[0015] Preferably, one side of the winding plate is provided with a second positioning column, and the other side of the winding plate is provided with a second positioning groove, and the second positioning column is arranged in the second positioning groove of the adjacent winding plate.

[0021] Preferably, the side of the positioning plate away from the first sheet body is provided with a circular arc shape.

DETAILED DESCRIPTION

[0033] The following will be described in conjunction with the drawingsFigures 1-5 The application is further described in detail.

[0034] Embodiment one of the application discloses a stator core facilitating winding.

[0035] Embodiment one of the application discloses a stator core facilitating winding. Referring to Figure 1 and Figure 2 , the stator core facilitating winding comprises a plurality of punching plate bodies 1, each of which is superimposed. The punching plate body 1 comprises a plurality of first plate bodies 11 connected in a head-to-tail manner, and the two adjacent first plate bodies 11 are abutted and connected through a connecting plate 2. Each first plate body 11 is fixed with a winding plate 12 for winding, and the winding plate 12 is connected with a second plate body 13 away from the first plate body 11, and there is a gap between the two adjacent second plate bodies 13. The worker expands the first plate body 11 and expands the gap between the two adjacent second plate bodies 13, so as to wind the enameled wire on the winding plate 12, which reduces the phenomenon of jamming in the winding process, thereby improving the winding efficiency of the punching plate body 1.

[0036] Referring to Figure 1 and Figure 2 , the connecting plate 2 is provided with an arc-shaped hole 21 at the connection with the first plate body 11, and the arc-shaped hole 21 is combined into a circular hole 3 after the abutment of the two adjacent first plate bodies 11. The circular hole 3 facilitates the worker to expand each first plate body 11, and the circular hole has good ductility, so that the first plate body 11 is not easy to break when it is in an expanded state, which provides convenience for the worker to wind.

[0037] Referring to Figure 1 , in order to facilitate the head-to-tail connection of each first plate body 11, the first plate body 11 at the head end is fixed with a clamping plate 111, the first plate body 11 at the tail end is provided with a clamping hole 112, and the clamping plate 111 is arranged in the clamping hole 112. After the enameled wire is wound, the worker abuts each first plate body 11, and then clamps the clamping plate 111 into the clamping hole 112, thereby completing the head-to-tail connection of each first plate body 11.

[0038] Referring to Figure 2 , one side of the first plate body 11 is provided with a first abutment surface 113, and the other side is provided with a second abutment surface 114, and the first abutment surface 113 abuts with the second abutment surface 114 of the adjacent first plate body 11. The first abutment surface 113 and the second abutment surface 114 increase the contact area between the two adjacent first plate bodies 11, so as to determine the position between the two adjacent first plate bodies 11.

[0039] Referring to Figure 1 and Figure 3, in order to facilitate the superposition of the two adjacent punching piece bodies 1, one side of the first piece 11 is fixed with a first positioning column 115, and the other side of the first piece 11 is provided with a first positioning groove 116 matched with the first positioning column 115, and the first positioning column 115 is arranged in the first positioning groove 116 of the adjacent first piece 11.

[0040] And one side of the winding plate 12 is fixed with a second positioning column 121, and the other side of the winding plate 12 is provided with a second positioning groove 122, and the second positioning column 121 is arranged in the second positioning groove 122 of the adjacent winding plate 12.

[0041] When the first pieces 11 need to be superposed, the workers insert the first positioning column 115 into the corresponding first positioning groove 116, and at the same time, the second positioning column 121 is inserted into the corresponding second positioning groove 122, so as to determine the position between the adjacent two first pieces 11 and the adjacent two winding plates 12, thereby improving the position accuracy between the adjacent two punching piece bodies 1 and providing convenience for subsequent winding of the enameled wire.

[0042] The implementation principle of the embodiment one of the application is that when the enameled wire needs to be wound on the winding plate 12, the workers unfold each first piece 11, and then superpose the adjacent two first pieces 11. At this time, the gap between the adjacent two second pieces 13 is enlarged, so as to reduce the phenomenon of wire breakage or jamming in the winding process. After the winding of the enameled wire on the winding plate 12 is completed, the workers abut the adjacent two first pieces 11, so that each first piece 11 is connected end to end, the winding of the enameled wire is completed, thereby providing convenience for the winding of the enameled wire on the punching piece body 1.

[0043] Embodiment two

[0044] Referring to Figure 4 and Figure 5 The difference between the embodiment one and the embodiment two is that one side of the first piece 11 is fixed with a plurality of positioning plates 4, the other side of the first piece 11 is provided with a plurality of positioning holes 117, each positioning plate 4 corresponds to one positioning hole 117, and the positioning plate 4 is arranged in the positioning hole 117 of the adjacent first piece 11. And the side of the positioning plate 4 away from the first piece 11 is arranged in a circular arc shape.

[0045] Referring to Figure 4 and Figure 5In order to improve the connection stability between the two adjacent first pieces 11, the positioning plate 4 is provided with a plurality of positioning protrusions 41, the first piece 11 is provided with a plurality of limiting holes 118, each limiting hole 118 corresponds to a positioning protrusion 41, and the positioning protrusion 41 is arranged in the limiting hole 118 at the corresponding position. And the positioning protrusion 41 is arranged in a circular arc shape, and the circular arc-shaped positioning protrusion 41 is convenient to be clamped into the limiting hole 118 at the corresponding position after slight deformation. At the same time, under the action of the positioning protrusion 41, the contact area between the two adjacent first pieces 11 is increased, thereby improving the connection stability between the two adjacent first pieces 11.

[0046] The implementation principle of the second embodiment of the present application is that the positioning plate 4 cooperates with the positioning hole 117 at the corresponding position to facilitate determining the position between the two adjacent first pieces 11, further improving the position accuracy between the two adjacent first pieces 11, and reducing the possibility of deviation between the two adjacent first pieces 11. At the same time, since the end of the positioning plate 4 is arranged in a circular arc shape, the positioning plate 4 is not easy to cause damage to the adjacent first piece 11.

[0047] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, therefore: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
