Abstract:
An automated quill drive assembly for use on a milling machine, wherein the milling machine includes a frame presenting a quill head, a quill supported on the head for rotation and for selective movement along a generally vertical axis between retracted and extended positions, and a manually actuated lever supported on the head and operatively connected to the quill for moving the quill between the retracted and extended positions, the automated quill drive assembly comprising:a housing; a motor supported on the housing; a transmission supported on the housing and being adapted for connection between the motor and the quill of the milling machine for transmitting automated movement from the motor to the quill to move the quill between the retracted and extended positions; and means for sensing the position of the quill as the quill is moved between the retracted and extended positions, the sensing means providing an output signal indicative of the position of the quill during both manual and automated movement.
