The invention relates to a riveting tool for setting blind rivet nuts and/or blind rivet screws, comprising a drive piston which is able to be hydraulically adjusted from an initial position toward an end position, a pull rod which is releasably and operatively connected to the drive piston and which is able to be adjusted by the drive piston from a rivet receiving position into a setting position and a coupling element fixing the pull rod and a drawing mandrel to one another in the longitudinal axial direction. In order to provide a riveting tool of the type mentioned above by which uniform setting processes of rivets may be carried out with a high degree of repeated accuracy, it is provided that the riveting tool for fixing the setting position has an adjusting unit with a stroke-limiting element which is axially adjustable relative to the coupling element in the longitudinal axial direction of the pull rod, said stroke-limiting element being in engagement with the coupling element via a stop surface in the setting position.

The present invention discloses a one-hand-handled rivet gun, which has a handle seat with a through hole, a folding mechanism hinged to the handle seat and a pulling rod connected to the folding mechanism. The mentioned pulling rod is coated by a housing, and is equipped with a riveting gun tip assembly on the front end. A fixed sleeve is mounted on the front end of the housing of the pulling rod, and a guiding nipple is mounted on the front end of the fixed sleeve. The mentioned folding mechanism comprises two folding rod assemblies symmetrically mounted behind both sides of the rear end of the pulling rod, and the two folding rod assemblies include a front curved link and rear curved link hinged to each other. A handle cover is connected to the rear end of the rear curved link, and the front curved link is fixed to the pulling rod by the front end and hinged to the front end of the handle seat. Therefore, the invented one-hand-handled rivet gun can be used with only one hand, which is easy for people to use.

The invention relates to a riveting tool for setting blind rivet nuts and/or blind rivet screws, comprising a drive piston which is able to be hydraulically adjusted from an initial position toward an end position and a drawing mandrel which is able to be brought releasably into operative connection with the drive piston and is able to be adjusted by the drive piston between a rivet receiving position and a setting position. In order to provide a riveting tool of the type mentioned in the introduction, uniform setting processes of rivets being able to be carried out thereby with a high degree of repeated accuracy, it is provided that the riveting tool for fixing the setting position of the drawing mandrel comprises a setting unit comprising a stroke limiting element which is able to be adjusted in the longitudinal axial direction of the drive piston and which is able to be brought into engagement with the drive piston.

A tooling installation system having unique tools which provide an external force directly to the sleeve end of a faster to create a bulb on the sleeve of the fastener is provided. The system provides external forces directly to the sleeve end of the fastener deforming a portion of the sleeve radially outward and onto the structure prior to swaging a second portion of the sleeve radially inward onto the pin. Additionally, the system controls formation of the sleeve by capturing an external portion of the sleeve creating a cavity between the tool and the structure for achieving proper bulb formation during installation prior to swage. The system also provides specific forces to the head of the pin and the head of the sleeve to insure proper seating of the fastener head against the structure inducing residual compressive stresses within the structure, thus improving mechanical properties such as fatigue life of the structure.

A hand-held knockout driver includes a main housing having a handle portion, a motor positioned within the main housing, a pump assembly driven by the motor, and a secondary housing coupled to the main housing and defining a bore therein. The hand-held knockout driver also includes a working piston moveable within the bore from a rest position to an actuated position to define a piston throw distance therebetween. The hand-held knockout driver also includes a draw stud coupled to the working piston, a die coupled to the secondary housing, and a punch coupled to the draw stud opposite the working piston for movement therewith relative to the die. The die has a depth greater than the piston throw distance.

A fastener installation tool includes a nose assembly, first and second cylinders, first and second pistons, and a yoke. The nose assembly is adapted to apply an axial load to a fastener along a longitudinal axis of the nose assembly. The first and second cylinders are diametrically opposed to one another with respect to the longitudinal axis of the nose assembly. The first piston is disposed within the first cylinder and is movable along a longitudinal axis thereof. The second piston is disposed within the second cylinder and is movable along a longitudinal axis thereof. The yoke connects the first piston, the second piston, and the nose assembly such that motion of one of the pistons along its corresponding longitudinal axis causes motion of the other one of the pistons along its corresponding longitudinal axis and motion of at least a portion of the nose assembly along its longitudinal axis.

The invention relates to a processing clamp for machining and/or processing of workpieces with large processing forces, including a clamp body with a first clamp arm and a second clamp arm and at least a tool with a first tool part and a second tool part which are movable relative to each other and define a working region. The first tool part is arranged to be traversable along a vertical tool axis on the first clamp arm to close the working region and the second tool part is arranged on the second clamp arm to form a workpiece abutment for at least one workpiece. The first tool part is adjustable from a starting position into a working position by an adjustment device. An actuating device is provided for applying a high processing power acting along the tool axis to the first tool part after the adjustment into the working position by the adjustment device.

A system and method for drilling a hole in a vehicle structure and installing a fastener in the hole. A drill plate having openings and associated machine-readable elements is positioned on the structure. A drill gun is positioned in a particular opening and reads hole information from the associated element, and a computer determines whether the drill gun is properly set-up to drill the hole. A fastener insertion gun is positioned in the particular opening and reads fastener information from the element, and the computer determines whether the hole has been drilled and, if so, whether the fastener insertion gun is properly set-up to insert the fastener. A fastener delivery subsystem stores, tracks, and delivers fasteners to the fastener insertion gun. A system computer monitors the drilling of every hole, the insertion of every fastener, and the overall operation of the fastener delivery subsystem.
