Description

ABSTRACT:
A device for positioning the tool head support plate of a machine tool crib in the required head change position, comprises a tool head support plate carried by a crib chain having rollers slidable along fixed guides. A swinging clamp contacts the plate and locks it along the direction of movement of the chain. A pull rod engages with a head on a pull stem on the plate and exerts a pulling action thereon to pull the rollers against the guides. A fluid pressure cylinder actuates a linkage that effects both of these movements.
