Abstract
Description
Technical Field
[0001] This utility model relates to the field of motor rotor technology, and in particular to a motor rotor lamination stacking device. Background Technology
[0002] The motor is the core driving device of an electric tricycle. The rotor, as an important component of the motor, is mainly composed of components such as the rotor core, rotor windings, and shaft. In the production process, the manufacturing of the rotor core is particularly critical. It usually needs to be completed through a lamination process to ensure the dimensional accuracy and shape consistency of the rotor core, and also to effectively reduce eddy current losses and improve the efficiency and performance of the motor.
[0003] Application No. 202220659999.0 discloses a large motor stator and rotor lamination stacking device, comprising a base plate, with columns fixedly connected to the four corners of the top of the base plate; a top plate fixedly connected to the top of the columns; a cylinder mounted on the top of the top plate; a pressure plate fixedly connected to the retracted end of the cylinder; cross-shaped sliding grooves on the four sides of the center of the top of the base plate; a worm gear rotatably connected inside the inner cavity; a shaft at the bottom of the worm gear; a worm wheel fixedly connected through the middle of the shaft; and first and second external threads with opposite thread directions at both ends of the worm gear and the shaft. Both the first and second external threads are threadedly connected to threaded sleeves; and adjusting rods are fixedly connected to the top of each threaded sleeve. By adjusting the diameter of the four adjusting rod components, stator and rotor laminations of different diameters can be fixed, improving the practicality of the device and facilitating its widespread use.
[0004] The above solution has shortcomings in use. Due to the different thicknesses of rotor laminations of different motors, the height difference of multiple rotor laminations after stacking will be large. However, the length of the adjusting rod is fixed. When stacking rotor laminations with larger thickness, the adjusting rod may not be able to fix all the rotor laminations, which will affect the stacking work. Therefore, we provide a motor rotor lamination stacking device. Utility Model Content

[0029] 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.
[0030] First Embodiment
[0031] As attached Figure 1 Appendix Figure 2 Appendix Figure 3 With appendix Figure 4 As shown: A motor rotor lamination stacking device includes a carrier plate 1 and an adjustment groove 2 arranged in a ring on the upper surface of the carrier plate 1. The bottom surface of the carrier plate 1 is fixedly connected to a ring of support legs 6. The bottom ends of a group of support legs 6 are fixedly connected to a base 7. By utilizing the cooperation between the support legs 6 and the base 7, a stable support can be formed for the carrier plate 1, which can prevent the carrier plate 1 from sliding during the stacking of rotor laminations.
[0032] The fixing component 3 is located below the carrier plate 1 and includes an adjusting rod 301 disposed inside each adjusting groove 2. The adjusting rod 301 is adapted to the adjusting groove 2 and can slide inside the adjusting groove 2, thereby being suitable for rotor laminations of different sizes.
[0033] A retraction mechanism for changing the height of the adjusting rod 301 is provided below the carrier plate 1. The retraction mechanism of the fixing assembly 3 includes retraction cylinders 302 arranged in a ring below the carrier plate 1. Each retraction cylinder 302 is sleeved on the outside of the bottom end of the adjusting rod 301. A spring 303 is fixedly connected to the inner bottom wall of each retraction cylinder 302. The top end of each spring 303 is connected to the bottom end of the adjusting rod 301. The spring 303 can push the adjusting rod 301 by its extension, so that the adjusting rod 301 can extend a sufficient length above the carrier plate 1, thus making it suitable for stacking rotor laminations of different thicknesses. When stacking, if the adjusting rod 301 is higher than the rotor lamination, as the stacking work is carried out, the adjusting rod 301 will gradually penetrate into the retraction cylinder 302, thus making it suitable for rotor laminations of different thicknesses.
[0034] Each adjusting rod 301 has a limiting groove 304 on its outer surface, and a stop rod 305 is slidably connected to the inner wall of each limiting groove 304. The top of each stop rod 305 is connected to the bottom surface of the carrier plate 1. By using the cooperation between the limiting groove 304 and the stop rod 305, the movement of the adjusting rod 301 can be limited, thereby preventing the adjusting rod 301 from separating from the shrink cylinder 302.
[0035] The fixing assembly 3 also includes a support plate 306 disposed below the carrier plate 1. The upper surface of the support plate 306 is fixedly connected with a ring of hanging rods 307. The top end of each hanging rod 307 is connected to the bottom surface of the carrier plate 1. The upper surface of the support plate 306 is provided with a ring of support grooves 308. The inner wall of each support groove 308 is slidably connected with a support column 309. The top end of each support column 309 is connected to the bottom end of the shrink cylinder 302. The support plate 306 can be suspended by the hanging rods 307, and the support column 309 will support the shrink cylinder 302, thereby ensuring the stability when the adjusting rod 301 compresses the spring 303, and ensuring that the spring 303 can push the adjusting rod 301 to reset after extension.
[0036] The upper surface of the support plate 306 is fixedly connected with a ring of vertical plates 310. Each vertical plate 310 is slidably connected with a set of guide columns 311. One end of each set of guide columns 311 is connected to the outer surface of each shrink cylinder 302. By using the cooperation between the vertical plates 310 and the guide columns 311, the shrink cylinder 302 can be stabilized and the shrink cylinder 302 can be prevented from deflecting.
[0037] Second Embodiment
[0038] As attached Figure 1 Appendix Figure 2 With appendix Figure 5 As shown: The pushing component 4 is located below the carrier plate 1 and is used to drive the adjusting rod 301 to move synchronously. The pushing component 4 includes an electric push rod 401 installed on the bottom surface of the carrier plate 1. A circular plate 402 is installed on the telescopic end of the electric push rod 401. A ring of connecting plates 403 are hinged to the outer surface of the circular plate 402. The bottom end of each connecting plate 403 is hinged to the outer surface of the shrinking cylinder 302. When the electric push rod 401 extends, the circular plate 402 pushes the connecting plate 403, and the connecting plate 403 pushes the shrinking cylinder 302. At the same time, the adjusting rod 301 also moves synchronously and presses against the inner ring surface of the rotor lamination, thus stabilizing the rotor lamination. This method is applicable to rotor laminations of different sizes.
[0039] The outer surface of the circular plate 402 is provided with annularly arranged stabilizing grooves 404. Each stabilizing groove 404 has a slidably connected stabilizing plate 405 on its inner wall. The top of each stabilizing plate 405 is connected to the bottom surface of the carrier plate 1. By using the cooperation between the stabilizing plate 405 and the stabilizing groove 404, the circular plate 402 can be stabilized to prevent the circular plate 402 from shifting its position and the risk of the connecting plate 403 breaking.
[0040] A set of stabilizing plates 405 are fixedly connected to the outer surface of the plate by a fastening ring 406, and the fastening ring 406 is located at the bottom of the stabilizing plate 405. The fastening ring 406 can be used to reinforce the stabilizing plates 405, thereby ensuring the stability of the stabilizing plates 405 in guiding the circular plate 402.
[0041] Third Embodiment
[0042] As attached Figure 1 As shown: The pressing assembly 5 is set above the carrier plate 1 and is used to stack the rotor laminations. The pressing assembly 5 consists of a mounting plate, a cylinder and a pressure plate. The mounting plate can fix the cylinder. When the cylinder works, it will push the pressure plate down, and the pressure plate will complete the stacking of the rotor laminations.
[0043] Working principle: During use, the rotor laminations are placed on the carrier plate 1 and wrapped around the adjusting rod 301. Then, the electric push rod 401 is extended, which pushes the circular plate 402 downward. The circular plate 402 pushes the connecting plate 403, which in turn pushes the shrinking cylinder 302. At the same time, the adjusting rod 301 moves synchronously and presses against the inner ring surface of the rotor laminations, thus stabilizing the rotor laminations. Finally, the pressing assembly 5 is controlled to work. The pressure plate in the pressing assembly 5 first contacts the adjusting rod 301. As the pressing assembly 5 descends, the adjusting rod 301 gradually retracts into the shrinking cylinder 302, ensuring that the adjusting rod 301 is always in a fixed state for the rotor laminations, which is beneficial for the stacking of the rotor laminations.
