Abstract
In known cutter heads, the centrifugal forces occurring at high rotational speeds may cause the occurrence of dilatations permitting the cutting edges of the cutting tools to shift from their adjusted positions. An object of the invention is the provision of a cutter head capable of being accurately and reliably adjusted for operation also at high rotational speeds. According to the invention, a clamping wedge 13 is provided with a skewed clamping surface 21b adapted to cooperate with a contact surface 21a of a cutter blade carrier 2 for clamping it in a groove 20 of a mounting body 1. The invention also proposes the provision of a prism wedge clamping system 10 for supporting the cutter head carrier 2 in the radial direction relative to the mounting body 1.
Claims16
A cutter head having a substantially cylindrical mounting body having its periphery formed with a plurality of grooves opening at its end face and part of its peripheral surface and containing each a cutter blade carrier carrying a cutter blade, an axially displaceable radial adjustment wedge disposed behind said cutter blade carrier as viewed in the circumferential direction of rotation with its active surfaces contacting said cutter blade carrier and said mounting body, an axial adjustment wedge disposed axially behind said cutter blade carrier for radial displacement by means of a differential screw, and a radially adjustable clamping wedge disposed in front of said cutter blade carrier as viewed in the circumferential direction of rotation, characterized in that said clamping wedge (13) engages said cutter blade carrier (2) via a pair of inwardly inclined slope contact surfaces (21A, 21B), whereas said cutter blade carrier (2) is supported at the bottom side of the groove (20) by means of a pre-tension multiprism wedge clamp assembly (10) with the cutter blade (4) being supported on said cutter blade carrier (2) by means of a rotatable cutter blade cage (3).
