Rotatable offset nose assembly for setting fasteners

摘要

An offset nose assembly for swaging a fastener collar about a fastener pin includes an anvil housing which is rotatably mounted within a tubular sleeve portion of a hydraulically actuated installation tool. A collet is slidably fitted within the anvil housing and is connected to a piston of the installation tool via a smooth-walled drawbar and tubular adapter coupling. The drawbar is received within smooth-walled bores formed within the collet and the tubular adapter coupling. The tubular adapter coupling is closely fitted within a tubular portion of the anvil housing and is adapted to be securely fixed to the reciprocating piston of an installation tool. The anvil housing is mounted to the installation tool with a split ring and fastening nut in a manner which ensures an axial clearance is maintained between the installation tool and the anvil housing thereby providing free rotational movement of the anvil housing around the tool.
