Abstract

A self-centering clamping device for a blade includes a mount having a root reception orifice which has a contour adapted to a root of the blade. The root reception orifice extends in the vertical direction and has a vertically running groove for receiving at least part of the root of the blade. A rotatable roller is arranged in a lower region of the root reception orifice and forms a stop for the root of the blade, a contact region of the roller for the root lying in an angular range larger than 0° and smaller than 90°, and the angular range being oriented upward and into the root reception orifice.

Claims

exact text as granted — not AI-modified
1 - 11 . (canceled) 
     
     
         12 . A self-centering clamping device for a blade, comprising:
 a mount having a root reception orifice which has a contour adapted to a root of the blade,   wherein the root reception orifice extends in the vertical direction and has a vertically running groove for receiving at least part of the root of the blade,   wherein a rotatable roller is arranged in a lower region of the root reception orifice and forms a stop for the root of the blade, a contact region of the roller for the root lying in an angular range larger than 0° and smaller than 90°, and the angular range being oriented upward and into the root reception orifice.   
     
     
         13 . The self-centering clamping device as claimed in  claim 12 , wherein the roller has a rolling bearing. 
     
     
         14 . The self-centering clamping device as claimed in  claim 12 , wherein an axis of rotation of the roller is at an angle with respect to the horizontal. 
     
     
         15 . The self-centering clamping device as claimed in  claim 12 , wherein the mount comprises a grooved block. 
     
     
         16 . The self-centering clamping device as claimed in  claim 12 , wherein the roller is arranged opposite a vertically running groove orifice. 
     
     
         17 . The self-centering clamping device as claimed in  claim 16 , wherein a sliding roller is arranged above the roller and opposite the groove orifice. 
     
     
         18 . The self-centering clamping device as claimed in  claim 17 , wherein a plurality of sliding rollers are arranged one above the other. 
     
     
         19 . The self-centering clamping device as claimed in  claim 12 , wherein two rollers are provided. 
     
     
         20 . The self-centering clamping device as claimed in  claim 16 , wherein an eccentric for clamping the root is arranged opposite the groove orifice. 
     
     
         21 . The self-centering clamping device as claimed in  claim 12 , wherein the root reception orifice is in the form of a blade fastening groove. 
     
     
         22 . A measuring device for a blade, comprising:
 a self-centering clamping device as claimed in  claim 12 .
