Technical Field
[0001] This utility model belongs to the field of neodymium iron boron processing technology, specifically, it relates to a neodymium iron boron multi-face grinding device. Background Technology
[0002] Neodymium iron boron (NdFeB) permanent magnets are based on the intermetallic compound Nd2Fe14B. NdFeB possesses extremely high magnetic energy product and coercivity, along with high energy density. It has been widely used in modern industry and electronics. The manufacturing process of NdFeB permanent magnets utilizes powder metallurgy, with the following steps: raw material preparation → smelting and ingot forming → powder preparation → molding → sintering and tempering → magnetic testing → grinding → cutting → electroplating → finished product.
[0003] A document with publication number (CN222609082U) discloses a multi-faceted grinding device for processing neodymium iron boron magnets. The device includes a worktable with a transmission mechanism on it. The transmission mechanism is equipped with a feeding mechanism, a first grinding mechanism, a flipping mechanism, a second grinding mechanism, a drying mechanism, and a discharging mechanism. The feeding mechanism transports the neodymium iron boron magnets onto the transmission mechanism. The first grinding mechanism grinds both sides of the neodymium iron boron magnets on the transmission mechanism. The flipping mechanism flips the ground neodymium iron boron magnets 90 degrees. The second grinding mechanism grinds both sides of the flipped neodymium iron boron magnets. The drying mechanism dries the ground neodymium iron boron magnets. The discharging mechanism removes the dried neodymium iron boron magnets from the transmission mechanism. This device achieves fully automated processing from raw material feeding to finished product unloading, significantly improving production efficiency and ensuring product consistency and quality stability.
[0004] The aforementioned device uses a flipping mechanism to flip the NdFeB magnet and then grind the other surfaces. However, the flipping mechanism increases the travel distance of the NdFeB magnet, prolongs the processing time, and affects the processing efficiency of the NdFeB magnet.

Detailed Implementation
[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.
[0027] Please see Figure 1-5A multi-faceted grinding device for neodymium iron boron (NdFeB) magnets includes a grinding assembly mounted on a mounting frame 1. The grinding assembly is used for multi-faceted grinding of NdFeB magnets. The grinding assembly includes the mounting frame 1, a fixing frame 4, and first cleaning blocks 41. The fixing frame 4 is connected to the wall of the mounting frame 1 by fasteners, including but not limited to bolts. The first cleaning blocks 41 are arranged around the fixing frame 4, and corresponding first cleaning blocks 41 are elastically connected to the fixing frame 4. NdFeB magnets abut between the first cleaning blocks 41. The first cleaning blocks 41 are arranged longitudinally and laterally... The cleaning blocks 41 are staggered, and the longitudinal and transverse staggered arrangement of the first cleaning block 41 achieves full enclosure of the wall surface of the NdFeB, realizing all-round grinding of the wall surface and full-range grinding. The first cleaning block 41 grinds the columnar NdFeB. The first cleaning block 41 and the second cleaning block 5 eliminate the need to flip the NdFeB. NdFeB includes columnar NdFeB and rectangular NdFeB. Multi-face grinding is directly achieved during transportation, shortening the processing path of NdFeB, shortening the processing time, and improving processing efficiency.
[0028] In a preferred embodiment of this utility model, a support plate 42 is arranged around the fixed frame 4. Each support plate 42 is fixedly connected to the fixed frame 4. A second slide rod 43 is slidably connected to each support plate 42. Each second slide rod 43 is connected to a corresponding first cleaning block 41 by fasteners, including but not limited to bolts. A second spring 44 is sleeved on each second slide rod 43. The end of each second spring 44 is fixedly connected to the corresponding first cleaning block 41 and the support plate 42. The end of each second slide rod 43 is also connected to a second cleaning block 5 by fasteners. The second slide rod 43 is arranged longitudinally and laterally. The cleaning blocks 5 are staggered, with each first cleaning block 41 arranged in an arc shape and each second cleaning block 5 arranged in a straight line. After the neodymium iron boron is transported between the first cleaning blocks 41, the first cleaning block 41 drives the second slide rod 43 to move and compress the second spring 44. The second spring 44 deforms and applies the deformation force to the first cleaning block 41, making the first cleaning block 41 in close contact with the wall surface of the neodymium iron boron. Through the staggered arrangement of the first cleaning blocks 41 in the longitudinal and transverse directions, the wall surface of the neodymium iron boron is fully surrounded, achieving all-round grinding of the wall surface and full-range grinding. The columnar neodymium iron boron is ground by the first cleaning blocks 41.
[0029] When the rectangular NdFeB needs to be polished, the first cleaning block 41 on the second slide bar 43 is replaced with the second cleaning block 5. Through the straight line setting of the second cleaning block 5, it makes close contact with the rectangular NdFeB, so as to achieve full polishing of the rectangular NdFeB.
[0030] The first cleaning block 41 and the second cleaning block 5 eliminate the need to flip the NdFeB, which includes columnar NdFeB and rectangular NdFeB. Multi-face grinding can be directly achieved during transportation, shortening the processing path of NdFeB, reducing processing time, and improving processing efficiency.
[0031] The mounting frame 1 has a mounting block 2 fixedly connected to one end, and multiple conveying rollers 21 are rotatably connected to the mounting block 2. The conveying rollers 21 are driven by a motor and a transmission belt. The other end of the mounting frame 1 has a guide block 6 fixedly connected to it. The guide block 6 has an inclined surface. The multiple conveying rollers 21 are driven to rotate by the cooperation between the motor and the transmission belt. During the rotation, the NdFeB is transported to the device for processing. The processed NdFeB is discharged outward through the inclined surface of the guide block 6.
[0032] The mounting frame 1 is symmetrically equipped with fixing blocks 3, each fixing block 3 being fixedly connected to the mounting frame 1. Each fixing block 3 is slidably connected to a first sliding rod 31, each first sliding rod 31 is fixedly connected to a connecting block 33, and each connecting block 33 is fixedly connected to a connecting rod 34. Connecting frames 35 are fixedly connected between corresponding connecting rods 34. Each connecting frame 35 is rotatably connected to an abutment wheel 36, each abutting wheel 36 abutting against a neodymium iron boron magnet. Each first sliding rod 31 is fitted with a first spring 32. The ends of the spring 32 are fixedly connected to the corresponding fixing block 3 and connecting block 33 respectively. After the abutting wheel 36 contacts the wall surface of the neodymium iron boron, the abutting wheel 36 drives the connecting block 33, connecting rod 34 and connecting frame 35 to move and compress the first sliding rod 31. After the first sliding rod 31 is compressed, it deforms and applies the deformation force in the opposite direction to the abutting wheel 36, making the abutting wheel 36 in close contact with the wall surface of the neodymium iron boron. In the transportation of neodymium iron boron in this device, the abutting wheels 36 on both sides rotate and clamp, limiting the neodymium iron boron and preventing the transportation of neodymium iron boron from being deviated.
[0033] Working principle: Multiple conveyor rollers 21 are driven to rotate by the cooperation between the motor and the transmission belt, transporting neodymium iron boron (NdFeB) to the device for processing. The processed NdFeB is discharged outwards through the inclined surface of the guide block 6. After the abutment wheel 36 contacts the wall of the NdFeB, it drives the connecting block 33, connecting rod 34, and connecting frame 35 to move and compress the first slide rod 31. The first slide rod 31 deforms under compression and applies the deformation force in the opposite direction to the abutment wheel 36, ensuring close contact between the abutment wheel 36 and the wall of the NdFeB. During the transport of NdFeB in this device, the rotating clamping of the abutment wheels 36 on both sides limits the NdFeB and prevents deviation during transport. After the NdFeB is transported between the first cleaning blocks 41, the first cleaning blocks 41 drive the second slide rod 43 to move and compress the second spring 44. 4. Deformation is generated and the force of deformation is applied to the first cleaning block 41, bringing the first cleaning block 41 into close contact with the wall surface of the NdFeB. Through the longitudinal and transverse staggered arrangement of the first cleaning block 41, the wall surface of the NdFeB is fully surrounded, achieving all-round grinding of the wall surface and full-range grinding. The first cleaning block 41 is used to grind columnar NdFeB. When rectangular NdFeB needs to be ground, the first cleaning block 41 on the second slide bar 43 is replaced with the second cleaning block 5. Through the straight arrangement of the second cleaning block 5, it makes close contact with the rectangular NdFeB, achieving full grinding of the rectangular NdFeB. The first cleaning block 41 and the second cleaning block 5 eliminate the need to flip the NdFeB. NdFeB includes columnar NdFeB and rectangular NdFeB. Multi-face grinding is directly achieved during transportation, shortening the processing path of NdFeB, shortening the processing time, and improving processing efficiency.
