Title (EN) VIBRATORY MACHINING DEVICE
(FR) DISPOSITIF D'USINAGE VIBRATOIRE
Abstract:
(EN) The invention relates to a machining device comprising a supporting structure, a transmission shaft (3) and a drive mechanism (1) comprising a first meshing member (13) able to drive the rotation of said shaft about the axis (A) thereof, a second meshing member (17) in a helicoidal connection with said shaft in order to drive the translational movement of said shaft along the axis thereof in a feed movement, dependent on the relative rotational velocity of said first and second meshing members, and means for generating axial oscillations. According to the invention, said second meshing member (17) is translationally mobile with respect to said supporting structure along the axis (A), said means of generating axial oscillations comprising an electromechanical actuator (20) mounted in a fixed frame of reference connected with said supporting structure, able to be coupled axially to said second meshing member (17) to cause it to oscillate translationally so as to superpose an axial oscillation component on said feed movement.
(FR) L'invention concerne un dispositif d'usinage comprenant un bâti, un arbre de transmission (3) et un mécanisme d'entraînement (1) comprenant un premier organe d'engrenage (13) apte à entraîner en rotation ledit arbre autour de son axe (A), un deuxième organe d'engrenage (17) en liaison hélicoïdale avec ledit arbre pour entraîner en translation ledit arbre le long de son axe selon un mouvement d'avance, en fonction de la vitesse relative de rotation desdits premier et deuxième organes d'engrenage, et des moyens de génération d'oscillations axiales. Selon l'invention, ledit deuxième organe d'engrenage (17) est mobile en translation par rapport audit bâti le long de l'axe (A), lesdits moyens de génération d'oscillation axiales comprenant un actionneur électromécanique (20) monté en repère fixe, lié audit bâti, apte à être couplé axialement audit deuxième organe d'engrenage (17) pour le faire osciller en translation, de manière à superposer une composante d'oscillation axiale audit mouvement d'avance.
