Patent

CA 2381929

An apparatus (10) is disclosed for releasably holding a toolholder shank (30) having a lockable surface (90, 95) and a releasable surface (185) utilizing an actuating bolt (20) with an associated threaded actuating nut (75). When the actuating bolt (20) is rotated in a locking direction, the actuating nut (75) is drawn onto the bolt (20) thereby clamping against the lockable surfaces (90, 95) of the toolholder shank (30). When the actuating bolt (20) is rotated in the releasing direction, a releasing segment (170) acts upon the toolholder (25) thereby ejecting it from the tool support member (15).

L'invention concerne un appareil (10) permettant de saisir de manière réversible la queue (30) d'un porte-outil, présentant une surface de blocage (90, 95) et une surface de déblocage (185) associées à un boulon de blocage/déblocage (20) et son écrou de blocage/déblocage (75). Lorsque le boulon de blocage/déblocage (20) est tourné dans la direction de blocage, l'écrou de blocage/déblocage (75) est placé sur le boulon (20) assemblant ainsi les surfaces de blocage (90, 95) de la queue (30). Lorsque le boulon de blocage/déblocage (20) est tourné dans la direction de déblocage, un segment de déblocage (170) agit sur le porte-outil (25) le séparant ainsi de son support (15).
