Abstract
Description
Technical Field
[0001] This utility model belongs to the field of motor stator polishing technology, and particularly relates to a limiting mechanism for motor stator polishing. Background Technology
[0002] The motor stator is the stationary core component of the motor, mainly composed of the stator core, stator windings, and housing, and is a key component for realizing electromechanical energy conversion.
[0003] The problem with the above technology is that the existing motor stator polishing process lacks a limiting mechanism, which cannot limit the movement according to the width, thickness and inner ring of different stators. During polishing, it is easy to cause defects such as stator displacement, vibration or eccentricity, which leads to wear of the polishing wheel, unstable equipment operation, and reduced production efficiency and yield. Utility Model Content
[0004] In view of the problems existing in the prior art, this utility model provides a limiting mechanism for polishing motor stator that can overcome or at least partially solve the above problems.
[0005] This utility model is implemented as follows: a limiting mechanism for polishing motor stator includes a mounting base, a pressing block, mounting feet, a protective frame, and a drive motor. The top of the protective frame is fixedly connected to the surface of the mounting base, the left side surface of the mounting feet is fixedly connected to the right side surface of the pressing block, the surface of the drive motor is fixedly connected to the inner wall of the protective frame, a limiting mechanism is provided on the mounting base, and an auxiliary mechanism is provided under the mounting base.
[0006] The limiting mechanism is used to limit the position of the motor stator;
[0007] The auxiliary mechanism is used to fix the motor stator.
[0008] To improve the efficiency of the limiting mechanism, preferably, the limiting mechanism includes a main gear, a rack, a slide rod, a wedge block, a clamping plate, and a horizontal plate. The surface of the main gear is meshed with the surface of the rack, the bottom of the slide rod is fixedly connected to the top of the rack, the surface of the wedge block is fixedly connected to the surface of the clamping plate, the top of the slide rod is slidably connected to the bottom of the wedge block, and the bottom of the horizontal plate is fixedly connected to the top of the mounting base. Through the meshing transmission between the main gear and the rack, the slide rod is driven to move, pushing the wedge block to slide along the clamping plate, thereby achieving rapid clamping and limiting of the motor stator. This enables limiting of motor stators of different widths, effectively avoiding displacement and vibration during polishing, and significantly improving the limiting accuracy and polishing quality.
[0009] To improve the polishing effect, preferably, the auxiliary mechanism includes a worm, a worm wheel, a driven gear, a toothed plate, a lead screw, a slider, and a turntable. The output end of the drive motor is fixedly connected to the front end of the worm via a rotating shaft. The surface of the worm is fixedly connected to the surface of the worm wheel. The rear end of the worm is fixedly connected to the left side surface of the driven gear via a rotating shaft. The surface of the driven gear meshes with the surface of the toothed plate. The surface of the turntable is connected to the surface of the rotating shaft via a transmission component. The drive motor drives the worm to rotate, and through multi-stage transmission via the worm wheel and driven gear, the toothed plate drives the pressure block to rise and fall to adjust the height of the polishing equipment, adapting to stators of different thicknesses. This ensures that the polishing wheel maintains optimal contact pressure with the stator surface, avoiding over-polishing or under-polishing, improving polishing efficiency and accuracy, and reducing equipment debugging time and labor costs.
[0010] To improve operational stability, preferably, a telescopic rod is provided on the surface of the horizontal plate, and a first spring is provided on the surface of the telescopic rod. The two ends of the first spring are fixedly connected to the surface of the telescopic rod. After polishing, the first spring pushes the telescopic rod to reset by its own elastic force, causing the clamping plate to loosen, which facilitates the quick disassembly of the stator and ensures the flexibility and stability of the limit mechanism operation.
[0011] To improve the practicality of the mechanism, preferably, a second spring is provided at the front end of the rack. The front end of the second spring is fixedly connected to the left side of the inner wall of the mounting base, and the rear end of the second spring is fixedly connected to the front end of the rack. The top of the worm gear is fixedly connected to the bottom of the main gear through a rotating shaft. When the drive motor stops working, the rack can be automatically returned to its original position by relying on the elastic restoring force of the second spring, so that the clamping mechanism returns to its initial state. This facilitates the replacement of motor stators of different specifications and improves the operational convenience and durability of the limiting mechanism.
[0012] To improve the reliability of the limit, preferably, a cylinder is provided at the top of the slider, and a fixing pin is provided at the output end of the cylinder. The output end of the cylinder is fixedly connected to the bottom of the fixing pin, the bottom of the cylinder is fixedly connected to the bottom of the slider, and the front end of the toothed plate is fixedly connected to the surface of the mounting foot. By driving the fixing pin to insert into the inner ring of the motor stator through the cylinder on the slider, precise axial and radial positioning can be achieved during polishing. The extension and retraction of the cylinder controls the quick insertion and removal of the fixing pin, which can adapt to stators with different inner ring specifications, thereby improving polishing accuracy and yield.
[0013] To improve the integrity of the mechanism, preferably, the rear end of the telescopic rod is fixedly connected to the surface of the horizontal plate, and the output end of the telescopic rod is fixedly connected to the surface of the clamping plate. The telescopic rod provides guidance for the clamping plate to ensure accurate displacement. In conjunction with the first spring, when the telescopic rod moves, the first spring can buffer the impact force and assist in the reset. The two work together to ensure a smooth and efficient limiting process and avoid damage to the stator due to rigid collision.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] This utility model incorporates a limiting mechanism, an auxiliary mechanism, a main gear, a rack, a slide bar, a wedge block, a clamping plate, a horizontal plate, a worm gear, a worm wheel, a driven gear, a toothed plate, a lead screw, a slider, and a turntable. The limiting mechanism is used to limit the movement of the motor stator, and the auxiliary mechanism is used to fix the motor stator. Through the meshing transmission of the main gear and the rack, the slide bar is moved, pushing the wedge block to slide along the clamping plate, achieving rapid clamping and limiting of the motor stator. This allows for limiting of motor stators of different widths, effectively avoiding displacement and vibration during polishing, significantly improving the limiting accuracy and polishing quality. The system is powered by a driving motor. The worm gear drives the worm wheel to rotate, and through the worm wheel and driven gear, the toothed plate drives the pressure block to rise and fall to adjust the height of the polishing equipment. This adapts to stators of different thicknesses, ensuring that the polishing wheel and the stator surface maintain the optimal contact pressure, avoiding over-polishing or under-polishing, improving polishing efficiency and precision, reducing equipment debugging time and labor costs. It solves the problem that existing motor stator polishing processes lack a limiting mechanism, making it impossible to limit the movement according to different stator widths, thicknesses, and inner rings. This can easily lead to stator displacement, vibration, or eccentricity defects during polishing, causing polishing wheel wear, unstable equipment operation, and reduced production efficiency and yield.

[0022] The structure of this utility model will now be described in detail with reference to the accompanying drawings.
[0023] like Figures 1 to 4As shown in the figure, the present invention provides a limiting mechanism for polishing motor stator, including a mounting base 1, a pressing block 2, mounting feet 3, a protective frame 4, and a drive motor 5. The top of the protective frame 4 is fixedly connected to the surface of the mounting base 1, the left side surface of the mounting feet 3 is fixedly connected to the right side surface of the pressing block 2, and the surface of the drive motor 5 is fixedly connected to the inner wall of the protective frame 4. A limiting mechanism 6 is provided on the mounting base 1, and an auxiliary mechanism 7 is provided below the mounting base 1. The limiting mechanism 6 is used to limit the motor stator, and the auxiliary mechanism 7 is used to fix the motor stator. The limiting mechanism 6 includes a main gear 601, a rack 602, a slide rod 603, a wedge block 604, a clamping plate 605, and a horizontal plate 606. The surface of the main gear 601 meshes with the surface of the rack 602, and the slide rod 603... The bottom is fixedly connected to the top of the rack 602, the surface of the inclined block 604 is fixedly connected to the surface of the clamping plate 605, the top of the slide rod 603 is slidably connected to the bottom of the inclined block 604, and the bottom of the horizontal plate 606 is fixedly connected to the top of the mounting base 1. Through the meshing transmission of the main gear 601 and the rack 602, the slide rod 603 is driven to move, pushing the inclined block 604 to slide along the clamping plate 605, realizing the rapid clamping and limiting of the motor stator, realizing the limiting of motor stators of different widths, effectively avoiding displacement and vibration during polishing, and significantly improving the limiting accuracy and polishing quality. The auxiliary mechanism 7 includes a worm gear 701, a worm wheel 702, a driven gear 703, a toothed plate 704, a lead screw 705, a slider 706, and a turntable 707. The output end of the drive motor 5 is fixedly connected to the worm gear 701 through a rotating shaft. The front end of the worm gear 701 is fixedly connected to the surface of the worm wheel 702. The rear end of the worm gear 701 is fixedly connected to the left side surface of the driven gear 703 via a rotating shaft. The surface of the driven gear 703 is meshed with the surface of the toothed plate 704. The surface of the turntable 707 is connected to the surface of the rotating shaft via a transmission component. The worm gear 701 is driven to rotate by the drive motor 5. Through multi-stage transmission via the worm wheel 702 and the driven gear 703, the toothed plate 704 drives the pressure block 2 to rise and fall to adjust the height of the polishing equipment, adapting to stators of different thicknesses. This ensures that the polishing wheel and the stator surface maintain the best contact pressure, avoiding over-polishing or under-polishing, improving polishing efficiency and accuracy, and reducing equipment debugging time and labor costs. A telescopic rod 8 is provided on the surface of the horizontal plate 606, and a first spring 9 is provided on the surface of the telescopic rod 8. Spring 9 is fixedly connected to the surface of telescopic rod 8 at both ends. After polishing, spring 9 pushes telescopic rod 8 back to its original position using its own elastic force, causing clamping plate 605 to loosen, facilitating quick disassembly of the stator and ensuring the flexibility and stability of the limit mechanism operation. A second spring 10 is provided at the front end of rack 602. The front end of the second spring 10 is fixedly connected to the left side of the inner wall of mounting base 1, and the rear end of the second spring 10 is fixedly connected to the front end of rack 602. The top of worm gear 702 is fixedly connected to the bottom of main gear 601 through a rotating shaft. When drive motor 5 stops working, the elastic restoring force of second spring 10 can drive rack 602 to automatically return to its original position, restoring the clamping mechanism to its initial state. This facilitates the replacement of motor stators of different specifications and improves the operational convenience and durability of the limit mechanism.A cylinder 11 is mounted on the top of the slider 706, and a fixing pin 12 is mounted on the output end of the cylinder 11. The output end of the cylinder 11 is fixedly connected to the bottom of the fixing pin 12, and the bottom of the cylinder 11 is fixedly connected to the bottom of the slider 706. The front end of the toothed plate 704 is fixedly connected to the surface of the mounting foot 3. The cylinder 11 on the slider 706 drives the fixing pin 12 to insert into the inner ring of the motor stator, which can achieve precise axial and radial positioning during polishing. The extension and retraction of the cylinder 11 controls the quick insertion and removal of the fixing pin 12, adapting to stators with different inner ring specifications, improving polishing accuracy and yield. The rear end of the telescopic rod 8 is fixedly connected to the surface of the horizontal plate 606, and the output end of the telescopic rod 8 is fixedly connected to the surface of the clamping plate 605. The telescopic rod 8 provides guidance for the clamping plate 605 to ensure accurate displacement. In conjunction with the first spring 9, when the telescopic rod 8 moves, the first spring 9 can buffer the impact force and assist in reset. The two work together to ensure a smooth and efficient limiting process, avoiding damage to the stator due to rigid collisions.
[0024] The working principle of this utility model:
[0025] When polishing the motor stator is required, first place the motor stator in the middle of the mounting base 1, then start the drive motor 5. The output end of the drive motor 5 drives one end of the worm gear 701 to rotate via the rotating shaft. The rotation of the worm gear 701 causes the other end to drive the driven gear 703 to rotate. The driven gear 703 meshes with the toothed plate 704, causing the pressure block 2 to rise and fall to adjust the height of the polishing equipment, adapting to stators of different thicknesses, ensuring that the polishing wheel maintains the optimal contact pressure with the stator surface, avoiding over-polishing or under-polishing. Meanwhile, the turntable 707 rotates synchronously with the rotating shaft via a transmission component. 7. Rotation causes the lead screw 705 to rotate. Since the slider 706 is connected to the lead screw 705 via a thread, the slider 706, along with its cylinder 11 and fixing pin 12, all move along the lead screw 705. When the slider 706 is moved to the exact center of the bottom of the motor stator, the cylinder 11 inserts the fixing pin 12 into the inner ring of the motor stator, thus achieving precise axial and radial positioning during polishing. The extension and retraction of the cylinder 11 controls the rapid insertion and removal of the fixing pin 12, adapting to stators with different inner ring specifications, improving polishing accuracy and yield. Simultaneously, the worm gear 702 meshes with the worm 701. The worm gear 702 rotates synchronously, and through the rotating shaft, it causes the main gear 601 to rotate. Since the two racks 602 in the mounting base 1 mesh with the two sides of the main gear 601 respectively, the racks 602 move in opposite directions, thereby driving the slide bar 603 to move and pushing the inclined block 604 to slide along the clamping plate 605, realizing the rapid clamping and limiting of the motor stator. This achieves the limiting of motor stators of different widths, effectively avoiding displacement and vibration during polishing, and significantly improving the limiting accuracy and polishing quality. The telescopic rod 8 set on one side of the horizontal plate 606 further provides guidance for the clamping plate 605. To ensure precise displacement, the first spring 9, which is fitted on the surface of the telescopic rod 8, pushes the telescopic rod 8 back to its original position using its own elastic force, causing the clamping plate 605 to loosen, facilitating quick disassembly of the stator and ensuring the flexibility and stability of the limit mechanism operation. When the drive motor 5 stops working, the elastic restoring force of the second spring 10 can drive the rack 602 to automatically return to its original position, restoring the clamping mechanism to its initial state. This facilitates the replacement of motor stators of different specifications, thereby improving the operational convenience and durability of the limit mechanism, and further enhancing the practicality and reliability of the entire mechanism.
