本願発明は、ビビリ振動抑制効果が高く、しかも簡易な構造による防振工具を提供することである。   The present invention is to provide an anti-vibration tool having a high chatter vibration suppressing effect and a simple structure.

本願発明の防振工具は、工具本体内の中空部に弾性支持された錘を有する防振工具において、該防振工具の工具本体1は、切れ刃を取り付けるための先端部2、中空部3、略球状弾性体4、略円柱形状の錘5を有し、軸方向に伸びる該中空部3には該錘5が該球状弾性体4を介して弾性支持され、該錘5は質量密度14g/cm以上の金属からなることを特徴とする防振工具である。上記の構成を採用することによって、ビビリ振動抑制効果が高く、しかも簡易な構造による防振工具を提供することができる。 The anti-vibration tool of the present invention is an anti-vibration tool having a weight elastically supported by a hollow portion in a tool body. The tool body 1 of the anti-vibration tool includes a tip portion 2 and a hollow portion 3 for attaching a cutting blade. , Having a substantially spherical elastic body 4 and a substantially cylindrical weight 5, the weight 5 is elastically supported by the hollow portion 3 extending in the axial direction via the spherical elastic body 4, and the weight 5 has a mass density of 14 g. It is an anti-vibration tool characterized by comprising a metal of / cm 3 or more. By adopting the above configuration, it is possible to provide a vibration isolating tool having a high chatter vibration suppressing effect and a simple structure.

本願発明の防振工具は、球状弾性体の直径をd、錘の直径をDとしたとき、D/dは、1.2≦D/d≦1.6であることが好ましい。また球状弾性体のバネ定数調整機構を有することが好ましい。   In the vibration isolator of the present invention, D / d is preferably 1.2 ≦ D / d ≦ 1.6, where d is the diameter of the spherical elastic body and D is the diameter of the weight. It is preferable to have a spring constant adjusting mechanism for the spherical elastic body.

本願発明は、ビビリ振動抑制効果が高く、しかも簡易な構造による防振工具を提供することができた。   The present invention can provide an anti-vibration tool having a high chatter vibration suppressing effect and a simple structure.

本願発明は、球状弾性体で錘を支持し、球状弾性体自体の減衰性能を利用している。従って振動を減衰させるためのダンパー油は使用しない簡便な構造を有している。以下に本願発明の構成を説明する。
図1に示すように、工具本体1と、その先端側には正面フライス等の回転工具を取り付けるための先端部2が固定されている。工具本体1と先端部2とで構成される中空部3に略球状弾性体4を介して錘5を取り付け、慣性の大きい錘5から工具ホルダーの振動振幅に比例した反力を与えることによって動吸振器を構成し振動を減衰させる。従って、本願発明は、錘が工具本体に対して相対移動可能なダンパー機構を備えている。更に、工具本体1側の中空部の端面6、先端部2側の中空部の端面7と錘5の両端面8、9に凹部を設ける。錘5及び各々工具本体側中空部、先端部側中空部の夫々相対向する凹部端面6と8、及び凹部端面7と9の間に球状弾性体4を配置している。
本願発明の様に、錘5を球状弾性体4によって支持する方式は、錘及び中空部の工作が容易である。球状弾性体と接する工具本体と錘の端面は、錘と工具本体の軸中心が容易に一致するように、錘及び工具本体の中心部を円錐状の凹部に成形した。この円錐形状は一般に市販されている先端角90°から140°のドリルで加工する事により容易に成形でき、ダンパー油を使用しない為、高度な寸法精度を要求される加工部位が無く安価に提供する事ができる。
In the present invention, the weight is supported by the spherical elastic body, and the damping performance of the spherical elastic body itself is used. Therefore, the damper oil for damping the vibration has a simple structure that does not use it. The configuration of the present invention will be described below.
As shown in FIG. 1, a tool body 1 and a tip 2 for attaching a rotary tool such as a face mill are fixed to the tip of the tool body 1. A weight 5 is attached to a hollow portion 3 composed of a tool body 1 and a tip portion 2 via a substantially spherical elastic body 4, and is moved by applying a reaction force proportional to the vibration amplitude of the tool holder from the weight 5 having a large inertia. A vibration absorber is constructed to attenuate the vibration. Therefore, the present invention includes a damper mechanism in which the weight can move relative to the tool body. Further, a hollow portion is provided on the end surface 6 of the hollow portion on the tool body 1 side, the end surface 7 of the hollow portion on the tip portion 2 side, and both end surfaces 8 and 9 of the weight 5. The spherical elastic body 4 is disposed between the weight 5 and the recess end surfaces 6 and 8 and the recess end surfaces 7 and 9 that face the tool body side hollow portion and the tip end side hollow portion, respectively.
As in the present invention, the method of supporting the weight 5 by the spherical elastic body 4 is easy to work on the weight and the hollow portion. The center part of the weight and the tool body was formed into a conical recess so that the end surface of the tool body and the weight contacting the spherical elastic body could easily coincide with the axial center of the weight and the tool body. This conical shape can be easily formed by machining with a commercially available drill with a tip angle of 90 ° to 140 °, and since no damper oil is used, there is no machining part that requires high dimensional accuracy, and it is provided at low cost. I can do it.

本願発明の錘5の質量密度を14g/cm以上の金属に規定する。質量密度を14g/cm以上とする理由は、14g/cm未満の金属では所定の防振効果を得ることができないからである。その他の理由としては、14g/cm未満の金属を用いた場合、防振効果を得るために必要な重量を確保しようとすると、略円柱形状をした錘の全長が長くなってしまう。これに伴って中空部長さも長くなることから、工具本体の剛性が低下する不都合を回避するためである。例えばこれを満足する金属は、質量密度14.9g/cmの超硬合金等が挙げられる。より好ましくは質量密度18g/cmの金属を使用することである。この場合は例えば、タングステン系合金(ヘビーメタル)などが挙げられ、好ましい選択である。
本願発明で用いる球状弾性体4は、例えばJIS K6301規定のスプリング式A型JIS硬度計によるゴム硬度Hs30〜50の耐熱性及び耐摩耗性に優れるフッ素系ゴム又はウレタンゴムを使用することが望ましい。この理由は、比較的重量のある錘5を弾性支持するのに好適な剛性と、防振効果を得るために必要な弾性を有しているからである。また、球状弾性体4と工具本体とが接触する端面6、この他の端面7、8、9の表面状態は、滑らかな面とすることが好ましい。球状弾性体及び夫々の端面は潤滑性を有する表面状態とすることがより好ましい。
The mass density of the weight 5 of the present invention is defined as 14 g / cm 3 or more of metal. The reason why the mass density is 14 g / cm 3 or more is that a predetermined vibration isolating effect cannot be obtained with a metal of less than 14 g / cm 3 . As another reason, when a metal of less than 14 g / cm 3 is used, if an attempt is made to secure a weight necessary for obtaining a vibration isolation effect, the overall length of the substantially columnar weight is increased. This is in order to avoid the disadvantage that the rigidity of the tool main body is lowered because the length of the hollow portion is increased accordingly. For example, a metal satisfying this includes a cemented carbide having a mass density of 14.9 g / cm 3 . More preferably, a metal having a mass density of 18 g / cm 3 is used. In this case, for example, a tungsten-based alloy (heavy metal) can be used, which is a preferable choice.
As the spherical elastic body 4 used in the present invention, it is desirable to use, for example, fluorine-based rubber or urethane rubber excellent in heat resistance and wear resistance of rubber hardness Hs30 to 50 by a spring type A-type JIS hardness meter defined in JIS K6301. This is because it has rigidity suitable for elastically supporting the relatively heavy weight 5 and elasticity necessary for obtaining a vibration isolation effect. Moreover, it is preferable that the surface state of the end surface 6 where the spherical elastic body 4 and the tool body are in contact with each other, and the other end surfaces 7, 8, 9 are smooth surfaces. It is more preferable that the spherical elastic body and each end face have a surface state having lubricity.

球状弾性体の直径をd、錘の直径をDとしたとき、D/dは、1.2≦D/d≦1.6とすることによって、より優れた防振効果を得ることができ、好ましい。D/d値が1.2未満の場合、錘の凹部両端面8、9の容積が大きくなることから錘の体積が減少して、有効な防振効果を得ることができない。また、球状弾性体を組み合わせた全長が必要以上に長くなり中空部の長さも増大して工具本体の剛性が低下する不都合がある。D/d値が1.6を超えて大きい場合は、球状弾性体による錘の安定した弾性支持が困難となり十分な防振効果が得られない。これは、錘支持に必要な球状弾性体の剛性が不足するためである。また錘の振動変位が大きくなって、対向する凹部面による支持部から脱落する恐れがある。更に、錘の振動変位が大きくなると、錘が中空部の内壁と接触する恐れがある。ここで、錘が中空部の内壁と接触するのを回避するために、径方向に適切な間隙を設けることが必要である。例えば、中空部の内径をGとしたとき、(G−D)/2の値は、1.5から2.5mmの範囲とすることが好ましい。更に、間隙部に適切な潤滑材を用いることによって、錘と球状弾性体との接触抵抗が低減され好ましい。   When the diameter of the spherical elastic body is d and the diameter of the weight is D, D / d is 1.2 ≦ D / d ≦ 1.6. preferable. When the D / d value is less than 1.2, since the volume of the concave end faces 8 and 9 of the weight increases, the volume of the weight decreases and an effective anti-vibration effect cannot be obtained. Further, there is a disadvantage that the total length of the combination of the spherical elastic bodies becomes longer than necessary, the length of the hollow portion is increased, and the rigidity of the tool body is lowered. When the D / d value is larger than 1.6, it is difficult to stably support the weight with the spherical elastic body, and a sufficient vibration-proofing effect cannot be obtained. This is because the rigidity of the spherical elastic body necessary for supporting the weight is insufficient. Further, the vibration displacement of the weight increases, and there is a possibility that the weight will fall off from the support portion by the opposing concave surface. Further, when the vibration displacement of the weight increases, the weight may come into contact with the inner wall of the hollow portion. Here, in order to prevent the weight from coming into contact with the inner wall of the hollow portion, it is necessary to provide an appropriate gap in the radial direction. For example, when the inner diameter of the hollow portion is G, the value of (GD) / 2 is preferably in the range of 1.5 to 2.5 mm. Furthermore, it is preferable to use an appropriate lubricant for the gap portion because the contact resistance between the weight and the spherical elastic body is reduced.

図2に本願発明による別の実施形態の防振工具断面図を示す。工具本体1の先端側には先端部2が固定されている。この先端部2は軸方向の中心部に貫通ネジ穴を有し、ここを通るネジ部材10の1端面は凹部形状をなし球状弾性体の支持部として機能している。このネジ部材10は、軸方向に移動することが可能であるため、球状弾性体のバネ定数の調整機構として作用することから、防振効果を調整することが可能である。
ここで、弾性支持部の構造について述べる。工具本体側の端面6及びネジ部材10の端面11の凹部形状深さは、軸方向における錘5と工具本体1との間隙及び錘5と先端部2との間隙が1.5から3mmになるように設定することが好ましい。例えば凹部形状の深さは、d値の0.2から0.3倍とすることが好ましい。一方、本願発明を組立の容易さと球状弾性体を安定して支持させる事を目的として、錘の両端面8、9の凹部形状の深さは、d値の0.5から0.6倍とすることが好ましい。
本願発明における別の実施形態の1例を図3に示す。シャンク部材12にねじ込んで使用される切れ刃部13の後端面側に中空部を設け、前記の実施形態と同様に球状弾性体4と錘5を中空部3に挿入し、ねじ部材10を用いて球状弾性体4のバネ定数を調整可能に錘5を支持する形態である。
FIG. 2 shows a cross-sectional view of an anti-vibration tool according to another embodiment of the present invention. A tip 2 is fixed to the tip of the tool body 1. The tip portion 2 has a through screw hole at the center in the axial direction, and one end surface of the screw member 10 passing therethrough has a concave shape and functions as a support portion for the spherical elastic body. Since the screw member 10 can move in the axial direction, the screw member 10 acts as a mechanism for adjusting the spring constant of the spherical elastic body, so that the vibration isolation effect can be adjusted.
Here, the structure of the elastic support portion will be described. The recess shape depth of the end surface 6 on the tool body side and the end surface 11 of the screw member 10 is such that the gap between the weight 5 and the tool body 1 in the axial direction and the gap between the weight 5 and the tip 2 is 1.5 to 3 mm. It is preferable to set so. For example, the depth of the concave shape is preferably 0.2 to 0.3 times the d value. On the other hand, for the purpose of assembling the present invention and supporting the spherical elastic body stably, the depth of the concave shape of both end faces 8, 9 of the weight is 0.5 to 0.6 times the d value. It is preferable to do.
An example of another embodiment of the present invention is shown in FIG. A hollow portion is provided on the rear end face side of the cutting edge portion 13 used by being screwed into the shank member 12, and the spherical elastic body 4 and the weight 5 are inserted into the hollow portion 3 in the same manner as in the above embodiment, and the screw member 10 is used. Thus, the weight 5 is supported so that the spring constant of the spherical elastic body 4 can be adjusted.

本願発明の工具を作成し、防振効果を確認した。工具寸法である先端工具径:φ50mm、工具長さ:400mm、中空部長さ:130mm、中空部直径G:39mm、中空部先端位置:工具先端から60mm、錘長さ:115mm、錘直径D:36mm、錘材質:質量密度18g/cmの金属材、球状弾性体直径d:25.4mm、球状弾性体材質:ゴム硬度50Hsのフッ素系ゴム、を用いて本発明例1を作製した。優れた防振効果を得るために、上記の数値は、錘寸法については減衰を考慮した1自由度振動系の運動方程式等から算出し、同様に中空部寸法及び球状弾性体寸法を決定した。本発明例2から5は、D/d値を変化させた。本発明例6から9及び比較例6、7は、錘材質の質量密度を変化させた。錘の質量密度は、複数の質量密度の異なる金属を組み合わせた錘を作成することによって調整した。従来例12は防振機構無しのものを使用した。
まず、防振効果を確認するために、工具の周波数応答を測定し振動減衰性能を比較した。図4に本発明例1と従来例12の周波数応答を示す。図4より、縦軸の振幅値を比較すると、本発明例1の振幅のピーク値N、従来例12のピーク値Mとしたとき、N/Mは26%であった。振幅のピーク値の比であるN/M値が45%以下に低減することで防振効果に有効であると判断した。従って、本発明例1は大幅な振動減衰性能を示したといえる。
The tool of the invention of the present application was created and the anti-vibration effect was confirmed. Tool size: tool diameter: 50 mm, tool length: 400 mm, hollow part length: 130 mm, hollow part diameter G: 39 mm, hollow part tip position: 60 mm from the tool tip, weight length: 115 mm, weight diameter D: 36 mm Example 1 of the present invention was prepared using a weight material: a metal material having a mass density of 18 g / cm 3 , a spherical elastic body diameter d: 25.4 mm, and a spherical elastic body material: a fluorine-based rubber having a rubber hardness of 50 Hs. In order to obtain an excellent anti-vibration effect, the above numerical values were calculated from the equation of motion of a one-degree-of-freedom vibration system in consideration of damping for the weight dimensions, and similarly the hollow part dimensions and spherical elastic body dimensions were determined. In Invention Examples 2 to 5, the D / d value was changed. In Invention Examples 6 to 9 and Comparative Examples 6 and 7, the mass density of the weight material was changed. The mass density of the weight was adjusted by creating a weight combining a plurality of metals having different mass densities. The conventional example 12 used the thing without an anti-vibration mechanism.
First, in order to confirm the anti-vibration effect, the frequency response of the tool was measured and the vibration damping performance was compared. FIG. 4 shows the frequency response of Example 1 of the present invention and Conventional Example 12. From the comparison of the amplitude values on the vertical axis shown in FIG. 4, the N / M was 26% when the peak value N of the amplitude of Example 1 of the present invention and the peak value M of Conventional Example 12 were used. The N / M value, which is the ratio of the peak amplitude values, was reduced to 45% or less, and it was determined that the vibration-proofing effect was effective. Therefore, it can be said that Example 1 of the present invention showed significant vibration damping performance.

表1の結果より、本発明例1から6は、従来例12よりも2倍以上の軸方向切り込み量が得られた。本発明例1は、本願発明のベストモードを示す。評価結果は、最も優れていた。本発明例2、3、6から9は、本願発明が規定しているD/d値が1.2≦D/d≦1.6を満たしている例を示す。評価の結果、従来例12の略1.5倍以上の軸方向切り込み量であった。一方、本発明例4、5は、D/d値が2、1.1の場合を示すが、本発明例2、3と比較して劣る結果となった。D/d値が2の場合は、球状弾性体による錘の安定した弾性支持が困難となり十分な防振効果が得られなかった。D/d値が1.1の場合、錘の凹部両端面の容積が大きくなることから錘の体積が減少して、有効な防振効果を得ることができなかったためである。本発明例6から9はD/d値を一定として、錘の質量密度を変化させた場合を示す。錘の質量密度を14g/cm以上とすることによって、有効な防振効果を得ることができた。比較例10、11は本願発明が規定している錘の質量密度の範囲外であった。評価の結果、比較例10は従来例12と同等であったが、比較例12は従来例12よりも劣る結果となった。これは錘の質量密度が小さいため所定の防振効果を得るための重量を確保する事が出来なかったためである。 From the results shown in Table 1, Examples 1 to 6 of the present invention obtained an axial depth of cut more than twice that of Conventional Example 12. Invention Example 1 shows the best mode of the present invention. The evaluation result was the most excellent. Invention Examples 2, 3, 6 to 9 show examples in which the D / d value defined by the present invention satisfies 1.2 ≦ D / d ≦ 1.6. As a result of the evaluation, the axial cut amount was approximately 1.5 times or more that of Conventional Example 12. On the other hand, Examples 4 and 5 of the present invention show cases where the D / d values are 2 and 1.1, but the results are inferior to those of Examples 2 and 3 of the present invention. When the D / d value is 2, stable elastic support of the weight by the spherical elastic body becomes difficult, and a sufficient vibration-proofing effect cannot be obtained. This is because when the D / d value is 1.1, the volume of the both end surfaces of the concave portion of the weight increases, so the volume of the weight decreases, and an effective anti-vibration effect cannot be obtained. Invention Examples 6 to 9 show cases where the mass density of the weight is changed while the D / d value is constant. By setting the mass density of the weight to 14 g / cm 3 or more, an effective vibration isolation effect could be obtained. Comparative Examples 10 and 11 were outside the mass density range defined by the present invention. As a result of the evaluation, Comparative Example 10 was equivalent to Conventional Example 12, but Comparative Example 12 was inferior to Conventional Example 12. This is because the weight for obtaining a predetermined vibration isolating effect could not be secured because the mass density of the weight was small.
