従来、シャンク端部に丈調整ねじを螺設し、かつ回転トルク受面を有するスト レートシャンク付回転工具が使用可能なワンタッチ形工具ホルダに実開平５−２ ６２１１号がある。 このものは図７〜図１３に示すようにインナスリーブ１０１又はアウタスリー ブ１０２を、ばね１０３又は１０４の力に抗して移動させ、球体１０５又は１０ ６が半径外方に逃げ得る状態とし、予めシャンク１０７端部の丈調整ねじ１０８ により丈長さを調整された回転工具の回転トルク受面１０７ａを、回り止め部材 １０９、又は１１０或いは１１１と位相を合わせて挿入して中心穴の底に当接さ せ、スリーブをばねの力で移動させると、工具ホルダ本体１１２中心穴のテーパ 溝１１２ａ又はアウタスリーブ１０２のテーパ溝１０２ａにより球体１０５又は １０６が半径方向に移動し、回転工具のシャンク部を押圧把持するもので、ワン タッチ形であるので、工具の着脱が素早く簡単に行えるばかりでなく、シャンク 軸部に螺設した丈調整ねじにより研ぎ直し直後の工具丈長さの調整が可能な回転 工具を使用すればシャンク挿入深さも一定なので、特に多軸ボール盤のように複 数本同じ工具突出長さとする必要がある用途には非常に有効で、かつ回転工具の 寿命と保守の面でも極めて経済的なものである。 Conventionally, there is a utility model 5-2 6211 as a one-touch type tool holder in which a length adjusting screw is screwed on the shank end and a rotary tool with a straight shank having a rotary torque receiving surface can be used. This one moves the inner sleeve 101 or the outer sleeve 102 against the force of the spring 103 or 104 as shown in FIGS. 7 to 13 so that the sphere 105 or 106 can escape outward in the radius. Insert the rotation torque receiving surface 107a of the rotary tool, the length of which is adjusted by the length adjusting screw 108 at the end of the shank 107, in phase with the anti-rotation member 109, 110 or 111, and contact the bottom of the center hole. When they are brought into contact with each other and the sleeve is moved by the force of the spring, the spherical body 105 or 106 is moved in the radial direction by the taper groove 112a of the center hole of the tool holder body 112 or the taper groove 102a of the outer sleeve 102 to move the shank portion of the rotary tool. It is pressed and held, and it is a one-touch type, so not only can tools be attached and removed quickly and easily, but it is also screwed onto the shank shaft. If you use a rotating tool that allows adjustment of the tool length immediately after re-sharpening with the adjusting screw, the shank insertion depth is constant, so it is especially suitable for applications where multiple tools such as multi-axis drilling machines need to have the same tool protrusion length. Is very effective and extremely economical in terms of tool life and maintenance.

従来の技術で述べた実開平５−２６２１１号のワンタッチ形工具ホルダは、回 転トルク伝達に関わる回り止め部材が螺着による固定手段で装着されているため 、しばしば使用時の切削振動等により回り止め部材の螺着力がゆるみ、回り止め 部材のずれや脱落による回転工具シャンク部への噛み込みや、回転工具の空回り が発生することがあった。このため回り止め部材を螺着後接着材で固定したり、 螺着でなく圧入により固定する等の対策が図られていたが、いずれも製作上コス ト高であったり加工精度面で問題があるばかりでなく、定期的な分解修理が困難 となり工具ホルダとしての寿命が不安定であるという問題を有していた。 本考案は従来の技術の有するこのような問題点に鑑みなされたものであり、そ の目的とするところはシャンク端部の丈調整ねじ等による丈長さを調整できるシ ャンク付回転工具も使用でき、極めて耐久性が高くかつ保守のための分解が容易 なワンタッチ形工具ホルダを提供しようとするものである。 The one-touch type tool holder of No. 5-26211 of Kaikai Hei, which has been described in the related art, is often rotated by cutting vibration during use because the detent member related to the rotation torque transmission is mounted by the fixing means by screwing. The screwing force of the stopper member was loosened, which could cause the rotation stopper member to slip or fall, resulting in the rotation tool shank being caught in the rotating tool shank or the idle rotation of the rotating tool. For this reason, measures have been taken such as fixing the anti-rotation member with an adhesive after screwing it in, or fixing it with press-fitting instead of screwing, but both have high manufacturing costs and problems in terms of processing accuracy. Not only that, but there is a problem that the tool holder has a unstable life due to the difficulty of periodic disassembly and repair. The present invention has been made in view of the above problems of the prior art, and its purpose is to use a rotary tool with a shank capable of adjusting the length by a length adjusting screw at the shank end. It is an object of the present invention to provide a one-touch type tool holder that can be manufactured, is extremely durable, and can be easily disassembled for maintenance.

以下実施例について図面にもとづき説明する。 実施例１ 本実施例はインナスリーブ方式のワンタッチ形工具ホルダで、図１，図２に示 すように工具ホルダ本体１にはインナスリーブ３を嵌装する中心穴１ａが穿設さ れており、その軸方向中程に底側が拡がるテーパ溝１ｂが削設されている。さら に工具ホルダ本体基部には加工機に取付けるねじ軸２が形成されている。このね じは加工機主軸の回転方向に対してゆるみが生じない方向に削設されたものであ る。 Embodiments will be described below with reference to the drawings. Embodiment 1 This embodiment is an inner sleeve type one-touch type tool holder. As shown in FIGS. 1 and 2, the tool holder body 1 is provided with a center hole 1a into which an inner sleeve 3 is fitted. A taper groove 1b whose bottom side expands is cut in the middle of the axial direction. Furthermore, a screw shaft 2 to be attached to the processing machine is formed on the base of the tool holder body. This screw was machined in a direction that did not cause loosening with respect to the rotation direction of the main shaft of the processing machine.
【０００８】 中心穴に嵌装されるインナスリーブ３はフランジ部を有し、インナスリーブの 胴部３ａには中心軸と直角方向に略半円状の回り止めキー４が入りインナスリー ブ３の軸方向移動時に干渉しない切欠き３ｂが削設されている。またテーパ溝１ ｂに対する胴部３ａの位置の円周３分点には内側を小径とし球体５が穴にのぞむ 貫通球座３ｃが穿設さている。この工具ホルダ本体１の中心穴１ａには挿入され たインナスリーブ３を押し出す方向に付勢する圧縮ばね６が介装されている。The inner sleeve 3 fitted in the center hole has a flange portion, and a substantially semicircular detent key 4 is inserted into the body portion 3 a of the inner sleeve in a direction perpendicular to the center axis of the inner sleeve 3. The notch 3b is cut so as not to interfere with the movement in the axial direction. Further, a penetrating ball seat 3c having a small diameter on the inside and having a spherical body 5 looking into the hole is bored at a third point of the circumference of the body portion 3a with respect to the taper groove 1b. A compression spring 6 is interposed in the center hole 1a of the tool holder body 1 to urge the inserted inner sleeve 3 in a pushing direction.
【０００９】 そして工具ホルダ本体１にはテーパ溝１ｂと切欠き３ｂに跨がり装着工具の回 転トルク受面に係合する位置で中心軸と直角方向に略半円状の回り止めキー４が 嵌装されるスリット１ｃが削設され、回り止めキー４の円弧面を覆う固定リング ７が工具ホルダ本体１外周に軸方向移動可能に嵌合されており、固定リング７は 工具ホルダ本体１の外周溝に嵌合される止め輪８により軸方向移動が規制されて いる。この固定リング７は回り止めキー４を強固に固定するものではなく不都合 な位置にずれるのを防止するためのもので、必ずしも固定リング７で回り止めキ ー４を完全に覆う必要はない。The tool holder body 1 is provided with a substantially semi-circular detent key 4 in a direction perpendicular to the central axis at a position where the tool holder body 1 straddles the taper groove 1b and the notch 3b and engages with the rotating torque receiving surface of the mounted tool. The slit 1c to be fitted is cut and a fixing ring 7 covering the arc surface of the rotation prevention key 4 is fitted to the outer periphery of the tool holder main body 1 so as to be movable in the axial direction. Axial movement is restricted by a retaining ring 8 fitted in the outer peripheral groove. This fixing ring 7 does not firmly fix the detent key 4 but prevents it from shifting to an inconvenient position, and it is not always necessary to completely cover the detent key 4 with the fixing ring 7.
【００１０】 工具ホルダに挿入する回転工具１１は図３に示すようにシャンク１２端に軸方 向と半径方向に一対のねじ穴１２ａ，１２ｂが交差して削設されており、軸方向 のねじ穴１２ａには丈調整ねじ１３が、また半径方向のねじ穴１２ｂには丈調整 ねじのゆるみ止め用固定ねじ１４が螺装されている。またシャンク１２には略半 円状の回り止めキー４の当接する回転トルク受面１２ｃが軸方向に削設されてい る。As shown in FIG. 3, the rotary tool 11 to be inserted into the tool holder has a pair of screw holes 12a and 12b formed in the end of the shank 12 so as to intersect in the axial direction and the radial direction. A length adjusting screw 13 is screwed into the hole 12a, and a locking screw 14 for locking the length adjusting screw is screwed into the radial screw hole 12b. Further, the shank 12 is provided with a rotational torque receiving surface 12c, which comes into contact with the substantially semicircular detent key 4, in the axial direction.
【００１１】 工具ホルダ本体１とインナスリーブ３を組合せるには、工具ホルダ本体１の中 心穴にばね６とインナスリーブ３を挿入後、インナスリーブ３を中心穴底側に移 動させ回転させて工具ホルダ本体１に削設されたスリット１ｃにインナスリーブ ３の球座３ｃを合わせ、スリット１ｃから球体５を球座に挿入する。３個の球体 ５を球座に入れた後、さらに回転してインナスリーブ３の切欠き３ｂを工具ホル ダ本体１のスリット１ｃに合致させ略半円状の回り止めキー４をスリット１ｃに 嵌装し、回り止めキー４の円弧面を覆うように固定リング７を工具ホルダ本体１ の外周に嵌合し、最後に固定リングの軸方向移動を防ぐ止め輪を外周溝に嵌めて 固定する。In order to combine the tool holder body 1 and the inner sleeve 3, after inserting the spring 6 and the inner sleeve 3 into the center hole of the tool holder body 1, the inner sleeve 3 is moved to the bottom side of the center hole and rotated. The ball seat 3c of the inner sleeve 3 is aligned with the slit 1c formed in the tool holder body 1, and the sphere 5 is inserted into the ball seat through the slit 1c. After putting the three spheres 5 into the ball seat, further rotate them so that the notch 3b of the inner sleeve 3 is aligned with the slit 1c of the tool holder body 1 and the semi-circular detent key 4 is fitted into the slit 1c. Then, the fixing ring 7 is fitted to the outer circumference of the tool holder body 1 so as to cover the circular arc surface of the detent key 4, and finally, a retaining ring for preventing the fixing ring from moving in the axial direction is fitted and fixed in the outer circumferential groove.
【００１２】 このように本実施例では略半円状の回り止めキー４を固定リング７で固定して おり、螺着や接着或いは圧入などによらないで、回り止め部材の振動による緩み や接着不足がなく、上述の組立工程の逆の工程で容易に分解保守できるので工具 ホルダの寿命が格段に安定向上する。このように構成された工具ホルダを加工機 の主軸にねじ軸２を螺装して固定し、予め丈調整ねじ３により丈長さを調整した 回転工具１１を、インナスリーブ３をばね６の力に抗して押し込みシャンク１２ の回転トルク受面１２ｃを略半円状の回り止めキー４の位置と一致するように位 相を合わせて挿入し、丈調整ねじ１３が中心穴１ａの底に当接するまで押し込み 、インナスリーブ３から手を放すとばね６の力でインナスリーブ３が押し出され る。As described above, in this embodiment, the substantially semicircular detent key 4 is fixed by the fixing ring 7, so that the detent member can be loosened or adhered due to the vibration of the detent member without using screwing, bonding or press fitting. Since there is no shortage and the tool holder can be easily disassembled and maintained in the reverse process of the above-mentioned assembly process, the life of the tool holder is significantly improved. The tool holder configured as described above is fixed by screwing the screw shaft 2 onto the main shaft of the processing machine, and the length of the rotary tool 11 is adjusted by the length adjusting screw 3 in advance. The push-fitting shank 12 against the rotation torque receiving surface 12c so that the rotation torque receiving surface 12c is aligned with the position of the semi-circular detent key 4, and the length adjusting screw 13 is attached to the bottom of the center hole 1a. The inner sleeve 3 is pushed out until it comes into contact, and when the hand is released from the inner sleeve 3, the inner sleeve 3 is pushed out by the force of the spring 6.
【００１３】 このときインナスリーブ３の球座３ｃに位置した球体５がテーパ溝１ｂの壁面 から受ける力により回転工具１１のシャンク１２を把持する。加工機の主軸が回 転されると回転トルクはシャンク１２の回転トルク受面１２ｃに当接したほぼ半 円状の回り止めキー４を介して確実に回転トルクが伝達され回転工具１１の切削 が可能となる。回転工具を取り外すにはインナスリーブ３をばね６の力に抗して 押し込むとテーパ溝１ｂの壁面から球体５が受ける力がなくなりシャンク把持力 が解除され取り外すことができる。At this time, the sphere 5 positioned on the ball seat 3c of the inner sleeve 3 grips the shank 12 of the rotary tool 11 by the force received from the wall surface of the taper groove 1b. When the main shaft of the processing machine is rotated, the rotational torque is reliably transmitted through the rotation lock key 4 having a substantially semicircular shape that is in contact with the rotational torque receiving surface 12c of the shank 12, and the cutting of the rotary tool 11 is prevented. It will be possible. When the inner sleeve 3 is pushed against the force of the spring 6 to remove the rotary tool, the force exerted on the spherical body 5 from the wall surface of the taper groove 1b disappears and the shank gripping force is released and the tool can be removed.
【００１４】 また本実施例は回転主軸端に雌ねじが螺設された加工機に取付ける工具ホルダ 本体基部形状であるが、図４に示すように工具ホルダ本体２１の外周円柱面２１ ａを主軸のコレットチャック等により把持し使用することも可能である。２３は インナスリーブ、２７は固定リングである。この場合、工具ホルダ本体基部のね じ軸は不要であり、工具ホルダの全長も短くなりコンパクトに構成できる。 また略半円状の回り止めキーの断面形状は回転工具のシャンク部に当接する側 が広いテーパ形や逆のテーパ形等でもよく、この場合スリットの形状はそれによ り倣った形状が好ましい。Further, in the present embodiment, the tool holder main body base shape to be attached to the processing machine in which the female thread is screwed at the end of the rotating main spindle is used. However, as shown in FIG. It is also possible to use by grasping with a collet chuck or the like. Reference numeral 23 is an inner sleeve, and 27 is a fixing ring. In this case, the screw shaft of the tool holder body base is unnecessary, and the overall length of the tool holder is shortened, so that the tool holder can be made compact. Further, the cross-sectional shape of the substantially semicircular detent key may be a taper shape in which the side contacting the shank portion of the rotary tool is wide or an inverse taper shape, and in this case, the shape of the slit is preferably a shape that follows it.
【００１５】 また略半円状とした形状も円弧の一部を弦と並行な方向に切欠いたものやそれ に類似した形状でもよく、本考案では略半円状にこれらの形状も含めている。 また本実施例では球体を３個使用したが、１個または２個として、回転工具の シャンクをインナスリーブ内周面に押し付ける形でもよい。球座を増やして球体 数を増やすことも可能である。Further, the substantially semicircular shape may be a shape in which a part of an arc is cut out in a direction parallel to the chord or a shape similar thereto. In the present invention, these shapes are also included in the substantially semicircular shape. . Further, although three spheres are used in this embodiment, the number of spheres may be one or two and the shank of the rotary tool may be pressed against the inner peripheral surface of the inner sleeve. It is also possible to increase the number of spheres and the number of spheres.
【００１６】 実施例２ 本実施例はアウタスリーブ方式のワンタッチ形工具ホルダで、図５に示すよう に工具ホルダ本体３０の外側に小径部３０ａを設け、アウタスリーブ３１を嵌装 する。工具ホルダ本体３０の小径部３０ａに中心軸と直角に削設されたスリット ３０ｂに略半円状の回り止めキー３４が嵌装されている。また工具ホルダ本体３ ０の小径部３０ａに円周上３分点に内径を小径とし球体３５を中心穴３０ｃにの ぞます貫通球座３０ｄが穿設されている。なお球座３０は球体３５を挿入した際 に小径部３０ａの外周面より球体が隠れる程度の深さである。アウタスリーブ３ １の内周面には球体３５に対する位置に工具ホルダ本体３０のねじ軸側が大径と なるテーパ溝３１ａが削設されている。Embodiment 2 This embodiment is an outer sleeve type one-touch type tool holder. As shown in FIG. 5, a small diameter portion 30a is provided outside the tool holder body 30, and an outer sleeve 31 is fitted therein. A substantially semicircular detent key 34 is fitted into a slit 30b formed in the small diameter portion 30a of the tool holder main body 30 at a right angle to the central axis. In addition, a through-ball seat 30d is formed in the small-diameter portion 30a of the tool holder main body 30 with a small inner diameter at a point 3 minutes on the circumference, with the spherical body 35 passing through the central hole 30c. The ball seat 30 has such a depth that the sphere is hidden from the outer peripheral surface of the small diameter portion 30a when the sphere 35 is inserted. A taper groove 31a having a large diameter on the screw shaft side of the tool holder body 30 is formed in a position relative to the spherical body 35 on the inner peripheral surface of the outer sleeve 31.
【００１７】 またアウタスリーブ３１の穴の回転工具挿入側には大径部３１ｂが形成されて いて工具ホルダ本体外周小径部３０ａとの間にばね３６が介装されており、小径 部３０ａの端部外周の円周溝に嵌合された止めリング３７で圧縮力が生じるよう に止められている。 この工具ホルダを組むには工具ホルダ本体の各球座３０ｄにグリスを塗り、球 体３５を挿入付着させ、また回り止めキー３４をスリットに嵌装させる。次にア ウタスリーブ３１を工具ホルダ本体３０の小径部３ａに嵌装し、ばね３６をアウ タスリーブ３１の大径部３１ｂと工具ホルダ本体外周小径部３０ａとの隙間に挿 入して止リング３７を嵌める。Further, a large diameter portion 31b is formed on the rotary tool insertion side of the hole of the outer sleeve 31, and a spring 36 is interposed between the large diameter portion 31b and the outer peripheral small diameter portion 30a of the tool holder main body, and an end of the small diameter portion 30a. A retaining ring 37 fitted in a circumferential groove on the outer periphery of the portion is secured so as to generate a compressive force. To assemble this tool holder, grease is applied to each ball seat 30d of the tool holder main body, the sphere 35 is inserted and attached, and the detent key 34 is fitted in the slit. Next, the outer sleeve 31 is fitted into the small diameter portion 3a of the tool holder main body 30, and the spring 36 is inserted into the gap between the large diameter portion 31b of the outer sleeve 31 and the tool holder main body outer peripheral small diameter portion 30a to stop the ring 37. Fit.
【００１８】 図３の回転工具１１を挿入するには、ばね３６を圧縮するようにアウタスリー ブ３１を軸方向に移動させ、回転工具１１のトルク受面１２ｃを回り止めキー３ ４に合わせてホルダ中心穴の底まで挿入し、アウタスリーブ３１を放すと、ばね ３６の圧縮力によりアウタスリーブのテーパ溝３１ａの壁面が球体３５を内方に 押しシャンク１２を把持する。回転トルクは回り止めキー３４により回転トルク 受面１２ｃを介して伝達される。To insert the rotary tool 11 of FIG. 3, the outer sleeve 31 is moved in the axial direction so as to compress the spring 36, and the torque receiving surface 12c of the rotary tool 11 is aligned with the detent key 34 to hold the holder. When it is inserted to the bottom of the center hole and the outer sleeve 31 is released, the wall surface of the taper groove 31a of the outer sleeve pushes the sphere 35 inward by the compressive force of the spring 36 and grips the shank 12. The rotation torque is transmitted by the rotation stop key 34 via the rotation torque receiving surface 12c.
【００１９】 本実施例ではアウタスリーブに削設されたテーパ溝として工具ホルダ本体３０ のねじ軸側が大径となるものを示したが、図６に示す様に、ねじ軸側が小径とな るテーパ溝３１ｃのものも可能である。 尚本実施例も加工機の主軸に取り付けるホルダ本体基部形状が実施例１と同様 にねじ軸を有するものであるが、ストレート軸など他の取り付け部形状にも通用 できるのは言うまでもない。 また回り止めキー３４の形状、球体の個数等も実施例１と同様に変更できる。In this embodiment, the taper groove formed in the outer sleeve has a large diameter on the screw shaft side of the tool holder main body 30. However, as shown in FIG. 6, a taper groove on the screw shaft side has a small diameter. A groove 31c is also possible. In this embodiment, the shape of the holder main body attached to the main shaft of the processing machine has a screw shaft as in the first embodiment, but it goes without saying that it can be applied to other shapes such as a straight shaft. Further, the shape of the detent key 34, the number of spheres, etc. can be changed as in the first embodiment.
