- the X table 152 When both of the proximity sensors 157a are ON, the X table 152 is located in the non-interference area NIA, so the Y table positioning control section 194a of the control device 190 moves the Y table 172 to a predetermined Y table safe position (X table 152 is moved to a position where the Y table 172 does not interfere with the exterior cover 120 or the main shaft 140 (step S23).
- the X table positioning control section 192a of the control device 190 performs the origin return operation of the X table 152 (step S24). Specifically, the X-table positioning control unit 192a drives and controls the X-direction drive motor 154 to move the X-table 152 until the abutting portion 152b on the exterior cover side of the X-table 152 abuts against the cover-side stop member 156. . A position deviated by a predetermined amount from the position where the abutting portion 152b of the X table 152 abuts against the cover-side stop member 156 is the origin when the X table 152 moves in the X direction, which is set on the control device 190. .
- the X-table position detection unit 157 is also used for positioning the X-table 152 with respect to the X-direction rails 151 of the X-direction slide mechanism 150 .
- the Y-table positioning control section 194a which is the second table positioning control section, moves the X-table 152, which is the first table, to the non-interference area NIA in the second rail.
- the Y table 172 is slid on the Y direction rail 171 when positioning the Y table 172 with respect to the Y direction rail 171.
- the turret 180 Since the Y table 172 does not interfere with the spindle 140 or the external cover 120, which is a cover, even when performing positioning such as a return-to-origin operation, the turret 180, which is a tool rest, is positioned in the spindle direction with respect to the spindle 140. It is possible to reliably prevent the Y table 172 from interfering with the main shaft 140 and the outer cover 120 in a state of being retracted in the Z direction.
- the X table position detection unit 157 which is the first table position detection unit, is also used for positioning the X table 152 with respect to the X direction rail 151 of the X direction slide mechanism 150, which is the first slide mechanism. Since it is determined whether the X table 152 is in the non-interference area NIA or in the interference area IA when the origin return operation is performed for the X table 152, when the origin return operation is performed for the X table 152 , even if the X table 152 is positioned in the interference area IA, the Y table 172 is moved to a position where the Y table 172 does not interfere with the spindle 140 or the external cover 120, and the origin return operation for the X table 152 is continued. It is possible to prevent the Y table 172 from interfering with the spindle 140 or the external cover 120 during the return-to-origin operation for the X table 152 .
- the X-table position detection unit 157 has the proximity sensor 157a that detects the X-table 152 using the boundary between the non-interference area NIA and the interference area IA on the X-direction rail 151 as the detection position. can detect the position of the X table 152 with respect to the X-direction rail 151 by detecting the X table 152.

Description
そして、この工作機械の加工用スライドには、バイトのような工具が取り付けられるタレット(刃物台)が設けられている。
そこで、定期的に加工用スライドを工作機械の基準点(原点)へ移動させる原点復帰と呼ばれる動作が必要となっている。
したがって、原点復帰中に、タレットを主軸に対してZ軸方向に退避させたとしても、加工用スライドがワークを保持する主軸や工作機械の機能部品を覆うカバーと干渉する虞がある。
すなわち、請求項1に係る発明の工作機械によれば、第2テーブル位置決め制御部が、第1テーブルを無干渉領域に位置させた状態で、第2レールに対する第2テーブルの位置決めを行うことにより、第2レールに対する第2テーブルの位置決めを行う際に、第2テーブルを第2レール上で摺動させても第2テーブルが主軸またはカバーと干渉しないため、原点復帰動作のような位置決めを行う際であっても、刃物台を主軸に対して主軸方向に退避させた状態で加工用テーブルである第2テーブルが主軸やカバーと干渉することを確実に防止することができる。
例えば、本発明の工作機械における第2の方向は、主軸方向および第1の方向と交差していれば如何なる方向であってもよく、水平面に対して傾斜した方向であってもよいし、水平面に対して垂直方向であってもよい。
まず、図1乃至図6に基づいて、工作機械100の概要について説明する。
図1は本発明の第1実施例である工作機械の正面図であり、図2は図1に示す工作機械のカバーを一部除去した状態の正面図であり、図3は図1に示す工作機械のシステム構成図であり、図4は図2のIV-IV線に沿って見た工作機械の要部側面断面図であり、図5は図2のV-V線に沿って見た工作機械の要部側面断面図であり、図6は図5のVI-VI線に沿って見た工作機械の要部断面図である。
工作機械100は、自動旋盤であり、図1に示すように、床面Fに載置されるベッド110と、外観を形成する直方体状の外観カバー(カバー)120と、工作機械100の使用者が工作機械100を操作するための操作盤130とを備えている。
以下、床面Fに対する垂直方向を工作機械100の上下方向とし、平面視におけるベッド110の長手方向を工作機械100の左右方向(Z方向)とし、平面視におけるベッド110の短手方向を工作機械100の前後方向とする。
また、ベッド110は、図4に示すように、側面視で後方から前方に向かって下り傾斜している傾斜基面111を有している。
以下、この水平面に対して傾斜した傾斜基面111の傾斜方向をX方向という。
このスライドドア121を開くことで、工作機械100の使用者はワークの加工が行われる加工室PR(図2参照)内にアクセスすることができる。
また、外観カバー120の左側上方には、図1および図4に示すように、操作盤130を収容するために後方かつ下方に向かって凹んだ操作盤収容凹部122が形成されている。
さらに、外観カバー120の左側下方は、図4に示すように、前方に向けて膨出している。
工作機械100は、図2および図3に示すように、さらに、ベッド110の傾斜基面111に載置されてワークを把持する主軸140およびX方向スライド機構(第1スライド機構)150と、このX方向スライド機構150に固定されたZ方向スライド機構160と、このZ方向スライド機構160に固定されたY方向スライド機構(第2スライド機構)170と、このY方向スライド機構170に設けられたタレット(刃物台)180と、工作機械100の動作を制御する制御装置190とを備えている。
そして、主軸140とX方向スライド機構150とY方向スライド機構170とタレット180とは、図4等に示すように、外観カバー120によって覆われている。
主軸140は、Z方向(本発明における「主軸方向」)に延びており、X方向スライド機構150を左右方向に跨いでベッド110の傾斜基面111に固定される主軸台141と、この主軸台141に載置される主軸本体142とから構成されている。
X方向スライド機構150は、図4乃至図6に示すように、ベッド110の傾斜基面111に固定されるX方向レール(第1レール)151と、このX方向レール151に沿って摺動自在な金属製のXテーブル(第1テーブル)152と、このXテーブル152を駆動させるXテーブル駆動軸153と、制御装置190からの制御に基づきXテーブル駆動軸153を回転させるX方向駆動モーター154と、Xテーブル152の摺動端となる主軸側止め部材155およびカバー側止め部材156と、X方向レール151に対するXテーブル152の位置を検出するXテーブル位置検出ユニット(第1テーブル位置検出ユニット)157とを有している。
すなわち、本実施例においてX方向レール151は、図2に示すように主軸140の延びる方向であるZ方向と直交(交差)していると共に、図4に示すように水平面に対して傾斜している。
また、Xテーブル152の摺動範囲は、X方向スライド機構150の主軸140側に設けられた主軸側止め部材155およびX方向スライド機構150の外観カバー120側に設けられたカバー側止め部材156により物理的に規制されている。
さらに、外観カバー120と対向するXテーブル152のXテーブル基面152aには、Z方向スライド機構160を載置するためのZ方向に延びる凹領域152a1が形成されている。
また、近接センサー157aは、図6に示すようにベッド110の傾斜基面111にブラケット157bを介して設けられている。
そして、この近接センサー157aは、図5に示すように主軸140側に設けられた主軸側近接センサー157a1および外観カバー120側に設けられたカバー側近接センサー157a2の2つから構成されている。
Z方向スライド機構160は、図4および図5に示すように、Xテーブル152に対して摺動自在なZテーブル161と、このZテーブル161を駆動させるZテーブル駆動軸162と、制御装置190からの制御に基づきZテーブル駆動軸162を回転させるZ方向駆動モーター(不図示)とを有している。
このように構成されたZ方向スライド機構160は、制御装置190からの制御に基づき、Zテーブル161がXテーブル152に対してZ方向に摺動自在となっている。
Y方向スライド機構170は、図4および図5に示すように、Z方向スライド機構160のZテーブル161に固定されるY方向レール(第2レール)171と、このY方向レール171に沿って摺動自在なYテーブル(第2テーブル)172と、このYテーブル172を駆動させるYテーブル駆動軸173と、制御装置190からの制御に基づきYテーブル駆動軸173を回転させるY方向駆動モーター(不図示)とを有している。
すなわち、本実施例においてY方向レール171は、図4等に示すようにX方向スライド機構150のXテーブル152上に設けられてZ方向およびX方向と交差するY方向に延在している。
また、Yテーブル172の摺動範囲は、Y方向レール171の外観カバー側に設けられたカバー側突き当て部171aおよびY方向レール171の主軸側に設けられた主軸側突き当て部171bにより物理的に規制されている。
タレット180は、図3等に示すように、Y方向スライド機構170のYテーブル172に載置されてワークを加工する工具(不図示)を保持している。
タレット180はYテーブル172に載置されていると共にYテーブル172はZテーブル161を介してXテーブル152に載置されているため、タレット180は主軸140および外観カバー120に対して接近自在となっている。
制御装置190は、少なくとも、主軸140と、X方向スライド機構150と、Y方向スライド機構170とを駆動制御する制御装置であり、図3に示すように、主軸140を駆動制御する主軸制御ユニット191と、X方向スライド機構150を駆動制御するX方向スライド機構制御ユニット192と、Z方向スライド機構160を駆動制御するZ方向スライド機構制御ユニット193と、Y方向スライド機構170を駆動制御するY方向スライド機構制御ユニット194とを有している。
X方向スライド機構制御ユニット192は、X方向駆動モーター154を駆動制御してX方向レール151に対するXテーブル152の位置を所定位置に定めるXテーブル位置決め制御部(第1テーブル位置決め制御部)192aを有している。
Y方向スライド機構制御ユニット194は、Y方向駆動モーターを駆動制御してY方向レール171に対するYテーブル172の位置を所定位置に定めるYテーブル位置決め制御部(第2テーブル位置決め制御部)194aを有している。
次に、このように構成された工作機械100におけるYテーブル172の挙動について、図7A乃至図8Cに基づいて、更に詳しく説明する。
図7AはYテーブルが主軸と干渉した状態を示す要部側面断面図であり、図7BはYテーブルがカバーと干渉した状態を示す要部側面断面図であり、図8Aは図7Aに対応するXテーブルの位置を示す模式図であり、図8Bは図7Bに対応するXテーブルの位置を示す模式図であり、図8Cは図4に対応するXテーブルの位置を示す模式図である。
具体的には、図7Aおよび図8Aに示すようなXテーブル152のX方向の位置であれば、これらの図に示すように、Yテーブル172のY方向の位置次第でYテーブル172が主軸140の主軸台141や主軸本体142と干渉してしまう。
また、図7Bおよび図8Bに示すようなXテーブル152のX方向の位置であれば、これらの図に示すように、Yテーブル172のY方向の位置次第でYテーブル172が外観カバー120と干渉してしまう。
一方、図4および図8Cに示すようなXテーブル152のX方向の位置であれば、Yテーブル172のY方向の位置が如何なる位置であっても、Yテーブル172が外観カバー120や主軸140と干渉することがない。
すなわち、干渉領域IAはYテーブル172が主軸140と干渉しうる主軸干渉領域IAsとYテーブル172が外観カバー120と干渉しうるカバー干渉領域IAcとから形成され、無干渉領域NIAは主軸干渉領域IAsとカバー干渉領域IAcとの間に形成されていることになる。
すなわち、主軸側近接センサー157a1はX方向レール151の主軸干渉領域IAsと無干渉領域NIAとの境界を検出位置とし、カバー側近接センサー157a2はX方向レール151のカバー干渉領域IAcと無干渉領域NIAとの境界を検出位置とするように設けられている。
さらに換言すると、近接センサー157aがノーマルオープン型であることから、Xテーブル152が無干渉領域NIAに位置しているとき、主軸側近接センサー157a1およびカバー側近接センサー157a2はONになり、Xテーブル152が干渉領域IAに位置しているとき、主軸側近接センサー157a1またはカバー側近接センサー157a2の一方がONとなり、他方がOFFとなる。
次に、図1に示す工作機械における原点復帰動作のフローを示すフローチャートである図9に基づき、Yテーブル172をZ方向に動かしてタレット180を主軸140に対してZ方向に退避させた後の工作機械100における原点復帰動作の一例を説明する。
はじめに、制御装置190は、Xテーブル位置検出ユニット157によりXテーブル152が無干渉領域NIAまたは干渉領域IAのいずれかの領域に位置しているかを検出する。
近接センサー157aがいずれもOFFである場合、近接センサー157aが2つとも故障しているとして、原点復帰動作を行わない。
近接センサー157aがいずれもONではない場合、Xテーブル152がカバー干渉領域IAcまたは主軸干渉領域IAsに位置しているため、Xテーブル152を無干渉領域NIAまで移動させる(ステップS12)。
具体的には、Yテーブル位置決め制御部194aは、Y方向駆動モーターを駆動制御してYテーブル172の外観カバー側の突き当て部172a(図4参照)がY方向レール171に設けられたカバー側突き当て部171a(図4参照)に突き当たるまでYテーブル172を移動させる。
このYテーブル172の突き当て部172aがY方向レール171のカバー側突き当て部171aに当接する位置から所定量ズレた位置が、制御装置190上で設定されるYテーブル172がY方向への移動する際の原点となる。
このようにしてYテーブル172の原点復帰動作が終了した後、制御装置190は、再度、Xテーブル位置検出ユニット157によりXテーブル152が無干渉領域NIAまたは干渉領域IAのいずれかの領域に位置しているかを検出する。
近接センサー157aがいずれもOFFである場合、近接センサー157aが2つとも故障しているとして、原点復帰動作を行わない。
近接センサー157aがいずれもONではない場合、Xテーブル152がカバー干渉領域IAcまたは主軸干渉領域IAsに位置しているため、Xテーブル152を無干渉領域NIAまで移動させる(ステップS22)。
具体的には、Xテーブル位置決め制御部192aは、X方向駆動モーター154を駆動制御してXテーブル152の外観カバー側の突き当て部152bがカバー側止め部材156に突き当たるまでXテーブル152を移動させる。
このXテーブル152の突き当て部152bがカバー側止め部材156に当接する位置から所定量ズレた位置が、制御装置190上で設定されるXテーブル152がX方向への移動する際の原点となる。
以上説明した工作機械100によれば、第2テーブル位置決め制御部であるYテーブル位置決め制御部194aが、第1テーブルであるXテーブル152を無干渉領域NIAに位置させた状態で、第2レールであるY方向レール171に対する第2テーブルであるYテーブル172の位置決めを行うことにより、Y方向レール171に対するYテーブル172の位置決めを行う際に、Yテーブル172をY方向レール171上で摺動させてもYテーブル172が主軸140またはカバーである外観カバー120と干渉しないため、原点復帰動作のような位置決めを行う際であっても、刃物台であるタレット180を主軸140に対して主軸方向であるZ方向に退避させた状態でYテーブル172が主軸140や外観カバー120と干渉することを確実に防止することができる。
