Specific embodiment
Below in conjunction with Figure of description, technical scheme is described in further detail.
As shown in Figure 1, 2, a kind of stator core construction of default sub-motor, including the circle punching being made up of punching sheet unit 1
Piece, punching sheet unit 1 includes the tooth 101 located at circular punching periphery, the tooth yoke 103 located at circular punching inner circumferential, tooth connection 101 and
The denticle 102 of tooth yoke 103, is groove position 3 between adjacent denticle 102, and circular punching includes the first punching and the second punching, the first punching
Piece is located at iron core upper end, middle part and lower end three position, the tooth yoke between the first punching and the adjacent punching sheet unit 1 of the second punching
103 disconnections, the tooth 101 between the adjacent punching sheet unit 1 of the first punching is connected by cross structure 4, and the second punching laminates located at upper
At three stating between the first punching, the tooth 101 of the adjacent punching sheet unit 1 of the second punching is separated, between the first punching, first punching
Axially all laminated by keeper positioning between piece and the second punching, between the second punching.
In order to adapt to core structure intensity and the electrical characteristic of different-diameter and height, the first punching iron core upper end, in
The quantity that laminates of portion and lower end is multi-disc.According to the difference of iron core diameter and height, can reasonably adopt the folded of the first punching
Pressure quantity, is allowed to meet the electrical characteristic of iron core.
Positioning when laminating for convenience, keeper is 2 circular positioning convex 104, is respectively arranged on punching sheet unit 1 radially
Chi E 103 center of centrage and tooth 101 are connected with denticle 102 center at position.By positioning convex 104 is arranged at punching
On the centrage of unit 1 radial direction, make the overall balance of structure and electric stability preferable.By positioning convex 104 is arranged
On the centrage of punching sheet unit 1 radial direction, make the overall balance of structure and electric stability preferable.
As shown in Fig. 2 flinging the edge rolling of piece 5 for convenience, the width of cross structure 4 is the side of 4 tooth connections 101 of cross structure
The 1/3 of end width.The narrower width of cross structure 4, reduces inhibition when flinging piece edge rolling.
In order to lift electric property and be easy to Optimal Layout, all disconnect between the tooth 101 of the adjacent punching sheet unit of the second punching 1.
The tooth 101 disconnecting not only can lift electric property, and facilitates nesting optimization during punching, can lift the utilization effect of material
Rate.
Manufacture method process is as follows:
1) as shown in Figure 3,4, the first punching and the second punching are carried out with the discharge design of material strip 6, according to the first punching
Feature is designed to rectilinear first and flings piece 5, and be also arranged in a straight line shape to the punching sheet unit 1 of the second punching, forms second straight
Punching 7, then flings piece 5 and second and flings piece 7 and carry out punching press off-chip to first；
2) positioned by positioning convex 104, first laminate iron core lower end first flings piece 5, then flinging root on piece
Position according to positioning convex 104, laminate second and fling piece 7, laminate first again at the middle part of iron core and fling piece 5, then in the core
The first of portion flings and laminates second on piece 5 and fling piece 7, finally laminates first on iron core top and flings piece 5；
3) coiling is carried out to the punching after laminating；
4), after the completion of coiling, carry out edge rolling to flinging piece；
5), after the completion of edge rolling, by first, the connected position of piece 5 edge rolling is flung to the first punching and is welded and fixed.After edge rolling
The first punching as shown in Figure 1.
In this example, after the first punching and the second punching carry out rectilinear discharge design, first to fling piece 5 or the second straight
Groove position 3 width between the adjacent punching sheet unit 1 of punching 7 is more than the width of tooth yoke 103, and first flings piece 5 or the second flings piece 7
Spacing between the tooth yoke 103 of the adjacent punching sheet unit 1 of upper each two is more than denticle 102 width, is easy in the design of material strip 6 discharge
The tooth 101 flinging piece one and tooth yoke 103 are inserted in the groove position 3 that another flings piece, realize 2 symmetrical mistakes flinging piece
The interspersed arrangement in position, is capable of the utilization rate of almost lifting material strip 6 at double, greatly reduces material cost.
In this example, the first two ends flinging piece 5 are provided with the concavo-convex slot structure 2 of corresponding dove tail shape.Structure connects
Stable, lateral displacement will not occur.
The stator core construction of a kind of default sub-motor shown in figure 1 above -4 is the specific embodiment of the present invention,
Embody substantive distinguishing features of the present invention and progress, shape can be carried out to it according to actual use needs under the enlightenment of the present invention
