At first, stator core 14 is placed in the layout mechanism 16.This stator core 14 comprises a lamination steel plate, and it is to be made by the multi-layered magnetic steel plate that is bonded together with adhesive or analog.Stator core 14 is placed with position, certain angle by layout mechanism 16.Then, drive the tube 36 that forms tooth detent mechanism 18, make backstay 38 to stator core 14 displacements.Conical surface 38a at front end is inserted between the adjacent tooth 12, thereby makes these teeth 12 fixing on the throne.
With respect to backstay 38 tooth keeper 40 is set.Tube 146 makes hook tube 144 move along direction shown in the arrow B 1.Therefore, carrying cylinder 86 moves along direction shown in the arrow B 1 by connecting pin 149.The elastic force of spring 90 makes certain tooth 12 butts of tooth keeper 40 and stator core 14, makes tooth 12 in place.
In side former 182, the location of side guide piece 192a and 192b make its opening for example above four teeth 12 to the outer surface (seeing Fig. 5 A) of stator core 14.The left guider 92 and right guider 94 footpaths that constitute wing former 22 are inwardly moved, and contact with stator core 14.
More particularly, if it is moving by the district to constitute the primary importance change motor 108 of left guider position regulator 104, if and second ball-screw 110 that is connected in driving shaft 108a rotates in a certain direction, so, the nut portion 114 with 110 engagements of second ball-screw makes first moving body 112 move along direction shown in the arrow B 1.First urceolus 118 and second urceolus 120 are installed on first moving body 112 by bearing 116.Urceolus 118 and 120 moves along direction shown in the arrow B 1 in rotary cylinder 60.
In right guider position regulator 106, according to the mode identical with left guider position regulator 104, the second place changes motor 126 and drives second moving body 130 by second ball-screw 128 along direction shown in the arrow B 1.First inner core 136 and second inner core 138 that are contained on second moving body 130 move along direction shown in the arrow B 1.Second push boat 142 that is contained on second inner core, 138 front ends by second mounting panel 140 promotes right guider 94 along direction shown in the arrow D1, and right guider is entered in the space that forms between certain tooth 12.
In this state, drive second motor 54 that constitutes second driving mechanism 30.The belt pulley 56 that is securely fixed on the motor driving shaft 54a makes rotary cylinder 60 rotate together with first urceolus 118 and first inner core 136 by the timing belt 58 that is enclosed within on belt pulley 56 and the belt pulley part 62.Winding nozzle 19 is installed on the rotary cylinder 60, and beginning is rotated with rotary cylinder 60.Enamelled wire L is wrapped on 4 teeth in the tooth of stator core 14, simultaneously by side guide piece 192a and 192b guiding, thereby forms the first coil 20a (seeing Fig. 5 A).
Shown in Fig. 5 B, winding nozzle 19 designs to such an extent that enamelled wire L is placed on constitute on the left guider 92 and right guider 94 of wing former 22, and is wrapped on the zone, and the zone that the tooth 12 by some is covered is wider than in this zone.Winding nozzle 19 is driven along direction shown in the arrow B by first motor 42 that constitutes first driving mechanism 28 together with slide 48, and slide 48 has the nut portion 50 with 44 engagements of first ball-screw, thereby forms the first coil 20a.
Form after the first coil 20a in the wide scope in space on four teeth 12 of a ratio, left guider position regulator 104 and right guider position regulator 106 are along being driven in the opposite direction with above-mentioned side.Therefore, first push boat 124 and second push boat 142 move along direction shown in the arrow B 2.Spring 96 and 100 elastic force make left guider 92 and right guider 94 move along direction shown in arrow C 2 and the D2 respectively.Therefore, guider 92 and 94 shifts out the rotary motion trace of tooth 12.
The tube 36 that comprises tooth detent mechanism 18 is driven.Backstay 38 moves backward, and the conical surface 38a on the front end is removed from 12 in tooth.On the other hand, tube 146 makes the hook tube move along direction shown in the arrow B 2.Therefore, carrying cylinder is along direction displacement shown in the arrow B 2, thereby tooth detent mechanism 40 is removed from tooth 12.
In this state, layout mechanism 16 makes stator core 14 turn over certain angle along direction shown in the arrow A.This angle equals the angle between the two adjacent teeth 12.Tooth detent mechanism 18 is provided with stator core 14 and be fixed on certain position.And then drive left guider position regulator 104 and right guider position regulator 106.Left side guider 92 and right guider 94 enter the space that forms between the adjacent teeth 12.
Then, drive second driving mechanism 30 to rotate winding nozzle 19.First driving mechanism 28 makes winding nozzle 19 swing along direction shown in the arrow B.The second coil 20b forms on a position in the stator core 14, this position along shown in the arrow G circumferentially from the first coil 20a move past one equal a tooth pitch apart from (see figure 6).At least a portion of the second coil 20b goes up the overlapping first coil 20a in radially (by the arrow H indication) of stator core 14.The second coil 20b is lap wound on four teeth 12, and this scope is wider than the scope that is covered by certain tooth 12, and its mode is identical with the first coil 20a.
Similar to first embodiment, on the scope of the scope that a tooth 12 of being wider than by some is covered, form the 4th coil 20d, its overlapping first coil 20a that makes progress in the footpath of stator core 14 at least in part.Then, form the 5th coil in the scope of the scope that a tooth 12 that equals substantially by some is covered, it does not cover the first coil 20a diametrically.
Specifically, shown in Fig. 7 A, left guider 92 and right guider 94 are spaced apart from the bottom surface of stator core 14.Second driving mechanism 30 rotates winding nozzle 19, forms the 5th coil 20e on four teeth 12.For this reason, the 5th coil 20e is wrapped on the scope of the scope that a tooth 12 that equals substantially by some covered.That is to say that coil 20e is wrapped in tightly on certain tooth 12 and (sees Fig. 7 B).
The 6th coil 20f and later coil equal according to each comfortable one of the mode identical with the 5th coil 20e to form on the scope of the scope that the tooth 12 by some covered substantially.When (N-2) individual coil 20
N-2When radially twining overlappingly with the first coil 20a, its scope is wider than a tooth pitch of tooth 12, thereby left guider 92 and right guider 94 are wrapped in coil 20
N-2In.Then, (N-1) individual coil and last N coil 20n according to (N-2) individual coil 20
N-2Identical mode is twined (see figure 8).
Then, as shown in Figure 3, comprise that first swing tube 172 of left thrust unit 162 and right thrust unit 164 and second swing tube 180 are driven.First promotes tube 168 and second promotes tube 176 and puts to position shown in the dotted line from retracted position shown in the solid line.
Now, first promotes the tube 168 and second promotion tube 176 is driven, and first impeller 170 and second impeller 178 are advanced.Left side insertion member 150 and right insertion member 152 are pushed along direction shown in arrow E 1 and the F1 respectively.As shown in Figure 9, left insertion member 150 and right insertion member 152 are revolted spring 154 and 156 respectively along direction shown in arrow E 1 and the F1 respectively and are moved.This just pushes N coil 20n to stator core 14, thereby forms winding at last.
In first embodiment, the first line chart 20a and with the first coil 20a along other coil 20b radially overlapping shown in the arrow H, 20c, 20d, 20
N-1, 20
N-2With 20

nAfter being wound, when N coil 20
nWhen pushing mechanism 24 and push stator core 14 central to, can guarantee that the first coil 20a and other coil 20 grades are by easily towards the distortion of stator core 14 central authorities by coil.Owing to have the gap between each first coil 20a and other coil 20 etc. and corresponding tooth 12, thereby the first coil 20a and other coil 20 etc. are with bigger degree of freedom distortion, so coil can be easily and distortion reliably.
So just improved the space factor of coil 20 grades in stator core 14 effectively.In addition, can prevent coil 20 grades and tooth 12 sliding contacts.Therefore, the insulating coating on enamelled wire L can be stripped from, well the insulation of hold-in winding 20 grades.
The method of using Wiring apparatus 10 winding arounds according to second embodiment of the invention is described below.Part identical in each accompanying drawing uses identical label, hereinafter repeats no more with the identical operations of using among first embodiment.
As shown in figure 10, constitute the left guider 92 of wing former 22 and right guider 94 stator core 14 radially to intrinsic displacement, enter the space between the two adjacent teeth 12 respectively.In this state, second motor 54 that constitutes second driving mechanism 30 is moved by the district so that begin the rotation of winding nozzle 19 together with rotary cylinder 60.Enamelled wire L twines on four teeth 12 in stator core 14 under the guiding of side guide piece 192a and 192b, thereby forms coil 20a.
At this moment, first motor 42 that constitutes first driving mechanism 28 drives winding nozzle together with slide 48 along direction shown in the arrow B 1, and slide 48 has the nut portion 50 with 44 engagements of first ball-screw, therefore forms the first coil 20a.
On four teeth 12, twine after the first coil 20a,, first push boat 124 and second push boat 142 are moved along direction shown in the arrow B 2 along driving left guider position regulator 104 and right guider position regulator 106 in the opposite direction with above-mentioned side.Spring 96 and 100 elastic force make left guider 92 and right guider 94 move along direction shown in arrow C 2 and the D2 respectively, make these guiders shift out the rotary motion trace of tooth 12.
In addition, the tube 36 of formation tooth detent mechanism 18 is driven so that bar 38 is return.This makes the conical surface 38a of front end remove from the space between the tooth 12.On the other hand, tube 146 makes hook tube 144 move along direction shown in the arrow B 2.Therefore, carrying cylinder moves along direction shown in the arrow B 2.This makes tooth keeper 40 leave tooth 12.
In this state, layout mechanism 16 makes stator core 14 turn over certain angle along direction shown in the arrow A.This angle equals the angle between the adjacent teeth 12.Tooth detent mechanism 18 is fixing on the throne with stator core, and coil pushes mechanism 24 and is driven then.
Specifically, as shown in Figure 3, first swing tube 172 and second swing tube 180 that constitute left thrust unit 162 and right thrust unit 164 respectively are driven.First promotes tube 168 and second promotes tube 176 and puts to position shown in the dotted line from position shown in its solid line.Then, first promotes the tube 168 and second promotion tube 176 is driven so that first impeller 170 and second impeller 178 are advanced, thereby left insertion member 150 and right insertion member 152 are moved along direction shown in arrow E 1 and the F1 respectively.
Therefore, left insertion member 150 and right insertion member 152 elastic force of revolting spring 154 and 156 respectively moves along direction shown in arrow E 1 and the F1 respectively.The first coil 20a is pushed to stator core 14 central authorities, thereby forms coil (seeing Figure 11) at last.
Be right after and promote and form after the first coil 20a, left guider position regulator 104 and right guider position regulator 106 are driven once more.Constitute wing 22 left guider 92 and the right guider 94 of growing up to be a useful person and enter the space that forms between the adjacent teeth 12.Second driving mechanism 30 is actuated to rotate winding nozzle 19.Winding nozzle was put first driving mechanism 28 along direction shown in the arrow B.
Therefore, second (next one) coil 20b is forming along the position of circumferentially moving a tooth pitch shown in the arrow G (Figure 12) from the first coil 20a in stator core 14.The second coil 20b is at least in part along radially (by arrow H indication) overlapping first coil 20a of stator core 14.
After layout mechanism 16 rotated an angle corresponding to the tooth pitch of tooth 12 along direction shown in the arrow A with stator core 14, coil pushed mechanism 24 and is driven.Therefore, the second coil 20b is pushed to stator core 14 central authorities according to the mode identical with the first coil 20a, is formed at last.Be right after and be formed up to the tertiary coil 20c of small part thereafter along the radially overlapping second coil 20b of stator core 14.
Similarly, form before the next coil 20, coil 20 all is pushed to stator core 14 central authorities at every turn, is formed at last, until forming last coil 20n.Make needed stator ST (seeing Figure 13) by this way.
In a second embodiment, in the formation that starts from the first coil 20a and terminate in the process of formation of last coil 20n, each coil 20 was tightly pushed mechanism 24 by coil and pushes the last coils that form of stator core 14 central authorities to before next coil 20 forms.Because each coil 20 is all pushed stator core 14 central authorities by this way to and is formed at last, thereby can realize highdensity lap wound.The space factor of lap wound is improved.
In addition, each coil 20 tightly was pushed to stator core 14 central authorities before next coil 20 is formed, and therefore can prevent that last coil 20 from rebounding.This space factor that further guarantees lap wound improves.
In Wiring apparatus 10, the wing former 22 that forms each coil 20 on four teeth 12 is provided with left guider 92 and right guider 94, and they can shift to and move apart stator core 14 by left guider position regulator 104 and right guider position regulator 106 respectively independently.Therefore, even the structure difference of lap wound also can be selected to constitute the drive controlling of the left guider 92 and the right guider 94 of wing former 22 simply, thereby easily solve the problem of remodeling, thereby easily obtain high-quality stator ST.
In this case, constituting coil pushes the left insertion member 150 of mechanism 24 and right insertion member 152 and advances by left thrust unit 162 and right thrust unit 164 respectively or retreat, push each coil 20 to stator core 14 central authorities, it is shaped, has therefore improved the space factor that is wrapped in the lap winding on the stator ST effectively.
Wing former 22 and coil push mechanism and are installed on the base plate 26.This base plate 26 can move perpendicular to stator core 14.This simplifies the structure significantly, thereby can easily realize high-quality lap wound.
Figure 14 is the cross-sectional plane graph of Wiring apparatus 200 that is used to implement the stator lap wound method of third embodiment of the invention.The part identical with the Wiring apparatus 10 of the winding method that is used to implement first and second embodiment uses identical label and will repeat no more.
Shown in Figure 15 and 16, coil recess builder 202 is provided with a left recess drip molding 204 and a right recess drip molding 206, and they can move forward and backward along direction shown in arrow E and the F by guide rail 158 and 160 respectively respectively by spring 154 and 156.Left side recess drip molding 204 and right recess drip molding 206 have crooked with mutual approaching fore-end 204a and 206a.Fore- end 204a and 206a can be inserted between the tooth 12 of stator core 14, thereby tooth 12 is arranged between the fore-end.
The operation of above-mentioned Wiring apparatus 200 will be described in conjunction with the winding method according to the 3rd embodiment.Under state shown in Figure 16, second motor 54 that constitutes second driving mechanism 30 is actuated to rotate winding nozzle 19 together with rotary cylinder 60.Therefore, enamelled wire L is wrapped on four teeth 12 in the stator core 14, forms the first coil 20a.Then, as shown in figure 16, constituting first swing tube 172 of left thrust unit 162 and right thrust unit 164 and second swing tube 180 respectively is driven so that make first to promote tube 168 and second and promote tube 176 and put to position shown in the dotted line by retracted position shown in the solid line from it.These two tubes 168 and 176 further are driven, so that first impeller 170 and second impeller 178 are advanced, promote left recess drip molding 204 and right recess drip molding 204 (Figure 15) along direction shown in arrow E 1 and the F1 respectively.
Therefore, left recess drip molding 204 and right recess drip molding 206 elastic force of revolting spring 154 and 156 respectively moves along direction shown in arrow E 1 and the F1.Recess forms between the fore-end 204a of part 204 and 206 and the tooth 12 that 206a is inserted in stator core 14 respectively, and each fore-end is between two adjacent teeth 12.Therefore, as shown in figure 17, two recess 210a and 210b are forming by promotion on corresponding to the position in the space between the tooth 12 on the first coil 20a.
After forming recess 210a and 210b,, the first promotion tube, the 168 and second promotion tube 176 by the elastic force of spring 154 and 156 left recess drip molding 204 and right recess drip molding 206 are return along the direction shown in arrow E 2 and the F2 respectively thereby being cut off energy.Constituting first swing tube 172 of left thrust unit 162 and right thrust unit 164 and second swing tube 180 moves respectively and promotes tube 176 and put to position shown in the solid line from position shown in the dotted line so that make first pendulum promote tube 168 and second.
On the other hand, left guider position regulator 104 and right guider position regulator 106 are along being driven in the opposite direction with above-mentioned side, and therefore, first push boat 124 and second push boat 142 move along direction shown in the arrow B 2.Spring 96 and 100 elastic force make left guider 92 and right guider 94 move along direction shown in arrow C 2 and the D2 respectively, thereby make two guiders shift out the rotary motion trace of tooth 12.
The tube 36 that constitutes tooth detent mechanism 18 is actuated to return backstay 38, makes front end conical surface 38a move apart space between the tooth 12.On the other hand, hook tube 144 by the action of tube 146 along moving by the direction shown in the arrow B 2.Therefore, carrying cylinder 86 moves along direction shown in the arrow B 2.Therefore, tooth keeper 40 is removed from tooth 12.
In this state, stator core 14 by layout mechanism 16 along the rotating certain angle of direction shown in the arrow A.This angle equals the angle between the adjacent tooth 12.Tooth detent mechanism 18 is provided with the also position of fixed stator iron core 14.Then, left guider position regulator 104 and right guider position regulator 106 are driven once more, make the left guider 92 that constitutes wing former 22 and right guider 94 advance to space between the tooth 12.Second driving mechanism 30 also is driven so that rotate winding nozzle 19.This nozzle 19 is swung along direction shown in the arrow B by first driving mechanism 28.Therefore, the second coil 20b is forming along the position that circumferentially moves past a tooth pitch of tooth 12 shown in the arrow G (Figure 18) from the first coil 20a in stator core 14.
In the 3rd embodiment, recess 210a and 210b are pushed operation and are formed on the first coil 20a.The fore-end of the second coil 20b is received among the recess 210a.Therefore, can finish highdensity lap wound.The space factor of lap winding can improve.When the pushing action of left recess drip molding 204 and right concave portion drip molding 206 formed recess 210a and 210b on coil 20, coil 20 was pushed to the central authorities of stator core 14.Therefore, the space factor that can guarantee lap winding improves.
Similarly, on each coil 20, form by the pushing action of left recess drip molding 204 and right recess drip molding 206 corresponding to two recess 210a in the space between the tooth 12 and 210b, until forming last coil 20n.The fore-end of next coil 20 is received among the recess 210a, therefore makes the stator ST (seeing Figure 19) that the high density lap wound has coil.
In the 3rd embodiment, each coil 20 is pushed, and forms two recess 210a and 210b on corresponding to the position in the space between the tooth 12.Therefore, when coil 20 is pushed, can prevent to float, therefore can realize the high density lap wound.If coil 20 can be pushed reliably, as long as form the front end of admitting coil 20.
As mentioned above, in according to lap winding of the present invention, first coil and other are wrapped in the scope along the overlapping coil of the stator core and first coil, and this scope is wider than the tooth pitch of winding tooth.After the winding around, can guarantee that coil is pushed, towards the distortion of stator core central authorities.Therefore, the space factor of lap winding can be improved, and can prevent that coil and toe joint from touching; As come in contact, insulating coating will be peeled off.The insulating properties of coil can keep satisfactorily.
In addition, in the present invention, coil is to twine on the tooth 12 of the stator core of some respectively.Each coil is pushed to the central authorities of stator core, tightly makes each coil forming before next coil twines.Therefore, can realize highdensity lap wound.The space factor of winding group can be improved.In addition, can make coil before next coil twines, prevent to rebound.
In addition, in the present invention, coil be tooth when stator core by the tooth detent mechanism fixedly the time, the line of being sent by wing former by winding nozzle forms.Wing position of growing up to be a useful person with respect to stator core is adjusted.Therefore, stagger-wound coil can be according to various winding condition easily, form in stator core reliably.Therefore, Wiring apparatus has extensive applicability in use.In addition, structure is also simplified, and can suppress the increase of production cost effectively.
In addition, in the present invention, after forming on the three or more teeth of coil in stator core, form one or more recesses on each coil, next coil is wrapped on three or four teeth, makes one of end face recess of coil, thereby forms lap winding.Therefore, an end of next coil is received within the recess of coil, thereby obtains highdensity lap winding.The lap winding space factor can be improved.In addition, be pushed part formation recess place coil at coil and be pushed to stator core central authorities.This space factor that can guarantee lap winding improves.
