    摘要： 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.

    摘要： A rivet setting tool is provided including a pulling head and a jaw case connected to the pulling head such that the jaw case is driven by the pulling head to engage a rivet mandrel. Air is supplied to the pulling head to return the pulling head to its original position after a rivet has been set. A remote intensifier is provided including an air piston disposed in a piston chamber and a rod connected to the air piston and extending into a ram housing which is connected to a hydraulic passage which is connected to the pulling head. A first supply of pressurized gas communicates with a first end of the piston chamber and a second supply of pressurized gas communicates with a second end of the piston chamber for rapidly returning the air piston to the retracted position in combination with the air pressure applied to the pulling head. The second end of the piston chamber is vented to prevent to much pressure build up pushing the piston to the retracted position.

    摘要： A blind rivet set verification system for setting a blind rivet assessing the acceptability of the rivet set. The system includes a remote intensified rivet setting tool and computer hardware and software. The tool comprises a displacement transducer that produces a displacement signal and a pressure transducer that produces a pressure signal. The transducers are connected to the computer which receives the distinct signals. These signals are interpreted to plot a displacement-versus pressure waveform and to determine the velocity of the movement of an air piston that responds to the rivet set by hydraulic pressure. Using the combined date of the velocity waveform and the displacement-versus pressure waveform, the breakload is identified and compared against predetermined ideal data to assess the acceptability of the set. The displacement reading at break is corrected for jaw slippage and offset of the air piston.

    摘要： A rivet tool is mounted on a bracket which can be moved vertically up and down suitable guides. To counterbalance the system an air cylinder supports the bracket and a precision pressure regulator responds very rapidly to continuously maintain a selected pressure in the cylinder. The tool will accordingly be maintained in a perfectly counterbalanced condition continuously.
