Alignment device
The invention relates to an alignment device for the aligned and detachable fixing of at least one functional component ( 10 ), in particular in the form of a tool holder, to a further 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 ) have in each case at least one contact face ( 16, 18 ) for mutual contact with each other. Said alignment device is characterized in that both the one and the further functional component ( 10, 12 ) have at least one alignment part ( 22, 24 ), in that the respective alignment part ( 22 ) of the one functional component ( 10 ) is a constituent part of an alignment element ( 30 ) and forms an alignment face ( 26 ), which can be brought into at least partial contact with a positioning face ( 28 ) of the associated alignment part ( 24 ) of the further functional component ( 12 ) with a predefinable alignment force, and in that the predefinable alignment force is formed by the preload which is produced by a resilient deflection of the part ( 36 ) forming the respective alignment face ( 26 ) relative to the remaining part ( 34 ) of the alignment element ( 30 ), taking place as the functional components ( 10, 12 ) are fixed to each other.

3. The alignment device according to claim 2 , characterized in that the strip-shaped alignment body ( 30 ) is slotted with the formation of two interconnected strip bodies ( 34 , 36 ) and that one strip body ( 36 ), which has the respective alignment part ( 22 ), can be deflected against the elastic force relative to the other strip body ( 34 ), which can be connected to one functional component ( 10 ) by means of a connecting device ( 32 ).
4. The alignment device according to claim 1 , characterized in that at least two pairs, but preferably four pairs of alignment parts ( 22 , 24 ) are arranged diametrically to one alignment axis ( 14 ).
5. The alignment device according to claim 1 , characterized in that the respective alignment part ( 24 ) of the other functional component ( 12 ) with its positioning surface ( 28 ) is preferably an integral component of this functional component ( 12 ).
6. The alignment device according to claim 5 , characterized in that the respective positioning surface ( 28 ) located in the direction of a depression ( 48 ) extends between two contact surfaces ( 18 ) of the other functional component ( 12 ).
7. The alignment device according to claim 1 , characterized in that the alignment surface ( 26 ) and the positioning surface ( 28 ) of one pair of alignment parts ( 22 , 24 ) are made as oblique surfaces ( 52 , 54 ) of the same slope or as surfaces which are arched with same curvature.
8. The alignment device according to claim 1 , characterized in that one functional component ( 10 ) with a retaining part ( 56 ), extending through the contact surface ( 18 ) of the other functional component ( 12 ), engages the latter and in its functional position is secured by means of a detachable locking device such that the alignment parts ( 22 , 24 ), which interact in pairs, are held on one another under a force which produces the elastic deflection of the alignment surfaces ( 26 ) and the preload between the latter and the positioning surfaces ( 28 ).
9. The alignment device according to claim 8 , characterized in that the preload is chosen so that the alignment parts ( 22 ), which are located in pairs on one strip body ( 36 ), with their alignment surfaces ( 26 ) relative to the assigned positioning surfaces ( 28 ) of the alignment parts ( 24 ), undergo a tilt which adjusts this strip body ( 36 ) to the other strip body ( 34 ) in an oblique position.
