Abstract: front page image
(EN)A boring tool (8) is interchangeable on the spindle of a boring unit. The tool (8) is carried by a tool holder (6) which is orientable about an axis offset transversally with respect to the axis of the spindle. The tool holder (6) is connected to a support-ing arm (10), which bears on a wedge shaped surface (12) slightly inclined of an adjustable device (13), axially movable in the spindle (1) by means of a rod (15). By axially displacing the rod (15), the boring tool (8) is radially adjustable. The tool (8) is extensible in the tool carrier (6) by means of balls (19) tensioning the jaws (18, 19, 20); the balls (19) are contained in an axially displaceable cage (18). At the end of the axial motion of the rod (15), the latter moves the resilient cage (18), held in its tensioning position, and releases the jaws of the boring tool (8).
(FR)On presente un outil d"alesage (8) interchangeable sur la broche d"une unite d"alesage. L"outil (8) est porte par un porte-outil (6), qui est orientable autour d"un axe decentre transversalement par rapport a l"axe de la broche. Le porte-outil (6) est relie a un bras-support (10), qui s"appuie sur une surface en forme de coin (12) legerement inclinee d"un dispositif reglable (13), qui est deplacable axialement dans la broche (1) au moyen d"une bielle (15). Par un deplacement axial de la bielle (15), l"outil d"alesage (8) est reglable radialement. L"outil (8) est extensible dans le porte-outil (6) au moyen de billes (19) mettant en tension les machoires (18, 19, 20); les billes (19) sont contenues dans une cage (18) deplacable axialement. A la fin du mouvement axial de la bielle (15), celle-ci deplace la cage (18) elastique, tenue dans sa position de tension, et libere les machoires de l"outil d"alesage (8).
