20210107054 · 2021-04-15 ·

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.

Method of joining two components, auxiliary joining part and components assembly

A method of connecting a first component and a second component with the aid of an auxiliary joining part, wherein the auxiliary joining part is formed from a pin and a plate. A position of intended fracture is present between the plate and the pin. The first component, the second component and the auxiliary joining part are brought into a stacked arrangement such that the plate contacts the first component and the pin projects away from the side of the plate remote from the first component. A force is exerted on the pin of the auxiliary joining part in the direction towards the stacked components which leads to a fracture at a position of intended fracture and the pin is used in order to pierce slugs from the stacked components. The end of the pin which is pressed through the second component, and/or a washer which is optionally provided there, is deformed in order to provide a form-locked connection to the second component or to a washer which is provided there. Furthermore, an auxiliary joining part is claimed.

Collar positioning system

A method and system for installing a fastener system. A collar in the fastener system is automatically positioned on a hole on a first side of a structure prior to an insertion of a pin in the fastener system into the hole from a second side of the structure in which the pin has a pin tail. The pin with the pin tail is inserted through the collar in which the pin extends through the hole and the collar. A force is applied on at least one of the collar or the pin tail along a centerline extending centrally though the collar until the pin tail becomes separated from the pin such that the collar engages an engagement feature on the pin when the pin with pin tail is inserted into the hole from the second side.

Dynamic collar swage conformance checking based on swage tool parameters

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.

Installation tool for a blind fastener and installation procedure for a fastener

An installation tool for a fastener of the pull screw type, comprising a breakable gripping element includes a body, a first sleeve movable axially and rotationally in the body that can drive the gripping element, a second sleeve movable axially in the body and immovable in rotation, and a driving device provided with a turning shaft. The shaft comprises a first free wheel for driving the first sleeve in rotation, a second free wheel, and a driving element positioned coaxially around the second free wheel. The driving element cooperates using a helical link with the second sleeve. The first free wheel drives the first sleeve in rotation in a first rotation direction of the shaft. The second free wheel brings the driving element in rotation in a second rotation direction of the shaft to move the second sleeve axially, allowing full setting in a single operating sequence.
