A collar has a flange and a collar body that is swaged into the center section of the retainer pin.

A hydraulic fastener tool comprising with a piston in threaded connection with a single-unit puller that is inside a single-unit anvil. Inside the puller is a segmented collet assembly with an internal spring and guide tube. In use, the tool secures fasteners and ejects the severed fastener stem after fastening.

A fastening member for fastening two or more components, ensuring a high degree of freedom in terms of fastening positions and objects, reducing the number of holes, preventing the rotation of the components and the fastening member in one-point fastening, and maintaining high strength and resistance against vibration after fastening. Specifically, a fastening structure for fastening the first and second components, which comprises a first component, a pin that has non-helical grooves running in a circumferential direction and aligned along a longitudinal direction and whose one end in the longitudinal direction is bonded to the first component, a second component that has an insertion hole for inserting the pin, and a collar that is fitted around and bonded to the pin so that the second component is positioned between the collar and the first component, wherein said second component is prevented from rotating with respect to said pin.

The assembly includes an insert retainer having a retainer head and a retainer pin. The retainer pin has an upper section extending below the retainer head and a grooved center section below the upper section. A valve is centered on the upper section of the retainer pin. An insert is located on the valve. A guide has a central portion centered on the upper section of the retainer pin and four legs extending from the central portion. A collar has a flange and a collar body that is swaged into the center section of the retainer pin.

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

A connection system for connection of two or more overlapping layers of material includes: a rivet having a head and a stem, the head being configured to bear upon a surface of a first layer of the layers of material, the stem having an outer surface that includes a surface sculpturing and being configured for passing through the layers of material and projecting beyond them; and a washer configured to fit on the stem and configured to bear upon a surface of a last layer of the layers of material, the washer being deformable by axial compression from an undeformed condition where it fits on the stem with play, to a deformed condition where it fits on the stem in a condition of interference with the outer surface of the stem. Moreover described is a corresponding method for joining the layers of material using the connection system.

The present invention discloses a riveting robot, comprising: a robot part provided on a chassis, and detachably coupled with a riveting tool part through a hydraulically quick change disk; a visual position identification part provided on a side of the hydraulically quick change disk and secured on the sixth axis of the front end of the robot part; an automatic rivet feeding part provided on a mounting baseplate which is secured on a chassis through a two-stage vibration damping structure; a riveter tailing material collection part used for collecting tailing materials produced during riveting; a riveting quality judgment part used for collecting riveting data, and processing and generating a riveting curve to realize judgment of the riveting quality.

Systems and methods are provided for fastening via a swage tool. One embodiment is a method for fastening via a swage tool, the method including selecting a hole located at a part; aligning an axis of a lockbolt collar with a center of the hole; placing the lockbolt collar flush against the part at a first end of the hole; and swaging the lockbolt collar onto a lockbolt that has been driven through the hole.

A fastening tool includes a fastener-abutment part, a pin-gripping part, a motor, a driving mechanism, an input-accepting part and a motor-control part. The fastener-abutment part is configured to abut on a cylindrical part of a fastener. The pin-gripping part is configured to grip a portion of a pin of the fastener. The driving mechanism is configured to be driven by power of the motor to move the pin-gripping part rearward along a driving axis relative to the fastener-abutment part, thereby fastening a workpiece via the fastener. The input-accepting part is configured to accept setting information for a control condition of the motor inputted via an operation part configured to be externally operated by a user. The motor-control part is configured to control operation of the driving mechanism by controlling driving of the motor according to the control condition based on the setting information accepted by the input-accepting part.

A fastening tool includes a bolt-gripping part, an anvil, a motor, and a control part. When the bolt-gripping part grips an end region of a shaft part and moves relative to the anvil in a first direction of a longitudinal-axis direction, the anvil presses a collar fitted onto the shaft part in a second direction opposite to the first direction of the longitudinal-axis direction and inward in a radial direction of the collar, so that a hollow part of the collar is crimped to a groove while the workpiece is clamped between the collar and a head part, whereby swaging of a fastener is completed while the end region remains integrated with the shaft part. The control part completes swaging of the fastener by terminating a movement of the bolt-gripping part in the first direction relative to the anvil based on driving current of the motor.
