Abstract:
1. An articulating head with a linear movement assembly, adapted to be used with a CNC machine to work on a work piece, comprising: a pivot plate adapted to be attached and fixed to the CNC machine, said pivot plate attached to the CNC machine such that said pivot plate is movable back and forth on and by the CNC machine in one direction which is a movement in one directional plane, said pivot plate including a first connection point; a pivot arm rotatably attached to said pivot plate at a pivot arm rotation point on said pivot plate such that rotation of said pivot arm is in a second directional plane parallel to said one directional plane of movement of said pivot plate, said pivot arm having a second connection point, and said pivot arm adapted to allow mounting of a tool to work on the work piece; and a linear movement assembly mounted to and between said first connection point of said pivot plate and said second connection point of said pivot arm to cause rotation of said pivot arm about said pivot plate, said linear movement assembly comprising a threaded rod mounted as a screw, a nut which threads onto said screw and a motor interconnected to one of said screw and nut to cause motion between said screw and said nut, said screw and said nut being mounted between said pivot plate and said pivot arm, whereby said motion induced between said screw and nut causes said pivot arm to rotate about said pivot plate; wherein said screw is attached to a screw mount, said screw mount is rotatably attached to one of said first connection point and second connection point such that said screw mount rotates in a directional plane parallel to said one directional plane of movement of said pivot plate.
