METHOD OF RIVETING OF CURVILINEAR PANELS AT DRILLING-RIVETING MACHINE Russian patent published in 2015 - IPC B21J15/44 G05B19/18 

FIELD: machine building.

SUBSTANCE: surface of curvilinear panel is levelled up in the riveting zones by its orientation at right angle to axis of the force head of the drilling-riveting machine. At that three levelling sensors are used to measure distance from them to the panel surface. The sensors are located on casing of the power head with making of the equilateral triangle by their parallel axis upon crossing the perpendicular plane. At middle of the altitude of the triangle the plane crosses the axis of the power head creating value that is parameter determining distance between levelling sensors. During the sensors installation this value is set depending on tolerance for misalignment of the rivet axis relatively to the panel surface. The panel orientation is made until equality of the distances to it measured by the sensors. Liner movement of the drilling-riveting machine over the riveting zones of the panel is performed to value determined as per the specified equation.

EFFECT: higher accuracy of riveting.
