Systems and methods are provided for fastening via a swage tool. One embodiment is a method for fastening via a swage tool. The method includes steps of 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. This securely fastens the lockbolt collar to the lockbolt.

An intelligent riveting system comprising a hydraulic riveting tool (1), a riveting position identification system, a riveting displacement detection system, a riveting pressure detection system and a central processing system, wherein the central processing system acquires image information and carries out position identification, encoding and storage to form riveting position data in one-to-one correspondence, acquires real-time displacement data and riveting oil pressure data of each riveting position to form real-time data corresponding to riveting displacement values and riveting pressure values, and compares same with a standard to carry out quality determination. By means of the intelligent riveting system, a riveting position and an installation parameter are automatically identified and acquired, and the riveting quality is automatically determined; and by means of storing data during riveting and installation, the traceability of rivet installation quality can be achieved.

The invention relates to a hold-down device for a joining drive and joining drive with a hold-down device. The hold-down device includes a hold-down cylinder, wherein the hold-down cylinder provides a hold-down force by means of a pressurized chamber. The pressure chamber consists of the hold-down cylinder and a punch of the joining drive. The pressurization required for the provision of the hold-down force is provided by a hydraulic circuit of the joining drive. In the joining mode, the pressure chamber of the hold-down device is connected to a pressure accumulator of the hold-down device, so that a change in volume in the pressure chamber of the hold-down device has no noticeable influence on the pressure in the pressure chamber.

A device and the method serve to set a connecting element, in particular a press-in bolt, on a workpiece. By means of a setting unit, a hole punching operation for introducing a hole and, at the same time, a hole-forming operation are carried out, in which an edge of the hole is deep-drawn using an embossing sleeve and a collar is formed. In a second stage, the connecting element is pressed in, the punching and hole-forming operation and the pressing taking place within the same axial axis without the workpiece being laterally displaced relative to the 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.
