Description

本発明は、例えば旋盤やフライス盤あるいはターニング機能及びミーリング機能を有する複合5軸加工機(同時5軸制御可能なターニングセンター)に関するものである。   The present invention relates to, for example, a lathe, a milling machine, or a combined 5-axis machine having a turning function and a milling function (a turning center capable of simultaneous 5-axis control).

従来、旋盤やフライス盤,更には複雑な曲面加工が高能率に加工でき、立・横・斜めの穴加工,ねじ切り,ミーリング加工の多工程をもワンチャッキングで且つ標準工具で加工が可能であるターニング機能及びミーリング機能を有する立型の複合5軸加工機などが用いられているが、一般に旋盤やフライス盤では、ターニングテーブルに対して立設したコラムに横方向ガイド部としての水平クロスレールを上下動自在に設け、このクロスレールに沿ってX軸方向(左右方向)に移動自在に設けた刃物台に工具取付部を設けるか、又は前述のように左右方向及び上下方向に移動自在に設けたあるいは単に水平クロスレールに左右方向に移動自在に設けた刃物台を案内部として主軸を有するラムを上下動自在に設け、このラムの下端部に工具取付部を設けている。   Conventionally, lathes, milling machines, and even complex curved surfaces can be processed with high efficiency, and multiple processes such as vertical, horizontal, and slanted holes, threading, and milling can be performed with one chucking and with standard tools. Vertical compound 5-axis machines with turning and milling functions are used. Generally, in lathes and milling machines, horizontal cross rails are installed as horizontal guides on the column that stands up against the turning table. A tool mounting portion is provided on a tool post that is provided so as to be movable and is movable in the X-axis direction (left-right direction) along the cross rail, or is provided so as to be movable in the left-right direction and the up-down direction as described above. Alternatively, a ram having a spindle can be moved up and down with a tool post provided on a horizontal cross rail so as to be movable in the left-right direction, and a tool can be attached to the lower end of this ram. A is provided.

また、複合5軸加工機では、一般にコラムベッドに対してコラムをY軸方向(前後方向)に移動自在に設け、このコラムに横方向ガイド部としての水平クロスレールを、縦方向ガイド部としての縦クロスレールをガイドとしてZ軸方向(上下方向)に移動自在に設け、この水平クロスレールに沿ってX軸方向(左右方向)に刃物台を移動自在に設けるか、あるいは水平クロスレールにX軸方向に縦クロスレールを移動自在に設け、この縦クロスレールに刃物台を上下動自在に設ける構成、又は単に水平クロスレールに刃物台をX軸方向に移動自在に設け、この刃物台に主軸を設けたラムを上下動自在に設け、このラムの下端部に工具取付部を設ける構成とし、例えばこの工具取付部に左右方向に傾斜自在(B軸割出し自在)に工具を設けると共に、工具下方に位置するワークをセットするターニングテーブルを回転方向にC軸割出し自在に設け、工具をラム下端部の工具取付部にワンチャッキングするだけで、前記5軸の移動制御により、多工程の加工ができるように構成している。   Further, in a complex 5-axis machining apparatus, a column is generally provided so as to be movable in the Y-axis direction (front-rear direction) with respect to a column bed, and a horizontal cross rail as a lateral guide portion is provided on the column as a vertical guide portion. A vertical cross rail is provided as a guide so as to be movable in the Z-axis direction (vertical direction), and a tool post is provided to be movable in the X-axis direction (left-right direction) along the horizontal cross rail, or the horizontal cross rail is provided with an X-axis. A vertical cross rail is movably provided in the direction, and a tool post is provided on the vertical cross rail to be movable up or down, or a turret is simply provided on the horizontal cross rail so as to be movable in the X-axis direction. The provided ram is provided so as to be movable up and down, and a tool mounting portion is provided at the lower end of the ram. For example, when a tool is provided on the tool mounting portion so as to be tiltable in the left-right direction (B-axis indexing is possible). In addition, a turning table for setting a workpiece positioned below the tool is provided so that the C-axis can be freely indexed in the rotation direction. It is configured to allow multi-step processing.

しかしながら、Y軸方向の前後方向に傾斜自在(A軸割出し自在)若しくはX軸方向の左右方向に傾斜自在(B軸割出し自在)に工具を工具取付部に着脱自在に構成したものはあり、更に例えば他の工具(他の工具アタッチメント)と同様に交換可能にユニバーサルアタッチメントとして工具取付部に着脱自在に設けたものはあるが、このようにユニバーサルアタッチメントとして工具を割出し自在に設けたものは、旋回範囲は大きく取れず、まして360度回動することはできない。   However, there is a tool that can be attached to and detached from the tool mounting part so that it can be tilted in the front-rear direction in the Y-axis direction (A-axis indexable) or tilted in the left-right direction in the X-axis direction (B-axis indexable). In addition, for example, there are some universal attachments that can be attached to and detached from the tool mounting part in the same way as other tools (other tool attachments), but in this way the universal attachment can be indexed. The swivel range is not large, and it cannot be rotated 360 degrees.

即ち、割出し自在に工具を設けるユニバーサルアタッチメントは、ラム中心(主軸)とこれと連結する伝達回転軸中心(アタッチメント主軸)が一致しており、上下動自在に垂設したラムの下端部にA軸若しくはB軸割出し自在に工具を垂設するために360度回動は不能であり、また小型化できないために交換工具マガジンに自動交換自在にストックしておき交換装置によって自動交換することはできず、完全自動化ができる構成ではなかった。   In other words, the universal attachment with the indexable tool has a ram center (main shaft) and the transmission rotation shaft center (attachment main shaft) connected to the ram center. It is impossible to rotate 360 degrees to suspend the tool so that the shaft or B-axis can be indexed, and since it cannot be reduced in size, it can be automatically exchanged in the exchange tool magazine and exchanged automatically by an exchange device. It wasn't possible to make it fully automated.

工具7は、コラム2に対して刃物台5の移動あるいは例えばこれをガイドするラム8の移動によって工具取付部6が左右方向及び上下方向に移動し、更に各工具アタッチメント9のジョイント部としての前記工具取付部6に、ユニバーサルアタッチメントとして左右方向若しくは前後方向に回動自在な回動自在工具取付部10を設けた工具アタッチメント9を着脱自在に設け、この回動自在工具取付部10を回動駆動装置15により回動駆動してこの回動自在工具取付部10に設けた工具7をA軸若しくはB軸割出しする。   The tool 7 moves the tool mount 5 with respect to the column 2 or moves the ram 8 for guiding the tool 7 in the left-right direction and the up-down direction. Further, the tool 7 serves as a joint part of each tool attachment 9. A tool attachment 9 provided with a rotatable tool mounting portion 10 that is rotatable in the left-right direction or the front-rear direction as a universal attachment is detachably provided on the tool mounting portion 6, and the rotatable tool mounting portion 10 is driven to rotate. The tool 7 provided on the rotatable tool mounting portion 10 is rotated by the device 15 to index the A axis or the B axis.

従って、工具7を工具アタッチメント9の回動自在工具取付部10に装着し、この工具アタッチメント9を工具取付部6に装着すると、左右方向(X軸方向)及び上下方向(Z軸方向)に移動調整でき、更に回動自在工具取付部10を割出し回動(A軸割出し若しくはB軸割出し)して工具7の加工方向を首振り調整できる。   Accordingly, when the tool 7 is mounted on the rotatable tool mounting portion 10 of the tool attachment 9 and this tool attachment 9 is mounted on the tool mounting portion 6, it moves in the left-right direction (X-axis direction) and the vertical direction (Z-axis direction). Further, the rotation direction of the tool 7 can be adjusted by swinging the rotatable tool mounting portion 10 (A-axis indexing or B-axis indexing).

従って、例えばターニングテーブル1に対してコラム2をY軸方向に相対移動自在に設け、ターニングテーブル1を回転方向にC軸割出し自在に構成すれば、工具7を設ける回動自在工具取付部10を例えばB軸割出し自在とすることで、5軸を同時複合制御でき、複雑な曲面加工もでき、またこの工具7を回転工具として伝達回転させることで様々な面の様々な向きにミーリング加工も行えることとなる。   Therefore, for example, if the column 2 is provided so as to be relatively movable in the Y-axis direction with respect to the turning table 1, and the turning table 1 is configured so as to be indexable in the C-axis in the rotational direction, the rotatable tool mounting portion 10 on which the tool 7 is provided.

The rotatable tool mounting portion 10 is configured to be indexed and rotated 360 degrees on the side of the ram 8 around the horizontally disposed rotating shaft 14, and this rotatable tool. By mounting the indexing rotation driving device 15 for indexing and rotating the mounting portion 10 about the rotation axis 14 360 degrees on the tool attachment 9, and attaching the tool attachment 9 to the tool mounting portion 6.

It is configured to be able to rotate.

更に具体的に説明すると、工具取付部6は、主軸12を回転自在に内装したラム8の下端部に工具チャック部としてアタッチメント係合部6Aを設けた構成とし、このアタッチメント係合部6Aに工具アタッチメント9に設けたテーパシャンク部9Aを着脱自在に他の工具アタッチメント9と同様に、ラム8に内装したドローバ引き上げチャック装置18によって着脱自在にチャック固定し、更にこの工具アタッチメント9を自動工具交換装置によって交換自在に構成し、また回転工具7の場合は、主軸12に回動自在に連結するアタッチメント主軸13を伝達回転するように構成している。   More specifically, the tool mounting portion 6 has a configuration in which an attachment engaging portion 6A is provided as a tool chuck portion at the lower end portion of the ram 8 in which the main shaft 12 is rotatably mounted, and the tool engaging portion 6A is provided with a tool. The taper shank portion 9A provided on the attachment 9 is detachably fixed like the other tool attachments 9 by a drawbar pulling chuck device 18 built in the ram 8, and the tool attachment 9 is further attached to an automatic tool changer. In the case of the rotary tool 7, the attachment main shaft 13 that is rotatably connected to the main shaft 12 is configured to transmit and rotate.

また、この工具アタッチメント9に回動自在工具取付部10として回動ヘッド基体を回動軸14により軸支し、回動駆動装置15によって回動自在工具取付部10をX軸方向(左右方向)にB軸割出し制御自在に構成し、前記工具取付部6にチャックした工具アタッチメント9に対して360度首振り回動調整して360度加工角度を調整できる構成としている。   Further, a rotating head base is pivotally supported on the tool attachment 9 as a rotatable tool mounting portion 10 by a rotating shaft 14, and the rotating tool mounting portion 10 is moved in the X-axis direction (left-right direction) by a rotation driving device 15. B-axis indexing control is possible, and the 360-degree machining angle can be adjusted by swinging and rotating 360 degrees with respect to the tool attachment 9 chucked on the tool mounting portion 6.

また、主軸12に連結するアタッチメント主軸13は、回転軸伝達機構11を介して分取伝達回転軸16を伝達回転させるが、具体的には主軸12に連結するアタッチメント主軸13にベベルギア20を介して水平回転軸21を伝達回転させる構成としている。この水平回転軸21は360度B軸割出しする回動軸14を覆う筒状に構成し、更に設けたベベルギア20によって垂設した360度回動可能な分取伝達回転軸16を伝達回転するように構成し、主軸12と分取伝達回転軸16とを側方へズラしてラム8の側方でこの分取伝達回転軸16に設けた回動自在工具取付部10を360度回動できるように構成している。   Further, the attachment main shaft 13 connected to the main shaft 12 transmits and rotates the sorting transmission rotation shaft 16 via the rotation shaft transmission mechanism 11. Specifically, the attachment main shaft 13 connected to the main shaft 12 via the bevel gear 20 is rotated. The horizontal rotation shaft 21 is configured to transmit and rotate. The horizontal rotating shaft 21 is formed in a cylindrical shape covering the rotating shaft 14 for indexing the 360-degree B-axis, and further rotates a preparative transmitting rotating shaft 16 that can be rotated 360 degrees by a bevel gear 20 provided. The main shaft 12 and the sorting transmission rotating shaft 16 are shifted laterally, and the rotatable tool mounting portion 10 provided on the sorting transmission rotating shaft 16 is rotated 360 degrees on the side of the ram 8. It is configured to be able to.

また、この分取伝達回転軸16を工具取付部6と同様にベアリングで支承し、この分取伝達回転軸16に工具取付部6と同様にアタッチメント係合部10Aを設けると共に、ドローバ引き上げチャック装置18を内装しこれにより工具アタッチメント9のテーパシャンク部9Aを着脱自在にチャック固定する回転自在工具取付部10を構成し、この回転自在工具取付部10を回動軸14を支軸としてベベルギア20によって分取伝達回転軸16を伝達回転できる状態を維持しつつ360度回動自在に構成している。従って、主軸12を回転すれば首振り回動する回動自在工具取付部10のアタッチメント係合部10Aにチャックした交換工具7を伝達回転できるように構成している。   Further, the sorting transmission rotating shaft 16 is supported by a bearing in the same manner as the tool mounting portion 6, and an attachment engaging portion 10A is provided on the sorting transmission rotating shaft 16 similarly to the tool mounting portion 6, and a drawbar pulling chuck device is provided. A rotatable tool mounting portion 10 is configured to detachably chuck and fix the taper shank portion 9A of the tool attachment 9 by the bevel gear 20 with the rotating shaft 14 as a support shaft. The preparative transmission rotating shaft 16 is configured to be able to rotate 360 degrees while maintaining a state where it can be transmitted and rotated. Therefore, when the main shaft 12 is rotated, the replacement tool 7 chucked on the attachment engaging portion 10A of the rotatable tool mounting portion 10 that swings and rotates can be transmitted and rotated.

また、本実施例では、回転自在工具取付部10を割出し回動した位置を固定ロックするための回動ロック装置を備えている。具体的には工具アタッチメント9の回転自在工具取付部10と反対側の回動駆動装置15を搭載したボックスに回動ロック装置として、例えばロック用エアシリンダ装置24を設けると共に、このエアシリンダ装置24の駆動によってカービックカップリング25が作動締め付けして回動軸14の回動位置を固定するように構成している。   In this embodiment, a rotation lock device is provided for fixing and locking the position where the rotatable tool mounting portion 10 is indexed and rotated. Specifically, for example, a lock air cylinder device 24 is provided as a rotation lock device in a box on which a rotation drive device 15 opposite to the rotatable tool mounting portion 10 of the tool attachment 9 is mounted. With this driving, the Curbic coupling 25 is operated and tightened to fix the rotation position of the rotation shaft 14.

このように自動工具交換装置によって工具取付部6に工具アタッチメント9を交換装着することでB軸割出しにより工具7の向きを首振り回動調整でき、しかもこの回動自在工具取付部10はラム8の側面に干渉しない側方位置で回動するため360度のB軸割出しが可能となる。従って、水平クロスレール3に対して移動する刃物台5に対してラム8が上下動し、工具7は更にこのX軸・Z軸及びコラム2によるY軸移動並びにターニングテーブル1のC軸割出しに加えて、360度B軸割出しできるため、様々な面に様々な向きで加工が自在に行える。   As described above, the tool attachment 9 is exchanged and mounted on the tool mounting portion 6 by the automatic tool changer, so that the direction of the tool 7 can be swung and adjusted by the B-axis indexing. Since it rotates at a side position that does not interfere with the side surfaces of the B, 360-degree B-axis indexing is possible. Accordingly, the ram 8 moves up and down with respect to the tool post 5 moving with respect to the horizontal cross rail 3, and the tool 7 further moves the X axis and Z axis, the Y axis by the column 2, and the C axis index of the turning table 1. In addition, since the 360-degree B-axis can be indexed, it can be freely processed in various directions on various surfaces.

また、工具取付部6を旋削工具用のみとして単に工具取付部6を回動自在に設けたタレットヘッドに構成して、例えばこの工具取付部6の回動制御によって様々な旋削工具に切り換えたり加工角度を調整できるようにしても良いが、本実施例のユニバーサルアタッチメント(回動自在工具取付部10を有する回動駆動装置15付の工具アタッチメント9)を交換装着すれば、360度割出しして広範囲に加工方向を首振り変更設定でき、勿論ミーリング機能も維持されて回転工具7を伝達回転させて360度あらゆる方向へミーリング加工も行えることとなる。従って、これにより5軸複合加工が行える構成でありながら小径の内径加工が行え、しかも小型化可能な構成によって自動交換が行え、移動制御も工具交換制御も容易に設計できるユニバーサルアタッチメントであって且つ360度の広範囲な割出しも行える極めて画期的な工作機械となる。   Further, the tool mounting portion 6 is used only for a turning tool, and is simply configured as a turret head in which the tool mounting portion 6 is rotatably provided. For example, the tool mounting portion 6 can be switched to various turning tools by rotating control of the tool mounting portion 6. Although the angle may be adjustable, if the universal attachment (tool attachment 9 with the rotation drive device 15 having the rotatable tool mounting portion 10) of this embodiment is exchanged and mounted, it will be indexed 360 degrees. The machining direction can be changed over a wide range, and of course, the milling function is maintained, and the rotary tool 7 is transmitted and rotated to perform milling in any direction of 360 degrees. Therefore, this is a universal attachment that can perform 5-axis combined machining, can perform small-diameter inner diameter machining, can be automatically changed by a structure that can be downsized, and can easily design movement control and tool change control. It will be an extremely innovative machine tool that can perform indexing over a wide range of 360 degrees.
