Abstract
A tool mechanism for machining a hole side surface, and for chamfering the ends of the hole, includes a boring cutter and two chamfer cutters oriented so that during an axial infeed of the cutter assembly the hole side surface is machined and a chamfer is formed at one end of the hole. The cutter assembly can be shifted transversely to position a chamfer cutter for machining a second chamfer on the other end of the hole. The cutter assembly is carried on a cutter support member that is swingably mounted on a tool body secured to the spindle of the cutting machine. An actuator device is movable along the tool body axis to adjust the position of the cutter support member.
Claims17
A mechanism for finishing a circular hole in a workpiece in a chamfer at each end of the hole;
- said mechanism having a longitudinal operating axis;
- a cutter support member swivably mounted on said tool body for pivotable motion around a second axis that intersects said longitudinal axis, said axis being transverse to said longitudinal axis;
- an actuator slidably mounted on said tool body for axial motion along the tool body longitudinal axis;
- and a cam connection comprising a slider element pivotally connected to said actuator for swinging motion around a third axis that is parallel to said second axis, said cam connection between said actuator and said cutter support member, said cutter support member having a mating slideway member;
- said slideway member being acutely angled to the movement axis of the actuator;
- said slider element being slidably engaged with the slideway whereby motion of the actuator along the tool body longitudinal axis causes the cutter support member to be pivotally adjusted around said second axis, whereby axial motion of the actuator is translated into pivotable motion of the cutter support member.
