Abstract
Description
Technical Field
[0001] The present application relates to the field of motor technology, and in particular to a rotor slice sorting and a rotor slice sorting and positioning device. Background Art
[0002] After the rotor sheets are stamped, they need to be stacked together. Since there are holes on the rotor sheets, the stacked rotor sheets need to be able to align the holes before they can be stamped. The current method requires stacking one sheet at a time to achieve alignment, which is too inefficient. Utility Model Content
[0003] The purpose of the present application is to provide a rotor wafer sorting and a rotor wafer sorting positioning device, which can increase the positioning efficiency of the rotor wafer sorting.
[0004] In the first aspect, the present application provides a rotor sheet sorting method using the following technical solution:
[0005] A rotor chip sorting device comprises a chip sorting body, a circular hole is formed on the chip sorting body, and a notch is formed on the inner wall of the circular hole.
[0006] By adopting the above technical solution, the rotor sheet is hung on the motor output shaft by gravity, and then the motor output shaft is rotated, and friction is generated between the motor output shaft and the inner wall of the circular hole, and the rotor sheet is driven to rotate by friction. When the rotor sheet rotates to the position where the notch corresponds to the rotating shaft, the rotor sheet falls under the action of gravity, so that the motor output shaft is inserted into the notch. At this time, the motor output shaft continues to rotate, and the rotor sheet whose notch is stuck in the motor output shaft is limited by the inner wall of the notch, so that it does not continue to rotate with the motor output shaft. When the notches on all the rotor sheets are stuck in the motor output shaft, all the rotor sheets do not rotate at this time, and the motor is turned off to complete the alignment of several rotor sheets. The efficiency of aligning the rotor sheets is increased.
[0007] Optionally, the notch is semicircular.
[0008] By adopting the above technical solution, the motor output shaft is a round rod, and the notch is set to be semicircular, so that the notch is more compatible with the motor output shaft and the motor output shaft and the notch fit more tightly.
[0009] In the second aspect, the present application provides a rotor arrangement and positioning device that adopts the following technical solution:
[0010] A rotor sheet sorting and positioning device comprises a driving member and a rotating shaft, wherein the rotating shaft is fixedly connected to the output end of the driving member and can be driven to rotate by the driving member, and the outer diameter of the rotating shaft is smaller than the inner diameter of the notch.
[0011] By adopting the above technical solution, the driving member drives the rotating shaft to rotate, thereby driving the rotor slices to rotate. Because the output shaft of the driving member is usually not long, by increasing the rotating shaft, the number of rotor slices that can be installed is increased, further increasing the positioning efficiency of the rotor slices.
[0012] Optionally, a limit plate is further included, wherein the limit plate is connected to an end of the rotating shaft away from the driving member.
[0013] By adopting the above technical solution and providing a limit plate, the limit plate is used to limit the position of the rotor slice, thereby reducing the possibility of the rotor slice falling off the rotating shaft during the rotation process.
[0014] Optionally, the limit plate is rotatably connected to the rotating shaft, a sleeve is fixedly connected to the housing of the driving member, a limit shaft is connected to the limit plate, the limit shaft can be inserted into the sleeve, the outer diameter of the limit shaft is smaller than the inner diameter of the notch, a limit ring is sleeved on the rotating shaft, the outer diameter of the limit ring is larger than the inner diameter of the notch and is used to limit the insertion of the rotating shaft into the notch;
[0015] The distance between the limiting shaft and the limiting ring is equal to the inner diameter of the circular hole, and the rotating shaft is located below the limiting shaft.
[0016] By adopting the above technical solution, the rotating shaft drives the limit ring to rotate, and the limit ring drives the rotor plate to rotate. When the notch on the rotor plate corresponds to the position of the limit shaft, the rotor plate falls under the action of gravity, so that the limit shaft is inserted into the notch and the limit ring is separated from the rotor plate, reducing the wear of the rotor plate after it has been positioned.
[0017] Optionally, a through hole is provided on the limit plate, the rotating shaft is inserted into the through hole and is rotatably connected to the limit plate, a limiting sleeve is provided at one end of the rotating shaft away from the driving member, the limiting sleeve is provided on the rotating shaft and is threadedly connected to the rotating shaft, and the limiting sleeve is used to limit the separation of the limit plate and the rotating shaft from each other.
[0018] By adopting the above technical solution, the shaft is inserted into the through hole to realize the detachable connection of the limit plate, and the limit sleeve is used to limit the limit plate from being disengaged from the shaft, which facilitates the installation of the limit plate and reduces the possibility of the limit plate being separated from the shaft.
[0019] Optionally, there are two limiting sleeves, both of which are screwed onto the rotating shaft and the two limiting sleeves sandwich the limiting plate.
[0020] By adopting the above technical solution and setting two limit sleeves, the possibility of the limit plate sliding toward the rotor sheet direction during the rotation of the shaft is reduced, thereby reducing the squeezing of the rotor sheet by the limit plate, reducing the friction between the rotor sheet and the limit plate, and reducing the difficulty of rotating the rotor sheet.
[0021] Optionally, a rubber sleeve is sleeved on the limiting ring, and the outer diameter of the rubber sleeve is smaller than the inner diameter of the notch.
[0022] By adopting the above technical solution, the friction between the limit ring and the rotor plate is increased by arranging the rubber sleeve, so as to facilitate the rotation of the rotor plate.
[0023] In summary, the present application includes at least one of the following beneficial technical effects:
[0024] 1. The sub-slice is hung on the motor output shaft by gravity, and then the motor output shaft is rotated, and friction is generated between the motor output shaft and the inner wall of the circular hole, which drives the rotor slice to rotate. When the rotor slice rotates to the position where the notch corresponds to the shaft, the rotor slice falls under the action of gravity, so that the motor output shaft is inserted into the notch. At this time, the motor output shaft continues to rotate, and the rotor slice whose notch is stuck in the motor output shaft is limited by the inner wall of the notch, so that it does not continue to rotate with the motor output shaft. When the notches on all the rotor slices are stuck in the motor output shaft, all the rotor slices will not rotate, and the motor will be turned off to complete the alignment of several rotor slices. The efficiency of aligning the rotor slices is increased;
[0025] 2. The drive member drives the rotating shaft to rotate, thereby driving the rotor sheet to rotate. Because the output shaft of the drive member is usually not long, by increasing the rotating shaft, the number of rotor sheets that can be set is increased, further increasing the positioning efficiency of the rotor sheets;
[0026] 3. Rotate the rotating shaft to drive the limit ring to rotate, and the limit ring drives the rotor plate to rotate. When the notch on the rotor plate corresponds to the position of the limit shaft, the rotor plate falls under the action of gravity, so that the limit shaft is inserted into the notch and the limit ring is separated from the rotor plate, reducing the wear of the rotor plate after it has been positioned.

[0031] The following is combined with Figure 1 -Attached Figure 3 , further details of this application are given.
[0032] Embodiment 1:
[0033] A rotor slice, referring to Figure 1 and Figure 2 , including a wafer sorting body 1, a circular hole 11 is opened on the wafer sorting body 1, in this embodiment, the circular hole 11 is located at the center of the wafer sorting, a notch 12 is opened on the inner wall of the circular hole 11, in this embodiment, the notch 12 is semicircular, and in other embodiments, the notch 12 can be other shapes.
[0034] A rotor sheet sorting and positioning device includes a driving member 2 and a rotating shaft 3. The rotating shaft 3 is fixedly connected to the output end of the driving member 2. In this embodiment, the driving member 2 is a motor. In other embodiments, the driving member 2 can be other devices as long as it can drive the rotating shaft 3 to rotate. The outer diameter of the rotating shaft 3 is smaller than the inner diameter of the notch 12, and the rotating shaft 3 can be inserted into the notch 12.
[0035] The implementation principle of the embodiment of the present application is as follows: when a stack of rotor sheets needs to be aligned, a stack of rotor sheets is sleeved on the rotating shaft 3. At this time, the rotor sheets are hung on the rotating shaft 3 by gravity, and then the driving member 2 is operated to drive the rotating shaft 3 to rotate. Friction is generated between the rotating shaft 3 and the inner wall of the circular hole 11, and the rotor sheets are driven to rotate by the friction. When the rotor sheets rotate to the position where the notch 12 corresponds to the rotating shaft 3, the rotor sheets fall under the action of gravity, so that the rotating shaft 3 is inserted into the notch 12. At this time, the rotating shaft 3 continues to rotate, and the rotor sheets inserted into the rotating shaft 3 by the notch 12 are limited by the inner wall of the notch 12, so that they do not continue to rotate with the rotating shaft 3. When the notches 12 on all the rotor sheets are inserted into the rotating shaft 3, all the rotor sheets do not rotate, and the driving member 2 is closed to complete the alignment of several rotor sheets.
[0036] Embodiment 2:
[0037] The structure of the present embodiment 2 is substantially the same as that of the embodiment 1, and the difference lies in the improvement of the rotor wafer positioning device.
[0038] Reference Figure 3 A rotor sheet positioning device also includes a limit plate 4, which is connected to the end of the rotating shaft 3 away from the driving member 2. In this embodiment, a through hole is opened on the limit plate 4, and the rotating shaft 3 passes through the limit plate 4 to realize the rotational connection between the rotating shaft 3 and the limit plate 4. In other embodiments, the rotating shaft 3 can be rotationally connected to the limit plate 4 through a bearing. In the embodiment of the present application, the rotational connection between the limit plate 4 and the rotating shaft 3 is realized by inserting the rotating shaft 3 into the limit plate 4, which is convenient for the installation and disassembly of the limit plate 4.
[0039] In order to reduce the separation of the limit plate 4 and the rotating shaft 3 during the rotation of the rotating shaft 3, a limit sleeve 5 is provided at the end of the rotating shaft 3 away from the driving member 2, and the outer diameter of the limit sleeve 5 is larger than the inner diameter of the through hole. The limit sleeve 5 is sleeved on the rotating shaft 3 and is threadedly connected to the rotating shaft 3. When installing the limit plate 4, the rotating shaft 3 is first inserted into the through hole, and then the limit sleeve 5 is threadedly connected to the rotating shaft 3, so that during the rotation of the rotating shaft 3, the limit sleeve 5 limits the limit plate 4 from sliding out of the rotating shaft 3.
[0040] In order to reduce the sliding of the limit plate 4 toward the rotor sheet direction during the rotation of the shaft 3 and to squeeze the rotor sheet, two limit sleeves 5 are provided. The two limit sleeves 5 are both sleeved on the shaft 3 and threadedly connected to the shaft 3. The limit plate 4 is arranged between the two limit sleeves 5 and is limited by the two limit sleeves 5.
[0041] When installing the limit plate 4 , firstly screw one limit sleeve 5 onto the rotating shaft 3 , then insert the rotating shaft 3 into the through hole, and finally screw another limit sleeve 5 onto the rotating shaft 3 , thereby completing the installation of the limit plate 4 .
[0042] In other embodiments, the limiting sleeve 5 close to the driving member 2 is fixedly connected to the rotating shaft 3 , and the limiting sleeve 5 far from the driving member 2 is threadedly connected to the rotating shaft 3 .
[0043] A sleeve 21 is fixedly connected to the outer shell of the driving member 2, and a limiting shaft 6 is connected to the limiting plate 4. The outer diameter of the limiting shaft 6 is smaller than the inner diameter of the notch 12 and can be inserted into the notch 12. The end of the limiting shaft 6 away from the limiting plate 4 is inserted into the sleeve 21. A limiting ring 7 is fixedly sleeved on the rotating shaft 3. The outer diameter of the limiting ring 7 is larger than the inner diameter of the notch 12. The position of the limiting ring 7 corresponds to the position of the notch 12 and is used to limit the insertion of the rotating shaft 3 into the notch 12. The distance between the limiting shaft 6 and the limiting ring 7 is equal to the inner diameter of the circular hole 11.
[0044] When in use, the limit shaft 6 and the rotating shaft 3 are inserted into the circular hole 11 at the same time. At this time, the limit ring 7 and the rotating shaft 3 are in contact with the inner wall of the circular hole 11, and the limit shaft 6 is located above the rotating shaft 3. In this embodiment, the limit shaft 6 is directly above the rotating shaft 3.
[0045] The rotating shaft 3 drives the limit ring 7 to rotate, and the limit ring 7 drives the rotor plate to rotate. When the notch 12 on the rotor plate corresponds to the position of the limit shaft 6, the rotor plate falls under the action of gravity, so that the limit shaft 6 is inserted into the notch 12 and the limit ring 7 is separated from the rotor plate, reducing the wear of the rotor plate after it has been positioned.
[0046] In this embodiment, a rubber sleeve is provided on the limit ring 7. By providing the rubber sleeve, the friction between the limit ring 7 and the rotor blade is increased. In this embodiment, in order to further increase the friction between the limit ring 7 and the rotor blade, friction patterns are provided on the outer surface of the rubber sleeve.
[0047] The implementation principle of this embodiment 2 is as follows: first, a plurality of rotor discs are sleeved on the rotating shaft 3, and then the limiting plate 4 is fixed on the rotating shaft 3 through the limiting sleeve 5 and the limiting rod is inserted into the sleeve 21 through the circular hole 11. At this time, the limiting ring 7 and the limiting shaft 6 are both in contact with the inner wall of the circular hole 11, and then the driving member 2 is turned on to drive the rotating shaft 3 to rotate, thereby driving the limiting ring 7 to rotate, and the limiting ring 7 drives the rotor disc to rotate. When the notch 12 corresponds to the position of the limiting shaft 6, the rotor disc falls, and the limiting shaft 6 is inserted into the notch 12. The limiting ring 7 is separated from the rotor disc. At this time, the positioning of one rotor disc is completed. When the notches 12 on all rotor discs are inserted into the limiting shaft 6, the positioning of a plurality of rotor discs is completed.
[0048] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
