[0002] The rotor is the core moving component of a rotating electric motor, responsible for converting electromagnetic energy into mechanical energy. Its performance directly determines the motor's efficiency, power density, and operational stability. Rotors are typically impregnated with varnish. This impregnation fills the gaps and air layers in the coils, and after curing, forms a continuous and smooth varnish film on the surface of the impregnated windings and components. It also bonds the windings together as a whole, improving coil insulation and curing structure, and enhancing electrical resistance to moisture and heat, as well as mechanical strength.

[0003] Existing motor rotor impregnation equipment requires workers to manually reverse or not reverse the motor rotor during impregnation to control the rotor's direction and ensure uniform coating of paint. However, manual operation may lead to inconsistencies, such as differences in the number of reversals and time control during operation, which in turn affects the uniformity of the paint film.

[0004] Therefore, there is an urgent need for a motor rotor impregnation device to solve the above-mentioned technical problems. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Example 1:

[0030] Reference Figures 1 to 4 This embodiment discloses a motor rotor impregnation device, including a housing 1 and a fixing frame 3. The fixing frame 3 is disposed inside the housing 1 and is immersed in the paint bucket 2. The paint bucket 2 is disposed in the lower inner part of the housing 1.

[0031] A rotating frame 4 is rotatably connected to the inner side of the fixed frame 3. A drive assembly 6 is driven to the top of the rotating frame 4. The drive assembly 6 drives the rotating frame 4 to rotate. The axis of the rotating frame 4 is perpendicular to the horizontal plane. A motor rotor 5 is detachably connected to the inner circumferential side of the rotating frame 4, and the axis of the motor rotor 5 is parallel to the axis of the rotating frame 4. The drive assembly 6 includes a mounting base 601, which is fixed to the upper part of the rotating frame 4. A drive motor 602 is mounted on the mounting base 601, and the output shaft of the drive motor 602 is shaft-connected to the rotating frame 4. The drive motor 602 is a forward and reverse motor. This embodiment does not limit the type of motor; any commercially available motor that can achieve forward and reverse rotation can be used in this embodiment. This embodiment will not elaborate on this aspect.

[0032] During use, the drive motor 602 is turned on, driving the rotating frame 4 to rotate. The uniformity of the paint film is controlled by controlling the number of forward and reverse rotations of the drive motor 602. By driving the rotating frame 4 to rotate automatically, the multiple motor rotors 5 fixed on it can change direction evenly during the paint immersion process, thereby ensuring that the paint fully covers the surface of each rotor. This effectively avoids the problem of uneven paint film caused by inconsistent control of the number of reversals and time in traditional manual operation.

[0033] Example 2:

[0034] like Figure 3 , 4As shown, the difference between this embodiment and the above embodiment is that the bottom of the rotating frame 4 is provided with a lower fixing structure 7, which includes a lower fixing seat 701. The bottom of the lower fixing seat 701 is detachably connected to the rotating frame 4 by a lower fixing bolt 702, and the top surface of the lower fixing seat 701 is provided with a lower fixing groove 703. The top of the rotating frame 4 is provided with an upper fixing structure 8, which includes an upper fixing seat 801. The upper fixing seat 801 is detachably connected to the rotating frame 4 by an upper fixing bolt 802. A slide cylinder 803 is slidably sleeved on the lower outer side of the upper fixing seat 801. A positioning seat 804 is axially connected to the bottom end of the slide cylinder 803. A spring 805 is fixed between the positioning seat 804 and the upper fixing seat 801. The spring 805 is located inside the slide cylinder 803. The bottom surface of the positioning seat 804 is provided with an upper fixing groove 807. The motor rotor 5 is detachably connected between the corresponding lower fixing groove 703 and upper fixing groove 807.

[0035] The upper fixing structure 8 and the lower fixing structure 7 are detachably connected to fix the position of the motor rotor 5. This not only makes operation simple and quick but also ensures that the motor rotor 5 remains stable during the paint impregnation process, avoiding uneven paint film caused by shaking or positional displacement. The cooperation between the lower fixing groove 703 and the upper fixing groove 807 positions the motor rotor 5, while the spring 805 and slide 803 provide appropriate buffering force, making the fixation more secure and preventing damage to the motor rotor 5. Furthermore, the upper fixing structure 8 and the lower fixing structure 7 allow for quick replacement of motor rotors 5 of different specifications, improving the adaptability and production efficiency of the equipment while reducing the complexity of manual operation, providing strong assurance for the consistency and reliability of the paint impregnation process.

[0036] A protective cover 806 is provided between the upper fixed seat 801 and the slide cylinder 803. By providing the protective cover 806, paint can be effectively prevented from entering the internal structure between the upper fixed seat 801 and the slide cylinder 803, and the solidification of the paint can be avoided from hindering the movement of the spring 805 and the slide cylinder 803, thereby ensuring the long-term stability and reliability of the upper fixed structure 8.

[0037] A positioning pin 808 is fixedly attached to the upper wall of the upper fixing groove 807, and the positioning pin 808 mates with the center hole of the end shaft of the motor rotor 5. By setting the positioning pin 808 on the upper wall of the upper fixing groove 807 and mates it with the center hole of the end shaft of the motor rotor 5, precise positioning and stable clamping of the motor rotor 5 can be achieved. This effectively prevents the motor rotor 5 from shifting or rotating during the paint impregnation process, ensures the uniformity of paint film coverage, simplifies the installation and disassembly process of the motor rotor 5, and improves production efficiency.

[0038] The upper fixing groove 807 has a chamfer 809 on its groove edge. By setting the chamfer 809 on the groove edge of the upper fixing groove 807, the wear or damage caused to the groove edge and the surface of the motor rotor 5 during the installation and disassembly of the motor rotor 5 can be effectively reduced. In addition, the chamfer 809 can guide the motor rotor 5 to enter the upper fixing groove 807 more smoothly, reducing the assembly difficulty.

[0039] Example 3:

[0040] like Figure 2 As shown, the difference between this embodiment and the above embodiment is that the top surface of the fixing frame 3 is provided with a height control component 9, and the height control component 9 is located between the top surface of the fixing frame 3 and the outer shell 1;

[0041] The height control assembly 9 includes a base plate 901 and a top plate 905. The base plate 901 is mounted on the top surface of the mounting frame 3, and the top plate 905 is fixed to the inner wall of the housing 1.

[0042] A first support arm 902 and a second support arm 903 are provided between the base plate 901 and the top plate 905. The first support arm 902 and the second support arm 903 are rotatably connected in the middle and cross to form an X shape. One end of the first support arm 902 is slidably connected to the base plate 901 and the other end is rotatably connected to the top plate 905. One end of the second support arm 903 is rotatably connected to the base plate 901 and the other end is slidably connected to the top plate 905. A drive cylinder 904 is rotatably connected to the bottom surface of the top plate 905. The drive end of the drive cylinder 904 is rotatably connected to the upper middle part of the first support arm 902.

[0043] During use, the height is controlled by opening and closing the drive cylinder 904. Since the top plate 905 is fixedly connected to the outer casing 1, the immersion height of the motor rotor 5 can be controlled by adjusting the height of the height control component 9. This not only adapts to the height requirements of motor rotors 5 of different specifications and ensures the consistency of the immersion process, but also improves the flexibility and applicability of the equipment.

They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0045] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
