Abstract
Description
上述した特許文献1、2に示されたクランプ機構は、いずれも剛性の低いものであって、アングルツールによる重切削に耐える能力は小さい。
本発明の目的は、立形マシニングセンタに付設して強力な5面加工を達成することができる5面加工用アングルツールホルダを提供するものである。
そして、本発明のアングルツールホルダは、立形マシニングセンタの主軸に挿入されるシャンクと、シャンクとアングルツールを回転自在に支持して内部にシャンクの駆動力を直交する方向に変換してアングルツールに伝達する伝動機構を備えるハウジングと、ハウジングに連結されるアームと、アーム上に設けられて5面加工用アタッチメントユニットの4基のコレットチャックのうちの3基のコレットチャックに把持される3本のプルスタッドボルトを備えるものである。
全体を符号1で示す立形マシニングセンタは、ベース10上にX軸方向に移動するテーブル20を有する。
ベース10上には門形のコラム30が立設され、門形のコラム30の前面に設けられたガイドレールに支持されたサドル40がY軸方向に移動する。
ベース10上には、ブラケット410がとりつけられ、ツールマガジン400が装備される。ツールマガジン400には、各種の交換工具T1が格納されていて、ATCアーム420は、主軸70に対して必要な工具を交換自在に供給する。
主軸ヘッド50の下端部には円筒形状の主軸ハウジング60が突出しており、主軸70を回転自在に支持している。
5面加工アタッチメントユニット100は、主軸ハウジング60に嵌装されて主軸ヘッド50の下端部に固定されるリング型シリンダ部材110を有し、クランプユニット130はリング型シリンダ部材110内のリング型ピストン120に直結されて昇降動する。
クランプユニット130の下面には円周上に4基のコレットチャック140が装備される。
後述する態様によって、プルスタッドボルト270がクランプユニット130のコレットチャック140にクランプされたときには、アングルツールホルダ200の回転を規制して切削抵抗を受ける。プルスタッドボルト270がアンクランプ時には、アーム250はシャンク210とともに旋回動して4個のコレットチャック140の位置に割り出される。
この状態では、アングルカッタ220は加工可能な状態となる。
5面加工アタッチメントユニット100は、リング型シリンダ部材110を有し、リング型シリンダ部材110はボルト112により主軸ヘッド側に固定される。リング型シリンダ部材110内には油圧室114が設けられ、リング形状のピストン120が摺動自在に嵌装される。油圧室114にはピストン120を作動するための油圧ポート116a、116bが連通される。
コレットチャック140は本体150内に油圧室152を有し、油圧室152内にピストン142が摺動自在に挿入される。
ピストン142は爪144を開閉操作する。油圧室152に連通するポート154a、154bが形成される。
この作動中には、ピストン142は上方へ付勢されていて、爪144は閉じている。
プルスタッドボルト270に対向するコレットチャック140のピストン142は油圧により下方へ付勢され、爪144を開く。
コレットチャック140はアーム250のプルスタッドボルト270を受け入れる。
レバー260の内端部262は、シャフト212の切欠部との係合を解く。
この状態では、アングルツールホルダ200のアーム250は5面加工アタッチメントユニット100のクランプユニット130に確実に把持される。
シャンク210と一体のシャフト212は、主軸側から伝達される動力によりアングルカッタ220を駆動して、ワークに加工を施す。
レバー260は、シャフト212と切り離されており、干渉を生ずることは防止される。
アーム250の有底の穴254には、シャフト280が挿入され、ボルト282により固定されている。シャフト280の上端にはプルスタッドボルト270がねじ部272を利用して立設される。
レバー260は、シャフト280の外周部に嵌合される内径部264を有し、シャフト280に摺動自在に支持される。レバー260の内端部262の近傍には穴が設けられ、アーム250に立設された突起252に差し込まれる。
レバー260はスプリング266により、アーム250から離れる方向に付勢され、レバー260の端部262はシャフト212の切欠部に係合されて割り出しが行なわれる。
また、4基のコレットチャックのうち、アングルツールの把持に関与しない3基のコレットチャックはその爪を閉じた状態に保つ。
5面加工アタッチメントユニット100は主軸に装備されるために、加工時に切削液や切粉等が噴霧する厳しい環境に露出される。
そこで使用されない3基のコレットチャック140の開口部からの異物の浸入を防止する装置を備えることが望ましい。
全体を符号500で示すアングルツールホルダは、本機の主軸に挿入されるシャンク510を有し、シャンク510の回転はハウジング540内の歯車伝動機構等を介して駆動軸が直角方向に変更されてアングルカッタ520を駆動する。
ハウジング540に連結されるアーム550は3本のプルスタッドボルト570を備える。3本のプルスタッドボルト570は90度毎に配置されており、5面加工アタッチメントユニットに配置される4基のコレットチャックのうちの3基のコレットチャックにより同時にクランプされる。中央に配置されるプルスタッドボルト570のアーム550上には、アングルツールホルダ500を割り出す際に用いるレバー560が設けられる。このレバー560の構造と機能は先に説明したものと同様である。
このアングルツールホルダ500は前述したアングルツールホルダ200と同様にATCアーム420によりマガジンから主軸に自動交換することができる。
5面加工用アタッチメントユニット100は、円周上に4基のコレットチャック140を有する。本発明のアングルツールホルダ500はアーム550上に3本のプルスタッドボルト570を有するので、90度毎の角度位置を変更してクランプすることができる。
アングルツールホルダ500を図2の(b)に示す方向に装着し、ワークW1の側面WBの加工を行う。
アングルツールホルダ500は3本のプルスタッドボルト570が3基のコレットチャック140で5面加工用アタッチメントユニット100に把持されるので、剛性が高く、ワークW1の側面WBを重切削することができる。
アングルツールホルダ600は、アーム650に3本のプルスタッドボルト670を有し、5面加工アタッチメントユニット100の4基のコレットチャック140のうちの3基のコレットチャックにクランプされる。
このアングルツールホルダ600はアングルツール620の刃先位置が主軸70の中心軸線より突出した位置にくるような突出しの長いアングルツール620を備えたものである。
このアングルツールホルダは、5面加工アタッチメントユニットの4基のコレットチャックのうち3基のコレットチャックでクランプするので、次のメリットがある。
(1)あえて1ヶ所のコレットチャックをクランプに用いなかった事で、側面加工時にワークと機械の干渉が避けられるため、深い加工ができる。
(2)一般に用いられるアングルツールホルダの1点クランプに対して本発明の高剛性アングルツールホルダは3倍の力でクランプできるので、より重切削が可能になる。
(3)3点クランプとした事で、標準のATCアームで把握することが可能になる。
