Patent ID: 8578622

Claim:
An alignment device for aligned and detachable securing of at least one functional component ( 10 ), in particular in the form of a tool holder, on another functional component ( 12 ), in particular in the form of a tool disk, around at least one alignment axis ( 14 ), wherein the two functional components ( 10 , 12 ) each have at least one contact surface ( 16 , 18 ) for mutual contact with one another, characterized in that both one and also the other functional component ( 10 , 12 ) have at least one alignment part ( 22 , 24 ); that the respective alignment part ( 22 ) of one functional component ( 10 ) is part of an alignment body ( 30 ) and forms an alignment surface ( 26 ) which can be moved into at least partial contact with one positioning surface ( 28 ) of the assignable alignment part ( 24 ) of the other functional component ( 12 ) with a definable alignment force; and that the definable alignment force is formed by a preload which is produced by an elastic deflection of the part ( 36 ) which forms the respective alignment surface ( 26 ), which deflection takes place when the functional components ( 10 , 12 ) are secured on one another, relative to the other part ( 34 ) of the alignment body ( 30 ).
