Abstract
A clamping assembly for a tapered hollow shank of a rotary cutting tool provides for ease of access to a tapered recess of the adaptor. The clamping assembly is designed for retention on the tool shank so that the adaptor recess remains open for cleaning purposes. The clamping assembly is actuated through a simple axial arrangement so that a throughbore can be defined through it for receipt of a reamer or to define a central coolant passage if desired.
Claims6
A clamping assembly interposed between a hollow shank taper of a tool that rotates about an axis and an adaptor having a tapered recess that receives the tapered tool shank, the clamping assembly comprising:
- at least a pair of radially expandable projections adapted for receipt in an associated hollow shank of a tool;
- an actuator for selectively expanding and retracting the projections, the actuator including first and second members that move axially relative to one another so that in a first position of the members the projections are retracted, and in a second position of the members the projections are expanded to secure the clamping assembly to the tool shank whereby the tapered recess of the adaptor remains open for cleaning purposes;
- and
- a locking mechanism disposed in the adaptor for axially advancing the tapered tool shank into the tapered recess of the adaptor.
