<p>The proposed device for mounting cutting inserts of different dimensions or cassettes holding such inserts in a modular cutting instrument comprises a main unit (7) into a groove (6) of which are mounted the cutting inserts (8, 9) or cassettes (10) holding them on two mutually perpendicular surfaces (4, 5) with the aid of fastening screws (1) and clamp elements. One of these mutually perpendicular surfaces (5) is parallel to the front surfaces of the cutting inserts (8, 9), provided with a pliant element and an adjusting screw (16) with a conical head (17) mounted in the threaded aperture (18) of the main body (7) and designed to co-operate with the pliant element. The main body (7) is provided with an oval funnel-shaped aperture (20) which accommodates the conical head (17) of the adjusting screw (16); the fastening screws (1) likewise have conical heads (2) and the clamp elements are blocks (3) with planes designed to be contiguous with the cutting inserts (8, 9) and fitted in the groove (6) of the main body (7) of the cutting instrument so as to allow self-adjustment relative to the cutting inserts (8, 9) or cassettes (10) holding them. The main body (7) and blocks (3) have surfaces co-operating with the conical heads (2) of the fastening screws (1) and forming funnel-shaped apertures of preferably oval cross section when the unit is assembled. The planes of the blocks (3) contiguous with the cutting inserts (8, 9) or cassettes (10) holding them are provided with cylindrical recesses (15) along the height of the block (3) and the pliant element is a connecting strip (21).</p> |
