[0040] Example 3: Based on Examples 1 and 2, specifically as follows... Figure 1 As shown, a drilling machine includes the positioning and clamping structure described in any of the above embodiments and a drilling machine 43. A servo motor 44 is fixedly mounted on the top of the drilling machine 43, and one end of a first connecting plate 42 is fixedly connected to one side outer wall of the drilling machine 43. Starting the servo motor 44 drives the drilling machine 43 to start drilling holes in the material.

[0041] In summary, the structure of the drilling machine 43 and the servo motor 44 achieves the purpose of drilling the sheet metal, improving the processing efficiency of the sheet metal, enhancing the ease of use of the device, and optimizing the user experience.

[0042] Working principle: Place the sheet material on top of the feeding plate 17, rotate the two sets of knobs, causing the threaded rod 33 to rotate inside the threaded sleeve 32. Since the threaded rod 33 and the threaded sleeve 32 are spirally connected, and the threaded sleeve 32 can rotate inside the second limiting plate 29, under the guidance of the guide plate 34, it will drive the second limiting plate 29 to move. As the second limiting plate 29 moves, the distance between the two sets of second clamping plates 30 is adjusted. The protective pads 31 at the bottom of the two sets of second clamping plates 30 will press the top of the sheet material, and at the same time, the second clamping plates 30 will clamp the sides of the sheet material, completing the positioning and clamping of the sheet material in the lateral direction. Pulling the first limiting plate 2... 0. The first movable rod 19 moves inside the feeding plate 17, causing the bottom of the first clamping plate 22 to be tightly against the top of the plate. Under the elastic force of the damping spring rod 21, the inner wall of the first limiting plate 20 will be tightly against the side of the plate, thereby positioning and clamping the plate in another direction. Through the cooperation of the first positioning part and the second positioning part, the plate is positioned and clamped in all directions. The first electrical control box 13 is activated to control the movement of the first electric push rod 14. The telescopic inner rod of the first electric push rod 14 pushes the first slider 16 to slide inside the first slide groove 12. The first slider 16 drives the first connecting block 15 to move. Since the first connecting block 15 and the feeding plate 17 is fixedly connected, thereby adjusting the position of the feeding plate 17 to adjust the position of the plate to meet the needs of different drilling positions. The debris generated during drilling falls into the debris collection box 23 through the first perforated slot plate 18 inside the feeding plate 17. The second perforated slot plate 24 inside the debris collection box 23 helps to further collect the debris. The dust curtains 25 on the four inner walls of the debris collection box 23 can prevent debris from splashing out of the debris collection box 23. The suction pump 28 is started. Under the action of the suction pump 28, the debris is collected from inside the debris collection box 23 to inside the cleaning box 27 through the conveying pipe 26, which facilitates the subsequent cleaning of the debris. The hydraulic cylinder 40 is activated, and its output end drives the hydraulic push rod 41 to move. The hydraulic push rod 41 pushes the lifting plate 38 to move inside the support plate 35. The lifting plate 38 drives the second slider 37 to slide inside the second slide groove 36. At the same time, the lifting plate 38 moves on the guide rod 39, which plays a guiding role, thereby adjusting the height of the first connecting plate 42. Since the first connecting plate 42 is fixedly connected to the drilling machine 43, the height of the drilling machine 43 is adjusted so that the drilling machine 43 reaches the appropriate drilling position. The servo motor 44 is activated, and the servo motor 44 drives the drilling machine 43 to start and perform drilling operations on the positioned and clamped plate.
