摘要:
A nut (6) is inserted into a screw attachment (1), said nut accommodating the head of a fastening element. The nut (6) is made of two cheeks (4, 5) which engage into a sleeve-like holder (3) with torsional rigidity. The cheeks can be moved in axial direction in relation to the holder (3). In one of the end positions, the cheeks (4, 5) can be pressed apart for insertion of the head of a fastening element. By exerting an axial force in the direction of the arrow (23), the cheeks (4, 5) are pressed into the holder (3), whereby the cheeks are forced against each other in a radial direction as a result of their sharp corner contact surfaces (12, 13), so that the inserted head of a fastening element is firmly retained.

Die Erfindung betrifft einen Werkzeughalter (10), mit einer mit einem Schaft (14) eines Werkzeugs (12) verspannbaren Spannzange (26), mit einer Auszugssicherung zur Sicherung des Werkzeugs (12) gegen ein Ausziehen aus der Spannzange (26), wobei die Auszugssicherung (36) ein Sicherungselement (38) zur Übertragung einer auf das Werkzeug (12) wirkenden Auszugskraft auf die Spannzange (26) umfasst, wobei das Sicherungselement (38) relativ zu der Spannzange (26) bewegbar gelagert ist, und wobei das Sicherungselement (38) keilförmig ausgebildet ist und Kraftübertragungsflächen (48, 50) aufweist, mittels welchen das Sicherungselement (38) in seiner Eingriffslage mit dem Werkzeug (12) mit diesem und mit der Spannzange (26) selbsthemmend verspannbar oder verspannt ist.
摘要:
The invention provides a clamping system (1) for a rotary tool (70), for example a milling cutter or drill. The clamping system (1) consists of a base (10), a collet chuck (30) and a clamping nut (50), said clamping nut (50) force-locking the rotary tool (70) within the base (10) with the collet chuck (30). In order to avoid a relative rotation of the base (10) and the collet chuck (30), the clamping system (1) has a positive anti-twist protection which blocks rotation of the collet chuck (30) with respect to the base (10).
