Description

本発明は、ラインガイド機構及び旋回装置に関するものである。   The present invention relates to a line guide mechanism and a turning device.

例えば、特許文献1には、旋回装置(旋回主軸装置)を備える工作機械が記載されている。この旋回装置は、旋回軸を45度に傾斜させた状態で回転可能に支持する固定本体部と、旋回軸と共に回転可能な旋回本体部と、旋回軸回りで旋回本体部に支持される主軸装置とを備える。旋回装置は、主軸装置を旋回軸回りで旋回させて垂直姿勢と水平姿勢の間で旋回割出しを行う。   For example, Patent Literature 1 describes a machine tool provided with a turning device (turning spindle device). The turning device includes a fixed main body that rotatably supports the swivel shaft at a 45-degree angle, a swivel main body that can rotate with the swivel shaft, and a spindle device that is supported by the swivel main body around the swivel axis. And The turning device turns the main spindle device around the turning axis to perform turning indexing between a vertical posture and a horizontal posture.

旋回装置を備える工作機械では、旋回装置から主軸装置に電気や油気圧等の供給が必要であるため、電気を通す電気配線路や油気圧等を通す流体配管路等のラインが設けられる。このようなラインは、旋回装置の旋回運動で所定の許容範囲を超えてねじれた場合は、破断や破損が生じるおそれがある。そこで、ラインは、所定の許容範囲を超えてねじれないように、例えば、特許文献2に記載の旋回運動に対応した巻取り型のガイドに収容されて保護される。   In a machine tool equipped with a turning device, it is necessary to supply electricity, oil pressure, and the like from the turning device to the spindle device. Therefore, a line such as an electric wiring path for passing electricity or a fluid piping path for passing oil pressure or the like is provided. If such a line is twisted beyond a predetermined allowable range by the turning motion of the turning device, there is a possibility that the line may be broken or damaged. Therefore, the line is protected by, for example, being accommodated in a winding-type guide corresponding to a turning motion described in Patent Literature 2 so as not to be twisted beyond a predetermined allowable range.

特許文献2に記載のガイドにおいて、旋回軸の旋回可能角度を大きくするためには、ガイドの直動範囲を大きくとる(収容面積を大きくする)必要があり、旋回装置が大型化する。また、ガイドの運動を安定させるためには、複雑形状なガイド板が必要となり、部品点数の増大や組付け工数の増加によりコスト高となる傾向にある。   In the guide described in Patent Literature 2, in order to increase the swivelable angle of the swivel axis, it is necessary to increase the linear motion range of the guide (enlarge the accommodation area), and the swivel device becomes large. Further, in order to stabilize the movement of the guide, a guide plate having a complicated shape is required, and the cost tends to increase due to an increase in the number of parts and an increase in the number of assembly steps.

本発明は、このような事情に鑑みてなされたものであり、シンプルで小型な構成のラインガイド機構及び当該ラインガイド機構を備える旋回装置を提供することを目的とする。   The present invention has been made in view of such circumstances, and an object of the present invention is to provide a line guide mechanism having a simple and small configuration and a turning device including the line guide mechanism.

本発明に係るラインガイド機構は、回転規制されて配置される第一案内筒と、前記第一案内筒の中心軸線と同軸で直列配置され、前記中心軸線の回りに回転可能に配置される第二案内筒と、第一円筒部材及び前記第一円筒部材に対し放射状に突設される少なくとも2つの第一突状部材を有し、前記直列配置される第一案内筒及び第二案内筒のうち、前記第一案内筒の開放端側に一体もしくは別体で設けられる第一仕切り部材と、第二円筒部材及び前記第二円筒部材に対し放射状に突設される少なくとも2つの第二突状部材を有し、前記直列配置される第一案内筒及び第二案内筒のうち、前記第二案内筒の開放端側に一体もしくは別体で設けられる第二仕切り部材と、第三円筒部材及び前記第三円筒部材に対し放射状に突設される少なくとも2つの第三突状部材を有し、前記第一仕切り部材と前記第二仕切り部材との間に配置される第三仕切り部材と、前記第一円筒部材、前記第三円筒部材及び前記第二円筒部材の中心を貫通して回転可能に配置され、前記第一仕切り部材もしくは前記第二仕切り部材に連結される支柱部材と、を備える。   The line guide mechanism according to the present invention includes a first guide cylinder, which is arranged to be restricted in rotation, and is arranged in series coaxially with a center axis of the first guide cylinder, and is arranged so as to be rotatable around the center axis. Two guide cylinders, having a first cylindrical member and at least two first projecting members radially protruding from the first cylindrical member, the first guide tube and the second guide tube arranged in series A first partition member integrally or separately provided on an open end side of the first guide cylinder, and at least two second protrusions radially protruding from the second cylindrical member and the second cylindrical member; Having a member, of the first guide tube and the second guide tube arranged in series, a second partition member provided integrally or separately on the open end side of the second guide tube, and a third cylindrical member; At least two protruding radially with respect to the third cylindrical member; A third partition member disposed between the first partition member and the second partition member, the first cylindrical member, the third cylindrical member, and the second cylinder A support member rotatably disposed through a center of the member and connected to the first partition member or the second partition member.

そして、ラインを、前記第一案内筒の内周と前記第一仕切り部材の前記第一突状部材で仕切られる区画に通し、さらに前記第一案内筒の内周もしくは前記第二案内筒の内周と前記第三仕切り部材の前記第三突状部材で仕切られる区画に通し、さらに前記第二案内筒の内周と前記第二仕切り部材の前記第二突状部材で仕切られる区画に通した状態で、前記第二案内筒の回転に応じて案内する。   Then, the line is passed through the inner periphery of the first guide cylinder and a section partitioned by the first protruding member of the first partition member, and further, the inner periphery of the first guide cylinder or the inner periphery of the second guide cylinder. Through the section of the third partition member that is partitioned by the third protruding member, and further pass through the inner circumference of the second guide cylinder and the section that is partitioned by the second protruding member of the second partition member. In this state, the guide is performed according to the rotation of the second guide cylinder.

このラインガイド機構においては、第二案内筒の回転角度を大きくしても円筒状の第一案内筒内及び第二案内筒内においてラインを案内できる。すなわち、ラインガイド機構においては、第二案内筒が回転軸線回りに回転すると、第二案内筒の第二突状部材がラインを押し、さらに当該ラインが第三仕切り部材の第三突状部材を押して回転軸線回りに螺旋状に旋回してラインを案内する。このように、シンプルで小型なラインガイド機構に構成できる。   In this line guide mechanism, even if the rotation angle of the second guide cylinder is increased, the line can be guided in the first and second cylindrical guide cylinders. That is, in the line guide mechanism, when the second guide cylinder rotates around the rotation axis, the second protruding member of the second guide cylinder pushes the line, and the line further moves the third protruding member of the third partition member. Push to spiral around the axis of rotation and guide the line. In this way, a simple and small line guide mechanism can be configured.

本発明に係る旋回装置は、工作物の加工用の回転工具を有する主軸装置を備える旋回本体部と、前記旋回本体部を旋回軸線回りで回転可能に支持する固定本体部と、前記旋回本体部の旋回軸線上に配置される上記ラインガイド機構と、を備える旋回装置であって、前記第一案内筒は、前記固定本体部に連結され、前記第二案内筒は、前記旋回本体部に連結される。   A turning device according to the present invention includes a turning main unit including a spindle device having a rotating tool for processing a workpiece, a fixed main unit that supports the turning main unit so as to be rotatable around a turning axis, and the turning main unit. Wherein the first guide cylinder is connected to the fixed main body, and the second guide cylinder is connected to the pivot main body. Is done.

これによれば、上述の理由によりシンプルで小型なラインガイド機構に構成できるので、旋回本体部の回転角度を大きくしても、旋回装置の大型化を抑制できる。   According to this, a simple and small line guide mechanism can be configured for the above-described reason, so that even if the rotation angle of the turning main body is increased, it is possible to suppress an increase in the size of the turning device.

Three rectangular plate-shaped third projecting members 55b are radially arranged at equal angular intervals (120 degrees) on the outer periphery of the three cylindrical members 55a. In the case of a resin, for example, polyamide, polytetrafluoroethylene, or the like having a low coefficient of friction is used. In the case of metal, the surface is subjected to a process for lowering the friction coefficient, for example, a shot peening process, a shot blast process, or a DLC process.

図3に示すように、第一羽部材551及び第二羽部材552は、連結された第一、第二、第三支柱部材541,542,543のうち第一支柱部材541及び第二支柱部材542における小径部54aに対し、旋回軸線D回りに回転可能にそれぞれ配置される。そして、第一羽部材551及び第二羽部材552の各第三円筒部材55aの内周には、第一支柱部材541及び第二支柱部材542における各小径部54aに対してスムーズな回転が可能なように、図9A及び図9Bに示す軸受55cが挿入される。   As shown in FIG. 3, the first wing member 551 and the second wing member 552 are formed of the first, second, and third support members 541, 542, and 543. Each of the small-diameter portions 54a at 542 is disposed so as to be rotatable around the rotation axis D. The inner circumference of each third cylindrical member 55a of the first wing member 551 and the second wing member 552 can smoothly rotate with respect to each small diameter portion 54a of the first support member 541 and the second support member 542. Thus, the bearing 55c shown in FIGS. 9A and 9B is inserted.

軸受55cは、低摩擦係数の樹脂、例えばポリアセタール、ポリアミド、ポリテトラフルオロエチレン等で形成される。なお、第二仕切り部材532の第二円筒部材532aの内周にも、第三支柱部材543の小径部54aに対してスムーズな回転が可能なように、軸受55cが挿入される。ただし、第一、第二羽部材551,552の各第三円筒部材55aと第一、第二支柱部材541,542との摺動性、第二仕切り部材532の第二円筒部材532aと第三支柱部材543との摺動性が担保されていれば、軸受55cは不要である。   The bearing 55c is formed of a resin having a low coefficient of friction, for example, polyacetal, polyamide, polytetrafluoroethylene, or the like. The bearing 55c is also inserted into the inner periphery of the second cylindrical member 532a of the second partition member 532 so that the small-diameter portion 54a of the third support member 543 can rotate smoothly. However, the slidability between each third cylindrical member 55a of the first and second wing members 551 and 552 and the first and second support members 541 and 542, and the second cylindrical member 532a and the third If the slidability with the support member 543 is ensured, the bearing 55c is unnecessary.

角度制限機構56は、図8A及び図8Bに示すように、第一羽部材551及び第二羽部材552にそれぞれ設けられる当接ピン56aと、図6A,6B及び図7A,7Bに示すように、第一支柱部材541及び第二支柱部材542にそれぞれ設けられる2つの第一、第二固定ピン56b,56cを備える。角度制限機構56は、連結された第一支柱部材541に対する第一羽部材551の回転可能角度、及び連結された第二支柱部材542に対する第二羽部材552の回転可能角度をそれぞれ制限する。   As shown in FIGS. 8A and 8B, the angle limiting mechanism 56 includes contact pins 56a provided on the first wing member 551 and the second wing member 552, respectively, and as shown in FIGS. 6A, 6B and 7A, 7B. , And two first and second fixing pins 56b and 56c provided on the first support member 541 and the second support member 542, respectively. The angle limiting mechanism 56 limits the rotatable angle of the first wing member 551 with respect to the connected first support member 541 and the rotatable angle of the second wing member 552 with respect to the connected second support member 542.

具体的には、図8A及び図8Bに示すように、当接ピン56aは、第一羽部材551及び第二羽部材552の第三円筒部材55aの端面における一の第三突状部材55bの根本の位置において、中心軸線C4方向に突出するようにそれぞれ設けられる。また、図6A及び図6Bに示すように、第一支柱部材541の第一固定ピン56bは、小径部54aにおける第一羽部材551と大径部54bとの間の外周において、第一羽部材551の当接ピン56aと当接可能なように径方向に突出して設けられる。   Specifically, as shown in FIG. 8A and FIG. 8B, the contact pin 56a is provided on one end of the third protruding member 55b on the end surface of the third cylindrical member 55a of the first wing member 551 and the second wing member 552. At the root position, they are provided so as to protrude in the direction of the central axis C4. As shown in FIGS. 6A and 6B, the first fixing pin 56b of the first support member 541 is provided on the outer periphery between the first wing member 551 and the large-diameter portion 54b in the small-diameter portion 54a. 551 protruding in the radial direction so as to be able to contact the contact pin 56a.

そして、第一支柱部材541の第二固定ピン56cは、第一固定ピン56bから反時計回りに60度の位置において、第一羽部材551の当接ピン56aと当接可能なように径方向に突出して設けられる。つまり、第一羽部材551は、第一支柱部材541に対して第一固定ピン56bと第二固定ピン56cの間の60度で回転角度が制限される。   The second fixing pin 56c of the first support member 541 is radially moved so as to be able to contact the contact pin 56a of the first blade member 551 at a position 60 degrees counterclockwise from the first fixing pin 56b. Is provided to protrude. That is, the rotation angle of the first wing member 551 with respect to the first support member 541 is limited to 60 degrees between the first fixing pin 56b and the second fixing pin 56c.

また、図7A及び図7Bに示すように、第二支柱部材542の第一固定ピン56bは、小径部54aにおける第二羽部材552と大径部54bとの間の外周において、第二羽部材552の当接ピン56aと当接可能なように径方向に突出して設けられる。そして、第二支柱部材542の第二固定ピン56cは、第一固定ピン56bから反時計回りに120度の位置において、第二羽部材552の当接ピン56aと当接可能なように径方向に突出して設けられる。   As shown in FIGS. 7A and 7B, the first fixing pin 56b of the second support member 542 is provided on the outer periphery between the second wing member 552 and the large-diameter portion 54b in the small-diameter portion 54a. 552 are provided so as to protrude in the radial direction so as to be able to contact the contact pin 56a. The second fixing pin 56c of the second support member 542 is positioned at a position 120 degrees counterclockwise from the first fixing pin 56b so as to be able to contact the contact pin 56a of the second wing member 552 in the radial direction. Is provided to protrude.

つまり、第二羽部材552は、第二支柱部材542に対して第一固定ピン56bと第二固定ピン56cの間の120度で回転角度が制限される。なお、第二仕切り部材532の回転角度は制限する必要がないため、第三支柱部材543には2つの第一、第二固定ピン56b,56cを設けていない。   That is, the rotation angle of the second wing member 552 relative to the second support member 542 is limited to 120 degrees between the first fixing pin 56b and the second fixing pin 56c. Since the rotation angle of the second partition member 532 does not need to be limited, the third support member 543 is not provided with two first and second fixing pins 56b and 56c.

角度制限機構56の第一、第二固定ピン56b,56cの配置角度は、旋回本体部22の回転角度を回転部材の個数、すなわち第一羽部材551、第二羽部材552及び第二仕切り部材532の個数で割った角度に設定される。これにより、ラインガイド機構50は、旋回本体部22の回転に追従して回転することになる。   The arrangement angle of the first and second fixing pins 56b and 56c of the angle limiting mechanism 56 is determined by changing the rotation angle of the turning main body 22 by the number of rotation members, that is, the first wing member 551, the second wing member 552, and the second partition member. The angle is set to the angle divided by the number of 532. As a result, the line guide mechanism 50 rotates following the rotation of the turning main body 22.

本例では、旋回本体部22の回転角度が180度であり、回転部材の個数は3個であるので、第一支柱部材541の第一、第二固定ピン56b,56cの配置角度は60度、第二支柱部材542の第一、第二固定ピン56b,56cの配置角度は120度となる。   In this example, since the rotation angle of the turning main body 22 is 180 degrees and the number of rotating members is three, the arrangement angle of the first and second fixing pins 56b and 56c of the first support member 541 is 60 degrees. The arrangement angle of the first and second fixing pins 56b and 56c of the second support member 542 is 120 degrees.

図10に示すように、第一仕切り部材531は、第一突状部材531bで第一案内筒51の内周を周方向に3つの領域A1−A3に区画し、第二仕切り部材532は、第二突状部材532bで第二案内筒52の内周を周方向に3つの領域A1−A3に区画する。また、図11に示すように、第一羽部材551は、第三突状部材55bで第一案内筒51の内周を周方向に3つの領域B1−B3に区画し、第二羽部材552は、第三突状部材55bで第二案内筒52の内周を周方向に3つの領域B1−B3に区画する。   As shown in FIG. 10, the first partition member 531 divides the inner circumference of the first guide cylinder 51 into three regions A1 to A3 in the circumferential direction by the first protrusion members 531b, and the second partition member 532 The inner circumference of the second guide cylinder 52 is divided into three regions A1-A3 in the circumferential direction by the second protruding member 532b. As shown in FIG. 11, the first wing member 551 divides the inner circumference of the first guide cylinder 51 into three regions B <b> 1 to B <b> 3 in the circumferential direction with the third protruding member 55 b, and the second wing member 552. Divides the inner circumference of the second guide cylinder 52 into three regions B1-B3 in the circumferential direction by the third protruding member 55b.

そして、図3、図10及び図11に示すように、ラインガイド機構50においては、第一仕切り部材531の領域A1−A3から、第一羽部材551の領域B1−B3及び第二羽部材552の領域B1−B3を通って第二仕切り部材532の領域A1−A3にわたって、電気配線路26及び流体配管路28が種類別等で分配して挿通される。   Then, as shown in FIGS. 3, 10 and 11, in the line guide mechanism 50, the area B1-B3 of the first wing member 551 and the area B1-B3 of the first wing member 551 are moved from the area A1-A3 of the first partition member 531. The electric wiring passages 26 and the fluid piping passages 28 are distributed and inserted according to types and the like over the regions A1 to A3 of the second partition member 532 through the regions B1 to B3.

例えば、電気配線路26のうち動力線26bは、領域A1,B1,B1,A1に挿入し、油圧や空圧を通す流体配管路28は、領域A2,B2,B2,A2に挿入し、電気配線路26のうち信号線26cは、領域A3,B3,B3,A3に挿入する。このように、電気配線路26は、流体配管路28と離間して配置されるので、流体供給のオンオフによる流体配管路28の振れの影響を受けることはない。   For example, the power line 26b of the electric wiring path 26 is inserted into the areas A1, B1, B1, and A1, and the fluid pipe path 28 through which the hydraulic pressure and the pneumatic pressure passes is inserted into the areas A2, B2, B2, and A2. The signal line 26c of the wiring path 26 is inserted into the regions A3, B3, B3, and A3. As described above, since the electric wiring path 26 is disposed separately from the fluid piping path 28, the electric wiring path 26 is not affected by the swing of the fluid piping path 28 due to the on / off of the fluid supply.

また、信号線26cは、動力線26bと離間して配置されるので、ノイズの影響を抑制できる。なお、後述するように電気配線路26及び流体配管路28が緩やかな螺旋を描くように旋回するため、ラインガイド機構50の各領域A1−A3,B1−B3に対する電気配線路26又は流体配管路28の占有率は、40%程度がよい。   Further, since the signal line 26c is disposed apart from the power line 26b, the influence of noise can be suppressed. In addition, since the electric wiring path 26 and the fluid piping path 28 turn so as to draw a gentle spiral as described later, the electric wiring path 26 or the fluid piping path for each area A1-A3, B1-B3 of the line guide mechanism 50. The occupation ratio of 28 is preferably about 40%.

そして、図3に示すように、第一仕切り部材531から上方に出ている電気配線路26及び流体配管路28の上端部分は、旋回本体部22に固定されているクランプ部材26a,28aにゆとりを持たせずに接続される。これにより、旋回本体部22が回転して電気配線路26及び流体配管路28が旋回したとき、当該旋回力が電気配線路26及び流体配管路28の上端部分に伝わり難くなる。   Then, as shown in FIG. 3, the upper end portions of the electric wiring passage 26 and the fluid piping passage 28 protruding upward from the first partition member 531 have room for the clamp members 26 a and 28 a fixed to the turning main body 22. Are connected without having This makes it difficult for the turning force to be transmitted to the upper end portions of the electric wiring path 26 and the fluid piping path 28 when the rotating main body 22 rotates and the electric wiring path 26 and the fluid piping path 28 rotate.

一方、第二仕切り部材532から下方に出ている電気配線路26及び流体配管路28の下端部分は、弛んだ円弧形状となる長さで配線路接続部27及び配管路接続部29と接続される。電気配線路26及び流体配管路28の下端部分を弛んだ円弧形状とする理由は、当該下端部分は重力により垂れ下がる傾向にあるため、当該下端部分の弛んだ円弧形状を維持できるからである。   On the other hand, the lower end portions of the electric wiring passage 26 and the fluid piping passage 28 projecting downward from the second partition member 532 are connected to the wiring passage connecting portion 27 and the piping passage connecting portion 29 with a slack arc-shaped length. You. The reason why the lower end portions of the electric wiring path 26 and the fluid piping path 28 are formed into a slack circular arc shape is that the lower end portion tends to hang down due to gravity, so that the lower end portion can maintain the slack circular arc shape.

この円弧形状の半径は、電気配線路26及び流体配管路28の最小曲げ半径の2倍程度の大きさとする。これにより、旋回本体部22が回転したとき、ラインガイド機構50からの電気配線路26及び流体配管路28の出入り分が吸収されるため、電気配線路26及び流体配管路28が引っ張られることはない。   The radius of this arc shape is about twice the minimum bending radius of the electric wiring path 26 and the fluid piping path 28. Accordingly, when the turning main body portion 22 rotates, the portion of the electric wiring passage 26 and the fluid piping passage 28 coming and going from the line guide mechanism 50 is absorbed, so that the electric wiring passage 26 and the fluid piping passage 28 are not pulled. Absent.

(3.ラインガイド機構の動作)
次に、ラインガイド機構50の動作について図12A、図12B、図13A−図13D及び図14A−図14Dを参照して説明する。なお、各図においては、便宜上、1本の動力線26b及び1本の流体配管路28のみを示す。図12A及び図13A−図13Dに示すように、旋回本体部22が回転角度0度に位置するとき、動力線26b及び流体配管路28は、直線状の状態になっているとする。
(3. Operation of line guide mechanism)
Next, the operation of the line guide mechanism 50 will be described with reference to FIGS. 12A, 12B, 13A to 13D, and 14A to 14D. In each figure, only one power line 26b and one fluid piping 28 are shown for convenience. As shown in FIGS. 12A and 13A to 13D, it is assumed that the power line 26b and the fluid piping 28 are in a linear state when the turning main body 22 is located at the rotation angle of 0 degree.

旋回本体部22が回転角度0度から回転角度180度に向かって回転を開始すると、ラインガイド機構50において、流体配管路28は、第二仕切り部材532の第二突状部材532bに押圧されて、直線状の状態から緩やかな螺旋を描くように旋回する。そして、動力線26bは、第一羽部材551の第三突状部材55b及び第二羽部材552の第三突状部材55bを旋回本体部22の回転方向に押圧する。   When the rotation main body 22 starts rotating from the rotation angle of 0 degrees to the rotation angle of 180 degrees, the fluid piping path 28 is pressed by the second protruding member 532 b of the second partition member 532 in the line guide mechanism 50. Then, it turns so as to draw a gentle spiral from a straight state. Then, the power line 26 b presses the third protruding member 55 b of the first wing member 551 and the third protruding member 55 b of the second wing member 552 in the rotation direction of the turning main body 22.

このとき第一、第二羽部材551,552及び第二仕切り部材532は、上記押圧力が掛かることになるが、第一、第二、第三支柱部材541,542,543が設けられているため、上記押圧力に対する耐久性は担保される。なお、第一案内筒51の内周と第一羽部材551の自由端とのギャップ、第二案内筒52の内周と第二羽部材552の自由端とのギャップ、及び第二案内筒52の内周と第二仕切り部材532の自由端とのギャップは、動力線26b及び流体配管路28が旋回中に当該ギャップを通り抜けないように、動力線26b及び流体配管路28の外径よりも小さくする。信号線26cも同様である。   At this time, the first and second wing members 551 and 552 and the second partition member 532 are subjected to the above-described pressing force, but the first, second, and third support members 541, 542, and 543 are provided. Therefore, the durability against the pressing force is secured. The gap between the inner periphery of the first guide cylinder 51 and the free end of the first wing member 551, the gap between the inner periphery of the second guide cylinder 52 and the free end of the second wing member 552, and the second guide cylinder 52 The gap between the inner circumference of the power line 26b and the free end of the second partition member 532 is smaller than the outer diameter of the power line 26b and the fluid line 28 so that the power line 26b and the fluid line 28 do not pass through the gap during turning. Make it smaller. The same applies to the signal line 26c.

そして、第一羽部材551の第三突状部材55b、第二羽部材552の第三突状部材55b及び第二仕切り部材532の第二突状部材532bが60度回転すると、第一羽部材551の第三突状部材55bは角度制限機構56により回転停止する。次に、第二羽部材552の第三突状部材55b及び第二仕切り部材532の第二突状部材532bが120度回転すると、第二羽部材552の第三突状部材55bは角度制限機構56により回転停止する。最後に、図14A−図14Dに示すように、第二仕切り部材532の第二突状部材532bが180度回転し、旋回本体部22の回転が停止する。   When the third protruding member 55b of the first wing member 551, the third protruding member 55b of the second wing member 552, and the second protruding member 532b of the second partition member 532 rotate by 60 degrees, the first wing member The rotation of the third protruding member 55b 551 is stopped by the angle limiting mechanism 56. Next, when the third protruding member 55b of the second wing member 552 and the second protruding member 532b of the second partition member 532 rotate by 120 degrees, the third protruding member 55b of the second wing member 552 becomes an angle limiting mechanism. The rotation is stopped by 56. Finally, as shown in FIGS. 14A to 14D, the second protruding member 532b of the second partition member 532 rotates 180 degrees, and the rotation of the turning main body 22 stops.

これにより、第一仕切り部材531の領域A1−A3は、固定状態にあるが、第一羽部材551の領域B1−B3、第二羽部材552の領域B1−B3及び第二仕切り部材532の領域A1−A3は、徐々にずれて螺旋状になる。そして、図12Bに示すように、動力線26b及び流体配管路28は、局所的に急激なねじれを生じることはなく、緩やかな螺旋を描くので、破断や破損の発生を低減できる。なお、信号線26cも同様である。   Thus, the areas A1-A3 of the first partition member 531 are in a fixed state, but the areas B1-B3 of the first wing member 551, the areas B1-B3 of the second wing member 552, and the areas of the second partition member 532. A1-A3 is gradually shifted to form a spiral shape. Then, as shown in FIG. 12B, the power line 26b and the fluid piping 28 draw a gentle spiral without causing a sharp twist locally, so that the occurrence of breakage and breakage can be reduced. Note that the same applies to the signal line 26c.

その後、旋回本体部22は、回転角度180度から回転角度0度に向かって先ほどとは逆の回転を開始する。ここで、図16Aに示すように、従来のガイドGでは、旋回軸の旋回角度が例えば0度のときにガイドGの内周を直線状に通るラインLは、図16Bに示すように、旋回軸が0度から180度に旋回したときにガイドGの内周に引き込まれる。そして、旋回軸が180度から0度に旋回すれば、ガイドGの内周に引き込まれたラインLは図16Aに示す元の状態に戻るのである。   Thereafter, the turning main body portion 22 starts the reverse rotation from the rotation angle of 180 degrees toward the rotation angle of 0 degrees. Here, as shown in FIG. 16A, in the conventional guide G, when the turning angle of the turning axis is, for example, 0 degree, a line L passing straight through the inner circumference of the guide G is turned as shown in FIG. 16B. When the shaft turns from 0 degree to 180 degrees, it is drawn into the inner periphery of the guide G. When the turning axis turns from 180 degrees to 0 degrees, the line L drawn into the inner periphery of the guide G returns to the original state shown in FIG. 16A.

ところが、図16Cに示すように、ラインLとガイドGの内周との擦れによる摩擦抵抗等によりガイドGの内周に引き込まれたままで屈曲する場合がある。このラインLの屈曲(図の一点鎖線で囲まれた部分)は、曲率をコントロールすることが難しいため、繰り返し大きな屈曲が発生した場合はラインLの破断に繋がるおそれがある。また、摩擦によりラインLの外皮が摩耗するおそれがある。なお、図16A−図16Cでは、便宜上、ラインは1本のみ示す。   However, as shown in FIG. 16C, there is a case where the wire L is bent while being drawn into the inner circumference of the guide G due to frictional resistance caused by friction between the line L and the inner circumference of the guide G. Since it is difficult to control the curvature of the bending of the line L (the portion surrounded by the dashed line in the drawing), if the bending is repeatedly large, the line L may be broken. Further, the outer skin of the line L may be worn due to friction. 16A to 16C, only one line is shown for convenience.

本実施形態のラインガイド機構50では、第一案内筒51、第二案内筒52、第一羽部材551及び第二羽部材552は摩擦係数の低い樹脂で形成され、又は金属で形成され且つ摩擦係数を下げる処理が施されている。これにより、ラインガイド機構50において、動力線26b及び流体配管路28は、上述とは逆動作、すなわち螺旋を解く方向に旋回して直線状の状態に戻る。よって、動力線26b及び流体配管路28は、第一羽部材551、第二羽部材552及び第二仕切り部材532の内周との擦れによる摩擦抵抗等により、第一羽部材551、第二羽部材552及び第二仕切り部材532の内周に引き込まれたままで屈曲する事態を抑制でき、想定外の破断を防止できる。信号線26cも同様である。   In the line guide mechanism 50 of the present embodiment, the first guide cylinder 51, the second guide cylinder 52, the first wing member 551, and the second wing member 552 are formed of a resin having a low coefficient of friction, or are formed of a metal and have a friction. A process for lowering the coefficient has been performed. As a result, in the line guide mechanism 50, the power line 26b and the fluid piping 28 return to the straight state by reversing the operation described above, that is, turning in the direction in which the spiral is released. Therefore, the power line 26b and the fluid pipe passage 28 cause the first wing member 551, the second wing member 552, the second wing member 552, and the second It is possible to suppress bending while being drawn into the inner circumferences of the member 552 and the second partition member 532, and to prevent unexpected breakage. The same applies to the signal line 26c.

なお、仮に、案内筒を第一案内筒51及び第二案内筒52の2つに分けずに1つにした場合、1つの案内筒において下方における電気配線路26及び流体配管路28の相対回転量は、上方の当該相対回転量よりも大きくなる。よって、電気配線路26及び流体配管路28の擦れによるダメージが大きくなる。そこで、案内筒を第一案内筒51及び第二案内筒52の2つに分けることで、上記相対回転量を小さくして電気配線路26及び流体配管路28の擦れを平均化して、擦れによるダメージを小さくしている。   In addition, if the guide tube is made into one without dividing into the first guide tube 51 and the second guide tube 52, the relative rotation of the electric wiring passage 26 and the fluid piping passage 28 in one guide tube below. The amount will be greater than the relative rotation above. Therefore, damage due to friction between the electric wiring path 26 and the fluid piping path 28 increases. Therefore, by dividing the guide cylinder into two parts, the first guide cylinder 51 and the second guide cylinder 52, the relative rotation amount is reduced, and the friction of the electric wiring passage 26 and the fluid piping passage 28 is averaged, and the friction caused by the friction is reduced. Reduces damage.

(4.旋回装置を備える工作機械の動作)
次に、旋回装置20を備える工作機械1の工作物に対する加工動作について図を参照して説明する。なお、本例では、主軸装置30の姿勢(回転軸線Rの向き)が水平方向(0度)にあるときに工作物の一側面に孔を穿設し、主軸装置30の姿勢(回転軸線Rの向き)が垂直方向(180度)にあるときに工作物の上面に孔を穿設する加工動作について説明する。
(4. Operation of machine tool equipped with turning device)
Next, a machining operation on a workpiece of the machine tool 1 including the turning device 20 will be described with reference to the drawings. In this example, when the posture of the spindle device 30 (the direction of the rotation axis R) is in the horizontal direction (0 degree), a hole is formed in one side surface of the workpiece, and the posture of the spindle device 30 (the rotation axis R The following describes a processing operation for drilling a hole in the upper surface of a workpiece when the direction is in the vertical direction (180 degrees).

工作機械1の制御装置は、ターンテーブル15を回転させて工作物の加工側面を回転工具32側に位置決めし、主軸31の回転用モータを駆動して回転工具32を回転開始する(図15のステップS1)。そして、旋回軸本体21Aのモータを駆動して旋回本体部22を回転し、主軸装置30を旋回させて回転工具32の回転位相を0度に割出し(図15のステップS2)、サドル13、旋回装置20及びスライドテーブル14をX,Y,Z軸線方向にそれぞれ直動させて工作物の一側面に孔を穿設する加工を開始する(図15のステップS3,S4)。   The control device of the machine tool 1 rotates the turntable 15 to position the processing side surface of the workpiece on the rotary tool 32 side, and drives the rotation motor of the spindle 31 to start rotating the rotary tool 32 (see FIG. 15). Step S1). Then, the motor of the revolving shaft main body 21A is driven to rotate the revolving main body portion 22, and the main spindle device 30 is revolved to index the rotational phase of the rotary tool 32 to 0 degree (step S2 in FIG. 15). The turning device 20 and the slide table 14 are moved linearly in the X, Y, and Z axis directions, respectively, to start a process of forming a hole in one side surface of the workpiece (steps S3 and S4 in FIG. 15).

このとき、主軸装置30の姿勢(回転軸線Rの向き)は、水平方向(0度)を向いているので、ラインガイド機構50の第一仕切り部材531の第一突状部材531b、第一羽部材551の第三突状部材55b、第二羽部材552の第三突状部材55b及び第二仕切り部材532の第二突状部材532bは、同一の回転角度に位置している。   At this time, since the attitude (the direction of the rotation axis R) of the spindle device 30 is oriented in the horizontal direction (0 degree), the first protruding member 531b of the first partition member 531 of the line guide mechanism 50 and the first blade The third protruding member 55b of the member 551, the third protruding member 55b of the second wing member 552, and the second protruding member 532b of the second partition member 532 are located at the same rotation angle.

よって、各領域A1−A3,B1−B3,B1−B3,A1−A3は、直線状に連通した形状、すなわち円筒形状を軸線方向に3分割した形状となっているので、各領域A1−A3,B1−B3,B1−B3,A1−A3を通る電気配線路26及び流体配管路28は、略直線状態となっている。   Therefore, each of the regions A1-A3, B1-B3, B1-B3, and A1-A3 has a shape communicating linearly, that is, a shape obtained by dividing a cylindrical shape into three in the axial direction. , B1-B3, B1-B3, and A1-A3, the electrical wiring path 26 and the fluid piping path 28 are substantially linear.

制御装置は、加工が終了したか否かを判断し(図15のステップS5)、本例では加工がまだ終了していないので、ステップS2に戻って旋回軸本体21Aのモータを駆動して旋回本体部22を回転し、主軸装置30を旋回させて回転工具32の回転位相を180度に割出す(図15のステップS2)。そして、サドル13、旋回装置20及びスライドテーブル14をX,Y,Z軸線方向にそれぞれ直動させて工作物の上面に孔を穿設する加工を開始する(図15のステップS3,S4)。   The control device determines whether or not the machining has been completed (step S5 in FIG. 15). In this example, since the machining has not been completed, the process returns to step S2 to drive the motor of the swing shaft main body 21A to turn. The main body unit 22 is rotated, and the spindle device 30 is turned to index the rotation phase of the rotary tool 32 to 180 degrees (step S2 in FIG. 15). Then, the saddle 13, the turning device 20, and the slide table 14 are linearly moved in the X, Y, and Z axis directions, respectively, to start a process of forming a hole in the upper surface of the workpiece (steps S3 and S4 in FIG. 15).

この回転位相割出中は、第二仕切り部材532の第二突状部材532bは、電気配線路26及び流体配管路28を回転方向に押圧し、電気配線路26及び流体配管路28は、第一羽部材551の第三突状部材55b及び第二羽部材552の第三突状部材55bを回転方向に押圧する。   During this rotation phase indexing, the second protruding member 532b of the second partition member 532 presses the electrical wiring path 26 and the fluid piping path 28 in the rotation direction, and the electrical wiring path 26 and the fluid piping path 28 The third protrusion 55b of the one blade 551 and the third protrusion 55b of the second blade 552 are pressed in the rotation direction.

これにより、第一羽部材551の領域B1−B3、第二羽部材552の領域B1−B3及び第二仕切り部材532の領域A1−A3は、徐々にずれて螺旋状になる。よって、電気配線路26及び流体配管路28は、局所的に急激なねじれを生じることはなく、破断や破損の発生を低減できる。   As a result, the region B1-B3 of the first wing member 551, the region B1-B3 of the second wing member 552, and the region A1-A3 of the second partition member 532 are gradually shifted to have a spiral shape. Therefore, the electric wiring path 26 and the fluid pipe path 28 do not locally generate a sharp twist, and can reduce the occurrence of breakage and breakage.

一方、ステップS5において、加工が終了した場合は、制御装置は、サドル13、旋回装置20及びスライドテーブル14をX,Y,Z軸線方向にそれぞれ直動させて回転工具32を退避位置に直動させるとともに、旋回本体部22を回転して主軸装置30を旋回させて回転工具32の回転位相を0度に割出す(図15のステップS6)。この回転位相割出中は、電気配線路26及び流体配管路28は、上述とは逆動作、すなわち螺旋を解く方向に旋回して直線状の状態に戻る。   On the other hand, when the machining is completed in step S5, the control device linearly moves the saddle 13, the turning device 20, and the slide table 14 in the X, Y, and Z axis directions, and linearly moves the rotary tool 32 to the retracted position. At the same time, the turning main body portion 22 is turned to turn the spindle device 30, and the rotation phase of the rotary tool 32 is indexed to 0 degrees (step S6 in FIG. 15). During the rotation phase indexing, the electric wiring path 26 and the fluid piping path 28 return to a linear state by reversing the operation described above, that is, turning in the direction in which the spiral is released.

よって、電気配線路26及び流体配管路28は、第一羽部材551、第二羽部材552及び第二仕切り部材532の内周との擦れによる摩擦抵抗等により、第一羽部材551、第二羽部材552及び第二仕切り部材532の内周に引き込まれたままで屈曲する事態を抑制でき、想定外の破断を防止できる。そして、主軸31の回転用モータを駆動停止して回転工具32を回転停止し(図15のステップS7)、全ての処理を終了する。   Therefore, the electric wiring path 26 and the fluid piping path 28 are caused by frictional resistance caused by rubbing against the inner circumferences of the first wing member 551, the second wing member 552, and the second partition member 532, and the like. It is possible to suppress bending while being drawn into the inner periphery of the wing member 552 and the second partition member 532, and to prevent unexpected breakage. Then, the drive of the rotation motor of the main shaft 31 is stopped to stop the rotation of the rotary tool 32 (step S7 in FIG. 15), and all the processes are ended.
