BLADE HOLDER OF WOOD WORKING MACHINE AND METHOD FOR POSITIONING BLADE IN BLADE HOLDER OF WOOD WORKING MACHINE

摘要

PURPOSE: To easily stop a plurality of positioning members by a method wherein a blade holder comprises a blade holding surface disposed along the longitudinal direction of a blade mouthpiece and a plurality of positioning members fixed in the longitudinal direction of the blade mouthpiece and each provided with a flat reference surface coming into close contact with a carrying surface of the blade mouthpiece. ;CONSTITUTION: A bolt is fastened, and a nut is moved along a screw part to be pressed against a step part, whereby a plate 20 serving as a positioning member of a blade holder 11 is fixed to a carrying surface 22 of a blade mouthpiece 15. The blade holder 11 is placed on a placing mount 37 with the blade mouthpiece 15 showing down so that two adjacent side faces 60A, 60B are in close contact with a holding surface 43A of a holding arm 43. Then, a blade holding surface 21 is set approximately horizontally. A blade 23 and a back plate 24 are integrally moved along the blade holding surface 21 toward a reference surface 20A in a horizontal direction. A blade tip 25 abuts against the reference surface 20A at two points and comes to a stop. In this manner, the blade 23 can be positioned in the width direction thereof by disposing the blade tip 25 to be flush with the carrying surface 22.;COPYRIGHT: (C)1995,JPO
