しかしながら、切削と研磨の切換えを、先端工具を交換して行うのでは、非常に厄介である。   However, it is very troublesome to switch between cutting and polishing by exchanging the tip tool.

本発明は、このような問題点に鑑み、切削と研磨の切換えを容易に行うことができる回転式動力工具及び回転式動力工具用の先端工具を提供することを課題とする。   In view of such problems, it is an object of the present invention to provide a rotary power tool and a tip tool for a rotary power tool that can be easily switched between cutting and polishing.

上記の課題は、先端工具に切削部と研磨部とが備えられ、所定の回転数又は所定範囲の回転数において、切削部と研磨部のいずれか一方がもう一方よりも相対的に半径線方向外方に突出した状態が形成され、それよりも大きな回転数において、遠心力により、前記もう一方が前記一方よりも相対的に半径線方向外方に突出した状態が形成されるようになされて、切削と研磨の切換えを行うことができるようになされていることを特徴とする回転式切削研磨動力工具によって解決される（第１発明）。   The above-described problem is that the cutting tool and the polishing unit are provided in the tip tool, and at a predetermined rotation number or a predetermined range of rotation number, either the cutting unit or the polishing unit is in the radial direction relative to the other. A state of projecting outward is formed, and at a higher rotational speed, a state of projecting the other relative to the radial direction relative to the other is formed by centrifugal force. The invention is solved by a rotary cutting and polishing power tool characterized in that switching between cutting and polishing can be performed (first invention).

この動力工具では、回転数を変化させることによって、先端工具を、切削用の先端工具にしたり、研磨用の先端工具にしたりすることができ、先端工具の交換の必要がなく、切削と研磨の切換えを容易に行うことができ、ひいては、作業効率の向上を図ることができる。   In this power tool, the tip tool can be changed to a cutting tool or a cutting tool by changing the number of revolutions, and there is no need to replace the tip tool. Switching can be easily performed, and as a result, work efficiency can be improved.

また、上記の課題は、切削部と研磨部とが備えられ、所定の回転数又は所定範囲の回転数において、切削部と研磨部のいずれか一方がもう一方よりも半径線方向外方に相対的に突出した状態が形成され、それよりも大きな回転数において、遠心力により、前記もう一方が前記一方よりも相対的に半径線方向外方に突出した状態が形成されるようになされて、切削と研磨の切換えを行うことができるようになされていることを特徴とする回転式動力工具用の切削研磨先端工具によって同様に解決される（第２発明）。   In addition, the above-described problem is provided with a cutting portion and a polishing portion, and at a predetermined rotation speed or a predetermined range of rotation speed, either the cutting portion or the polishing portion is relatively more radially outward than the other. A projecting state is formed, and at a higher rotational speed, a centrifugal force causes the other to project in a radially outward direction relative to the one, The same problem can be solved by a cutting / polishing tip tool for a rotary power tool characterized in that switching between cutting and polishing can be performed (second invention).

本発明の回転式動力工具及び回転式動力工具用の先端工具は、以上のとおりのものであるから、切削と研磨の切換えを容易に行うことができる。   Since the rotary power tool and the tip tool for the rotary power tool of the present invention are as described above, switching between cutting and polishing can be easily performed.

次に、本発明の実施最良形態を図面に基づいて説明する。   Next, the best mode for carrying out the present invention will be described with reference to the drawings.

図１〜図３に示す実施形態において、１は切削研磨先端工具であり、該切削研磨先端工具１は、図示しないインパクトレンチなどの回転式動力工具に着脱式で取り付けることができるようになされていて、図２（イ）（ロ）に示すように、先端工具本体２の基端部には、回転式動力工具と連結するための連結用軸部３が備えられている。   In the embodiment shown in FIGS. 1 to 3, reference numeral 1 denotes a cutting and polishing tip tool, and the cutting and polishing tip tool 1 can be detachably attached to a rotary power tool such as an impact wrench (not shown). As shown in FIGS. 2 (a) and 2 (b), the base end portion of the tip tool body 2 is provided with a connecting shaft portion 3 for connecting to a rotary power tool.

先端工具本体２は、外周部に複数本の切削用刃部４…を周方向に間隔的に備えた切削用ロッド部５を軸心位置に備え、該切削用ロッド部５には、切削用刃部４…間の位置において開口する周方向に複数本のスリット６…が備えられ、各スリット６内には、砥石などによる研磨部材７が出没可能に設けられている。   The tip tool body 2 includes a cutting rod portion 5 having a plurality of cutting blade portions 4 on the outer peripheral portion at intervals in the circumferential direction. The cutting rod portion 5 includes a cutting rod portion 5 for cutting. A plurality of slits 6 are provided in the circumferential direction opening at a position between the blade portions 4..., And a polishing member 7 such as a grindstone is provided in each slit 6 so as to appear and retract.

そして、各スリット６内に付勢手段としてのバネ８が組み込まれ、各研磨部材７は、バネ８の付勢力で、外方に突出することなくスリット６内に収容状態に保持されており、動力工具の回転駆動による遠心力が一定値を下回って小さいと、図１（イ）に示すように、バネ８の付勢力が遠心力に勝ち、スリット６内に後退した状態を保って、先端工具１を切削用先端工具に構成すると共に、動力工具の回転駆動による遠心力が一定値に以上に大きいと、図１（ロ）に示すように、遠心力が勝って、バネ８の付勢力に抗してスリット６から外方に突出し、先端工具１を研磨用先端工具に構成するようになされている。例えば、先端工具１は、動力工具の回転数が２０００ｒｐｍで切削用先端工具に構成され、４０００ｒｐｍで研磨用先端工具に構成されるようになされる。   Then, a spring 8 as a biasing means is incorporated in each slit 6, and each polishing member 7 is held in the slit 6 by the biasing force of the spring 8 without protruding outward, When the centrifugal force due to the rotational drive of the power tool is smaller than a certain value, the urging force of the spring 8 overcomes the centrifugal force and keeps the retracted state in the slit 6 as shown in FIG. When the tool 1 is configured as a cutting tip tool and the centrifugal force due to the rotational drive of the power tool is greater than a certain value, the centrifugal force wins and the urging force of the spring 8 as shown in FIG. Thus, the tip tool 1 projects outward from the slit 6 to constitute the tip tool for polishing. For example, the tip tool 1 is configured as a cutting tip tool when the rotational speed of the power tool is 2000 rpm, and is configured as a polishing tip tool at 4000 rpm.

上記の先端工具１は、図示しない回転式動力工具に連結接続して用いられ、図３（イ）に示すように、該動力工具を駆動して先端工具１を低い回転数で回転すると、先端工具１は、研磨部材７がスリット６内に後退した切削用先端工具を構成して加工対象物９の切削を行っていくことができ、切削を終えた後、図３（ロ）に示すように、該動力工具の出力を高めて先端工具１を高い回転数で回転すると、先端工具１は、研磨部材７がスリット６から外方に突出した研磨用先端工具となって加工対象物９の研磨を行っていくことができる。   The tip tool 1 is used by being connected to a rotary power tool (not shown), and when the power tool is driven to rotate the tip tool 1 at a low rotational speed as shown in FIG. The tool 1 can constitute a cutting tip tool in which the polishing member 7 is retracted into the slit 6 and can cut the workpiece 9. After the cutting is finished, as shown in FIG. Furthermore, when the output of the power tool is increased and the tip tool 1 is rotated at a high rotational speed, the tip tool 1 becomes a polishing tip tool in which the polishing member 7 protrudes outward from the slit 6 and the workpiece 9 Polishing can be performed.

このように、上記の先端工具１によれば、回転式動力工具の出力を代えて回転数を変化させるだけで、先端工具１を、切削用の先端工具にしたり、研磨用の先端工具にしたりすることができて、先端工具の交換の必要がなく、切削と研磨の切換えを容易に行うことができる。   Thus, according to the tip tool 1 described above, the tip tool 1 can be used as a cutting tip tool or a polishing tip tool simply by changing the rotational speed by changing the output of the rotary power tool. Therefore, there is no need to change the tip tool, and switching between cutting and polishing can be easily performed.

以上に、本発明の実施形態を示したが、本発明はこれに限られるものではなく、発明思想を逸脱しない範囲で各種の変更が可能である。例えば、上記の実施形態では、バネ８などの付勢手段を用いた場合を示したが、摩擦力などを利用して切削と研磨の切換えが行われるようになされていてもよく、その場合は、研磨のために遠心力で外方突出状態となった研磨部材を、動力工具の駆動停止後にスリット内に押し込んで切削用先端工具に戻す構造などになっていてもよい。   Although the embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications can be made without departing from the spirit of the invention. For example, in the above embodiment, the case where the biasing means such as the spring 8 is used is shown. However, switching between cutting and polishing may be performed using a frictional force, in which case The polishing member that has been protruded outward by centrifugal force for polishing may be configured to be pushed into the slit and returned to the cutting tip tool after the driving of the power tool is stopped.

また、上記の実施形態では、先端工具１が、低回転数で切削用先端工具となり、高回転数で研磨用先端工具となる場合を示したが、低回転数で研磨用先端工具となり、高回転数で切削用先端工具となるように構成されていてもよい。   In the above embodiment, the case where the tip tool 1 is a cutting tip tool at a low rotation number and a polishing tip tool at a high number of rotations is shown. You may be comprised so that it may become a front-end tool for cutting by rotation speed.

更に、上記の実施形態では、先端工具１が、汎用の回転式動力工具に接続して用いられる形式のものに構成されているが、専用の回転式切削研磨動力工具における先端工具として構成されていてもよい。また、本発明は、先端工具のほか、先端工具部を備えた回転式切削研磨動力工具を含む。   Further, in the above-described embodiment, the tip tool 1 is configured to be used by being connected to a general-purpose rotary power tool, but is configured as a tip tool in a dedicated rotary cutting and polishing power tool. May be. In addition to the tip tool, the present invention includes a rotary cutting and polishing power tool having a tip tool portion.
