Description

Technical Field

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

[0002] The main function of an electric motor is to generate torsional torque, thereby converting electrical energy into mechanical energy. The stator is an important component of the motor, and its main component is the coil. The stator is the stationary part of the motor, and it needs to be clamped and positioned during the manufacturing process.

[0003] Currently, when clamping motor stators during machining, the stator is usually clamped and fixed directly by grippers. However, ordinary clamping grippers are prone to loosening and causing the stator to fall off when operated manually. It is inconvenient to automatically adjust and adapt to different stator sizes to clamp them, it is inconvenient to equip the stator with a retaining and anti-collision structure, and it is inconvenient to automatically move and accurately position the stator according to the machining requirements. Therefore, there is an urgent need for a stator clamping mechanism for motor stator machining to solve the above problems. Utility Model Content

[0004] The technical problem this utility model aims to solve is that it is currently inconvenient to equip the stator with an automatic adjustment and adaptation mechanism to prevent slipping and clamping the stator according to the stator size during the current motor stator processing, and it is also inconvenient to perform precise positioning processing for the automated displacement of the stator.

[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: a stator clamping mechanism for motor stator processing, including a fixed frame and a stator clamping mechanism fixedly disposed on the fixed frame and disposed opposite to it, and further including a positioning mechanism, the positioning mechanism being disposed on the stator clamping mechanism, the bottom of the positioning mechanism being fixedly provided with a support platform, and further including an anti-collision mechanism, the anti-collision mechanism being fixedly disposed at the bottom of the support platform.

[0006] To facilitate the fitting and clamping of stators of different sizes, the stator clamping mechanism includes a telescopic cylinder fixedly connected to one side wall of the fixed frame. The telescopic cylinder is connected to a transmission rack at its telescopic end. Both ends of the transmission rack are meshed with driven gears that are rotatably connected to the fixed frame. A rotating plate is fixedly connected to one end of the driven gear. A limiting rotating plate is rotatably connected between the top and bottom walls of one end of the fixed frame. The other end of the limiting rotating plate is rotatably connected to a connecting rotating plate that is rotatably connected to the other end of the rotating plate.

[0007] In order to facilitate the adjustment of the rotation angle of the stator after clamping, a support base is fixedly connected to the side wall of the connecting plate, a rotary motor is fixedly installed inside the support base, and a pressure plate is connected to the output end of the rotary motor. Another set of pressure plates is rotatably installed on the side wall of another set of the support base.

[0008] To facilitate the automatic and precise positioning of the compressed stator, the positioning mechanism includes a block with a nut fixedly connected to the bottom of the fixed frame. A threaded rod is threadedly connected to one set of the block with the nut. The two ends of the threaded rod are rotatably connected to a fixed box fixedly connected to the top of the support platform. A drive motor for driving the threaded rod to rotate is fixedly installed on one side wall of the fixed box. A guide rod is slidably connected to the other set of the block with the nut, and the two ends of the guide rod are fixedly connected to another set of the fixed boxes fixedly connected to the top of the support platform.

[0009] In order to facilitate the connection of the compressed stator and prevent collisions, the anti-collision mechanism includes a base plate fixedly connected to the bottom of the support platform, a flexible pad fixedly attached to the top of the base plate, and a baffle located below the stator compression mechanism fixedly connected to the edge of the base plate.

[0010] Furthermore, both sets of fixing boxes are fixedly equipped with scale plates, the side walls of both sets of fixing boxes are provided with opposite openings, and the pressing plates of both sets are fixedly affixed with anti-slip layers.

[0011] Preferably, the driven gear is arranged in a sector shape, the support base is arranged in a square shape, and the inner wall of the pressure plate is arranged in a V shape.

[0012] The beneficial effects of this utility model by adopting the above structure are as follows:

[0013] 1. By opening the telescopic cylinder to retract it, two sets of driven gears can be driven to rotate relative to each other along the transmission rack, thereby driving two sets of clamping plates to move relative to each other and clamp stators of different sizes.

[0014] 2. By turning on the drive motor, the threaded rod can be rotated, thereby automatically shifting the stator clamping mechanism to accurately position the clamped stator for subsequent processing;

[0015] 3. By setting flexible pads and baffles, the motor stator can be held in place and surrounded to prevent it from falling and causing damage. Attached Figure Description

Together with the embodiments of the present invention, they are used to explain the present invention and do not constitute a limitation to the present invention. Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1 As shown, in order to achieve the above functions, the technical solution adopted by this utility model is as follows: A stator clamping mechanism 2 for motor stator processing includes a fixed frame 1 and a stator clamping mechanism 2 fixedly disposed on the fixed frame 1 and disposed opposite to it. It also includes a positioning mechanism 3, which is disposed on the stator clamping mechanism 2 and can accurately position the stator on the stator clamping mechanism 2. A support platform 4 is fixedly disposed at the bottom of the positioning mechanism 3. It also includes an anti-collision mechanism 5, which is fixedly disposed at the bottom of the support platform 4 and can prevent the stator after being clamped by the stator clamping mechanism 2 from being collided.

[0024] like Figure 2 , 4As shown, the stator clamping mechanism 2 includes a telescopic cylinder 6 that is fixedly connected to one side wall of the fixed frame 1. The telescopic end of the telescopic cylinder 6 is connected to a transmission rack 7. Both ends of the transmission rack 7 are meshed with driven gears 8 arranged in a fan shape and rotatably connected to the fixed frame 1. A rotating plate 9 is fixedly connected to one end of the driven gear 8. A limiting rotating plate 10 is rotatably connected between the top wall and the bottom wall at one end of the fixed frame 1. The other end of the limiting rotating plate 10 is rotatably connected to a connecting rotating plate 1 that is rotatably connected to the other end of the rotating plate 9. 1. A square-shaped support base 12 is fixedly connected to the side wall of the connecting plate 11. A rotary motor 13 is fixedly installed inside the support base 12. The output end of the rotary motor 13 is connected to a pressure plate 14 with a V-shaped inner wall. Another set of pressure plates 14 is rotatably installed on the side wall of another set of support bases 12. Anti-slip layers are fixedly attached to both sets of pressure plates 14. The driven gear 8 meshes with the transmission rack 7 to press and fix the stator with the pressure plate 14. The rotary motor 13 can drive the stator pressed on the pressure plate 14 to automatically adjust the angle.

[0025] like Figure 3 As shown, the positioning mechanism 3 includes a nut-bearing block 15 fixedly connected to the bottom of the fixed frame 1. A threaded rod 16 is threadedly connected to one set of nut-bearing blocks 15. Fixed boxes 17 fixedly connected to the top of the support platform 4 are rotatably connected to both ends of the threaded rod 16. A scale plate is fixedly provided on both sets of fixed boxes 17 to facilitate viewing the movement position of the stator pressed by the stator pressing mechanism 2. Openings are provided on the side walls of the two sets of fixed boxes 17. A drive motor 18 for driving the threaded rod 16 to rotate is fixedly provided on one side wall of the fixed box 17. A guide rod 19 is slidably connected to the other set of nut-bearing blocks 15. Another set of fixed boxes 17 fixedly connected to the top of the support platform 4 is fixedly connected to both ends of the guide rod 19. The guide rod 19 can limit the direction of linear translation of the nut-bearing blocks 15.

[0026] like Figure 4 As shown, the anti-collision mechanism 5 includes a base plate 20 fixedly connected to the bottom of the support platform 4, a flexible pad 21 fixedly attached to the top of the base plate 20 to absorb and dampen the stator if it is accidentally dropped, and a baffle 22 located below the stator clamping mechanism 2 fixedly connected to the edge of the base plate 20, which can protect the stator from collision if it is accidentally dropped.

[0027] In practical use, the user holds the stator to be clamped between the two sets of clamping plates 14. If the stator accidentally falls, the bottom plate 20 can catch it. The flexible pad 21 can cushion the stator from shock and impact, and the baffles 22 around the stator can also protect it. Then, the telescopic cylinder 6 is opened to retract and drive the transmission rack 7 to move. The driven gears 8 at both ends mesh along the transmission rack 7 and rotate relative to each other. The two sets of rotating plates 9 rotate relative to each other, causing the two ends of the limiting rotating plate 10 to rotate along the fixed frame 1 and the connecting rotating plate 11, thereby connecting the rotating plates. Plate 11 can drive two sets of clamping plates 14 to move relative to each other to clamp and fix the stator. Turning on the rotary motor 13 drives the clamping plate 14 and the clamped stator to rotate and adjust the processing angle. Turning on the drive motor 18 drives the threaded rod 16 to rotate, and the nut block 15 moves along the guide rod 19, which drives the top stator clamping mechanism 2 and the clamped stator to move automatically. The distance the stator moves can be viewed in real time through the scale plate for precise positioning to meet different processing needs. The above is the whole process of using the stator clamping mechanism 2 for motor stator processing.
