Workpiece support tool

摘要

An improved workpiece support tool is disclosed for use with a variety of workpieces. The support tool provides precise support and positioning of the workpiece with respect to an operational centerline during the balancing operation. The support tool includes a plurality of radially moving jaw members which are driven by an inverted cone-shaped drive member. The inverted cone-shaped drive member is moved along the axis of the support tool through driving forces imparted by a servo drive motor.
