Description

複合加工機Multi-tasking machine
　本発明は、複数の装置により行われる複数の作業について空間を分けるための分離シャッタを備えた複合加工機に関する。 The present invention relates to a multi-tasking machine equipped with a separation shutter for separating spaces for a plurality of operations performed by a plurality of devices.
　工作機械では、省スペースやコンパクト化を実現するためにスラント型のベッドが採用され、そのベッドは前側が傾斜した形状をしている。下記特許文献１にもそうしたベッドの工作機械が開示されている。この工作機械は、左右に対向する主軸台が同一軸線上に配置された複合加工機であり、それぞれの主軸台にはチャックが設けられている。左側の主軸台はベッドに固定され、右側の主軸台は同一軸上の移動が可能になっている。ベッドは前側に低くなるよう傾斜したスラント型であり、機体後方向側には複合型刃物台が水平移動するよう構成されている。左右の主軸台の手前側下方には加工軸方向に移動可能なタレット刃物台が配置されている。そして、主軸に把持されたワークがタレットや複合型刃物台の工具によって加工が行われる。 Slant-type beds are used in machine tools to save space and make them more compact, and the bed has a slanted front side. Patent Document 1 listed below also discloses such a bed machine tool. This machine tool is a multi-tasking machine in which left and right headstocks are arranged on the same axis, and each headstock is provided with a chuck. The headstock on the left side is fixed to the bed, and the headstock on the right side can move on the same axis. The bed is a slant type that slopes lower toward the front, and a composite tool rest is configured to move horizontally toward the rear of the fuselage. A turret tool rest movable in the direction of the machining axis is arranged below the front side of the left and right headstocks. The workpiece gripped by the spindle is then machined by the tools of the turret and compound tool rest.

　複合加工機では、前述したように左右の主軸台に把持されたワークに対し、タレットや複合型刃物台の工具による複数の加工が行われる。そのため、複数の作業部での加工が一つの加工室内で行われると、一方の主軸台から飛び散る切粉やクーラントが他方の主軸台のチャックやワーク、或いはタレットの工具に付着してしまい、それによって加工精度を低下させてしまうことがある。そこで、複合加工機では各作業部での加工が仕切られた別々の空間で行われることが好ましいが、前記従来例には自動工具交換装置（ＡＴＣ）と複合型刃物台との間を仕切るシャッタしか存在しなかった。従って、機内を左右の幅方向に分離した別々の加工室を構成するシャッタが必要であるが、前面側が傾斜するスラント型のベッドでは傾斜部分までも遮断することが難しかった。 As mentioned above, in a multitasking machine, multiple machining operations are performed on the workpiece gripped by the left and right headstocks using the tools of the turret and compound tool post. Therefore, when machining is performed in a single machining chamber in multiple working areas, chips and coolant flying off from one headstock may adhere to the chuck or workpiece in the other headstock, or to the tools in the turret. This may reduce machining accuracy. Therefore, in a multitasking machine, it is preferable that the processing in each work section be performed in separate partitioned spaces, but in the conventional example, there is a shutter that partitions between the automatic tool changer (ATC) and the complex tool rest. only existed. Therefore, a shutter is required to separate the inside of the machine into left and right widthwise separate processing chambers, but with a slant bed with an inclined front side, it is difficult to close off even the inclined portion.
　そこで、本発明は、かかる課題を解決すべく、複数の作業部について空間を分けるための分離シャッタを備えた複合加工機を提供することを目的とする。 Therefore, in order to solve this problem, it is an object of the present invention to provide a multi-tasking machine equipped with a separation shutter for dividing the space between a plurality of work sections.
　本発明の一態様における複合加工機は、前側に低くなるよう傾斜した前側傾斜面を備えたベッドと、前記ベッドの機体幅方向に配置された複数の作業部と、前記複数の作業部の間に配置され、前記ベッド上を前後に移動する分離シャッタと、前記分離シャッタに回動可能に取り付けられ、前記分離シャッタの前進にともない前記分離シャッタの下方に展開する拡張シャッタと、を有する。 A multi-tasking machine according to an aspect of the present invention includes a bed including a front inclined surface that is inclined toward the front, a plurality of working sections arranged in the width direction of the machine body of the bed, and a space between the plurality of working sections. a separation shutter that is disposed on the bed and moves back and forth on the bed; and an expansion shutter that is rotatably attached to the separation shutter and expands below the separation shutter as the separation shutter moves forward.
　前記構成によれば、分離シャッタに収納した拡張シャッタが展開することにより、分離シャッタの単純な直線的移動を可能にしつつ、分離位置で機内を遮断する面積を大きくすることができるため、前側傾斜面を備えたベッドであっても、拡張シャッタが分離シャッタだけでは遮断できないその傾斜部分の遮断も行うことが可能になる。 According to the above configuration, by deploying the expansion shutter housed in the separation shutter, it is possible to make simple linear movement of the separation shutter and increase the area that blocks off the inside of the aircraft at the separation position, so that the front side tilt Even if the bed has a surface, the expansion shutter can also block the sloped portion of the bed that cannot be blocked by the separation shutter alone.

The multitasking machine of this embodiment is a machine tool that has the functions of both an NC lathe and a machining center. 1 and 2 are a perspective view and a side view showing the main structure of the multitasking machine of this embodiment.

　複合加工機１は、更に工具主軸装置２に対する工具の交換を行う自動工具交換装置および、第１ワーク主軸装置３および第２ワーク主軸装置４へとワークＷを搬送するワーク自動搬送装置が設けられている。そうした複合加工機１は、機体カバーによって全体が覆われ、機内の空間は、図７に示すように、２枚の分離シャッタ１５などによって仕切られるようになっている。図７は、分離シャッタ１５などに仕切られた複合加工機１の機内を簡略化して示した正面図である。 The multitasking machine 1 is further provided with an automatic tool changer for exchanging tools with respect to the tool spindle device 2, and an automatic work transfer device for conveying the work W to the first work spindle device 3 and the second work spindle device 4. ing. Such a multi-tasking machine 1 is entirely covered with a body cover, and the space inside the machine is partitioned off by two separation shutters 15, etc., as shown in FIG. FIG. 7 is a simplified front view showing the interior of the multitasking machine 1 partitioned by separation shutters 15 and the like.
　複合加工機１の機内は、各装置同士が関係するＺ軸方向の動作を可能にする広い空間を構成するとともに、異なる３つの作業部に対応した空間に分けられるようにもなっている。複合加工機１における３つの作業部に対応した空間とは、第１ワーク主軸装置３で把持したワークＷを加工する第１加工室１０Ａ、第２ワーク主軸装置４で把持されたワークＷを加工する第２加工室１０Ｂ、そして工具主軸装置２における工具交換を行う工具主軸空間１０Ｃである。 The interior of the multitasking machine 1 constitutes a wide space that allows each device to operate in the Z-axis direction, and is also divided into spaces corresponding to three different work sections. The spaces corresponding to the three working sections in the multitasking machine 1 are a first machining chamber 10A for machining the workpiece W gripped by the first workpiece spindle device 3, and a space for machining the workpiece W gripped by the second workpiece spindle device 4. and a tool spindle space 10C in which tools are exchanged in the tool spindle device 2.
　２枚の分離シャッタ１５は、図１において一点鎖線で示すように工具主軸装置２の両側にあって、第１タレット装置５および第２タレット装置６の間の２箇所に設けられている。ここで、図３は、分離シャッタ１５などを示した斜視図であり、図４は、分離シャッタ１５などを示した側面図である。そして、図５は、分離シャッタ１５などを示した図３のＭ－Ｍ矢視断面図である。なお、左右対称に配置された２枚の分離シャッタ１５は同じ構成をしているため、一方のみを示して説明する。 The two separation shutters 15 are provided at two locations on both sides of the tool spindle device 2, between the first turret device 5 and the second turret device 6, as shown by the dashed line in FIG. Here, FIG. 3 is a perspective view showing the separation shutter 15 and the like, and FIG. 4 is a side view showing the separation shutter 15 and the like. 5 is a sectional view taken along the line MM in FIG. 3, showing the separation shutter 15 and the like. Note that since the two separation shutters 15 arranged symmetrically have the same configuration, only one will be shown and explained.
　複合加工機１にはベッド７にシャッタフレーム５１が固定され、分離シャッタ１５は、機体前後方向に移動できるように、そのシャッタフレーム５１に組付けられている。コの字形のシャッタフレーム５１は、その上部に機体前後方向に延びる水平なＹ軸方向のガイドフレーム５２が固定され、分離シャッタ１５の上辺部分には２個のガイドローラ５３が取り付けられ、ガイドフレーム５２の中に転動可能に入れられている。 A shutter frame 51 is fixed to the bed 7 of the multitasking machine 1, and the separation shutter 15 is assembled to the shutter frame 51 so as to be movable in the longitudinal direction of the machine. The U-shaped shutter frame 51 has a horizontal guide frame 52 in the Y-axis direction extending in the longitudinal direction of the aircraft fixed to its upper part, and two guide rollers 53 are attached to the upper side of the separation shutter 15. 52 so that it can roll.
　一方、ベッド７の水平な平面部にはシャッタフレーム５１の枠内に位置するように支持用ブラケット５４が固定され、鉛直に起立した支持プレート６１には２個のガイド部材５５がＹ軸方向の２箇所に固定されている。一方、分離シャッタ１５側にはガイドレール５６が固定され、そのガイドレール５６が２箇所のガイド部材５５に対して摺接可能に嵌め込まれている。従って、分離シャッタ１５は、下側で摺接するガイドレール５６と上側で転動するガイドローラ５３とによって支持され、起立した姿勢が維持された状態でＹ軸方向の水平な移動が可能になっている。 On the other hand, a support bracket 54 is fixed to the horizontal plane part of the bed 7 so as to be positioned within the frame of the shutter frame 51, and two guide members 55 are fixed to the vertical support plate 61 in the Y-axis direction. It is fixed in two places. On the other hand, a guide rail 56 is fixed to the separation shutter 15 side, and the guide rail 56 is fitted into two guide members 55 in a slidable manner. Therefore, the separation shutter 15 is supported by the guide rail 56 that slides on the lower side and the guide roller 53 that rolls on the upper side, and can move horizontally in the Y-axis direction while maintaining an upright posture. There is.
　分離シャッタ１５は、図５に示すように中空の箱型形状であって、その内面にはガイドレール５６が固定されている。ガイドレール５６が位置する分離シャッタ１５の下部には、幅方向に広がった収納部１５１が長手方向（Ｙ軸方向）全体に形成され、底面に切られたスリットを通して支持プレート６１が下から進入している。また、その収納部１５１内には、分離シャッタ１５を移動させるため、Ｙ軸方向に伸縮作動するよう取り付けられたエアシリンダ５８が収められている。 The separation shutter 15 has a hollow box shape as shown in FIG. 5, and has a guide rail 56 fixed to its inner surface. At the bottom of the separation shutter 15 where the guide rail 56 is located, a storage section 151 that extends in the width direction is formed throughout the length direction (Y-axis direction), and the support plate 61 enters from below through a slit cut in the bottom surface. ing. Further, in the housing portion 151, an air cylinder 58 is housed, which is attached to extend and contract in the Y-axis direction in order to move the separation shutter 15.
　支持プレート６１には機体後方側に延びた支持用金具６３が水平に固定されている。エアシリンダ５８は、ヘッド側端部が支持用金具６３の後方側端部に固定され、ロッド側端部は支持プレート６１に接合された支持用ブラケット６４に固定されている。そして、エアシリンダ５８は、水平に伸縮作動するピストンロッド５８１の先端部が分離シャッタ１５内部に固定された連結金具５９に結合している。 A supporting metal fitting 63 extending toward the rear of the fuselage is horizontally fixed to the support plate 61. The head side end of the air cylinder 58 is fixed to the rear side end of the support fitting 63, and the rod side end is fixed to the support bracket 64 joined to the support plate 61. The air cylinder 58 has a piston rod 581 that extends and contracts horizontally, and its distal end portion is connected to a connecting fitting 59 that is fixed inside the separation shutter 15 .
　分離シャッタ１５は、エアシリンダ５８の伸縮作動によって機体前後方向に移動し、図３において実線で示す退避位置と、一点鎖線（図４の実線）で示す分離位置とに切り換えられるようになっている。図３において一点鎖線で示す分離位置の分離シャッタ１５には、下方から飛び出すようにして拡張シャッタ１６が展開している。すなわち、分離シャッタ１５と拡張シャッタ１６とによって、機内を遮断する面積が大きくなるよう構成されている。これは、複合加工機１のベッド７がスラント型であり、四角形状の分離シャッタ１５だけでは、分離位置において重なる前側傾斜面１１との間に隙間ができてしまうことに対応している。 The separation shutter 15 is moved in the longitudinal direction of the aircraft by the expansion and contraction operation of the air cylinder 58, and can be switched between a retracted position shown by a solid line in FIG. 3 and a separation position shown by a dashed-dotted line (solid line in FIG. 4). . At the separation shutter 15 in the separation position shown by the dashed line in FIG. 3, an expansion shutter 16 is deployed so as to pop out from below. In other words, the separation shutter 15 and the expansion shutter 16 are configured to increase the area for blocking the inside of the machine. This corresponds to the fact that the bed 7 of the multitasking machine 1 is of a slant type, and if only the rectangular separation shutter 15 is used, a gap will be created between the bed 7 and the overlapping front inclined surface 11 at the separation position.
　第１加工室１０Ａ、第２加工室１０Ｂおよび工具主軸空間１０Ｃの間に隙間が生じてしまい、隣り合う空間での遮断が不十分な場合には、作業者が機内の作業を行うためには複合加工機１全体を停止させる必要があった。そこで、本実施形態ではその隙間を拡張シャッタ１６が塞ぐようにした構成がとられている。拡張シャッタ１６は、前側傾斜面１１のガイドレール２５を覆うテレスコカバー４１の形状に合わせ、且つ分離シャッタ１５内で回動できるような形状で形成されている。 If a gap occurs between the first machining chamber 10A, the second machining chamber 10B, and the tool spindle space 10C, and the isolation between adjacent spaces is insufficient, it will be difficult for the operator to work inside the machine. It was necessary to stop the entire multitasking machine 1. Therefore, in this embodiment, a configuration is adopted in which the expansion shutter 16 closes the gap. The expansion shutter 16 is formed in a shape that matches the shape of the telescopic cover 41 that covers the guide rail 25 of the front inclined surface 11 and is rotatable within the separation shutter 15.
　拡張シャッタ１６は、その端部が分離シャッタ１５側に固定された横向きの回動軸に軸支され、回動しながら一体になって移動するよう構成されている。支持用ブラケット５４の支持プレート６２にはＹ軸に平行なガイドレール６６が接合され、そこには拡張シャッタ１６の回動軸に設けられたローラ６５が転動可能に入り込んでいる。コの字形をしたガイドレール６６は、前記回動軸側に開くよう横向きに固定され、ローラ６５は、その開口側からガイドレール６６内に入れられ、その下面を転動するよう構成されている。また、ガイドレール６６の下面にはガイドプレート６７が設けられ、拡張シャッタ１６の一部が摺接可能に当たっている。拡張シャッタ１６は、分離シャッタ１５と一体となって移動する際、ガイドプレート６７に当たる箇所の変化に応じて状態が切り換えられるよう構成されている（図４参照）。 The expansion shutter 16 is configured such that its end portion is pivotally supported by a horizontal rotation shaft fixed to the separation shutter 15 side, and moves integrally while rotating. A guide rail 66 parallel to the Y axis is joined to the support plate 62 of the support bracket 54, and a roller 65 provided on the rotation axis of the expansion shutter 16 is rotatably inserted therein. The U-shaped guide rail 66 is fixed horizontally so as to open toward the rotation axis, and the roller 65 is inserted into the guide rail 66 from the opening side and is configured to roll on the lower surface thereof. . Further, a guide plate 67 is provided on the lower surface of the guide rail 66, and a portion of the expansion shutter 16 is slidably abutted thereon. When the expansion shutter 16 moves together with the separation shutter 15, it is configured so that its state can be switched according to a change in the location where it hits the guide plate 67 (see FIG. 4).
　ここで、図６は、拡張シャッタ１６の状態変化を示した図である。拡張シャッタ１６を案内するガイドプレート６７は、その先端部分に約９０度曲げられた湾曲部６７１が形成されている。拡張シャッタ１６は、所定厚の板材であってガイドプレート６７を摺接する箇所がその湾曲部６７１を通過することによって回動し、収納状態Ａから中間状態Ｂ（図４ではＢ１，Ｂ２）、そして遮断状態Ｃへと展開し、またはその逆方向に状態が変化するようになっている。 Here, FIG. 6 is a diagram showing changes in the state of the extended shutter 16. A guide plate 67 that guides the expansion shutter 16 has a curved portion 671 bent at approximately 90 degrees at its tip. The expansion shutter 16 is made of a plate material of a predetermined thickness, and rotates when the part that slides on the guide plate 67 passes through its curved part 671, and changes from the storage state A to the intermediate state B (B1 and B2 in FIG. 4), and The state is designed to develop to the cutoff state C or change in the opposite direction.
　拡張シャッタ１６は、ローラ６５が軸支された幅細の矩形部分から大きく広がるようにして遮断部分が形成されている。拡張シャッタ１６の外径形状は、その矩形部分の直線部７１から遮断部分にかけて約９０度に曲がった曲線部７２が形成され、更に直線の作用部７３を介してガイドレール６６に摺接する角部７４にまで連続している。更に、角部７４の隣にはテレスコカバー４１の形状に対応させた合わせ部７５が形成され、回動時に中心位置からの距離を大きくしない形状の外周部７６や、その外周部７６から矩形部分へと戻る直線部７７が連続している。 The expansion shutter 16 has a blocking portion that greatly expands from a narrow rectangular portion on which the roller 65 is pivotally supported. The outer diameter shape of the expansion shutter 16 is such that a curved part 72 bent at approximately 90 degrees is formed from a straight part 71 of the rectangular part to the blocking part, and a corner part that slides into contact with the guide rail 66 via a straight acting part 73. It continues up to 74. Furthermore, a matching part 75 corresponding to the shape of the telescopic cover 41 is formed next to the corner part 74, and an outer peripheral part 76 having a shape that does not increase the distance from the center position during rotation, and a rectangular part from the outer peripheral part 76 are formed. The straight line section 77 that returns to is continuous.
　続いて、分離シャッタ１５および拡張シャッタ１６の作用について説明する。図３に実線で示す退避位置の分離シャッタ１５は、その中に収納状態Ａの拡張シャッタ１６が収められている。分離シャッタ１５が退避位置にある場合は、複合加工機１の機内は工具主軸装置２によって第１ワーク主軸装置３や第２ワーク主軸装置４に把持されたワークＷに対する加工および、第１ワーク主軸装置３と第２ワーク主軸装置４との間のワークＷの受け渡しなどが可能になる。 Next, the functions of the separation shutter 15 and the expansion shutter 16 will be explained. The separation shutter 15 in the retracted position shown by the solid line in FIG. 3 has the extended shutter 16 in the retracted state A accommodated therein. When the separation shutter 15 is in the retracted position, the inside of the multitasking machine 1 is used to process the workpiece W held by the first workpiece spindle device 3 or the second workpiece spindle device 4 using the tool spindle device 2, and to process the workpiece W gripped by the first workpiece spindle device 3 and the second workpiece spindle device 4. It becomes possible to transfer the workpiece W between the device 3 and the second workpiece spindle device 4.
　一方、エアシリンダ５８が伸長作動した場合には、分離シャッタ１５は、そのガイドレール５６がガイド部材５５を摺接し、上部のガイドローラ５３がガイドフレーム５２内を転動する。分離シャッタ１５は、Ｙ軸に沿って機体前方側へとスライドし、退避位置から分離位置へ移動して機内の分離が行われる。すなわち、複合加工機１の機内には、隣同士の作業部を遮断した第１加工室１０Ａ、第２加工室１０Ｂおよび工具主軸空間１０Ｃが構成される。 On the other hand, when the air cylinder 58 is extended, the guide rail 56 of the separation shutter 15 slides on the guide member 55, and the upper guide roller 53 rolls within the guide frame 52. The separation shutter 15 slides toward the front of the machine along the Y axis, moves from the retreat position to the separation position, and separates the interior of the machine. That is, inside the multitasking machine 1, a first machining chamber 10A, a second machining chamber 10B, and a tool spindle space 10C are configured, in which adjacent working sections are isolated from each other.
　分離シャッタ１５が機体前方へと移動する際、拡張シャッタ１６は、角部７４がガイドプレート６７を摺接し、湾曲部６７１を通過したところで回動が開始して、図６の収納状態Ａから中間状態Ｂ（図４のＢ１，Ｂ２）へと変化する。拡張シャッタ１６は、作用部７３および曲線部７２が湾曲部６７１を摺接することにより傾きが徐々に変化し、その後、直線部７１がガイドプレート６７の直線に沿うようにして遮断状態Ｃになる。よって、図４に示すように、分離シャッタ１５と拡張シャッタ１６とが機内を仕切ることになるため、隣り合う第１加工室１０Ａと工具主軸空間１０Ｃ、そして第２加工室１０Ｂと工具主軸空間１０Ｃとの間がそれぞれ、ほぼ遮断された分離状態になる。 When the separation shutter 15 moves toward the front of the aircraft, the expansion shutter 16 begins to rotate when the corner portion 74 slides on the guide plate 67 and passes through the curved portion 671, changing from the stored state A in FIG. The state changes to state B (B1 and B2 in FIG. 4). The expansion shutter 16 gradually changes its inclination as the action portion 73 and the curved portion 72 slide against the curved portion 671, and then enters the blocking state C with the straight portion 71 following the straight line of the guide plate 67. Therefore, as shown in FIG. 4, the separation shutter 15 and the expansion shutter 16 partition the inside of the machine, so that the adjacent first machining chamber 10A and tool spindle space 10C, and the second machining chamber 10B and tool spindle space 10C are separated. and are in a state of separation where they are almost cut off.
　次に、分離シャッタ１５が分離位置から退避位置へと戻される場合には、エアシリンダ５８が収縮作動し、分離シャッタ１５がピストンロッド５８１に引っ張られて機体後方へとスライドする。その際、拡張シャッタ１６も機体後方へと引っ張れ、曲線部７２が湾曲部６７１に当たって摺接し、そこからローラ６５の回動軸を中心とした回動が開始する。すなわち、拡張シャッタ１６は、曲線部７２に続いて作用部７３が湾曲部６７１を摺接することによって傾きが戻され、遮断状態Ｃから中間状態Ｂへと変化する。そして、拡張シャッタ１６は、角部７４がガイドプレート６７の平面部を摺接するようにした回動により、収納状態Ａに戻されて分離シャッタ１５内に収められる。 Next, when the separation shutter 15 is returned from the separation position to the retracted position, the air cylinder 58 is contracted, and the separation shutter 15 is pulled by the piston rod 581 and slides toward the rear of the machine. At this time, the expansion shutter 16 is also pulled toward the rear of the machine, and the curved portion 72 comes into sliding contact with the curved portion 671, and from there the rotation of the roller 65 about the rotation axis begins. That is, the expansion shutter 16 is tilted back by the action portion 73 slidingly contacting the curved portion 671 following the curved portion 72, and changes from the blocking state C to the intermediate state B. Then, the expansion shutter 16 is returned to the storage state A and stored in the separation shutter 15 by rotating so that the corner portion 74 comes into sliding contact with the flat surface of the guide plate 67.
　従って、本実施形態の複合加工機１によれば、分離シャッタ１５に収納した拡張シャッタ１６が展開することにより、水平な分離シャッタ１５の単純な移動を可能にしつつ、分離位置で機内を遮断する面積を大きくすることができる。特に、前側傾斜面１１が形成されたスラント型のベッド７であっても、拡張シャッタ１６によって隣同士を分離することができる。そのため、例えば第２ワーク主軸装置４側で加工が行われている状況でも、第１加工室１０Ａの第１ワーク主軸装置３と第１タレット装置５を停止させ、タレット２７に対する工具交換作業を行うことができる。 Therefore, according to the multi-tasking machine 1 of this embodiment, by deploying the expansion shutter 16 housed in the separation shutter 15, it is possible to simply move the separation shutter 15 horizontally, while blocking the inside of the machine at the separation position. The area can be increased. In particular, even if the bed 7 is of a slant type in which the front inclined surface 11 is formed, adjacent beds can be separated from each other by the expansion shutter 16. Therefore, for example, even if machining is being performed on the second workpiece spindle device 4 side, the first workpiece spindle device 3 and the first turret device 5 in the first processing chamber 10A are stopped, and the tool exchange operation for the turret 27 is performed. be able to.
　また、拡張シャッタ１６は、ガイドプレート６７の湾曲部６７１を摺接するその形状（曲線部７２、作用部７３）に従って回動するものであるため、狭い分離シャッタ１５内でも簡単な構成によって、分離シャッタ１５と一体になって移動する移動位置に従った状態変化を可能にしている。そして、本実施形態の複合加工機１は、分離シャッタ１５と展開した拡張シャッタ１６とによって、第１加工室１０Ａ、第２加工室１０Ｂおよび工具主軸空間１０Ｃに分離するとともに、機内を一つの空間にして離れた装置間の作業も可能になっている。 In addition, since the expansion shutter 16 rotates according to its shape (curved portion 72, action portion 73) that slides against the curved portion 671 of the guide plate 67, the expansion shutter 16 can be easily configured even within the narrow separation shutter 15. 15, it is possible to change the state according to the movement position. The multi-tasking machine 1 of this embodiment is separated into a first machining chamber 10A, a second machining chamber 10B, and a tool spindle space 10C by the separation shutter 15 and the expanded expansion shutter 16, and the inside of the machine is integrated into one space. This makes it possible to work between separate devices.
　本発明の一実施形態について説明したが、本発明はこれらに限定されるものではなく、その趣旨を逸脱しない範囲で様々な変更が可能である。
　例えば、複合加工機は前述した実施形態の構成には限らず、工具主軸装置２を除く対向２軸旋盤であって、分離シャッタ１５と拡張シャッタ１６は一組だけであってもよい。 Although one embodiment of the present invention has been described, the present invention is not limited thereto, and various changes can be made without departing from the spirit thereof.
For example, the multitasking machine is not limited to the configuration of the embodiment described above, and may be an opposed two-axis lathe excluding the tool spindle device 2, and may include only one set of the separation shutter 15 and the expansion shutter 16.
