ABSTRACT:
A quick setting and release machine tool post having a body block structure forming a pair or partial dove tail tool mounts externally thereof. The body block also forms a pair of expander receptacles each receiving a dove tail expander element in movable assembly therewith. A rotary actuator located within an actuator receptacle defined by the body block forms oppositely directed intersecting eccentric cam surfaces that are disposed for driving engagement with respective dove tail expander elements depending upon the direction of rotation of the actuator element. The dove tail expander elements are selectively linearly movable to establish tight locking engagement within the dove tail receptacles of tool holders and are retractable to release the tool holders for replacement or repositioning. The design and operational characteristics of the tool post mechanism minimizes wear of component parts and promotes long service life.
