Description

本発明は主にブローチによる切削加工を行うのに適した加工装置に関する。   The present invention mainly relates to a processing apparatus suitable for performing cutting with a broach.

従来、旋盤の主軸に装着される回転体と、この回転体の中心に貫通され設けられた該回転体と一体的に回転する雌ネジ部からなる回転螺旋送り部と、この回転螺旋送り部に螺合させて該回転螺旋送り部の回転動作により直線移動を行う雄ネジ部が螺刻された直線移動棒体と、この直線移動棒体の端に設けられたブローチ刃を装着する切削具装着部とからなる加工装置が知られている（例えば特許文献１）。   Conventionally, a rotating body mounted on the main shaft of a lathe, a rotating spiral feed portion comprising a female thread portion that rotates integrally with the rotating body that is provided through the center of the rotating body, and a rotating spiral feeding portion Cutting tool mounted to mount a linearly moving rod body threaded with a male threaded portion that is screwed and moved linearly by the rotational movement of the rotating spiral feed portion, and a broach blade provided at the end of the linearly moving rod body 2.

また、直線移動棒体を回転体のみに支持した状態で、直線移動案内部の位置あわせ（芯だし）を行わなければならないために、位置合わせがし難いという欠点を有するものであった。
特開２００４−１０６１６６号公報 特に無し Accordingly, when the length of the main shaft of the linear moving rod body in the main shaft tunnel and the protruding portion from the main shaft tunnel becomes long, the linear moving rod body is shaken or bent due to the weight of the linear moving rod body and the driving vibration of the device, thereby The moving rod body and the broaching blade attached to the moving rod body also suffer from the adverse effect of being shaken or bent, and have the disadvantage that the cutting accuracy is reduced.
In addition, since the linear movement guide portion must be aligned (centered) in a state where the linear moving rod is supported only by the rotating body, there is a drawback that it is difficult to align.

The linear movement guide body 22 is formed.

加工装置１の装置本体２０は、駆動装置２の主軸１０の主軸端部７にボルト２５によって固定される回転体２６と、この回転体２６の中心に貫通され設けられた該２６と一体的に回転する雌ネジ部からなる回転螺旋送り部２７と、この回転螺旋送り部２７に螺合して該２７の回転により直線移動を行う直線移動棒体２８と、この直線移動棒体２８の外周に螺刻された回転螺旋送り部２７に螺合する雄ネジ部（角ネジが好ましい）からなる非回転螺旋部２９と、直線移動棒体２８の回転体２６の端部に設けられた主に切削具であるブローチ刃３０を装着する切削具装着部３１と、直線移動棒体２８の長手方向に直線的に溝形態で設けられた直線案内軌条部３２と、この直線案内軌条部３２に嵌って直線移動棒体２８の回転を阻止して該直線移動棒体２８の直線移動動作を実現する嵌り凸部３３を有するとともに、駆動装置２の刃物台１２に横に突出した固定部位３４を挟持させて固定される直線移動案内部３５と、直線移動棒体２８の左右に設けられた回転螺旋送り部２７と非回転螺旋部２９との螺合が解除されてそれ以上の移動動作を止める螺合解除部３８、３９と、主軸トンネル部１１側に位置する螺合解除部３８の端にボルト４０で固定された固定駒４１の外周に設けられた回転動作対応の、直線移動支持手段であるリニアベアリング４２とからなっている。

As the feed movement (left movement) of the body 28 progresses, the movable piece 46 hits and moves against the spindle end portion 7 and finally the entire rotation spiral feed portion 27 enters the thin rod portion 45, so that the 27 does not rotate. The unscrewed state with the spiral portion 29 is released, and the further movement of the linear moving rod 28 is stopped. When the rotating spiral feeding portion 27 is rotated in the reverse direction (pull rotation = left movement), the rotating spiral feeding portion 27 and the non-rotating spiral portion 29 are quickly screwed together by being pushed by the pressing force of the compression coil spring 47, and a linearly moving rod body. 28 becomes a pulling movement operation state.

（発明を実施するための異なる形態）
次に、図６ないし図８に示す本発明を実施するための異なる形態について説明する。なお、これら本発明を実施するための異なる形態の説明に当たって、本発明を実施するための最良の第１の実施の形態と同一構成部分には同一符号を付して重複する説明を省略する。 (Different modes for carrying out the invention)
Next, different modes for carrying out the present invention shown in FIGS. 6 to 8 will be described. In the description of the different modes for carrying out the present invention, the same components as those in the best first embodiment for carrying out the present invention are denoted by the same reference numerals, and redundant description is omitted.

図６に示す本発明を実施するための最良の第２の実施の形態において前記第１の実施の形態と主に異なる点は、リニアベアリング４２を可動駒４６の外周に設けた構成としたもので、このような構成としても前記第１の実施の形態と同様な効果を得ることができる。   6 differs from the first embodiment mainly in that the linear bearing 42 is provided on the outer periphery of the movable piece 46. The second embodiment shown in FIG. Thus, even with such a configuration, the same effects as those of the first embodiment can be obtained.

図７に示す本発明を実施するための最良の第３の実施の形態において前記第１の実施の形態と主に異なる点は、リニアベアリング４２が主軸トンネル部１１の内壁に当接移動するような形態とし、主軸延長部９を駆動装置２の外に突き出させて長くした形態とした点である。
このような構成としても前記第１の実施の形態と同様な効果を得ることができる。 In the third preferred embodiment for carrying out the present invention shown in FIG. 7, the main difference from the first embodiment is that the linear bearing 42 moves in contact with the inner wall of the main shaft tunnel portion 11. The main shaft extension 9 is protruded out of the drive device 2 and lengthened.
Even with such a configuration, the same effects as those of the first embodiment can be obtained.

図８に示す本発明を実施するための最良の第４の実施の形態において前記第１の実施の形態と主に異なる点は、直線移動案内体２２の先端側を回転体２６側に近い部位に設けたベアリング７５で回転自在に軸受けし、反対側を主軸台５に複数本のボルト７６で固定した固定部材７７にボルト７８で回転不能に支持してなる点である。
直線移動案内体２２は回転しないので、リニアベアリング４２には回転動作は生じなく直線移動のみとなるので、リニアベアリング４２の長寿命化とより高精度な支持を実現する。 The fourth preferred embodiment for carrying out the present invention shown in FIG. 8 is mainly different from the first embodiment in that the tip end side of the linear movement guide body 22 is close to the rotating body 26 side. The bearing 75 is rotatably supported by a bearing 75, and the opposite side is supported by a bolt 78 so as to be non-rotatable by a fixing member 77 fixed to the headstock 5 by a plurality of bolts 76.
Since the linear movement guide body 22 does not rotate, the linear bearing 42 does not rotate and only moves linearly, so that the life of the linear bearing 42 is extended and more accurate support is realized.
