この考案は、マシニングセンタなどの工作機械の回転主軸に取り付けられ、主 軸の回転に伴ってその先端に取り付けられた工具に往復運動とスパイラル運動を 同時に与えてラッピングやホーニング加工を可能とした工具保持具に関する。 This device is attached to the rotating spindle of a machine tool such as a machining center, and the tool attached to the tip of the spindle as the spindle rotates reciprocates and spirals at the same time to enable lapping and honing.

マシニングセンタなどの工作機械においては、回転主軸に取り付けられた工具 保持具の回転を阻止し、該工具保持具の摺動軸に設けたカム溝に工具保持具本体 から突設したローラを係合して、該摺動軸の先端に取り付けた工具に軸方向のス トローク運動を与えてスロッティング加工を行わせるものが従来からあった（例 えば実開昭５９−１００５３８号公報参照）。 In machine tools such as machining centers, the rotation of a tool holder attached to a rotary spindle is prevented, and a roller protruding from the tool holder body is engaged with a cam groove provided on the sliding shaft of the tool holder. In the past, a tool attached to the tip of the sliding shaft was given a stroking motion in the axial direction to perform slotting (see, for example, Japanese Utility Model Laid-Open No. 59-100538).

しかし、ラッピング加工やホーニング加工、あるいはヤスリ仕上げ加工では、 往復運動とスパイラル運動を同時に行うことが必要であるが、上記のごとく従来 品では軸方向のストローク運動のみが可能であった。このために、マシニングセ ンタでは、往復運動とスパイラル運動を同時に与えて加工を行うことは出来なか った。 However, in lapping, honing, and file finishing, it is necessary to perform reciprocating motion and spiral motion at the same time, but with the conventional products, only stroke motion in the axial direction was possible as described above. For this reason, it was not possible to perform reciprocating motion and spiral motion at the same time in machining centers.

図示しないマシニングセンタなどの工作機械の主軸を回転させると、本体Ａは 固定部Ｂにより支持されながら回転するが、本体の長手方向の穴に挿入された摺 動軸は前記の穴に設けられた板状円筒カムの正弦曲線に沿って回転するローラに 沿って往復動し、さらに摺動軸に取り付けられた回転止めローラが、固定側に取 り付けられた調整筒の内周面に形成されたねじれ溝に案内されてスパイラル運動 を行うことになり、摺動軸の先端に取り付けられた工具が回転しながら往復して ホーニング加工あるいはラップ加工がなされる。 When the main shaft of a machine tool such as a machining center (not shown) is rotated, the main body A rotates while being supported by the fixed portion B, but the sliding shaft inserted into the longitudinal hole of the main body is the plate provided in the hole.

次に、この考案の実施例を図面により説明する。この考案に係る工具保持具は 図１において、一端に図示しない工作機械の回転主軸に取り付けられるシャンク １を有する本体Ａと、これを回転自在に支承する固定部Ｂとから構成される。本 体Ａは、上記のとおりシャンク１を後端に有し、前端に開口する長手方向の穴１ ８が穿設されていて、該長手方向の穴１８には摺動筒３が後述する蓋５の内周に 設けられた摺動軸受１１ａと本体の円筒部１９の内方に設けられた摺動軸受１１ ｂを介して軸方向にのみ移動可能に挿通されている。さらに、摺動軸３の先端に はホーニング砥石あるいはラップ加工用工具などの工具８が取り付けられている 。 Next, an embodiment of this invention will be described with reference to the drawings. The tool holder according to the present invention comprises, in FIG. 1, a main body A having a shank 1 attached to a rotary spindle of a machine tool (not shown) at one end, and a fixing portion B for rotatably supporting the shank 1. The main body A has the shank 1 at the rear end as described above, and has a longitudinal hole 18 opened at the front end, and the sliding cylinder 3 is provided in the longitudinal hole 18 as described later. 5 is inserted through a sliding bearing 11a provided on the inner circumference and a sliding bearing 11b provided inside the cylindrical portion 19 of the main body so as to be movable only in the axial direction. Further, a tool 8 such as a honing stone or a lapping tool is attached to the tip of the sliding shaft 3.
【０００７】 前記本体Ａの長手方向の穴１８の内壁面２０には、軸方向の端面７ａ，７ｂが 正弦曲線で形成されてカム面を構成する板状円筒カム７がボルト２１によって取 り外し可能に取り付けられており、前記の摺動軸３の外面に突設された一対のロ ーラ軸１７ａ，１７ｂによって回転可能に支持されたローラ６ａ，６ｂは板状カ ム円筒７のカム面である端面７ａ，７ｂに接触する。このために、本体の回転に 伴って該カム面に沿ってローラ６ａ，６ｂが回転することにより、正弦曲線にそ って摺動軸３を長手方向に往復動を可能とする。On the inner wall surface 20 of the hole 18 in the longitudinal direction of the main body A, the plate-shaped cylindrical cam 7 forming the cam surface with axial end surfaces 7 a and 7 b formed in a sine curve is removed by the bolt 21. The rollers 6a and 6b, which are rotatably supported by a pair of roller shafts 17a and 17b protrudingly provided on the outer surface of the sliding shaft 3, are cam surfaces of the plate-shaped cam cylinder 7. To the end surfaces 7a and 7b. Therefore, as the main body rotates, the rollers 6a and 6b rotate along the cam surface, thereby enabling the sliding shaft 3 to reciprocate in the longitudinal direction along a sine curve.
【０００８】 固定部Ｂは、図示しない工作機械の固定側の係合穴に挿着して固定される位置 決めピン１０を突設したハウジング２を有し、さらに該ハウジングは本体Ａの円 筒部１９との間に設けられた軸受１２ａ，１２ｂを介して本体Ａを回転可能に支 承する。ハウジング２から突き出た摺動軸３を囲むように図２、図３に示すよう な内周面に所定のねじれ角をもつねじれ溝１５が形成された調整筒４がボルト２ ２によりハウジング２に取り付けられている。The fixing portion B has a housing 2 protruding from a positioning pin 10 which is inserted and fixed in an engagement hole on a fixed side of a machine tool (not shown), and the housing is a cylinder of the main body A. The main body A is rotatably supported via bearings 12a and 12b provided between the main body A and the portion 19. An adjusting cylinder 4 having a spiral groove 15 having a predetermined spiral angle on the inner peripheral surface as shown in FIGS. 2 and 3 so as to surround the sliding shaft 3 protruding from the housing 2 is attached to the housing 2 by a bolt 22. It is installed.
【０００９】 さらに、前記のねじれ溝１５に係合して回転し、摺動軸３をスパイラル運動さ せるローラ９を保持する軸２３が前記摺動軸３に突設されている。前記調整筒４ には、前記のようにさらに蓋５が取り付けられ、内周面に設けられた段部２４に 組み込まれた摺動軸受１１ａを介して摺動軸３をガイドしている。かくて、摺動 軸３はねじれ溝１５に沿って正確にスパイラル運動などの回転運動を往復運動と 共に行うことができるのである。Further, a shaft 23, which holds the roller 9 that engages with the twist groove 15 and rotates to make the sliding shaft 3 spirally move, is provided so as to project from the sliding shaft 3. The lid 5 is further attached to the adjusting cylinder 4 as described above, and the sliding shaft 3 is guided through the sliding bearing 11a incorporated in the step portion 24 provided on the inner peripheral surface. Thus, the sliding shaft 3 can accurately perform a rotary motion such as a spiral motion along with the reciprocating motion along the twist groove 15.
【００１０】 摺動軸３の後端にはボルト２５がねじ込まれていて、本体Ａのシャンク内方に 形成された段部２６と前記ボルトの頭部２７との間にコイルバネ１３が介装され ており、板状円筒カム７とローラ６ａ，６ｂとの間に小さなすき間により発生す るローラ軸１７ａ，１７ｂにかかる衝撃を緩和するために摺動軸３を機械主軸側 に引き寄せることになる。A bolt 25 is screwed into the rear end of the sliding shaft 3, and a coil spring 13 is interposed between a step portion 26 formed inside the shank of the main body A and a head portion 27 of the bolt. Therefore, the sliding shaft 3 is pulled toward the main shaft of the machine in order to reduce the impact applied to the roller shafts 17a and 17b caused by the small gap between the plate-shaped cylindrical cam 7 and the rollers 6a and 6b.
【００１１】 さらに、板状円筒カム７を取り替えてカム形状を変えることにより、往復に要 する速度、あるいは変位量１６を変えることも可能である。また、前記のスパイ ラル運動を与えるねじれ溝１５は、その角度、リードなどを自由に変えて運動量 を変えることも可能である。Furthermore, by changing the cam shape by replacing the plate-shaped cylindrical cam 7, it is possible to change the speed required for reciprocation or the displacement amount 16. Further, the twist groove 15 that gives the spiral movement can also change the amount of movement by freely changing the angle, the lead, and the like.
【００１２】[0012]
【効果】 この考案は、上記のように摺動軸に突設されたローラが本体の内壁面に着脱可 能に取り付けられ、正弦曲線で構成された板状円筒カムのカム面に沿って摺動軸 が往復動すると共に、固定側に取り付けられた調整筒の内周面に形成されたねじ れ溝に沿ってスパイラル運動するので、ホーニング加工あるいはラップ加工を行 うことが可能になり、マシニングセンタ等の工作機械において極めて能率的な加 工が可能となった。[Effect] According to the present invention, the roller protruding from the sliding shaft is detachably attached to the inner wall surface of the main body as described above, and slides along the cam surface of the plate-shaped cylindrical cam having a sinusoidal curve. Since the moving shaft reciprocates and also makes a spiral motion along the spiral groove formed on the inner peripheral surface of the adjustment cylinder attached to the fixed side, honing or lapping can be performed, and the machining center It has become possible to perform extremely efficient machining on machine tools such as.

しかし、ラッピング加工やホーニング加工、あるいはヤスリ仕上げ加工では、 往復運動とスパイラル運動を同時に行うことが必要であるが、上記のごとく従来 品では軸方向の直線ストローク運動のみが可能であった。このために、マシニン グセンタでは、往復運動とスパイラル運動を同時に与えて加工を行うことは出来 なかった。However, in lapping, honing, or file finishing, it is necessary to perform both reciprocating motion and spiral motion at the same time, but as described above, conventional products were capable of only linear stroke motion in the axial direction. For this reason, it was not possible to perform reciprocating motion and spiral motion at the same time in the machining center.
