Abstract: This invention is related to a rigid tapping feedback assembly that is adapted to being retrofit on a milling machine having a spindle with a spindle end extending beyond a bearing cap and an automated drive. In embodiments, the assembly comprising a housing, spindle-pulley adapter that is drivably engaged with the spindle end, pulley assembly, shaft assembly, housing cover plate, and rotary encoder. The housing mounts to the bearing cap and holds the shaft assembly in substantially parallel-spaced alignment with the spindle-pulley adapter. The pulley assembly mechanically links the spindle-pulley adapter and the shaft assembly, typically utilizing pulleys and a timing belt. The housing cover plate mounts to the housing enclosing the assembly components above and supporting the rotary encoder in substantial axial alignment with the shaft assembly. In operation, the rotary encoder senses spindle rotational speed spindle and provides feedback to the automated drive to control downward movement of the spindle.

Abstract: An automated quill drive assembly is adapted to be retrofit on a milling machine having a frame presenting a quill head and a quill supported on the head for rotation and for relative shiftable movement along a linear axis between retracted and extended positions. The quill head includes a centrally disposed lower lug, a quill feed engagement control lever boss located above and spaced to one side of the lug, and a transmission cover opening located above and spaced to a side of the lug opposite the quill feed engagement control lever boss. The automated quill drive assembly includes a housing adapted to be mounted to the lug, the quill feed engagement control lever boss, and the transmission cover opening, a motor supported on the housing, and a transmission supported on the housing for transmitting automated movement from the motor to the quill to move the quill between the retracted and extended positions.
