ABSTRACT:
A pallet changer and a system and a method for using the same attach, secure and/or connect a part and/or pallet assembly to a receiver assembly for machining the part. A groove and/or a pull post of the pallet assembly is insertable between a first wedge arm and a second wedge arm in an interior of the receiver assembly. Springs within the interior of the receiver assembly exert forces against the first wedge arm and the second wedge arm to maintain the first wedge arm and/or the second wedge arm in a first position within the interior of the receiver assembly. A key and/or a cam moves and/or rotates to move the first wedge arm and/or the second wedge arm from the first position to a second position. A first tapering on the pallet assembly engages and/or corresponds to a second tapering on the first wedge arm and/or the second wedge arm to secure and/or to attach the pallet assembly to the receiver assembly in the second position. A first plate attached to the interior of the receiver assembly prevents the cam from rotating the first wedge arm within the interior of the receiver assembly. A second plate connected to a passage of the receiver assembly prevents the key from being removed from the receiver assembly with the first wedge arm and/or the second wedge arm in the first position.
