[0021] Beneficial effects of the utility model:

[0022] The utility model provides a multi-polar magnetic ring magnetizing device, which includes a positioning mechanism, and the positioning mechanism includes a first support plate, a rotating plate, a fixed plate and a plurality of positioning magnetizing structures. Among them, the rotating plate is connected to the first support plate by rotating around its own central axis.

[0050] The multi-pole magnetic ring is a ring-shaped magnet widely used in the field of motors. Using a multi-pole magnetic ring in a motor can effectively reduce the number of components of the motor, effectively reduce the assembly difficulty of the motor, and effectively improve the working reliability of the motor. Among them, the multi-pole magnetic ring magnetization device is used to magnetize the multi-pole magnetic ring.

[0051] At present, a multi-pole magnetic ring magnetization device in the prior art mainly consists of an upper horizontal plate, a lower horizontal plate, a cylinder, a magnetization fixture, a positioning magnetic strip, etc. The cylinder drives the upper horizontal plate and the lower horizontal plate to clamp the multi-pole magnetic ring. The multi-pole magnetic ring is positioned by attracting it with the positioning magnetic strip, and the multi-pole magnetic ring is clamped by the magnetization fixture, so that the multi-pole magnetic ring can be discharged and magnetized. However, the positioning magnetic strip is a single magnetic strip, and the positioning accuracy when positioning the multi-pole magnetic ring is poor, and the magnetic field of the positioning magnetic strip itself will affect the magnetization direction of the magnetization pole head of the magnetization coil, resulting in inaccurate magnetization direction.

[0052] Therefore, the present utility model provides a multi-pole magnetic ring magnetization device. Among them, Figure 1 is the front view of the multi-pole magnetic ring magnetization device provided in this embodiment. Figure 2 is the top view of the multi-pole magnetic ring magnetization device provided in this embodiment. Figure 3 is the cross-sectional view of the multi-pole magnetic ring magnetization device provided in this embodiment. Figure 4 is the first partial structural schematic diagram of the positioning mechanism 1 of the multi-pole magnetic ring magnetization device provided in this embodiment. Figure 5 is the second partial structural schematic diagram of the positioning mechanism 1 of the multi-pole magnetic ring magnetization device provided in this embodiment. Figure 6It is a schematic structural diagram of the positioning and magnetizing structure 14 of the multi-pole magnetic ring magnetizing device provided in this embodiment. Figure 7 It is a partial structural schematic diagram three of the positioning mechanism 1 of the multi-pole magnetic ring magnetizing device provided in this embodiment.

[0053] As Figures 1 - 7 shown, the multi-pole magnetic ring magnetizing device includes a positioning mechanism 1, and the positioning mechanism 1 includes a first support plate 13, a rotating plate 11, a fixing plate 12, and a plurality of positioning and magnetizing structures 14. Among them, the rotating plate 11 is rotatably connected to the first support plate 13 around its own central axis. The fixing plate 12 is fixedly connected to the first support plate 13 and stacked on the rotating plate 11. The plurality of positioning and magnetizing structures 14 are spaced apart and are all slidably connected to the fixing plate 12. The positioning and magnetizing structure 14 can magnetize the multi-pole magnetic ring. The rotating plate 11 is configured to drive the plurality of positioning and magnetizing structures 14 to synchronously approach or move away from each other when rotating around its own central axis. When the plurality of positioning and magnetizing structures 14 approach each other, the multi-pole magnetic ring can be clamped between the plurality of positioning and magnetizing structures 14 and supported on the fixing plate 12 or the rotating plate 11.

[0054] When magnetizing the multi-pole magnetic ring by this multi-pole magnetic ring magnetizing device, first support the multi-pole magnetic ring on the fixing plate 12 or the rotating plate 11, so that the multi-pole magnetic ring is located between the plurality of positioning and magnetizing structures 14 and does not contact the plurality of positioning and magnetizing structures 14. Then drive the rotating plate 11 to rotate around its own central axis to drive the plurality of positioning and magnetizing structures 14 to synchronously approach each other, so that the plurality of positioning and magnetizing structures 14 all approach the multi-pole magnetic ring. Then synchronously apply the same low-frequency current to the plurality of positioning and magnetizing structures 14. Under the action of the low-frequency current, the magnetic fields of the plurality of positioning and magnetizing structures 14 drive the multi-pole magnetic ring to rotate around its own central axis, so that the multiple magnetic poles of the multi-pole magnetic ring correspond one by one to the distribution positions of the plurality of positioning and magnetizing structures 14, and the multi-pole magnetic ring is rotated to the optimal magnetizing state. Then continue to drive the rotating plate 11 to rotate around its own central axis so that the rotating plate 11 drives the plurality of positioning and magnetizing structures 14 to synchronously approach each other until the multi-pole magnetic ring is clamped between the plurality of positioning and magnetizing components 141. It can be understood that at this time, the setting position of the multi-pole magnetic ring is completely fixed. Then discharge and magnetize the multi-pole magnetic ring synchronously through the plurality of positioning and magnetizing structures 14.

[0055] When the magnetizing of the multi-pole magnetic ring is completed, drive the rotating plate 11 to rotate around its own central axis to drive the plurality of positioning and magnetizing structures 14 to synchronously move away from each other, so that the plurality of positioning and magnetizing structures 14 all move away from the multi-pole magnetic ring, and the magnetized multi-pole magnetic ring can be detached, and the next multi-pole magnetic ring can be magnetized.

[0056] Thus, on the basis of effectively discharging and magnetizing the multi-pole magnetic ring, the multiple positioning and magnetizing structures 14 of the multi-pole magnetic ring magnetizing device can accurately rotate the multi-pole magnetic ring to the optimal magnetizing state, so that the multiple magnetic poles of the multi-pole magnetic ring precisely correspond to the magnetizing directions of the multi-pole positioning and magnetizing structures 14 one by one, thereby enabling accurate magnetization of each magnetic pole of the multi-pole magnetic ring. The working performance of the multi-pole magnetic ring magnetizing device is effectively improved.

[0057] In this embodiment, the multi-pole magnetic ring is a circular magnet. In other embodiments, the multi-pole magnetic ring can also be a square magnetic ring or a rectangular magnetic ring, etc. It can be understood that the positioning mechanism 1 can also be used to position other workpieces that do not require magnetization.

[0058] In this embodiment, it can be understood that the number of the multiple positioning and magnetizing structures 14 is an even number.

[0059] In this embodiment, as Figure 4 and Figure 5 shown, the number of the positioning and magnetizing structures 14 is exemplarily set to four. In other embodiments, the number of the positioning and magnetizing structures 14 can also be set to six or eight, etc.

[0060] In this embodiment, it is exemplarily set that the multi-pole magnetic ring is supported on the rotating plate 11.

[0061] Among them, as Figures 3 - 7 shown, the rotating plate 11 is provided with a plurality of arc-shaped guide holes 111 that are circumferentially spaced apart. The fixed plate 12 is provided with a plurality of long-strip guide holes 121. The plurality of arc-shaped guide holes 111, the plurality of long-strip guide holes 121, and the plurality of positioning and magnetizing structures 14 are all correspondingly arranged one by one. The length direction of each long-strip guide hole 121 extends along the sliding direction of the corresponding positioning and magnetizing structure 14. The positioning and magnetizing structure 14 includes a magnetizing component 141 and a guide post 142 that are connected. The guide post 142 passes through the corresponding long-strip guide hole 121 and is inserted into the corresponding arc-shaped guide hole 111. The arc-shaped guide hole 111 can guide the corresponding guide post 142 to move along the length direction of the corresponding long-strip guide hole 121. The magnetizing component 141 can magnetize the multi-pole magnetic ring.

[0062] It can be understood that the plurality of long-strip guide holes 121 are also circumferentially spaced apart along the rotating plate 11.

[0063] During the process of driving the rotating plate 11 to rotate around its own central axis, the inner peripheral wall of the arc-shaped guide hole 111 applies a force to the guide post 142 therein, pushing the guide post 142 therein to move along the length direction of the corresponding long-strip guide hole 121, driving the corresponding magnetizing component 141 to slide synchronously, so that the multiple positioning and magnetizing structures 14 can approach or move away from each other synchronously, and the multi-pole magnetic ring can be clamped between the multiple magnetizing components 141.

[0064] In this embodiment, for the annular magnet, as Figure 7 shown, preferably, a plurality of arc-shaped guide holes 111 are circumferentially and spaced apart on the same circumference along the circumference of the rotating plate 11. It can further improve the accuracy of positioning the multi-pole magnetic ring to the optimal positioning position, and can further improve the reliability of setting the position of the fixed multi-pole magnetic ring. Further preferably, as Figure 7 shown, a plurality of arc-shaped guide holes 111 are evenly and circumferentially spaced apart on the same circumference along the circumference of the rotating plate 11. It can further improve the accuracy of positioning the multi-pole magnetic ring to the optimal positioning position.

[0065] In this embodiment, as Figure 7 shown, exemplarily, four long strip-shaped guide holes 121 are evenly and circumferentially spaced apart on the same circumference along the circumference of the rotating plate 11. That is, the four long strip-shaped guide holes 121 are distributed in a "cross" shape, and the intersection point of the "cross" shape is a point on the central axis of the rotating plate 11.

[0066] Specifically, as Figures 3 - 7 shown, the fixing plate 12 is provided with a plurality of limiting sliding grooves 122, and a plurality of magnetizing components 141 are correspondingly arranged and slidably matched with the plurality of limiting sliding grooves 122. The limiting sliding groove 122 is used to limit the magnetizing component 141 to slide along the extending direction of the corresponding long strip-shaped guide hole 121. It can be understood that the extending direction of each limiting sliding groove 122 is parallel to the length direction of the corresponding long strip-shaped guide hole 121. To prevent the magnetizing component 141 from rotating relative to the fixing plate 12 during the process of sliding along the extending direction of the corresponding long strip-shaped guide hole 121, so as to limit the magnetizing component 141 to only slide along the extending direction of the corresponding long strip-shaped guide hole 121, thereby further improving the reliability of setting the position of the multi-pole magnetic ring through the plurality of magnetizing components 141.

[0067] As Figure 7 shown, in this embodiment, the number of the limiting sliding grooves 122 is the same as the number of the positioning and magnetizing structures 14, both being four.

[0068] Specifically, as Figures 3 - 6 shown, the magnetizing component 141 includes an iron core 1411 and a magnetizing coil 1412 fixedly arranged on the iron core 1411, and the iron core 1411 and the magnetizing coil 1412 are electrically connected. When a low-frequency current is pre-applied to the positioning and magnetizing structure 14, the iron core 1411 is electrically connected to the power supply. Among them, Figure 6 exemplarily, the magnetizing coil 1412 is wound around the iron core 1411. It can be understood that the setting manner of fixedly arranging the magnetizing coil 1412 on the iron core 1411 can also be adaptively adjusted according to the actual working conditions. The setting manner of fixedly arranging the magnetizing coil 1412 on the iron core 1411 belongs to the prior art and will not be elaborated here.

[0069] Specifically, Figures 3 - 7 As shown, the iron core 1411 is slidably connected to the limiting sliding groove 122. Further, in this embodiment, as Figure 6 As shown, the exemplary iron core 1411 is formed by two vertically distributed parts connected by welding or screwing. It can be understood that the specific structural shape of the iron core 1411 can be adaptively set according to actual working conditions.

[0070] Preferably, if Figures 1 - 4 As shown, the positioning mechanism 1 also includes a protective housing 16 fixedly connected to the fixing plate 12, and the iron core 1411 partially extends out of the protective housing 16. This can protect the magnetizing component 141 and the multi-pole magnetic ring, and ensure that the iron core 1411 can be electrically connected to the power supply. Figure 1 and Figure 2 As shown, the protection shell 16 is provided with a water inlet 161 , a water outlet 162 and a cooling channel, and the cooling channel is connected to the water inlet 161 and the water outlet 162 , so that the temperature inside the protection shell 16 can be adjusted.

[0071] The positioning mechanism 1 further comprises a rotation driving assembly, which can drive the rotating plate 11 to rotate around its own central axis.

[0072] Specifically, Figure 2 As shown, the rotary drive assembly includes a rotary drive member 17 and a transmission gear, the transmission gear is connected to the output shaft of the rotary drive member 17, and the transmission gear is meshed with the toothed portion on the outer periphery of the rotating plate 11, and the rotary drive member 17 can drive the transmission gear to rotate around its own central axis, so as to drive the rotating plate 11 to rotate around its own central axis. Specifically, the rotary drive member 17 is a rotary motor.

[0073] As an alternative, the rotary drive assembly further includes a rotary drive member 17 and a rack, the rack is connected to the output end of the rotary drive member 17, and the rack is meshed with the toothed portion on the outer periphery of the rotating plate 11, and the rotary drive member 17 can drive the rack to move linearly. It can also drive the rotating plate 11 to rotate around its own central axis. Specifically, the rotary drive member 17 is a linear motor.

[0074] Among them, Figure 1 and Figure 3As shown, the positioning mechanism 1 also includes a fixed positioning column 15, which is inserted through the first support plate 13, the fixed plate 12 and the rotating plate 11, and the central axis of the positioning column 15 is colinear with the central axis of the rotating plate 11. Specifically, when the multi-polar magnetic ring is magnetized by the multi-polar magnetic ring magnetizing device, the multi-polar magnetic ring is first sleeved on the positioning column 15, and the multi-polar magnetic ring is supported on the fixed plate 12 or the rotating plate 11. Therefore, when the same low-frequency current is pre-applied to the multiple positioning magnetizing structures 14 simultaneously, the magnetic fields of the multiple positioning magnetizing structures 14 can stably drive the multi-polar magnetic ring to rotate around its own central axis, so as to improve the reliability of the multi-polar magnetic ring being rotated to the optimal magnetizing state.

[0075] Among them, Figure 1 and Figure 3 As shown, the multi-polar magnetic ring magnetizing device further includes a first thrust mechanism 2 and a second thrust mechanism 3, wherein the first thrust mechanism 2 can push the multi-polar magnetic ring along the axial direction of the positioning column 15 to be supported on the fixed plate 12 or the rotating plate 11, and the second thrust mechanism 3 can push the multi-polar magnetic ring away from the fixed plate 12 along the axial direction of the positioning column 15. Such a configuration can effectively improve the degree of automation of magnetizing the multi-polar magnetic ring by the multi-polar magnetic ring magnetizing device, and can effectively save labor costs.

[0076] Among them, Figure 1 and Figure 3 As shown, the first thrust mechanism 2 includes a first fixed driving member 21, and a first pressure rod sleeve 22 that is transmission-connected to the output end of the first driving member 21. The first driving member 21 can drive the first pressure rod sleeve 22 to move along the axial direction of the positioning column 15, so that the first pressure rod sleeve 22 can be sleeved on the positioning column 15 and abut against the upper end surface of the multi-polar magnetic ring. It can be understood that the first pressure rod sleeve 22 is located above the fixed plate 12. In this way, after the multi-polar magnetic ring is sleeved on the positioning column 15, the first thrust mechanism 2 can effectively push the multi-polar magnetic ring to be supported on the fixed plate 12 or the rotating plate 11.

[0077] Specifically, in this embodiment, the first driving member 21 is a first cylinder, and the first pressure rod sleeve 22 is fixedly connected to the first output rod of the first cylinder, so as to drive the first pressure rod sleeve 22 to move along the axial direction of the positioning column 15 .

[0078] Furthermore, if Figure 1 and Figure 3As shown, the first pressure rod sleeve 22 is provided with a first through hole 221 that penetrates in the axial direction, the first output rod of the first driving member 21 is provided with a second through hole 211 that penetrates the first through hole 221, and the positioning column 15 can be inserted into the first through hole 221 and the second through hole 211. So that the first pressure rod sleeve 22 can effectively push the multi-polar magnetic ring onto the fixed plate 12, so that the multi-polar magnetic ring is well supported on the fixed plate 12 or the rotating plate 11. Preferably, the axial length of the first pressure rod sleeve 22 is greater than the length of the positioning column 15 extending above the fixed plate 12.

[0079] As an alternative, the first driving member 21 is a linear motor, and the first pressure rod sleeve 22 is fixedly connected to the output end of the linear motor. It is understandable that the specific structure of the first thrust mechanism 2 is not limited, as long as it can drive the first pressure rod sleeve 22 to move along the axial direction of the positioning column 15.

[0080] Furthermore, in this embodiment, if Figure 1 and Figure 3 As shown, the first driving member 21 is located above the positioning mechanism 1 and is fixedly connected to the second support plate 41 . The second support plate 41 is connected to the top of the first support plate 13 through the first support column 42 .

[0081] Among them, Figure 1 and Figure 3 As shown, the second thrust mechanism 3 includes a second fixed driving member 31, and a second pressure rod sleeve 32 which is transmission-connected to the output end of the second driving member 31. The second pressure rod sleeve 32 is sleeved on the positioning column 15. The second driving member 31 can drive the second pressure rod sleeve 32 to move along the axial direction of the positioning column 15, so that the second pressure rod sleeve 32 can abut against the lower end surface of the multi-polar magnetic ring. In this way, after the multi-polar magnetic ring is magnetized, the second thrust mechanism 3 can effectively push the multi-polar magnetic ring away from the fixed plate 12.

[0082] Specifically, in this embodiment, the second driving member 31 is a second cylinder, and the second pressure rod sleeve 32 is fixedly connected to the second output rod of the second cylinder. As an alternative, the second driving member 31 is a linear motor, and the second pressure rod sleeve 32 is fixedly connected to the output end of the linear motor. It can be understood that the specific structure of the second thrust mechanism 3 is not limited, as long as it can drive the second pressure rod sleeve 32 to move along the axial direction of the positioning column 15.

[0083] Furthermore, if Figure 1 and Figure 3 As shown, in this embodiment, the second driving member 31 is located below the positioning mechanism 1 and is fixedly connected to the third support plate 43 , and the third support plate 43 is connected to the bottom of the first support plate 13 through the second support column 44 .

[0084] Furthermore, if Figure 3As shown, in this embodiment, the positioning post 15 is fixedly connected to the housing of the second driving member 31. In other embodiments, the positioning post 15 may also be fixedly connected to the third support plate 43, etc., as long as the installation position of the positioning post 15 can be fixed.

[0085] Specifically, as Figure 3 , Figure 5 and Figure 7 shown, the first support plate 13 is provided with a central hole 18 that penetrates the fixed plate 12 and the rotating plate 11. The positioning post 15 passes through the central hole 18, and the outer diameter of the second pressure rod sleeve 32 is smaller than the minimum diameter of the central hole 18. So that the second pressure rod sleeve 32 can effectively push the multi-pole magnetic ring away from the fixed plate 12.

For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the claims of the present invention.
