Description
Technical field
The present invention relates to a kind of fixing means of coil-end of the both ends of the surface that protrude in stator core.In more detail, relate to a kind of can be when the coil-end of stator be tightened, do not form toe-in and the fixing method of coil end of the stator of fixed coil end.
Background technology
Constitute the stator of parts as motor, in being formed at each groove of stator core, coil is installed and is formed.On stator, form as the coil-end of coil from the outstanding part of the both ends of the surface of stator core.This coil-end may contact with rotor or housing when constituting motor.Therefore,, make it bundle together, implement japanning thereafter and handle and the fixed coil end with line harness coil-end (tightening) by so-called.
Wherein, by litzendraht wire and coil-end is seamed into mesh-shape tightens.To be seamed into cancellous part lax in order to make, and need suitably handle beginning suture and seam tie lines.For example shown in Figure 20 in the past, by the handwork harness from beginning suture 9s that coil-end 2 is exposed and seam tie lines 9e, so that the line 9 of tightening can not be untied.If yet to handle by handwork like this, productivity is very poor.
Therefore in recent years, in order to improve productivity, use by the interaction of nozzle and hook begin automatically suture and seam tie lines processing tighten device.As this device of tightening, for example have and open disclosed device in the flat 2-214445 communique the spy.
Tighten in the device at this, as shown in figure 21, the beginning, suture 9s sewed up processing together when coil-end 2 is tightened.In addition, following the carrying out of processing of seam tie lines 9e.Just after coil-end 2 is tightened, form circle R, in this circle R, insert hook, drag wire retreats by circle R hook and pulls out seam tie lines 9e, and the line 9e that is drawn out is kept further tension by clamp again, thus, as shown in figure 22, the opposite joint tie lines 9e processing of tiing a knot.
If use this to tighten device beginning suture 9s and seam tie lines 9e are handled, then as shown in figure 22, at the knotting place formation toe-in 10 of seam tie lines 9e.If form such toe-in, this toe-in may cause defective insulation with the housing interference of motor when forming motor.This neither insulate fully because of line, also has conductivity to a certain degree.This conductivity has dependence to temperature and environment, under electric motor for vehicle like that at high temperature is dipped in situation in the oil (ATF), obviously has the tendency that conductivity improves.Therefore, when requiring miniaturization in the electric motor for vehicle of environment for use strictness, because the coil-end of stator and the gap of housing have only several mm, thereby toe-in causes the possibility of defective insulation bigger with the housing interference.Even, also can form toe-in, thereby the problems referred to above also occur by handwork harness beginning suture 9s and seam tie lines 9e.
Therefore, in order not form such toe-in, for example open the fixing method of coil-end that has proposed a kind of not tightening in the 2002-218718 communique and carried out stator the spy.The method is characterised in that, to the both ends pressurization to coil of the axis direction of stator, keeps the state of compression, simultaneously above-mentioned overhang (coil-end) carried out japanning and handles.Thus, can reduce the overhang of coil-end as possible, and not need to carry out tightening of harness coil-end from stator.
Yet open in the method that proposes in the 2002-218718 communique the spy,, carry out the fixing of coil-end, thereby have the inadequate problem of fixing possibility of coil-end owing to only handle by japanning though do not produce toe-in owing to not tightening.This is that near the temperature the coil-end can become very high because when using motor, and lacquer may soften.If lacquer is softening, because the resilience of coil etc., the overhang of coil-end may increase.Like this, coil-end contacts with the housing of motor and causes defective insulation.Therefore, in order to guarantee the reliability of motor fully, need after harness coil-end, carry out japanning and handle, and coil-end is fixed by tightening.
Summary of the invention
Therefore, the present invention makes in order to address the above problem a little, and its purpose is to provide a kind of fixing method of coil end of stator, can be when the coil-end of stator be tightened, and do not form toe-in and firmly fix coil-end.
In order to solve the above problems, the fixing method of coil end of stator of the present invention, coil-end to the both ends of the surface that protrude in stator is fixed, it is characterized in that, above-mentioned coil-end is tightened, at the circle of above-mentioned last formation of tightening and the circle of its previous formation, by itself not forming the seam tie lines tractive of ring, after carrying out simple and easy knotting, under the state of the simple and easy knotting of seam tie lines, above-mentioned coil-end is carried out japanning handle.
In the fixing method of coil end of this stator, litzendraht wire also is seamed into mesh-shape with coil-end and tightens.The coil-end of stator is with identical in the past thus, and harness is fixed by tightening.Carrying out this when tightening, the beginning suture also sews up coil-end.To at the circle of the last formation of tightening and the circle of its previous formation, by seam tie lines tractive, carry out simple and easy knotting, stitch tie lines and handle.Therefore do not form toe-in in knotting place.
Yet under this state, simple and easy toe-in may be untied.Therefore for simple and easy toe-in can not untied, under the state of the simple and easy knotting of seam tie lines, carry out japanning and handle.Thus, can reinforce the part of simple and easy knotting, thereby can prevent that simple and easy toe-in from untiing.Like this, in the fixing method of coil end of this stator, the coil-end of stator is not tightened, and implement japanning and handle, thereby can firmly fix coil-end owing to do not form toe-in.
In the fixing method of coil end of stator of the present invention, expectation is carried out above-mentioned tightening and above-mentioned simple and easy knotting by the nozzle and the tractive mutual action of the hook of the line of nozzle supply thus of supply line to above-mentioned coil-end.
The coil-end of stator is tightened and simple and easy knotting also can be undertaken by handwork, but productivity is poor.Therefore,, and coil-end is tightened and simple and easy knotting, can make these operation automations, improve productivity by the nozzle and the tractive mutual action of the hook of the line of nozzle supply thus of supply line.

Embodiment
Below the preferred forms of with reference to the accompanying drawings fixing method of coil end that makes stator of the present invention being specialized is described in detail.The fixing method of coil end of the stator of present embodiment comprises treatment process and the japanning treatment process with the operation of the coil-end harness ramify shape of stator, seam tie lines substantially.These operations are described in turn.
At first describe tightening operation.The summary of tightening operation is represented in Fig. 1.In tightening operation, as shown in Figure 1, make stator 1 each angle of rotating regulation, by can on the direction of principal axis of said stator 1, moving, and the nozzle 5 of supply line and can on the direction of principal axis of said stator 1 and radial direction, moving, and the mutual action of the hook 4 of the line of above-mentioned nozzle 5 supplies of tractive, and to tightening from the outstanding coil-end 2 of the both ends of the surface of stator core 3.
Then the order that the coil-end 2 of this stator 1 is tightened is described with reference to Fig. 2～Figure 17.Coil-end 2 is because outstanding from the both ends of the surface of stator core 3, though thereby also two coil-end are tightened because any one coil-end is all tightened with identical order, therefore here only tightening in proper order of a coil-end described.
At first, as shown in Figure 2, nozzle 5, be positioned at coil-end 2 above state under, from nozzle 5 supply lines 9.The front end of the line of being supplied with by nozzle 59 is kept by pin 7, and the line of being supplied with by nozzle 59 is tightened up and opens and establish.
Under this state, as shown in Figure 3, nozzle 5 just moves to the inside of stator core 3 to the below of coil-end 2.Nozzle 5 keeps the mouth maintaining part 6 of nozzle 5 axially to move by making.Hook 4 extends to the radial direction inboard of stator core 3.This hook 4 passes from the bottom (between coil-end 2 and the stator core 3) of coil-end 2, moves to the position that engages with line 9.
Thereafter, hook 4 at its front end drag wire 9, retreats to the radial direction outside of stator core 3 as shown in Figure 4, pulls out line 9 from the bottom of coil-end 2.
Then, as shown in Figure 5, hook 4 is moved upward by the outside of coil-end 2 under the state of front end drag wire 9.Thus, form circle R1 on online 9.At this moment, nozzle 5 also is moved upward.
Then, as shown in Figure 6, hook 4 extends to the radial direction inboard of stator core 3 once more.At this moment, hook 4 is by the top of coil-end 2, and its front end enters the inboard of stator core 3, the line 9 that tractive is supplied with by nozzle 5.
Thereafter, as shown in Figure 7, hook 4 its front end drag wires 9 retreat by circle R1 to the radial direction outside of stator core 3.Form circle R2 on online thus 9.
Then, as shown in Figure 8, hook 4 moves downwards by the outside of coil-end 2 under the state of front end drag wire 9.Thus, will enclose R2 and pull to the below.At this moment, nozzle 5 also moves downwards.
Under this state, as shown in Figure 9, hook 4 extends to the radial direction inboard of stator core 3 once more.At this moment, hook 4 as shown in figure 10, by the bottom of coil-end 2, its front end enters the inboard of stator core 3, the line 9 that tractive is supplied with by nozzle 5.
Then, as shown in figure 11, hook 4 its front end drag wires 9 retreat by circle R2 to the radial direction outside of stator core 3.Form circle R3 on online thus 9.
Thereafter, as shown in figure 12, hook 4 is moved upward by the outside of coil-end 2 under the state of front end drag wire 9.Thus, will enclose R3 and pull to the top.At this moment, nozzle 5 also is moved upward.
In addition, make this moment stator core 3 (stator 1) only rotate the angle of regulation.The rotation of this stator core 3 is undertaken by indexing mechanism as shown in figure 13.This indexing mechanism is made of the pallet P and the motor M that keep stator core 3.At the periphery formative gear G of pallet P, the gear MG of this gear G and motor M side engagement.Thus, if motor M is rotated, indexing mechanism then can make stator core 3 related pallet P together rotate.
After making stator core 3 rotations, as shown in figure 14, hook 4 extends to the radial direction inboard of stator core 3 again.Repeat Fig. 6～shown in Figure 14 operation thereafter.Wherein, beginning suture 9s sews up in the coil-end 2 when carrying out above-mentioned tightening as shown in figure 15 together.Integral body with coil-end 2 is seamed into mesh-shape with line 9 at last.Finish like this and tighten operation.
Then, the treatment process with reference to Figure 16～Figure 18 opposite joint tie lines describes.After using line 9 to finish integral body with coil-end 2 to be seamed into mesh-shape, as shown in figure 16, cut off the line of supplying with from nozzle 9.Seam tie lines 9e as shown in figure 17, by last circle Rn with and previous circle Rn-1 pull out.The seam tie lines 9e that is drawn out is controlled by clamp etc. and to the peripheral direction tension of stator 1, carries out simple and easy knotting as shown in figure 18.Finish the treatment process of seam tie lines like this.The processing because such opposite joint tie lines 9e simply ties a knot can not form toe-in in knotting place.
Here, though be simple and easy toe-in, only otherwise coil-end 2 is applied the effect of power, toe-in just can not untied, but may act on coil-end 2 effectively when constituting motor etc., thereby only with the not talkative coil-end 2 of having fixed fully of this state.Just simple and easy toe-in may be untied.
Therefore, for the simple and easy toe-in that stitches tie lines 9e can not untied, in the fixing method of coil end of the stator of present embodiment, carry out japanning at seam tie lines 9e under by the state of simple and easy knotting and handle.With reference to Figure 19 this japanning processing is described.This japanning is handled and is carried out under high temperature (about 150 ℃).
The stator 3 that at first will be heated to predetermined temperature is installed on the work rotation axis 25.By making not shown motor driven, rotation axis 25 is rotated along arrow 26 directions.At this moment, from upside drip nozzle 21,22 and downside drip nozzle 23,24 to 2 lacquers of coil-end.Its result falls on the coil-end 2 from the lacquer that each mouth 21～24 drips, and covers the surface of each coiling, and owing to capillarity enters between each coiling, soaks to be contained in wherein.At this moment, follow the rotation of work rotation axis 25 and rotate owing to stator 1, the part that the lacquer that drips is fallen often changes, and lacquer soaks too and is contained in coil-end 2.
, with finish stator 1 that the soaking of lacquer contain from work rotation axis 25 take off, in drying oven, stator 1 is carried out dry through and handle thereafter.Make thus and soak the lacquer sclerosis that is contained in coil-end 2.Because the sclerosis of this lacquer, the also reinforcing of simple and easy knotting part of seam tie lines 9e, thereby can prevent that simple and easy toe-in from untiing.
Like this, in the fixing method of coil end of the stator of present embodiment,, also implement japanning and handle, therefore can firmly fix coil-end 2 owing to after not forming toe-in in coil-end 2 and tightening to stator 1.On the coil-end 2 of the stator 1 of implementing this fixing method of coil end, there is not toe-in.Therefore by using stator 1 to constitute motor, even be required miniaturization at motor, the gap of itself and housing has only the interference that also can not produce under the situation of several mm with housing.
As detailed above, in the fixing method of coil end of the stator of present embodiment, by the mutual action of nozzle 5 and hook 4 coil-end 2 of stator 1 is tightened, the suture 9s that will begin sews up coil-end 2.By making seam tie lines 9e by at the circle Rn of the last formation of tightening and the circle Rn-1 of its previous formation, tension and carry out simple and easy knotting, opposite joint tie lines 9e handles.Therefore, knotting place behind the seam knot can not form toe-in.Thereafter, carrying out japanning under the state of the simple and easy knotting of seam tie lines 9e handles.Thus, because the part of simple and easy knotting obtains reinforcing, can prevent that simple and easy toe-in from untiing.Just according to the fixing method of coil end of this stator, owing to after not forming toe-in the coil-end 2 of stator 1 being tightened, implement japanning again and handle, thereby can firmly fix coil-end 2.
Above execution mode is an illustration, and does not limit the present invention, as long as certainly carry out all distortion in the scope that does not break away from purport.For example automatically stitch the simple and easy knotting of tie lines 9e in the above-described embodiment, can certainly carry out simple and easy knotting by handwork.If but carry out simple and easy knotting then the productivity reduction by handwork.
