ABSTRACT:
A tool transfer arm is pivotally mounted on a tool transfer housing which is movable between a tool storage magazine and the spindle of a machine tool to transfer tools between the tool storage magazine and the spindle. The tool transfer arm has two pair of toolholder jaws, one pair on each end thereof. One toolholder jaw of each pair is movable and the other jaw is fixed. Each movable jaw is pivotable between an open and closed position by a clamp arm which is pivotally connected to the corresponding movable jaw and slidably engages an arcuate guide slot in the tool transfer arm. A cylindrical abutment on the spindle head near the spindle and on the tool storage magazine bears against the adjacent clamp arm when the tool transfer arm approaches either the tool storage magazine or the spindle in one angular orientation to close the corresponding movable jaw and clamp a toolholder in the jaws for removal from the tool storage magazine or spindle. A conical abutment on the spindle head near the spindle and on the tool storage magazine bears against the adjacent clamp arm when the tool transfer arm approaches either the tool storage magazine or the spindle in the other angular orientation to open the corresponding movable jaw and release the toolholder clamped in the jaws for insertion into the tool storage magazine or spindle.
