ASSEMBLED MILLING CUTTER FOR WOOD WORKING Russian patent published in 1997 - IPC

FIELD: wood-working industry, in particular, rotary cutting tool in wood-working machines. SUBSTANCE: milling cutter has body with cutter slots. Installed in slots are cutters and clamping wedges, device for fastening the wedges which includes eccentric clamp in form of eccentric shaft installed with its ends in walls of body provided with retainer in form of spring-loaded shaft with socket for wrench and splined joint, one part of which contacts body. This makes it possible to fix the eccentric shaft in operating position to prevent noncontrolled turning of the latter in tool operation. Splines are inclined to the side opposite to tool rotation to provide for torque and to make for reduction of wear of joint. Region of contact of eccentric shaft with clamping wedge over its entire width precludes possibility of nonuniform attachment resulting in cutter loosening. This results, in reduction of time for attachment of cutters, higher reliability of their fastening and convenience in installation. EFFECT: higher efficiency. 3 cl, 3 dwg
