Abstract: A device for setting a temporary fastener. The temporary fastener includes a body with an expandable/retractable end and a rotary element capable of being driven in rotation so as to cause the expandable/retractable end to expand/retract. The device includes a support module that is able to house a temporary fastener and has a holder for holding the temporary fastening inside the module. The holder is movable between at least: a locking position in which the holder is deployed inside the module so as to cooperate with a temporary fastener placed in the module in order to prevent it from moving in translation inside the module, and a rest position in which the holder is retracted so as to allow a temporary fastener to pass through the module.

Abstract: A coating device for coating a fastener with a coating material. The device includes: a distribution device for distributing the coating material, including at least one distribution nozzle; a holder for holding the fastener; a drive for causing relative movement of the fastener and of the distribution nozzle relative to one another; a controller for controlling the distribution device and able to synchronize the operation thereof in order to apply at least one line of coating material on the fastener.

Abstract: A multi-task device includes an element for securing the device to a motorized handler; an element for securing the device to a structure that is to be worked; at least two functional modules, each including at least one mobile member able to allow a given task to be accomplished; and a single drive and control assembly for driving and controlling the functional modules. The drive and control assembly includes: a single drive spindle; a drive capable of driving the movement of the spindle; a measurement element measuring at least one physical parameter indicative of at least one characteristic of operation of the functional modules; and a controller controlling the drive and the measurement element. The device further includes a coupling gear able to connect the single drive spindle, for the purposes of transmitting movement, alternatively to the at least one mobile member of the functional modules.

Abstract: A multi-task device includes at least: a rivet support module able to contain a rivet and/or a temporary fastener support module able to contain a temporary fastener; a device for introducing a rivet or temporary fastener into the modules at at least one loading station; and a device for moving the at least one module to a work station for setting a rivet or temporary fastener in a hole provided in a structure to be worked on. The multi-task device includes a device for checking compliance of the rivet or temporary fastener depending on at least one predetermined compliance criterion, and a device for discharging, to a disposal zone, a rivet or temporary fastener identified as non-compliant by the device for checking.

Abstract: The safety valve comprises a body and an obturator movable in the body between a closed position (FIG. 2) and an open position (FIG. 3). It also comprises means for displacing the obturator in order to displace it towards its closed position when the pressure of the fluid is lower than a threshold value, and the displacement means comprise: a piston for driving the obturator towards its open position, the piston being in contact with the pressurised fluid when the obturator is in the open position, and means for returning the obturator towards its closed position. Application, for example, to pneumatic machining machines.

Abstract: A pneumatic processing machine includes a pneumatic motor, a circuit for connecting the motor to a source of compressed air, a tool holder spindle, and a drive mechanism. The mechanism includes a selection element which can be moved to select a first method of driving the spindle and a second method of driving the spindle. A device for controlling the operation of the machine controls the carrying-out of a driving cycle which includes at least one phase for driving the spindle according to the first driving method, then a phase for driving the spindle according to the second driving method, then the stopping of the supply of air to the motor. A supply valve of the circuit is controlled mechanically by the selection element to interrupt the supply of compressed air to the motor at the end of the driving cycle.
