ABSTRACT:
A quick-change chuck device has a body member having an internal recess defined therein. An inner sleeve member is fitted into this recess and is axially movable relative to the body member. The inner sleeve has an internal bore defined therethrough which is concentric with the recess. An axial spring mechanism biases the inner sleeve member axially away from the body member. An axial movement locking device is configured with the inner sleeve member to allow a tool shank to slide into the internal bore of the inner sleeve when the sleeve is moved axially towards the body member and to axially lock the tool shank within the internal bore when the inner sleeve member is biased by the spring mechanism away from the body member. A rotational movement locking device is configured within the recess of the body member. The rotational movement locking device defines a bore aligned with the internal bore of the inner sleeve member for receiving the tool shank passing through the inner sleeve member. The rotational movement locking device comprises a plurality of spring loaded longitudinal bearing members disposed about the bore and extending radially into the bore. In this manner, the bearing members contact the tool shank. The bearing members are spring loaded tangentially inward so as to rotationally lock the tool shank against rotation in at least one rotational direction.
