Abstract
A collet chuck assembly for an axially fixed collet head. The collet head is fixedly and removably mounted in a threaded bushing to prevent axial motion, and is keyed into place to prevent rotation. A sleeve assembly has cam surfaces adapted to engage the cam surfaces of the collet head to open and close the collet head, and slides between collet head open and collet head closed positions within a spindle adapter body. The sleeve assembly has projections that extend from a rearward portion and pass through appropriately sized passages in the axially-fixed bushing. Motion from a spindle drawbar is transmitted by a drawbar link-up through the projections of the sleeve assembly. Using this arrangement, no physical connection is required between the drawbar link-up and the sleeve assembly. Additionally, no cap assembly is required.
