Abstract

MANDRIN OSCILLANT POUR MACHINE-OUTIL. IL COMPORTE UN ORGANE DE SERRAGE DE LA PIECE, POUVANT PIVOTER ENTRE LES BRANCHES D'UN CORPS DE MANDRIN, PERPENDICULAIREMENT A L'AXE DE LA BROCHE DE LA MACHINE. DES MOTEURS HYDRAULIQUES, MONTES SUR CES BRANCHES, COMPORTENT UN PISTON PIVOTANT EN FORME DE SECTEUR, SOLIDAIRE DU PIVOT CORRESPONDANT DE L'ORGANE DE SERRAGE, AINSI QU'UNE BUTEE LIMITANT L'AMPLITUDE DU PIVOTEMENT DE CES PISTONS. LES PIVOTS PORTENT DES DISQUES DIVISEURS A ENCOCHES PERIPHERIQUES, AVEC LESQUELS COOPERENT DES VERROUS COULISSANT SUR LES BRANCHES DU CORPS DU MANDRIN. APPLICATION NOTAMMENT AUX TOURS AUTOMATIQUES.SWINGING CHUCK FOR MACHINE-TOOL. IT INCLUDES A PART FOR CLAMPING THE PART, WHICH CAN PIVOT BETWEEN THE BRANCHES OF A CHUCK BODY, PERPENDICULARLY TO THE AXIS OF THE MACHINE SPINDLE. HYDRAULIC MOTORS MOUNTED ON THESE BRANCHES HAVE A SWIVEL PISTON IN THE FORM OF A SECTOR, SOLID WITH THE CORRESPONDING PIVOT OF THE TIGHTENING DEVICE, AS WELL AS A STOP LIMITING THE AMPLITUDE OF THE PIVOTATION OF THESE PISTONS. THE PIVOTS CARRY DIVIDING DISCS WITH PERIPHERAL NOTCHES, WITH WHICH SLIDING LOCKS COOPERATE ON THE BRANCHES OF THE CHUCK BODY. APPLICATION ESPECIALLY TO AUTOMATIC LATHES.
