図１の切削工具１は、先端に切刃３を具備する工具本体２と、工具本体２の取り付け位置を決めるための位置決め部材４と、位置決め部材４を工具本体２に装着する複数本（図１では２本）のネジ５と、から構成されており、図１（ｂ）によれば、工具本体２はその先端に切刃３を有するスローアウェイチップ６がネジ５’によって取り付けられている。   The cutting tool 1 in FIG. 1 includes a tool body 2 having a cutting edge 3 at the tip, a positioning member 4 for determining the mounting position of the tool body 2, and a plurality of tools for mounting the positioning member 4 on the tool body 2 (see FIG. 1). 1 is composed of two screws 5, and according to FIG. 1 (b), the tool body 2 has a throw-away tip 6 having a cutting edge 3 attached to the tip thereof by a screw 5 ′. .

また、図１（ａ）に示すように、各切削工具１の位置決め部材４の後端部をそれぞれ刃物台９に当接させることによって、複数の切削工具１の各々の切刃３が所定の長さだけ突出して同じ高さに揃った位置で刃物台９に取り付けられている。そして、各切削工具１はプログラム制御によって順次使用される。   Moreover, as shown to Fig.1 (a), by making the rear-end part of the positioning member 4 of each cutting tool 1 contact each tool post 9, each cutting blade 3 of the some cutting tool 1 is predetermined | prescribed. It is attached to the tool post 9 at a position that protrudes the length and is aligned at the same height. Each cutting tool 1 is sequentially used under program control.

ここで、位置決め部材４は主面が矩形の板状であり、かつ複数個のネジ穴７が矩形の回転中心Ｏに対して非対照の位置に設けられており、複数個のネジ穴７のうちの２個以上のネジ穴７にて工具本体２にネジ止めしている。
Here, the positioning member 4 is a plate having a rectangular main surface, and a plurality of screw holes 7 are provided at positions that are not contrasted with respect to the rectangular rotation center O. The tool body 2 is screwed with two or more screw holes 7.

切削工具１の刃物台９からの突き出し長さは加工機によって異なるので、加工機ごとに突き出し長さを変更する必要がある。なお、この突き出し長さは、加工機が変わってもせいぜい３〜４種類に分類することができる。本発明によれば、ネジ穴７を２個以上設けた位置決め部材４を回転させたり裏返したりすることによって、上記３〜４種類ある突き出し長さそれぞれに適応した位置に突き出し長さを制御することができる。したがって、上記図１の構成によって、刃物台９への切削工具１の取り付けに際して煩雑な切刃４の位置合わせ作業が簡単にできるとともに切刃３の位置ずれを抑制できて、作業効率および加工精度に優れる切削工具１となる。   Since the protruding length of the cutting tool 1 from the tool post 9 varies depending on the processing machine, it is necessary to change the protruding length for each processing machine. In addition, this protrusion length can be classified into 3-4 types at most even if a processing machine changes. According to the present invention, the protrusion length is controlled to a position suitable for each of the above three to four kinds of protrusion lengths by rotating or turning the positioning member 4 provided with two or more screw holes 7. Can do. Therefore, the configuration shown in FIG. 1 makes it possible to easily perform the complicated positioning operation of the cutting blade 4 when attaching the cutting tool 1 to the tool post 9, and to suppress the positional deviation of the cutting blade 3, thereby improving the work efficiency and processing accuracy. It becomes the cutting tool 1 which is excellent in.

Moreover, the main surface of the positioning member 4 is a rectangle which consists of a rectangle or a square . Further, the positioning member 4 has two screw holes 7 formed at an angle of 45 ° with respect to the side of the positioning member 7. It is desirable in that it is compatible with most processing machines.

また、取り付け部材４のネジ穴７の位置は図２の構成に限定されるものではなく、図３のように２個のネジ穴７が位置決め部材４の辺に対して平行な位置に形成されていてもよい。この構成に対応すべく、工具本体２のネジ穴８は３個形成される。なお、図２、３に
おいては、理解しやすくするために、位置決め部材７の各辺に便宜上Ａ，Ｂ，Ｃ，Ｄの記号を付与している。 Further, the position of the screw hole 7 of the attachment member 4 is not limited to the configuration shown in FIG. 2, and the two screw holes 7 are formed at positions parallel to the sides of the positioning member 4 as shown in FIG. 3. It may be. In order to correspond to this configuration, three screw holes 8 of the tool body 2 are formed. 2 and 3, symbols A, B, C, and D are given to each side of the positioning member 7 for convenience in order to facilitate understanding.

さらに、位置決め部材４は板状なので、隣り合う切削工具１，１同士が近接しても、位置決め部材４が障害になることなく、小型部品や精密部品を加工するような小型自動旋盤に用いる小さいくし形刃物台にも適用することができる。   Furthermore, since the positioning member 4 is plate-shaped, even if the adjacent cutting tools 1 and 1 are close to each other, the positioning member 4 does not become an obstacle, and is small used for a small automatic lathe for processing small parts and precision parts. It can also be applied to a comb tool post.

なお、本実施形態においては、切削工具１をくし形状の刃物台９に取り付ける場合を例に挙げて説明したが、複数の工具を放射状に配置し、旋回割り出しを行うタレット等の種々の刃物台に適用することができる。また、切削工具としてもこれに限定されるものではなく、ろう付けバイト等に適用することができる。さらに、切削工具に代えて、被削材を自動供給するために用いられるプルホルダ（株式会社アルプスツール社製：ＰＴ−７０）に転用することも考えられる。また、被削材を基準の突き出し量にするために用いられるプッシャに転用することも考えられる。この場合も同様に位置決め作業を短縮化することができる。   In the present embodiment, the case where the cutting tool 1 is attached to the comb-shaped tool rest 9 has been described as an example. However, various tool rests such as a turret in which a plurality of tools are arranged radially to perform swivel indexing are described. Can be applied to. Further, the cutting tool is not limited to this, and can be applied to a brazing tool or the like. Further, instead of the cutting tool, it is conceivable to divert it to a pull holder (manufactured by Alps Tool Co., Ltd .: PT-70) used for automatically supplying a work material. Moreover, it is also conceivable to divert the work material to a pusher used for making the reference protrusion amount. In this case as well, the positioning operation can be shortened.
