Abstract
Description
Technical Field
[0001] This utility model relates to the field of motor stator and rotor core technology, specifically to a shaping device for processing motor stator and rotor cores. Background Technology
[0002] The stator and rotor cores are crucial components in electric motors and generators, primarily composed of thin iron sheets. In electric motors, the stator and rotor cores are placed inside the rotor, while in generators, they are placed inside the stator. The stator and rotor cores have a stacked structure; during manufacturing, they are typically made by laminating multiple thin iron sheets. These sheets are coated with insulating varnish to isolate them from each other and significantly reduce magnet losses.
[0003] In the processing of motor stator and rotor cores, the cores need to be flattened and shaped. Currently, when flattening and shaping the cores, a single clamping force from above is mostly used, and the actual flattening effect of the cores needs to be improved. Therefore, it is particularly important to improve the existing shaping device and design a new shaping device for motor stator and rotor core processing to solve the above-mentioned technical defects and improve the practicality of the overall shaping device. Utility Model Content

This device provides bidirectional flattening, which not only reduces processing steps and improves actual flattening efficiency, but also enhances the flattening effect of the core product. By using a damping spring in conjunction with a compression spring, the first pressure plate is buffered, increasing the buffer distance between the first pressure plate and the stator / rotor core. This prevents the first pressure plate from applying excessive pressure to the stator / rotor core upon initial contact, thus avoiding damage and affecting its use. This invention addresses the problems mentioned in the background section.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A shaping device for machining motor stator and rotor cores includes a worktable body, a first pressure plate on the top of the worktable body, a fitting component on the top of the first pressure plate, a second pressure plate slidably connected to the top of the worktable body and below the first pressure plate, a guide groove on the outer side of the second pressure plate and on the top of the worktable body, a guide frame fixedly connected to the end of the guide groove away from the second pressure plate, and a material unloading frame fixedly connected to the top of the worktable body and near the second pressure plate.
[0007] The bonding assembly is used for buffering between the first pressure plate and the iron core. The bonding assembly consists of a moving plate, a rotating block, multiple sets of telescopic rods, a sliding block, a fixed block, and a limiting ball. The moving plate is located above the first pressure plate. The rotating block is fixedly connected to the top of the first pressure plate. The multiple sets of telescopic rods are rotatably connected to the outside of the rotating block. The sliding block is rotatably connected to the end of the telescopic rod away from the rotating block and slidably connected to the bottom of the moving plate. The multiple sets of fixed blocks are respectively fixedly connected to the four sides of the bottom of the moving plate. The limiting ball is fixedly connected to the inside of the fixed block.
[0008] As a preferred embodiment of this utility model, limit plates are fixedly connected to all four sides of the bottom of the first pressure plate, and the top of the movable plate is fixedly connected to the drive end of the first telescopic cylinder, which is fixedly installed on the top of the workbench body.

[0015] In this invention, the design of the first pressure plate, the second pressure plate, and the bonding component allows the first and second pressure plates to be close to each other, enabling pressure to be applied to both ends of the stator and rotor cores.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to 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.
[0022] Example:
[0023] Please see Figures 1-4 This utility model provides a technical solution:
[0024] A shaping device for machining motor stator and rotor cores includes a workbench body 1, a first pressure plate 2 on the top of the workbench body 1, a bonding component 3 on the top of the first pressure plate 2, a second pressure plate 4 slidably connected to the top of the workbench body 1 and below the first pressure plate 2, a guide groove 5 on the outer side of the second pressure plate 4 and on the top of the workbench body 1, a guide frame 6 fixedly connected to the end of the guide groove 5 away from the second pressure plate 4, and a material unloading frame 7 fixedly connected to the top of the workbench body 1 and the end near the second pressure plate 4.
[0025] The bonding assembly 3 is used for buffering between the first pressure plate 2 and the iron core. The bonding assembly 3 consists of a moving plate 8, a rotating block 9, multiple sets of telescopic rods 10, a sliding block 11, a fixed block 12, and a limiting ball 13. The moving plate 8 is located above the first pressure plate 2. The rotating block 9 is fixedly connected to the top of the first pressure plate 2. The multiple sets of telescopic rods 10 are rotatably connected to the outside of the rotating block 9. The sliding block 11 is rotatably connected to the end of the telescopic rod 10 away from the rotating block 9 and slidably connected to the bottom of the moving plate 8. The multiple sets of fixed blocks 12 are respectively fixedly connected to the four sides of the bottom of the moving plate 8. The limiting ball 13 is fixedly connected to the inside of the fixed block 12.
[0026] Furthermore, limit plates 14 are fixedly connected to the bottom of the first pressure plate 2 around its perimeter, and the top of the moving plate 8 is fixedly connected to the drive end of the first telescopic cylinder. The first telescopic cylinder is fixedly installed on the top of the workbench body 1. Activating the first telescopic cylinder drives the moving plate 8 to move, causing the first pressure plate 2 to move. Activating the second telescopic cylinder drives the second pressure plate 4 to move. When the stator and rotor cores move to the top of the second pressure plate 4, the first pressure plate 2 and the second pressure plate 4 move closer to each other, allowing pressure to be applied to both ends of the stator and rotor cores. When pressure is applied to the stator and rotor cores, the limit plates 14 can prevent the stator and rotor cores from shifting, thus affecting the shaping of the stator and rotor cores. Bidirectional flattening not only reduces processing steps and improves actual flattening efficiency, but also improves the flattening effect of the core products.
[0027] The bottom of the second pressure plate 4 is fixedly connected to the drive end of the second telescopic cylinder, which is fixedly installed inside the workbench body 1. The end of the guide groove 5 away from the second pressure plate 4 is fixedly installed with a third telescopic cylinder, and the drive end of the third telescopic cylinder is fixedly connected to a guide block 15. The top of the workbench body 1 and the rear end of the second pressure plate 4 is slidably connected to a push block 16. The push block 16 extends into the interior of the workbench body 1 and is fixedly connected to a fourth telescopic cylinder, the drive end of which is fixedly installed inside the workbench body 1. When the stator and rotor cores are moved to the interior of the guide groove 5 through the guide frame 6, the third telescopic cylinder is activated to drive the guide block 15 to move, so that the guide block 15 can guide the stator and rotor cores and move them to the top of the second pressure plate 4. When the stator and rotor cores are shaped, the third telescopic cylinder is activated to drive the push block 16 to move, so that the stator and rotor cores are moved to the interior of the unloading rack 7 for unloading. The entire operation is automated, increasing the efficiency of stator and rotor core shaping.
[0028] Secondly, a damping spring 17 is fixedly connected to the outside of the sliding block 11 and inside the moving plate 8. The damping spring 17 is fixedly connected to the moving plate 8. A compression spring 18 is sleeved on one end of the telescopic rod 10 near the sliding block 11. The two ends of the compression spring 18 are fixedly connected to the telescopic rod 10 and the sliding block 11, respectively. When the first pressure plate 2 contacts the stator and rotor core, the first pressure plate 2 is subjected to a relative force that drives the rotating block 9 to move, so that multiple sets of telescopic rods 10 drive the sliding block 11 to move and squeeze the damping spring 17. At the same time, when the sliding block 11 moves to the outside of the fixed block 12 and cannot move, the telescopic rod 10 squeezes the compression spring 18. The damping spring 17 and the compression spring 18 can buffer the first pressure plate 2, increase the buffer distance between the first pressure plate 2 and the stator and rotor core, and prevent the first pressure plate 2 from applying too much pressure to the stator and rotor core at the first moment when it contacts the stator and rotor core, which would damage the stator and rotor core and affect its use.
[0029] Furthermore, a limiting rod 19 is fixedly connected to one end of the sliding block 11 near the limiting ball 13. A limiting groove 20 is formed inside the limiting ball 13. The limiting rod 19 is limited to the limiting ball 13 through the limiting groove 20. When the sliding block 11 moves, it drives the limiting rod 19 to move, so that the limiting rod 19 moves into the limiting groove 20 and is limited to the limiting ball 13. When the first pressure plate 2 is reset, the limiting ball 13 limits the sliding block 11 to prevent the first pressure plate 2 from sliding during reset and colliding with the stator and rotor cores, causing the stator and rotor cores to deviate.
[0030] Furthermore, sliding rods 21 are fixedly connected to all four sides of the top of the first pressure plate 2. The sliding rods 21 are slidably connected to the moving plate 8. When the first pressure plate 2 is displaced, the sliding connection between the sliding rods 21 and the moving plate 8 enables the first pressure plate 2 to be moved, thus preventing the first pressure plate 2 from shifting.
[0031] In this embodiment, the specific implementation scenario is as follows: When the stator and rotor cores are moved to the inside of the guide groove 5 via the guide frame 6, the third telescopic cylinder is activated to drive the guide block 15 to move, so that the guide block 15 can guide the stator and rotor cores and move the stator and rotor cores to the top of the second pressure plate 4. The first telescopic cylinder is activated to drive the moving plate 8 to move, so that the first pressure plate 2 moves. The second telescopic cylinder is activated to drive the second pressure plate 4 to move. When the stator and rotor cores are moved to the top of the second pressure plate 4, the first pressure plate 2 and the second pressure plate 4 move closer to each other, so that pressure can be applied to both ends of the stator and rotor cores. When pressure is applied to the stator and rotor cores, the limiting plate 14 can prevent the stator and rotor cores from shifting, which would affect the shaping of the stator and rotor cores. Bidirectional flattening not only reduces the processing steps and improves the actual flattening efficiency, but also improves the flattening effect of the core products. When the first pressure plate 2 contacts the stator and rotor cores, the first pressure plate 2 is subjected to a relative force that drives the rotating block 9 to move, so that the multiple sets of telescopic rods 10 drive the sliding block 11 to move and compress the damping spring. 17. Simultaneously, when the sliding block 11 is displaced to the outside of the fixed block 12 and cannot move further, the telescopic rod 10 presses the compression spring 18. The damping spring 17, in conjunction with the compression spring 18, buffers the first pressure plate 2, increasing the buffer distance between the first pressure plate 2 and the stator / rotor core. This prevents the first pressure plate 2 from applying excessive pressure to the stator / rotor core upon initial contact, which could damage the core and affect its use. When the stator / rotor core is shaped, the first pressure plate 2 is reset. When in position, the sliding block 11 is limited by the limiting ball 13 to prevent the first pressure plate 2 from sliding during reset and colliding with the stator and rotor core, causing the stator and rotor core to deviate. When the stator and rotor core is shaped, the third telescopic cylinder is activated to drive the push block 16 to move, so that the stator and rotor core is moved into the inside of the unloading rack 7 for unloading. The whole operation is automated, increasing the efficiency of stator and rotor core shaping. Compared with the existing shaping device, this utility model can improve the overall practicality of the shaping device through design.
[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
