STATOR MANUFACTURING APPARATUS OF ROTARY ELECTRIC MACHINE

PROBLEM TO BE SOLVED: To provide a stator manufacturing apparatus of a rotary electric machine, capable of twisting a plurality of coil conductors at the same time with a simple structure.SOLUTION: A stator manufacturing apparatus of a rotary electric machine, comprises: a peripheral direction rotation part 110 that can hold stator windings 102a to 102d in a ring state, and twists each stator winding while rotating in a peripheral direction; and a rotation driving part 120 that in a circular column, can be set to the peripheral direction rotation part 110 so that a long direction becomes vertical to an axial direction of the peripheral direction rotation part 110, and can rotate in its own peripheral direction. The peripheral direction rotation part 110 comprises twisted jigs 111a to 111d in a ring state and arranged in a concentric circular state. Each twisting jig comprises a groove part 112 that holds the stator winding, and can rotate in its own peripheral direction. When rotating, the rotation driving part 120, one end side in the long direction rotates the odd-numbered twisted jigs 111a and 111c toward an external side from an internal side of the peripheral direction rotation part 110, and the other end side in the long direction rotates the even-numbered twisted jigs 111b and 111d. The rotational direction of the odd-numbered twisting jigs and the rotational direction of the even-numbered twisting jigs are opposite to each other.SELECTED DRAWING: Figure 6 【課題】簡易な構造で複数のコイル導体を同時に捻ることができる、回転電機の固定子製造装置を提供する。【解決手段】リング状で固定子巻線１０２ａ〜１０２ｄを保持でき、周方向に回転して固定子巻線を捻る周方向回転部１１０と、円柱状で長さ方向が周方向回転部１１０の軸方向に垂直に周方向回転部１１０に設置でき、自らの周方向に回転できる回転駆動部１２０を備える。周方向回転部１１０は、リング状で同心円状に配置される捻り治具１１１ａ〜１１１ｄを備える。捻り治具は、固定子巻線を保持する溝部１１２を備え、自らの周方向に回転できる。回転駆動部１２０は、回転すると、長さ方向の一端側が、周方向回転部１１０の内側から外側に向かって奇数番目の捻り治具１１１ａ、１１１ｃを回転させ、長さ方向の他端側が、偶数番目の捻り治具１１１ｂ、１１１ｄを回転させ、奇数番目の捻り治具の回転方向と偶数番目の捻り治具の回転方向は、互いに逆である。【選択図】図６
