    摘要: A blind fastener includes a sleeve defining a sleeve central axis and having a sleeve shank having a distal end portion and a proximal end portion axially opposed from the distal end portion and a stop connected to the distal end portion of the sleeve shank. The sleeve defines an eccentric through-bore that extends along a through-bore axis from the proximal end portion to the distal end portion. The blind fastener includes a core bolt at least partially received in the eccentric through-bore of the sleeve, defining a core bolt central axis. A core bolt shank has a distal end portion, a proximal end portion axially opposed from the distal end portion, and a threaded portion. A core bolt head is connected to the proximal end portion of the core bolt shank. An eccentric nut is threaded into engagement with the threaded portion of the core bolt shank.

    摘要: Systems, methods, and apparatus for a detector and reflector for automation cell safety and identification are disclosed. In one or more embodiments, a method for machinery safety comprises transmitting, by an active transponder, at least one interrogation signal. The method further comprises receiving, by at least one passive transponder located on a user or on an item, the interrogation signal(s). Also, the method comprises generating, by a non-linear device of the passive transponder(s) in response to the interrogation signal(s), at least one response signal. In addition, the method comprises receiving, by the active transponder, the response signal(s). Additionally, the method comprises determining, by at least one processor, a location of the passive transponder(s) based on the response signal(s). Further, the method comprises determining, by the processor(s), whether the passive transponder(s) is located within a threshold distance away from machinery by using the location of the passive transponder(s).

    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: A compound contour vacuum track, and an automated fastening machine using the track, for automation of final assembly inside an aircraft fuselage. The track is mounted at an angle to a surface, such as an inside surface of the fuselage, wherein the surface has one or more holes through which fasteners are inserted. The automated fastening machine is mounted on the track to traverse the track while performing fastening functions and steps. The automated fastening machine includes a carriage, arm, and end effector, wherein the arm is mounted on the carriage and the end effector is mounted on the arm. The carriage is attached to the track for positioning the arm and end effector, the arm is attached to the carriage for positioning the end effector, and the end effector is attached to the arm for installing the fasteners into the holes of the surface.

    摘要: A method for installing a flexible track system is presented. At least one of a number of heights or a number of angles is selected for a variable height base system that connects a base attaching system and flexible tracks in the flexible track system to each other, wherein at least one of the number of heights or the number of angles for the variable height base system maintains at least one of a desired distance between the flexible tracks and a surface of a structure to which the base attaching system is attached to the flexible tracks in the flexible track system matching a contour of the surface of the structure. The flexible track system is attached to the surface of the structure.

    摘要: An electromagnetic effect suppressing termination part is provided for a fastener formed of a metallic material, the fastener having a head, a shank, and a threaded portion opposite the head. The termination part includes a main body defining an internally threaded portion configured to threadably receive the threaded portion of the fastener, the internally threaded portion defining a thread major diameter. A collar is coupled to a distal end of the main body by a frangible web, wherein the main body, collar, and frangible web are formed of a metallic core coated by a layer of dielectric material. The frangible web, when broken, presents an exposed portion of the metallic core, wherein the frangible web includes an inner surface radially outwardly offset from the thread major diameter of the internally threaded portion by a setback distance.
