The invention relates to a vibrating rivet tool (1, 15) for pressing and fixing rivets (3) in component holes (7) in component (8) of aircraft. The vibrating rivet tool (1, 15) comprises a rivet receptacle (2, 14) and a drive unit (4, 16) for producing a high static pressing force (5). According to the invention, the static pressing force (5) is superimposed by a mechanical vibration (11, 19), of which the amplitude acts substantially in the direction of a longitudinal axis (6) of the rivet. As a result, the force necessary to press and fix the rivet (3) in a component hole (7) is reduced in such a way that the overall size and mass of the vibrating rivet tool (1, 15) according to the invention are smaller/ lower in comparison with conventional rivet tools. Due to the small overall size and low weight, the vibrating rivet tool (1, 15) can more easily be integrated in automated riveting processes.

L'invention concerne un outil de rivetage par vibration (1, 15) pour appuyer sur des rivets (3) et les fixer dans des trous de composant (7) dans un composant (8) d'avion. L'outil de rivetage par vibration (1, 15) comprend un récipient de rivet (2, 14) et une unité d'entraînement (4, 16) pour produire une force de pression statique élevée (5). Selon l'invention, la force de pression statique (5) est superposée à une vibration mécanique (11, 19) dont l'amplitude agit sensiblement dans la direction d'un axe longitudinal (6) du rivet. Par suite, la force nécessaire pour appuyer sur le rivet (3) et le fixer le rivet dans un trou de composant (7) est réduite d'une manière telle que la taille et la masse globales de l'outil de rivetage par vibration (1, 15) selon l'invention sont inférieures aux outils de rivetage classiques. La petite taille et le faible poids de l'outil de rivetage par vibration (1, 15) permet son intégration facile dans des procédés de rivetage automatisés.
