Abstract
The present disclosure relates to a device for fastening a lockbolt, the device comprising: a lockbolt gun including a body unit having a grip therein for pulling the lockbolt and a gripping unit protruding from a lower portion of the body unit and having an operation switch installed on the outside, wherein a hydraulic supply flow path for supplying hydraulic pressure for driving the grip, a hydraulic discharge flow path for discharging hydraulic pressure supplied to the grip, and an air supply flow path for supplying pneumatic pressure to the operation switch are installed in the gripping unit, and a discharge hole is formed outside the gripping unit to discharge air from the air supply flow path when the operation switch is operated; a driving force supply unit having a hydraulic supply pump that supplies hydraulic pressure to the hydraulic supply flow path, a hydraulic recovery pump that recovers hydraulic pressure discharged from the hydraulic discharge flow path, and an oil tank that supplies oil to the hydraulic supply pump and recovers oil from the hydraulic recovery pump; an operating unit having a first solenoid valve connected to the hydraulic supply pump, the hydraulic recovery pump, and the air supply flow path, an air supply unit that supplies air to the first solenoid valve, and an air pressure regulator installed between the first solenoid valve and the air supply unit to regulate pneumatic pressure supplied to the first solenoid valve; a housing accommodating the driving force supply unit and the operating unit; and a control unit for controlling the hydraulic supply pump and the hydraulic recovery pump to operate so that the pneumatic pressure is supplied from the first solenoid valve to the hydraulic supply pump and the hydraulic recovery pump when an operating signal is inputted from the operation switch.
