[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0021] Reference Figure 1-4A stator core automatic winding tool comprises a mounting ring 1 and a core body 3. As shown in the figure, the mounting ring 1 is also provided with a supporting leg 2, which is a conventional component to achieve effective support of the mounting ring 1. It can be welded and connected to the processing platform in the workshop and conveniently connected with the bolt assembly to ensure the stability of the mounting ring 1 when it is placed.
[0022] A plurality of limiting wheels 4 are arranged in the mounting ring 1. The vertical cross-section of the limiting wheels 4 is H-shaped. As shown in the figure, three limiting wheels 4 are arranged. The above-mentioned current design of the limiting wheels 4 realizes effective support and limiting of the core body 3, and can prevent it from horizontal displacement.
[0023] A plurality of rotating cavities 6 are provided inside the mounting ring 1, and a transmission cavity 7 is also provided inside the mounting ring 1. A screw 8 is provided for rotation inside the rotating cavity 6, and the limiting wheel 4 is connected to the screw 8 through a connecting mechanism. A transmission ring 11 is provided inside the transmission cavity 7 through a limiting mechanism. A driving motor 9 is provided inside the transmission cavity 7, and the driving motor 9 is connected to the transmission ring 11 through a rotating mechanism, and the transmission ring 11 is connected to the screw 8 through a transmission mechanism.
[0024] The connection mechanism includes a movable frame 5 threadedly mounted on the screw 8. The movable frame 5 is U-shaped and is rotatably connected to the limiting wheel 4. The movable frame 5 is U-shaped and both ends slide through the inner wall of the rotating cavity 6 and extend to the external position of the mounting ring 1. Therefore, it has its own limit to effectively avoid rotating with the screw 8.
[0025] The limiting mechanism includes a limiting ring 13 installed on the transmission ring 11, and an annular limiting groove corresponding to the limiting ring 13 is provided on the inner wall of the transmission cavity 7. The vertical cross-sectional views of the limiting ring 13 and the annular limiting groove are both T-shaped. With the help of the limiting ring 13 and the annular limiting groove, the transmission ring 11 is stabilized in the transmission cavity 7.
[0026] The rotating mechanism includes a driving gear 10 installed on the output shaft of the driving motor 9, and an outer gear ring meshing with the driving gear 10 is provided on the arc-shaped outer wall of the transmission ring 11. The transmission mechanism includes a transmission gear 12 installed on the end of the screw 8, and an inner gear ring is provided on the arc-shaped inner wall of the transmission ring 11. The transmission gear 12 meshes with the inner gear ring. The above-mentioned outer gear ring and inner gear ring are not specifically shown in the figure. The teeth of the outer gear ring are arranged on the arc-shaped outer wall and mesh with the teeth of the driving gear 10. Similarly, the teeth of the inner gear ring are arranged on the arc-shaped inner wall and mesh with the teeth of the transmission gear 12. Therefore, the power transmission of the driving motor 9 is finally realized, and the synchronous rotation of the three screws 8 can be achieved after the driving motor 9 is started.
[0027] When the utility model is in use, as shown in the figure, the core body 3 is located between the three limiting wheels 4, and the points where the limiting wheels 4 contact the core body 3 form a triangle, which can stably limit the core body 3, facilitate three-point support and limiting when winding the core body 3, prevent the core body 3 from moving randomly during the winding process, speed up the winding speed of the annular core body 3, and improve the efficiency of winding the annular core body 3.
[0028] In this solution, after starting the drive motor 9, the driving gear 10 can be driven to rotate. The driving gear 10 can be matched with the outer gear ring to drive the transmission ring 11 to rotate in the transmission cavity 7. The transmission ring 11 can be matched with the inner gear ring to drive the transmission gear 12 to rotate. The transmission gear 12 can drive the screw 8 to rotate. When the screw 8 rotates, the movable frame 5 threadedly mounted on it can drive the limiting wheel 4 to move, and finally the spacing between the three limiting wheels 4 can be adjusted, so that the tooling of this solution can adapt to the core body 3 of various sizes for three-point support and limitation within a certain range.
[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
