Description

Technical Field

[0001] This utility model relates to the field of motor component assembly technology, specifically to a high-precision motor rotor assembly device. Background Technology

[0002] Stator and rotor assembly refers to the process of assembling the stator and rotor components of a motor in the correct positions and manner. The stator is the stationary part of the motor, typically including the stator core, stator windings, and frame; its main function is to generate a rotating magnetic field. The rotor is the rotating part of the motor, including the rotor core, rotor windings, slip rings, etc. Its main function is to generate electromagnetic torque in the rotating magnetic field, realizing the conversion of electrical energy into mechanical energy. In a motor, the interaction between the stator and rotor is key to achieving this conversion. The stator generates a rotating magnetic field, and the rotor generates an induced electromotive force in this field, which in turn produces electromagnetic torque, driving the rotor to rotate. The input and output of electrical energy are achieved through the cooperation of slip rings and carbon brushes.

[0003] The existing motor rotor assembly equipment has the following shortcomings:

[0004] 1. Most designs assemble the stator and rotor of motors of the same size and specification. When encountering a motor of another size, the dimensions of its stator and rotor change. Since the clamping stroke of the fixture cannot be measured, the assembly requirements of the stator and rotor of motors of different sizes and specifications cannot be met, which reduces the practicality of the device.

[0005] 2. Most of the time, the rotor or stator is fed manually, and the stator and rotor cannot be clamped and fixed synchronously. Then, the rotor is pressed into the stator by a pressure block. The pressing process is cumbersome, time-consuming and labor-intensive, thus reducing the pressing efficiency.

[0006] 3. Manually feeding the rotor cannot guarantee the concentricity of the rotor and stator, resulting in the rotor being unable to be pressed into place with the stator during press fitting. Utility Model Content

[0008] To achieve this objective, the present invention adopts the following technical solution:

Each positioning component is located between one fixed ring and one rotating ring.

[0013] The assembly mechanism is located between the upright plate and the side plate. The assembly mechanism includes a dual-axis motor, two telescopic components and three sliding components. The dual-axis motor is fixed on the outer wall of the side plate. The two telescopic components are symmetrically arranged between the side plate and the sliding plate. The three sliding components are all located on the outer wall of the upright plate. The drive motor and the dual-axis motor are electrically connected to the controller.

[0014] Preferably, the transmission assembly includes a gear and an arc-shaped rack. The gear is fixedly mounted on the output end of the drive motor, and the arc-shaped rack is fixedly mounted on the outer wall of one of the rotating rings away from the dual-shaft motor. The gear and the arc-shaped rack are meshed together.

[0015] Preferably, each positioning component includes four limiting rods, four arc-shaped pressure blocks, four fixing blocks, and four connecting blocks. The four fixing blocks are symmetrically arranged on the rotating ring, and the four connecting blocks are symmetrically arranged on the fixing ring. Each limiting rod is disposed between a fixing block and a connecting block, and one end of the limiting rod is fixedly connected to the fixing block, while the other end is slidably connected to the connecting block. Each arc-shaped pressure block is disposed on a limiting rod.

[0016] Preferably, each telescopic component includes a fixed seat, a connecting seat, a rotating shaft, a first connecting rod, and a second connecting rod. Both the fixed seat and the connecting seat have grooves for the first and second connecting rods to rotate. The rotating shaft is fixedly mounted on one of the output ends of the dual-axis motor. The fixed seat is fixedly mounted on the outer wall of the side plate, and the rotating shaft is rotatably connected to the fixed seat. The first connecting rod is fixedly mounted on the outer wall of the rotating shaft near the groove. The connecting seat is fixedly mounted on the outer wall of the slide plate. The second connecting rod is hinged in the groove located on the connecting seat, and the end of the first connecting rod away from the rotating shaft is hinged to the end of the second connecting rod away from the groove.

[0017] Preferably, each sliding component includes a guide rail and a slider. The guide rail is fixedly mounted on the outer wall of the upright plate, and the slider is slidably mounted on the guide rail and fixedly connected to the slide plate.

[0018] Preferably, each arc-shaped pressure block is fixedly connected to a limiting rod by bolts.

[0021] The beneficial effects of this utility model are:

[0022] 1. The arc-shaped pressure block of this assembly device is fixedly connected to the limit rod by bolts. This allows for the clamping and adjustment of stators and rotors of different sizes by disassembling and replacing arc-shaped pressure blocks of different sizes. This enables the assembly device to meet the assembly requirements of rotors and stators inside motors of different sizes and specifications, thereby improving the practicality of the assembly device.

[0023] 2. This assembly device is designed with a centering mechanism.

[0034] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0035] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of the present invention, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.

[0036] Reference Figures 1 to 6 As shown, a high-precision motor rotor assembly device includes a base plate 1, a vertical plate 2, a side plate 3, a sliding plate 4, and a support plate 5. The vertical plate 2 and the side plate 3 are both fixedly mounted on the top of the base plate 1, and the vertical plate 2 and the side plate 3 are fixedly connected. The sliding plate 4 is slidably mounted on the outer wall of the vertical plate 2, and the support plate 5 is fixedly mounted on the vertical plate 2.

[0037] It also includes a controller, a drive mechanism, a centering mechanism, and an assembly mechanism;

[0038] The drive mechanism is fixedly mounted on the top of the base plate 1. The drive mechanism includes a drive motor 6 and a transmission assembly. The drive motor 6 is fixedly mounted on the top of the base plate 1, and the transmission assembly is located between the drive motor 6 and the support plate 5.

[0039] The centering mechanism is located between the base plate 1 and the upright plate 2. The centering mechanism includes two connecting rods 7, two rotating rings 8, two fixed rings 9, and two positioning components. The two rotating rings 8 are rotatably mounted on the slide plate 4 and the support plate 5, respectively. The two fixed rings 9 are respectively mounted on the inner walls of the two rotating rings 8, and the two rotating rings 8 are rotatably connected to the two fixed rings 9, respectively. The two connecting rods 7 are symmetrically mounted on the rotating rings 8 away from the dual-axis motor 10, and one end of each connecting rod 7 is fixedly connected to one of the rotating rings 8 away from the dual-axis motor 10. The other end of each connecting rod 7 is slidably connected to the other rotating ring 8. Each positioning component is located between one fixed ring 9 and one rotating ring 8.

[0040] The assembly mechanism is located between the upright plate 2 and the side plate 3. The assembly mechanism includes a dual-axis motor 10, two telescopic components and three sliding components. The dual-axis motor 10 is fixed on the outer wall of the side plate 3. The two telescopic components are symmetrically arranged between the side plate 3 and the slide plate 4. The three sliding components are all located on the outer wall of the upright plate 2. The drive motor 6 and the dual-axis motor 10 are electrically connected to the controller.

[0041] Reference Figures 1 to 6 As shown, the transmission assembly includes a gear 11 and an arc-shaped rack 12. The gear 11 is fixedly mounted on the output end of the drive motor 6, and the arc-shaped rack 12 is fixedly mounted on the outer wall of one of the rotating rings 8 away from the dual-axis motor 10. The gear 11 and the arc-shaped rack 12 are meshed together. Before assembling the stator and rotor, the worker first places the stator on the arc-shaped pressure block 14 located below and away from the dual-axis motor 10, and places the rotor on the arc-shaped pressure block 14 located below and close to the dual-axis motor 10. Then, the worker starts the drive motor 6 through the controller. Since the gear 11 is fixedly connected to the output end of the drive motor 6, and the arc-shaped rack 12 is fixedly connected to the rotating ring 8 away from the dual-axis motor 10, and the gear 11 and the arc-shaped rack 12 are meshed together, and the rotating ring 8 is rotatably connected to the fixed ring 9, the gear 11 drives the rotating ring 8 away from the dual-axis motor 10 to rotate.

[0042] Reference Figures 1 to 6As shown, each positioning component includes four limiting rods 13, four arc-shaped pressure blocks 14, four fixing blocks 15, and four connecting blocks 16. The four fixing blocks 15 are symmetrically arranged on the rotating ring 8, and the four connecting blocks 16 are symmetrically arranged on the fixing ring 9. Each limiting rod 13 is positioned between a fixing block 15 and a connecting block 16, with one end of the limiting rod 13 fixedly connected to the fixing block 15 and the other end slidably connected to the connecting block 16. Each arc-shaped pressure block 14 is positioned on a limiting rod 13. When the gear 11 drives the dual-axis motor away from the rotating ring 9, the positioning component is positioned as follows: When the rotating ring 8 of the dual-axis motor 10 rotates, since one end of each of the two connecting rods 7 is fixedly connected to the rotating ring 8 away from the dual-axis motor 10, and the other end of each of the two connecting rods 7 is slidably connected to the rotating ring 8 close to the dual-axis motor 10, the rotating ring 8 away from the dual-axis motor 10 can synchronously drive the rotating ring 8 close to the dual-axis motor 10 to rotate together. Since each connecting block 16 is fixedly connected to the fixed ring 9, each fixed block 15 is fixedly connected to the rotating ring 8, and one end of each limiting rod 13 is fixedly connected to a fixed block 15, each limiting rod 13... The other end of each positioning rod 13 is slidably connected to a connecting block 16, and each arc-shaped pressure block 14 is fixedly connected to a limiting rod 13. Additionally, the base plate 1 and the upright plate 2 are fixedly connected to a fixing ring 9 away from the dual-axis motor 10, and the fixing ring 9 near the dual-axis motor 10 is fixedly connected to the slide plate 4. Two rotating rings 8 are rotatably connected to the support plate 5 and the slide plate 4, respectively. This ensures that when the two rotating rings 8 rotate synchronously, i.e., when one end of the limiting rod 13 slides on the connecting block 16, it will drive the limiting rod 13 to rotate, thus driving the arc-shaped pressure blocks 14 on the limiting rods 13 to rotate. All four move towards the center, thus achieving synchronous clamping of the stator and rotor. Since the size of the arc-shaped pressure block 14 near the dual-axis motor 10 is larger than that of the arc-shaped pressure block 14 away from the dual-axis motor 10, the stator and rotor become coaxial, facilitating their press-fitting. It should be noted that the diameter of the rotor is smaller than that of the stator. Therefore, the size of the arc-shaped pressure block 14 near the dual-axis motor 10 is designed to be larger than that of the arc-shaped pressure block 14 away from the dual-axis motor 10, so that the eight arc-shaped pressure blocks 14 can synchronously clamp the rotor and stator with different diameters, achieving their press-fitting.

[0043] Reference Figures 1 to 6As shown, each telescopic assembly includes a fixed base 17, a connecting base 18, a rotating shaft 19, a first connecting rod 20, and a second connecting rod 21. Both the fixed base 17 and the connecting base 18 have grooves for the first connecting rod 20 and the second connecting rod 21 to rotate. The rotating shaft 19 is fixed to one of the output ends of the dual-axis motor 10. The fixed base 17 is fixed to the outer wall of the side plate 3, and the rotating shaft 19 is rotatably connected to the fixed base 17. The first connecting rod 20 is fixed to the outer wall of the rotating shaft 19 near the groove. The connecting base 18 is fixed to the outer wall of the slide plate 4. The second connecting rod 21 is hinged in the groove located on the connecting base 18, and the first connecting rod 20 is away from the rotating shaft 19. One end is hinged to the end of the second connecting rod 21 away from the groove. When the arc-shaped pressure block 14 on the limiting rod 13 moves to the middle to achieve coaxial clamping of the stator and rotor, the worker starts the dual-axis motor 10 through the controller. Since the rotating shaft 19 is fixedly connected to one of the output ends of the dual-axis motor 10, the first connecting rod 20 is fixedly connected to the rotating shaft 19, the second connecting rod 21 is hinged to the connecting seat 18, and the first connecting rod 20 and the second connecting rod 21 are hinged together, the slide plate 4 is slidably connected to the upright plate 2, so that the first connecting rod 20 and the second connecting rod 21 rotate at the same time, that is, the first connecting rod 20 and the second connecting rod 21 unfold, thereby driving the slide plate 4 to slide towards the end closer to the drive motor 6.

[0044] Reference Figures 1 to 6 As shown, each sliding component includes a guide rail 22 and a slider 23. The guide rail 22 is fixedly mounted on the outer wall of the upright plate 2, and the slider 23 is slidably mounted on the guide rail 22. The slider 23 is fixedly connected to the slide plate 4. When the slide plate 4 slides towards the end closer to the drive motor 6, since the guide rail 22 is fixedly connected to the upright plate 2, the slider 23 is slidably connected to the guide rail 22, and the slide plate 4 is fixedly connected to the slider 23, the slide plate 4 slides on the guide rail 22. Since the rotating ring 8 near the dual-axis motor 10 is rotatably connected to the slide plate 4, and the fixed ring 9 near the dual-axis motor 10 is fixedly connected to the slide plate 4, the connecting block 16 and the fixed block 15 are fixedly connected to the fixed ring 9 and the rotating ring 8, respectively. In addition, one end of the limiting rod 13 is fixedly connected to the fixed block 15, and the other end of the limiting rod 13 is slidably connected to the connecting block 16. The arc-shaped pressure block 14 is fixedly connected to the limiting rod 13, thereby causing the rotor to slide towards the stator under the pushing action of the slide plate 4, thus realizing the press-fitting between the stator and the rotor.

[0045] Reference Figures 1 to 6 As shown, each arc-shaped pressure block 14 is fixedly connected to a limiting rod 13 by bolts. The arc-shaped pressure block 14 and the limiting rod 13 are designed to be fixedly connected by bolts, which makes it easy to replace the arc-shaped pressure block 14 by removing and installing bolts. This allows for the assembly of stators and rotors of different sizes, improving the flexibility of the device.

[0046] Reference Figures 1 to 6As shown, both the upright plate 2 and the base plate 1 are provided with fixing plates 24, and both fixing plates 24 are fixedly connected to one of the fixing rings 9 away from the dual-axis motor 10. Two U-shaped plates 25 are symmetrically arranged on the slide plate 4, and both ends of each U-shaped plate 25 are fixedly connected to the slide plate 4 and the fixing ring 9 near the dual-axis motor 10. The slide plate 4 and the other fixing ring 9 are fixedly connected to both ends of each U-shaped plate 25. The two fixing plates 24 and the two U-shaped plates 25 respectively support and fix the two fixing rings 9, so that when the rotating ring 8 on the two fixing rings 9 rotates, it drives the eight arc-shaped pressure blocks 14 to move closer to each other, thereby clamping the stator and rotor, thus facilitating the rapid assembly of the stator and rotor.

[0047] Reference Figures 1 to 6 As shown, each arc-shaped pressure block 14 is provided with an anti-slip pad 26, and each anti-slip pad 26 is made of rubber material. This increases the friction between the arc-shaped pressure block 14 and the outer wall of the stator or rotor, thereby improving the clamping effect of the device on the stator and rotor. This is beneficial to improving the assembly efficiency of the stator and rotor, preventing the stator and rotor from slipping or shifting during the assembly process, which would affect the assembly effect and thus affect the quality of the motor and improve production efficiency.
