A positioning device for a workpiece that has a body and a portion that is movably mounted to the body. The positioning device includes an abutment assembly having a first and second abutment member. The positioning device also includes an actuator assembly adapted for moving the abutment assembly between a locating position, in which the first abutment member is disposed adjacent the exterior surface of the portion of the workpiece while the second abutment member is disposed in the exterior space defined by the portion, and an inserted position, in which the second abutment member is disposed in the portion while the first abutment member is disposed in the exterior space defined by the portion. The actuator assembly is further adapted to move the portion relative to the body due to abutment between the portion of the workpiece and at least one of the first and second abutment members.
