It is a device used to achieve the conversion between electrical energy and mechanical energy, and between mechanical energy and electrical energy. During the processing, assembly, and fitting of the stator or rotor, some impurities such as dust will be generated on the product surface, and the surface needs to be cleaned to meet the required cleanliness requirements.

[0003] Referring to a stator and rotor surface automatic cleaning device disclosed in a patent application with the publication number CN214235368U, which includes an installation frame and at least a pair of dust suction components; at least a pair of lower cavities are provided on the installation frame, and the lower cavities are communicated with the dust suction components through a dust guide pipe assembly; a placement plate is provided in each lower cavity, and the placement plate is installed at the output end of a rotating mechanism, and the rotating mechanism is installed below the installation frame; a plurality of installation brackets are provided on the installation frame near the lower cavity, and an installation plate is connected to the plurality of installation brackets, and at least a pair of telescopic mechanisms are provided on the installation plate.

It also includes:

[0064] A plurality of placement rings 2 for placing stators, and the plurality of placement rings 2 are all arranged on the top of the placement plate 103.

[0067] During specific implementation, a plurality of stators are sequentially placed on the tops of the plurality of placement rings 2; then the stator is pushed by the inner cleaning mechanism to make the stator coincide with the center of the placement ring 2, and the lifting disc plate 6 is driven to move by the lifting member to press down the stator by the inner cleaning mechanism; when the stator pushes the placement ring 2 to descend, the outer cleaning mechanism sweeps the outside of the stator, and then the inner cleaning structure is driven by the lifting member to clean the inside of the stator, and the cleaning is synchronously carried out by the cleaning liquid in the cleaning tank. By the cooperation of the outer cleaning mechanism, the inner cleaning mechanism and the cleaning liquid inside the cleaning tank, the cleaning effect of the stator is improved.

[0068] Embodiment 2: The outer cleaning component includes:

[0069] An annular frame 3, the annular frame 3 is arranged outside the placement ring 2, and a plurality of sliding blocks 301 are slidably connected to the inside of the annular frame 3. A fixing plate 302 is fixedly connected to the top of each of the plurality of sliding blocks 301;

[0070] A wiping plate 305 arranged on one side of the fixing plate 302. A brush is arranged on the side of the wiping plate 305 close to the placement ring 2. An outer threaded rod 304 is fixedly connected to the other side of the wiping plate 305. A second telescopic rod 306 is fixedly connected between the fixing plate 302 and the wiping plate 305;

The internal-threaded cylinder 303 penetrates through the fixing plate 302 and is rotatably connected to the fixing plate 302. One end of the internal-threaded cylinder 303 is fixedly connected to a bevel gear 307.

[0072] The driving assembly includes:

[0073] Second racks 401 corresponding to the multiple first racks 201 one by one. The multiple second racks 401 are all fixedly connected to the bottom of the annular frame 3, and the multiple second racks 401 all penetrate through the placing plate 103 and are slidably connected to the placing plate 103;

[0074] Multiple first gears 402. The multiple first gears 402 are respectively arranged between the multiple second racks 401 and the first racks 201, and are meshed with the second racks 401 and the first racks 201, and the multiple first gears 402 are rotatably connected to the placing plate 103;

[0075] A limiting cylinder 405 fixedly connected to the top of the placing plate 103, and a spiral groove 4051 is formed inside the limiting cylinder 405;

[0076] A rotating ring 403 arranged inside the limiting cylinder 405. A sliding shaft is fixedly connected to the outside of the rotating ring 403. The sliding shaft extends into the spiral groove 4051 formed on the outside of the limiting cylinder 405. Multiple connecting support plates 404 are fixedly connected to the top of the rotating ring 403, and the multiple connecting support plates 404 are respectively fixedly connected to the multiple fixing plates 302;

[0077] A bevel gear disk 308. The bevel gear disk 308 is meshed with the multiple bevel gears 307, and the bevel gear disk 308 is rotatably connected to the tops of the multiple rotating rings 403.

[0078] During specific implementation, when the stator is placed on the top of the placing ring 2, the lifting member can be used to drive the lifting disk plate 6 to descend. The internal cleaning mechanism on the lifting disk plate 6 is located above the stator and presses down on the stator, causing the stator to push the placing ring 2 to descend. When the placing ring 2 descends, the first rack 201 fixedly connected to the bottom of the placing ring 2 passes through the placing plate 103. The first rack 201 drives the second rack 401 to move in the opposite direction through meshing with the first gear 402, causing the second rack 401 to rise. When the second rack 401 rises, the wiping plate 305 on the top of the annular frame 3 contacts and rises with the outside of the stator, thereby quickly cleaning the outside of the stator;

[0079] When the wiping plate 305 contacts the outer side of the stator, in order to improve the cleaning effect of multiple wiping plates 305, when the annular frame 3 rises, it drives the multiple sliding blocks 301 connected inside it to rise. And the outer side of the fixing plate 302 at the top of the sliding block 301 is fixedly connected with a connecting support plate 404. The bottoms of the multiple connecting support plates 404 are fixedly connected with a rotating ring 403. And the sliding shaft on the outer side of the rotating ring 403 extends to the spiral groove 4051 opened on the outer side of the limiting cylinder 405, so that the rotating ring 403 spirally rises around the spiral groove 4051, thereby driving the multiple connecting support plates 404 to rotate, enabling the connecting support plates 404 to drive the fixing plate 302 to rotate, and thus enabling the wiping plate 305 to rotate annularly around the stator, thereby improving the cleaning effect on the stator;

[0080] When dealing with stators of different sizes, by rotating the bevel gear disk 308, the bevel gear disk 308 drives the multiple meshing bevel gears 307 to rotate, and the bevel gears 307 drive the fixedly connected internal thread cylinder 303 to rotate, so that the external threaded rod 304 threadedly connected inside the internal thread cylinder 303 moves under the limitation of the second telescopic rod 306, thereby making adjustments according to stators of different sizes.

[0081] In this embodiment: A metal ring 205 is fixedly connected to the top of the placing plate 103. An actuating switch 204 for controlling the energization of the placing ring 2 is arranged inside the metal ring 205. The actuating switch 204 is fixedly connected to the top of the placing plate 103. When the placing ring 2 descends and touches the actuating switch 204, after the placing ring 2 is energized, it magnetically adsorbs with the metal ring 205 and the stator, and is used for magnetically fixing the stator.

[0082] During specific implementation, when the placing ring 2 descends, when the placing ring 2 contacts the metal ring 205, it contacts the actuating switch 204, causing the placing ring 2 to be energized and generate magnetism. At this time, the placing ring 2 magnetically adsorbs with the metal ring 205 and adsorbs the stator, ensuring that the stator is in a stable state, facilitating the subsequent cleaning of the inner side of the stator. And later, by cutting off the power supply of the placing ring 2, the elastic member at the bottom of the placing ring 2 can push the placing ring 2 to rise, and the outer cleaning mechanism cleans the placing ring 2, and then the inner cleaning mechanism presses down on the stator for repeated cleaning.

[0083] Embodiment Three: The inner cleaning mechanism includes:

[0084] Multiple limiting plates 7, the multiple limiting plates 7 are arranged annularly around the lifting disk plate 6, and the multiple limiting plates 7 are all fixedly connected with the lifting disk plate 6;

[0086] A sliding plate 801, the sliding plate 801 is arranged inside the groove and is slidably connected with the moving plate 8. One side of the sliding plate 801 is fixedly connected with a support plate 808,

[0087] A second hydraulic rod 802, the telescopic end of the second hydraulic rod 802 is fixedly connected to the sliding plate 801. When the telescopic end of the second hydraulic rod 802 pushes the sliding plate 801 to move, the support plate 808 extends out of the moving plate 8 and inserts into the stator slot.

[0088] A cleaning brush plate 800 fixedly connected to one end of the moving plate 8, and the cleaning brush plate 800 is used for cleaning the inner side of the stator in contact.

[0095] During specific implementation, since a plurality of stator slots for winding are provided on the inner side of the stator, there are attachments inside the stator slots. Due to being inside the stator slots, there are difficulties in cleaning. Therefore, in this solution, when the cleaning brush plate 800 on the moving plate 8 inside the limiting plate 7 contacts the inner side of the stator, for the inside of the stator slots, by starting the second hydraulic rod 802 inside the moving plate 8, the second hydraulic rod 802 is fixedly connected inside the moving plate 8, so that the telescopic end of the second hydraulic rod 802 pushes the sliding plate 801, and the sliding plate 801 pushes the support plate 808 to insert into the stator slots. When the sliding plate 801 moves, the limiting frame 806 fixedly connected to the outside of the sliding plate 801 moves inside the mounting cylinder 804, squeezing the flexible cleaning belt 805 inside the mounting cylinder 804, and injecting the gas inside the flexible cleaning belt 805 into the air cushion 803 outside the support plate 808 through the connecting pipe, so that the air cushion 803 expands inside the stator slots. As the air cushion 803 expands, the air cushion 803 pushes the flexible cleaning belt 805 on the outside to contact the inner wall of the stator slots, avoiding cleaning dead corners.

[0099] During specific implementation, by starting the lifting motor 603 inside the mounting cover 601, the output shaft of the lifting motor 603 drives the fourth gear 602 to rotate. Since the fourth gear 602 is meshed with the double-tooth plate 5, the lifting disk plate 6 can be pushed to rise, so that the flexible cleaning belt 805 attached to the inner wall of the positioning slot rises, thereby achieving full cleaning of the inner wall of the positioning slot.

[0100] In this embodiment: A connecting ring 701 is provided at the top of the lifting disk plate 6.
