CUTTER Russian patent published in 1996 - IPC

FIELD: mechanical engineering. SUBSTANCE: cutting plate with an opening is received in the socket of a holder of the cutter bounded with side and bottom bearing surfaces. The opening receives a screw for connecting the cutting plate with lining mounted on the bottom bearing surface of the socket of the holder and gripped by way of a fastening member. The fastening member is made up as a pin. The end face of the pin is provided with a trancated cone arranged eccentrically. The generatrix of the cone interacts with the generatrix of the conical opening provided in the side of the lining for interaction with bottom bearing surface of the holder socket. The dimension of the opening exceeds the dimension of the trancated cone on the pin. The axis of the pin is shifted with respect to the axis of the opening in the cutting plate in the direction to which the grip acts. The side of the lining is provided with a projection that interacts with answered hollow provided on the side of the holder socket. EFFECT: improved design. 2 cl, 6 dwg
