Title (EN) DEVICE FOR DAMPING THE VIBRATIONS OF A SHARPENING MACHINE TOOL
(FR) DISPOSITIF POUR AMORTIR LES VIBRATIONS D"UNE MACHINE-OUTIL A AFFUTER
Abstract: front page image
(EN)Machine tool for sharpening the edges of rotating cutting tools, for lathe tools or the like: it comprises a fixing spindle (22) rotating and carrying the sharpening tool, and a divider mechanism (25) indexing automatically this spindle each time at least by a cutting division of the tool. This divider mechanism (25) is arranged on a first frame displaceable longitudinally and/or pivoting whereas the sharpening disc is mounted on a second frame: at least the frame carrying the fixing spindle is connected through a mechanism free of clearance to a step by step electric motor. To reduce and compensate the impulse due to the drive of the step by step motor, an inertia mass (20) relative to the resonance torque frequency of the drive is coupled to a drive shaft (24, 15) of the divider mechanism and/or of at least one frame, by means of a coupling allowing under the action of the kinetic movement, a relatively reduced torque of the inertia mass relative to the drive shaft.
(FR)On presente une machine-outil pour affuter les tranchants des outils de coupe tournants, pour des outils de tournage ou similaires; elle comporte une broche de fixation (22) mobile en rotation portant l"outil d"affutage, et un mecanisme diviseur (25) indexant automatiquement cette broche chaque fois au moyen d"une division de coupe de l"outil. Ce mecanisme diviseur (25) est dispose sur un premier bati deplacable longitudinalement et/ou pivotant alors que le disque d"affutage repose sur un deuxieme bati; au moins le bati portant la b roche de fixation est relie, par l"intermediaire d"un mecanisme sans jeu, a un moteur electrique pas a pas. Pour attenuer et compenser l"impulsion provenant de la transmission du moteur pas a pas, une masse d"inertie (20) relative a la frequence de resonance de torsion de l"entrainement est couplee a un arbre de transmission (24, 15) du mecanisme diviseur et/ou d"au moins un bati, par l"intermediaire d"un accouplement permettant, sous l"action du mouvement cinetique, une torsion relativement attenuee de la masse d"inertie relative a l"arbre de transmission.
