Abstract
Description
また、タレット刃物台に装着した工具によりワークを加工する際に、前記工具が装着されるタレットの工具装着部にクーラントを供給し、該工具装着部から工具によるワークの加工部位にクーラントを供給することが一般的に行われている(例えば特許文献2参照)。
上記クーラント供給パイプは内部をクーラントが流通するため、クーラント供給パイプが挿入される中間軸の中心部分を空間として有効利用することができないという欠点がある。また、クーラント供給パイプは、最も内側の軸内に挿入する必要があることから、最も小径の軸を中空にする必要がある。
この構成によれば、筒体と中間軸との間をクーラントが流通するため、筒体が挿入される中間軸の中心部分を空間として有効利用することができる。このため、中間軸の中心に、例えばタレットに装着される回転工具の駆動軸を設けることができるとともに、駆動軸として中実軸を用いることができる。また、クーラント供給管等を挿入する必要がなく、タレットの工具装着部に供給されるクーラントの流通路を簡単に形成することができる。
連通路を中間軸に形成することにより、駆動軸の先端近傍に他の回転軸等の構造部材が配置されていても、前記流通路を流通するクーラントを容易に案内流路に送出することが可能になる。これにより前記中間軸に、前記回転工具に駆動力を伝達する伝達軸を回転自在に設け、該伝達軸をタレット内の駆動軸の一端に配置することができる。
また、本発明のクーラント供給構造では、軸中心部にクーラント供給管を通してクーラントを供給する場合よりもクーラント流通孔の断面積を増大させることができ、多量のクーラントを流通させることが可能になる。
さらに、連通路を設けることで、駆動軸の先端近傍に他の回転軸や移動体その他の構造部材が配置されているような場合でも、所定の工具装着部にクーラントを供給することができる。
図1,2は、本発明のクーラント供給構造の一実施形態にかかり、図1はこの実施形態におけるタレット刃物台の構成を説明する正面断面図、図2は、図1のタレット刃物台におけるタレットの側面断面図である。なお、以下の説明では、図1及び図2の紙面の上方を「上」と記載し、同下方を「下」と記載する。
このタレット刃物台1は、刃物台本体11と、この刃物台本体11に割り出し回転自在に支持されるタレット12とを備える。
タレット12は、周面に形成された複数の工具装着部の各々に工具を装着することができ、割り出し回転の中心が旋回軸15の回転軸線上に位置するように、旋回軸15の上端に取り付けられる。前記タレット12側と刃物台本体11側との間には、タレット12を所定の旋回角度位置に位置決めして固定する位置決め手段11bが設けられている。
前記タレット12の上部には、タレット12の割り出し回転中心から工具装着部のそれぞれに向けて放射状に伸びる複数の案内流路26が形成されている。この案内流路26は、工具装着部に装着された工具Tのクーラント孔Tbに連通することができる。案内流路26の一端は、タレット12と中間軸19の上端とが摺接する摺接面に開口している。
例えば、上記の説明では、タレット12に回転工具が水平に装着される場合を例に挙げて説明したが、回転工具を垂直方向又は斜め方向に装着する他のタレット12にも本発明の適用は可能である。
また、上記の説明で第一のクーラント流通路24は筒体23と中間軸19との間に設けられた隙間から構成されるものとしたが、第一のクーラント流通路24はクーラントの流通ができればよく、隙間に限らず一本又は複数本の溝から構成されていてもよい。
また、本発明のクーラント供給構造では、軸中心に配置したクーラント供給管を用いる場合より多量のクーラントを流通させることが可能になるため、上記のように一つのタレットの一つの工具にクーラントを供給する場合に限らず、例えば、一つのタレットに装着した複数の工具で同時に複数のワークを加工する場合や、複数のタレットに装着した複数の工具でワークを加工する場合にも、一つのタレットの単一のクーラント供給構造を通して前記複数の工具に十分な量のクーラントを供給することが可能になる。
