Abstract

PURPOSE: To make rough feed and minute feed possible, by constituting this device in such a manner that a nut and a worm wheel are moved in irrotational shapes by the revolution of a feed screw and the nut and the worm wheel are turned without rotating the feed screw by the revolution of a worm.
CONSTITUTION: A first driver turns only by pulse portions, the revolution is transmitted to a feed screw 16, and a nut 15 engaging with the feed screw 16 is connected to a worm 17 through a worm wheel 13 and moves in the axial direction in an irrotational shape to roughly feed a body W to be transported. The feed screw 16 is fixed by means of the first driver, pulses are added to turn a second driver only by pulse portions, the rotation is transmitted to the worm 17 and the nut 15 is turned through the worm wheel 13. Since the feed screw 16 does not turn, the nut 15 moves in the axial direction of the feed screw 16 to minutely feed the body W to be transported. Thus, the body can be fed roughly and minutely by means of a simple mechanism.
