Abstract
A reconfigurable flying cutting, notching and shaping machine operates upon a workpiece traveling along a generally linear axis of motion. The machine supports one or more flying tools upon one or more splined shafts and provides bearings for travel along a splined shaft in a direction of movement parallel to the direction of work travel. Rotation of the splined shaft is coupled through a double-acting cam to move one or more flying cutting tools transversely to the splined shaft.
Claims15
A machine for cutting a workpiece traveling along an axis of motion, comprising:
- a ball spline shaft longitudinally extensive on an axis generally parallel to said workpiece axis of motion and rotatable about said longitudinally extensive axis;
- a cam longitudinally reciprocating relative to said ball spline shaft and coupled to rotate about said ball spline shaft longitudinally extensive axis upon rotation of said ball spline shaft;
- and
- a flying cutting tool operatively moved along said ball spline shaft at a rate coincident with the speed of a work piece passing through said machine, and coupled with said cam to actuate responsive to said cam rotation.
A flying notching and shearing machine for cutting a workpiece traveling along an axis of motion, comprising:
- a first ball spline shaft longitudinally extensive on an axis generally parallel to said workpiece axis of motion and rotatable about said longitudinally extensive axis;
- a first cam longitudinally reciprocating relative to said ball spline shaft and coupled through a ball spline bearing to rotate about said ball spline shaft longitudinally extensive axis upon rotation of said ball spline shaft, said first cam having a groove that varies in transverse displacement from said ball spline shaft at varying angular points about said ball spline shaft longitudinally extensive axis;
- a first arm coupled to a cam follower retained within said groove to provide displacing forces that alternatively move said arm transversely away from and towards said ball spline shaft;
- a first flying cutting tool operatively moved along said ball spline shaft at a rate coincident with the speed of a work piece passing through said machine, and coupled through said arm with said cam to actuate responsive to said cam rotation;
- a second ball spline shaft longitudinally extensive on an axis generally parallel to said workpiece axis of motion and rotatable about said longitudinally extensive axis;
- a second cam longitudinally reciprocating relative to said second ball spline shaft and coupled through a second ball spline bearing to rotate about said second ball spline shaft longitudinally extensive axis upon rotation of said second ball spline shaft, said second cam having a groove that varies in transverse displacement from said second ball spline shaft at varying angular points about said second ball spline shaft longitudinally extensive axis;
- a second arm coupled to a second cam follower retained within said second cam groove to provide displacing forces that alternatively move said second arm transversely away from and towards said second ball spline shaft;
- and
- a second flying cutting tool operatively moved along said second ball spline shaft at a rate coincident with said speed of said work piece passing through said machine, and coupled through said second arm with said second cam to actuate responsive to said second cam rotation.
