Abstract

The present invention discloses a riveting robot, comprising: a robot part provided on a chassis, and detachably coupled with a riveting tool part through a hydraulically quick change disk; a visual position identification part provided on a side of the hydraulically quick change disk and secured on the sixth axis of the front end of the robot part; an automatic rivet feeding part provided on a mounting baseplate which is secured on a chassis through a two-stage vibration damping structure; a riveter tailing material collection part used for collecting tailing materials produced during riveting; a riveting quality judgment part used for collecting riveting data, and processing and generating a riveting curve to realize judgment of the riveting quality. A riveting robot system provided in the present invention can realize unmanned quick mounting of a pulling rivet at a specific riveting position; a vibration damping structure effectively isolates interference of riveting operation of a robot from a vibration source; radial and axial damping mechanisms can absorb axial and radial impact energies during the process of rivet pulling and mounting, ensuring that the operating accuracy of the riveting robot system and service life of the riveting robot mechanism.
