Patent number: 11717941Abstract: A tool or workpiece holder with a receiving body and a clamping device for clamping a tool or a workpiece in a receiving opening of the receiving body. The clamping device comprises a first clamping element, which can be moved in a receiving portion of the receiving body at right angles to a central axis of the receiving opening, and a second clamping element, which can be moved relative to the first clamping element at right angles to the central axis of the receiving opening by means of an actuating element. The second clamping element has conical bottom clamping surfaces on the two clamping elements for inserting the tool or workpiece into the receiving opening. An ejecting mechanism is disposed on the first clamping element for ejecting the tool or workpiece from the receiving opening when the clamping elements are moved into a disengaged position.Type: GrantFiled: August 2, 2021Date of Patent: August 8, 2023Assignee: Ott-Jakob Spanntechnik GmbHInventors: Josef Greif, Wolfgang Bechteler, Conrad Rösch, Maximilian Horn

Patent number: 10646929Abstract: A clamping device for clamping a workpiece or a tool or, more specifically, a tool holding fixture in a machine part of a machine tool includes a tension rod slidably mounted within the machine part; a clamping set movable by the tension rod between clamped and released positions; a tension spring dedicated to the tension rod so as to generate the pull-in force of the clamping set; and a release mechanism, by which the clamping set can be moved against the force of the tension spring into the released position by the tension rod. To make possible effective clamping at optimum force, the tension spring is clamped between first and second rod parts of the tension rod. The second rod part can move relative to the first rod part, and, as the clamping set moves into the released position, is compressed on both ends by the release mechanism by moving the two rod parts in opposite directions.Type: GrantFiled: March 28, 2018Date of Patent: May 12, 2020Assignee: Ott-Jakob Spanntechnik GmbHInventors: Josef Greif, Peter Mohr, Conrad Rösch, Bartholomäus Reisacher

Patent number: 10124414Abstract: A clamping assembly for a clamping device for clamping of a workpiece or tool or a toolholder on machine component with a clamping cone movable axially via a tension rod and several clamping elements arranged spaced from each other in the peripheral direction on the outside of the clamping cone, which can be moved between a radially outer clamped position and a radially inner released position by axial movement of the tension rod. The clamping cone includes two parts movable opposite each other in the axial direction.Type: GrantFiled: December 6, 2016Date of Patent: November 13, 2018Assignee: OTT-JAKOB SPANNTECHNIK GMBHInventors: Josef Greif, Conrad Rösch, Bartholomäus Reisacher, Jr.

Patent number: 7473060Abstract: The subject matter of the present invention relates to a clamping device for clamping a tool or a tool holder (2) in a machine spindle (1), comprising a drawbar (6) that can axially move back and forth between a clamping position and a release position, a clamping spring (18) for actuating the drawbar (6) in the direction of the clamping position, a minimum of one sensor (20) for monitoring the clamping force, and a clamping cone (8) having a plurality of clamping elements (9) that rest against its outside surface, which clamping elements, via the axial movement of the clamping cone (8) by means of the drawbar (6), can be moved back and forth between a clamping position in which the tool or tool holder (2) is retained and a release position in which the tool or tool holder (2) is released.Type: GrantFiled: January 22, 2008Date of Patent: January 6, 2009Assignee: Ott-Jakob Spanntechnik GmbHInventors: Peter Mohr, Wolfgang Bechteler, Stephan Gast, Josef Greif, Conrad Rösch
