【考案の詳細な説明】
この考案は長尺材に対する切削加工に当り被削材に生ず
る振動を防止せんことを目的とした長尺材の振動防止装
置に関するものである。[Detailed Description of the Invention] This invention relates to a vibration prevention device for a long material whose purpose is to prevent vibrations generated in a workpiece during cutting of a long material.
旋盤による金属加工では被削物の直径に比して長さが長
くなればなるほど切削中の被削材に一定の振動が発生し
易くなり、俗に所謂１ビビリヨが起る。In metal processing using a lathe, the longer the length of the workpiece compared to its diameter, the more likely a certain vibration will occur in the workpiece being cut, commonly known as vibration.
この１ビビリヨは完成品の寸法や面粗度に大きく影響す
るので、これをいかに防ぐかが加工上の問題点ともなる
ものであり、本案は加工用刃物と被削材を表面から加圧
する２個のローラーとで、被削物を押えて撓みを防ぎ且
つ振動を吸収することによって安定した条件下での精確
なる切削加工を得しめんとしたものである。This 1-chattering greatly affects the dimensions and surface roughness of the finished product, so how to prevent it is a problem in processing.This proposal involves applying pressure to the machining cutter and workpiece from the surface. It is intended to achieve precise cutting under stable conditions by holding down the workpiece to prevent deflection and absorbing vibrations.
次に本案実施例を図面について説明する。Next, an embodiment of the present invention will be explained with reference to the drawings.
１は直径に比べて長さの長い黒皮丸棒（被削材）で旋盤
加工すべく一端部をチャック２に挟着され他端はテール
ストック３にて押込されている。1 is a black leather round bar (work material) that is longer in length than its diameter, and one end is clamped in a chuck 2 for lathe processing, and the other end is pushed in with a tail stock 3.
４は刃物台、５はバイトである。６は被削材１に対し刃
物台４め反対側に設けたバイト５の刃先接近位置に配し
たローラーブラケットで、被削材１の上面部に上下調整
可能ならしめた下圧ローラー７と当該材の側面部に対接
すべき側圧ローラー８とが軸装されている。4 is a tool rest, and 5 is a cutting tool. Reference numeral 6 denotes a roller bracket arranged at a position close to the cutting edge of the cutting tool 5 installed on the opposite side of the tool rest 4 with respect to the workpiece 1, and a lower pressure roller 7 which is vertically adjustable on the upper surface of the workpiece 1 and the corresponding roller bracket. A side pressure roller 8 to be in contact with the side surface of the material is mounted on a shaft.
この２個のローラー７．８は架軸９の軸受１０とローラ
一本体１１との間に硬質ゴム１２が介装されている。In these two rollers 7.8, hard rubber 12 is interposed between the bearing 10 of the rack shaft 9 and the roller main body 11.
１３はローラーの外側蓋板である。上記のローラーブラ

進退自在とされる。13 is an outer cover plate of the roller. The above-mentioned roller bracket 6 is fixed to a sliding shaft 15 fitted in a support body 14 that can move forward and backward in the longitudinal direction of the workpiece 1 together with the tool rest 4, and the shaft end is fixed to the support body 14. It is connected to the piston rod 16' of the cylinder 16 so that it can move forward and backward in a direction perpendicular to the cutting material.

動を規制するとともに被削材黒皮の凹凸をやわらげショ
ックを吸収することによって１ビビリヨ防止ができる。In this case, in the above configuration, the cutting material 1 is a round bar with the longest length compared to the diameter, so when it is rotated, it is expected that one chatter will naturally occur, but the cutting material 1 is a round bar with the longest length compared to the diameter. At the position immediately before the cutting, the lower pressure roller 7 and the side pressure roller 8 press the material from the upper surface and the surface facing the cutting tool, and each roller 7.8 has a hard rubber 12 inside the lower layer of the roller main body 11. Therefore, it is possible to prevent vibration by regulating the vibration of the cutting material, softening the unevenness of the black skin of the cutting material, and absorbing the shock.
而して切削材の径の変化に対処するためには下圧ローラ
ー７が上下に調整可能であり、側圧ローラー８はシリン
ダ１６によって側面からの加圧調整が為されるものであ
る。In order to cope with changes in the diameter of the cutting material, the lower pressure roller 7 can be adjusted up and down, and the side pressure roller 8 is adjusted to be pressurized from the side by a cylinder 16.
本案は上記の如（バイトの加工位置に接近して被削材に
対する刃先加圧に抗して２個のローラーが上面及び側面

ョ現象を懸念することなしに作業し得られるなど実用的
価値は多大とされる。This idea is as described above (approximately the machining position of the cutting tool, and the two rollers resist the pressure of the cutting edge against the workpiece and press the long workpiece from the top and side to prevent it from bending, and the rollers are made of hard rubber. Since the inner layer absorbs vibrations, rigid materials can be machined under extremely stable conditions and precisely cut and changed, and work can be performed without worrying about the vibration phenomenon, which is said to have great practical value.
