Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Reference Figures 1 to 3 This utility model provides an embodiment of a stacked, adjustable-thickness segmented stator coil winding fixture, including a fixture support plate 1. The fixture support plate 1 is the basic structure of the entire fixture, used to support and fix other components. A placement plate 2 is fixedly connected to the right end of the fixture support plate 1, used to place and fix the stator segments 11. A drive assembly is fixedly connected inside the placement plate 2, used to drive a push plate 4 to perform linear motion. The drive assembly includes a cylinder 3, which is the core component of the drive assembly and provides power. The cylinder 3 is externally fixedly connected inside the placement plate 2 to ensure the stability and robustness of the cylinder 3. The drive end of the cylinder 3 is fixedly connected to the push plate 4, which performs linear motion under the drive of the cylinder 3, pushing a rotating plate 5.
[0034] Rotating plates 5 are rotatably connected to both the upper and lower ends of the drive assembly. The rotating plates 5 rotate under the push of the push plate 4. The upper and lower ends of the push plate 4 are rotatably connected to the left ends of the two rotating plates 5, ensuring that the movement of the push plate 4 is effectively transmitted to the rotating plates 5. An opening plate 6 is rotatably connected to the right end of the rotating plates 5, and the opening plate 6 slides under the drive of the rotating plates 5. Strip plates 9 are fixedly connected to the opposite sides of the two opening plates 6, transmitting the sliding force to the strip plates 9 through the opening plates 6. A connecting plate 7 is fixedly connected to the right side of the strip plates 9, driving the connecting plate 7 to slide synchronously. A clamping plate 8 is fixedly connected to the right side of the connecting plate 7 for clamping. Two positioning posts 10 are slidably connected inside the two strip plates 9, ensuring the stable movement of the strip plates 9. The two positioning posts 10 are fixedly connected to the front and rear ends of the placement plate 2, ensuring the stability of the positioning posts 10.
[0035] Reference Figure 1 , Figure 4 and Figure 5 A stator block 11 is slidably connected to the right end of the placement plate 2. The stator block 11 is used to wind the stator coil. Side tooling plates 12 are bolted to both the upper and lower ends of the stator block 11. The side tooling plates 12 are used to fix and support the stator block 11. A connecting shaft 13 is fixedly connected to the right side of the side tooling plate 12. Multiple positioning plates 14 are fixedly connected to the front side of the tooling support plate 1, and are fixed by welding to provide support for the positioning plates 14. A rotating ring 15 is rotatably connected to the outside of the positioning plates 14, and the rotating ring 15 is used to restrict the copper wire. A sliding column 16 is slidably connected to the inner wall of the tooling support plate 1. The sliding column 16 can slide stably due to the restriction of the tooling support plate 1. A positioning ring 17 is fixedly connected to the outside of the sliding column 16, and is fixed by welding to provide support for the positioning ring 17. An adjusting ring 18 is rotatably connected to the outside of the positioning ring 17. The adjusting ring 18 can rotate stably due to the restriction of the positioning ring 17.
[0036] A sliding column 19 is slidably connected to the inner wall of the sliding column 16. The sliding column 16 restricts the sliding column 19, allowing it to slide stably. A reset assembly is fixedly connected to the outside of the sliding column 19, providing a reset force. The reset assembly includes a fixing ring 20, which is internally fixed to the outside of the sliding column 19 and secured by welding, allowing the sliding column 19 to drive the fixing ring 20 to slide synchronously. A spring 21 is sleeved on the outside of the sliding column 19, restricting the spring 21 and ensuring it receives uniform force. The front end of the spring 21 is fixedly connected to the rear side of the fixing ring 20. During sliding, the fixing ring 20 compresses the spring 21, allowing it to store elastic potential energy, which in turn provides a counterforce to the fixing ring 20 for reset.
[0037] The inner wall of the sliding column 16 is fixedly connected to the rear end of the spring 21, ensuring that the spring 21 can be evenly stressed. Two side plates 22 are fixedly connected to the rear end of the sliding column 19, driving the two side plates 22 to slide synchronously. A transmission column 23 is fixedly connected to the far side of each of the two side plates 22, transmitting the sliding force to the transmission column 23 through the side plates 22. A limit block 24 is slidably connected to the outside of the transmission column 23. An inclined opening 25 is provided inside the limit block 24, which guides and restricts the movement of the transmission column 23, thereby transmitting the sliding force to the limit block 24. The outside of the transmission column 23 is slidably connected inside the inclined opening 25, ensuring stable movement of the transmission column 23. Two rows of limit openings 26 are provided inside the front end of the tooling support plate 1, used to fix and restrict the movement of the limit block 24. The outside of the limit block 24 is slidably connected inside the limit opening 26, ensuring the stability and firmness of the limit block 24.
[0038] Working principle: The starting cylinder 3 pushes the push plate 4 to move linearly, which in turn drives the two rotating plates 5 to rotate, thereby driving the opening plate 6 to rotate. Then, the opening plate 6, under the restriction of the positioning post 10, drives the strip plate 9 to slide up and down, which in turn drives the connecting plate 7 to slide, thereby driving the clamping plate 8 to slide. At this time, the two clamping plates 8 will slide to the same side and fix the stator block 11. At the same time, by adjusting the distance between the two clamping plates 8, the stator block 11 of different heights can be adapted, thereby improving its flexibility.
[0039] Then, depending on the winding situation of the copper wire, the copper wire is wrapped around the left-end rotating ring 15, then around the upper rotating ring 15, then around the left end of the adjusting ring 18, and finally around the bottom rotating ring 15 and fixed to the connecting shaft 13. Then, depending on the required copper wire tension, the sliding column 19 is pushed to slide, which in turn drives the fixing ring 20 to slide and compress the spring 21, allowing the spring 21 to store elastic potential energy. This allows the fixing ring 20 to apply a force in the opposite direction to the sliding column 19 for resetting. During the sliding process of the sliding column 19, the two side plates 22 will slide, thus... The transmission column 23 is driven to slide, and finally the inclined opening 25 inside the limiting block 24 guides the limiting block 24 to slide, so that the transmission column 23 can slide the two limiting blocks 24 to the same side until it slides into the interior of the sliding column 16. At this time, the sliding column 16 can be pushed to the left, thereby driving the adjusting ring 18 to slide and abut against the copper wire, thereby achieving the effect of adjusting the tension of the copper wire. After the adjustment is completed, the pushing force on the sliding column 19 is released. At this time, the reset force of the spring 21 will be transmitted to the two limiting blocks 24 to reset, slide to the opposite side and engage inside the limiting opening 26.
[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
