Pneumatic- Or Fluid-actuated Tool Patents (Class 29/243.523)
  • Patent number: 10751790
    Abstract: A linear actuator assembly comprises a housing, an output shaft, a nose piece and a negative pressure device. The output shaft defines an actuator assembly axis, and is movable along the actuator assembly axis between an extended position and a retracted position relative to the housing. The nose piece is slidably mounted to the output shaft and movable between an extended position and a retracted position relative to the output shaft. The nose piece and the output shaft co-operatively define a chamber for containing a quantity of fluid, the volume of the chamber being smaller when the nose piece is in the retracted position than when the nose piece is in the extended position. The negative pressure device is connectable to the chamber, and is selectively operable so as to reduce the pressure in the sealed volume, thereby urging the nose piece from the extended position towards the retracted position.

  • Patent number: 8925166
    Abstract: A rivet setting device contains in a housing a receiving chamber in which a break-off rivet mandrel is situated after the setting operation. Arranged in this receiving chamber are two elongate magnets which leave free between them a space for the residual mandrel and which attract the residual mandrel from the holder for the rivet after it has been broken off and retain it. The holder for the residual mandrel can be moved with a transverse component in the device, with the residual mandrel being moved past a stripping element into a region outside the axis of the holder for the rivet. During the rearward movement of the residual mandrel holder, the residual mandrel is stripped off and remains in a collecting chamber.

  • Publication number: 20070113390
    Abstract: A rivet set quality monitoring system is disclosed. A supply pressure sensor monitors the supply pressure to the tool. The tool has a second sensor which monitors strains or loads associated with a rivet set event. A processor evaluates outputs from the pressure sensor to apply a scaling factor to the output of the second sensor which is a function of the output of the pressure sensor. This modified data is analyzed to determine if the rivet set is acceptable.

  • Patent number: 6962068
    Abstract: A system is disclosed for installing an insert within an aperture in a workpiece, the workpiece having a first side and a second side. The insert is the type in which a portion of the insert plastically deforms on the second side of the workpiece upon application of a linear force provided by a tool, thereby preventing withdrawal of the insert from the aperture. The insert comprises a sleeve member and an integral flange, where the flange has a larger diameter than the aperture. The disclosed installation system performs two actions. It causes the expansion of the sleeve and it also causes the flange of the insert to be fused or welded to the first side of the workpiece. The welded connection between the insert and the workpiece prevents any rotation or spinning of the insert within the workpiece, and increases the integrity of the insert-fastener connection.
