Title (EN) DESK-TOP CUTTING MACHINE
(FR) MACHINE DE COUPE DE BUREAU
(JA) 卓上切断機
Abstract:
(EN) Cutting performance where an attachment part of a spindle is downsized and inclined in a horizontal direction of a desk-top cutting machine is improved. A spindle 33 holding a serration 60 is formed in a cylindrical shape, and bearings 32 and 34 are arranged on an inside and an outside of the cylindrical shape, respectively, to be cantilevered with respect to a frame 15. The bearing 34 on the outside is held between the bearing 34 and an inner wall part of a cylindrical wall 16 formed at the frame 15, and the bearing 32 on the inside is fixed by a metal pin 31 press-fitted so as to extend from the frame 15 in an axial direction of the spindle 33. A fourth pulley 41 rotating the spindle 33 is arranged so that a position in the axial direction of a V-belt 42 partially overlaps with positions in the axial direction of the bearings 32 and 34.
(FR) Grâce à l'invention, les performances de coupe, lorsqu'une partie de fixation d'une broche présente une taille réduite et est inclinée dans une direction horizontale d'une machine de coupe de bureau, sont améliorées. Une broche 33 comportant une dentelure 60 est réalisée sous une forme cylindrique, et des paliers 32 et 34 sont respectivement disposés sur un intérieur et un extérieur de la forme cylindrique, de façon à se trouver en porte-à-faux par rapport à une structure 15. Le palier 34 à l'extérieur est maintenu entre le palier 34 et une partie de paroi intérieure d'une paroi cylindrique 16 formée au niveau de la structure 15, et le palier 32 sur l'intérieur est fixé par une goupille métallique 31 ajustée avec serrage de façon à s'étendre à partir de la structure 15 dans une direction axiale de la broche 33. Une quatrième poulie 41 faisant tourner la broche 33 est disposée de telle sorte qu'une position dans la direction axiale d'une courroie en V 42 chevauche partiellement des positions dans la direction axiale des paliers 32 et 34.
(JA) スピンドルの取付部を小型化して卓上切断機の左右方向に傾斜させたときの切断性能を向上させる。鋸刃60を保持するスピンドル33を円筒形に形成し、円筒形の内側と外側にそれぞれ軸受32と34を配置してフレーム15に対して片持ち支持させるようにした。外側の軸受34はフレーム15に形成された円筒壁16の内壁部分との間に保持し、内側の軸受32はフレーム15からスピンドル33の軸方向に延びるように圧入される金属製のピン31にて固定する。スピンドル33を回転させる第四プーリ41は、Vベルト42の軸方向位置が、軸受32、34の軸方向位置と部分的にオーバーラップするように配置される。
