Description

Technical Field

[0001] This utility model relates to the field of neodymium magnet processing technology, and more specifically, to a trimming mechanism for processing neodymium magnets. Background Technology

[0002] Neodymium magnets, also known as neodymium iron boron magnets, are tetragonal crystals formed from neodymium, iron, and boron (Nd2Fe14B). Neodymium iron boron is divided into two types: sintered neodymium iron boron and bonded neodymium iron boron. Bonded neodymium iron boron has magnetism in all directions and is corrosion resistant; while sintered neodymium iron boron is easily corroded and its surface needs to be plated, generally with zinc, nickel, environmentally friendly zinc, environmentally friendly nickel, nickel-copper-nickel, or environmentally friendly nickel-copper-nickel plating. During the production of neodymium magnets, edge trimming is often required.

[0003] A search revealed that patent application CN202023041207.3 discloses a trimming machine for neodymium magnet processing, comprising a base. Two identical first slide rails are mounted on the top two sides of the base. A first slider is slidably mounted on the first slide rails. A U-shaped trimming machine bracket is mounted on the end of the first slider away from the first slide rail. Rectangular second slide rails are respectively opened on the inner sides of the two branches of the trimming machine bracket. The second slider is slidably mounted on the second slide rails by bolts. A support plate is mounted on the second slider. A drive motor is mounted on the top of the support plate. The output end of the drive motor is rotatably connected to a driving wheel. The driving wheel is installed through and rotatably connected to a driven wheel. A transmission trimming structure is mounted on one end of the driven wheel. A waste collection box is installed directly below the transmission trimming structure, thus effectively keeping the entire workbench clean. The base has a fixing device on top to maintain the stability of the neodymium magnet during the trimming process, but the following defects still exist:

[0004] (1) In the prior art, when trimming neodymium magnets, manual fixing is required, which is inconvenient. At the same time, only the side edge of one side of the neodymium magnet can be trimmed. When trimming the side edge of different sides, the neodymium magnet needs to be re-fixed, which is cumbersome and results in low trimming efficiency.

[0005] (2) In the prior art, water is used to wash the waste residue left by trimming, which is inconvenient to recycle the trimming residue. In addition, the waste in the water is not easy to discharge, which is not very practical.

[0006] Therefore, we have made improvements to this by proposing a trimming mechanism for processing neodymium magnets. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, this embodiment proposes a trimming mechanism for processing neodymium magnets, including a housing 1, a collection box 2 slidably connected inside the housing 1, a support plate 3 located at the top of the housing 1, a tilting structure 4 for adjusting the tilt angle of the support plate 3 on the housing 1, a rotating clamping structure 5 on the support plate 3, a mounting frame 6 on the upper side of the housing 1, a shifting structure 7 for adjusting the position of the mounting frame 6, a first screw 8 rotatably connected inside the mounting frame 6, a first motor 9 fixedly connected to one end of the mounting frame 6, the drive end of the first motor 9 fixedly connected to the shaft end of the first screw 8, and a screw threaded onto the first screw 8. A movable block 10 is connected to the edge of the neodymium magnet. A support frame 11 is fixedly connected to the bottom of the movable block 10. A trimming motor 12 is fixedly connected inside the support frame 11. The drive end of the trimming motor 12 passes through the support frame 11 and is fixedly connected to a grinding disc 13. The collection box 2 facilitates the collection of trimming waste. The first screw 8 is driven to rotate by the first motor 9. The rotation of the first screw 8 causes the movable block 10 to move. The movement of the movable block 10 drives the support frame 11 to move, thereby adjusting the position of the grinding disc 13. The trimming motor 12 can drive the grinding disc 13 to rotate, thereby performing trimming processing on the neodymium magnet.

[0031] like Figure 1 and Figure 5 As shown, in a preferred embodiment, based on the above method, the tilting structure 4 further includes symmetrical support rods 401 fixed at both ends of the lower end face of the support plate 3. A rotating rod 402 is fixedly connected between the support rods 401. The two ends of the rotating rod 402 are rotatably connected to the left and right side walls of the housing 1, respectively. One end of the rotating rod 402 passes through the side wall of the housing 1 and is fixedly connected to a worm gear 403. A fixing plate 404 is fixedly connected to the side wall of the housing 1 near the worm gear 403. A second motor 405 is fixedly connected to the fixing plate 404. The drive end of the second motor 405 is fixedly connected to a worm 406 that meshes with the worm gear 403. The second motor 405 drives the worm 406 to rotate, and the worm 406 meshes with the worm gear 403, causing the rotating rod 402 and the support plate 3 to rotate around the axis of the rotating rod 402, thereby adjusting the tilt angle of the support plate 3, and thus being able to pour the trimming waste on the support plate 3 into the collection box 2.

[0032] like Figure 1 and Figure 6As shown, in a preferred embodiment, based on the above method, the rotary clamping structure 5 further includes two connecting plates 501 symmetrically fixed at both ends of the upper surface of the bearing plate 3. A bidirectional screw 502 is rotatably connected between the rear ends of the two connecting plates 501. A third motor 503 is fixedly connected to the outer wall of one of the connecting plates 501. The driving end of the third motor 503 is fixedly connected to one end of the shaft of the bidirectional screw 502. Two movable frames 504 are symmetrically and threadedly connected to the bidirectional screw 502. A rotating shaft 505 is rotatably connected to the top of each of the two movable frames 504. A clamping plate 506 is fixedly connected to the inner end of the rotating shaft 505, and a driven pulley 507 is fixedly connected to the outer end of the rotating shaft 505. By driving the bidirectional screw 502 to rotate through the third motor 503, the two movable frames 504 move towards or away from each other, adjusting the distance between the clamping plates 506 to clamp or release the neodymium magnet.

[0033] like Figure 1 and Figure 3 As shown, in a preferred embodiment, based on the above method, a bearing 508 is fixedly connected to the side wall of the movable frame 504 away from the bidirectional screw 502. A rotating tube 509 is fixedly connected to the inner side wall of the inner ring of the bearing 508. One end of the rotating tube 509 passes through the movable frame 504 and is flush with its side wall. A driving gear 5010 is fixedly connected to the other end of the rotating tube 509. A connecting shaft 5011 is rotatably connected to the movable frame 504. A driven gear 5012 that meshes with the driving gear 5010 is fixedly connected to the connecting shaft 5011. A driving pulley 5013 is fixedly connected to the outer end of the connecting shaft 5011. The driving pulley 5013 is connected to the driven pulley 507 through a synchronous belt 5014. A splined shaft 5015 is slidably connected inside the rotating tube 509. Both ends of the spline shaft 5015 are rotatably connected to the connecting plate 501. A fourth motor 5016 is fixedly connected to one of the connecting plates 501. The drive end of the fourth motor 5016 is fixedly connected to the shaft end of the spline shaft 5015. The fourth motor 5016 drives the spline shaft 5015 to rotate. The rotation of the spline shaft 5015 drives the rotating tube 509 and the driving gear 5010 to rotate. The rotation of the driving gear 5010 drives the driven gear 5012 and the connecting shaft 5011 to rotate. The rotation of the connecting shaft 5011 drives the driving pulley 5013 to rotate. The driving pulley 5013 drives the driven pulley 507 and the clamping plate 506 to rotate through the transmission of the synchronous belt 5014. This allows the neodymium magnet to be flipped, making it convenient to trim the sides of different faces of the neodymium magnet.

[0034] like Figure 1 and Figure 3As shown, in a preferred embodiment, based on the above method, the displacement structure 7 further includes two sets of fixing blocks 701 symmetrically fixed on the left and right side walls of the chassis 1. A second screw 702 is rotatably connected between one set of fixing blocks 701. A fifth motor 703 is fixedly connected to one of the fixing blocks 701, and the drive end of the fifth motor 703 is fixedly connected to the shaft end of the second screw 702. A displacement block 704 is threaded onto the second screw 702. A sliding rod 705 is fixedly connected between the other set of fixing blocks 701, and a slider 705 is slidably connected to the sliding rod 705. 6. A gantry frame 707 is fixedly connected between the shift block 704 and the slider 706. The upper end of the gantry frame 707 is symmetrical and fixedly connected to two telescopic cylinders 708. The drive ends of the two telescopic cylinders 708 pass through the gantry frame 707 and are fixedly connected to the mounting frame 6. This achieves precise positioning of the mounting frame 6 in three-dimensional space, which not only improves the flexibility of the trimming operation, but also ensures that the grinding disc 13 can accurately align with the neodymium magnet to be processed for trimming. At the same time, the addition of the telescopic cylinders 708 allows the height of the mounting frame 6 to be flexibly adjusted to meet the processing requirements of neodymium magnets of different sizes.

[0035] like Figure 6 As shown, in a preferred embodiment, based on the above method, a guide rod 14 is slidably connected inside the moving block 10, and the two ends of the guide rod 14 are fixedly connected to the left and right side walls of the mounting frame 6 respectively; this enhances the stability of the moving block 10 during movement, ensures the smooth operation of the grinding disc 13 during the trimming process, and improves the processing quality.

[0036] Specifically, the trimming mechanism for processing neodymium magnets operates as follows: the neodymium magnet to be processed is placed between two clamping plates 506. Then, the third motor 503 drives the bidirectional screw 502 to rotate, causing the two moving frames 504 to move inward simultaneously, thereby clamping the neodymium magnet between the clamping plates 506. Next, the fifth motor 703 drives the second screw 702 to rotate. The rotation of the second screw 702 moves the shifting block 704, thereby moving the gantry frame 707 and the grinding disc 13 to the appropriate position. Then, the telescopic cylinder 708 drives the mounting frame 6 to descend, bringing the grinding disc 13 into contact with the neodymium magnet. The trimming motor 12 drives the grinding disc 13 to rotate, which in turn drives the first screw 8 to rotate via the first motor 9. The rotation of the first screw 8 moves the moving block 10, which in turn moves the bearing frame 11, thereby moving the rotating grinding disc 13 and trimming the neodymium magnet. When trimming different surfaces, the grinding disc 13 is raised, and the fourth motor 5016 drives the spline shaft 5015 to rotate. The rotation of the spline shaft 5015 drives the rotating tube 509 and the drive gear 5010 to rotate. The rotation of the drive gear 5010 drives the driven gear 5012 and the connecting shaft 5011 to rotate. The rotation of the connecting shaft 5011 drives the drive pulley 5013 to rotate. The drive pulley 5013 drives the driven pulley 507 and the clamping plate 506 to rotate through the transmission of the synchronous belt 5014, thereby enabling the neodymium magnet to be flipped. Then, the neodymium magnet after flipping is trimmed. When it is necessary to dump the waste material on the support plate 3, the second motor 405 drives the worm gear 406 to rotate. The worm gear 406 meshes with the worm wheel 403, driving the rotating rod 402 and the support plate 3 to rotate around the axis of the rotating rod 402, thereby adjusting the tilt angle of the support plate 3, and thus being able to pour the trimming waste material on the support plate 3 into the collection box 2.

[0037] All technical features in this embodiment can be freely combined according to actual needs.

[0038] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
