Automated drilling station

An automated drilling station for use in a computer controlled manufacturing system, said drilling station comprising:

• means adjustably defining a planar work position having a central reference point for releasably clamping a planar work piece in said work position;
• a chuck assembly adapted to operatively receive a selected drill bit;
• means for selectively moving said chuck assembly on an axis perpendicular to the plane of said work position;
• means for storing a plurality of drill bits of various predetermined sizes;
• means operable independently of said chuck assembly for transferring said selected drill bit between said storing means and said chuck assembly at a transfer station remote from said work position;
• means for selectively translating said chuck assembly between said transfer station and said work position and between locations on one side of said work piece aligned with predetermined drilling locations in said work position;
• and
• means for selectively disposing a bushing having a size corresponding to said selected drill bit on the other side of said work piece aligned with said predetermined drilling drill locations in opposed relation to said chuck assembly.
