Abstract

Gemäß der Erfindung besitzt bei einer Spannvorrichtung zum Festspannen eines Werkzeugs (6) an einer Bearbei­ tungsmaschine mit einem aus einem Spannzylinder (2) unter Hydraulikdruck ausfahrbaren Spannkolben (1), der an sei­ nem freien Ende eine Kolbennase (10) mit einer Keilfläche (7) aufweist, diese Keilfläche (7) eine derart an einen mit ihr zusammenwirkenden Oberflächenabschnitt (14) des festzu­ spannenden Werkzeugs (6) angepaßte Form, daß zwischen der Keilfläche (7) und diesem Oberflächenabschnitt (14) Keilselbsthemmung auftritt. According to the invention in a tensioning device for clamping a tool (6) on a machining processing machine with one from a clamping cylinder (2) under Hydraulic pressure extendable tensioning piston (1) on a free end of a piston nose (10) with a wedge surface (7) has, this wedge surface (7) one to one with it cooperating surface portion (14) of the to exciting tool (6) adapted shape that between the wedge surface (7) and this surface section (14) Wedge self-locking occurs.

Auf diese Weise ergibt sich eine mechanische Verriege­ lung zwischen dem festzuspannenden Werkzeug (6) und der Spannvorrichtung, und diese Verriegelung bleibt auch ohne hydraulischen Spanndruck wirksam und hält das Werkzeug (6) sicher auf seiner Unterlage an der Bearbeitungsmaschine fest. This results in mechanical locking tion between the tool to be clamped (6) and the Clamping device, and this locking remains without hydraulic clamping pressure is effective and holds the tool (6) securely on its base on the processing machine firmly.

Bevorzugt ist die Kolbennase (10) des Spannkolbens (1) zwecks Anpassung an unterschiedliche Werkzeugformen austauschbar. Die gesamte Spannvorrichtung kann als eine in eine entsprechende Aufnahme (16) an der Bearbeitungs­ maschine einführbare Einsteckpatrone ausgebildet sein. Der Weg des Spannkolbens (1) im Spannzylinder (2) und insbe­ sondere die Spannposition lassen sich mit Hilfe von Nähe­ rungsschaltern (5) elektrisch überwachen. The piston nose (10) of the tensioning piston (1) is preferred to adapt to different tool shapes interchangeable. The entire jig can be used as one in a corresponding receptacle (16) on the processing be inserted insertable cartridge. The Path of the clamping piston (1) in the clamping cylinder (2) and esp the clamping position in particular can be adjusted with the help of proximity Monitor the circuit breakers (5) electrically.
