Abstract
The subject invention provides a locating assembly for centering and securing a work piece. The locating assembly includes a body. The body defines an internal cavity and an opening from the cavity to the exterior of the body. A locating pin is disposed in the cavity and extends along an axis out of the opening. An actuator moves the locating pin rectilinearly along the axis. A pair of fingers are supported by the locating pin and move radially into and out of the locating pin, transversely to the axis. A central post rotates in response to the rectilinear movement of the locating pin. A dowel extends from an end of the central post into a slot in the finger. The central post moves the dowel in an arcuate path through the slot to radially move the finger simultaneous with the rectilinear movement of the locating pin.
