ABSTRACT:
Precise and fastenerless connection of a fixture to rotatable headstock and tailstock positioners is provided by a slidably engageable ball and socket arrangement located on the headstock positioner and on one end of the fixture, and by a tapered roller located at the opposite end of the fixture which is cradled between two grooved rollers located on the tailstock positioner. The ball and socket centers the headstock end of the fixture on the rotational axis of the headstock positioner while the tapered roller and grooved rollers locate the fixture linearly as well as centrally. The overall fixture support arrangement permits misalignment of the headstock and tailstock positioners without binding of the fixture. A second slidably engageable connecting device at the headstock end assures precise rotaton of the fixture in unison with the headstock positioner.
