[0048] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention.

[0049] Implementation Column 1

[0050] like Figure 1-11 As shown, a motor stator assembly and rotor assembly assembly tool includes a stator body 5 and a rotor body 4 matched with the stator body 5, and also includes:

[0051] A support frame 1, on which a first cylinder 2 is disposed, and an output end of the first cylinder 2 is rotatably connected to an extrusion rod 22;

[0052] A pressing unit 3, which is disposed on the support frame 1 and includes a support cover 32 that matches the extrusion rod 22, and a clamping block 34 for clamping the rotor body 4 is disposed in a circumferential array on the support cover 32;

[0053] The clamping unit 6 is disposed on the support frame 1 and clamps the stator body 5 . When the first cylinder 2 is working, the extrusion rod 22 is controlled to push the rotor body 4 through the support cover 32 to be assembled on the stator body 5 .

[0054] Specifically, the stator body 5 includes a housing 51 and a stator core disposed in the housing 51, and the rotor body 4 includes a hollow rotor and a slip ring 41. A bearing 7 is disposed at one end of the hollow rotor, and the other end is engaged with the bearing 7 at the housing 51. The hollow rotor is installed in the housing 51, and the slip ring 41 is covered on the housing 51 to complete the assembly of the motor as a whole (such as Fig.11 shown);

[0055] Furthermore, the support frame 1 is assembled by two side plates and a top plate through bolts, a limit plate 20 is arranged on one side of the top plate, and a first cylinder 2 is arranged on the other side thereof, the output shaft of the first cylinder 2 is rotatably connected with the extrusion rod 22, and when not assembled, one end of the extrusion rod 22 is attached to the limit plate 20, and the pressing unit 3 and the clamping unit 6 are both arranged between the two side plates, when the stator body 5 and the rotor body 4 are assembled, the stator body 5 is clamped to the bottom of the support cover 32 by the clamping unit 6, and the rotor body 4 is fixed to the support cover 32 by the clamping block 34, and then The first cylinder 2 outputs, so that the extrusion rod 22 applies thrust to the support cover 32, so that the support cover 32 pushes the stator body 5 to slide toward the rotor body 4 until the rotor body 4 is assembled in the stator body 5. The clamping block 34 has a supporting portion 341 and a fitting portion 342. The fitting portion 342 is made of rubber and has directional grooves in a linear array on the contact surface with the rotor body 4, which improves the clamping effect of the rotor body 4. During assembly, the rotor body 4 is manually or mechanically fitted with one end face of the supporting portion 341 to improve the assembly accuracy of the rotor body 4 and the stator body 5.

[0056] Furthermore, the device can clamp the slip ring 41 or the bearing 7 through the clamping block 34 and assemble it to the stator body 5 to complete the assembly of the motor.

[0057] As a further embodiment provided by the present invention, the pressing unit 3 further includes a first bracket 30 disposed on the support frame 1, and a second bracket 31 is disposed on the first bracket 30;

[0058] The first bracket 30 is provided with a motor 37, and the output end of the motor 37 is provided with a first pulley 371;

[0059] The second bracket 31 cooperates with the extrusion rod 22 , a second pulley 38 is clamped on the extrusion rod 22 , a synchronous belt 36 is arranged between the second pulley 38 and the first pulley 371 , and a slot 310 cooperating with the support cover 32 is opened on the second bracket 31 .

[0060] Specifically, the first bracket 30 is fixed to the support frame 1 by bolts, and the side surface of the first bracket 30 is triangular, which improves the support effect of the motor 37, and the second bracket 31 is fixed to the first bracket 30, which plays the role of guiding and supporting the extrusion rod 22. The model of the motor 37 is: MHMF042L1U2M2, and the output is carried out through the motor 37, thereby driving the second pulley 38 to rotate through the first pulley 371 through the synchronous belt 36. Under the rotation drive of the second pulley 38, the turntable 323 on the support cover 32 rotates, so that the clamping block 34 on the support cover 32 slides relative to or toward each other to clamp the rotor body 4, and the support cover 32 does not rotate during the clamping process. Since the support cover 32 is provided with a support column 35, the support column 35 is engaged in the slot 310 of the second bracket 31, and the rotation of the support cover 32 is limited by the slot 310.

[0061] As a further embodiment of the present invention, a fixed disk 321 is provided at one end of the support cover 32, and a rotating disk 323 cooperating with the extrusion rod 22 is threadedly connected at the other end thereof, a push rod 3231 cooperating with the second pulley 38 is provided on the rotating disk 323, a first spring 3230 is provided between the push rod 3231 and the rotating disk 323, and a guide disk 322 is provided on the rotating disk 323;

[0062] The fixing plate 321 is provided with a first sliding groove 3211 , the guiding plate 322 is provided with a second sliding groove 3221 , and the clamping block 34 is located in the first sliding groove 3211 and the second sliding groove 3221 and slides therein.

[0063] Specifically, the fixed plate 321 is specifically clamped on the support cover 32 to maintain a fixed state, and the guide plate 322 is arranged in the support cover 32, but there is a certain gap between the outer ring of the guide plate 322 and the inner wall of the support cover 32. When clamping the rotor body 4, the turntable 323 is rotated to make the guide plate 322 rotate in the support cover 32 and slide axially downward, so that the clamping block 34 slides along the first slide groove 3211 under the push of the second slide groove 3221, that is, multiple clamping blocks 34 slide relative to or toward each other until the clamping of the rotor body 4 is completed. The number of clamping blocks 34, the first slide groove 3211 and the second slide groove 3221 is the same, and at least three groups are set.

[0064] The second pulley 38 is provided with an inclined groove, which fits with the inclined portion 3233 of the push rod 3231. Under the elastic push of the first spring 3230, the push rod 3231 fits in the inclined groove. When the second pulley 38 rotates, the turntable 323 located on the rotating cover is driven to rotate through the push rod 3231. During the rotation of the turntable 323, the rotating cover is in a fixed state.

[0065] As a further embodiment of the present invention, a cover plate 3232 is clamped on the turntable 323, a slider 3235 is slidably arranged between the cover plate 3232 and the turntable 323, a second spring 3234 matching with the turntable 323 is arranged on the slider 3235, and the extrusion rod 22 is located at the axis of the slider 3235 and slides;

[0066] The fixing plate 321 is threadedly connected with an adjusting rod 33 .

[0067] Specifically, the cover plate 3232 is disc-shaped, and a circular hole is opened at the axis center of the cover plate 3232. The diameter of the circular hole is larger than the diameter of the extension portion on the extrusion rod 22. The extrusion rod 22 slides at the axis center of the slider 3235 through the extension portion. The extension portion is provided with a limiting block to prevent the extrusion rod 22 from separating from the slider 3235. When the rotor body 4 and the stator body 5 are assembled, the pre-adjustment rod 33 will pass through the center hole of the stator assembly bearing 7. At this time, under the action of the adjustment rod 33, the slider 3235 is located between the cover plate 3232 and the turntable 323 and slides, thereby improving the coaxiality of the rotor body 4 and the stator body 5, reducing the offset error generated during clamping, and improving the assembly accuracy. After the assembly is completed, the slider 3235 is pushed back to the axis center of the turntable 323 by the spring resistance of the second spring 3234.

[0068] As a further embodiment of the present invention, a support column 35 is provided on the support cover 32, and the support column 35 cooperates with the card slot 310. The support column 35 is two pieces that are connected to the support cover 32. The support column 35 is engaged with the card slot 310, so that when the rotor is clamped, the support cover 32 is restricted by the support column 35 to keep it in a prohibited state.

[0069] As a further embodiment of the present invention, the clamping unit 6 also includes a base 62 and a second cylinder 63 arranged on the base 62 . A push plate 64 is arranged at the output end of the second cylinder 63 . An arc block 61 for clamping the stator body 5 is arranged on the push plate 64 .

[0070] Specifically, under the output action of the second cylinder 63, the push plate 64 slides on the base 62, so as to clamp the stator body 5 through the arc block 61. The arc block 61 is a rubber block, which increases the friction between the arc block 61 and the stator body 5 and improves the supporting effect on the stator body 5.

[0071] As a further embodiment of the present invention, a support plate 65 is provided on the base 62, a sliding plate 653 is slidably provided on the support plate 65, and a rotating seat 656 is provided on the sliding plate 653;

[0072] The support plate 65 is symmetrically slidably provided with a stabilizing block 651 matched with the stator body 5 , and a connecting rod 654 is provided between the stabilizing block 651 and the rotating seat 656 .

[0073] Specifically, the stator body 5 is placed on the sliding plate 653, and the sliding plate 653 is pressed by the stator body 5 to slide downward on the support plate 65. The sliding plate 653 drives the stabilizing blocks 651 on both sides to slide relative to each other through the connecting rod 654 to clamp the end of the stator body 5. During assembly, this prevents the stator body 5 from pushing out the bearing 7.

[0074] As a further embodiment of the present invention, a threaded portion 6531 is provided on the sliding plate 653 , a sleeve ring 655 threadedly connected to the threaded portion 6531 is provided on the rotating seat 656 , and a third spring 652 is provided between the sliding plate 653 and the support plate 65 .

[0075] Specifically, the collar 655 is rotated to adjust the position of the rotating seat 656 on the sliding plate 653, that is, to adjust the clamping distance between the two stabilizing blocks 651 to adapt to stator assemblies of different specifications.

[0076] As an embodiment further provided by the present invention, a raising block 11 is arranged on the support frame 1, and a bottom plate 12 is arranged at the bottom. The bottom plate 12 is a rubber plate. The raising block 11 is used to prevent the sliding plate 653 from contacting the bottom ground, and a mounting hole is opened on the bottom plate 12, which can be mounted on other equipment together with others. The rubber material improves the fixing effect of the bottom plate 12, making the stator body 5 and the rotor body 4 more stable during assembly.

[0077] Implementation column 2

[0078] A method for assembling a stator assembly and a rotor assembly of a motor 37, specifically comprising the following steps:

[0079] S01. Place the rotor body 4 on the clamping block 34, and make the upper end surface of the rotor body 4 fit to the abutment portion 341 of the clamping block 34. At this time, the support column 35 is clamped into the slot 310 of the second bracket 31. The motor 37 controls the first pulley 371 to rotate, and drives the second pulley 38 to rotate through the synchronous belt 36. During the rotation process, the second pulley 38 will make the turntable 323 and the guide plate 322 rotate through the push rod 3231, so that the clamping block 34 slides along the first slide groove 3211 under the push of the second slide groove 3221, until the abutment portion 342 of the clamping block 34 contacts the inner wall of the rotor body 4, and the rotor body 4 is clamped.

[0080] S02, place the stator body 5 at the clamping unit 6, and make it contact with the sliding plate 653, and then press the stator body 5, so that the sliding plate 653 slides on the support plate 65, and at the same time, the connecting rod 654 pulls the two stabilizing blocks 651 to slide towards each other to clamp the ends of the stator body 5, and then the second cylinder 63 drives the push plate 64 to slide on the support seat, so that the arc block 61 contacts and clamps the stator body 5, so that the stator body 5 is fixed;

[0081] S03, the first cylinder 2 drives the support cover 32 to slide axially downward through the extrusion rod 22. During the sliding process, the adjustment rod 33 will contact the bearing 7 on the stator body 5 in advance. Under the action of the adjustment rod 33, the support cover 32 will be slightly offset, thereby improving the assembly coaxiality of the stator body 5 and the rotor body 4, and then the abutting portion 341 of the clamping block 34 pushes the stator body 5 to be assembled on the stator body 5;

[0082] S04, the first cylinder 2 retracts to separate the clamping block 34 from the rotor body 4, and then the second cylinder 63 retracts to disassemble the assembled stator body 5 and rotor body 4.

[0083] The technical solution of the present invention provides a solution that is significantly different from the prior art to address the technical problem that the prior art solution is too single. The parts not involved in the technical solution of this application are the same as the prior art or can be implemented by using the prior art and will not be described in detail.
