Abstract
A motion conversion apparatus is disclosed having particular utility as a tool carrier actuator in a rotating taper thread generating tool head, wherein a plurality of tool carriers are moved axially of the workpiece and simultaneously transversly of the axis to form a tapered thread at the end of the workpiece. A portion of the actuating apparatus is mounted coaxially with a housing for the tool head and includes an inner and an outer actuating bar coupled together by helical keys and mating keyways such that relative axial motion between the inner and outer bars produces rotating movement of the outer bar. Rotation of the outer actuating bar is transferred to an actuating drum which has an outer surface having at least one helical keyway formed therein. In one embodiment, the actuating drum is a separate component rotating with the outer actuating bar via key-keyway pairs. A driven sleeve surrounds a portion of the actuating drum and is keyed to the helical keyway in a manner such that a given rotation of the drum produces a proportional axial linear movement by the sleeve.
