Abstract:
A cutter device for a planing machine, comprising:a cylindrical cutter seat having opposite end faces and a cylindrical surface between said end faces, each of said end faces having a coupling shaft that extends co-axially therefrom, said cylindrical surface being formed with an axially extending cutter receiving groove that extends from one of said end faces through the other one of said end faces, said cutter receiving groove being defined by a blade supporting wall, a fastener bearing wall opposite to said blade supporting wall, and a groove bottom interconnecting said blade supporting wall and said fastener bearing wall;a pair of positioning members, each of which is sleeved on a respective one of said coupling shafts of said cutter seat, and each of which has a large-diameter ring portion and a small-diameter ring portion that extends co-axially from one side of said large-diameter ring portion toward a respective one of said end faces of said cutter seat;an elongate cutting blade disposed in said cutter receiving groove, and having a wall bearing side that leans on said blade supporting wall, a force bearing side opposite to said wall bearing side, a longitudinal base edge, and a longitudinal blade edge that is opposite to said base edge and that projects relative to said cylindrical surface of said cutter seat, said cutting blade further having opposite lateral end portions, each of which projects relative to a respective one of said end faces of said cutter seat and abuts against said large-diameter ring portion of a respective one of said positioning members, said base edge being supported on said small-diameter ring portions of said positioning members at said lateral end portions of said cutting blade;an elongate press member disposed in said cutter receiving groove adjacent to said force bearing side of said cutting blade; andreleasable tightening means for forcing said press member away from said fastener bearing wall to enable said press member to press tightly said cutting blade against said base supporting wall.
