Abstract

PURPOSE: To simplify the construction of a power unit and facilitate its maintenance, by performing the quick feed, machining feed, quick return, etc. of a spindle by a mechanical and electrical mechanism.
CONSTITUTION: For the machining feed of a spindle 6, a clutch solenoid 27 of an electromagnetic brake clutch A is energized to attract the flange 25 of an hollow shaft 24 on a yoke 29. At that time, a reduction gear group B and gears 19, 20, 22 are rotated and the spindle 6 is fed forward at a reduced speed through a feed screw shaft 4 by the revolution speed difference between a feed screw cylinder 21 and the feed screw shaft 4. For the quick feed or return of the spindle, the clutch solenoid 27 of the electromagnetic brake clutch A is deenergized but its brake solenoid 26 is energized to attract the flange 25 thereon. At that time, the rotation of the gear group B and the gears 19, 20, 22 is stopped.
