Abstract
Official abstract text for this publication.
A tool clamping fixture includes at least one clamping unit, at least one operating unit, and at least one return damping unit. The at least one clamping unit is configured to fixedly clamp a machining tool in an axial direction. The at least one operating unit is configured to actuate the at least one clamping unit. The at least one return damping unit is at least configured to damp a return motion of the at least one operating unit. The at least one return damping unit is also configured to generate friction torques of different magnitudes in opposite directions of motion of the at least one operating unit.
First claim
Opening claim text (preview).
The invention claimed is: 1. A tool clamping fixture, comprising: at least one clamping unit configured to clamp a machining tool in an axial direction; at least one control unit configured to actuate the at least one clamping unit; and at least one return damping unit configured at least to damp a return motion of the at least one control unit, wherein the at least one return damping unit is configured to generate friction torques of different magnitude in oppositely directed motional directions of the at least one control unit. 2. The tool clamping fixture as claimed in claim 1 , wherein the at least one return damping unit has at least one return damping element disposed on a transmission element of the at least one control unit. 3. The tool clamping fixture as claimed in claim 2 , wherein the at least one return damping element is disposed along a peripheral direction on the transmission element of the at least one control unit. 4. The tool clamping fixture as claimed in claim 2 , wherein the at least one return damping element is configured as a leg spring. 5. The tool clamping fixture as claimed in claim 2 , wherein the at least one return damping element is pivotably mounted. 6. The tool clamping fixture as claimed in claim 5 , wherein the at least one return damping unit has at least one spring element configured to subject the at least one return damping element to a spring force in at least one direction. 7. The tool clamping fixture as claimed in claim 5 , wherein the at least one return damping unit has at least one stop element configured to limit a motion of the at least one return damping element in at least one direction. 8. The tool clamping fixture as claimed in claim 2 , wherein the at least one return damping element is configured as a freewheeling roller bearing configured to prevent a rotary motion at least in one motional direction. 9. A portable machine tool, comprising: at least one tool clamping fixture, including: at least one clamping unit configured to clamp a machining tool in an axial direction; at least one control unit configured to actuate the at least one clamping unit; and at least one return damping unit configured at least to damp a return motion of the at least one control unit, wherein the at least one return damping unit is configured to generate friction torques of different magnitude in oppositely directed motional directions of the at least one control unit.
