【０００７】[0007]
ホルダー体４の突条10の間に固定筒２の突片部７が位置するようにして固定筒 ２の内孔５にホルダー体４のテーパー筒９を嵌着し、被嵌筒13を回動せしめると 、突条10の先端面10'は突片部７の基端面７'に押圧され、従ってテーパー筒９は 引き込まれ、突条10の基端面が基筒12の先端面12'に当接し、該突条10は基筒12 の先端面12'と突片部７の基端面７'とでクランプされ、よって、ホルダー体４は 内孔５とテーパー筒９のテーパー作用及び突条10の前記被クランプ作用の２つの 作用で固定筒２に保持される。 The tapered cylinder 9 of the holder body 4 is fitted into the inner hole 5 of the fixed cylinder 2 so that the protruding piece portion 7 of the fixed cylinder 2 is located between the protrusions 10 of the holder body 4, and the fitted cylinder 13 is rotated. When moved, the tip end surface 10 ′ of the ridge 10 is pressed by the base end surface 7 ′ of the projecting piece portion 7, so that the taper cylinder 9 is retracted, and the base end surface of the ridge 10 becomes the tip end surface 12 ′ of the base cylinder 12. Abutting, the projection 10 is clamped by the tip end surface 12 ′ of the base tube 12 and the base end surface 7 ′ of the projecting piece portion 7, so that the holder body 4 is tapered by the inner hole 5 and the taper tube 9 and the projection piece. It is held in the fixed barrel 2 by two functions of the above-mentioned clamped function of 10.
【０００８】 ホルダー体４を固定筒２から外す際には被嵌筒13を回動せしめると、被嵌筒13 の先端面13'が受け体16の基端面を押圧する為基筒12の内孔５とテーパー筒９と のテーパー嵌合が容易に解放される。When the fitted tube 13 is rotated when the holder body 4 is detached from the fixed tube 2, the tip end surface 13 ′ of the fitted tube 13 presses the base end surface of the receiving body 16 so that the inside of the base tube 12 is pushed. The tapered fitting between the hole 5 and the tapered barrel 9 is easily released.
【０００９】[0009]
図面は本考案の一実施例を図示したもので以下に説明する。 The drawings illustrate one embodiment of the present invention and will be described below.
【００１０】 符号２は固定筒であって、工作機械の主軸１にテーパー嵌合されている。Reference numeral 2 is a fixed cylinder, which is taper-fitted to the spindle 1 of the machine tool.
【００１１】 この固定筒２は、後記する突条10の基端面を押圧する平坦先端面12'を形成し た基筒12に被嵌筒13を螺着したもので、基筒12の内孔５は先端側程拡開するテー パー孔に形成され、また、被嵌筒13の先端開口縁には２つの突片部７が対設され ている。The fixed cylinder 2 is formed by screwing a fitted cylinder 13 onto a base cylinder 12 having a flat tip surface 12 ′ that presses a base end surface of a protrusion 10 described later. 5 is formed in a taper hole that widens toward the tip side, and two projecting pieces 7 are provided opposite to each other at the tip opening edge of the fitted tube 13.
【００１２】 符号４はホルダー体であって、該ホルダー体４は、前記基筒12のテーパー孔と 合致するテーパー筒９が設けられ、このテーパー筒９の先端にはコレットチャッ ク14が嵌着され、更に被嵌体15が螺着されている。Reference numeral 4 is a holder body, and the holder body 4 is provided with a taper tube 9 that matches the taper hole of the base tube 12, and a collet chuck 14 is fitted to the tip of the taper tube 9. Further, the fitting body 15 is further screwed.
【００１３】 また、テーパー筒９の外周面には被嵌筒13の先端開口に嵌入し得る外径の２つ の突条10が形成され、この突条10の間のスペースは前記突片部７の周方向長さと ほぼ同一に設定されている。この突条10の先端面10'は前記突片部７の基端面７' に当接する当接面に形成されている。Further, on the outer peripheral surface of the tapered barrel 9, two protrusions 10 having an outer diameter that can be fitted into the tip opening of the fitted barrel 13 are formed, and the space between the protrusions 10 is the protrusion portion. It is set to be almost the same as the circumferential length of 7. The tip end surface 10 ′ of the protrusion 10 is formed as an abutment surface that abuts the base end surface 7 ′ of the protrusion piece 7.
【００１４】 符号17は押圧体，符号11はボール，符号８は偏平嵌入部，符号６は偏平孔であ る。Reference numeral 17 is a pressing body, reference numeral 11 is a ball, reference numeral 8 is a flat fitting portion, and reference numeral 6 is a flat hole.
【００１５】 本実施例は上記構成であるから、例えばドリルをコレットチャック14に保持せ しめたホルダー体４のテーパー筒９を固定筒２の内孔５に、突条10同志の間に該 固定筒２の突片部７が位置する状態で嵌着し、被嵌筒13を回動せしめると、突条 10の先端面10'は突片部７の基端面７'に押圧され、従って、テーパー筒９は引き 込まれ、突条10の基端面が基筒12の先端面12'に当接し、該突条10は基筒12の先 端面12'と突片部７の基端面７'とでクランプされる。Since the present embodiment has the above-described structure, for example, the tapered barrel 9 of the holder body 4 holding the drill on the collet chuck 14 is fixed to the inner hole 5 of the fixed barrel 2 between the ridges 10 of the same. When the protruding piece 7 of the tube 2 is fitted in the position and the fitted tube 13 is rotated, the tip end surface 10 ′ of the ridge 10 is pressed by the base end surface 7 ′ of the protruding piece 7, and therefore, The taper cylinder 9 is retracted, and the base end surface of the protrusion 10 abuts on the tip end surface 12 'of the base cylinder 12, and the protrusion 10 contacts the base end surface 12' of the base cylinder 12 and the base end surface 7'of the protrusion piece 7. It is clamped with.
【００１６】 従って、ホルダー体４は、この突条10の被クランプ作用及びテーパー筒９と基 筒12の内孔５とのテーパー作用（芯出しも確実に行える。）により確実に固定筒 ２に保持されることになる。Therefore, the holder body 4 is securely fixed to the fixed barrel 2 by the clamped action of the ridge 10 and the taper action of the tapered barrel 9 and the inner hole 5 of the base barrel 12 (centering can be reliably performed). Will be retained.
【００１７】 そして、基筒12の先端面12'と突条10の基端面が当接する構成である為、固定 筒２に対してのホルダー体４の取り付け時における軸方向のばらつきを抑制し得 ることになる。即ち、基筒12の先端面12'と突条10の基端面との当接が存しない とテーパー筒９が固定筒２の内孔５の中に入り込み過ぎたりすることが生じ得る が本実施例はこのような問題を確実に阻止し得ることになり、それだけ高精度な 作業が可能となる。Since the tip end surface 12 ′ of the base tube 12 and the base end surface of the ridge 10 are in contact with each other, it is possible to suppress variation in the axial direction when the holder body 4 is attached to the fixed tube 2. Will be. That is, if there is no contact between the tip end surface 12 ′ of the base tube 12 and the base end surface of the ridge 10, the tapered tube 9 may get into the inner hole 5 of the fixed tube 2 too much. The example can certainly prevent such a problem, and thus the work with high accuracy becomes possible.
【００１８】 また、固定筒２に対し、ホルダー体４を取り外すときは、同様に被嵌筒13を回 動せしめると、被嵌筒13の先端面13'が受け体16の基端面を押圧する為ホルダー 体４は固定筒２から容易に外れることになる。When the holder body 4 is detached from the fixed barrel 2, the fitted barrel 13 is also rotated, and the tip surface 13 ′ of the fitted barrel 13 presses the base end surface of the receiving body 16. Therefore, the holder body 4 can be easily removed from the fixed cylinder 2.
【００１９】 以上、ホルダー体４の固定筒２に対する着脱は、単に被嵌筒13を回動するだけ であるから非常に迅速に行えることになり、また、固定筒２とホルダー体４との 連結も前記した２つの作用により確実に行われることになる。As described above, attachment / detachment of the holder body 4 with respect to the fixed barrel 2 can be performed very quickly because the fitted barrel 13 is simply rotated, and the fixed barrel 2 and the holder body 4 are connected. Also, the above two actions will surely be performed.
【００２０】 従って、例えば、種々の工具をコレットチャック14に挾持させた数種のホルダ ー体４を予め用意しておくことで、工作・切削作業を非常に迅速に行い得ること になる。Therefore, for example, by preparing in advance several kinds of holder bodies 4 in which the collet chuck 14 holds various tools, the working / cutting work can be performed very quickly.
【００２１】 尚、本実施例は受け体16が存する為、突片部７同志の間から切削屑が内孔５内 に侵入することを防止でき（防塵効果）、このような点においても秀れた装置と なる。Since the receiver 16 is provided in the present embodiment, it is possible to prevent cutting chips from entering the inner hole 5 from between the projecting piece portions 7 (dustproof effect). It will be a device
【００２２】[0022]
本考案は上述のように構成したから、ホルダー体を固定筒に堅固に保持し得る とともに、ホルダー体と固定筒との脱着を迅速に行い得る秀れた工具保持装置と なる。 Since the present invention is configured as described above, it is an excellent tool holding device capable of firmly holding the holder body in the fixed cylinder and quickly detaching and attaching the holder body and the fixed cylinder.
