Embodiment
It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the application can phase
Mutually combination.Describe the present invention in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
In the prior art, it is necessary to first carry out enamel-covered wire (copper cash) by corresponding winding mould in stator production
Winding operation, stator coil is formed, then stator coil is enclosed on line of fall cup according to technical drawing requirement, if stator coil fills
Mistake will influence motor performance.Now, line of fall cup is aligned to the upper end of coil inserting apparatus gun barrel, then stator coil is lowered into rule
In the circular arc bar being vertically arranged of machine gun cylinder, line of fall cup is taken away.Hereafter, the upper end of the gun barrel then by stator core is placed on, in order to
Prevent rule process from slandering line and contacted, it is necessary to which stator core is had into slotted inner side with gun barrel, i.e., stator core is set in big gun
The upper end of cylinder.Starting switch is pressed, coil inserting apparatus is started working.Now, the coil inserting apparatus in coil inserting apparatus gun barrel, which is cut somebody's hair, understands along gun barrel
Motion upwards, at stator coil the coil can be driven to move up in stator core when this cuts somebody's hair to reach, and make stator coil
In the groove of embedded stator core, so as to complete stator built-in line.After stator built-in line is completed, it is also necessary to again by polishing, wiring,
The processes such as scolding tin, wiring, shaping, performance test and dipping lacquer complete stator manufacture, and it is whole finally to carry out stator injection completion with BMC material
The making of individual plastic packaging stator.
At present, the structure of iron-shell motor and the assembly method of motor are (when stator is set on rotor from non-lead end
Start to be arranged) determine that stator lead end-coil internal diameter is bigger than non-lead end-coil internal diameter, so can just prevent in assembling process
Rotor is damaged stator coil.However, in plastic packaging stator manufacturing process, only guaranteed stator lead end-coil internal diameter is than non-lead
Small winding (the non-lead end of stator that could meet Shooting Technique requirement, avoid plastic packaging stator injection molding end cover port of end-coil internal diameter
Coil) it is exposed.Specifically, as shown in figure 1, the iron core 1 of stator is set in injection core 2, injection core 2 has and iron core 1
The limited step 3 being engaged, the limited step 3 are stuck on the lower surface of iron core 1 to prevent iron core 1 from moving.Now, on iron core 1
Coil on end face is lead end-coil 4, and the coil on the lower surface of iron core 1 is non-lead end-coil 5.Due to being molded from injection molding end
Cover port (at non-lead end-coil 5) starts, in order to ensure that non-lead end-coil 5 will not be exposed, it is necessary to which empty avoiding is molded after being molded
The limited step 3 of core rod 2, this just needs the internal diameter of non-lead end-coil 5 bigger than the internal diameter of lead end-coil 4.It is if non-lead
The internal diameter of end-coil 5 it is smaller than the internal diameter of lead end-coil 4 just can not empty avoiding limited step 3, so as to can cause injection after stator it is non-
Lead end-coil 5 is exposed.
When carrying out coiling using existing winding mould, the circumference of coiling main body of the enamel-covered wire along winding mould is twined
Around so as to form stator coil.Therefore, the shape of the size decision coiling main body circumference profile on each side of coiling main body, and around
The shape of line main body circumference profile determines the shape of stator coil again.The coiling main body of existing winding mould includes upper and lower two
Point, wherein, upper part has two longitudinal edges be arrangeding in parallel and the first horizontal edge being connected between two longitudinal edges, lower part
With two hypotenuses be arrangeding in parallel and the second horizontal edge being connected between two hypotenuses, the length of the first horizontal edge is more than the
Two horizontal edges.Two longitudinal edges are connected respectively with two hypotenuses, and have angle between longitudinal edge and hypotenuse, i.e., stator coil is vertical
Side and the junction of hypotenuse form coil bending position.
When carrying out rule to stator coil, in order to ensure that rule process does not break, generally require and coil inserting apparatus is cut somebody's hair pair
Accurate above-mentioned coil bending position, by promoting the coil bending position to drive whole stator coil movement from the side of stator core
Opposite side is moved to, so that coil is imbedded in the groove of stator core.In above process, corresponding to coiling lower body part point
The non-lead end that coil is pushed to stator core forms non-lead end-coil, corresponding to coiling body top point coil then
Lead end-coil is formed in the lead end of stator core.If it is desired that non-lead end-coil internal diameter is sufficiently large after rule, just
Need to try one's best the coil of the coiling lower body part point non-lead end face of more past stator cores pushes away, so, when above-mentioned line
Circle bending position will also push ahead a segment distance by force again after shifting position onto, and this will make the straight line push-pull effort increasing to coil
Greatly, so as to easily cause coil breakage, coil breakage fraction defective is up to 30%, and occurs after stator placement in stator coil
The phenomenon of footpath resilience, there is naked wire after so will also result in injection.Therefore, the solution non-lead end-coil internal diameter of determinant is small in industry
Method only by lengthening winding coil girth, so as to adjust coil global design scheme, and can so increase raw material, enter
And increase cost.
During to stator built-in line, the circular arc bar on coil inserting apparatus gun barrel is used for set winding, and coil inserting apparatus is cut somebody's hair for inciting somebody to action
Coil on gun barrel circular arc bar is promoted in the groove of stator core.Therefore, (do not pushed away by force on the premise of ensureing that rule process does not break
Coil), the internal coil diameter size at stator core both ends depends on the position that coil imbeds stator core, and coil imbeds stator core
Position cut somebody's hair position depending on coil inserting apparatus, and coil inserting apparatus is cut somebody's hair, position depends on coil bending position, the coil bending position
Put the geomery of the coiling main body depending on winding mould.

When the distance between one base 21 and the 4th base 24 L3 are constant, make the junction and first on the second base 22 and the 3rd base 23
The distance between base 21 is sufficiently small, so that between the second base 22 and the junction and the 4th base 24 on the 3rd base 23
It is at a distance sufficiently large.Stator coil forms coil bending position in the junction on the second base 22 and the 3rd base 23, is ensureing line
In the case that circle does not break, coil inserting apparatus is cut somebody's hair and is directed at above-mentioned coil bending position, by promoting the coil bending position to drive
Whole stator coil movement is moved to opposite side from the side of stator core, so that coil is imbedded in the groove of stator core.
In said process, it is pushed to the non-of stator core corresponding to the coil on the 3rd base 23, the 5th base 25 and the 4th base 24 and draws
Line end forms non-lead end-coil, is then determining corresponding to the coil on the second base 22, the 6th base 26 and the first base 21
The lead end of sub- iron core forms lead end-coil.Due to the setting of the geomery of above-mentioned coiling main body 20, corresponding to
The coil on three bases 23, the 5th base 25 and the 4th base 24 is more, so that being formed after embedded stator core non-lead
The internal diameter of end-coil is larger, and then avoids stator from coil exposing phenomenon occur after being molded, and improves product qualification rate.Meanwhile use
When above-mentioned winding mould carries out coil winding, it is not necessary to which non-lead end-coil internal diameter, more supernumerary segment can also be increased by increasing coil girth
Material saving, production cost are low.Further, since the distance L3 between the first base 21 and the 4th base 24 is constant, the first base
21 and the 4th base 24 length it is constant, the distance between the junction and the first base 21 on the second base 22 and the 3rd base 23
Diminish, therefore, the angle increase between the second base 22 and the 3rd base 23.Above-mentioned angle increase can make rule more suitable
Freely, so as to reducing coil breakage.

Above-mentioned L2 sizes design according to stator stack thickness, i.e., the internal diameter size of the non-lead end-coil of stator and L2 sizes into
Inverse ratio.Only L2 sizes are sufficiently small, and the internal diameter of the non-lead end-coil of stator is just sufficiently large, could so ensure rule process not
On the premise of breaking, the internal diameter of the non-lead end-coil of stator is controlled.
In the acquisition methods of the present embodiment, acquisition methods also include:
The distance between the second base 22 and the 6th base 26 L1 is determined according to the cross-slot centre-to-centre spacing D2 of iron core.In the present embodiment
In, the distance between the second base 22 and the 6th base 26 L1 is obtained by below equation:
L1=D2=2 × R × sin θ;
Wherein, L1 is the distance between the second base 22 and the 6th base 26, as shown in figure 3, D2 is in the cross-slot of iron core 1
For the heart away from (quantity of specific groove is selected as needed), R is the groove of iron core 1 to distance (the i.e. iron core 1 of the axis of iron core 1
Internal diameter), θ is the half (half of the angle i.e. between the center line of the groove at both ends) of the angle between the cross-slot of iron core 1.
3rd base 23 and the 4th base 24 are determined according to the (not shown) of circular arc article width D 3 of coil inserting apparatus gun barrel
The distance between junction and the 5th base 25 and the 4th base 24 L4.In the present embodiment, the 3rd is obtained by below equation
The distance between the junction and the 5th base 25 and the 4th base 24 on the base 24 of base 23 and the 4th L4:
L4=D3+ (4.8~5.3) mm;
D3=D4+ (1~1.5) mm;
Wherein, L4 is between the 3rd base 23 and the junction and the 5th base 25 and the 4th base 24 on the 4th base 24
Distance, D3 is the circular arc bar width of coil inserting apparatus gun barrel, as shown in Fig. 2 D4 is cell wall width (the rule machine gun of the iron core 1 of stator
The circular arc bar width of cylinder is the notch groove design of iron core 1 according to stator).
The non-lead high H in end-coil end according to needed for the axial width D1 and iron core of iron core determines the first base 21 and
The distance between four bases 24 L3.In the present embodiment, it is derived by by following between the first base 21 and the 4th base 24
Distance L3:
Because L1, L2 and L4 are it has been determined that base perimeter L (i.e. stator coil girth)=L1+L4+ of coiling main body 20
2 × L2+2 × (L3-L2)/cos θ=L1+L4+2 × (D1+2mm)+2 × (L3-L2)/cos θ;
Wherein, L is the base girth of coiling main body 20, and L1 is the distance between the second base 22 and the 6th base 26, L2
