For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0037] Please refer to Figures 1-5 As shown in the drawings, in order to provide a limiting structure in the winding process, to ensure that the coil is wound according to the predetermined path, so as to achieve the formation of the required coil structure shape, the present application provides a winding limiting sleeve 1, the winding limiting sleeve 1 comprises a disk body 11, a first boss 12 and a second boss 13, wherein:
[0038] The disc body 11 is the main structural part of the winding limiting sleeve. The disc body 11 provides a stable platform for fixing the coil and guiding the winding. For this purpose, a first inclined wedge groove 111 is formed on the outer periphery of the disc body 11 to a certain depth, which is used to guide the lead wire to enter or exit the disc body along a specific inclined surface, so as to control the winding angle and direction of the lead wire, and ensure that the lead wire is uniformly and orderly wound. The first boss 12 is coaxially and integrally connected to one side surface of the disc body 11, and the second boss 13 is coaxially and integrally connected to the other side surface of the disc body 11. The two bosses are coaxially and integrally connected to the two sides of the disc body 11, which are mainly used to separate adjacent winding limiting sleeves 1 or spacer sleeves, prevent mutual influence during winding, and serve as the starting and ending support positions of the lead wire to provide additional support points during winding to prevent the lead wire from sliding or shifting. The center of the disc body 11, the first boss 12 and the second boss 13 is vertically penetrated by an expansion mandrel mounting hole 14. The expansion mandrel mounting hole 14 is used to install the expansion mandrel, which can be expanded during the winding process to fix the coil and prevent it from loosening. One end of the first inclined wedge groove 111 extends to the outer edge of the first boss 12, and the other end extends to the outer edge of the second boss 13. The purpose of this design is to help the lead wire smoothly transition from one side of the disc body 11 to the other side while maintaining the tension and position of the lead wire, thereby fixing the required structural shape.
[0039] Therefore, by designing the first inclined wedge groove 111, the winding path and angle of the lead wire can be accurately controlled, which is very important for ensuring uniform winding and reducing lead wire damage. The combination of the first boss 12 and the expansion mandrel can improve the stability of the cable and prevent it from shifting or loosening during winding. The expansion mandrel installed in the vertically penetrating expansion mandrel mounting hole 14 can adapt to coils of different diameters, improving the versatility of the winding limiting sleeve.
[0040] Specifically, as shown in Figure 1 , the central cross-sectional angle of the first inclined wedge groove 111 and the disc body 11 is 30 degrees.
[0041] Specifically, as shown in Figure 1 , 3 , the expansion mandrel mounting hole 14 is a square structure. The square structure can provide uniform stress distribution to ensure that the expansion mandrel remains stable during installation and operation. In addition, the square geometry makes the restraining force of the expansion mandrel equal in four directions, which helps to reduce wear or damage caused by uneven stress. Furthermore, the four corners of the square structure are provided with arc-shaped transition grooves 141, which can reduce stress concentration, especially at the edges of the expansion mandrel mounting hole 14. The arc-shaped transition can smoothly disperse the force, reducing the generation of material fatigue and cracks caused by stress concentration, making the installation and removal of the expansion mandrel more smooth, and improving the convenience of maintenance and operation.
[0042] Specifically, as shown in Figure 1 、 2 , the first boss 12 and the second boss 13 are both square structures with the same structure, which can provide better stability and carrying capacity, reduce structural deformation under high load, and thus improve the durability and reliability of the entire winding limiting sleeve. The first straight groove 121 is provided between the first inclined wedge groove 111 and the arc-shaped transition groove 141 at one end of the first boss 12, and the first straight groove 121 is parallel to the edge of the first boss 12; the second straight groove 131 is provided between the first inclined wedge groove 111 and the arc-shaped transition groove 141 at the other end of the second boss 13, and the second straight groove 131 is parallel to the edge of the second boss 13.
[0043] Thus, in order to achieve smooth transition of the wire from the inclined wedge groove to the straight groove, or to provide sufficient space to accommodate the wire or components during assembly, reduce bending stress during winding, protect the wire from damage, and also provide convenience for assembly and maintenance.
[0044] In addition, the design of the straight groove parallel to the edge of the boss helps to maintain the straight movement of the wire, reduces friction and wear caused by angle changes, improves the winding efficiency and quality of the wire, reduces cable damage caused by friction, and prolongs the service life of the coil.
[0045] Specifically, as shown in Figure 1 、 2 , to fix and limit the position of the wire during winding and ensure that the wire is wound according to the predetermined path, an inverted first hook groove 1111 is provided on each side of the first inclined wedge groove 111 near the first straight groove 121 and the second straight groove 131, respectively. The first hook groove 1111 is suitable for hooking the wire to prevent the wire from shifting or relaxing during winding, thereby improving the stability and uniformity of the winding.
[0046] In addition, the design of the inverted hook groove makes it easier to install and adjust the wire, as the hook groove can securely fix the wire, making it easier for the operator to adjust the tension and position of the wire.
[0047] Specifically, as shown in Figure 1 、 2 , the outer circumference of the disc body 11 is chamfered on both sides. The chamfering is mainly to improve the overall aesthetics of the part and to some extent eliminate burrs on the part. In addition, chamfering can enhance the overall mechanical strength to some extent, avoiding the inconvenience of later installation due to excessive stress concentration inside the part.
[0048] Specifically, as shown in Figure 1 、 2As shown, the first boss 12 is provided with a first cam spindle mounting hole 122 on one side of the first straight groove 121, and the first cam spindle mounting hole 122 and the first straight groove 121 are respectively located on the same side of the first boss 12.
[0049] In this embodiment, the first cam spindle mounting hole 122 is designed for installing and inserting the cam spindle 2. The cam spindle 2 is used to install the cam 3. The rotation of the cam 3 can press the starting part of the wire winding onto the winding spacer 4 on one side of the winding limit sleeve 1 to achieve precise positioning and fixation of the wire.
[0050] Specifically, please refer to Figure 1 , 3 As shown, a torsion spring limiting hole 112 is also provided on the disc body 11 near the first cam spindle mounting hole 122.
[0051] In this embodiment, the torsion spring limiting hole 112 is designed to install the torsion spring 5. The torsion spring 5 restricts or positions the movement of the cam 3 on the cam spindle 2 through its elastic deformation, so as to ensure that the upper cam 3 moves in a predetermined position or path to press and fix the starting part of the wire.
[0052] Specifically, please refer to Figure 1 , 2 As shown, the first straight groove 121 and the second straight groove 131 are arranged perpendicularly to each other. This design is usually used to provide two independent guide or positioning planes to achieve precise mechanical fit and motion control, ensuring independent operation in different directions without interference.
[0053] Please see Figure 5 As shown, this embodiment of the invention also provides a winding limiting sleeve assembly, including a plurality of winding limiting sleeves 1 as described above, wherein the plurality of winding limiting sleeves 1 are coaxially parallel and arranged side by side on the expansion mandrel.
[0054] Therefore, the coaxially parallel winding limiting sleeve 1 can wind multiple wires simultaneously, significantly improving production efficiency. This design allows for automation and mass production, reduces manual intervention, and lowers production costs.
[0055] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this invention.
