しかし、前述した従来の冷却用流体による冷却では、ノズルの先端を加工部と 工具の刃先部とに接近させないと効率のよい冷却ができず、ノズルの先端を加工 部と工具の刃先部との微小な隙間に接近させて冷却すると、加工中に切削の流れ によってノズルが押されて偏向し、ノズルから噴射する冷却用流体の噴射方向が ずれて加工部と工具の刃先部に冷却用流体が充分に供給されなくなり、とくに無 人機などによる長時間加工の場合には、冷却用流体の供給なしに加工を行い、工 具の刃先部の摩擦を増大させると共に、加工品の品質不良が生ずるという問題点 があった。 However, with the above-described conventional cooling fluid, efficient cooling cannot be achieved unless the tip of the nozzle is brought close to the working part and the cutting edge of the tool, and the tip of the nozzle is cut between the working part and the cutting edge of the tool. When cooling is performed by approaching a minute gap, the nozzle is pushed and deflected by the cutting flow during machining, the direction of the cooling fluid jetted from the nozzle shifts, and the cooling fluid flows between the machining part and the cutting edge of the tool. Insufficient supply, especially in the case of long-time machining by unmanned machines, machining is performed without supplying the cooling fluid, increasing the friction of the cutting edge of the tool and causing poor product quality. There was a problem.
【０００５】 この考案は、前述した問題点を解決して、加工部と工具の刃先部とを効率よく 確実に切削液などの冷却用流体によって冷却でき、また、長時間加工の場合でも 前記流体の供給位置がずれない冷却ができ、工具の刃部の摩擦を少なくし、不良 品の発生を防止できるようにした、工具ホルダーを提供することを目的としてい る。The present invention solves the above-mentioned problems, and can efficiently and reliably cool the working portion and the cutting edge portion of the tool with a cooling fluid such as cutting fluid, and even in the case of long-time machining, the fluid It is an object of the present invention to provide a tool holder that can perform cooling without shifting the supply position of the tool, reduce friction of the blade part of the tool, and prevent defective products.

この考案による工具ホルダーは、孔ぐりバイト，孔あけドリルなどの工具のシ ャンク部を工具保持孔に嵌合保持させ、装着部を工作機械の刃物台などに装着し 、前記工具を回転させつつ前進させて工作物に孔ぐり，孔あけなどの加工を行い 、この加工時に、冷却用流体の供給源から切削液などの冷却用流体を流体通路を 経て噴射用溝に圧送し、噴射用溝と工具のシャンク部とによって構成された流体 通路に通し、工具ホルダーの先端面から軸方向に沿って冷却用流体を噴射し、工 作物の加工部と工具の刃先部とを、これらに接近した位置からの冷却用流体の噴 射によって冷却するものである。 In the tool holder according to the present invention, the shank portion of a tool such as a boring tool or a drill is fitted and held in the tool holding hole, and the mounting portion is mounted on a tool rest of a machine tool, while rotating the tool. Machining such as boring and boring is performed by advancing the workpiece.During this machining, cooling fluid such as cutting fluid is pressure-fed to the injection groove through the fluid passage from the cooling fluid supply source, and the injection groove is formed.

Cooling is performed by spraying a cooling fluid from a position.
【０００８】 そして、冷却用流体は、工具ホルダーの工具保持孔の孔壁に軸方向に沿って形 成したことにより、噴射方向がずれることがなく、近接した位置からの噴射によ って前記加工部と刃先部とに冷却用流体を当てて、これらを冷却するので、少量 の前記流体で効率のよい確実な冷却ができる。したがって、無人機などによる長 時間加工を行っても、冷却用流体が前記加工部と刃先部から外れないことにより 、この刃先部が充分に冷却されて摩擦しにくく、摩擦した刃先部での加工に起因 する不良品の発生もなくなる。Since the cooling fluid is formed along the axial direction in the hole wall of the tool holding hole of the tool holder, the jetting direction does not shift and the cooling fluid is jetted from a close position. Since a cooling fluid is applied to the working portion and the cutting edge portion to cool them, efficient and reliable cooling can be performed with a small amount of the fluid. Therefore, even if long-time machining with an unmanned machine etc., the cooling fluid does not come off from the machining part and the cutting edge part, so that this cutting edge part is sufficiently cooled and does not easily rub, and machining at the rubbed cutting edge part The generation of defective products due to

この考案による工具ホルダーは、孔ぐりバイト，孔あけドリルなどの工具のシ ャンク部を工具保持孔に嵌合保持させ、装着部を工作機械の刃物台などに装着し 、前記工具を回転させつつ前進させて工作物に孔ぐり，孔あけなどの加工を行い 、この加工時に、冷却用流体の供給源から切削液などの冷却用流体を流体通路を 経て噴射用溝に圧送し、噴射用溝と工具のシャンク部とによって構成された流体 通路に通し、工具ホルダーの先端面から軸方向に沿って冷却用流体を噴射し、工 作物の加工部と工具の刃先部とを、これらに接近した位置からの冷却用流体の噴 射によって冷却するものである。 In the tool holder according to the present invention, the shank portion of a tool such as a boring tool or a drill is fitted and held in the tool holding hole, and the mounting portion is mounted on a tool rest of a machine tool, while rotating the tool. Machining such as boring and boring is performed by advancing the workpiece.During this machining, cooling fluid such as cutting fluid is pressure-fed to the injection groove through the fluid passage from the cooling fluid supply source, and the injection groove is formed. And a shank part of the tool are passed through a fluid passage, and a cooling fluid is ejected from the tip surface of the tool holder along the axial direction to bring the machined part of the workpiece and the cutting edge of the tool close to them. Cooling is performed by spraying a cooling fluid from a position.
【０００８】 そして、冷却用流体は、工具ホルダーの工具保持孔の孔壁に軸方向に沿って形 成したことにより、噴射方向がずれることがなく、近接した位置からの噴射によ って前記加工部と刃先部とに冷却用流体を当てて、これらを冷却するので、少量 の前記流体で効率のよい確実な冷却ができる。したがって、無人機などによる長 時間加工を行っても、冷却用流体が前記加工部と刃先部から外れないことにより 、この刃先部が充分に冷却されて摩耗しにくく、摩耗した刃先部での加工に起因 する不良品の発生もなくなる。Since the cooling fluid is formed along the axial direction in the hole wall of the tool holding hole of the tool holder, the jetting direction does not shift and the cooling fluid is jetted from a close position. Since a cooling fluid is applied to the working portion and the cutting edge portion to cool them, efficient and reliable cooling can be performed with a small amount of the fluid. Therefore, even if the long time working due drone, by cooling fluid does not come off from the working portion and the cutting edge, less likely to wear the cutting edge is sufficiently cooled, with cutting edges that wear There is no generation of defective products due to processing.
