ABSTRACT:
A locking mechanism for a locating and clamping fixture is provided, wherein the locking mechanism comprises a drive pin that is linearly positionable along a first axis. The drive pin comprises a driver portion and a driven portion, wherein the driver portion is coupled to a piston of the fixture and the driven portion is coupled to a clamping arm of the fixture. The driver portion of the drive pin further comprises an annular groove, wherein one or more rollers are associated with the annular groove of the drive pin and a body of the fixture. The one or more rollers are operable to generally maintain a position of the clamping arm upon a loss of a driving force to the driver portion via an interface between the one or more rollers, the drive pin, and the body.
