Device for repeatably setting the spatial position of a first object in relation to other objects with extreme accuracy

摘要

The device for reproducible coupling of two objects, specifically of a workpiece (WS) or a tool with a machine tool, attaches the workpiece (WS) or the tool for precise positioning to one of two coupling parts (1,2) in a position precisely defined in reference to a reference system of all machine tools through which the workpiece must travel. The attachment surface of one coupling P(2) has rigid profile pieces (4,1). These can be engaged with the attachment surface of the other coupling part (1) without relative motion of the two coupling parts (1,2), with the help of an appropriate number of suitable and at least partly elastically deformable transfer elements (3,3') for power transmission. The elastically deformable transfer elements (3,3') are integral parts of the latter coupling part (1) (FIGS. 1 and 2).
