As shown in FIGS. 5, 6, 7, and the like, the manufacturing apparatus 90 includes a core arranging portion 92 in which a plurality of divided cores 16 can be arranged in an annular shape, and a divided core arranged in the core arranging portion 92. It includes a leader wire support unit 94 that supports the coil leader wire 25 of 16, a processing device 96, a cutting device 98, and a position adjusting unit 100.

In the present embodiment, each divided core 16 is arranged in the core arranging portion 92 so that the leader wire accommodating portion 36 is located below the divided iron core 20. However, each divided core 16 may be arranged in the core arranging portion 92 in a state of being turned upside down.

引出線支持部９４は、コア配置部９２に配置された分割コア１６の第１コイル引出線２５ａが巻回される第１プーリ１０２と、当該分割コア１６の第２コイル引出線２５ｂが巻回される第２プーリ１０４とを有している。第１プーリ１０２及び第２プーリ１０４のそれぞれはＣ方向に沿って昇降可能に構成されている。 In the leader wire support portion 94, the first pulley 102 around which the first coil leader wire 25a of the division core 16 arranged in the core arrangement portion 92 is wound and the second coil leader wire 25b of the division core 16 are wound. It has a second pulley 104 to be formed. Each of the first pulley 102 and the second pulley 104 is configured to be able to move up and down along the C direction.

加工装置９６は、コア配置部９２に配置された分割コア１６に対してＡ方向に沿って移動可能に分割コア１６の外周側に配置された支持機構１１０と、支持機構１１０に設けられた第１加工部１１２及び第２加工部１１４とを有している。支持機構１１０は、第１加工部１１２及び第２加工部１１４をＣ方向に沿って昇降自在に支持している。 The processing apparatus 96 has a support mechanism 110 arranged on the outer peripheral side of the division core 16 so as to be movable along the A direction with respect to the division core 16 arranged in the core arrangement portion 92, and a first support mechanism 110 provided on the support mechanism 110. It has one processed portion 112 and a second processed portion 114. The support mechanism 110 supports the first processed portion 112 and the second processed portion 114 so as to be able to move up and down along the C direction.

図６に示すように、第１加工部１１２は、渡り線８２を形成するためのものであって、支持機構１１０に固定された第１駆動源１１６と、一方向に延在して第１駆動源１１６の作用下に変位（進退）するベース部１１８と、ベース部１１８に取り付けられたローラ支持部１２０と、ローラ支持部１２０に回転自在に支持された挿入ローラ部１２２とを備えている。 As shown in FIG. 6, the first processed portion 112 is for forming the crossover line 82, and extends in one direction to the first drive source 116 fixed to the support mechanism 110. It includes a base portion 118 that is displaced (advanced and retreated) under the action of the drive source 116, a roller support portion 120 attached to the base portion 118, and an insertion roller portion 122 that is rotatably supported by the roller support portion 120. ..

第１加工部１１２は、挿入ローラ部１２２の回転軸線Ａｘがステータコア１８の軸線方向（Ｃ方向）と略平行となるように配置されている。なお、第１加工部１１２は、任意の向きで（例えば、上下を反転させて）使用可能である。また、第１加工部１１２の構成において、第１駆動源１１６側を基端側と呼び、挿入ローラ部１２２側を先端側と呼ぶ。 The first processing portion 112 is arranged so that the rotation axis Ax of the insertion roller portion 122 is substantially parallel to the axis direction (C direction) of the stator core 18. The first processed portion 112 can be used in any direction (for example, turned upside down). Further, in the configuration of the first processing portion 112, the first drive source 116 side is referred to as a base end side, and the insertion roller portion 122 side is referred to as a tip end side.

本実施形態では、第１駆動源１１６は動力シリンダで構成されている。ただし、第１駆動源１１６は、動力シリンダに限らず、他の動力源、例えば電動モータであってもよい。ベース部１１８は、支持機構１１０に対してベース部１１８の延在方向に沿ってスライド可能に設けられている。ベース部１１８の基端側は第１駆動源１１６のロッド（出力軸）１１６ａに固定され、ベース部１１８の先端部は基端側よりも薄肉に形成されている。 In this embodiment, the first drive source 116 is composed of a power cylinder. However, the first drive source 116 is not limited to the power cylinder, and may be another power source, for example, an electric motor. The base portion 118 is slidably provided with respect to the support mechanism 110 along the extending direction of the base portion 118. The base end side of the base portion 118 is fixed to the rod (output shaft) 116a of the first drive source 116, and the tip end portion of the base portion 118 is formed to be thinner than the base end side.

ローラ支持部１２０は、ベース部１１８に取り付けられる支持部本体１２４と、支持部本体１２４の先端部に形成された貫通孔１２６に嵌入された円筒状のブッシュ１２８とを有している。支持部本体１２４は、ベース部１１８の延在方向に沿って延在している。 The roller support portion 120 has a support portion main body 124 attached to the base portion 118, and a cylindrical bush 128 fitted into a through hole 126 formed at the tip end portion of the support portion main body 124. The support portion main body 124 extends along the extending direction of the base portion 118.

挿入ローラ部１２２は、コイル引出線２５が収納溝５８、６０ａ、６０ｂ、６２ａ、６２ｂ、６４ａ、６４ｂに挿入されるようにコイル引出線２５に接触する外周面１３６ａを有する円板状のローラ本体１３６と、ローラ本体１３６の中央部に設けられてブッシュ１２８の内孔１３８に回転自在に挿入されたローラ軸１４０とを有している。 The insertion roller portion 122 is a disk-shaped roller body having an outer peripheral surface 136a that contacts the coil leader wire 25 so that the coil leader wire 25 is inserted into the storage grooves 58, 60a, 60b, 62a, 62b, 64a, 64b. It has 136 and a roller shaft 140 provided at the center of the roller main body 136 and rotatably inserted into the inner hole 138 of the bush 128.

ローラ本体１３６の厚みｄ２は各収納溝５８、６０ａ、６０ｂ、６２ａ、６２ｂ、６４ａ、６４ｂの溝幅よりも小さく形成されている。すなわち、ローラ本体１３６は収納溝５８、６０ａ、６０ｂ、６２ａ、６２ｂ、６４ａ、６４ｂ内に挿入可能となっている。これにより、挿入ローラ部１２２によりコイル引出線２５を収納溝５８、６０ａ、６０ｂ、６２ａ、６２ｂ、６４ａ、６４ｂ内に効率的に挿入することができる。 The thickness d2 of the roller body 136 is formed to be smaller than the groove widths of the storage grooves 58, 60a, 60b, 62a, 62b, 64a, and 64b. That is, the roller body 136 can be inserted into the storage grooves 58, 60a, 60b, 62a, 62b, 64a, 64b. As a result, the coil leader wire 25 can be efficiently inserted into the storage grooves 58, 60a, 60b, 62a, 62b, 64a, 64b by the insertion roller portion 122.

ローラ本体１３６の外周面１３６ａは、ローラ支持部１２０に回転自在に設けられた複数（図６の例では２つ）のバックアップローラ１４２の外周面に接触している。すなわち、各バックアップローラ１４２は、挿入ローラ部１２２（ローラ本体１３６）の回転に伴って回転する。 The outer peripheral surface 136a of the roller main body 136 is in contact with the outer peripheral surfaces of a plurality of (two in the example of FIG. 6) backup rollers 142 rotatably provided on the roller support portion 120. That is, each backup roller 142 rotates as the insertion roller portion 122 (roller body 136) rotates.

これにより、挿入ローラ部１２２を効率的に回転させながらコイル引出線２５からローラ本体１３６に作用する荷重をバックアップローラ１４２により受けることができる。よって、ローラ軸１４０によるブッシュ１２８の摩耗を効果的に低減することができるので、挿入ローラ部１２２を円滑に回転させることができる。なお、バックアップローラ１４２は１つ又は３つ以上であってもよい。 As a result, the backup roller 142 can receive the load acting on the roller body 136 from the coil leader wire 25 while efficiently rotating the insertion roller portion 122. Therefore, the wear of the bush 128 due to the roller shaft 140 can be effectively reduced, so that the insertion roller portion 122 can be smoothly rotated. The number of backup rollers 142 may be one or three or more.

図６に示すように、第２加工部１１４は、端子部８４を形成するためのものであって、第１加工部１１２によるコイル引出線２５の引き回し方向（図６の例ではＡ１方向）に第１加工部１１２に対して近接して配設されている。第２加工部１１４は、支持機構１１０に固定された第２駆動源１５６及びガイド部１５８と、第２駆動源１５６の作用下に進退する屈曲加工部１６０とを備えている。 As shown in FIG. 6, the second processed portion 114 is for forming the terminal portion 84, and is in the routing direction of the coil leader wire 25 by the first processed portion 112 (A1 direction in the example of FIG. 6). It is arranged close to the first processed portion 112. The second processed portion 114 includes a second drive source 156 and a guide portion 158 fixed to the support mechanism 110, and a bending processed portion 160 that moves forward and backward under the action of the second drive source 156.

本実施形態では、第２駆動源１５６はサーボモータで構成されている。ただし、第２駆動源１５６は、サーボモータに限らず、他の動力源、例えば、電動モータや動力シリンダであってもよい。第２駆動源１５６の出力軸１５６ａには、雄ねじが形成されている。 In this embodiment, the second drive source 156 is composed of a servomotor. However, the second drive source 156 is not limited to the servomotor, and may be another power source, for example, an electric motor or a power cylinder. A male screw is formed on the output shaft 156a of the second drive source 156.

ガイド部１５８は、Ｃ方向においてコイル引出線２５をローラ本体１３６の外周面１３６ａと略同じ位置に支持するものであって、ローラ本体１３６に対してＡ方向に近接して配設されている。ガイド部１５８は、Ｃ方向に沿って互いに対向する一対の板状の規制壁１６２、１６４を有している。各規制壁１６２、１６４は、一方向に（第１加工部１１２のベース部１１８の延在方向に沿って）延在しており、図示しない固定具によって互いに接続されている。 The guide portion 158 supports the coil leader wire 25 in the C direction at substantially the same position as the outer peripheral surface 136a of the roller main body 136, and is arranged close to the roller main body 136 in the A direction. The guide portion 158 has a pair of plate-shaped regulating walls 162 and 164 facing each other along the C direction. The regulatory walls 162 and 164 extend in one direction (along the extending direction of the base 118 of the first machined 112) and are connected to each other by fixtures (not shown).

屈曲加工部１６０は、各規制壁１６２、１６４の延在方向に沿って延在した板状部材であって、一対の規制壁１６２、１６４の隙間Ｓに屈曲加工部１６０の延在方向に沿って移動可能に配設されている。つまり、屈曲加工部１６０の厚みｄ３は、収納溝５８、６０ａ、６０ｂ、６２ａ、６２ｂ、６４ａ、６４ｂの溝幅Ｌ１よりも薄い。屈曲加工部１６０は、第２駆動源１５６の出力軸１５６ａの雄ねじに螺合する雌ねじが形成されたナット部１６８を含んでいる。これにより、屈曲加工部１６０は、第２駆動源１５６の作用下にその延在方向に沿ってガイド部１５８に対して進退可能となる。 The bending portion 160 is a plate-shaped member extending along the extending direction of each of the regulation walls 162 and 164, and is formed along the extending direction of the bending portion 160 in the gap S of the pair of regulation walls 162 and 164. It is arranged so that it can be moved. That is, the thickness d3 of the bent portion 160 is thinner than the groove width L1 of the storage grooves 58, 60a, 60b, 62a, 62b, 64a, 64b. The bending portion 160 includes a nut portion 168 in which a female screw to be screwed into the male screw of the output shaft 156a of the second drive source 156 is formed. As a result, the bending portion 160 can move forward and backward with respect to the guide portion 158 along the extending direction under the action of the second drive source 156.

屈曲加工部１６０のうちコイル引出線２５に接触する先端部（第２駆動源１５６が位置する側とは反対側の端部）には、ローラ本体１３６の外周面１３６ａの曲率よりも大きい曲率の湾曲面１６０ａが形成されている。 The tip of the bent portion 160 in contact with the coil leader wire 25 (the end opposite to the side where the second drive source 156 is located) has a curvature larger than the curvature of the outer peripheral surface 136a of the roller body 136. A curved surface 160a is formed.

図７に示すように、切断装置９８は、コア配置部９２に配置された分割コア１６に対して移動可能な切断装置本体１７０と、切断装置本体１７０に対してスライド自在に設けられてコイル引出線２５を切断する切断部１７２とを有している。切断装置本体１７０の下面には、位置調整部１００が回転自在に配設されている。 As shown in FIG. 7, the cutting device 98 is provided with a cutting device main body 170 that is movable with respect to the split core 16 arranged in the core arranging portion 92 and a coil drawing device that is slidably provided with respect to the cutting device main body 170. It has a cutting portion 172 for cutting the wire 25. A position adjusting portion 100 is rotatably arranged on the lower surface of the cutting device main body 170.

図８に示すように、コア配置部９２には、下方に延びると共にステータ１２の径方向に張り出す治具固定部９２ａが設けられている。治具固定部９２ａには、各端子部８４をばらけないように押える端子部保持治具２１０が各端子部８４に対応させて設けられている。 As shown in FIG. 8, the core arranging portion 92 is provided with a jig fixing portion 92a that extends downward and projects in the radial direction of the stator 12. The jig fixing portion 92a is provided with a terminal portion holding jig 210 that presses each terminal portion 84 so as not to come apart so as to correspond to each terminal portion 84.

図９に示すように、端子部保持治具２１０は、渡り線８２を引出線収納部３６（収納溝）内に押え付ける押え部材２２０と、進退機構２３０と、を備えている。 As shown in FIG. 9, the terminal portion holding jig 210 includes a pressing member 220 that presses the crossover wire 82 into the leader wire accommodating portion 36 (storage groove), and an advancing / retreating mechanism 230.

端子部保持治具２１０が治具固定部９２ａに固定されていることにより、押え部材２２０は、挿入ローラ部１２２に対してステータ１２の周方向（Ａ方向）に相対的に移動自在であり、挿入ローラ部１２２に対してステータ１２と一体に相対的に移動自在となっている。 Since the terminal portion holding jig 210 is fixed to the jig fixing portion 92a, the pressing member 220 is relatively movable in the circumferential direction (A direction) of the stator 12 with respect to the insertion roller portion 122. It is movable relative to the insertion roller portion 122 integrally with the stator 12.

進退機構２３０は、渡り線８２を押え付けた押圧状態（図９参照）と、挿入ローラ部１２２の移動経路外へ退避した退避状態（図１１参照）との間で進退自在に構成されている。進退機構２３０は、スライダ２４０と、スライダ２４０を昇降させる昇降装置２５０とを備えている。治具固定部９２ａには、径方向外側（Ｂ２方向）へ張り出させるように固定板２４２が固定されている。固定板２４２に、昇降装置２５０が固定されている。 The advancing / retreating mechanism 230 is configured to be freely advancing / retreating between a pressing state in which the crossover 82 is pressed (see FIG. 9) and a retracting state in which the insertion roller portion 122 is retracted out of the movement path (see FIG. 11). .. The advancing / retreating mechanism 230 includes a slider 240 and an elevating device 250 for raising / lowering the slider 240. A fixing plate 242 is fixed to the jig fixing portion 92a so as to project outward in the radial direction (B2 direction). The elevating device 250 is fixed to the fixing plate 242.

また、固定板２４２には、上方（Ｃ２方向）に向かって起立する背板２４４が設けられている。背板２４４の周方向一方側（Ａ２方向側）には、押え部材２２０、スライダ２４０の順に配置されており、押え部材２２０は、背板２４４とスライダ２４０により周方向（Ａ方向）から挟み込まれるように配置されている。 Further, the fixing plate 242 is provided with a back plate 244 that stands up upward (in the C2 direction). The presser member 220 and the slider 240 are arranged in this order on one side (A2 direction side) of the back plate 244 in the circumferential direction, and the presser member 220 is sandwiched by the back plate 244 and the slider 240 from the circumferential direction (A direction). It is arranged like this.

押え部材２２０のスライダ２４０に対向する面には、径方向外側（Ｂ２方向側）へ向かうに従って次第に上方（Ｃ１方向）へ傾斜するように延びるカム溝２２２が設けられている。 A cam groove 222 is provided on the surface of the pressing member 220 facing the slider 240 so as to gradually incline upward (C1 direction) toward the outer side in the radial direction (B2 direction side).

スライダ２４０の押え部材２２０に対向する面には、カム溝２２２に嵌合可能に配置された回転自在な複数のカムローラ２４１がカム溝２２２の傾斜方向に沿って設けられている。 On the surface of the slider 240 facing the pressing member 220, a plurality of rotatable cam rollers 241 arranged so as to be fitted in the cam groove 222 are provided along the inclination direction of the cam groove 222.

押え部材２２０とスライダ２４０とは、夫々の下端部分で周方向（Ａ方向）に重なり合っており、この重なり合う部分にコイルバネからなる付勢部材２４６が設けられている。付勢部材２４６は、スライダ２４０に対して押え部材２２０をカム溝２２２の傾斜方向に沿って上方へ押し上げるように押え部材２２０を付勢している。 The pressing member 220 and the slider 240 overlap each other in the circumferential direction (A direction) at the lower end portions thereof, and an urging member 246 made of a coil spring is provided at the overlapping portions. The urging member 246 urges the pressing member 220 so as to push the pressing member 220 upward along the inclination direction of the cam groove 222 with respect to the slider 240.

固定板２４２には、スライダ２４０の上下方向（Ｃ方向）の移動を案内するリニアガイド２４８が設けられている。スライダ２４０は昇降装置２５０の昇降ロッド２５２の先端に連結されている。スライダ２４０は、昇降装置２５０の昇降ロッド２５２の昇降運動によって、上下運動する。 The fixing plate 242 is provided with a linear guide 248 that guides the movement of the slider 240 in the vertical direction (C direction). The slider 240 is connected to the tip of the elevating rod 252 of the elevating device 250. The slider 240 moves up and down by the up and down movement of the elevating rod 252 of the elevating device 250.

背板２４４には、スライダ２４０の上昇に伴って上昇する押え部材２２０の上昇を所定位置で規制する規制部材２５４が設けられている。押え部材２２０には、渡り線８２を押え付ける爪部２２４が径方向内側（Ｂ１方向側）へ突出するように設けられている。押え部材２２０には、この爪部２２４の下方に位置させて、規制部材２５４に下方から当接可能に径方向内側（Ｂ１方向側）へ張り出す顎部２２６が設けられている。規制部材２５４は、爪部２２４が押え付ける予定の渡り線８２と同一の高さに位置したときに押え部材２２０のそれ以上の上昇を阻止するように背板２４４に取り付けられている。即ち、前記所定位置は、爪部２２４と押え付ける予定の渡り線８２が収容された引出線収納部３６の収納溝との高さが同一となる位置となる。 The back plate 244 is provided with a regulating member 254 that regulates the rise of the pressing member 220 that rises as the slider 240 rises at a predetermined position. The pressing member 220 is provided with a claw portion 224 for pressing the crossover wire 82 so as to project inward in the radial direction (B1 direction side). The pressing member 220 is provided with a jaw portion 226 located below the claw portion 224 and projecting inward in the radial direction (B1 direction side) so as to be in contact with the regulating member 254 from below. The regulating member 254 is attached to the back plate 244 so as to prevent the pressing member 220 from further rising when the claw portion 224 is located at the same height as the crossover line 82 to be pressed. That is, the predetermined position is a position where the heights of the claw portion 224 and the storage groove of the leader line accommodating portion 36 in which the crossover wire 82 to be pressed is accommodated are the same.

昇降装置２５０の昇降ロッド２５２を図１０に示す最下降の位置から上昇させると、図１１に示すように、前述した所定位置で規制部材２５４に押え部材２２０の顎部２２６が当接し、それ以上の押え部材２２０の上昇が阻止される。そして、更に昇降装置２５０でスライダ２４０が押し上げられると、図９に示すように、スライダ２４０は更に上昇する。これに対し、図９に示すように、押え部材２２０は、コイルバネからなる付勢部材２４６の不勢力に抗して、付勢部材２４６を押し縮めながら、カム溝２２２の傾斜方向に沿って径方向内側（Ｂ１方向）に移動する。 When the elevating rod 252 of the elevating device 250 is raised from the lowest position shown in FIG. 10, as shown in FIG. 11, the jaw portion 226 of the pressing member 220 abuts on the regulating member 254 at the predetermined position described above, and further. The rise of the holding member 220 is prevented. Then, when the slider 240 is further pushed up by the elevating device 250, the slider 240 is further raised as shown in FIG. On the other hand, as shown in FIG. 9, the pressing member 220 has a diameter along the inclination direction of the cam groove 222 while compressing the urging member 246 against the unforced force of the urging member 246 made of a coil spring. Move inward (B1 direction).

このとき、規制部材２５４によって押え部材２２０の径方向内側（Ｂ１方向）への移動が阻害されることの無いように、押え部材２２０には、顎部２２６に連続するようにして径方向外側（Ｂ２方向）に延びる逃げ部２２８が設けられている。そして、爪部２２４が渡り線８２を引出線収納部３６の収納溝内に押し付ける。 At this time, the pressing member 220 is connected to the jaw portion 226 so as to be continuous with the jaw portion 226 so as not to be hindered by the restricting member 254 from moving inward in the radial direction (B1 direction) of the pressing member 220. A relief portion 228 extending in the B2 direction) is provided. Then, the claw portion 224 presses the crossover wire 82 into the storage groove of the leader wire storage portion 36.

押え部材２２０による渡り線８２の押し付けを解除して退避位置に移動させるときには、反対に、図９、図１１、図１０の順に示すように、昇降装置２５０の昇降ロッド２５２を最上昇位置から下降させると、スライダ２４０が下降する。そして、スライダ２４０の下降に伴い、コイルバネからなる付勢部材２４６の付勢力によって、押え部材２２０が径方向外側（Ｂ２方向）に移動する。そして、押え部材２２０がスライダ２４０に対して付勢部材２４６の付勢力により径方向外側（Ｂ２方向）への移動が完了すると、規制部材２５４が逃げ部２２８から抜け出し、押え部材２２０がスライダ２４０と共に下方へ下降する。そして、押え部材２２０が挿入ローラ部１２２および屈曲加工部１６０と周方向（Ａ方向）において干渉しない位置まで下降させて退避位置までの移動が完了する。 When the crossover wire 82 is released from being pressed by the pressing member 220 and moved to the retracted position, on the contrary, as shown in the order of FIGS. 9, 11, and 10, the elevating rod 252 of the elevating device 250 is lowered from the highest ascending position. Then, the slider 240 is lowered. Then, as the slider 240 descends, the pressing member 220 moves radially outward (B2 direction) due to the urging force of the urging member 246 made of the coil spring. Then, when the pressing member 220 is completely moved outward (B2 direction) in the radial direction by the urging force of the urging member 246 with respect to the slider 240, the regulating member 254 comes out of the relief portion 228, and the pressing member 220 together with the slider 240. It descends downward. Then, the pressing member 220 is lowered to a position where it does not interfere with the insertion roller portion 122 and the bending processing portion 160 in the circumferential direction (A direction), and the movement to the retracted position is completed.

背板２４４の周方向他方側（Ａ１方向側）にも、同様に、押え部材２２０、スライダ２４０の順に配置されており、背板２４４は、夫々一対の押え部材２２０とスライダ２４０により周方向（Ａ方向）から挟み込まれるように配置されている。即ち、１つの端子部保持治具２１０には、周方向（Ａ方向）に一対の押え部材２２０及びスライダ２４０を備え、周方向に反転した点を除いて同一に構成され同一に作動する。そして、端子部８４は、背板２４４の図９における上方（Ｃ２方向）に位置することとなり、また、端子部８４は、背板２４４を挟むように配置された一対の押え部材２２０によって、端子部８４近傍の渡り線８２の部分が押さえ付けられることとなる。これにより、コイル２４から引き出されたコイル引出線２５を端子部８４まで周方向（Ａ方向）の一方（Ａ１方向）と他方（Ａ２方向）から分けて引出線収納部３６に巻き回した渡り線８２を適切に押えることができる。 Similarly, the pressing member 220 and the slider 240 are arranged in this order on the other side (A1 direction side) of the back plate 244 in the circumferential direction, and the back plate 244 is arranged in the circumferential direction by the pair of pressing members 220 and the slider 240, respectively. It is arranged so as to be sandwiched from (A direction). That is, one terminal holding jig 210 is provided with a pair of pressing members 220 and a slider 240 in the circumferential direction (A direction), and is configured and operates in the same manner except for a point inverted in the circumferential direction. The terminal portion 84 is located above the back plate 244 in FIG. 9 (C2 direction), and the terminal portion 84 is provided with terminals by a pair of pressing members 220 arranged so as to sandwich the back plate 244. The portion of the crossover line 82 in the vicinity of the portion 84 is pressed down. As a result, the coil leader wire 25 drawn from the coil 24 is separated from one (A1 direction) and the other (A2 direction) in the circumferential direction (A direction) to the terminal portion 84 and wound around the leader wire storage portion 36. 82 can be pressed appropriately.

本実施形態に係る回転電機１０の製造装置９０は以上のように構成されるものであって、次にこの製造装置９０を用いた回転電機１０の製造方法について説明する。 The manufacturing apparatus 90 of the rotary electric machine 10 according to the present embodiment is configured as described above, and next, a method of manufacturing the rotary electric machine 10 using the manufacturing apparatus 90 will be described.

まず、分割コア形成工程において、ステータコア１８を構成する全て（１８個）の分割コア１６を形成する。すなわち、分割鉄心２０を挟み込むように第１ボビン構成部３８を第２ボビン構成部４０に嵌合し、コイルボビン３４にワイヤを巻回してコイル２４を形成することにより分割コア１６を形成する。 First, in the split core forming step, all (18) split cores 16 constituting the stator core 18 are formed. That is, the split core 16 is formed by fitting the first bobbin component 38 into the second bobbin component 40 so as to sandwich the split iron core 20 and winding a wire around the coil bobbin 34 to form the coil 24.

次に、分割コア形成工程で形成された各分割コア１６について、分割コア配置工程、第１加工工程、及び第２加工工程を行う。 Next, for each of the divided cores 16 formed in the divided core forming step, a divided core arranging step, a first processing step, and a second processing step are performed.

分割コア配置工程では、図５に示すように、引出線収納部３６が分割鉄心２０の下方に位置するようにＵ１相の分割コア１６をコア配置部９２の所定箇所に配置して固定する。この場合、図６に示すように、１８個の分割コア１６が円環状に配置されることとなる。 In the split core arranging step, as shown in FIG. 5, the U1 phase split core 16 is arranged and fixed at a predetermined position in the core arranging portion 92 so that the leader wire accommodating portion 36 is located below the split iron core 20. In this case, as shown in FIG. 6, 18 divided cores 16 are arranged in an annular shape.

すなわち、Ｕ２〜Ｕ６相の第１コイル引出線２５ａが収納溝６２ａ、６２ｂ内に挿入されてＷ３相の分割コア１６の位置まで引き回されて渡り線８２ｕ及び端子部８４ｕが形成されている。Ｖ１〜Ｖ６相の第１コイル引出線２５ａが収納溝６０ａ、６０ｂ内に挿入されてＵ４相の分割コア１６の位置まで引き回されて渡り線８２ｖ及び端子部８４ｖが形成されている。 That is, the first coil leader wire 25a of the U2 to U6 phases is inserted into the storage grooves 62a and 62b and routed to the position of the split core 16 of the W3 phase to form the crossover wire 82u and the terminal portion 84u. The first coil leader wire 25a of the V1 to V6 phases is inserted into the accommodating grooves 60a and 60b and routed to the position of the split core 16 of the U4 phase to form the crossover wire 82v and the terminal portion 84v.

Ｗ１〜Ｗ６相の第１コイル引出線２５ａが収納溝５８内に挿入されてＶ４相の分割コア１６の位置まで引き回されて渡り線８２ｗ及び端子部８４ｗが形成されている。Ｕ１相以外の第２コイル引出線２５ｂが収納溝６４ａ、６４ｂ内に挿入されてＶ３相の分割コア１６の位置まで引き回されて渡り線８２ｎ及び端子部８４ｎが形成されている。 The first coil leader wire 25a of the W1 to W6 phases is inserted into the storage groove 58 and routed to the position of the split core 16 of the V4 phase to form the crossover wire 82w and the terminal portion 84w. The second coil leader wire 25b other than the U1 phase is inserted into the accommodating grooves 64a and 64b and routed to the position of the split core 16 of the V3 phase to form the crossover wire 82n and the terminal portion 84n.

分割コア配置工程では、Ｕ１相の第１コイル引出線２５ａを第１プーリ１０２に巻回し、Ｕ１相の第２コイル引出線２５ｂを第２プーリ１０４に巻回する。これにより、第１コイル引出線２５ａ及び第２コイル引出線２５ｂがステータコア１８の径方向外側に広がることを抑えることができる。つまり、製造装置９０の小型化を図ることができる。また、第１プーリ１０２をＣ方向に昇降させて収納溝６２ａ、６２ｂと略同じ位置にし、第２プーリ１０４をＣ方向に昇降させて収納溝６４ａ、６４ｂと略同じ位置にする。 In the split core arranging step, the U1 phase first coil leader wire 25a is wound around the first pulley 102, and the U1 phase second coil leader wire 25b is wound around the second pulley 104. As a result, it is possible to prevent the first coil leader wire 25a and the second coil leader wire 25b from spreading outward in the radial direction of the stator core 18. That is, the manufacturing apparatus 90 can be miniaturized. Further, the first pulley 102 is moved up and down in the C direction to be in substantially the same position as the storage grooves 62a and 62b, and the second pulley 104 is moved up and down in the C direction to be in substantially the same position as the storage grooves 64a and 64b.

第１加工工程では、Ｕ１相の第１コイル引出線２５ａについて、渡り線形成工程、端子部形成工程、位置調整工程、切断工程を順次行う。 In the first processing step, the crossover line forming step, the terminal portion forming step, the position adjusting step, and the cutting step are sequentially performed on the U1 phase first coil leader wire 25a.

渡り線形成工程では、第１加工部１１２のローラ本体１３６の外周面１３６ａ及び第２加工部１１４の一対の規制壁１６２、１６４の隙間ＳがＣ方向において収納溝６２ａ、６２ｂと略同じ位置になるように支持機構１１０を昇降させる。この際、ベース部１１８の先端部と支持部本体１２４の基端部の間に調整板１３２を介設することにより、Ｃ方向においてローラ本体１３６の外周面１３６ａを収納溝６２ａ、６２ｂと略同じ位置に精度よく位置決めすることができる。 In the crossover forming step, the gap S between the outer peripheral surface 136a of the roller body 136 of the first processing portion 112 and the pair of regulation walls 162 and 164 of the second processing portion 114 is located at substantially the same position as the storage grooves 62a and 62b in the C direction. The support mechanism 110 is moved up and down so as to be. At this time, by interposing the adjusting plate 132 between the tip end portion of the base portion 118 and the base end portion of the support portion main body 124, the outer peripheral surface 136a of the roller main body 136 is substantially the same as the storage grooves 62a and 62b in the C direction. It can be accurately positioned at the position.

また、図１２に示すように、加工装置９６が第１コイル引出線２５ａのＡ２方向の近傍に位置するように支持機構１１０を移動させる。このとき、挿入ローラ部１２２及び屈曲加工部１６０の進退方向は、ステータコア１８の径方向（Ｂ方向）に対して交差している。 Further, as shown in FIG. 12, the support mechanism 110 is moved so that the processing device 96 is located near the first coil leader line 25a in the A2 direction. At this time, the advancing / retreating directions of the insertion roller portion 122 and the bending portion 160 intersect with each other in the radial direction (B direction) of the stator core 18.

そして、第１コイル引出線２５ａを一対の規制壁１６２、１６４の隙間Ｓに挿通させると共にガイドローラ１６６の外周面に接触させる。なお、屈曲加工部１６０は退避状態にあるので、屈曲加工部１６０が第１コイル引出線２５ａに当たり損傷することを抑えることができる。 Then, the first coil leader wire 25a is inserted into the gap S of the pair of regulation walls 162 and 164 and brought into contact with the outer peripheral surface of the guide roller 166. Since the bending portion 160 is in the retracted state, it is possible to prevent the bending portion 160 from hitting the first coil leader wire 25a and being damaged.

続いて、図１３に示すように、コア配置部９２をＡ２方向に回転させる。このとき、加工装置９６の支持機構１１０についてもＡ方向に沿って移動させてもよい。そうすると、第１コイル引出線２５ａは、第１プーリ１０２から引き出されてガイドローラ１６６によって一対の規制壁１６２、１６４の隙間に案内され、これら規制壁１６２、１６４によって上下方向の移動が規制された状態でローラ本体１３６の外周面１３６ａに導かれ、ローラ本体１３６の外周面１３６ａに接触して収納溝６２ａ、６２ｂ内に挿入される（押し込まれる）。そして、コア配置部９２のＡ２方向の回転に伴って第１コイル引出線２５ａが収納溝６２ａ、６２ｂ内にＡ１方向に向かって引き回されることとなる。 Subsequently, as shown in FIG. 13, the core arranging portion 92 is rotated in the A2 direction. At this time, the support mechanism 110 of the processing apparatus 96 may also be moved along the A direction. Then, the first coil leader wire 25a is pulled out from the first pulley 102 and guided by the guide roller 166 into the gap between the pair of regulation walls 162 and 164, and the vertical movement is restricted by these regulation walls 162 and 164. In this state, it is guided to the outer peripheral surface 136a of the roller main body 136, comes into contact with the outer peripheral surface 136a of the roller main body 136, and is inserted (pushed) into the storage grooves 62a and 62b. Then, as the core arranging portion 92 rotates in the A2 direction, the first coil leader wire 25a is routed into the storage grooves 62a and 62b in the A1 direction.

このとき、挿入ローラ部１２２はローラ本体１３６の外周面１３６ａが第１コイル引出線２５ａの表面に接触することによりローラ支持部１２０に対して回転する。そのため、ローラ本体１３６の外周面１３６ａと第１コイル引出線２５ａの表面との間に生じる滑り摩擦を比較的小さくすることができる。 At this time, the insertion roller portion 122 rotates with respect to the roller support portion 120 when the outer peripheral surface 136a of the roller main body 136 comes into contact with the surface of the first coil leader wire 25a. Therefore, the sliding friction generated between the outer peripheral surface 136a of the roller main body 136 and the surface of the first coil leader wire 25a can be made relatively small.

また、第１コイル引出線２５ａからローラ本体１３６に作用する荷重をバックアップローラ１４２で受けるため、ローラ軸１４０の外周面とブッシュ１２８の内周面との間の摩擦を比較的小さくすることができる。これにより、挿入ローラ部１２２を効率的に回転させることができる。 Further, since the backup roller 142 receives the load acting on the roller body 136 from the first coil leader wire 25a, the friction between the outer peripheral surface of the roller shaft 140 and the inner peripheral surface of the bush 128 can be relatively reduced. .. As a result, the insertion roller portion 122 can be efficiently rotated.

Ｕ１相の第１コイル引出線２５ａを引き回す場合（本実施形態における第２挿入工程に相当する。この場合、）、既にＵ２相の第１コイル引出線２５ａとＵ３相の第１コイル引出線２５ａとがＡ１方向に沿ってＷ３相の分割コア１６の位置まで収納溝６２ａ、６２ｂ内に引き回されている。そのため、Ｕ１相の第１コイル引出線２５ａをＵ２相の第１コイル引出線２５ａよりもステータコア１８の径方向外方（Ｂ２方向）に引き回す際に、第１駆動源１１６の作用下に挿入ローラ部１２２を第１駆動源１１６側に若干後退させる。これにより、挿入ローラ部１２２の第１コイル引出線２５ａに対する押込み力が過度に大きくなることを抑制することができる。 When the first coil leader wire 25a of the U1 phase is routed (corresponding to the second insertion step in the present embodiment, in this case), the first coil leader wire 25a of the U2 phase and the first coil leader wire 25a of the U3 phase have already been routed. Is routed in the storage grooves 62a and 62b along the A1 direction to the position of the W3 phase split core 16. Therefore, when the first coil leader wire 25a of the U1 phase is routed radially outward (B2 direction) of the stator core 18 from the first coil leader wire 25a of the U2 phase, the insertion roller is under the action of the first drive source 116. The unit 122 is slightly retracted toward the first drive source 116. As a result, it is possible to prevent the pushing force of the insertion roller portion 122 with respect to the first coil leader wire 25a from becoming excessively large.

Ｕ１相の第１コイル引出線２５ａを第２渡り線として収納溝に引き回す場合を、本実施形態における第２挿入工程とする場合には、本実施形態の第１挿入工程は、既に引き回されているＵ２相の第１コイル引出線２５ａを第１渡り線として、Ａ１方向に沿ってＷ３相の分割コア１６の位置まで収納溝６２ａ、６２ｂ内に引き回す工程となる。即ち、本実施形態において、既に収納溝内に引き回された第１渡り線の挿入工程を第１挿入工程と規定し、収容溝内に引き回された渡り線に重なり合うように同一の収容溝に挿入して引き回す第２渡り線の挿入工程を第２挿入工程と規定する。 When the case where the first coil leader wire 25a of the U1 phase is routed to the storage groove as the second crossover is the second insertion step in the present embodiment, the first insertion step of the present embodiment has already been routed. The U2 phase first coil leader wire 25a is used as the first crossover wire, and is routed in the storage grooves 62a and 62b along the A1 direction to the position of the W3 phase dividing core 16. That is, in the present embodiment, the process of inserting the first crossover that has already been routed into the accommodating groove is defined as the first insertion step, and the same accommodating groove is overlapped with the crossover that has been routed into the accommodating groove. The process of inserting and routing the second crossover is defined as the second insertion process.

第１コイル引出線２５ａがＵ２の端子部８４ｕの近く（Ｗ３相の分割コア１６の位置）まで引き回されると、コア配置部９２の回転を停止させる。なお、加工装置９６の支持機構１１０をＡ方向に沿って移動させている場合にはその移動についても停止させる。このように、Ｕ１相の第１コイル引出線２５ａが収納溝６２ａ、６２ｂ内に挿入されてＷ３相の分割コア１６の位置まで引き回されることにより渡り線８２ｕが形成される。 When the first coil leader wire 25a is routed near the terminal portion 84u of U2 (the position of the split core 16 of the W3 phase), the rotation of the core arrangement portion 92 is stopped. When the support mechanism 110 of the processing device 96 is moved along the A direction, the movement is also stopped. In this way, the first coil leader wire 25a of the U1 phase is inserted into the accommodating grooves 62a and 62b and routed to the position of the split core 16 of the W3 phase to form the crossover wire 82u.

端子部形成工程及び位置調整工程では、図１４に示す押え部材２２０で押さえ付けた押圧状態から、図７および図１５の点線に示すように、押え部材２２０が退避状態に移行し、第２駆動源１５６の作用下に屈曲加工部１６０を進行させると共に位置調整ローラ１８０の支持凹部１８４を第１コイル引出線２５ａのうち渡り線８２ｕから延出する延出部１８８にＡ１方向から押し当てた状態で切断装置９８を第２加工部１１４が位置する側に移動させる。 In the terminal portion forming step and the position adjusting step, the holding member 220 shifts from the pressed state pressed by the pressing member 220 shown in FIG. 14 to the retracted state as shown by the dotted lines in FIGS. 7 and 15, and the second drive is performed. A state in which the bending portion 160 is advanced under the action of the source 156 and the support recess 184 of the position adjusting roller 180 is pressed against the extension portion 188 extending from the crossover line 82u of the first coil lead line 25a from the A1 direction. Moves the cutting device 98 to the side where the second processing portion 114 is located.

そうすると、屈曲加工部１６０の先端部の湾曲面１６０ａが第１コイル引出線２５ａのうち一対の規制壁１６２、１６４の隙間Ｓに位置する部位に接触し、屈曲加工部１６０に押された当該部位が屈曲加工され、収納溝６２ａ又は収納溝６２ｂ内に挿入されると共にＵ１相の端子部８４ｕが形成される。 Then, the curved surface 160a at the tip of the bending portion 160 comes into contact with the portion of the first coil leader wire 25a located in the gap S of the pair of regulation walls 162 and 164, and the portion is pushed by the bending portion 160. Is bent and inserted into the storage groove 62a or the storage groove 62b, and the U1 phase terminal portion 84u is formed.

その後、図１６に示すように、切断装置９８を第２加工部１１４から離間するように第１プーリ１０２が位置する側に移動させる。そうすると、Ｕ１相の端子部８４ｕ（延出部１８８）がスプリングバックする。そうすると、Ｕ１相の端子部８４ｕがＵ１相の渡り線８２ｕに対してＢ２方向に略９０度屈曲してＵ２相の端子部８４ｕに接触する。これにより、Ｕ１相の渡り線８２ｕに対するＵ１相の端子部８４ｕの屈曲角度を適切な角度に保持することができる。すなわち、Ｕ１相の端子部８４ｕを精度よく形成することができる。 After that, as shown in FIG. 16, the cutting device 98 is moved to the side where the first pulley 102 is located so as to be separated from the second processed portion 114. Then, the terminal portion 84u (extending portion 188) of the U1 phase springs back. Then, the U1 phase terminal portion 84u bends approximately 90 degrees in the B2 direction with respect to the U1 phase crossover 82u and comes into contact with the U2 phase terminal portion 84u. As a result, the bending angle of the terminal portion 84u of the U1 phase with respect to the crossover wire 82u of the U1 phase can be maintained at an appropriate angle. That is, the U1 phase terminal portion 84u can be formed with high accuracy.

切断工程では、図１７に示すように、切断装置９８の切断部１７２によって延出部１８８における端子部８４ｕとの境界部を切断するとともに、屈曲加工部１６０を後退させて、押え部材２２０を押圧状態に移行させて渡り線８２をしっかりと保持する。その後、図１８に示すように、挿入ローラ部１２２も径方向外側に退避させる。 In the cutting step, as shown in FIG. 17, the cutting portion 172 of the cutting device 98 cuts the boundary portion of the extending portion 188 with the terminal portion 84u, and the bending portion 160 is retracted to press the pressing member 220. It shifts to the state and holds the crossover line 82 firmly. After that, as shown in FIG. 18, the insertion roller portion 122 is also retracted to the outside in the radial direction.

第２加工工程では、Ｕ１相の第２コイル引出線２５ｂについて、渡り線形成工程、端子部形成工程、位置調整工程、切断工程を順次行う。すなわち、第２加工工程は、上述した第１加工工程と同様に行われるため、その詳細な説明を省略する。なお、本実施形態では、第１加工工程と第２加工工程を同時に行ってもよい。この場合、製造装置９０は、加工装置９６を２つ用意する必要がある。 In the second processing step, the crossover line forming step, the terminal portion forming step, the position adjusting step, and the cutting step are sequentially performed for the U1 phase second coil leader wire 25b. That is, since the second processing step is performed in the same manner as the first processing step described above, detailed description thereof will be omitted. In this embodiment, the first processing step and the second processing step may be performed at the same time. In this case, the manufacturing apparatus 90 needs to prepare two processing apparatus 96.

第２加工工程の完了により全ての分割コアについての作業が完了するので、各端子部８４ｕ、８４ｖ、８４ｗに圧着端子８５ｕ、８５ｖ、８５ｗを接合することにより各入力端子Ｕ、Ｖ、Ｗを形成し（図１参照）、今回の回転電機１０の製造方法が終了する。 Since the work for all the divided cores is completed by the completion of the second processing step, the input terminals U, V, W are formed by joining the crimp terminals 85u, 85v, 85w to the terminal portions 84u, 84v, 84w. (See FIG. 1), the manufacturing method of the rotary electric machine 10 this time is completed.

上記では、コイル引出線２５をＡ１方向に沿って引き回す例について説明したが、コイル引出線２５をＡ２方向に沿って引き回す場合は、加工装置９６の第１加工部１１２と第２加工部１１４の位置が入れ替えられる。すなわち、第１加工部１１２のＡ２方向に第２加工部１１４が位置することとなる。 In the above, an example in which the coil leader wire 25 is routed along the A1 direction has been described, but when the coil leader wire 25 is routed along the A2 direction, the first processing portion 112 and the second processing portion 114 of the processing apparatus 96 The positions are swapped. That is, the second processed portion 114 is located in the A2 direction of the first processed portion 112.

本実施形態によれば、渡り線８２を収容部としての引出線収納部３６に巻き回すときにも緩みなく重ね合わせながら渡り線８２を巻きまわすことができ、また、巻き回した後も渡り線８２の引出線収納部３６への巻き回しが緩むことがなく、渡り線８２の間の隙間を小さくすることができる回転電機１０のステータ製造治具としての端子部保持治具２１０を提供することができる。 According to the present embodiment, when the crossover wire 82 is wound around the leader wire accommodating portion 36 as the accommodating portion, the crossover wire 82 can be wound while being overlapped without loosening, and the crossover wire 82 can be wound even after being wound. Provided is a terminal portion holding jig 210 as a stator manufacturing jig of a rotary electric machine 10 capable of reducing a gap between crossover wires 82 without loosening the winding of 82 to a leader wire accommodating portion 36. Can be done.

また、押え部材２２０を、渡り線８２を押え付けた押圧状態と、屈曲加工部１６０の移動経路外へ退避した退避状態との間で進退自在な進退機構２３０（例えば、動力シリンダ、電動モータなどで構成することができる。）で進退させることができるため、屈曲加工部１６０による端子部８４の屈曲加工時に屈曲加工部１６０と押え部材２２０とが干渉することを防止することができる。 Further, the advancing / retreating mechanism 230 (for example, a power cylinder, an electric motor, etc.) that can advance / retreat freely between the pressing state in which the pressing member 220 presses the crossover line 82 and the retracted state in which the pressing member 220 is retracted out of the moving path of the bending processing portion 160 It is possible to prevent the bending portion 160 and the pressing member 220 from interfering with each other during the bending processing of the terminal portion 84 by the bending processing portion 160.

また、本実施形態によれば、渡り線８２を形成するための挿入ローラ部１２２と端子部８４を形成するための屈曲加工部１６０とを別々に設けているので、渡り線８２の表面の損傷を抑えつつ端子部８４を確実に形成することができる。また、挿入ローラ部１２２がローラ支持部１２０に対して回転自在に支持されているため、コイル引出線２５を収納溝５８、６０ａ、６０ｂ、６２ａ、６２ｂ、６４ａ、６４ｂ内に挿入する際に挿入ローラ部１２２のローラ本体１３６の外周面１３６ａとコイル引出線２５との間に生じる滑り摩擦を比較的小さくすることができる。これにより、渡り線８２の表面の損傷を一層抑えることができる。 Further, according to the present embodiment, since the insertion roller portion 122 for forming the crossover wire 82 and the bending processing portion 160 for forming the terminal portion 84 are separately provided, the surface of the crossover wire 82 is damaged. The terminal portion 84 can be reliably formed while suppressing the above. Further, since the insertion roller portion 122 is rotatably supported with respect to the roller support portion 120, the coil leader wire 25 is inserted when it is inserted into the storage grooves 58, 60a, 60b, 62a, 62b, 64a, 64b. The sliding friction generated between the outer peripheral surface 136a of the roller body 136 of the roller portion 122 and the coil leader wire 25 can be made relatively small. As a result, damage to the surface of the crossover line 82 can be further suppressed.

また、屈曲加工部１６０の湾曲面１６０ａの曲率がローラ本体１３６の外周面１３６ａの曲率よりも大きいため、渡り線８２の表面の損傷を効果的に抑えつつ端子部８４を一層確実に形成することができる。 Further, since the curvature of the curved surface 160a of the bending portion 160 is larger than the curvature of the outer peripheral surface 136a of the roller body 136, the terminal portion 84 can be formed more reliably while effectively suppressing damage to the surface of the crossover line 82. Can be done.

本実施形態では、コイル引出線２５の引き回し方向にローラ本体１３６に近接して配設されたガイド部１５８が、コイル引出線２５をローラ本体１３６の外周面１３６ａと略同じ位置に支持している。そのため渡り線形成工程の際に、コイル引出線２５がローラ本体１３６の外周面１３６ａから脱離することを抑えることができる。 In the present embodiment, the guide portion 158 arranged close to the roller main body 136 in the routing direction of the coil leader wire 25 supports the coil leader wire 25 at substantially the same position as the outer peripheral surface 136a of the roller main body 136. .. Therefore, it is possible to prevent the coil leader wire 25 from being detached from the outer peripheral surface 136a of the roller main body 136 during the crossover wire forming step.

また、一対の規制壁１６２、１６４の隙間Ｓに屈曲加工部１６０を設けているので、簡易な構成により、コイル引出線２５をローラ本体１３６の外周面１３６ａと略同じ位置に確実に支持することができる。 Further, since the bending portion 160 is provided in the gap S of the pair of regulation walls 162 and 164, the coil leader wire 25 can be reliably supported at substantially the same position as the outer peripheral surface 136a of the roller main body 136 by a simple configuration. Can be done.

本実施形態によれば、第１加工部１１２がウェーブワッシャ１５０、１５４（フローティング部）を有しているので、収納溝５８、６０ａ、６０ｂ、６２ａ、６２ｂ、６４ａ、６４ｂの溝側面に凸部６６ａ、６６ｂ、６８ａ、６８ｂ、７０ａ、７０ｂ、７２ａ、７２ｂが形成されている場合であっても、コイル引出線２５がローラ本体１３６の外周面１３６ａから脱離することを抑えることができる。 According to the present embodiment, since the first processed portion 112 has the wave washer 150, 154 (floating portion), the convex portion on the groove side surface of the storage grooves 58, 60a, 60b, 62a, 62b, 64a, 64b. Even when 66a, 66b, 68a, 68b, 70a, 70b, 72a, 72b are formed, it is possible to prevent the coil leader wire 25 from detaching from the outer peripheral surface 136a of the roller body 136.

また、位置調整部１００を切断装置９８に設けているので、回転電機１０の製造装置９０のコンパクト化を図りつつ、位置調整部１００によって位置決めされた延出部１８８を切断部１７２により容易に切断することができる。 Further, since the position adjusting unit 100 is provided in the cutting device 98, the extending portion 188 positioned by the position adjusting unit 100 can be easily cut by the cutting unit 172 while making the manufacturing apparatus 90 of the rotary electric machine 10 compact. can do.
