Description

Technical Field

[0001] This utility model belongs to the technical field of positioning and processing, and in particular relates to a positioning device for the processing of neodymium iron boron magnets. Background Technology

[0002] Neodymium iron boron (NdFeB) magnets are high-performance permanent magnets. Based on the required magnet performance, the proportions of neodymium, iron, boron, and other trace elements are precisely calculated and proportioned. The NdFeB alloy is then smelted under high temperature and vacuum conditions to obtain the magnet. The sintered magnet is then subjected to machining processes such as cutting, grinding, and drilling to achieve the final dimensional and shape accuracy. Strict control of dimensional tolerances and shape accuracy is required during the machining process.

[0003] In the common processing of neodymium iron boron (NdFeB) magnets, the magnets need to be cut, and then the cut magnets need to be ground to a specific position. In actual use, the NdFeB magnets need to be clamped and restrained before grinding. However, while restraining the position, the part of the clamping device in contact with the NdFeB magnet cannot be ground. Therefore, we provide a positioning device for the NdFeB magnet processing to solve the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this invention is to provide a positioning device for the processing of neodymium iron boron magnets. Through the specific structural design of the processing support component and the positioning adjustment component, the problems in the background art mentioned above are solved.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a positioning device for the processing of neodymium iron boron magnets, including a processing support assembly. The processing support assembly includes a hollow support platform. Two lifting guide rails are symmetrically fixedly connected to the upper surface of the hollow support platform. A lifting support plate is slidably arranged between the two lifting guide rails. A grinding disc is rotatably connected to the lower surface of the lifting support plate, and two guide slides are symmetrically opened on the upper surface of the hollow support platform. Two positioning adjustment assemblies are symmetrically slidably arranged on the upper surface of the lifting support plate. The positioning adjustment assembly includes a positioning support plate. A transmission block that slides and cooperates with the corresponding guide slide is fixedly connected to the lower surface of the positioning support plate. Two L-shaped positioning connecting rods are symmetrically rotatably arranged on one side of the positioning support plate. Positioning transmission wheels are rotatably connected to both ends of the L-shaped positioning connecting rods.

[0006] The present invention is further configured such that: an adjusting gear is rotatably connected to the top of the hollow support platform; an adjusting bevel gear is fixedly connected to the lower surface of the adjusting gear; a drive shaft is rotatably arranged between the two inner sidewalls of the hollow support platform; a transmission bevel gear is fixedly connected to the circumferential side of the drive shaft; the transmission bevel gear and the adjusting bevel gear mesh with each other; a transmission gear is fixedly connected to the circumferential side of the drive shaft; a drive gear is rotatably connected to one inner sidewall of the hollow support platform; the drive gear and the transmission gear mesh with each other; a drive motor is fixedly installed on one side of the hollow support platform; and the output shaft of the drive motor is fixedly connected to the drive gear.

[0007] The present invention is further configured such that: driving bevel gears are rotatably provided on both sides of the hollow support platform; the two driving bevel gears are fixedly connected to both ends of the drive shaft; lifting bevel gears are symmetrically rotatably provided on the lower surface of the hollow support platform; the lifting bevel gears mesh with the corresponding driving bevel gears; a driving screw is rotatably connected between the lifting guide rail and the two inner sidewalls; the driving screw is fixedly connected to the corresponding lifting bevel gear; and the driving screw is threadedly engaged with the lifting support plate.

[0008] The present invention is further configured such that two ear plates are symmetrically fixedly connected to one side of the positioning support plate near the L-shaped positioning link, the L-shaped positioning link is rotatably connected to the ear plates, an extension support plate is fixedly connected to the upper surface of the L-shaped positioning link, and an arc-shaped return spring is fixedly connected between the extension support plate and the positioning support plate; a transmission rack is fixedly connected to one side of the transmission block, the adjusting gear is located between the two transmission racks, and the transmission rack and the adjusting gear mesh with each other.

[0009] This utility model has the following beneficial effects: 1. By setting a positioning adjustment component, this utility model controls the two positioning support plates to move synchronously and approach each other, driving the L-shaped positioning link to move synchronously. When one positioning transmission wheel on the L-shaped positioning link contacts the corresponding side of the neodymium iron boron magnet, as the positioning support plate continues to move, the L-shaped positioning link rotates until the other positioning transmission wheel contacts the corresponding side of the neodymium iron boron magnet, thus limiting the position of the corner of the neodymium iron boron magnet. The L-shaped positioning links cooperate with each other to limit the position of the four corners of the neodymium iron boron magnet, preventing the neodymium iron boron magnet from shifting during processing, and preventing the positioning adjustment component from hindering the grinding operation while limiting the position, so as to make the grinding effect consistent.

[0010] 2. This utility model, by setting up a processing support component and a positioning adjustment component, drives the bevel gear to rotate synchronously during the synchronous movement of the two positioning support plates. This drives the lifting bevel gear to rotate, which in turn drives the drive screw to rotate. With the threaded engagement between the drive screw and the lifting support plate, the lifting support plate moves up and down synchronously, thereby driving the grinding disc to move up and down. This achieves both limiting and adjusting the position and height of the grinding disc, thus improving processing efficiency.

[0011] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0022] Please see Figure 1-5 This utility model is a positioning device for the processing of neodymium iron boron magnets, including a processing support component 1. Specifically, the processing support component 1 includes a hollow support platform 101. Two lifting guide rails 102 are symmetrically fixedly connected to the upper surface of the hollow support platform 101. A lifting support plate 103 is slidably arranged between the two lifting guide rails 102. A grinding disc 104 is rotatably connected to the lower surface of the lifting support plate 103. The lower surface of the grinding disc 104 is made of a rough material. A grinding motor is fixedly connected to the upper surface of the lifting support plate 103. The output shaft of the grinding motor is fixedly connected to the grinding disc 104. Two guide slides 105 are symmetrically opened on the upper surface of the hollow support platform 101. The guide slides 105 are connected to the interior of the hollow support platform 101.

[0023] Furthermore, two positioning adjustment components 2 are symmetrically slidably arranged on the upper surface of the lifting support plate 103. The positioning adjustment component 2 includes a positioning support plate 201. A transmission block that slides and cooperates with the corresponding guide slide 105 is fixedly connected to the lower surface of the positioning support plate 201. Two L-shaped positioning connecting rods 202 are symmetrically rotatably arranged on one side of the positioning support plate 201. Both ends of the L-shaped positioning connecting rods 202 are rotatably connected to positioning transmission wheels 203.

[0024] The operation process of this embodiment is as follows: The cut neodymium iron boron magnet is placed between the L-shaped positioning rods 202. The two positioning support plates 201 are controlled to slide synchronously towards each other along the corresponding guide rails 105. During this process, the lifting support plate 103 slides synchronously downwards along the two lifting guide rails 102, causing the grinding disc 104 to move synchronously downwards. When the positioning transmission wheel 203 at one end of the L-shaped positioning rod 202 on the positioning support plate 201 contacts the corresponding side of the neodymium iron boron magnet, as the positioning support plate 201 continues to move, the end of the L-shaped positioning rod 202 in contact with the neodymium iron boron magnet is obstructed, and the L-shaped positioning rod 202 rotates until the positioning transmission wheel 203 at the other end of the L-shaped positioning rod 202... 3. The grinding disc 104 contacts the corresponding side of the neodymium iron boron magnet and pushes the neodymium iron boron magnet to move. With the cooperation of the L-shaped positioning rods 202 on the two positioning support plates 201, the four corners of the neodymium iron boron magnet are restricted. During this process, the grinding disc 104 continues to move downward. When the position of the neodymium iron boron magnet is restricted, the grinding disc 104 is in contact with the upper surface of the neodymium iron boron magnet. The grinding motor is started, which drives the grinding disc 104 to rotate and grind the upper surface of the neodymium iron boron magnet. After the processing is completed, the two positioning support plates 201 are controlled to move in opposite directions in a synchronous manner and move away from each other. The restriction on the neodymium iron boron magnet is removed. At the same time, the grinding disc 104 moves upward and away from the neodymium iron boron magnet. The neodymium iron boron magnet is flipped over and the operation is repeated to grind the other side. Specific Implementation Example 2

[0026] Please see Figure 1-5 Based on the specific embodiment one, specifically, an adjusting gear 106 is rotatably connected to the top of the hollow support platform 101, and an adjusting bevel gear 107 is fixedly connected to the lower surface of the adjusting gear 106. A drive shaft is rotatably arranged between the hollow support platform 101 and the two inner side walls. A transmission bevel gear 108 is fixedly connected to the circumferential side of the drive shaft, and the transmission bevel gear 108 and the adjusting bevel gear 107 mesh with each other.

[0027] Furthermore, a transmission gear 109 is fixedly connected to the circumferential side of the drive shaft, and a drive gear 110 is rotatably connected to the inner side wall of the hollow support platform 101. The drive gear 110 and the transmission gear 109 mesh with each other. A drive motor is fixedly installed on one side of the hollow support platform 101, and the output shaft of the drive motor is fixedly connected to the drive gear 110.

[0028] Furthermore, the hollow support platform 101 is rotatably provided with driving bevel gears 111 on both sides, and the two driving bevel gears 111 are fixedly connected to the two ends of the drive shaft respectively. The lower surface of the hollow support platform 101 is symmetrically provided with lifting bevel gears 112, and the lifting bevel gears 112 mesh with the corresponding driving bevel gears 111.

[0029] Furthermore, a drive screw 113 is rotatably connected between the lifting guide rail 102 and the two inner side walls. The drive screw 113 is fixedly connected to the corresponding lifting bevel gear 112, and the drive screw 113 is threadedly engaged with the lifting support plate 103.

[0030] Furthermore, two ear plates are symmetrically fixedly connected to one side of the positioning support plate 201 near the L-shaped positioning link 202. The L-shaped positioning link 202 is rotatably connected to the ear plates. An extension support plate is fixedly connected to the upper surface of the L-shaped positioning link 202. An arc-shaped return spring 204 is fixedly connected between the extension support plate and the positioning support plate 201. A transmission rack 205 is fixedly connected to one side of the transmission block. An adjusting gear 106 is located between the two transmission racks 205, and the transmission racks 205 and the adjusting gear 106 mesh with each other.

[0031] The operation process of this embodiment is as follows: The cut neodymium iron boron magnet is placed on the upper surface of the hollow support platform 101, with the magnet positioned between the L-shaped positioning rods 202. The drive motor is started, driving the drive gear 110 to rotate. Under the meshing action of the drive gear 110 and the transmission gear 109, the transmission gear 109 rotates, thereby driving the drive shaft to rotate. The transmission bevel gear 108 rotates synchronously with the drive shaft. Under the meshing action of the transmission bevel gear 108 and the adjusting bevel gear 107, the adjusting bevel gear 107 rotates, driving the adjusting gear 106 to rotate. Under the meshing action of the adjusting gear 106 and the two transmission racks 205, the two transmission racks 205 move synchronously, thereby driving the transmission block along the corresponding guide slide. 105 moves internally, and the positioning support plate 201 moves synchronously with the transmission block and approaches each other. When the positioning transmission wheel 203 at one end of the L-shaped positioning link 202 on the positioning support plate 201 contacts the corresponding side of the neodymium iron boron magnet, as the positioning support plate 201 continues to move, the L-shaped positioning link 202 at the end of the positioning transmission wheel 203 in contact with the neodymium iron boron magnet is obstructed, the L-shaped positioning link 202 rotates, and the arc-shaped return spring 204 is stretched until the positioning transmission wheel 203 at the other end of the L-shaped positioning link 202 contacts the corresponding side of the neodymium iron boron magnet and pushes the neodymium iron boron magnet to move. Under the cooperative action of the L-shaped positioning links 202 on the two positioning support plates 201, the four corners of the neodymium iron boron magnet are restricted.

[0032] As the drive shaft rotates and the two positioning support plates 201 approach each other, the two drive bevel gears 111 rotate synchronously with the drive shaft. Under the meshing action of the drive bevel gears 111 and the lifting bevel gears 112, the lifting bevel gears 112 rotate, thereby driving the drive screw 113 to rotate. Under the threaded engagement of the drive screw 113 and the lifting support plate 103, the lifting support plate 103 slides downward along the two lifting guide rails 102. When the grinding disc 104 moves downward synchronously with the lifting support plate 103, and the position of the neodymium iron boron magnet is limited... The grinding disc 104 is in contact with the upper surface of the neodymium iron boron magnet. The grinding motor is started, which drives the grinding disc 104 to rotate and grind the upper surface of the neodymium iron boron magnet. After grinding one side of the neodymium iron boron magnet is completed, the drive motor drives the drive gear 110 to rotate in the opposite direction, and the drive shaft rotates in the opposite direction synchronously. Then, the two positioning support plates 201 move in the opposite direction synchronously and move away from each other. The restriction of the neodymium iron boron magnet is removed. At the same time, the grinding disc 104 moves upward and away from the neodymium iron boron magnet. The neodymium iron boron magnet is flipped over and the operation is repeated to grind the other side.
