Patent number: 10391545Abstract: Provided are self-aligning riveting tools and methods of utilizing such tools for installing rivets. A tool includes an aligning sleeve, which is slidably coupled to a first die. Furthermore, the tool includes a die holder, which is slidably coupled to a second die. During operation, the aligning sleeve is positioned over the rivet head thereby axially aligning the first die relative to the rivet, even before the first die contacts the rivet head. The second die contacts the rivet shank end thereby axially aligning the rivet relative to the second die and the die holder. Advancing the die holder toward the first die first clamps the rivet in the tool and then proceed with forming the rivet tail. The rivet remains coaxial with both dies during all of these operations.Type: GrantFiled: March 17, 2017Date of Patent: August 27, 2019Assignee: The Boeing CompanyInventors: Pradeepan Kuniyil, Blair Larsson

Patent number: 10220435Abstract: A tooling installation system having unique tools which provide an external force directly to the sleeve end of a faster to create a bulb on the sleeve of the fastener is provided. The system provides external forces directly to the sleeve end of the fastener deforming a portion of the sleeve radially outward and onto the structure prior to swaging a second portion of the sleeve radially inward onto the pin. Additionally, the system controls formation of the sleeve by capturing an external portion of the sleeve creating a cavity between the tool and the structure for achieving proper bulb formation during installation prior to swage. The system also provides specific forces to the head of the pin and the head of the sleeve to insure proper seating of the fastener head against the structure inducing residual compressive stresses within the structure, thus improving mechanical properties such as fatigue life of the structure.Type: GrantFiled: August 26, 2016Date of Patent: March 5, 2019Assignee: POLARIS FASTENER TESTING AND TOOLING, LLCInventors: Rahmatollah F. Toosky, Nicholas A. Elliott

Patent number: 6546613Abstract: The present invention provides a novel anvil for a rivet setting machine configured to drive a rivet into a workpiece within a riveting process. The anvil has a cavity therein configured to accommodate a deformation of the rivet and the workpiece during the riveting process. The cavity is defined by a main portion configured to support the workpiece during the riveting process and a relief portion that is proximate to the main portion. The relief portion is configured to provide an area into which the workpiece and the rivet deform during the riveting process. The relief portion includes at least one relief pocket configured to maintain an area which remains unoccupied by the workpiece and the rivet throughout the entire riveting process. The relief portion does not substantially hinder the workpiece and rivet during the riveting process and allows the workpiece and rivet to freely deform during the riveting process.Type: GrantFiled: August 29, 2001Date of Patent: April 15, 2003Assignee: Textron Inc.Inventor: Steven P.

Patent number: 6279371Abstract: A hand-held tool for forming a rivet head at the plain end of a rivet includes an elongated handle having an elongated internal cavity with a guide wall surface extending to an adjacent guide wall surface in an insert having an end wall. The end wall is provided with a predetermined thickness and contains an aperture to house a shop head formed on the plain head of a rivet. An inertia block is slidably guided by the guide wall surfaces of the handle and insert for reciprocation between a displaced position remote from the end wall and a position for contact with the end wall. A spring located in the elongated handle urges the inertia block against an end of a rivet when protruding from the aperture in the end wall and arrests recoiling movement of the inertia block after impact with a rivet end in a direction away from the end wall.Type: GrantFiled: April 24, 2000Date of Patent: August 28, 2001Inventor: Robert Brewer
