Description

本発明は、スピニング加工装置に関し、特に、回転不能に支持した被加工部材に対し、ローラを公転駆動してスピニング加工を行うスピニング加工装置に関するものである。   The present invention relates to a spinning processing apparatus, and more particularly to a spinning processing apparatus that performs a spinning process by driving a roller to revolve with respect to a workpiece that is supported so as not to rotate.

主に管素材の端部に対してスピニング加工を行って、例えば、テーパ状の管端部を形成するスピニング加工装置として、種々の形式のものが知られている(例えば、特許文献1〜3参照。)。
このうち、特許文献1に記載のものは、被加工部材を回転不能に支持した状態で絞り工具を被加工部材の回りに公転駆動してスピニング加工を行うようにしている。
この主軸装置は、2重構造の主軸にカム板と工具取付台(面板)を設け、主軸後方に直列に装着した2組の遊星歯車機構を駆動し、回転中の主軸の内外管の間に速度差を生起させてカム板と工具取付台との間に相対回動を与え、主軸回りを公転する絞り工具を、径方向に摺動させてスピニング加工を行うように構成されている。
For example, various types of spinning processing apparatuses that form a tapered pipe end by spinning the end of the tube material are known (for example, Patent Documents 1 to 3). reference.).
Among them, the one described in Patent Document 1 performs spinning by rotating the drawing tool around the workpiece while the workpiece is supported so as not to rotate.
This spindle device is provided with a cam plate and a tool mounting base (face plate) on a dual-structure spindle, drives two planetary gear mechanisms mounted in series behind the spindle, and between the inner and outer pipes of the rotating spindle. A speed difference is caused to cause relative rotation between the cam plate and the tool mounting base, and a drawing tool that revolves around the spindle is slid in the radial direction to perform spinning.

また、特許文献2〜3に記載のものは、傾斜軸及び偏心軸を適宜組み合わせ、被加工部材回りに加工具であるローラを公転駆動してスピニング加工を行うようにしている。   In addition, in the ones described in Patent Documents 2 to 3, a tilting shaft and an eccentric shaft are appropriately combined, and a spinning process is performed by driving a roller as a processing tool around the workpiece to be rotated.

しかしながら、特許文献1に記載の主軸装置のように、主軸回りを公転する加工具によってスピニング加工を行う装置においては、加工具を固定して被加工部材を回転させるスピニング加工装置とは異なり、例えば、絞り工具及び切断を行う刃具といった複数の種類の加工具を並設して加工することが困難であるため、スピニング加工終了後に、別工程で別の設備を用いて加工端部の切断を行う必要があった。
このようなスピニング加工後の切断工程は、特許文献2〜3に記載されているような傾斜軸や偏心軸を含むスピニング加工を行った後には、管端部の仕上げ加工として必須の工程となる。
また、主軸回りを公転する加工具によってスピニング加工を行う装置において、例えば、2種類のローラを用いて連続してスピニング加工を行い得るようにすることが要請されているが、特許文献1〜3に記載のものでは実現できなかった。
However, unlike the spindle device described in Patent Document 1, an apparatus that performs spinning with a processing tool that revolves around the spindle is different from a spinning device that fixes a processing tool and rotates a workpiece, for example, Since it is difficult to process a plurality of types of processing tools such as a drawing tool and a cutting tool that are arranged in parallel, the processing end is cut in a separate process using another equipment after the spinning process is completed. There was a need.
Such a cutting process after the spinning process is an indispensable process for finishing the pipe end after performing the spinning process including the inclined shaft and the eccentric shaft as described in Patent Documents 2 to 3. .
In addition, in an apparatus that performs a spinning process using a processing tool that revolves around the main shaft, for example, it is required that the spinning process can be performed continuously using two types of rollers. It could not be realized with the one described in 1.

ところで、本件出願人らは、先に、回転不能に支持した被加工部材に対し、加工具を公転駆動してスピニング加工を行うスピニング加工装置において、スピニング加工を適切に行うとともに、スピニング加工に連続して切断等の他の加工を行い得るスピニング加工装置を提案した(特許文献4参照。)。
このスピニング加工装置は、内管及び外管の二重管からなる主軸と、前記外管の先端部に設け前記外管の軸を中心に前記外管と共に回転する第1の回転体と、該第1の回転体と平行に前記内管の先端部に設け前記内管の軸を中心に前記内管と共に回転する第2の回転体であって、前記内管の軸回りに第1の案内路及び第2の案内路を形成した第2の回転体と、該第2の回転体の前記第1の案内路及び第2の案内路に沿って夫々移動可能に、前記第1の回転体に支持する第1の加工具及び第2の加工具と、前記内管及び前記外管を同方向に回転駆動し、かつ、必要に応じて前記内管と前記外管との間に回転差が生起されるように前記内管及び前記外管を相対的に回転駆動する駆動手段とを備え、前記第2の回転体が一方向に回転するとき前記第1の加工具と前記第2の加工具が相対的に逆方向に移動するように前記第1の案内路及び第2の案内路を形成し、回転不能に支持した被加工部材に対し、前記第1の加工具及び第2の加工具を公転駆動しながら、前記第1の加工具を前記第1の案内路に沿って径方向に駆動するとともに、前記第2の加工具を前記第2の案内路に沿って径方向に駆動するように構成されている。
By the way, the applicants of the present application, in a spinning processing apparatus that performs spinning processing by revolving a processing tool on a workpiece that is supported in a non-rotatable manner, performs spinning processing appropriately and continues to spinning processing. Thus, a spinning processing apparatus capable of performing other processing such as cutting has been proposed (see Patent Document 4).
The spinning device includes a main shaft composed of a double tube of an inner tube and an outer tube, a first rotating body that is provided at a distal end portion of the outer tube and rotates with the outer tube around the axis of the outer tube, A second rotating body provided at the tip of the inner tube in parallel with the first rotating body and rotating together with the inner tube about the axis of the inner tube, the first guide around the axis of the inner tube A second rotating body that forms a path and a second guide path, and the first rotating body is movable along the first guide path and the second guide path of the second rotating body, respectively. The first processing tool and the second processing tool supported on the inner tube and the outer tube are rotated in the same direction, and if necessary, a rotational difference between the inner tube and the outer tube. Drive means for relatively rotating the inner tube and the outer tube so that the second rotating body rotates in one direction. The first guide path and the second guide path are formed so that the processing tool and the second processing tool move relatively in the opposite directions, and the workpiece is supported in a non-rotatable manner. While the first processing tool and the second processing tool are driven to revolve, the first processing tool is driven in the radial direction along the first guide path, and the second processing tool is moved to the second processing tool. It is configured to drive in the radial direction along the guide path.

And a link mechanism 53 having two link pieces 53b.

この場合において、回転駆動軸1は、中空軸で構成し、その内部に中空軸で構成した第1のシャフト6を挿通し、さらに、その内部に中実軸で構成した第2のシャフト7を挿通するようにしている。
第1のシャフト6は、基端側をシリンダ機構61に接続し、回転駆動軸1と独立して、軸方向に移動可能に設けられるとともに、先端側にマンドレル62を取り付けるようにしている。
また、第2のシャフト7は、基端側をシリンダ機構71に接続し、回転駆動軸1及び第1のシャフト6と独立して、軸方向に移動可能に設けられるとともに、先端側がマンドレル62を貫通させることによって、加工したワークをマンドレル62から離脱できるようにしている。
In this case, the rotary drive shaft 1 is constituted by a hollow shaft, a first shaft 6 constituted by a hollow shaft is inserted into the inside thereof, and a second shaft 7 constituted by a solid shaft is inserted therein. I try to insert it.

By passing through, the processed workpiece can be detached from the mandrel 62.

移動体の位置制御機構52は、移動体51に軸受を介して回転自在に、かつ、回転駆動軸1の軸方向に不動に配設された操作体52aと、操作体52aを回転駆動軸1と平行な方向に駆動するボールねじ機構52b及びサーボモータ52c等からなる駆動機構とからなる。   The moving body position control mechanism 52 includes an operating body 52a that is rotatably disposed on the moving body 51 via a bearing and that is immovable in the axial direction of the rotary drive shaft 1; And a drive mechanism including a ball screw mechanism 52b and a servo motor 52c that are driven in a direction parallel to the motor.

リンク機構53の第1のリンク片53a及び第2のリンク片53bは、移動体51に設けたピン51a、51bと、第1の加工具4a及び第2の加工具4bに設けたピン41a、41bとを介して、移動体51と第1の加工具4a及び第2の加工具4bとをそれぞれ接続するように構成されている。   The first link piece 53a and the second link piece 53b of the link mechanism 53 include pins 51a and 51b provided on the moving body 51, and pins 41a provided on the first processing tool 4a and the second processing tool 4b.

これにより、回転駆動軸1の軸心から第1の加工具4a及び第2の加工具4bの図1の実線で示す径方向の外周側の待避位置までの距離を必要最小限に設定することができ、第1の加工具4a及び第2の加工具4bの遠心力による回転駆動軸1のブレを小さくすることができる。
In addition, the first processing piece 4a and the second processing tool 4b are not moved by the movement of the moving body 51 to the first link piece 53a and the second link piece 53b of the link mechanism 53 ("play" portion). In the present embodiment, long holes 54a and 54b) through which pins 51a and 51b provided on the moving body 51 are inserted are provided.
Thereby, the distance from the axial center of the rotary drive shaft 1 to the retracted position on the outer peripheral side in the radial direction shown by the solid line in FIG. 1 of the first processing tool 4a and the second processing tool 4b is set to the minimum necessary. The vibration of the rotary drive shaft 1 due to the centrifugal force of the first processing tool 4a and the second processing tool 4b can be reduced.
