Abstract
An improved mandrel chuck for the backstop assembly of a friction welding machine holds a first interiorly lobed workpiece as a second rotating workpiece is displaced into forceful engagement therewith. The improved chuck comprises a main body portion, an end portion rigidly fixed to the main body portion, and an intermediate portion mounted between the main body portion and the end portion, all of the chuck portions having similar exterior lobes in a configuration which complements the interior lobes of the first workpiece. A hydraulic actuator rotates the intermediate portion relative to the main body and end portions to interiorly grip the first workpiece wherein one end of the first workpiece projects from and is proximate to the chuck end portion, whereby the chuck will not contribute to any outward bowing or distortion of the workpiece end.
