摘要： Lockbolt collar feed mechanisms, lockbolt installation tools, and methods of installing lockbolt assemblies are disclosed. Lockbolt collar feed mechanisms comprise a collar cartridge and a mounting bracket operatively coupled to the collar cartridge and configured to be operatively coupled to a lockbolt installation tool. The collar cartridge has a delivery position, in which an exit port is positioned to position a lockbolt collar forward of the lockbolt installation tool's anvil, and a retracted position, in which the collar cartridge is pivoted and translated rearward relative to the delivery position. The collar cartridge is biased toward the delivery position and moves from the delivery position to the retracted position responsive to a user urging the lockbolt installation tool and the lockbolt collar feed mechanism toward and into engagement with a workpiece.

摘要： A method of delivering a collar between a fastener and a swager is provided. The method comprises steps of: (i) advancing the collar from a collar source to a collar feeder, where the collar source is operatively coupled to the collar feeder via a collar-supply tube, (ii) presenting the collar at an outlet of the collar feeder concentrically in line with a central axis of the fastener and with a working axis of the swager, and (iii) retaining the collar at the outlet of the collar feeder using at least one resilient flexure of the collar feeder.

摘要： Two piece tack rivets and method of forming holes for permanent fasteners. The tack rivets have a stem with a head on one end and a grooved region adjacent the other end, and a locking collar for fitting over the grooved region of the stem for deforming into the grooved region of the stem on applying a setting force between the locking collar and the stem. The head includes cutouts formed therein. The cutouts prevent the head from forming large chips or strips when drilled.

摘要： A reusable single groove riveting system includes a single groove riveting bolt and a collar, and a method of use thereof as well as installation and removal methods thereof. A pull groove has a variable section feature along the axial direction so a collet and the single groove can automatically align during installation; the variable section can reduce the stress concentration effects along the single groove structure and avoid stuck problems. While raising the strength of the collar flange, the design feature of the axial installation force indicator is added. The single groove structure will not receive any extra load from the tool during disassembly or removal process so the rivet bolt can be reused after the disassembly. In the event the bolt pull groove is accidently damaged or the work space is limited, the collar can be effectively removed from the joint with this disassembly or removal method.

摘要： A fastening system including a fastener and a fastener installation tool. The fastener includes a pin member having an elongated shank portion with a threaded portion, a stop shoulder located at an end of the threaded portion, and a pull portion extending from the stop shoulder. The stop shoulder includes an outer rim and an inner annular wall. The inner annular wall and the inner face form an annular recess. The fastener installation tool includes a puller having a front face. The recess of the fastener is adapted to receive the front face of the fastener installation tool when the puller engages the pull portion of the pin member and facilitates alignment of teeth of the installation tool and pull grooves of the pin member.

摘要： The present invention relates to a nose assembly with integrated anvil and puller to assist in swaging a collar to a lockbolt type fastener. The nose assembly has a sidewall defining a hollow axially extending interior and an open terminal end, hollow axially extending interior having a first interior diameter, and an annular recess of a second interior diameter greater than the first interior diameter. A puller is slidably displaceable relative to the holder sidewall. The puller is configured with opposing sets of teeth for gripping a lockbolt pintail and to close grippingly on the lockbolt pintail when the puller is axially displaced relative to the holder sidewall sufficiently to draw a head portion of the puller at least partially out of the recess and into the first interior diameter length.

摘要： A fastening system including a fastener and a fastener installation tool. The fastener includes a pin member having an elongated shank portion with a threaded portion, a stop shoulder located at an end of the threaded portion, and a pull portion extending from the stop shoulder. The stop shoulder includes an inner annular wall extending longitudinally from the end of the threaded portion, and an inner face extending outwardly and obliquely from the shank portion. The inner annular wall and the inner face form an annular receiving area. The fastener installation tool includes a puller having a front face. The receiving area of the fastener is adapted to receive the front face of the fastener installation tool when the puller engages the pull portion of the pin member.

摘要： The self-locking collar comprises a sleeve having a thick wall portion and a thin wall portion which has a thinner wall than the thick wall portion and a step portion between the thick wall portion and the thin wall portion; and a flange adjacent the thick wall portion of the sleeve. A through hole penetrates through the flange and the sleeve. The sleeve is inserted into a mounting hole of a resin component, the thin wall portion is collapsed to form a collapsed portion, and the resin component is sandwiched between the flange and the collapsed portion. The outer diameter of the thin wall portion is D, the wall thickness is t, the length is L, the Poisson ratio is γ, and: r = ( D - t ) / 2 ; m = L π 4 r 2 t 2 12 ( 1 - γ 2 ) ; and 1.2
