ABSTRACT:
A quick change adapter is provided for quickly changing a tool. The adapter includes a tubular-shaped inner member having an axial bore for receiving a shank of a tool, the inner member including a first portion and a second portion, the first portion having a diameter which is greater than a diameter of the second portion thereby defining a shoulder portion. The first portion includes at least one aperture extending between the outer surface and the axial bore. A ball is retained in the aperture and extends into the axial bore and beyond the outside surface of the inner member. The second portion of the inner member has an end which is adapted to be coupled to a tool chuck. A hollow tubular outer member is slidably mounted around the inner member and has a tapered inner wall therein and an end wall at one of its ends. A spring surrounds the second portion of the inner member and rests against the end wall at one end and rests against the shoulder portion at its other end. The spring biases the outer member in a direction which causes the tapered inner wall to forcibly engage the set of balls thereby forcing the balls inward towards the axial bore, thus clamping and retaining the shank of the tool axially and rotationally therein.
