Abstract
A locking pin system for clamping a fixture plate onto a receiver plate using locating pins that pass into aligning bores on both the fixture plate and the receiver plate. Each locating pin has a cylindrical body with a flange or head on one end and a cone surface at the other end. An axially slotted sleeve with two internal cones is provided in the bore of the receiver plate. A screw with a cone nut is passed through the locating pin so that the nut is on the opposite end of the slotted sleeve from the locating pin. When the cap screw is tightened, one end of the slotted sleeve engages a cone on the pin and the other end of the slotted sleeve is engaged by a cone surface on the nut, to expand as it moves in direction toward the flange and lock the slotted sleeve in place in the bores of the receiver plate. The flanges or heads of the locating pins engage the outer surface of the fixture plate and as the cap screw is tightened, the flanges or head will force the fixture plate against the receiver plate. The flanges have orientation pins held in holes in the fixture plate for identifying and keeping the locating pins from rotation during tightening and untightening of the cap screw.
