The present invention pertains to a stator manufacturing method and a device therefor. All of segments are twisted in order to obtain a stator, the linear sections of the segments being inserted into slots in a stator core. The segments on the inner peripheral side are subsequently twisted after the segments on the outer peripheral side are untwisted. In order to achieve this, e.g., a fourth spindle that is positioned on the outermost peripheral side and is one of the first through fourth spindles for twisting the segments is disconnected from a fourth motor and brought to a non-rotatable state. The following is then performed in sequence: the third spindle is disconnected from a third motor and twisted, and the second spindle is disconnected from the second motor and twisted.

Stator manufacturing method and device therefor

A stator manufacturing apparatus is equipped with spindles as twisting and bending jigs, an inner guide having a first supply flow path and a suction flow path formed in the interior thereof, and an outer guide having a second supply flow path formed in the interior thereof. Further, the spindles have receiving members in which insertion recesses are formed. Through holes are formed in the receiving members, and the receiving members are formed with lateral holes therein which allow the interiors of the insertion recesses to communicate with each other.

Stator manufacturing method and apparatus

Two cylinder heads are disposed side by side. Upper side intake valve holes of one of the cylinder heads and upper side exhaust valve holes of the other of the cylinder heads are simultaneously machined by a multi-spindle head integrally including intake side tools and exhaust side tools. After moving the one of the cylinder heads upward by a pitch of the intake valves and moving the other of the cylinder heads upward by a pitch of the exhaust valves, remaining intake valve holes of the one of the cylinder heads and remaining exhaust valve holes of the other of the cylinder heads are simultaneously machined.

Machining method and machining apparatus of valve holes of cylinder head, and clamp device

Two cylinder heads () are disposed side by side. Upper side intake valve holes () of one of the cylinder heads () and upper side exhaust valve holes () of the other of the cylinder heads () are simultaneously machined by a multi-spindle head () integrally including intake side tools (to) and exhaust side tools (to). After moving the one of the cylinder heads () upward by a pitch Pof the intake valves and moving the other of the cylinder heads () upward by a pitch Pof the exhaust valves, remaining intake valve holes () of the one of the cylinder heads () and remaining exhaust valve holes () of the other of the cylinder heads () are simultaneously machined.
