Abstract:For the automatic installation requirements of spacecraft fasteners, a set of fastener automatic installation system used by robot was developed. This paper introduces the composition and design principle of automatic installation robot for faster. The industrial robot was used to drive the fastener to the installation position, the screw is picked and automatically blow to the installation position by blowing air, a pneumatic sliding table is used to press the screw at the installation position, an electric torque gun is used to tighten the screw, automatic installation experiment was carried out. The test results show that the tightening torque was controlled within the range and meets the accuracy requirements for spacecraft fastener installation.
