Description

【発明の名称】かんな盤 [Name of invention] Planer

【０００８】
【課題を解決するための手段】
上記目的は、かんな胴の軸方向に形成した複数個の刃物収納溝と、該刃物収納溝内に収納される裏刃と、遠心固定板と、該遠心固定板を外周方向に付勢するバネとを有し、前記裏刃を介して前記遠心固定板の遠心力で刃物を圧接して固定する構造であって、前記刃物収納溝は、第１側面と、前記第１側面に対向しかんな胴の外周面の開口部に向かうにつれて狭くなる方向に傾けた第２側面と、裏刃の底面と当接する基準面とを持ち、前記遠心固定板は、前記刃物収納溝の前記開口部に向かうにつれて相互間隔が小さくなる一対の対向斜面で、前記第２側面に当接する一方の斜面と、前記裏刃に当接するもう一方の斜面とを持ち、前記裏刃は、前記遠心固定板に当接する面と、前記刃物に係合する係合部と、前記刃物収納溝の前記第１側面に当接する面と、前記刃物収納溝の前記基準面と当接する底面とを持つ構成をしたかんな盤において、前記裏刃に前記基準面に当接可能な調整ねじを螺設することにより達成される。[0008]
[Means for solving the problem]
The object of the present invention is to provide a structure having a plurality of blade storage grooves formed in the axial direction of a plane body, back blades stored in the blade storage grooves, a centrifugal fixing plate, and a spring for biasing the centrifugal fixing plate in the outer peripheral direction, in which the blades are pressed and fixed by the centrifugal force of the centrifugal fixing plate via the back blades, and the blade storage grooves have a first side surface, a second side surface facing the first side surface and inclined in a direction narrowing toward the opening on the outer peripheral surface of the plane body, and a reference surface that abuts against the bottom surface of the back blade, and the centrifugal fixing plate is This is achieved by threading an adjustment screw into the back blade that can abut against the reference surface in a planing machine having a pair of opposing inclined surfaces whose distance from each other decreases toward the opening of the tool storage groove, one inclined surface abutting against the second side surface and the other inclined surface abutting against the back blade, and the back blade having a surface abutting against the centrifugal fixed plate, an engaging portion that engages with the blade, a surface abutting against the first side surface of the tool storage groove, and a bottom surface abutting against the reference surface of the tool storage groove.

Claims
