Fastening collar installation apparatus and methods of installing a fastener system are provided. The fastening collar installation apparatus comprises an anvil, a sleeve, and a lever. The sleeve comprises a first section comprising a first sleeve end and a second sleeve end, a sleeve cavity, and a slot. The first sleeve end is intermediate the anvil and the second sleeve end. The slot extends a first distance from the first sleeve end. The lever is slidably received by the slot of the sleeve and configured to move between a first lever position in the slot and a second lever position in the slot. The lever comprises a second distance from a first lever end to a second lever end. The second distance is less than the first distance.

A robot vision-based automatic rivet placement system and method. The automatic rivet placement system includes: an industrial robot installed on a frame, a multi-functional end effector, a rivet blowing mechanism, a detection disk, and a rivet holding tray. The multi-functional end effector consists of a flange disk, a support frame, an industrial CCD camera, a laser displacement sensor, a spring, a mixing rod, and a vacuum nozzle. The multi-functional end effector is connected to a terminal end of the industrial robot via the flange disk. The industrial CCD camera is installed directly in front of the support frame, and is used to acquire a rivet image and measure a rivet parameter. The laser displacement sensor is installed at a side surface of the support frame, and is used to measure a rivet depth.

Resistance spot rivet welding systems, subsystems, and methods of use thereof are provided.

A device is disclosed for supplying swageable collars from a magazine to a swaging tool such that the collars may be affixed to the shanks of lockbolts in a series of application steps. The feeder device can be mounted on the nose assembly of a swaging tool so that collar feeding and swaging can be accomplished in a single-handed operation. The feeder device responds to contact pressure against a work surface during a collar placement maneuver to release a collar from a presentation position for normal swaging. Releasing pressure on the workpiece allows a lower assembly of the feeder device to lift the next collar available from a magazine into the presentation position for application to the next lockbolt shank in a series of lockbolts to be finished.

The invention relates to a method for screwing a locking ring (1) onto a threaded bolt (2), wherein a coupling device (6) for being threaded into the threaded bolt (2) is driven in rotation by a rotary drive (4), and wherein the locking ring (1) is then screwed onto the threaded bolt (2), which is fixed by the coupling device (6), by a locking ring holder (3) which is driven in rotation by the rotary drive (4). The invention likewise relates to a method for screwing a locking ring (1) comprising a fastening part (18a) and a tear-off part (18b) onto a threaded bolt (2), wherein a removal gripper (22) grips the tear-off part (18b) and removes the tear-off part (18b) after the tear-off part (18b) has been torn off. The invention further relates to a screwing apparatus for executing a method according to the invention.

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.

A feed assembly for a foot-pedal operated riveter and a method of using the same is disclosed. The feed assembly includes a rivet stop that has a tip that separates a lowermost fastener from a second from lowermost fastener when the riveter is in a non-operational position. This rivet stop prevents fasteners from sliding down a raceway on the feed assembly. When the riveter is moved into an operational position, the rivet stop moves out of the way and permits the second from lowermost fastener to slide into position for subsequent installation. The rivet stop thus enables automatic reloading of the riveter during operation.
