[0019] like Figure 1-5 As shown, a drilling device for sheet metal processing of shelving includes a support plate 1 with a notch 2 at one end and an anti-slip pad 3 on the bottom wall of the support plate 1. It also includes a limiting plate 4, a rotary motor 5, a pressing assembly 6, a blowing assembly 7, and a positioning mechanism 8. The limiting plate 4 is fixedly connected to the inner sidewall of the notch 2. The rotary motor 5 is movably connected above the notch 2 via the pressing assembly 6. A drill bit 9 is provided at the output end of the rotary motor 5, driving the drill bit 9 to penetrate the limiting plate 4 along the height direction of the notch 2 and act perpendicularly on the workpiece surface. The pressing assembly 6 is fixedly connected to the upper wall of the support plate 1 near the notch 2. The positioning mechanism 8 is movably connected to the end of the support plate 1 near the notch 2 and slides along the length direction of the support plate 1. The blowing assembly 7 is located on the upper wall of the support plate 1 away from the notch 2. A pressure chamber 10 is provided, and a through hole 11 is opened on the side wall of the pressure chamber 10 near the notch 2. Sliding holes 12 are opened on both sides inside the support plate 1. The sliding holes 12 are symmetrically distributed with the pressure chamber 10 and the notch 2 as the center. The bottom wall of the support plate 1 is attached to the plate, and the anti-slip pad 3 is used to increase the friction between the plate and the plate, so that the notch 2 side is away from the operator. With one end of the positioning mechanism 8 as the reference point, the support plate 1 is pulled, so that the positioning mechanism 8 is pulled out in the sliding hole 12 in the support plate 1. At the same time, the pulling distance is measured to realize the drilling position positioning. The rotary motor 5 and the drill bit 9 act vertically on the drilling surface of the plate through the pressing component 6 to perform the drilling operation. During the drilling process, the blowing component 7 pumps gas into the pressure chamber 10 and sprays it out through the through hole 11, so that the generated iron filings are blown out of the notch 2, which facilitates the observation of the hole position and the drilling situation.

[0020] like Figure 3-5As shown, in order to measure the hole spacing and locate the hole position, the positioning mechanism 8 includes a slide rod 20, a second support spring 21, a stop block 22, a horizontal plate 23, and a positioning plate 24. One end of the slide rod 20 passes through the support plate 1 near the notch 2 and is slidably disposed within the support plate 1. The horizontal plate 23 is fixedly connected to the other end of the symmetrical slide rod 20. The stop block 22 is fixedly connected to the end of the slide rod 20 away from the horizontal plate 23. The second support spring 21 is wound around the outer wall of the slide rod 20 and is located between the stop block 22 and the inner end face of the sliding hole 12. The positioning plate 24 is rotatably connected to the horizontal plate 23 away from the sliding hole 12. At the middle of one side wall of rod 20, the outer side wall of slide rod 20 is provided with scale line 25. Rotate positioning plate 24 to a vertical state, and with the inner side wall of positioning plate 24 as a reference, fit the hole or the side of the plate. Pull support plate 1 along the length of slide rod 20. Slide rod 20 and stop block 22 slide outward in sliding hole 12, while squeezing support spring 21 to increase the fit stability of positioning plate 24. Observe the scale line 25 on the outer side wall of slide rod 20. At the same time, the distance between drill bit 9 and the front end of notch 2 is a fixed value, realizing the distance detection between drill bit 9 and positioning plate 24.

[0021] like Figure 1 and Figure 3 As shown, in order to drill holes in the board, the pressing assembly 6 includes a support frame 13, a connecting rod 14, a support spring 15, a pressing plate 16, and a connecting plate 17. The support frame 13 is fixedly connected to the upper wall of the support plate 1 near the notch 2 and is located above the limiting plate 4. The connecting rod 14 slides through the upper wall of the support frame 13 and is slidably disposed inside the support frame 13. The connecting plate 17 is fixedly connected to the bottom end of the connecting rod 14, and the rotary motor 5 is fixedly connected to the bottom wall of the connecting plate 17. The pressing plate 16 is fixedly connected to the upper end of the connecting rod 14. The support spring 15 is wrapped around the outer wall of the connecting rod 14 and is located between the pressing plate 16 and the upper wall of the support frame 13. When the position of the drill bit 9 is adjusted, the pressing plate 16 is pressed down, the support spring 15 is compressed, the rotary motor 5 moves downward, and at the same time the drill bit 9 passes through the limiting plate 4 to drill holes in the board.

[0022] like Figure 4 and Figure 5 As shown, in order to make the drilling position clearly visible and reduce the accumulation of iron filings, the blowing assembly 7 includes an air pump 18. The air pump 18 is installed on the upper wall of the support plate 1 at the end away from the notch 2. The air outlet of the air pump 18 is connected to the pressure chamber 10. A rubber valve 19 is provided inside the through hole 11. The air pump 18 pumps the gas into the pressure chamber 10. After being pressurized by the rubber valve 19 inside the through hole 11, the gas is ejected and acts on the drilling position of the drill bit 9 to clean the drilling position, reduce the influence of iron filings on the drilling position, improve drilling efficiency, and facilitate the observation of the drilling situation.

[0023] In actual use, the operator can hold the side of the support frame 13 and move the device. In the initial state, the positioning plate 24 is close to the notch 2, and the drill bit 9 is blocked and limited by the limiting plate 4.

[0024] In use, rotate the positioning plate 24 to make it vertical. Using the inner wall of the positioning plate 24 as a reference, fit it against the hole or the side of the plate. Pull the support plate 1 along the length of the slide rod 20. After the support spring 21 is compressed, it increases the bonding stability of the positioning plate 24 through the reverse support force. Observe the scale line 25 and add the scale value to the fixed value from the drill bit 9 to the front end of the notch 2 to measure the distance between the drill bit 9 and the positioning plate 24.

[0025] After the position of drill bit 9 is adjusted, press down on the pressing plate 16 to compress the support spring 15, and rotate the motor 5 downward. At the same time, drill bit 9 passes through the limiting plate 4 to drill a hole in the plate. Simultaneously, air pump 18 pumps air into the pressure chamber 10, which is pressurized by the rubber valve 19 inside the through hole 11 and then ejected to the drilling point of drill bit 9 to clean the drilling position.
