Can the through type slot for winding electric machine iron core of direct coiling
Technical field
This utility model relates to a kind of electric machine iron core, especially relate to a kind of can the through type winding electric machine iron core of direct coiling.
Background technology
At present, stator iron core of vehicle generator is all the structure of big slot for winding and small-rabbet, because tooth extremely on be provided with teeth and cause notch the least formation small-rabbet structure, directly can not carry out coiling in the slot for winding of iron core, winding is all to first pass through spooling equipment to be wound in specific frock by enamel-covered wire, then is embedded in stator core by the enamel-covered wire being coiled into given shape by rule equipment.But after being increased by stator core notch, enamel-covered wire winding easily comes off from notch again.It is thus desirable to extra wire winding tool and expensive rule equipment, and complex procedures, production efficiency is difficult to promote.The most how appropriate design slot for winding and notch arrangement are the problems all the time needing to solve.
Utility model content
This utility model provide a kind of can the through type slot for winding electric machine iron core of direct coiling, enamel-covered wire can be directly wound in the slot for winding of stator core by it, can ensure that again enamel-covered wire winding will not be deviate from from winding notch well.
This utility model provide a kind of can the through type slot for winding electric machine iron core of direct coiling, including the multiple tooth poles being uniformly distributed circumferentially, winding slot is formed between adjacent teeth pole, tooth pole front end face extends outward two folding parts, left and right, two folding parts can form, to the winding slot bending fold of respective respective side, the teeth that tooth is extremely gone up, and the width of the teeth after folding is more than the Breadth Maximum of the extremely middle remainder of tooth.
Preferably, side, described tooth pole and the angle of tooth pole lengthwise centers line are within ± 10 °.
Preferably, side, described tooth pole and the angle of tooth pole lengthwise centers line are within ± 8 °.
Preferably, described tooth extremely front portion has interior concane gap, interior concane gap to be positioned at rear, folding part.
Preferably, described interior concane gap top grooved hole.
Preferably, described folding part and angle, the inner side grooved hole of tooth pole front end face.
This utility model novel structure, easy to use and reliable, stator core directly can be carried out coiling, can prevent enamel-covered wire winding from deviating from folding part folding with press after coiling, whole process operation is convenient and production efficiency is greatly improved, and has saved wire winding tool and inserting winding tool simultaneously, reduce extra operation and personnel, it is greatly saved cost, while ensureing quality, has started the precedent of whole industry, there is huge market value.

Detailed description of the invention
Below in conjunction with the accompanying drawings in order to this utility model is described in further detail.
As shown in Figures 1 to 6, this utility model provide a kind of can the through type slot for winding electric machine iron core of direct coiling, including the multiple tooth poles 1 being uniformly distributed circumferentially, winding slot 2 is formed between adjacent teeth pole 1, tooth pole 1 front end face extends outward two folding parts 3, left and right, two folding parts 3 can form the teeth 4 on tooth pole 1 to winding slot 2 bending fold of respective respective side, and the width of the teeth 4 after folding is more than the Breadth Maximum of remainder in tooth pole 1.
Preferably, the angle of side, described tooth pole 1 and tooth pole 1 lengthwise centers line is within ± 10 °, and i.e. from bottom, to top-direction, the most inside or toward outer incline, the angle of inclination is within 10 ° in two sides.
Preferably, the angle of side, described tooth pole 1 and tooth pole 1 lengthwise centers line is within ± 8 °, and i.e. from bottom, to top-direction, the most inside or toward outer incline, the angle of inclination is within 8 ° in two sides.
There is interior concane gap 5 front portion, tooth pole 1, interior concane gap 5 is positioned at rear, folding part 3, facilitates the flowing of core material in folding process, because ferrum has ductility, in folding process, core material there will be flowing, interior concane gap 5 arrange what the core material that can fill up unnecessary flowed towards this position.
Preferably, interior concane gap 5 top grooved hole 6, facilitate the folding of folding part 3.
Preferably, folding part 3 and angle, the inner side grooved hole 6 of tooth pole 1 front end face, facilitate the folding of folding part 3.
During concrete operations, directly by coil winding machine coiling on stator core, after coiling, stator core is put in mould, by press, folding part being folded toward both sides pressing, form stator core shape as shown in Figure 4, concrete fold line is not limited to two shown in Fig. 5 and Fig. 6 kind, whole process simple and fast, eliminate extra wire winding tool and expensive rule equipment, saved operation and cost of labor, significantly provided production efficiency.
Certainly; this utility model also can have other various embodiments; in the case of without departing substantially from this utility model spirit and essence thereof; those of ordinary skill in the art can make various corresponding change and deformation according to this utility model, but these change accordingly and deformation all should belong to the scope of the claims appended by this utility model.
