Abstract
A tool element (10) provided with a cutting insert (11) is readily attachable to and detachable from an elongated holder body (12), which is secured to a machining tool. The tool element (10) is clamped against the holder body (12) by means of a bar (19) which is longitudinally movable in the holder body. In order to prevent the cutting forces from causing a relative movement between the tool element (10) and the holder body (12) projections (23, 24) on the tool element (10) are forced against opposed abutting surfaces (16, 17) on the holder body (12) by means of complementary cam surfaces on an enlarged portion (21) on the bar and on the projections (23, 24) upon a clamping movement of the bar (19).
Claims10
A cutting tool comprising an elongated holder body, and a bar movable in the holder body for clamping a tool element against the holder body, said tool element being provided with a cutting means, characterized in that the tool element is provided with a groove, the opening of said groove facing the bar, said tool element having projections at said opening into said groove from both sides thereof so as to provide the opening with a restricted cross section area, and that the bar is provided with an enlarged portion adjacent to the tool element, said groove being adapted to receive said enlarged portion, said enlarged portion and projections having complementary cam surfaces so that when pulling by means of the bar the tool element against at least one end surface on the holder body the projections are caused to expand in opposite directions, thereby forcing the projections against opposed abutting surfaces on the holder body.
