Description

Technical Field

[0001] This utility model relates to the field of stator coil processing technology, specifically a stator coil winding shaping machine. Background Technology

[0002] With the rapid development of numerous fields such as industrial automation, electric vehicles, aerospace, and home appliances, electric motors, as key power drive devices, have been widely used. The performance and quality of electric motors directly affect the operating efficiency and reliability of the entire system. As one of the core components of an electric motor, the stator coil's shape accuracy, dimensional stability, and electrical performance have a crucial impact on the quality of the motor.

[0003] Existing technology discloses a stator coil shaping machine (publication number CN204858898U). The key technical points are: it includes a worktable with a first fixture and a second fixture. The first fixture includes a base slidably connected to the worktable and a first driving mechanism for sliding the base. The base has a rotating shaft for inserting a stator body, connected to a motor that drives its rotation. A shaping mechanism for trimming the coil is also provided on the edge of the rotating shaft on the worktable. The second fixture includes a lower mold for placing the coil and an upper mold for pressing the coil. The upper mold is also connected to a second driving mechanism for sliding. This invention solves the problem of poor shaping effect of existing stator coil shaping machines.

[0004] The aforementioned stator coil shaping machine can place the stator body on the lower mold base, and then the second drive mechanism drives the upper mold base to press and shape the stator body. The shaping effect of the coil coil is better through the joint shaping of the first and second tooling. However, the above device only sets a limit mechanism at the bottom when placing the stator body, and there is no fixing component at the middle and upper ends. The shaping accuracy is poor and the effect is not good when using it. This needs to be improved. Utility Model Content

The connecting frame 301 is fixedly connected to both sides of the inner wall of the frame 2. The limiting horizontal plate 302 is fixedly connected to the end of the connecting frame 301 away from the inner wall of the frame 2. The first hydraulic telescopic rod 304 is fixedly connected to the back side of the side end of the connecting frame 301. The limiting slider 303 is fixedly connected to the front side of the first hydraulic telescopic rod 304. The hydraulic cylinder 305 is fixedly connected to the side of the limiting slider 303. The intermediate connecting piece 306 is fixedly connected to... On the side of the hydraulic cylinder 305, the pressing plate 307 is fixedly connected to the right side of the intermediate connecting piece 306, the elastic ring pad 308 is fixedly connected to the right side of the pressing plate 307, the connecting strip 309 is fixedly connected to the inner wall of the elastic ring pad 308, and the suction cup 310 is fixedly connected to the side of the connecting strip 309. The center of the elastic ring pad 308 has rectangular grooves at the upper and lower ends. The width of the connecting strip 309 is adapted to the width of the rectangular grooves. The suction cups 310 are distributed in a longitudinal row at equal intervals on the right side of the connecting strip 309. The hydraulic cylinder 305 is activated to press the suction cups 310 onto the side of the stator coil, thereby achieving adsorption and fixation. Fixing components can be set at the upper and middle ends, and the precision during shaping is high.

[0026] The bottom clamping device 4 includes a second hydraulic telescopic rod 401, a U-shaped frame 402, an inner connecting plate 403, an arc-shaped plate 404, an airbag 405, a connecting air pipe 406, an air pump 407, and a delivery air pipe 408. The second hydraulic telescopic rod 401 is fixedly connected to the left side of the bottom inside the frame 2. The U-shaped frame 402 is fixedly connected to the right side of the second hydraulic telescopic rod 401 and slidably connected to the bottom inside the frame 2. The inner connecting plate 403 is fixedly connected to the inner ring of the U-shaped frame 402. The arc-shaped plate 404 is fixedly connected to the inner wall of the inner connecting plate 403.

Once inflated, the airbags 405 can squeeze and clamp the stator coil, providing a limiting and fixing position near the bottom. This initially secures the stator coil, facilitating subsequent processing. A side-end limiting device 3 is provided at the center position, which can adjust the position of the center pressing point back and forth. By activating the first hydraulic telescopic rod 304, the limiting slider 303 can be moved back and forth to adjust the position of the pressing plate 307. After adjusting to the appropriate limiting point, stop. Then, the hydraulic cylinder 305 can be activated to move the intermediate connecting piece 306 and the pressing plate 307 towards the center of both sides of the stator coil. Continue moving until the side of the suction cup 310 contacts the side of the stator coil. Then, continue to activate the hydraulic cylinder 305 to press the suction cup 310 against the side of the stator coil, thereby achieving adsorption and fixation. This device not only has a limiting mechanism at the bottom when placing the stator body, but also a fixing component at the middle and upper ends. It has high precision during shaping and good performance during use.
