Description

Technical Field

[0001] This utility model belongs to the field of stator processing technology, specifically relating to a stator clamping mechanism for motor stator processing. Background Technology

[0002] In the field of motor manufacturing, the machining quality and precision of the motor stator are crucial to the performance and reliability of the motor. During the stator machining process, the stator needs to be effectively clamped and fixed to ensure smooth machining operations and guarantee machining accuracy.

[0003] Traditional motor stator clamping mechanisms often have many problems in practical applications. Some clamping mechanisms can only clamp from the top or side of the stator in one direction, resulting in uneven force on the stator. This can easily lead to displacement and deformation during processing, thus affecting processing accuracy and product quality.

[0004] In addition, some clamping mechanisms are poorly designed, resulting in poor coordination between their clamping components and an inability to achieve synchronous clamping. This leads to a time difference during the clamping process, further exacerbating the problem of uneven clamping. Moreover, some clamping devices are prone to wear and loosening after long-term use, resulting in unstable clamping force and making it difficult to ensure the stator is firmly fixed during processing.

[0005] To address this, we propose a stator clamping mechanism for motor stator machining. This device achieves multi-point synchronous clamping at the top and sides, ensuring uniform force on the stator during machining, effectively improving machining accuracy and product quality, while also coordinating and synchronizing to increase clamping force. Utility Model Content

[0006] The purpose of this invention is to provide a stator clamping mechanism for motor stator processing. This device achieves multi-point synchronous clamping at the top and sides, ensuring uniform force on the stator during processing, effectively improving processing accuracy and product quality, while also coordinating and synchronizing to increase clamping force.

[0007] The specific technical solution adopted by this utility model is as follows:

[0008] A stator clamping mechanism for motor stator processing includes a chassis, four housings are provided on the top of the chassis, each housing is provided with a rotating component and a through hole, and the rotating component is provided with a first gear, a second gear and a top clamping plate;

[0009] The chassis has a sliding groove, and a sliding component is provided inside the sliding groove. A movable plate that moves inside the through hole is provided on the sliding component. A second meshing tooth that meshes with the second gear is provided on one side of the movable plate, and a side pressing plate is provided on the movable plate.

[0010] Each of the four housings has an arc-shaped groove, and a rotating ring is slidably disposed inside the four arc-shaped grooves. The inner side of the rotating ring is provided with a first meshing tooth that meshes with the first gear, and the outer side of the rotating ring is provided with a third meshing tooth. The third meshing tooth is connected to a drive assembly disposed on one of the housings.

[0011] Furthermore, the rotating assembly includes a rotating rod disposed on the housing, the rotating rod having a thread and a second gear, a threaded sleeve being fitted on the thread, a support plate being disposed on one side of the threaded sleeve, the bottom of the support plate being connected to the top pressing plate, and the top of the rotating rod penetrating through the housing and being connected to the first gear.

[0012] Furthermore, a sliding groove is provided on one side of the housing.

[0013] Furthermore, the sliding assembly includes a fixed shaft disposed inside the slide groove, a slider sleeved on the fixed shaft, and the top of the slider being connected to the movable plate.

[0014] Furthermore, the drive assembly includes a connecting plate disposed on one of the housings, a motor disposed on the connecting plate, and a third gear meshing with the third meshing tooth mounted on the output end of the motor.

[0015] Furthermore, both the top clamping plate and the side clamping plate are provided with anti-slip surfaces.

[0016] The technical effects achieved by this utility model are as follows:

[0017] When the drive assembly is activated, its output power drives the rotating ring to perform circular motion within the arc-shaped groove. Because the first meshing tooth on the inner side of the rotating ring precisely meshes with the first gear, the rotation of the rotating ring causes the first gear to rotate synchronously. As the first gear rotates, it drives the rotating assembly to rotate, which in turn moves the top clamping plate downwards, thus clamping and fixing the stator for subsequent work. Simultaneously, the rotating assembly drives the second gear to rotate. When the second gear rotates, it drives the movable plate to move through the sliding assembly within the through hole via the second meshing tooth. The movement of the movable plate causes the side clamping plate to move closer to the side of the stator. Finally, the side clamping plate comes into close contact with the side of the stator and applies clamping force, thereby fixing and clamping the side of the stator. Through this series of coordinated mechanical transmissions, the side clamping plate and the top clamping plate can simultaneously and coordinately and effectively clamp and fix the side and top of the stator. This ensures that the stator can be firmly and evenly compressed during processing, greatly reducing processing errors and quality problems caused by uneven or insecure compression.

Detailed Implementation

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] like Figures 1-4 As shown, the technical solution adopted by this utility model is as follows: A stator clamping mechanism for motor stator processing includes a chassis 1, four housings 2 are provided on the top of the chassis 1, each housing 2 is provided with a rotating component and a through hole, and a first gear 3, a second gear 4 and a top clamping plate 5 are provided on the rotating component;

[0026] A sliding groove 6 is provided on the chassis 1. A sliding component is provided inside the sliding groove 6. A movable plate 7 that moves inside the through hole is provided on the sliding component. A second meshing tooth 8 that meshes with the second gear 4 is provided on one side of the movable plate 7. A side pressing plate 9 is provided on the movable plate 7.

[0027] Each of the four housings 2 has an arc-shaped groove 10. A rotating ring 11 is slidably arranged inside the four arc-shaped grooves 10. A first meshing tooth 12 that meshes with the first gear 3 is arranged on the inner side of the rotating ring 11. A third meshing tooth 13 is arranged on the outer side of the rotating ring 11. The third meshing tooth 13 is connected to a drive component arranged on one of the housings 2.

[0028] The rotating assembly includes a rotating rod 14 mounted on the housing 2. The rotating rod 14 is provided with a thread and a second gear 4. A threaded sleeve 15 is fitted on the thread. A support plate 16 is provided on one side of the threaded sleeve 15. The bottom of the support plate 16 is connected to the top pressing plate 5, and the top of the rotating rod 14 extends through the housing 2 and is connected to the first gear 3.

[0029] When the first gear 3 rotates, the first gear 3 drives the rotating rod 14 to rotate, and the rotating rod 14 drives the threaded sleeve 15 to move downward, thereby driving the support plate 16 and the top pressing plate 5 to move downward to press the stator.

[0030] Meanwhile, a sliding groove 17 is provided on one side of the housing 2. The sliding groove 17 allows the threaded sleeve 15 to move the top pressing plate 5 downwards, while also moving the side pressing plate 9.

[0031] The sliding assembly includes a fixed shaft 18 disposed inside the slide groove 6, a slider 19 sleeved on the fixed shaft 18, the top of the slider 19 being connected to the movable plate 7, and the slider 19 moving on the fixed shaft 18 inside the slide groove 6 when the movable plate 7 moves.

[0032] The drive assembly includes a connecting plate disposed on one of the housings 2, a motor 20 disposed on the connecting plate, and a third gear 21 that meshes with the third meshing tooth 13 is mounted on the output end of the motor 20. The motor 20 drives the third gear 21 to rotate, and the third meshing tooth 13 causes the rotating ring 11 to move inside the arc groove 10.

[0033] Both the top clamping plate 5 and the side clamping plate 9 are provided with anti-slip surfaces, which can increase friction and improve the fixing effect.

[0034] The working principle of this utility model is as follows: When the drive assembly is started, its output power drives the rotating ring 11 to make circular motion within the arc groove 10. Since the first meshing tooth 12 on the inner side of the rotating ring 11 precisely meshes with the first gear 3, the rotation of the rotating ring 11 will drive the first gear 3 to rotate synchronously. As the first gear 3 rotates, the first gear 3 drives the rotating assembly to rotate. The rotating assembly drives the top pressing plate 5 to move downward, thereby pressing and fixing the stator, which facilitates subsequent work. At the same time, the rotating assembly drives the second gear 4 to rotate. When the second gear 4 rotates, the second meshing tooth 8 drives the movable plate 7 to move inside the through hole through the sliding assembly. The movement of the movable plate 7 drives the side pressing plate 9 to move closer to the side of the stator. Finally, the side pressing plate 9 makes close contact with the side of the stator and applies a pressing force, thereby fixing and pressing the side of the stator. Through such a series of coordinated mechanical transmissions, the side pressing plate 9 and the top pressing plate 5 can simultaneously and coordinately press and fix the side and top of the stator effectively. This ensures that the stator can be firmly and evenly compressed during processing, greatly reducing processing errors and quality problems caused by uneven or insecure compression.

[0035] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
