[0060] In order to make the content of the present utility model be more clearly understood, the following further describes the present utility model in detail according to specific embodiments and in conjunction with the accompanying drawings.

[0061] As Figures 1-5 shown, a motor magnet tile tightening tooling for tightening a magnet tile 1 in a motor housing assembly 2 includes:

[0062] A support base 3;

[0063] A central shaft pushing assembly, which is vertically and movably installed in the middle of the support base 3, and a plurality of upper-large-and-lower-small inclined conical surfaces are provided on the outer peripheral surface of the central shaft pushing assembly;

[0064] Six radial moving mechanisms 4, and the plurality of radial moving mechanisms 4 are uniformly arranged on the support base 3 along the circumferential direction with the central shaft pushing assembly as the center;

[0065] Six magnet tile limiting assemblies 5, and the magnet tile limiting assemblies 5 are installed on the corresponding radial moving mechanisms 4, and the magnet tile limiting assemblies 5 are adapted to radially move on the support base 3 through the radial moving mechanisms 4;

[0066] The magnet tile limiting assembly 5 is provided with a mating inclined surface on the side corresponding to the central shaft pushing assembly and matching with the inclined conical surface of the central shaft pushing assembly, and an elastic clamping portion is provided at the upper end of the magnet tile limiting assembly 5, and the elastic clamping portion is adapted to be actuated to loosen the clamping;

[0067] When the elastic clamping portion is actuated, the magnet tile 1 is attached to the magnet tile limiting assembly 5, the lower end of the magnet tile 1 abuts against the support base 3, and the upper end of the magnet tile 1 abuts against the elastic clamping portion of the magnet tile limiting assembly 5;

[0068] A jacking shaft assembly 6, which is installed on the motor housing assembly 2;

[0069] When the motor housing assembly 2 and the magnet tile 1 are assembled in combination, the jacking shaft assembly 6 is adapted to drive the central shaft pushing assembly to move in the vertical direction, so that the inclined conical surface of the central shaft pushing assembly abuts against the corresponding mating inclined surface on the magnet tile limiting assembly 5, and drives the magnet tile 1 on the magnet tile limiting assembly 5 to move radially outwards and closely adhere to the inside of the motor housing assembly 2.

[0070] In this embodiment, as Figures 1-2As shown in the figure, first, actuate the elastic clamping part of the magnetic tile limiting component 5 to loosen the elastic clamping part. At this time, place the magnetic tile 1 on the magnetic tile limiting component 5. Then, by setting a central axis pushing component on the support base 3 and arranging a plurality of upper-large and lower-small tapered surfaces on its outer peripheral surface, when installing the magnetic tile 1 on the motor housing component 2, the vertical movement of the central axis pushing component is driven by the top shaft component 6 installed on the motor housing component 2, so that the tapered surface of the central axis pushing component abuts against the mating inclined surface of the magnetic tile limiting component 5, thereby driving the magnetic tile 1 on the magnetic tile limiting component 5 to move radially outward and closely adhere to the inside of the motor housing component 2, realizing the installation of multiple magnetic tiles 1 being simultaneously tightened, ensuring the close fit of the magnetic tile 1 inside the motor housing component 2, improving the assembly efficiency, and being convenient to operate, reducing manual intervention.

[0071] After the above is completed, the magnetic tile 1 is fixed on the motor housing component 2, and the support base 3 starts to descend. The elastic clamping part of the magnetic tile limiting component 5 that abuts against the upper end of the magnetic tile 1 is pushed open by the upper end of the magnetic tile 1, and the entire motor magnetic tile tightening tooling slides out of the motor housing component 2 from below, completing the installation of the magnetic tile 1 inside the motor housing component 2.

[0072] In some embodiments, the number of the radial movement mechanisms 4 and the magnetic tile limiting components 5 is not limited to six and can be set according to specific requirements.

[0073] Specifically, as Figure 1 and Figure 3 shown, the central axis pushing component can have the following structure, including:

[0074] A reset spring assembly 71, the lower end of the reset spring assembly 71 abuts against the support base 3;

[0075] A tapered surface mating shaft 72, the tapered surface mating shaft 72 is vertically movably arranged on the support base 3, and the lower end of the tapered surface mating shaft 72 abuts against the upper end of the reset spring assembly 71;

[0076] A plurality of tapered surfaces are arranged circumferentially on the outer peripheral surface of the tapered surface mating shaft 72 with the axis of the tapered surface mating shaft 72 as the center.

[0077] In this embodiment, as Figures 1-3As shown, the central shaft pushing assembly further includes an abutting contact core, which is arranged on the conical surface mating shaft 72. The top shaft assembly 6 directly abuts against the abutting contact core. The abutting contact core is designed in a detachable form. After long-term use, the abutting contact core can be conveniently replaced. Moreover, by using the abutting contact core as the contact interface between the conical surface mating shaft 72 and the top shaft assembly 6, the wear of the conical surface mating shaft 72 can be reduced and its service life can be extended. In addition, it also includes a lower abutting limit fixing block for the return spring assembly. The lower abutting limit fixing block for the return spring assembly is installed on the support base 3, which provides a stable support point for the lower end of the return spring assembly 71, preventing it from shifting or deforming during the operation of the return spring assembly 71, ensuring the stable use of the entire central shaft pushing assembly during long-term use.

[0078] The main function of the return spring assembly 71 is to drive the conical surface mating shaft 72 to return to its original position after installation, facilitating the next use. And the return spring assembly 71 provides elastic support for the conical surface mating shaft 72, ensuring that the conical surface mating shaft 72 will not affect the movement of the magnetic tile limiting assembly 5 when not in use.

[0079] The conical surface mating shaft 72 is designed with a hollow overall structure. The lower half of its outer peripheral surface is cylindrical, and the upper half is provided with a conical surface. Six inclined conical surfaces are circumferentially arranged on the conical surface. The inclined conical surfaces adopt a planar design, which not only increases the effective contact area with the mating inclined surface of the magnetic tile limiting assembly 5, but also can convert the vertical movement into a radial thrust, thereby realizing the control of the magnetic tile limiting assembly 5.

[0080] In some embodiments, the number of the inclined conical surfaces of the conical surface mating shaft 72 is not limited to six, but is set according to the number of the corresponding magnetic tile limiting assemblies 5.

[0081] Specifically, as Figures 1-2 shown, the conical surface mating shaft 72 is also provided with a return spring limiting mechanism, which can be of the following structure, including:

[0082] A spring upper abutting bushing 73, which is coaxially sleeved on the conical surface mating shaft 72, and a through hole is radially provided on the spring upper abutting bushing 73;

[0083] A section of axially extending waist-shaped groove that penetrates radially is provided on the conical surface mating shaft 72;

[0084] A limit pin shaft 74, which passes through the waist-shaped groove of the conical surface mating shaft 72 and the through hole of the spring upper abutting bushing 73, axially restricting the sliding of the spring upper abutting bushing 73 on the waist-shaped groove of the conical surface mating shaft 72;

[0085] The upper end sleeve of the return spring assembly 71 is arranged on the conical surface matching shaft 72 and abuts against the lower end of the abutting shaft sleeve 73 on the spring.

[0086] In this embodiment, if Figure 3 As shown, the function of the reset spring limiting mechanism is to limit the movement of the reset spring assembly 71. The spring upper abutting sleeve 73 is coaxially sleeved on the conical surface matching shaft 72, and cooperates with the limiting pin 74 through the through hole and the waist groove to limit the axial sliding range of the spring upper abutting sleeve 73. Since the upper end of the reset spring assembly 71 abuts on the spring upper abutting sleeve 73, it is ensured that the reset spring assembly 71 is always within a certain range during the compression and release process.

[0087] When the telescopic length of the return spring assembly 71 needs to be adjusted, the limiting pin 74 of different specifications can be replaced or the waist groove length can be adjusted to meet different working requirements.

[0088] Specifically, Figure 1 and Figures 4-5 As shown, the support seat 3 also includes:

[0089] An annular abutting sleeve 31, which is arranged on the supporting seat 3 and has an annular flange extending upward;

[0090] The magnetic shoe tightening fixture mechanism also includes six radial displacement return springs 8, which are evenly arranged in the support seat 3 along the circumference of the annular abutment sleeve 31. One end of the radial displacement return spring 8 abuts against the magnetic shoe limit assembly 5 on the corresponding radial movement mechanism 4, and the other end abuts against the annular flange of the annular abutment sleeve 31.

[0091] The radial displacement return spring 8 is suitable for driving the magnetic shoe limit assembly 5 to return radially inward after the magnetic shoe limit assembly 5 moves radially outward.

[0092] In this embodiment, if Figures 1-2 and Figure 5 As shown, the function of the radial displacement return spring 8 is to drive the magnetic shoe limit assembly 5 on the radial moving mechanism 4 to move inward to complete the return after the magnetic shoe 1 is tightened and installed. A radial displacement return spring installation groove is also provided on the magnetic shoe limit assembly 5. The radial displacement return spring 8 abuts against one end of the magnetic shoe limit assembly 5 and extends into the radial displacement return spring installation groove.

[0093] In some embodiments, the number of radial displacement return springs 8 is not limited to six, and is set according to the specific number of corresponding radial movement mechanisms 4 .

[0094] Specifically, Figure 2 and Figures 4-5As shown, six radially through holes are uniformly arranged along the circumferential direction on the annular flange of the annular abutting sleeve 31. The radially through holes correspond to the corresponding radial movement mechanisms 4 one by one, and the radially through holes are adapted to allow the radial displacement return spring 8 to pass through;

[0095] The annular abutting sleeve 31 further includes a plurality of radially displaceable return spring abutting movable pieces 311. The radially displaceable return spring abutting movable pieces 311 are detachably mounted on the outside of the corresponding radially through holes;

[0096] The other end of the radial displacement return spring 8 is adapted to pass through the radially through hole and abut against the corresponding radially displaceable return spring abutting movable piece 311 on the annular flange.

[0097] In this embodiment, as Figure 2 and Figures 4-5 shown, a plurality of radially displaceable return spring abutting movable piece mounting grooves corresponding to the radial movement mechanisms 4 are also uniformly arranged along the circumferential direction on the annular flange of the annular abutting sleeve 31. The radially through holes are arranged on the radially displaceable return spring abutting movable piece mounting grooves;

[0098] The detachable design of the radially displaceable return spring abutting movable piece 311 on the annular abutting sleeve 31 not only provides an adjustable abutting point for the radial displacement return spring 8, but also facilitates the replacement and adjustment of the radial displacement return spring 8.

[0099] Specifically, as Figure 2 and Figure 5 shown, the magnetic tile limiting assembly 5 can be of the following structure, including:

[0100] A support rod 51, the lower end of the support rod 51 is mounted on the corresponding radial movement mechanism 4;

[0101] A magnetic tile abutting block 52, the magnetic tile abutting block 52 is detachably mounted on the support rod 51, and a magnetic tile abutting contact surface is provided on the magnetic tile abutting block 52;

[0102] A radial displacement abutting block 53, the radial displacement abutting block 53 is detachably mounted on the support rod 51, on the opposite side of the central shaft pushing assembly;

[0103] A mating inclined surface is provided on the radial displacement abutting block 53;

[0104] An elastic pressing piece 54, the elastic pressing piece 54 is hinged to the upper end of the support rod 51;

[0105] An elastic clamping portion is provided on the elastic pressing piece 54;

[0106] Two torsion springs 55, the torsion springs 55 are hinged on the support rod, one end of the torsion spring 55 abuts against the support rod 51, and the other end abuts against the elastic pressing piece 54;

[0107] When the magnetic tile 1 abuts against the magnetic tile abutting contact surface on the magnetic tile abutting block 52, the upper end of the magnetic tile 1 abuts against the elastic pressing piece 54.

[0108] In this embodiment, as Figure 1 and Figure 5 shown, the elastic pressing piece 54 is hinged on the support rod 51 and can flexibly adjust the angle. The torsion spring 55 provides appropriate pressure for the elastic pressing piece 54 to ensure that the magnetic tile 1 is always subjected to a certain clamping force during the assembly process.

[0109] One of the two torsion springs 55 is left-handed and the other is right-handed. In some embodiments, the number of torsion springs 55 is not limited to two and can be set according to specific requirements.

[0110] Specifically, as Figure 1 and Figure 5 shown, a lateral protrusion is provided on each of the left and right sides of the magnetic tile abutting block 52;

[0111] The distance between the two lateral protrusions is adapted to the width of the magnetic tile 1;

[0112] The two lateral protrusions are adapted to define the lateral position of the magnetic tile 1 on the magnetic tile abutting block 52.

[0113] Specifically, as Figure 5 shown, the motor magnetic tile tightening tooling further includes two magnetic members 56;

[0114] Two magnetic member mounting grooves adapted to the shape of the magnetic members 56 are provided on the magnetic tile abutting block 52;

[0115] The magnetic members 56 are embedded and installed in the magnetic member mounting grooves of the corresponding magnetic tile abutting block 52.

[0116] In this embodiment, as Figure 1 and Figure 5 shown, in the previous process, the elastic pressing piece 54 is first abutted and then released. When the robotic arm of the previous process places the magnetic tile 1 on the magnetic tile abutting block 52, the magnetic members 56 start to adsorb first, and the two lateral protrusions will guide the magnetic tile 1 into the correct position. This not only simplifies the assembly process, reduces human error, but also significantly improves the assembly accuracy and efficiency. The presence of the lateral protrusions effectively prevents the magnetic tile 1 from shifting or sliding laterally, especially when the tooling moves or is affected by external forces, and can maintain the stability of the magnetic tile 1.

[0117] Specifically, as Figure 1 shown, a glue coating layer is provided on the inner side of the motor housing assembly 2 and the outer side of the magnetic tile 1.

[0118] In this embodiment, as Figure 1As shown, in this embodiment, the motor housing assembly 2 and the magnetic tile 1 can be fixed by using an adhesive. A high-strength glue or epoxy resin is used to paste the magnetic tile 1 on the inner side of the motor housing assembly 2. The adhesive provides sufficient bonding force after curing, which can firmly fix the magnetic tile 1. At the same time, it will not cause mechanical stress to the magnetic tile 1.

[0119] Of course, in some embodiments, fixtures or fasteners designed to be installed in the motor housing assembly 2 can also be used to fix the magnetic tile 1. The magnetic tile 1 is fixed to the motor housing assembly 2 by snapping.

[0120] Specifically, as Figures 1-2 shown, the radial movement mechanism 4 can have the following structure, including:

[0121] A guide rail assembly, which is uniformly arranged on the support base 3 along the circumferential direction with the central shaft pushing assembly as the center;

[0122] A slider assembly, which is slidably arranged on the guide rail assembly;

[0123] The magnetic tile limiting assembly 5 is installed on the slider assembly.

[0124] In this embodiment, as Figure 2 shown, the radial movement mechanism 4 can specifically be a micro guide rail slider pair.

[0125] In this embodiment, as Figures 1-2 shown, the support base 3 further includes a guide plate. Six radial guide grooves are provided along the circumferential direction on the guide plate, and a through hole is provided in the center. The guide plate is installed on the annular abutting sleeve 31;

[0126] The support rod 51 of the magnetic tile limiting assembly 5 passes through the corresponding radial guide groove, and the central shaft pushing assembly passes through the through hole in the center of the guide plate

[0127] Six abutting limiting blocks are arranged on the guide plate along the circumferential direction with the central shaft pushing assembly as the center. The abutting limiting blocks are provided with a lower abutting surface and a vertical abutting surface. The lower end of the magnetic tile 1 abuts on the abutting limiting blocks. The magnetic tile limiting assembly 5 is driven by the radial displacement return spring 8 and abuts on the vertical abutting surface of the abutting limiting blocks on the side close to the center of the central shaft pushing assembly.
