【０００４】[0004]
ところで、上述した従来の内周刃式正面フライスＦ0では、楔部材６を取り付 ける取付ねじ８が工具本体１の内周側から取り付けられているため、取付ねじ８ を操作する際には、凹所２へレンチ等の作業工具を挿入して狭い中で作業を行わ なければならない。従って、作業に手間がかかり、また不自然な作業姿勢を強い られるので力も入り難く、この結果、特に大径のフライスのように刃数が多い工 具の場合に、切刃チップ５の着脱作業や振れ調整作業の作業効率が著しく悪化す るという問題があった。 この考案は、このような背景の下になされたもので、特に工具本体の内周側か ら切刃チップを取り付ける場合の切刃チップの着脱作業や振れ調整作業を迅速に 行い得る転削工具を提供することを目的とする。By the way, in the above-mentioned conventional inner peripheral blade type front milling cutter F 0 , since the mounting screw 8 for mounting the wedge member 6 is mounted from the inner peripheral side of the tool body 1, when operating the mounting screw 8 It is necessary to insert a work tool such as a wrench into the recess 2 and work in a narrow space. Therefore, the work is troublesome, and it is difficult to apply force because it requires an unnatural work posture. As a result, especially in the case of a tool with a large number of blades such as a large diameter milling cutter, the work of attaching and detaching the cutting edge tip 5 is performed. There was a problem that the work efficiency of the shake adjustment work deteriorates significantly. The present invention has been made against such a background, and in particular, a cutting tool that can quickly perform attachment / detachment work of the cutting edge tip and runout adjustment work when the cutting edge tip is attached from the inner peripheral side of the tool body. The purpose is to provide.

この考案では、工具本体の軸線方向一端部に、当該工具本体の軸線方向他端側 へ陥没する凹所が形成され、この凹所の内周壁部にチップ取付溝が形成され、こ のチップ取付溝に、切刃チップが、その着座面を上記チップ取付溝の周方向に対 向する壁面の一方に当接させて挿入され、この切刃チップと上記チップ取付溝の 周方向に対向する壁面の他方との間に、楔部材が、その楔面の間隔が狭くなる側 を上記工具本体の径方向外周側へ向けて挿入され、この楔部材が上記工具本体の 雌ねじ穴にねじ込まれた取付ねじで上記工具本体の外周側へ押し込まれて上記切 刃チップが上記工具本体の周方向へ押圧されてなる転削工具において、上記取付 ねじと螺合する上記工具本体の雌ねじ穴を上記工具本体の外周表面に開口させる とともに、上記取付ねじの端部のうち、上記工具本体の外周側に向けられる端部 に、当該取付ねじを操作する作業工具と嵌合可能な嵌合部を設けることにより、 上記課題の解決を図っている。 In this invention, a recess is formed at one end of the tool body in the axial direction, the recess being recessed toward the other end of the tool body in the axial direction, and a chip mounting groove is formed in the inner peripheral wall of the recess. The cutting edge tip is inserted into the groove with its seating surface in contact with one of the wall surfaces of the tip mounting groove facing the circumferential direction, and the cutting edge tip and the wall surface of the tip mounting groove facing each other in the circumferential direction. The wedge member is inserted between the other side of the tool body and the side where the distance between the wedge surfaces becomes narrower toward the radially outer side of the tool body, and the wedge member is screwed into the female screw hole of the tool body. In a cutting tool in which the cutting edge tip is pressed to the outer peripheral side of the tool body with a screw and is pressed in the circumferential direction of the tool body, the female screw hole of the tool body that is screwed with the mounting screw is formed in the tool body. On the outer peripheral surface of the The above problem is solved by providing a fitting portion capable of fitting with a work tool for operating the mounting screw, at an end portion of the attached screw which is directed toward the outer peripheral side of the tool body. .
【０００６】 なお、ここでいう転削工具には、正面フライスの他、エンドミルや側フライス など、工具本体をその軸線回りに回転させて切削加工を行う構成のあらゆる切削 工具が含まれる。また、チップ取付溝の周方向に対向する壁面のうち、上記切刃 チップと当接する一方の壁面は、工具本体の内周壁部を削成して形成される壁面 のみならず、チップ取付溝内に挿入されたサポート部材の壁面によって構成され る場合も含まれる。In addition to the face milling cutter, the rolling tool referred to herein includes end mills, side milling cutters, and all other cutting tools configured to perform cutting by rotating the tool body around its axis. Also, of the wall surfaces facing each other in the circumferential direction of the chip mounting groove, the one wall surface that contacts the cutting edge chip is not only the wall surface formed by cutting the inner peripheral wall part of the tool body, but also the inside of the chip mounting groove.

以下、図面を参照して、本考案の一実施例を説明する。なお、上述した図４〜 図６に示す従来例と共通する構成要素には同一符号を付し、説明を省略する。 図１〜図３に示すように、本実施例の正面フライスＦ1が異なる点は、楔部材 ６を締め付ける取付ねじ２０、及びこの取付ねじ２０が装着される工具本体１の 雌ねじ穴２１の構成にある。すなわち、本実施例において、取付ねじ２０は、上 述した従来の取付ねじ８と同様に、捩れ方向を異にする順ねじ部２０ａと逆ねじ 部２０ｂとが小径のネック２０ｃを介して同軸的に連接されてなるものではある が、 当該取付ねじ２０を操作する六角レンチ（図示略）と嵌合するための六角穴（嵌 合部）２０ｄが順ねじ部２０ａの端面側に形成されている点で、従来と異なる。 なお、前記嵌合部の形状は、作業に用いられるレンチに対応する他の形状、例え ばトルクス穴であってもよい。また逆ねじ部２０ｂの端面については、六角穴２ ０ｄの有無を問わない。An embodiment of the present invention will be described below with reference to the drawings. The same components as those of the conventional example shown in FIGS. 4 to 6 are designated by the same reference numerals and the description thereof will be omitted. As shown in FIGS. 1 to 3, the point that the front milling cutter F 1 of this embodiment is different is the configuration of a mounting screw 20 for tightening the wedge member 6 and a female screw hole 21 of the tool body 1 to which the mounting screw 20 is mounted. It is in. That is, in the present embodiment, the mounting screw 20 has a forward threaded portion 20a and a reverse threaded portion 20b, which have different twisting directions, coaxial with each other via the neck 20c having a small diameter, as in the conventional mounting screw 8 described above. However, a hexagonal hole (fitting portion) 20d for fitting with a hexagonal wrench (not shown) for operating the mounting screw 20 is formed on the end face side of the forward screw portion 20a. The point is different from the conventional one. The shape of the fitting portion may be another shape corresponding to a wrench used for work, for example, a Torx hole. The end surface of the reverse threaded portion 20b may or may not have the hexagonal hole 20d.
【０００９】 また、取付ねじ２０の順ねじ部２０ａと螺合する工具本体１の雌ねじ穴２１は 、その一端がチップ取付溝４に開口せしめられる一方で、他端が工具本体１の外 周表面１ａに開口せしめられ、この他端側が開口する点でも従来のフライスＦ0 と異なっている。Further, the female screw hole 21 of the tool main body 1 that is screwed into the forward screw portion 20 a of the mounting screw 20 has one end opened to the tip mounting groove 4, while the other end is the outer peripheral surface of the tool main body 1. It is different from the conventional milling cutter F 0 in that it is opened in 1a and the other end side is opened.
【００１０】 さらに、本実施例の正面フライスＦ1では、チップ取付溝４に連接されるチッ プポケット１２と工具本体１の外周表面１ａとの間に工具本体１の略径方向に延 びる切屑排出孔２２が、各チップポケット１２に一個づつ形成されている。この 切屑排出孔２２は、チップポケット１２に排出された切屑を工具本体１の回転に 伴う遠心力によって工具本体１の外周側へ迅速に排出するためのものである。Further, in the face milling cutter F 1 of the present embodiment, chip discharge extending substantially in the radial direction of the tool body 1 between the chip pocket 12 connected to the chip mounting groove 4 and the outer peripheral surface 1 a of the tool body 1. One hole 22 is formed in each chip pocket 12. The chip discharge hole 22 is for quickly discharging the chips discharged into the chip pocket 12 to the outer peripheral side of the tool body 1 by the centrifugal force generated by the rotation of the tool body 1.
【００１１】 以上の構成からなる正面フライスＦ1においては、取付ねじ２０を、その雄ね じ部２０ａが雌ねじ穴２１を工具本体１の外周側へ向けて進む方向に回転させた 場合に、楔部材６がチップ取付溝４の奥側すなわち工具本体１の径方向外周側へ 押し込まれて切刃チップ５のすくい面５ｂが楔部材６の楔面６ａと強固に密着し 、これにより切刃チップ５が周方向へ押圧されてチップ取付溝４内に強固に保持 される。反対に、取付ねじ２０を、その雄ねじ部２０ａが雌ねじ穴２１を工具本 体１の内周側へ向けて進む方向に回転させた場合に、楔部材６がチップ取付溝４ の入口側すなわち工具本体１の径方向内周側へ後退して切刃チップ５のすくい面 ５ｂと楔部材６の楔面６ａとが離間し、これにより切刃チップ５の周方向への押 圧が解除される。In the front milling cutter F 1 having the above-described configuration, when the mounting screw 20 is rotated in the direction in which the male screw portion 20 a advances the female screw hole 21 toward the outer peripheral side of the tool body 1, The member 6 is pushed toward the inner side of the tip mounting groove 4, that is, the outer circumferential side of the tool body 1 in the radial direction, so that the rake face 5b of the cutting edge tip 5 firmly adheres to the wedge surface 6a of the wedge member 6, whereby the cutting edge tip is formed. 5 is pressed in the circumferential direction and firmly held in the chip mounting groove 4. On the contrary, when the male screw portion 20a of the mounting screw 20 is rotated in the direction in which the female screw hole 21 advances toward the inner peripheral side of the tool body 1, the wedge member 6 causes the wedge member 6 to enter the tip mounting groove 4, that is, the tool. The rake face 5b of the cutting edge tip 5 and the wedge surface 6a of the wedge member 6 are separated by retreating toward the radially inner side of the main body 1, whereby the pressing force of the cutting edge tip 5 in the circumferential direction is released. ..
【００１２】 しかして、本実施例の正面フライスＦ1では、工具本体１の雌ねじ穴２１を外 周表面１ａに開口させ、かつ取付ねじ２０の六角穴２０ｄを雌ねじ穴２１に螺合 される順ねじ部２０ａの端面に設けているから、工具本体１の雌ねじ穴２１の外 周表面１ａ側の開口端から六角レンチ等の作業工具を挿入して取付ねじ２０の六 角穴２０ｄと嵌合させることによって取付ねじ２０を操作することができる。従 って、切刃チップ５が工具本体１の凹所２内に取り付けられているにも拘らず、 楔部材６の締め付けや締め付け解除を工具本体１の外周側から行うことができ、 この結果、切刃チップ５の着脱作業や振れ調整作業を行う際の作業効率が向上す る。また、不自然な作業姿勢を強いられることがないので、作業工具に十分な力 を加えて楔部材６を強固に締め付けることができ、また、強固に締め付けられた 楔部材６を容易に取り外すことができる。Therefore, in the face milling cutter F 1 of this embodiment, the female screw hole 21 of the tool body 1 is opened on the outer peripheral surface 1 a, and the hexagonal hole 20 d of the mounting screw 20 is screwed into the female screw hole 21. Since it is provided on the end face of the screw portion 20a, a work tool such as a hexagon wrench is inserted from the opening end on the outer peripheral surface 1a side of the female screw hole 21 of the tool body 1 and fitted into the hexagon hole 20d of the mounting screw 20. This allows the mounting screw 20 to be operated. Therefore, although the cutting edge tip 5 is mounted in the recess 2 of the tool body 1, the wedge member 6 can be tightened and released from the outer peripheral side of the tool body 1. The work efficiency when attaching / detaching the cutting edge tip 5 or performing the shake adjustment work is improved. In addition, since the unnatural work posture is not forced, the wedge member 6 can be firmly tightened by applying a sufficient force to the work tool, and the firmly tightened wedge member 6 can be easily removed. You can
【００１３】 なお、本実施例では、特に取付ねじ２０を、両端に順ねじ部２０ａと逆ねじ部 ２０ｂとが設けられた構成としたが、本考案はこれに限るものではなく、例えば 一般的なボルトの頭部を楔部材６に係合させてその雄ねじ部を雌ねじ穴２１に螺 合させる等、雌ねじ穴２１へのねじ込み深さを変化させることこによって楔部材 ６を締め付けることができるものであれば、あらゆる構成のねじ部材が使用され る。また、チップ取付溝４の壁面４ａを、サポート部材１１の壁面１１ａによっ て構成しているが、サポート部材１１を省略して、チップ取付溝４のサポート受 け面２３（図１参照）自体を壁面４ａとしても良い。In the present embodiment, the mounting screw 20 has a structure in which the forward screw portion 20a and the reverse screw portion 20b are provided at both ends, but the present invention is not limited to this, and is, for example, a general screwdriver. In which the wedge member 6 can be tightened by changing the screwing depth into the female screw hole 21, for example, by engaging the head portion of the bolt with the wedge member 6 and screwing the male screw portion into the female screw hole 21. If so, screw members of all configurations are used. Further, although the wall surface 4a of the chip mounting groove 4 is configured by the wall surface 11a of the support member 11, the support member 11 is omitted and the support receiving surface 23 (see FIG. 1) of the chip mounting groove 4 itself. May be used as the wall surface 4a.
【００１４】[0014]
以上説明したように、この考案の転削工具によれば、切刃チップが工具本体の 凹所内に取り付けられる場合であっても、楔部材の締め付けや締め付けの解除を 工具本体の外周側から行うことができるので、切刃チップの着脱作業や振れ調整 作業を効率良く行うことができる。しかも、工具本体の外周側から取付ねじを操 作できるので、不自然な作業姿勢を強いられることもなく、取付ねじを操作する 作業工具に十分な力を与えて楔部材を強固に締め付けることができ、また強固に 締め付けられた楔部材を容易に取り外すことができる。 As described above, according to the rolling tool of the present invention, even when the cutting edge tip is mounted in the recess of the tool body, the wedge member is tightened or released from the outer peripheral side of the tool body. Therefore, the work of attaching and detaching the cutting edge tip and the work of adjusting the runout can be efficiently performed. Moreover, since the mounting screw can be operated from the outer peripheral side of the tool body, an unnatural work posture is not forced, and a sufficient force can be applied to the work tool operating the mounting screw to firmly tighten the wedge member. In addition, the wedge member that is firmly tightened can be easily removed.
