An adjustable locator includes a locator element for contact with a workpiece supported on a fixture. The locator comprises a support element in which a ramp element is slidable. The ramp element has a ramp surface which is contacted by a plunger which carries the locator element. Displacement of the ramp element causes displacement of the plunger to adjust the position of the locator element with respect to the support element. A ratchet mechanism permits displacement of the ramp element in one direction, but prevents such movement in the opposite direction. The adjustable locator can be used in a workpiece fixture to achieve an optimum orientation of a workpiece prior to machining. |
