ABSTRACT:
A locator assembly for locating one end of a part on a fixture gauge includes a fixed portion (20, 22) having a central circular cavity therein, a movable portion (24, 26, 28) slidably captured within the cavity (30), and a locator pin (35) axially shiftable within a central opening in the movable portion. The fixed portion comprises three plastic plates sandwiched together, wherein a central opening of the middle plate is smaller in diameter than the central openings of the outer plates. The movable portion likewise includes three additional plates sandwiched in face-to-face contact with each other with respective, concentric central openings therein for receiving the locator pin therethrough. The locator pin is therefore longitudinally slidable along its axis and includes an annular shoulder (38) for engaging and aligning one end of the part. The movable portion is captured and slidable within a recess in the fixed portion so that the locating pin can be moved in a plane perpendicular to the longitudinal axis of the pin in order that the pin may be used to properly locate the part on the fixture.
