Abstract
The present invention provides an improvement () in a Davenport® automatic screw machine having a stationary spindle. The improvement broadly includes a quick-change mechanism () associated with the stationary spindle (). The mechanism includes mating frusto-conical first and second surfaces () on the spindle and tool holder, and a multi-lead threaded connection () between the tool holder and stationary spindle such that the tool holder may be quickly locked into mating engagement with the stationary spindle by relative rotation therebetween through a short angular distance. The invention may also include an adjustment mechanism () that allows the axis (x—x) of the tool to be aligned with the axis (x—x) of a spaced rotatable spindle. This adjustment mechanism includes a base member (), an adjustment member (), and a locking mechanism () for selectively holding the adjustment member in the desired position relative to the base member.
