheel 6. The inner bottom wall of the placement groove 4 is provided with a weight-reducing groove 7, and the weight-reducing groove 7 reduces the weight of the fixed base 2 and the movable base 3. The support mechanism includes a support plate 8. The upper surface of one end of the support plate 8 is fixedly connected with the fixed base 2. A sliding groove 10 is provided on the upper surface of the support plate 8 away from the fixed base 2. A cylinder 9 is fixedly connected to the lower surface of the support plate 8. A connecting block 11 is slidably connected to the inner wall of the sliding groove 10. The lower surface of the movable base 3 is fixedly connected with the connecting block 11. The output end of the cylinder 9 is fixedly connected with the connecting block 11. Reinforcing ribs 12 are fixedly connected to both ends of the support plate 8. Place the plate on the placement groove 4 between the fixed base 2 and the movable base 3, and then start the cylinder 9 to make the cylinder 9 contract. The cylinder 9 drives the movable base 3 to move through the connecting block 11. Through the cooperation of the fixed base 2 and the movable base 3, the plate is clamped by the driving wheels 6 in the mounting grooves 5. Then start the driving motor 15 to drive the driving wheels 6 to rotate. When the plate is driven by the driving wheels 6 to move below the hole-opening mechanism, the driving motor 15 stops rotating, and the hole-opening mechanism punches the plate. Then, through the rotation of the driving wheels 6, the plate is conveyed out from the fixed base 2 and the movable base 3.

[0037] Support legs 13 are provided at the bottom of the support mechanism. The number of support legs 13 is six, and the support legs 13 are distributed in a rectangular array. The lower surfaces of the support legs 13 are fixedly connected with anti-slip bases 20, and the anti-slip bases 20 improve the anti-slip ability of the support legs 13. The hole-opening mechanism includes a fixing plate 1. A guiding frame 14 is fixedly connected to the upper surface of the fixing plate 1. An electric slider 16 is arranged inside the guiding frame 14. A hydraulic cylinder 17 is fixedly connected to the upper surface of the electric slider 16. The output end of the hydraulic cylinder 17 passes through the electric slider 16 and is fixedly connected with a lifting frame 18. A drilling machine 19 is fixedly connected to the inner wall of the lifting frame 18. The drill bit of the drilling machine 19 extends out of the bottom of the lifting frame 18 (this is a conventional means and is not described in detail in the specification drawings). The electric slider 16 moves left and right, thereby adjusting the position of the drilling machine 19, and further adjusting the position of the hole punching of the plate. The hydraulic cylinder 17 extends, thereby driving the lifting frame 18 to move downward, and further punching the plate through the drilling machine 19.

[0038] Working principle: Place the sheet on the placement groove 4 between the fixed base 2 and the moving base 3, and then start the cylinder 9 to make the cylinder 9 contract. The cylinder 9 drives the moving base 3 to move through the connecting block 11. Through the cooperation of the fixed base 2 and the moving base 3, the driving wheel 6 in the installation groove 5 clamps the sheet. Then start the driving motor 15 to drive the driving wheel 6 to rotate. When the sheet is driven by the driving wheel 6 to move below the punching mechanism, the driving motor 15 stops rotating, and the electric slider 16 moves left and right, so as to adjust the position of the punching machine 19, and further adjust the punching position of the sheet. The hydraulic cylinder 17 extends, and then drives the lifting frame 18 to move down, and then punches the sheet through the punching machine 19. Then, through the rotation of the driving wheel 6, the sheet is conveyed out of the fixed base 2 and the moving base 3.
