Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing equipment technology, and in particular to a motor assembly device. Background Technology

[0002] An electric motor is a key power device that converts electrical energy into mechanical energy, widely used in industrial manufacturing, home appliances, transportation, new energy, and many other fields. Depending on their working principle and application, electric motors can be classified into various types, such as DC motors, AC motors, stepper motors, and servo motors. Although their structures differ, they generally consist of core components such as a stator, rotor, end caps, bearings, and housing. The assembly quality of an electric motor directly affects its operating efficiency, vibration and noise levels, service life, and overall performance. Therefore, high-precision and high-efficiency assembly processes are crucial in the motor manufacturing process. In this process, motor assembly equipment, as specialized equipment for achieving precise positioning, pressing, and fastening of components, plays a vital role in ensuring assembly consistency, reducing manual labor intensity, and improving the level of production automation.

[0003] Utility model patent CN216794803U discloses an auxiliary assembly device for motors. This device achieves rapid positioning of the motor housing and pressing of the housing cover by setting a mold cavity on the base that is adapted to a specific motor housing, and cooperating with a positioning guide shaft and a pressure block that can move up and down. This effectively improves assembly efficiency and quality and reduces the labor intensity of operators.

[0004] However, the mold cavity of this device is a fixed structure, and its size and shape are only suitable for motor housings of a specific specification. When the production line needs to switch to other models or sizes of motor products, the entire mold cavity assembly that matches it must be replaced. This not only consumes time and affects the cycle time, but also requires the company to equip multiple dedicated mold cavities for different motor models, significantly increasing the economic cost of equipment manufacturing and maintenance. Frequent disassembly and assembly of the mold cavity may also introduce positioning reference deviations, affecting the coaxiality of pressing, and thus leading to quality problems such as bearing damage or rotor rubbing.

[0005] Therefore, to address the shortcomings of existing technologies, we urgently need a motor assembly device to solve this problem. This new type of equipment should significantly improve the adaptability and rapid adjustment performance of motor housings of different specifications, while better meeting the modern motor manufacturing demands for high flexibility, high efficiency, and low cost, providing strong support for the intelligent and flexible development of the motor industry. Utility Model Content

[0006] The purpose of this invention is to provide a motor assembly device that solves the problem in the prior art where the mold cavity is a fixed structure, and its size and shape are only suitable for a specific specification of motor housing. When the production line needs to switch to other models or sizes of motor products, the entire matching mold cavity assembly must be replaced, which is not only time-consuming and affects the cycle time, but also requires companies to equip multiple dedicated mold cavities for different motor models, significantly increasing the economic costs of equipment manufacturing and maintenance.

[0007] To achieve the above objectives, this utility model provides a motor assembly device, including a base and a support plate. The support plate is fixedly connected to the top center of the base, and an mounting block is provided on the top of the support plate. The mounting block is connected to the top of the base through a lifting module.

[0008] The top two sides of the support plate are provided with movable plates. The two movable plates are movably connected to the top of the support plate through a bidirectional synchronous moving structure. The top of the movable plate is connected to a central column. The outer ring of the central column is provided with several clamping plates. The clamping plates are rotatably connected to the outer ring of the central column through a rotating structure. The top of the rotating structure is provided with a positioning structure that is detachably connected to the top of the central column. Each of the clamping plates has a clamping groove with a different diameter on one side.

[0009] The top of the support plate is provided with a sliding groove, and the bottom of the movable plate is fixedly connected with a movable block that slides and engages with the inside of the sliding groove.

[0010] The rotating structure includes a rotating ring that rotates in conjunction with the central column, and a plurality of clamping plates arranged in a ring along the circumference of the rotating ring, with each clamping plate being fixedly connected to the side wall of the rotating ring via a connecting rod.

[0011] The bidirectional synchronous moving structure includes a lead screw rotatably connected inside the slide groove and a drive motor installed at one end of the bearing plate. The output shaft of the drive motor is connected to the end of the lead screw, and the lead screw is threadedly engaged with the moving block.

[0012] The top of the central column is fixedly connected to a pressure plate, and the positioning structure includes a positioning screw with one end threaded through the pressure plate. The top of the rotating ring is provided with several positioning holes that are adapted to the positioning screw.

[0013] The rotating ring has a handle on one side, which is made of metal and one end of the handle is fixedly connected to the side wall of the rotating ring.

[0014] This utility model discloses a motor assembly device. By incorporating a laterally movable plate on a support plate, along with a central column and clamping plates with slots of various diameters, it effectively solves the problem in existing technologies where fixed mold cavities prevent adaptation to various motor housing sizes. This avoids the cumbersome operation, high costs, and positioning deviation risks associated with frequent mold cavity replacements. The bidirectional synchronous movement structure ensures synchronized movement of the two movable plates, allowing for symmetrical adjustment of the clamping plates on both sides, guaranteeing coaxiality during motor housing installation and reducing assembly stress or bearing damage caused by eccentricity. Multiple slots of different diameters on the clamping plates, combined with the lateral adjustment capability of the movable plates, significantly improve the device's versatility and adaptability to motor housings of different outer diameters, meeting the needs of flexible production with multiple varieties and small batches. The lifting module adjusts the height of the mounting blocks, further enhancing adaptability to motors with different axial dimensions. The positioning structure is detachably connected to the top of the central column, facilitating the installation and maintenance of the clamping plates while providing axial constraint and improving stability during assembly.

[0022] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0023] Example 1

[0024] Please see Figure 1-5 As shown, a motor assembly device of this embodiment includes a base 1 and a support plate 2. The support plate 2 is fixedly connected to the top center of the base 1. An mounting block 4 is provided on the top of the support plate 2. The mounting block 4 is connected to the top of the base 1 through a lifting module 3.

[0025] Movable plates 15 are provided on both sides of the top of the support plate 2. The two movable plates 15 are movably connected to the top of the support plate 2 through a bidirectional synchronous moving structure. A central column 16 is connected to the top of the movable plate 15. Several clamping plates 5 are provided on the outer ring of the central column 16. The clamping plates 5 are rotatably connected to the outer ring of the central column 16 through a rotating structure. The top of the rotating structure is provided with a positioning structure that is detachably connected to the top of the central column 16. Each of the clamping plates 5 has a clamping groove of different diameter on one side.

[0026] Workflow: When using this motor assembly device, first fix the base 1 to the assembly station. The support plate 2 is located at the top center of the base 1 and kept horizontal and stable. The mounting block 4 is connected to the base 1 through the lifting module 3, and its height can be adjusted according to different motor models. When it is necessary to assemble a motor housing of a certain specification, there is no need to replace the overall mold cavity. Instead, the two moving plates 15 are driven by the bidirectional synchronous moving structure to move synchronously towards or away from each other in the lateral direction on the top of the support plate 2, thereby adjusting the distance between the two central columns 16. Each moving plate 15 has a central column 16 fixed on its top. Several clamping plates 5 are hinged to the outer ring of the central column 16 through a rotating structure. Multiple clamping slots of different diameters are opened on one side of the clamping plates 5. The operator can select according to the outer diameter of the motor housing to be installed. The appropriate clamping slots are oriented towards the center position; by adjusting the positions of the two moving plates 15, the appropriate clamping slots on the two clamping plates 5 are aligned, and then the motor housing is placed between the two sets of clamping plates 5, so that its two ends are respectively embedded in the corresponding clamping slots to achieve quick positioning and clamping; subsequently, the positioning structure is installed on the top of the central column 16 to axially limit the entire clamping plate 5 and prevent it from axially moving during assembly; after the installation of the internal components of the motor is completed, the mounting block 4 can be raised by the lifting module 3 to assist in the end cover pressing or other assembly operations; when changing to a motor of different specifications, it is only necessary to readjust the position of the moving plate 15 through the bidirectional synchronous moving structure and select the corresponding diameter clamping slot on the clamping plate 5 to adapt to the new size housing, without disassembling the entire positioning assembly.

[0027] Example 2

[0028] Please see Figure 1-5 As shown in this embodiment, a motor assembly device has a slide groove 9 on the top of the support plate 2, and a moving block 14 that slides and engages with the inside of the slide groove 9 is fixedly connected to the bottom of the moving plate 15. Specifically, by using the slide groove 9 on the top of the support plate 2 and the moving block 14 that slides and engages with the inside of the slide groove 9 to fix the bottom of the moving plate 15, when the bidirectional synchronous moving structure drives the moving plate 15 to move laterally, the moving block 14 slides smoothly along the slide groove 9, which achieves the effect of providing stable guidance and reducing frictional resistance, ensuring that the moving plate 15 can be accurately positioned, and improving the accuracy and stability of the motor housing clamping.

[0029] The bidirectional synchronous movement structure includes a lead screw 10 rotatably connected inside the slide groove 9 and a drive motor 7 mounted at one end of the support plate 2. The output shaft of the drive motor 7 is connected to the end of the lead screw 10, and the lead screw 10 is threadedly engaged with the moving block 14. Specifically, by setting up the bidirectional synchronous movement structure, which includes a lead screw 10 rotatably connected inside the slide groove 9 and a drive motor 7 mounted at one end of the support plate 2, with the output shaft of the drive motor 7 connected to the end of the lead screw 10 and the lead screw 10 threadedly engaged with the moving block 14, starting the drive motor 7 causes its output shaft to drive the lead screw 10 to rotate, thereby causing the moving block 14 threadedly engaged with it to move horizontally along the slide groove 9. This achieves the effect of synchronously moving the two moving plates 15 towards or away from each other, simplifying the adjustment process and improving work efficiency and accuracy.

[0030] Example 3

[0031] Please see Figure 1-5 As shown, in this embodiment, a motor assembly device includes a rotating structure comprising a rotating ring 6 that rotatably engages with a central column 16, and a plurality of clamping plates 5 arranged in a ring along the circumference of the rotating ring 6. Each clamping plate 5 is fixedly connected to the side wall of the rotating ring 6 via a connecting rod 13. Specifically, by including a rotating ring 6 that rotatably engages with a central column 16, and a plurality of clamping plates 5 arranged in a ring along the circumference of the rotating ring 6 and fixedly connected to the side wall of the rotating ring 6 via a connecting rod 13, the operator can adjust the angle of each clamping plate 5 by rotating the rotating ring 6, so that the clamping groove of a suitable diameter is aligned with the motor housing to be assembled. This achieves the effect of flexibly adjusting the position of the clamping plates 5 to adapt to motor housings of different sizes, improving the versatility and flexibility of the device.

[0032] A pressure plate 8 is fixedly connected to the top of the central column 16. The positioning structure includes a positioning screw 17 with one end threaded through the pressure plate 8. The top of the rotating ring 6 is provided with several positioning holes 12 that are adapted to the positioning screw 17. Specifically, by fixing the pressure plate 8 to the top of the central column 16, and providing a positioning structure including a positioning screw 17 with one end threaded through the pressure plate 8, and providing several positioning holes 12 that are adapted to the positioning screw 17 on the top of the rotating ring 6, after the angle of the clamping plate 5 is adjusted, the positioning screw 17 is screwed into the corresponding positioning hole 12 to axially limit the rotating ring 6, thereby preventing the rotating ring 6 from rotating or loosening accidentally during assembly and enhancing the stability and reliability of the clamping system.

[0033] A handle 11 is provided on one side of the rotating ring 6. The handle 11 is made of metal and one end of the handle 11 is fixedly connected to the side wall of the rotating ring 6. Specifically, by providing a handle 11 on one side of the rotating ring 6, and by making the handle 11 of metal and fixing it to the side wall of the rotating ring 6, the operator can manually rotate the rotating ring 6 by holding the handle 11, which facilitates quick and intuitive adjustment of the position of the clamp 5. This improves the ease and comfort of operation, and is especially suitable for small-batch production scenarios with frequent changes in specifications, reducing labor intensity and improving work efficiency.

[0034] When using this motor assembly device, firstly, the base 1 is securely installed at the assembly station, and the bearing plate 2 is fixed at the top center of the base 1 to ensure the overall structure is horizontally stable. The mounting block 4 is connected to the base 1 through the lifting module 3, and its vertical position can be adjusted according to the height requirements of different motor models. When it is necessary to assemble a motor housing of a specific specification, the drive motor 7 installed at one end of the bearing plate 2 is started, and its output shaft drives the lead screw 10 to rotate. The lead screw 10 is threadedly engaged with the moving block 14, and the moving block 14 is fixed at the bottom of the moving plate 15 and embedded in the slide groove 9 at the top of the bearing plate 2. As the lead screw 10 rotates, the two moving plates 15 move synchronously towards or away from each other along the slide groove 9 under the drive of the bidirectional synchronous moving structure, thereby precisely adjusting the distance between the two central columns 16. A central column 16 is fixedly connected to the top of each moving plate 15, and a rotating ring 6 is provided on the outer ring of the central column 16. The rotating ring 6 can rotate freely around the central column 16. Several clamping plates 5 are connected in a ring shape by the connecting rod 13. The array is fixed in the circumferential direction of the rotating ring 6. Multiple clamping slots of different diameters are provided on one side of the clamping plate 5. The operator manually rotates the rotating ring 6 by holding the metal handle 11 fixed to the side wall of the rotating ring 6, selecting a clamping slot of appropriate diameter facing the center. After the angle of the clamping plate 5 is adjusted, the positioning screw 17 is screwed into the upper end of the pressure plate 8. The pressure plate 8 is fixed to the top of the central column 16, and the lower end of the positioning screw 17 is inserted into the corresponding positioning hole 12 at the top of the rotating ring 6, achieving axial locking of the rotating ring 6 and preventing it from loosening or shifting during assembly. Subsequently, both ends of the motor housing are embedded into the corresponding clamping slots of the clamping plates 5 on both sides, completing the positioning and clamping. During subsequent processes such as end cap pressing, the mounting block 4 can be driven upward by the lifting module 3 to assist in completing the pressing action. When changing to a different model of motor, simply reverse the above process, readjust the position of the moving plate 15, and switch the clamping slots on the clamping plate 5 to quickly adapt to the new specifications without replacing the entire mold cavity assembly.

[0035] This motor assembly device, through the cooperation of base 1, bearing plate 2, lifting module 3, and mounting block 4, achieves adaptive adjustment for motors of different heights, improving assembly flexibility. The sliding engagement between the top groove 9 of bearing plate 2 and the bottom moving block 14 of moving plate 15 provides stable lateral guidance for moving plate 15, reducing swaying and friction during movement. The bidirectional synchronous movement structure, driven by drive motor 7 to rotate lead screw 10, moves moving block 14 along groove 9, achieving synchronous adjustment of the two moving plates 15 and ensuring the stability of both sides. The symmetry and coaxiality of the center column 16 prevent assembly stress caused by eccentricity. A rotatable rotating ring 6 is set on the outer ring of the center column 16, and the clamping plate 5 is fixed to it by the connecting rod 13. With the help of the handle 11, different diameter clamping slots can be manually rotated to switch, so that the device can be adapted to motor housings of various outer diameters, which significantly improves versatility and changeover efficiency. The pressure plate 8 is fixed to the top of the center column 16, and with the help of the detachable positioning screw 17 inserted into the positioning hole 12 of the rotating ring 6, a reliable axial locking of the rotating ring 6 is achieved, which enhances the stability of the clamping process.

[0036] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application.
