  • Patent number: 9199295
    Abstract: An apparatus for roller swaging may include a support arm, a spherical roller rotatably supported in the support arm, a mount for slidably supporting the support arm, a first actuator for displacing the support arm relative to the mount, a second actuator for supporting the arm and imparting rotational movement of the mount about an axis in which the spherical roller describes a circular path, a base for supporting the second actuator for reciprocal movement parallel to the axis, and a third actuator connected to the second actuator for displacing the second actuator relative to the base. A method for roller swaging may include inserting a tube end into a ferrule, and urging a spherical roller against an inner wall of the tube with a force sufficient to swage the inner wall against the ferrule, thereby mechanically securing the ferrule to the end of the tube.
