本考案は、インターナルクランクシャフトミラー等に用
いる内刃工具を保持する回転工具ドラムの改良に関する
ものである。[Detailed Description of the Invention] The present invention relates to an improvement of a rotary tool drum that holds an inner cutter tool used for an internal crankshaft mirror or the like.
インターナルクランクシャフトミラーは第1図に示すよ
うになっていて、ベッド1に対向方向に摺動するように
設けた工具ガイド本体2,2の中央部に上下動するよう
にした工具支持体3があり、これに内部がテーパ状の中
空になった回転工具ドラム4が回転自在に支持されてい
る。The internal crankshaft mirror is designed as shown in FIG. 1, and has a tool support 3 which is movable up and down in the center of tool guide bodies 2, 2 which are provided to slide in opposite directions on the bed 1. A rotary tool drum 4 having a tapered hollow interior is rotatably supported therein.
そしてこの回転工具ドラム4がギヤトレン5にて回転さ

固着した内刃工具6にてチャック7.8に保持されたク
ランクシャフト(図示せず)のジャーナル部を旋削する
ようになっている。When the rotary tool drum 4 is rotated by the gear train 5, a crankshaft (not shown) is held by the chuck 7.8 by the inner cutting tool 6 fixed to the inner surface of the small diameter side of the rotary tool drum 4. The journal part of the machine is turned.

示のように比較的薄いドラム状になっているため、旋削
時の発熱した切粉が接触するとその熱影響を受けてし1
い、回転工具ドラム4は発熱により変形が生じ、これが
内刃工具6に影響して加工精度が低下するという問題が
あった。However, the part of the rotary tool drum 4 attached to the internal crankshaft mirror that is supported by the bearing 9 has a relatively thin drum shape as shown in the figure, so if it comes into contact with the chips generated during turning, it will be damaged. Under the influence of heat 1
However, there was a problem in that the rotary tool drum 4 was deformed due to heat generation, and this affected the inner cutter tool 6, resulting in a decrease in machining accuracy.
本考案は上記のことにかんがみなされたもので、切粉に
よる熱影響を少なくして発熱による加工精度の低下を防
止できるようにした回転工具ドラムを提供しようとする
ものである。The present invention has been made in consideration of the above-mentioned problems, and aims to provide a rotary tool drum that can reduce the thermal influence of chips and prevent deterioration of machining accuracy due to heat generation.
以下その構成を第2図に示した実施例に基づいて説明す
る。The configuration will be explained below based on the embodiment shown in FIG.
な卦第2図に釦いて、第1図と同一符号で示す部材は同
一部材であることを示す。In Figure 2, members designated by the same reference numerals as those in Figure 1 indicate the same members.
回転工具ドラム4の内壁4aに、この内壁4aとの間に
内壁4aに沿う略平行の隙間10をあけてテーパ状の薄
い鉄板等からなる筒部材11を嵌合同着する。A cylindrical member 11 made of a tapered thin iron plate or the like is fitted onto the inner wall 4a of the rotary tool drum 4 with a gap 10 substantially parallel to the inner wall 4a formed therebetween.
筒部材6には複数個の通気用の孔12をあけて釦く。A plurality of ventilation holes 12 are made in the cylindrical member 6 and the button is pressed.
しかして加工時に発生する切粉は回転工具ドラム4の内
周部に飛散してから外方へ除去される。Chips generated during machining are scattered around the inner circumference of the rotary tool drum 4 and then removed outward.
このとき発熱した切粉は回転工具ドラム4の内周部に飛
散してもその内壁4aには隙間10をあけて筒部材11
が嵌合固着しであるので、この筒部材11が切粉によっ
て加熱されても隙間10内の空気が断熱作用をなしてそ
の熱は回転工具ドラム4にGま伝わらない。Even if the chips generated at this time are scattered on the inner circumference of the rotary tool drum 4, a gap 10 is left in the inner wall 4a of the cylindrical member 11.
Since the cylindrical member 11 is fitted and fixed, even if the cylindrical member 11 is heated by chips, the air within the gap 10 acts as a heat insulator and the heat is not transmitted to the rotary tool drum 4.
捷た筒部材11がテーパ状になっていることにより、回
転工具ドラム4が回転することにより、隙間10内の空
気に円心力が作用して隙間10内の空気は大径端から流
出し、従って隙間10内に筒部材11の小径側から大径
側に向かう空気流が生じ、隙間10内の空気の温度上昇
が防止される。Since the cut cylindrical member 11 has a tapered shape, when the rotary tool drum 4 rotates, a circular force acts on the air in the gap 10, and the air in the gap 10 flows out from the large diameter end. Therefore, an air flow from the small diameter side to the large diameter side of the cylindrical member 11 is generated within the gap 10, and the temperature of the air within the gap 10 is prevented from rising.
捷た筒部材11の熱はこれに設けた複数個の通気用の孔
12からも発散される。The heat of the shredded cylindrical member 11 is also radiated through a plurality of ventilation holes 12 provided therein.
本考案に係る回転工具ドラムは、上記詳述したようにな

内壁4aに沿う略平行の隙間10をあけてテーパ状の筒
部材11を嵌合固着したから、切粉による熱影響が少な
くなり、発熱による加工精度の低下を防止することがで
きる。The rotary tool drum according to the present invention is as described in detail above, and is a rotary tool drum having a tapered hollow interior and an inner cutter tool 6 fixed to the inner surface on the small diameter side. Since the tapered cylindrical member 11 is fitted and fixed to the inner wall 4a with a gap 10 that is substantially parallel to the inner wall 4a, the thermal influence of chips is reduced, and the machining accuracy due to heat generation is reduced. The decline can be prevented.
そしてさらに本考案によれば下記のような本願の考案特
有の効果を奏することができる。Further, according to the present invention, the following effects unique to the present invention can be achieved.
すなわち、(1)回転工具ドラム4の内側に隙間10を
設けたことにより、この隙間10内の空気層にて断熱効
果を得ることができ、特別な断熱材を必要とすることが
なく、安価な装置にて所定の効果を得ることができる。That is, (1) by providing the gap 10 inside the rotary tool drum 4, the air layer within this gap 10 can provide a heat insulating effect, eliminating the need for a special heat insulating material and making it inexpensive. Predetermined effects can be obtained with a suitable device.
(2)筒部材11がテーパ状になっていることにより、
回転工具ドラム4の回転に従って隙間10内にその小径
側から大径側に向かう空気流が生じ、この空気流による
冷却効果を得ることができる。(2) Since the cylindrical member 11 is tapered,
As the rotary tool drum 4 rotates, an airflow is generated within the gap 10 from the small diameter side to the large diameter side, and a cooling effect can be obtained by this airflow.
