Abstract:
A coupling for coupling hollow parallelepiped-shaped receiving components for chucking workpieces in defined and reproducible positions, each receiving component having fitting bores and transverse bores having equal diameters and arranged in regular coordinate spacings, the coupling comprising a coupling member having a projection, the projection being adapted to be insertable with precise fit into a hollow space of an end face of a receiving component to be connected, the projection having a plurality of hook elements, the hook elements being pivotable so as to be adapted to move the hook elements into a positively locking engagement with a wall surface of an adjacent fitting bore or transverse bore, further comprising worm gears rotatable mounted in the projection, each worm gear being in engagement with one of the hook elements for pivoting the hook elements, wherein each worm gear is mounted so as to be adapted to be accessible through the fitting bore or transverse bore against whose wall surface the engagement surface of the corresponding hook element is adapted to come into contact.
