Quick Clamping Device

Abstract

A quick clamping device for a machine tool, in particular for a hand-held machine tool, includes at least one clamping device that is moveably mounted in particular on an output spindle of the machine tool that can be rotationally driven about an output shaft of the machine tool, at least for axially securing a tool device, in particular an insert tool, on the output spindle of the machine tool. The quick clamping device includes at least one movement securing unit having at least one movement securing element arranged in particular on the clamping device, which is provided for a movement of the tool device, in particular in a rotary drive position, and/or for securing the tool device.

1 . A quick-clamping system for a power tool comprising:
 at least one clamping device which is mounted in a movable manner on an output spindle of the power tool, said output spindle configured to be driven in rotation about an output axis of the power tool, the at least one clamping device configured to axially securing a tool device on the output spindle of the power tool; and   at least one movement-securing unit, which has at least one movement-securing element arrange on the clamping device, the at least one movement-securing element configured to move and/or secure the tool device.   
     
     
         2 . The quick-clamping system as claimed in  claim 1 , wherein the at least one movement-securing element includes a holder and is configured such that, in at least one state, the at least one movement-securing element at least partially accommodates a further movement-securing element of the movement-securing unit, said further movement-securing element engaging through the tool device and including an extension. 
     
     
         3 . The quick-clamping system at least as claimed in  claim 1 , wherein the at least one movement-securing unit is configured to convert a relative movement of the clamping device into a relative movement of the tool device. 
     
     
         4 . The quick-clamping system as claimed in  claim 3 , wherein the at least one movement-securing element includes an oblique surface, which is configured, based on a movement of the at least one clamping device, to generate a force component which acts on the tool device along a circumferential direction. 
     
     
         5 . The quick-clamping system as claimed in  claim 3 , wherein the at least one movement-securing unit includes at least one further movement-securing element arranged on the output spindle, the at least one further movement-securing element including a conical extension configured to interact with a fixing aperture of the tool device. 
     
     
         6 . The quick-clamping system as claimed in  claim 1 , wherein the at least one movement-securing unit includes at least one pre-positioning element configured to pre-position the tool device prior to the tool device being secured by the at least one clamping device. 
     
     
         7 . The quick-clamping system as claimed in  claim 6 , wherein the at least one pre-positioning element includes a magnet. 
     
     
         8 . The quick-clamping system as claimed in  claim 1 , wherein the at least one movement-securing unit has at least one linear abutment element onto which the tool device is pushed by the at least one clamping device. 
     
     
         9 . The quick-clamping system as claimed in  claim 8 , wherein the linear abutment element includes a circular ring. 
     
     
         10 . A power tool comprising:
 an output spindle configured to be driven in rotation about an output axis of the power tool; and   at least one quick-clamping system comprising:
 at least one clamping device which is mounted in a movable manner on the output spindle, the at least one clamping device configured to axially securing a tool device on the output spindle of the power tool; and 
 at least one movement-securing unit, which has at least one movement-securing element arranged on the clamping device, the at least one movement-securing element configured to move and/or secure the tool device. 
   
     
     
         11 . The quick-clamping system as claimed in  claim 1 , wherein the quick-clamping system is arranged on a hand-held power tool. 
     
     
         12 . The quick-clamping system as claimed in  claim 1 , wherein the at least one clamping device is configured to axially secure an insertion tool on the output spindle. 
     
     
         13 . The quick-clamping system as claimed in  claim 1 , wherein the at least one movement-securing element is configured to move the tool device into a rotary carry-along position. 
     
     
         14 . The quick-clamping system as claimed in  claim 2 , wherein the extension of the further movement-securing element is configured as an axially-extending extension. 
     
     
         15 . The power tool as claimed in  claim 10 , wherein the power tool is a hand-held power tool.
