ABSTRACT:
Apparatus for providing a movable upright registration pin extending above a horizontal work surface for locating workpieces on the tooling plate of a computer controlled drilling machine. A straight edge member, disposed in a channel in the surface of the tooling plate, provides two vertical reference surfaces which are precisely located to define a line of position for the registration pin. The registration pin is maintained upright in a carrier that is slidably disposed in a channel in the straight edge member between the two reference surfaces. The rotation of a cam bar disposed adjacent the carrier applies force to the carrier which causes the registration pin to bear against the two vertical reference surfaces to precisely and securely locate the pin on the line of position. The registration pin may be pushed by the spindle of the drilling machine along the line of position and then locked in the registration position under the automatic control of the drilling machine. In a first embodiment, the height of the registration pin is fixed with respect to the surface of the tooling plate of the drilling machine. In a second embodiment, the spindle of the drilling machine may be used to automatically adjust the height of the registration pin above the tooling plate.
