[0002] Magnets have a wide range of applications in modern industry, and sometimes it is necessary to drill holes in magnets to meet the needs of certain applications. However, the current magnet drilling process has the following problems: During drilling, the high-speed friction between the magnet and the drill bit and the cutting force make it easy for magnet chips to fly everywhere. These flying chips may enter the operator's eyes or scratch the skin, posing a certain safety hazard. In addition, a large amount of chips accumulating around the processing equipment can interfere with the normal operation of the machine tool, damage the tool life, and affect the machining accuracy. Utility Model Content

Both the first through hole and the second through hole are smaller than the horizontal cross-sectional dimension of the magnet.

[0007] In the above technical solution, preferably, the magnetic attraction mechanism includes an upper magnetic ring and a lower magnetic ring. The upper magnetic ring is attached to the upper side of the first through hole, and the lower magnetic ring is close to the lower side of the second through hole.

Detailed Implementation

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0021] See Figures 1-5 This embodiment discloses a drilling device for magnet processing, including a frame 1 and a drilling mechanism 2, a conveying mechanism 3, and a magnetic attraction mechanism 4 disposed on the frame 1. The drilling mechanism 2 includes a driving mechanism 21 and a drill bit 22. The driving mechanism 21 drives the drill bit 22 to move up and down and rotate. The conveying mechanism 3 is used to convey magnets sequentially to the area below the drill bit 22. The magnetic attraction mechanism 4 is disposed below the drill bit 22 to attract magnet debris.

[0022] This invention uses a conveying mechanism 3 to sequentially transport magnets to the area below the drill bit 22. A driving mechanism 21 drives the drill bit 22 to rotate and move downwards to act on the magnets, thus realizing the drilling operation. At the same time, the magnetic attraction mechanism 4 below the drill bit 22 is close to the magnet being drilled and can attract and collect the debris that splashes during the drilling process, thereby reducing the probability of debris splashing into the surrounding environment, improving the safety of the magnet drilling process, and reducing the impact of debris on the service life of the equipment and the drilling accuracy.

[0023] See Figure 1 , Figure 2 The drive mechanism 21 includes a sliding frame 23, a lead screw motor 24, a drill bit holder 25, and a second motor 26. The sliding frame 23 is driven up and down to slide on the frame 1 by the lead screw motor 24. The drill bit holder 25 is driven to rotate on the sliding frame 23 by the second motor 26. The drill bit 22 is detachably fixed to the lower end of the drill bit holder 25.

[0024] The drill bit 22 moves up and down by driving the sliding frame 23 up and down via the lead screw motor 24, and the drill bit 22 rotates by driving the drill bit holder 25 via the second motor 26.

[0025] See Figure 2 , Figure 4 , Figure 5The conveying mechanism 3 includes a turntable 31 and a limiting plate 32. The turntable 31 is provided with a plurality of placement slots 33 that are adapted to the shape of the magnet at equal intervals around its circumference. The turntable 31 is driven to rotate on the frame 1 by a first motor 34. The limiting plate 32 is fixed on the frame 1 and is located above the turntable 31. The limiting plate 32 is provided with a first through hole 35 for the drill bit 22 to pass through. The bottom end of the placement slot 33 is provided with a second through hole 36 for the drill bit 22 to pass through. Both the first through hole 35 and the second through hole 36 are smaller than the horizontal cross-sectional dimension of the magnet.

[0026] By placing magnets one by one into each placement slot 33 and driving them with the first motor 34, the magnets are moved sequentially to the bottom of the drill bit 22. The magnetic drill bit 22, driven by the drive mechanism 21, passes through the first through hole 35 to drill a hole in the magnet. The second through hole 36 is used for the drill bit 22 to continue moving downward after drilling through the magnet to ensure that the magnet completes the drilling and improve the accuracy of the drilling position. The limiting plate 32 moves downward close to the upper surface of the magnet to limit the magnet and reduce the risk of the magnet falling out of the placement slot 33 due to the large stress it experiences during drilling.

[0027] See Figure 2 , Figure 3 The magnetic attraction mechanism 4 includes an upper magnetic ring 41 and a lower magnetic ring 42. The upper magnetic ring 41 is attached to the upper side of the first through hole 35, and the lower magnetic ring 42 is close to the lower side of the second through hole 36. The centers of the upper magnetic ring 41, the first through hole 35, the second through hole 36 and the lower magnetic ring 42 are located on the same vertical line.

[0028] When drill bit 22 drills a hole in the magnet, debris flies out in all directions. Therefore, by surrounding the drill hole with an upper magnetic ring 41, debris flying out from all angles can be attracted to the upper magnetic ring 41, reducing the probability of debris splashing into the surrounding environment. After drill bit 22 penetrates the magnet, some debris falls downwards from the drill hole. Therefore, by surrounding the magnet with a lower magnetic ring 42 below it, the falling debris can be attracted, increasing the debris attraction rate.

[0029] See Figure 2 , Figure 3 The magnetic attraction mechanism 4 also includes a sleeve 43, with the upper magnetic ring 41 and the lower magnetic ring 42 fixed on the sleeve 43. The sleeve 43 is horizontally rotatably mounted on the frame 1, and a collection groove 11 is provided on the rear side of the frame 1.

[0030] When the device has been working for a period of time, and the upper magnetic ring 41 and lower magnetic ring 42 have accumulated a lot of debris, resulting in a decrease in the adsorption effect of the upper magnetic ring 41 and lower magnetic ring 42, the upper magnetic ring 41 and lower magnetic ring 42 can be moved above the collection tank 11 by rotating the sleeve 43, so that the debris can be peeled off from the upper magnetic ring 41 and lower magnetic ring 42 and fall into the collection tank 11 for centralized processing.

[0031] See Figure 3 Both the upper magnetic ring 41 and the lower magnetic ring 42 are electromagnets.

[0032] Because the speed and amount of debris splashing during magnetic drilling vary depending on the processing conditions, the faster the drilling speed and the larger the diameter of the drill bit 22, the greater the splashing speed and amount of debris. Therefore, in this equipment, the magnetic force of the upper magnetic ring 41 and the lower magnetic ring 42 can be adjusted by regulating the current of the electromagnet according to the actual debris situation in production. This adapts to different processing conditions, ensuring that the upper magnetic ring 41 and the lower magnetic ring 42 can effectively attract debris while reducing energy consumption. When the electromagnet is de-energized, its magnetism disappears, facilitating the cleaning of debris from the upper magnetic ring 41 and the lower magnetic ring 42. De-energization allows some debris to automatically fall into the collection tank 11, while the remaining debris is cleaned manually. Compared to permanent magnets, using electromagnets improves debris cleaning efficiency.

[0033] See Figure 2 , Figure 4 The upper side of the limiting plate 32 is provided with a feeding container 37. Figure 1 (Not shown in the drawing), the feeding container 37 has a hollow structure with openings at both the top and bottom. The magnets are stacked inside the feeding container 37. The lower opening of the feeding container 37 passes through the limiting plate 32 and is located on the lower side of the limiting plate 32.

[0034] By stacking magnets in batches and placing them into the feeding container 37, the magnets fall downwards under the action of gravity. The magnet at the bottom enters the placement slot 33. The first motor 34 drives the turntable 31 to rotate and remove the bottom magnet. The magnets above fall downwards and continue to enter the next placement slot 33, thereby realizing the batch feeding of magnets and improving the convenience of feeding.

Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
