Panel Locator Mechanism

       Disclosed is a mechanism that is used to accurately
locate a circuit board 9 while drilling in a drilling machine.  Three
of these mechanisms would be required to locate a panel in an X-Y
plane.

      Because of panel load/unload functions, the locators 1 have to
move in a vertical direction.  The motion is made through a
horizontal air driven slide 2, cam pin 3 and cam slot 4.  The slide
motion to the right places the lower surface of the angled cam slot 4
in contact with the cam pin 3.  The cam pin ends are engaged in holes
in the locators. The locators can move freely in the vertical
direction, sliding on the dowels 5.  Continued motion of the slide
places the locators in the upmost condition, as shown in view A-A.

      The upper straight part of the cam slot 7 functions as a
vertical dwell.  As the slide continues motion, the radiused edge 6
of the slide contacts the angled surfaces 8 of both locators, wedging
them apart in an equal and opposite manner.  One of the locators will
contact one of the panel locating notch edges.  That locator will
push the panel away from center until the other locator contacts the
other side of the locating notch edge.  The panel will come to rest
when an equal force has been applied to both locator notch edges by
each locator.
