Abstract

The application provides a high-precision flexible special motor stator-rotor assembling mechanism, which mainly comprises a vertical plate, sliding rails, sliding blocks and a base. The mechanism is reasonable in structure, reliable in operation and good in safety. By pushing the sliding blocks, the motor rotors installed on the sliding blocks can smoothly enter the motor stators installed on the vertical plate, so that the uneven air gap caused by the coaxiality deviation of the stator and the rotor in the previous motor assembling process can be avoided, and problems such as the adsorption of the stator and the rotor or the damage of the sealing ring can be avoided. By replacing the vertical plate and the sliding blocks, the applicability of multiple models of motors can be realized, the motor assembling quality is improved, the flexible design of the shared assembling mechanism for multiple models of motors is realized, and the cost is saved.

Description

Technical Field

[0001] This invention belongs to the field of motor assembly technology, specifically relating to a high-precision flexible special motor stator and rotor assembly mechanism. Background Technology

[0002] When a permanent magnet synchronous motor operates, energy is transferred in the form of electromagnetic energy through the air gap between the stator and rotor. The corresponding power is called electromagnetic power. Therefore, electromagnetic power is closely related to the main dimensions of the motor. The air gap is to ensure that the rotor can rotate freely within the stator cavity. The size of the air gap determines the motor's performance and operational reliability. An excessively large air gap will increase magnetic reluctance, leading to increased excitation losses and a corresponding increase in excitation current, resulting in a decrease in the motor's power factor and reduced performance. To reduce excitation current and improve the power factor, the air gap should be minimized. However, an excessively small air gap will increase the air gap harmonic magnetic field, increasing stray losses and noise, and simultaneously reducing both maximum torque and starting torque. Furthermore, a too-small air gap can easily cause rotor-stator rubbing during operation, leading to rotor rubbing and reducing the motor's reliability and safety. Additionally, due to the magnetic attraction between the stator and rotor, an excessively small air gap can cause assembly difficulties.

[0003] In the core process of motor manufacturing, the precise assembly of the stator and rotor is crucial to ensuring the motor's efficient and stable operation. The stator, as the stationary part of the motor, generates a rotating magnetic field through electromagnetic induction; the rotor, as the rotating part, rotates under the influence of this magnetic field, converting electrical energy into mechanical energy. The precision of the stator and rotor assembly process directly affects motor performance, air gap size, magnetic flux path, and energy conversion efficiency. Even minute assembly errors can lead to performance degradation or even motor damage. Therefore, the stator-rotor assembly mechanism plays a vital role in ensuring assembly precision, consistency, and reliability, thereby improving production efficiency and product quality. Summary of the Invention

[0004] (a) Technical problems to be solved This invention proposes a high-precision flexible special motor stator and rotor assembly mechanism to solve the technical problem of how to improve production efficiency and product quality.

[0005] (II) Technical Solution To address the aforementioned technical problems, this invention proposes a high-precision flexible special motor stator-rotor assembly mechanism. This mechanism includes a vertical plate, a slide rail, a slider, and a base. The bottom of the vertical plate has multiple positioning holes, and the vertical plate is fixed to one end of the top of the base after passing through these holes. A stator assembly mounting hole is located at the center of the vertical plate for mounting the motor stator. The slide rail is fixed to the other end of the top of the base, and the slider is mounted on the slide rail and can slide along it. A rotor assembly mounting hole is located at the center of the slider for mounting the motor rotor. By pushing the slider, the motor rotor mounted on the slider can enter the motor stator mounted on the vertical plate.

[0006] Furthermore, a fixing device for fixing the motor stator is provided on the outer periphery of the stator assembly mounting hole.

[0007] Furthermore, a limit device is provided at the end of the slide rail to limit the sliding of the slider.

[0008] Furthermore, the bottom of the base is equipped with adjustable feet. By adjusting the height of the adjustable feet, the base can be kept horizontal, thereby ensuring that the motor rotor assembly mounting hole located at the center of the slider and the stator assembly mounting hole located at the center of the vertical plate are horizontal.

[0009] Furthermore, by adjusting the positioning holes at the bottom of the vertical plate, the coaxiality tolerance between the motor rotor assembly mounting holes on the slider and the stator assembly mounting holes on the vertical plate can be ensured to be no more than 0.03 mm.

[0010] Furthermore, the upright plate and slider can be replaced according to the model of the assembled motor.

[0011] (III) Beneficial Effects This invention proposes a high-precision, flexible special motor stator-rotor assembly mechanism, mainly comprising a vertical plate, a slide rail, a slider, and a base. This mechanism features a reasonable structure, reliable operation, and good safety. By pushing the slider, the motor rotor mounted on the slider smoothly enters the motor stator mounted on the vertical plate, avoiding problems such as uneven air gap caused by stator-rotor coaxiality deviations, and even stator-rotor adhesion or seal damage that occur during traditional motor assembly processes. By replacing the vertical plate and slider, it can be applied to multiple motor models, improving motor assembly quality and enabling a flexible design for multiple motor models to share the same assembly mechanism, thus saving costs. Attached Figure Description

[0012] Figure 1 This is a schematic diagram of the overall structure of the high-precision flexible special motor stator and rotor assembly mechanism of the present invention. Detailed Implementation

[0013] To make the objectives, contents, and advantages of the present invention clearer, the specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples.

[0014] This embodiment proposes a high-precision flexible special motor stator and rotor assembly mechanism, the overall structure of which is as follows: Figure 1 As shown, it mainly includes a vertical plate 1, a fixing device 2, a slide rail 3, a slider 4, a limiting device 5, adjustable feet 6, and a base 7.

[0015] The bottom of the upright plate 1 has multiple positioning holes. After screws are inserted into the positioning holes, the upright plate 1 is fixed to one end of the top of the base 7. The center of the upright plate 1 has a stator assembly mounting hole for mounting the motor stator. Multiple fixing devices 2 are provided around the stator assembly mounting hole for fixing the motor stator.

[0016] The slide rail 3 is fixed to the other end of the top of the base 7 by screws. The slider 4 is mounted on the slide rail 3 and can slide along the slide rail 3. A limit device 5 is provided at the end of the slide rail 3 to limit the sliding of the slider 4. A rotor assembly mounting hole is provided in the center of the slider 4 for mounting the motor rotor. The coaxiality between the stator and rotor is ensured by the position of the mounting holes on the upright plate 1 and the slider 4.

[0017] By pushing the slider 4, the motor rotor mounted on the slider 4 can smoothly enter the motor stator mounted on the vertical plate 1, avoiding uneven air gap caused by stator-rotor eccentricity during motor assembly, and even problems such as stator-rotor adsorption and seal ring damage during assembly.

[0018] The bottom of the base 7 is equipped with multiple adjustable feet 6. By adjusting the height of the adjustable feet 6, the base 7 can be kept in a horizontal state, thereby ensuring that the motor rotor assembly mounting hole located in the center of the slider 4 and the stator assembly mounting hole located in the center of the vertical plate 1 are in a horizontal state.

[0019] By adjusting the positioning holes at the bottom of the vertical plate 1, the coaxiality form and position tolerance between the motor rotor assembly mounting holes on the slider 4 and the stator assembly mounting holes on the vertical plate 1 can be guaranteed to be no more than 0.03mm. This ensures that the coaxiality error between the motor stator and rotor is within a very small range, thereby guaranteeing the coaxiality accuracy of the stator and rotor assembly and the uniformity of the air gap between the stator and rotor.

[0020] This mechanism is suitable for assembling various types of motors. By replacing the vertical plate 1 and the slider 4, it is possible to assemble various types of motors, thus improving the flexibility and applicability of the device.

[0021] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
