摘要： A fastener application device comprising an hydraulically-operated tool head held by an operator and having an actuator trigger, a base structure having an air-operated power cylinder operatively attached to an hydraulic cylinder to supply hydraulic pressure to the tool head in response to operation of the actuator trigger. The tool head and base structure are connected only by air and oil lines that are long enough to allow the base structure to be supported on, for example, a workbench, requiring the tool operator to support only the weight of the tool head during a fastener installation sequence.

摘要： A fastening method for fastening using a fastener having a fastener pin and a collar. The method includes a mounting step in which, in a state in which a head portion of the fastener pin is positioned on one side of the portion to be fastened through which the fastener pin is passed, and a lock portion of the fastener pin is positioned on the other side of the portion to be fastened, the collar is mounted onto lock grooves. The method includes a fastening step in which, on the basis of an un-swaged portion height derived from the thickness of the portion to be fastened, the collar is swaged onto the lock grooves and the portion to be fastened is fastened.

摘要： An assembly comprising first and second structural elements having aligned holes, a fastener that occupies at least respective portions of the holes without a surrounding sleeve, and a mating part that is coupled to the fastener. The fastener comprises: a head; a circular cylindrical shank extending from the head; a mating portion comprising external projections; and a transition portion disposed between the shank and the mating portion. The transition portion comprises a tapered lead-in section that meets the shank at a shank/lead-in intersection and a radiused lead-in section that meets the tapered lead-in section. The tapered lead-in section tapers gradually in a first axial direction toward the mating portion and has a first profile that is linear and a taper angle equal to or less than 20 degrees, while the radiused lead-in section curves abruptly in the first axial direction and has a second profile that is a circular arc having a radius.

摘要： Systems and methods are provided for inspecting fastener installation. One embodiment is a method for inspecting installation of a fastener. The method includes determining an initial distance between a nose of a swage tool and an Inner Mold Line (IML) of a part, operating the swage tool to swage a collar onto a fastener that protrudes through the IML of the part, determining a terminal distance of the nose to the IML during swaging, prior to a pintail of the fastener breaking, and arriving at a conclusion indicating a state of a fastener installation, based on the terminal distance.

摘要： A double ended dual attached fastener includes a first portion having a stud bolt, a second portion configured to anchor to a panel member, and a flange nut partitioning the first end and the second end. The flange nut includes a flat interior annular surface facing the second portion. The flange nut includes a plurality of radially spaced weld projections extending toward the second portion. The weld projection includes a material that amendable to form a weld joining the flange nut to a panel member through which the second portion is inserted. The second portion defines a fastener selected from a group consisting of a self-tapping friction screw, a self-piercing rivet, and a swage bolt.

摘要： 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.

摘要： A method for the connection of moulded parts, wherein a locking collar pin with locking grooves or with an external thread, is driven through the moulded parts and subsequently a locking collar is locked together with at least some of the locking grooves, or with threaded sections of the locking collar pin, by the application of radial pressure, or by means of a screwing operation. A connecting system with a locking ring pin, which has a punching section for purposes of punching through the moulded parts, and also locking grooves for purposes of active engagement with a locking ring; the latter extends over at least two adjacent locking grooves in the axial direction, or over at least two adjacent threads in the axial direction.
