[0043] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

The terms "first," "second," and similar words used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components.

Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly. To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0045] like Figures 1 to 4 As shown in the figure, this utility model embodiment provides a motor stator 4 assembly device, which mainly includes a platform base 1, a power component 2, and an expansion sleeve fixture 3.

[0046] The base 1 of the test stand has a rotatable spindle 11, and the power unit 2 is connected to the spindle 11 to drive the shaft to rotate freely.

[0047] The expansion sleeve fixture 3 is connected to the main shaft 11 and can rotate synchronously with the main shaft 11. The expansion sleeve fixture 3 includes at least a tensioning sleeve 30, a first tensioning block 31, a second tensioning block 32, and a tensioning drive component 34.

[0048] The tensioning sleeve 30 is coaxially arranged with the main shaft 11 and is used to pass through the center hole of the motor stator 4. It can be understood that the motor stator 4 can be fitted onto the tensioning sleeve 30.

[0049] The first end of the tensioning sleeve 30 is fitted onto the first tensioning block 31, and the second end of the tensioning sleeve 30 is fitted onto the second tensioning block 32.

[0050] The tension drive component 34 is fixed to the main shaft 11 and can rotate synchronously with the main shaft 11. The tension drive component 34 is connected to one of the tension blocks, and can drive the connected tension block to move closer to the other tension block, thereby expanding the ports at both ends of the tension sleeve 30 to prevent the motor stator 4 from separating from the tension sleeve 30, and thus fixing it to the tension sleeve 30. See Figure 4 As shown.

[0051] Alternatively, the tensioning drive component 34 can drive the connected tensioning block away from another tensioning block, thereby retracting the ports at both ends of the tensioning sleeve 30 so that the motor stator 4 can be separated from the tensioning sleeve 30, see Figure 3 As shown.

[0052] The stator assembly device of this embodiment can insert the tensioning sleeve 30 into the center hole of the motor stator 4, and then drive the two tensioning blocks to move closer together through the tensioning drive component 34 to expand the two ends of the tensioning sleeve 30, thereby fixing the motor stator 4. When it is necessary to remove the motor stator 4, the two tensioning blocks are controlled to separate to retract the tensioning sleeve 30, and then the motor stator 4 can be removed. This stator assembly device can effectively reduce the physical labor requirements of assembly workers, improve assembly efficiency, and the automatic cornering reduces manual turning. At the same time, it also improves the assembly quality. The tensioning sleeve 30 fixes the motor stator 4 well, so that other components have a positioning reference and improve the overall concentricity.

[0053] like Figure 1 and Figure 2 As shown, in some embodiments, the power component 2 may include a drive motor 21 and a pulley mechanism. The pulley mechanism may include a driving pulley 22, a driven pulley 24, and a conveyor belt 23 connecting the driving pulley 22 and the driven pulley 24.

[0054] The drive motor 21 can be connected to the driving pulley 22, and the driven pulley 24 can be connected to the main shaft 11. The drive motor 21 can drive the main shaft 11 to rotate through the pulley mechanism.

[0055] Of course, in some other embodiments, the pulley mechanism can be replaced by a sprocket mechanism.

[0056] It should be noted that the drive motor 21 in this embodiment can be fixed on the same workbench as the stand base 1 to ensure its stability.

[0057] In some embodiments, the platform base 1 can be fixed on a workbench. The platform base 1 has shaft holes 10 extending through its opposite ends. Bearings are respectively provided at both ends of the shaft holes 10. The drive shaft passes through the shaft holes 10, and both ends of the drive shaft can be supported by the bearings, thereby enabling the drive shaft to rotate freely. The specific shape of the platform base 1 is not specifically limited in the embodiments of this application.

[0058] like Figure 5 As shown, in some embodiments, the tensioning sleeve 30 can be made of some plastic materials, such as plastic, so that its two ends can expand and retract quickly.

[0059] In some embodiments, the first end of the tensioning sleeve 30 may be provided with a plurality of first dividing grooves 301 spaced apart along the circumferential direction, and the second end of the tensioning sleeve 30 may be provided with a plurality of second dividing grooves 302 spaced apart along the circumferential direction, wherein the extending direction of each dividing groove is consistent with the axial direction of the tensioning sleeve 30.

[0060] In this design, one end of the first dividing groove 301 extends through to the end face of the first end of the tensioning sleeve 30, and the other end extends along the end face near the second end of the tensioning sleeve 30, but does not extend to the end face of the second end of the tensioning sleeve 30. The structure of the second dividing groove 302 is similar, with dividing grooves provided at both ends of the tensioning sleeve 30 to facilitate the expansion of both ends of the tensioning sleeve 30.

[0061] In some embodiments, the inner wall surface of the first end of the tensioning sleeve 30 has a first conical surface, and the inner wall surface of the second end has a second conical surface.

[0062] The outer peripheral surface of the first tensioning block 31 has a third conical surface that matches the first conical surface, and the outer peripheral surface of the second tensioning block 32 has a fourth conical surface that matches the second conical surface. When the two tensioning blocks approach each other, the expansion or separation of the port of the tensioning sleeve 30 can be achieved by the cooperation of the conical surfaces of the two tensioning blocks with the conical surface of the tensioning sleeve 30.

[0063] like Figure 3 and Figure 4 As shown, in some embodiments, the second tensioning block 32 may be connected to the main shaft 11. The tensioning drive component 34 may include a drive cylinder 341 and a tensioning shaft 342, and the drive cylinder 341 may be fixed on the main shaft 11.

[0064] The tensioning shaft 342 can be inserted into the tensioning sleeve 30, and the tensioning shaft 342 is coaxial with the tensioning sleeve 30. The first end of the tensioning shaft 342 can be connected to the first tensioning block 31, and the second end of the tensioning shaft 342 can be connected to the piston rod of the drive cylinder 341. The drive cylinder 341 is used to drive the tensioning shaft 342 to move along the axial direction of the tensioning sleeve 30, thereby driving the first tensioning block 31 to move synchronously, so as to realize that the two tensioning blocks approach or separate from each other.

[0065] The drive cylinder 341 can be a pneumatic cylinder or a hydraulic cylinder, etc. The connection method between the drive cylinder 341 and the main shaft 11 is not specifically limited, and the drive cylinder 341 can be fixed to the end of the rotating shaft.

[0066] The connection method between the tensioning shaft 342 and the first tensioning block 31 is not specifically limited and can be achieved through threaded connection. For example, the center hole of the first tensioning block 31 can have an internal thread, and the outer circumferential surface of the first end of the tensioning shaft 342 can have an external thread that mates with the internal thread.

[0067] like Figure 3 and Figure 4 As shown, in some embodiments, the spindle 11 can be a hollow shaft, and the internal space of the spindle 11 can form an inner cavity 12.

[0068] The end of the main shaft 11 opposite to the second tensioning block 32 has a through hole communicating with the inner cavity 12 of the main shaft 11, and the second tensioning block 32 has a central hole coaxial with the through hole.

[0069] The drive cylinder 341 can be located in the inner cavity 12 of the main shaft 11 and connected to the main shaft 11. The second end of the tensioning shaft 342 can extend into the central hole of the second tensioning block 32. The piston rod of the drive cylinder 341 can extend into the central hole of the second tensioning block 32. The piston rod of the drive cylinder 341 can pass through the through hole on the main shaft 11 and extend into the central hole of the second tensioning block 32 to connect with the tensioning shaft 342.

[0070] Furthermore, the end of the main shaft 11 away from the second tensioning block 32 can be open, allowing installers to install and remove the drive cylinder 341 in the inner cavity 12 through this open end.

[0071] like Figure 3 and Figure 4 As shown, the end face of the main shaft 11 opposite to the second tensioning block 32 may have a boss, and the second tensioning block 32 may have a groove that engages with the boss. The second tensioning block 32 can be connected to the main shaft 11 through the engagement of the boss and the groove, and when the second tensioning block 32 is connected to the rotating shaft, it can rotate synchronously with the rotating shaft.

[0072] like Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, in some embodiments, the tensioning drive component 34 may further include a sleeve 35, a first spring 36, and a second spring 37 located within the tensioning sleeve 30.

[0073] The inner circumferential wall of the tensioning sleeve 30 may have a first annular stop 300, and a first spring 36 is sleeved on the tensioning shaft 342. The first end of the first spring 36 abuts against the first tensioning block 31, and the second end abuts against the first annular stop 300.

[0074] The sleeve 35 is fitted onto the tensioning shaft 342. The sleeve 35 may include a cylindrical body 351 and a second annular stop 352 provided on the cylindrical body 351. The first annular stop 300 may be opposite to the second annular stop 352. The second spring 37 may be fitted onto the cylindrical body 351 of the sleeve 35. The first end of the spring may abut against the first annular stop 300, and the second end may abut against the second annular stop 352.

[0075] As the tensioning shaft 342 moves the first tensioning block 31 closer to the second tensioning block 32, the first spring 36 and the second spring 37 can be compressed respectively to minimize the movement of the tensioning sleeve 30 along its axial direction. As the first tensioning block 31 moves away from the second tensioning block 32, the two springs are released respectively. The first spring 36 and the second spring 37 abut against the first annular stop 300 respectively to prevent the tensioning sleeve 30 from moving along its axial direction during the process of the two tensioning blocks approaching or separating.

[0076] In some embodiments, the outer diameter of the cylindrical portion 351 may be smaller than the central hole of the second tensioning block 32, at least a portion of the cylindrical portion 351 extends into the central hole of the second tensioning block 32, and the second annular stop 352 on the cylindrical portion 351 may abut against the second tensioning block 32, thereby ensuring the stability of the sleeve 35 during the compression of the spring.

[0077] The above description is intended to be illustrative and not restrictive. Those skilled in the art can make variations, modifications, substitutions, and alterations to the above embodiments within the scope of this disclosure. Moreover, the above examples (or one or more of them) can be used in combination with each other, and these embodiments can be combined with each other in various combinations or arrangements.
