Description

Technical Field

[0001] This utility model relates to the technical field of magnet manufacturing, and in particular to a magnet grinding and positioning base. Background Technology

[0002] In modern industrial production, magnets, as important functional materials, are widely used in many fields such as new energy vehicles, wind power generation, and consumer electronics. Grinding is a crucial process in the production and processing of magnets, a key step in ensuring stable performance and reliable product quality. The positioning base in the grinding process, as an important auxiliary device, directly affects the processing quality and production efficiency of the magnets. Because magnets require multi-faceted grinding, positioning bases with flipping capabilities have emerged.

[0003] However, existing magnetic steel grinding positioning bases have the following shortcomings in practical use: After flipping, the positioning mechanism of existing positioning bases with flipping functions struggles to maintain the precise position of the magnet, leading to deviations in the magnet's position during grinding on different surfaces. This not only makes it difficult to guarantee the dimensional accuracy of the magnet, increasing the defect rate and production costs, but may also affect the magnetic distribution of the magnet due to uneven grinding, reducing product performance. Therefore, this application proposes a magnetic steel grinding positioning base. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a magnetic steel grinding positioning base that can maintain accurate positioning after the magnet is flipped, thereby improving grinding accuracy and product performance.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A magnetic steel grinding positioning base includes a housing and a grinding mechanism for grinding the surface of the magnetic steel. The grinding mechanism is disposed on the housing and further includes:

[0007] A support base is disposed on the housing and is located between the housing and the grinding mechanism;

[0008] The positioning assembly includes a flip frame, two sliders, two side blocks, two top supports, and several support members. A groove is formed on each of the two opposing inner sidewalls of the housing. The two sliders are slidably disposed within each groove. Both ends of the flip frame are respectively disposed on the sliders, and the two ends of the flip frame in the axial direction are perpendicular to the sides of the two sliders. One end of each of the two side blocks is fitted onto the two ends of the flip frame, and the other ends of the two side blocks are slidably disposed on the two opposing inner sidewalls of the housing. The support members... The supporting members are rotatably disposed on the upper and lower surfaces of the flip frame at intervals.

Two top holding members are slidably disposed on opposite sides of the flip frame, and the two top holding members clamp the magnet together. The two side blocks drive the flip frame to slide closer to the support base. The support base pushes the magnet up relative to the flip frame, so that the magnet is closer to the grinding mechanism.

[0009] The flipping assembly has a reversing groove that can change the sliding direction. The flipping assembly is disposed on the housing so that both ends of the reversing groove are connected to the slide groove. The flipping frame drives the slider to slide along the slide groove and through the reversing groove, so that the flipping frame drives the magnet to flip.

[0010] Optionally, the support base is disposed on the inner bottom wall of the housing, and the distance between the upper surface of the support base and the inner bottom wall of the housing is greater than the distance between the lower surface of each of the supporting members that jointly supports the magnet and the inner bottom wall of the housing.

[0011] Optionally, the edges of the upper surface of the support base are rounded.

[0012] Optionally, the support member includes an L-shaped block, a toothed ring, and a rack. The L-shaped block is rotatably mounted on the flip frame, and the toothed ring is coaxially mounted on the L-shaped block. The rack is slidably mounted on the flip frame, and one end of the rack extends from one end of the flip frame and slides against the side block. The rack meshes with the toothed ring so that the rack drives the L-shaped block to rotate relative to the flip frame.

[0013] Optionally, the flip frame is provided with a sliding tooth groove, the rack is slidably disposed in the sliding tooth groove, and the support member further includes a first elastic member, the first elastic member is located in the sliding tooth groove, and the first elastic member is used to push the rack to abut against the side block.

[0014] Optionally, the side block has a curved surface, and the end of the rack away from the first elastic member abuts against the curved surface.

[0015] Optionally, the top support includes a top plate, a sliding column, and a second elastic member. The flip frame is also provided with a top groove. One end of the sliding column is slidably disposed in the top groove. The top plate is disposed on the end of the sliding column away from the top groove. The second elastic member is located in the top groove. The second elastic member is used to push the sliding column to drive the top plate to press against the magnet.

[0016] Optionally, the flipping assembly includes an embedded block, a transformation component, and two pressure-sensitive components. The transformation component is rotatably mounted on the embedded block, and the two pressure-sensitive components are slidably mounted on the embedded block. The two pressure-sensitive components are located on opposite sides of the transformation component, and the ends of the two pressure-sensitive components away from the embedded block are rotatably connected to the transformation component. The reversing groove is formed on one side of the embedded block.

[0017] Optionally, the deflection groove includes a straight section and a curved section, and the embedded block is further provided with a straight plug hole and a curved plug hole, wherein the straight plug hole is connected to the straight section and the curved plug hole is connected to the curved section.

[0018] Optionally, the transformation component includes a balance bar, a straight block and a curved block. The two ends of the balance bar are rotatably connected to two pressure-sensitive components, and the two sides of the balance bar are rotatably connected to the straight block and the curved block, respectively.

[0019] Compared with the prior art, the present invention has at least the following advantages:

[0020] This utility model's magnetic steel grinding positioning base uses a slider to move the magnet directly onto a support base below the grinding mechanism. This allows the magnet to be stably supported, and the two top holding members of the flip frame can clamp the magnet, ensuring that the magnet is precisely positioned below the grinding mechanism for accurate grinding. Furthermore, this utility model's magnetic steel grinding positioning base is equipped with several flipping components. When the slider moves the magnet on the flip frame closer to the grinding structure, it can complete a full flip in one slide and return the flipping components to their initial state, facilitating the next flip and improving grinding efficiency.

Detailed Implementation

[0037] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model.

[0038] In the description of the embodiments of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings.

[0039] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0040] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0041] like Figures 1 to 13 As shown, in one embodiment, a magnetic steel grinding positioning base 1 includes a housing 10 and a grinding mechanism 20 for grinding the surface of a magnetic steel. The grinding mechanism 20 is disposed on the housing 10. It also includes a support base 30, a positioning component 40, and a flipping component 50. The support base 30 is disposed on the housing 10 and is located between the housing 10 and the grinding mechanism 20. The positioning component 40 includes a flipping frame 41, two sliders 42, two side blocks 43, two top supports 44, and several support members 45. A groove 121 is respectively opened on two opposing inner sidewalls of the housing 10. The two sliders 42 are slidably disposed in each groove 121. The two ends of the flipping frame 41 are respectively disposed on the sliders 42, and the two ends of the flipping frame 41 in the axial direction are perpendicular to the sides of the two sliders 42. One end of each of the two side blocks 43 is sleeved on the two ends of the flipping frame 41, and the other ends of the two side blocks 43 are slidably disposed on the... On the two opposing inner sidewalls of the housing 10, each support member 45 is rotatably disposed on the upper and lower surfaces of the flipping frame 41 at intervals. One end of each support member 45 on any surface of the flipping frame 41 abuts against two side blocks 43, so that the other end of each support member 45 extends into the flipping frame 41 to jointly support the magnet. Two top holding members 44 are slidably disposed on the opposing sides of the flipping frame 41, and the two top holding members 44 clamp the magnet together. The two side blocks 43 drive the flipping frame 41 to slide close to the support seat 30. The support seat 30 pushes the magnet relative to the flipping frame 41, so that the magnet is close to the grinding mechanism 20. The flipping assembly 50 is provided with a direction-changing groove that can change the sliding direction. The flipping assembly 50 is disposed on the housing 10 so that both ends of the direction-changing groove are connected to the slide groove 121. The flipping frame 41 drives the slider 42 to slide along the slide groove 121 through the direction-changing groove, so that the flipping frame 41 drives the magnet to flip.

[0042] It should be noted that the housing 10 includes a base plate 11 and two surrounding plates 12. The two surrounding plates 12 are located on opposite sides of the base plate 11 to form a frame-like structure. Slide grooves 121 are respectively formed on the two surrounding plates 12. Two grinding mechanisms 20 are provided, with a gap between them. The two ends of the two grinding mechanisms 20 are located on the end faces of the two surrounding plates 12 away from the base plate 11, so that the center position of the grinding mechanism 20 is located between the two surrounding plates 12. Further, support seats 30 are provided on the base plate 11, and there is a gap between the two support seats 30. The two support seats 30 are respectively located below the two grinding mechanisms 20. Further, the flip frame 41 has a square structure, for example, a rectangular frame structure. A square hole is provided on the flip frame 41 for accommodating magnets. Two top supports 44 are slidably disposed on the two inner sidewalls of the short side of the square hole. Each support member 45 is rotatably disposed on the upper and lower surfaces of the flip frame 41 at intervals. One end of each support member 45 protrudes relative to the upper and lower surfaces of the flip frame 41, and the other end of each support member 45 slides against the two side blocks 43. For example, when one end of each support member 45 on the lower surface of the flip frame 41 slides against the two side blocks 43, the end of each support member 45 away from the two side blocks 43 rotates toward the square hole, so that the end of the square hole near the lower surface of the flip frame 41 forms multiple fulcrums for supporting the magnet. Each support member 45 supports the magnet together, allowing the magnet to be placed inside the flip frame 41.

[0043] It should be noted that when the positioning component 40 drives the magnet to slide along the slide groove 121 to the support base 30, the distance between the upper surface of the support base 30 and the base plate 11 is greater than the distance between the lower surface of the magnet supported by each support member 45 and the base plate 11. Furthermore, the upper surface of the support base 30 near the grinding component is a flat plane, and the two corners of the upper surface of the support base 30 perpendicular to the opening direction of the slide groove 121 are rounded. This allows the lower surface of the magnet to be lifted upwards along the rounded corners and slide onto the upper surface of the support base 30 when the positioning component 40 drives the magnet to approach the support base 30. When the positioning component 40 drives the magnet to slide below the grinding component, the magnet can be stably placed on the support base 30. Furthermore, the width of the support base 30 is less than the interval between the two top support members 44, allowing the two top support members 44 to hold the two ends of the pushing magnet in place when the magnet is on the support base 30. In this way, when the grinding structure grinds the upper surface of the magnet, it can prevent the magnet from shaking, which would result in poor grinding quality.

[0044] like Figures 1 to 5 As shown, in one embodiment, the positioning component 40 includes a flip frame 41, two sliders 42, two side blocks 43, two top supports 44, and several support members 45.

[0045] It should be noted that each end of the flip frame 41 is provided with a pivot 411, and two sliders 42 are respectively disposed on the two pivots 411. Further, two sliding grooves 121 are respectively opened on the opposite side surfaces of the two enclosure plates 12, extending from one end of the enclosure plate 12 to the other end, and both sliding grooves 121 are located below the two grinding mechanisms 20. Further, the two sliders 42 slide within the two sliding grooves 121, so that the two sliders 42 together drive the flip frame 41 to slide closer to or away from the grinding mechanism 20 along the opening direction of the sliding groove 121. Further, each enclosure plate 12 is also provided with a side groove 122, the opening direction of the side groove 122 is consistent with the opening direction of the sliding groove 121, and the side groove 122 is located below the sliding groove 121. Furthermore, one end of each of the two side blocks 43 is slidably disposed within the two side grooves 122, and the other end of each of the two side blocks 43 is respectively sleeved on the two rotating shafts 411 at both ends of the flip frame 41. Furthermore, each of the two side blocks 43 is provided with a connecting hole 431, which is used to connect a power device. For example, the output end of a push cylinder is screwed into the connecting hole 431, so that the push cylinder can drive the side block 43 to slide along the direction of the side groove 122, so that the side block 43 drives the flip frame 41 to slide closer to or away from the grinding mechanism 20 via the rotating shaft 411.

[0046] It should be noted that the slider 42 tends to be a waist-shaped block structure. The pivots 411 on both ends of the flip frame 41 are respectively connected to one end of the two sliders 42, and the sliders 42 are parallel to the flip frame 41. Thus, when the slider 42 is located in the slide groove 121, the flip frame 41 is in a horizontal state.

[0047] like Figures 1 to 3 , Figure 5 , Figures 7 to 8 As shown, in one embodiment, the support member 45 includes an L-shaped block 451, a toothed ring 452, and a rack 453. The L-shaped block 451 is rotatably mounted on the flip frame 41, and the toothed ring 452 is coaxially mounted on the L-shaped block 451. The rack 453 is slidably mounted on the flip frame 41, and one end of the rack 453 extends from one end of the flip frame 41 and slides against the side block 43. The rack 453 meshes with the toothed ring 452 so that the rack 453 drives the L-shaped block 451 to rotate relative to the flip frame 41.

[0048] It should be noted that several circular grooves 412 are provided on both the upper and lower surfaces of the flip frame 41. One end of each L-shaped block 451 is rotatably disposed in a corresponding circular groove 412, such that the other end of each L-shaped block 451 protrudes relative to the upper and lower surfaces of the flip frame 41. Furthermore, a sliding tooth groove 413 is provided on the flip frame 41. One end of the sliding tooth groove 413 is connected to the side of the flip frame 41 near the rotating shaft 411, and the other end of the sliding tooth groove 413 is connected to the circular groove 412. The toothed ring 452 is fitted onto the end of the L-shaped block 451 near the flip frame 41. The toothed ring 452 is also located in the circular groove 412, and the toothed ring 452 meshes with the rack 453 in the sliding tooth groove 413. Thus, when the rack 453 slides out or into the sliding tooth groove 413 from one end of the flip frame 41, the rack 453 will drive the L-shaped block 451 to rotate through the toothed ring 452, thereby causing the end of the L-shaped block 451 away from the circular groove 412 to rotate toward the center of the square hole or rotate away from the center of the square hole.

[0049] It should be noted that the support member 45 also includes a first elastic member 454, which is located in the sliding tooth groove 413. The two ends of the first elastic member 454 abut against the inner bottom wall of the sliding tooth groove 413 and the end of the rack 453, respectively, so that the first elastic member 454 pushes the rack 453 to extend from the side of the flip frame 41 near the rotating shaft 411, thereby causing the rack 453 to drive the L-shaped block 451 away from the circular groove 412 to rotate away from the center position of the flip frame 41 through the toothed ring 452.

[0050] like Figures 1 to 4 , Figure 6 As shown, in one embodiment, the side block 43 has a curved surface, and the end of the rack 453 away from the first elastic member 454 abuts against the curved surface.

[0051] It should be noted that a shaft hole 434 is provided on the side block 43, penetrating the two opposing sides of the side block 43, so that the side block 43 can be fitted onto the rotating shaft 411. Furthermore, a curved surface is formed on the side surface of the side block 43 near the flip frame 41, and the two ends of the curved surface are divided into an upper part 432 and a lower part 433 with the diameter of the shaft hole 434 as the boundary and the opening direction of the slide groove 121 as the parallel direction. The upper part 432 of the curved surface makes the thickness of the upper end of the side block 43 gradually decrease, thereby increasing the distance between the surface of the upper part 432 and the end face of the flip frame 41. The lower part 433 of the curved surface makes the thickness of the lower end of the side block 43 gradually remain unchanged, thereby making the surface of the lower part 433 fit against the end face of the flip frame 41. Furthermore, when the side block 43 is fitted onto the rotating shaft 411, the upper and lower surfaces of the flip frame 41 are located at the upper part 432 and the lower part 433 of the curved surface, respectively. For example, the upper surface of the flip frame 41 is located at the upper part 432 of the curved surface, and the lower surface of the flip frame 41 is located at the lower part 433 of the curved surface. Furthermore, one end of each rack 453 extends from the end of the flip frame 41 near the side block 43, such that one end of each rack 453 on the upper surface slides against the upper part 432, and one end of each rack 453 on the lower surface slides against the lower part 433. Thus, when the flipping frame 41 rotates around the axis of the shaft hole 434, when either the upper or lower surface of the flipping frame 41 abuts against the lower part 433, the lower part 433 extends the pushing rack 453 into the sliding tooth groove 413, thereby causing the rack 453 to drive the L-shaped block 451 away from the circular groove 412 to rotate towards the inside of the square hole through the toothed ring 452, so as to jointly support the magnet. Meanwhile, the racks 453 on the other surface will extend out of the sliding tooth groove 413 under the pushing of the first elastic member 454, thereby causing the L-shaped block 451 away from the circular groove 412 to rotate away from the square hole, so that the magnet can be inserted into the square hole from top to bottom.

[0052] like Figures 1 to 3 , Figure 5 , Figures 7 to 8 As shown, in one embodiment, the top support 44 includes a top plate 441, a sliding column 442, and a second elastic member 443. The flip frame 41 is also provided with a top groove 444. One end of the sliding column 442 is slidably disposed in the top groove 444. The top plate 441 is disposed on the end of the sliding column 442 away from the top groove 444. The second elastic member 443 is located in the top groove 444. The second elastic member 443 is used to push the sliding column 442 to drive the top plate 441 to press the magnet tightly.

[0053] It should be noted that top grooves 444 are respectively formed on the two inner sidewalls of the short side of the square hole. One end of the sliding column 442 is set on one side surface of the top plate 441, and the other end of the sliding column 442 slides in the top groove 444. The second elastic member 443 is located in the top groove 444. One end of the second elastic member 443 abuts against the inner bottom wall of the top groove 444, and the other end of the second elastic member 443 pushes the end of the sliding column 442 away from the top plate 441. In this way, the top plates 441 on the two supporting members 44 move closer to each other under the push of the two second elastic members 443 to clamp the magnet together. Both the first elastic member 454 and the second elastic member 443 are spring structures.

[0054] like Figures 1 to 2 , Figures 8 to 13 As shown, in one embodiment, the flipping assembly 50 includes an embedded block 51, a changer 53, and two pressure-sensitive components. A reversing groove is formed on one side of the embedded block 51. The changer 53 is rotatably mounted on the embedded block 51. The two pressure-sensitive components are slidably mounted on the embedded block 51, and the two pressure-sensitive components are located on both sides of the changer 53. The ends of the two pressure-sensitive components away from the embedded block 51 are rotatably connected to the changer 53.

[0055] It should be noted that the embedded block 51 is disposed on two opposing enclosure plates 12 of the housing 10, and the deflection groove is opened on one side of the embedded block 51. The two ends of the deflection groove are respectively connected to the two ends of the embedded block 51, so that when the embedded block 51 is disposed on the enclosure plate 12, both ends of the deflection groove are connected to the sliding groove 121, so that the deflection groove and the sliding groove 121 are merged into one groove.

[0056] It should be noted that the deflection groove includes a straight section 510 and a curved section 511, with both ends of the straight section 510 connected to both ends of the curved section 511. The embedded block 51 also has a straight plug hole 520 and a curved plug hole 521, both of which penetrate the two opposing sides of the embedded block 51. The straight plug hole 520 is connected to the straight section 510, and the curved plug hole 521 is connected to the curved section 511. Furthermore, the transformation member 53 is rotatably disposed on the back side of the embedded block 51, with one side of the transformation member 53 extending into the curved plug hole 521 and the other side of the transformation member 53 extending into the straight plug hole 520. When the transformation member 53 rotates relative to the embedded block 51 to create a height difference between the two sides of the transformation member 53, one side of the transformation member 53 extends into the straight plug hole 520 / curved plug hole 521, while the other side of the transformation member 53 moves away from the straight plug hole 520 / curved plug hole 521. When the transformation member 53 reciprocates relative to the embedded block 51, the two sides of the transformation member 53 alternately extend into the straight plug hole 520 / curved plug hole 521.

[0057] like Figure 1 , Figures 11 to 12As shown, in one embodiment, the changer 53 includes a balance bar 530, a straight block 531, and a curved block 532. The two ends of the balance bar 530 are rotatably connected to two pressure-sensitive elements, and the two sides of the balance bar 530 are rotatably connected to the straight block 531 and the curved block 532, respectively. The end of the straight block 531 away from the balance bar 530 slides in the straight block hole 520, and the end of the curved block 532 away from the balance bar 530 slides in the curved block hole 521.

[0058] It should be noted that the balance bar 530 is rotatably mounted on the embedded block 51. One end of the straight plug 531 slides within the straight plug hole 520, and the other end of the straight plug 531 is rotatably connected to one side of the balance bar 530. One end of the curved plug 532 slides within the curved plug hole 521, and the other end of the curved plug 532 is rotatably connected to the side of the balance bar 530 away from the straight plug 531. Thus, when the balance bar 530 reciprocates relative to the embedded block 51, it causes the balance bar 530 to alternately extend the straight plug 531 and the curved plug 532 into the straight plug hole 520 / curved plug hole 521, respectively. Specifically, when the balance bar 530 drives the straight block 531 along the straight block hole 520 into the straight section 510 to block the connection between the straight section 510 and the slide groove 121, the balance bar 530 simultaneously drives the curved block 532 along the curved block hole 521 away from the curved section 511, so that both ends of the curved section 511 are connected to the slide groove 121. When the balance bar 530 drives the straight block 531 along the straight block hole 520 away from the straight section 510 to connect the straight section 510 and the slide groove 121, the balance bar 530 simultaneously drives the curved block 532 along the curved block hole 521 into the curved section 511 to block the connection between the curved section 511 and the slide groove 121. In this way, rotating the balance bar 530 achieves alternating connection between the straight section 510 / curved section 511 and the slide groove 121.

[0059] It should be noted that both pressure-sensitive elements are inserted into the embedded block 51, with one end of each element extending from the inner bottom wall of the slide groove 121, and the other end rotatably connected to both ends of the balance bar 530. Specifically, the two pressure-sensitive elements are rotatably connected to the two sides of the end of the balance bar 530. For ease of description, the two pressure-sensitive elements are defined as a first pressure-sensitive element 541 and a second pressure-sensitive element 542. The first pressure-sensitive element 541 is located on the side of the balance bar 530 closer to the straight block 531. The second pressure-sensitive element 542 is located on the side of the balance bar 530 closer to the curved block 532. Furthermore, the ends of both pressure-sensitive elements furthest from the balance bar 530 extend from the inner bottom wall of the slide groove 121, and the two pressure-sensitive elements are located on opposite sides of the deflection groove. Furthermore, an arc-shaped portion 420 is provided on the side of the slider 42 away from the rotating shaft 411. When the slider 42 slides in the groove 121, the arc-shaped portion 420 slides and abuts against the end of any pressure-sensitive element away from the balance bar 530. This causes the slider 42 to push a pressure-sensitive element out from the end of the straight plug hole 520 / curved plug hole 521 near the balance bar 530, thereby driving the balance bar 530 to rotate. The rotation of the balance bar 530 will cause any one of the straight section 510 / curved section 511 to connect with the groove 121.

[0060] like Figure 3 , Figure 5 , Figure 8 As shown, in one embodiment, a guide post 421 is provided on the slider 42. The guide post 421 is located on the end of the slider 42 away from the rotating shaft 411. A guide groove 1210 is provided on the inner bottom wall of the slide groove 121. Both the straight section 510 and the curved section 511 are connected to the guide groove 1210.

[0061] It should be noted that there are two grinding mechanisms 20 and two flipping components 50. The two flipping components 50 are alternately arranged with the two grinding mechanisms 20, and the two flipping components 50 are arranged in opposite directions. Both flipping components 50 are located on a surrounding plate 12. This allows the magnet to advance past one flipping component 50 after grinding one surface, causing the other surface to flip upwards and fit against the other grinding mechanism 20 for grinding.

[0062] It should be noted that both polishing mechanisms 20 and both flipping components 50 are located near one end of the housing 10. For ease of description, the two polishing mechanisms 20 and the two flipping components 50 are defined as the first polishing mechanism, the second polishing mechanism, the first flipping component, and the second flipping component, respectively, and are distributed at intervals starting from one end of the housing 10. For example, they are distributed in the following order: first polishing mechanism, first flipping component, second polishing mechanism, and second flipping component. The first polishing mechanism is located near one end of the housing 10, while the starting position of the flipping frame 41 is located at the end of the housing 10 away from the first polishing mechanism. Furthermore, the initial state of slider 42 is with guide post 421 close to the side of the second flip assembly. Thus, when slider 42 slides along the groove 121 towards the second flip assembly, the arc-shaped portion 420 on slider 42 will first press the first pressure-sensitive element 541 on the second flip assembly. The first pressure-sensitive element 541 on the second flip assembly will open the straight section 510 and close the curved section 511 via the balance bar 530, making the straight section 510 and guide groove 1210 connected in a straight line. When slider 42... When the slider 42 slides through the straight section 510, the arc-shaped part 420 on the slider 42 will press the second pressure-sensitive element 542 on the second flip assembly. The second pressure-sensitive element 542 on the second flip assembly will open the curved section 511 and close the straight section 510 through the balance bar 530, and reset the initial state of the first pressure-sensitive element 541 on the second flip assembly. At this time, the slider 42 drives the guide post 421 to slide straight along the guide groove 1210 to the position of the second grinding mechanism to grind one upper surface of the magnet.

[0063] It should be noted that when the slider 42 drives the flip frame 41 to slide from the second grinding mechanism towards the first flip assembly, the arc-shaped part 420 on the slider 42 first presses the second pressure-sensitive element 542 on the first flip assembly. The second pressure-sensitive element 542 on the first flip assembly will open the curved section 511 and close the straight section 510 through the balance bar 530. At this time, the guide post 421 on the slider 42 enters the curved section 511 from the guide groove 1210. Since both ends of the slider 42 are connected to the guide post 421 and the rotating shaft 411 respectively, when the guide post 421 slides upward along the curved section 511... This causes the slider 42 to rotate around the pivot 411. When the guide post 421 slides to the highest point of the curved section 511, the slider 42 causes the flip frame 41 to slide perpendicularly to the sliding direction of the groove 121. Since the side block 43 is fitted on the pivot 411, the side block 43 pushes the pivot 411 to continue to drive the slider 42 to slide along the groove 121. This causes the pivot 411 to drive the guide post 421 to slide out from the other end of the curved section 511 through the slider 42. In this way, the front and rear positions of the guide post 421 and the pivot 411 are reversed, which causes the slider 42 to drive the flip frame 41 to flip. When slider 42 drives guide post 421 to slide out of curved section 511, the arc-shaped part 420 on slider 42 presses the first pressure-sensitive element 541 on the first flip assembly. The first pressure-sensitive element 541 on the first flip assembly closes curved section 511 and opens straight section 510 via balance bar 530, and resets the second pressure-sensitive element 542 on the first flip assembly. At this time, slider 42 drives flip frame 41 to complete the flip, so that the unpolished surface of magnet is flipped to an upward state to enter the first polishing mechanism for polishing.

[0064] It should be noted that after the upper and lower surfaces of the magnet are polished, the slider 42 will drive the guide post 421 to slide across the straight section 510 on the first flip assembly and press the second pressure-sensitive element 542 on the first flip assembly to close the straight section 510 on the first flip assembly and open the curved section 511, and reset the first pressure-sensitive element 541 on the first flip assembly, so that the first flip assembly is reset to the initial state. When slider 42 drives flip frame 41 back to the second flip assembly, the arc-shaped portion 420 on slider 42 first presses the second pressure-sensitive element 542 on the second flip assembly to open the curved section 511 and close the straight section 510, and resets the first pressure-sensitive element 541. The guide post 421 on slider 42 slides into the curved section 511, and one end of the rotating shaft 411 on slider 42 drives the guide post 421 to slide out from the other end of the curved section 511 to complete the flip. Slider 42 then presses the first pressure-sensitive element 541 on the second flip assembly to close the curved section 511 and open the straight section 510, and resets the second pressure-sensitive element 542, so that the guide post 421 and rotating shaft 411 on slider 42 return to their initial state. Furthermore, when side block 43 pushes rotating shaft 411 to drive slider 42 to slide from one end of housing 10 to the other end, it can slide and flip on the two grinding mechanisms 20 to grind the upper and lower surfaces of the magnet. In this way, the magnetic steel grinding positioning base 1 of this application can achieve grinding on both sides of the magnetic steel with one sliding back and forth, thereby improving grinding efficiency.
