Abstract

<P>PROBLEM TO BE SOLVED: To enable not only constant-speed diameter expanding control of a grinding wheel 12 but also constant-pressure diameter expanding control with fine accuracy while suppressing a rise in costs of a device by devising the structure of a rod 2 for expanding a diameter by pushing out the grinding wheel 12 in a honing tool B. <P>SOLUTION: The rod 2 is divided into two of a rod main body 21 on the front end side and a base end member 20, and the two are rotated integrally with a coil spring 23 interposed therebetween and connected movably by a prescribed amount in the axial direction. The base end member 20 is moved by a lifting device 3, thereby making a changeover between an indirect condition in which it transmits a force in the axial direction to the rod main body 21 via the coil spring 23 and a direct condition (shown in Fig. 2) in which it is connected to the rod main body 21 directly without interposition of the coil spring 23. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

本発明は、ワークの内周面をホーニング加工するための装置に関し、特に、回転軸に取り付けられるホーニングツールの構造に係る。   The present invention relates to an apparatus for honing an inner peripheral surface of a workpiece, and particularly relates to a structure of a honing tool attached to a rotating shaft.

従来より、この種のホーニング加工装置に使用されるホーニングツールは、一般的に、複数の砥石が周方向に並んだ円筒状の砥石ホルダを備えている。本発明の実施形態である図1を利用して具体的に説明すると、砥石ホルダには、径方向の貫通穴(1a,1a,…)が周方向に亘って略等間隔に設けられ、その各々に砥石(12)を固定した砥石装着部材(11,11,…)が径方向に進退可能に保持されている。   Conventionally, a honing tool used in this type of honing apparatus generally includes a cylindrical grindstone holder in which a plurality of grindstones are arranged in the circumferential direction. Specifically, referring to FIG. 1 which is an embodiment of the present invention, the grindstone holder is provided with radial through holes (1a, 1a,...) At substantially equal intervals in the circumferential direction. A grindstone mounting member (11, 11,...) Having a grindstone (12) fixed thereto is held so as to be able to advance and retreat in the radial direction.

また、砥石ホルダの内部には、ロッド(2)の先端側に形成されたテーパ状の押出部(21a)が軸方向に変位可能に挿入される一方、これを囲む前記砥石装着部材(11,11,…)の内側面が対応するテーパ状に形成されており、そのロッド(2)を先端側に相対移動させることで、砥石装着部材(11,11,…)がそれぞれ径方向外方に押し出されて、砥石径が拡大するようになっている。   Further, inside the grindstone holder, a tapered extruded portion (21a) formed on the tip side of the rod (2) is inserted so as to be displaceable in the axial direction, while surrounding the grindstone mounting member (11, 11, ...) is formed in a corresponding tapered shape, and by moving the rod (2) relative to the tip side, the grindstone mounting members (11, 11, ...) are each radially outward. The wheel diameter is increased by being pushed out.

そして、ホーニング加工においては、前記のように砥石ホルダに保持した砥石の外周をワークの被加工穴の内周面に接触させて回転させるとともに、その回転軸心の方向に往復移動させるようにしており、その際に、砥石を予め設定した速度で拡径させる方法(以下、定速拡径という)と、ワーク内周面との接触圧が予め接触した値となるようにして拡径させる方法(以下、定圧拡径という)とがある。   In the honing process, the outer periphery of the grindstone held by the grindstone holder as described above is rotated while being brought into contact with the inner peripheral surface of the work hole of the workpiece, and is reciprocated in the direction of the rotation axis. In this case, a method of expanding the diameter of the grindstone at a preset speed (hereinafter referred to as constant speed expansion) and a method of expanding the diameter so that the contact pressure with the inner peripheral surface of the workpiece becomes a pre-contact value. (Hereinafter referred to as constant pressure expansion).

前記定速拡径の場合は、砥石とワークの接触状態に依らず無理矢理拡径する場合があって、ワークの弾性変形が大きくなったり、表面の荒れが大きくなるという不具合があり、一方で定圧拡径の場合は、砥石の自生発刃が十分に行われない条件下では加工が進まない、という問題があるから、両者の得失を考慮し、加工状況に応じて使い分けることが望ましい。   In the case of the constant speed diameter expansion, the diameter may be forcibly expanded regardless of the contact state between the grindstone and the workpiece, and there is a problem that the elastic deformation of the workpiece increases or the surface becomes rough, while the constant pressure is increased. In the case of expanding the diameter, there is a problem that the processing does not proceed under the condition that the self-generated blade of the grindstone is not sufficiently performed. Therefore, it is desirable to use both in accordance with the processing situation in consideration of the advantages and disadvantages of both.

この点つき、例えば特許文献1に記載のホーニング加工方法では、前記定速拡径を行うためのホーニング加工装置をベースにしながら、これにロードセルを付加して、砥石と被加工穴の内周面との接触圧に相当する値を検出し、この検出値をフィードバックしてロッドの押し出し速度、即ち砥石の拡径速度を制御することにより、接触圧を略一定に維持するようにしている。   With this point, for example, in the honing processing method described in Patent Document 1, a honing apparatus for performing constant-speed diameter expansion is used as a base, and a load cell is added to the inner surface of the grindstone and the hole to be processed. A value corresponding to the contact pressure is detected, and the detected value is fed back to control the rod extrusion speed, that is, the diameter expansion speed of the grindstone, thereby maintaining the contact pressure substantially constant.

一例として、加工の初期には略一定の速度で砥石径を拡大させ、その後、接触圧相当値に応じて段階的に速度を落とした上で、加工を終了する直前には暫くの間、前記のように砥石と被加工穴の内周面との接触圧が略一定となるようにすることで、被加工面の仕上がり品質の安定化を図っている。
特開2004−130404号公報
As an example, the diameter of the grindstone is enlarged at a substantially constant speed in the initial stage of processing, and then the speed is decreased stepwise according to the contact pressure equivalent value. As described above, the contact pressure between the grindstone and the inner peripheral surface of the hole to be processed is made substantially constant, so that the finished quality of the surface to be processed is stabilized.
JP 2004-130404 A

しかしながら、前記従来例のように接触圧相当の値を検出し、これをフィードバックして砥石の拡径速度を制御するためには、ロードセルのようなセンサが不可欠である上に、そのような拡径速度の制御の精度を高めようとすれば、モータの作動遅れは勿論、コントローラにおける制御の応答遅れもできるだけ小さくすることが望ましく、システム全体としてかなりコスト高にならざるを得ない。   However, a sensor such as a load cell is indispensable in order to detect a value corresponding to the contact pressure as in the conventional example, and to feed back this value to control the diameter expansion speed of the grindstone. In order to increase the accuracy of control of the radial speed, it is desirable to reduce not only the operation delay of the motor but also the response delay of the control in the controller as much as possible.

しかも、そうして制御精度を高めたとしても、砥石と被加工穴の内周面との接触圧は、微視的には目標とする値の付近で微小な変動を繰り返す(ふらつく)ことになるから、それにより実現できるのは擬似的な定圧拡径に過ぎない。よって、加工終了時における砥石接触圧のバラツキをさらに軽減して、仕上がり品質を高める余地が残されている。   In addition, even if the control accuracy is increased, the contact pressure between the grindstone and the inner peripheral surface of the hole to be processed is microscopically fluctuated (fluctuates) in the vicinity of the target value. Therefore, what can be realized by this is only a pseudo constant pressure expansion. Therefore, there is still room for further reducing the variation in the grindstone contact pressure at the end of processing and improving the finished quality.

本発明は斯かる諸点に鑑みてなされたものであり、その目的とするところは、ホーニングツールにおいて砥石を押し出して拡径させるロッドの構造に工夫を凝らし、装置コストの上昇を抑えながら、定速拡径制御だけでなく、精度の良い定圧拡径制御も行えるようにすることにある。   The present invention has been made in view of such various points, and the object of the present invention is to devise the structure of a rod that extrudes a grindstone in a honing tool and expands the diameter thereof, while suppressing an increase in apparatus cost, while maintaining a constant speed. The purpose is to enable not only the expansion control but also the constant pressure expansion control with high accuracy.

前記の目的を達成するために、この発明では、ホーニングツールのロッドを先端側及び基端側の2つの部材に分割し、その中間に介在させたばね要素を介して軸方向の力を伝える間接状態と、ばね要素を介さない直接状態とに切換えるようにした。   In order to achieve the above object, in the present invention, the rod of the honing tool is divided into two members on the distal end side and the proximal end side, and an indirect state in which axial force is transmitted via a spring element interposed between the members. And a direct state without a spring element.

具体的に、請求項1の発明は、複数の砥石が周方向に並んだホーニングツールの外周をワークの被加工穴の内周面に接触させて回転させるとともに、その回転軸心の方向に往復移動させるようにしたホーニング加工装置が対象である。   Specifically, according to the first aspect of the present invention, the outer periphery of the honing tool in which a plurality of grindstones are arranged in the circumferential direction is rotated while being brought into contact with the inner peripheral surface of the hole to be machined in the workpiece, and reciprocating in the direction of the rotation axis. The honing machine that is moved is the target.

そして、前記ホーニングツールには、前記複数の砥石を各々径方向に進退可能に保持する筒状のホルダと、このホルダ内に挿入したテーパ状の先端部が軸方向に相対移動することで、前記複数の砥石を各々径方向に進退させるロッドと、を備えるとともに、このロッドを、中間にばね要素を挟んで先端側及び基端側の2つの部材に分割し、これら両部材同士が前記ばね要素を介して軸方向の力を伝え合うように接続される間接状態と、当該両部材同士が前記ばね要素を介さず一体的に軸方向に移動するように接続される直接状態と、に切換え可能に構成したものである。   The honing tool includes a cylindrical holder that holds the plurality of grindstones so as to be capable of moving back and forth in the radial direction, and a tapered tip portion inserted into the holder relatively moves in the axial direction. A rod for advancing and retreating each of the plurality of grindstones in the radial direction, and the rod is divided into two members on the distal end side and the proximal end side with a spring element interposed therebetween, and both the members are the spring elements. It is possible to switch between an indirect state in which the forces in the axial direction are communicated via each other and a direct state in which the members are connected so as to move in the axial direction integrally without the spring elements. It is configured.

前記構成のホーニング加工装置では、ホーニングツールのロッドを直接状態とし、その先端側及び基端側の両部材が一体的に軸方向に移動するようにすれば、その移動速度を略一定に制御することで、砥石を押し出し略略一定の速度で拡径させることができる。   In the honing processing apparatus having the above-described configuration, if the rod of the honing tool is in a direct state and both the distal end side and proximal end side members are moved integrally in the axial direction, the moving speed is controlled to be substantially constant. Thus, the grindstone can be pushed out and expanded in diameter at a substantially constant speed.

一方、前記ロッドを間接状態とし、先端側及び基端側の両部材同士がばね要素を介して軸方向の力を伝え合うようにすれば、基端側部材の移動量を制御することによってばね要素の変形量、即ちそのばね力を調整し、先端側部材を介して砥石に加わる拡径力を略一定に維持することができる。   On the other hand, if the rod is in an indirect state and both the distal end side and proximal end side members transmit an axial force via the spring element, the spring is controlled by controlling the movement amount of the proximal end member. By adjusting the deformation amount of the element, that is, its spring force, the diameter expansion force applied to the grindstone via the tip side member can be maintained substantially constant.

斯くして砥石の定速拡径制御と定圧拡径制御とを状況に応じて使い分けることができるとともに、非常に簡単な構造であって、センサや高速アクチュエータ等が不要なことから、コストの大幅な上昇を招くことはない。   Thus, the constant speed expansion control and constant pressure expansion control of the grindstone can be used properly according to the situation, and since it has a very simple structure and does not require a sensor, high-speed actuator, etc., the cost is greatly increased. There will be no significant rise.

尚、前記ロッドの先端側及び基端側部材を繋ぐばね要素としては、例えばコイルスプリングが好適であるが、これに限らず気体ばねを用いてもよいし、さらに液圧シリンダを利用することも可能である。   In addition, as a spring element which connects the front end side and base end side member of the rod, for example, a coil spring is suitable, but not limited thereto, a gas spring may be used, and a hydraulic cylinder may be used. Is possible.

より具体的に、前記ホーニング加工装置には、ロッドの基端側部材を軸方向に移動させる移動機構を備えればよく、その移動機構の制御手段は、ロッドを間接状態から直接状態に切り換えるときには、基端側部材が先端側に移動して先端側部材に当接するように前記移動機構を作動させる一方、ロッドを直接状態から間接状態に切り換えるときには、前記基端側部材が基端側に移動して先端側部材から離れるように前記移動機構を作動させるものとすればよい(請求項2)。こうすれば、従来一般的な定速拡径制御のみを行うためのNC加工装置を利用することができる。   More specifically, the honing apparatus only needs to be provided with a moving mechanism that moves the base end side member of the rod in the axial direction. When the rod is switched from the indirect state to the direct state, When the rod is switched from the direct state to the indirect state, the base end side member moves to the base end side while operating the moving mechanism so that the base end side member moves to the front end side and contacts the front end side member. Then, the moving mechanism may be operated so as to be separated from the distal end side member (Claim 2). If it carries out like this, the NC processing apparatus for performing only the conventional general constant-speed diameter-expansion control can be utilized.

見方を変えれば、本発明は、周方向に並んだ複数の砥石を各々径方向に進退可能に保持する筒状のホルダと、このホルダ内に挿入されたテーパ状の先端部が軸方向に相対移動することで、前記複数の砥石を各々径方向に進退させるロッドと、を備えたホーニングツールであって、前記ロッドを、中間にばね要素を挟んで先端側及び基端側の2つの部材に分割し、この両部材同士が前記ばね要素を介して軸方向の力を伝え合うように接続される間接状態と、当該両部材同士が前記ばね要素を介さず一体的に軸方向に移動するように接続される直接状態と、に切換え可能に構成したものである(請求項3)。   In other words, the present invention relates to a cylindrical holder that holds a plurality of grindstones arranged in the circumferential direction so that each of the grindstones can advance and retract in the radial direction, and a tapered tip portion inserted into the holder is relative to the axial direction. A honing tool comprising a rod for moving the plurality of grindstones in the radial direction by moving, the rod being attached to two members on a distal end side and a proximal end side with a spring element interposed therebetween The indirect state in which the two members are connected so as to transmit the axial force via the spring element, and the two members move in the axial direction integrally without the spring element. It is possible to switch to a direct state connected to the terminal (Claim 3).

このホーニングツールを従来一般的なホーニング加工装置に取り付けるだけで、前記請求項1の発明に係るホーニング加工装置を構成できる。   The honing apparatus according to the first aspect of the present invention can be configured only by attaching the honing tool to a conventional general honing apparatus.

以上、説明したように本発明に係るホーニング加工装置によると、ホーニングツールにおいて砥石径を拡縮させるためのロッドを先端側及び基端側の2つの部材に分割し、その中間に介在させたばね要素を介して軸方向の力を伝え合う間接状態と、ばね要素を介さない直接状態とに切換えるようにしたから、非常に簡単な構造でコストの大幅な上昇を招くことなく、従来一般的なNC加工装置を用いて、それ本来の定速拡径制御及び精度の良い定圧拡径制御を使い分けることができる。   As described above, according to the honing apparatus according to the present invention, the rod for expanding and reducing the grindstone diameter in the honing tool is divided into two members on the distal end side and the proximal end side, and the spring element interposed between them is provided. Since it has been switched between the indirect state in which the axial force is transmitted via the direct state and the direct state not via the spring element, conventional NC processing with a very simple structure without causing a significant increase in cost. By using the apparatus, it is possible to selectively use the original constant speed expansion control and the accurate constant pressure expansion control.

以下、本発明の実施形態を図面に基づいて詳細に説明する。尚、以下の好ましい実施形態の説明は、本質的に例示に過ぎず、本発明、その適用物或いはその用途を制限することを意図するものではない。   Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. It should be noted that the following description of the preferred embodiment is merely illustrative in nature, and is not intended to limit the present invention, its application, or its use.

図1には本発明に係るホーニング加工装置Aの一実施形態を示し、この装置Aは、本体軸1及びその内部に格納されたロッド2からなるホーニングツールBと、そのロッド2を本体軸1に対して軸方向に相対移動(昇降)させる昇降装置3(移動機構)と、この昇降装置3によりロッド2を昇降させて、砥石径を拡縮させる制御装置4と、を備えている。   FIG. 1 shows an embodiment of a honing apparatus A according to the present invention. This apparatus A includes a honing tool B comprising a main body shaft 1 and a rod 2 housed therein, and the rod 2 is connected to the main body shaft 1. And a control device 4 that moves the rod 2 up and down by the lifting device 3 to expand and contract the grindstone diameter.

前記ホーニングツールBにおいて本体軸1は、図2にも示すように、昇降装置3のハウジング30に囲まれる部位の付近を境に上側の部分が中実に形成され、そのハウジング30の上端付近に近接して設けられた鍔部10の直上方の部分が、軸受5を介して支持フレーム6側に回転自在に支持されている。また、本体軸1の上端部は、図示は省略するが、それを高速回転駆動するための回転駆動モータに連結されており、この回転駆動モータ及び前記支持フレーム6は、ホーニング加工の間、本体軸1と一体に上下方向、即ち本体軸1の軸方向に往復動されるようになっている。   In the honing tool B, as shown in FIG. 2, the main body shaft 1 is solidly formed at the upper part of the vicinity of the part surrounded by the housing 30 of the lifting device 3, and close to the vicinity of the upper end of the housing 30. A portion directly above the flange portion 10 provided in this manner is rotatably supported on the support frame 6 side via the bearing 5. Although not shown, the upper end portion of the main body shaft 1 is connected to a rotary drive motor for driving it at high speed, and the rotary drive motor and the support frame 6 are connected to the main body during honing. The shaft 1 is reciprocated integrally with the shaft 1, that is, in the axial direction of the main body shaft 1.

一方、前記本体軸1の下側の部分は下方に開口する円筒状とされていて、その内部の中空部において軸方向(上下方向)に移動可能に前記ロッド2が格納されている。本体軸1の下端には複数の貫通穴1a,1a,…が周方向に並ぶように形成され、その各々に砥石装着部材11,11,…が径方向に進退可能に保持されている(つまり、本体軸1の下端には筒状の砥石ホルダが一体に形成されている)。各砥石装着部材11の外側には一体的に砥石12が固着されており、一方、内側には、下方ほど本体軸1の中心に近付くように傾斜するテーパー面が形成されている。   On the other hand, the lower portion of the main body shaft 1 is formed in a cylindrical shape that opens downward, and the rod 2 is stored in a hollow portion inside the main shaft 1 so as to be movable in the axial direction (vertical direction). A plurality of through holes 1a, 1a,... Are formed at the lower end of the main body shaft 1 so as to be arranged in the circumferential direction, and grindstone mounting members 11, 11,. A cylindrical grindstone holder is integrally formed at the lower end of the main body shaft 1). A grindstone 12 is integrally fixed to the outside of each grindstone mounting member 11, while a tapered surface that is inclined so as to approach the center of the main body shaft 1 is formed on the inside.

それらの砥石装着部材11,11,…に囲まれるようにして、前記ロッド2の下端部(先端部)には、各砥石装着部材11のテーパー面に対応するテーパー状の外周面を有する(即ち先窄まりの)押出部21aが形成されている。この押出部21aが本体軸1に対して相対的に先端側へ移動する(図では降下する)ことにより、砥石装着部材11,11,…が径方向外方に押し出されて、砥石径(周方向に並ぶ砥石12,12,…の外接円の直径)が拡大する。   The lower end portion (tip portion) of the rod 2 has a tapered outer peripheral surface corresponding to the tapered surface of each grindstone mounting member 11 so as to be surrounded by the grindstone mounting members 11, 11,. An extruded portion 21a is formed. The pushing portion 21a moves toward the tip side relative to the main body shaft 1 (lowers in the figure), so that the grindstone mounting members 11, 11,... The diameter of the circumscribed circle of the grindstones 12, 12,.

一方、ロッド2の上端部(基端部)は、前記昇降装置3に連結されて昇降駆動されるようになっている。すなわち、図2に示すように、ロッド2の上端部にはこれを径方向に貫通した状態でピン7が固定されており、このピン7の両端が、本体軸1の中空部の上端付近において周壁を貫通するように形成された軸方向の長孔1bに挿通されて、該本体軸1の外周面から径方向外方に突出している。これらの突出端部は各々、本体軸1の外周を取り巻くように配設された円筒状の保持部材8に固定されている。   On the other hand, the upper end portion (base end portion) of the rod 2 is connected to the elevating device 3 to be driven up and down. That is, as shown in FIG. 2, the pin 7 is fixed to the upper end portion of the rod 2 in a state of passing through the rod 2 in the radial direction, and both ends of the pin 7 are near the upper end of the hollow portion of the body shaft 1. It is inserted into an axially elongated hole 1 b formed so as to penetrate the peripheral wall, and protrudes radially outward from the outer peripheral surface of the main body shaft 1. Each of these projecting end portions is fixed to a cylindrical holding member 8 disposed so as to surround the outer periphery of the main body shaft 1.

この保持部材8は、本体軸1を囲んでその軸方向に移動可能に配設された昇降装置3の円筒状ハウジング30に収容され、その内部に組み込まれた上下一対のスラスト軸受31,31によってハウジング30に対し相対回転するように保持されている。こうしてロッド2の上端部は、昇降装置3のハウジング30に対し回転自在に連結されてこのハウジング30と一体に、本体軸1に対して前記長孔1bの長さ分だけ相対的に昇降(軸方向に移動)可能になっている。   The holding member 8 is housed in a cylindrical housing 30 of an elevating device 3 that surrounds the body shaft 1 and is movably disposed in the axial direction, and is provided by a pair of upper and lower thrust bearings 31, 31 incorporated therein. It is held so as to rotate relative to the housing 30. Thus, the upper end portion of the rod 2 is rotatably connected to the housing 30 of the lifting device 3 and is integrally lifted and lowered relative to the main body shaft 1 by the length of the long hole 1b. Move in the direction).

前記昇降装置3のハウジング30には側方に延びるアーム32が一体形成され、図1に示すように、そのアーム32に固定されたナット33には、上下方向に延びる送りねじ軸34が螺合されている。詳細は図示しないが、送りねじ軸34の上端は、前記支持フレーム6側に固定された砥石径操作モータ35に連結されており、同モータ35によって送りねじ軸34が回転駆動されることで、アーム32と一体にハウジング30さらにはロッド2が昇降駆動されるようになっている。   A laterally extending arm 32 is formed integrally with the housing 30 of the lifting / lowering device 3. As shown in FIG. 1, a feed screw shaft 34 extending vertically is screwed onto a nut 33 fixed to the arm 32. Has been. Although not shown in detail, the upper end of the feed screw shaft 34 is connected to a grindstone diameter operation motor 35 fixed to the support frame 6 side, and the feed screw shaft 34 is rotationally driven by the motor 35. The housing 30 and the rod 2 are driven up and down integrally with the arm 32.

ここで、本発明の特徴部分として前記図2の他、図3にも示すように、この実施形態のロッド2はその上端側の部位において、前記のようにピン7を介して昇降装置3側に連結される基端部材20(基端側部材)と、これに対し軸方向に相対移動可能に組み合わされるロッド本体21(先端側部材)と、に分割されている。   Here, as shown in FIG. 3 in addition to FIG. 2 as a characteristic part of the present invention, the rod 2 of this embodiment is on the lifting device 3 side through the pin 7 as described above at the upper end portion thereof. Are divided into a base end member 20 (base end side member) coupled to the rod body and a rod main body 21 (tip end side member) combined with the base end member 20 so as to be relatively movable in the axial direction.

前記基端部材20は、その上半部が中実に形成され、上述したように昇降装置3側に連結されるピン7が固定されている一方、下半部は下方に開口する円筒状とされていて、その内部(中空部)に前記ロッド本体21の上端部がスライド可能に嵌挿されている。このロッド本体21の上端部には、上下方向に長い長孔21bが径方向に貫通して形成され、ここに挿入されるピン22によって前記基端部材20に連結されるようになっている。   The base end member 20 has a solid upper half and is fixed with the pin 7 connected to the lifting device 3 side as described above, while the lower half has a cylindrical shape that opens downward. And the upper end part of the rod main body 21 is slidably inserted in the inside (hollow part). A long hole 21b elongated in the vertical direction is formed in the upper end portion of the rod body 21 so as to penetrate in the radial direction, and is connected to the base end member 20 by a pin 22 inserted therein.

すなわち、前記基端部材20の下半の円筒状部には、中空部を囲む側壁に互いに径方向に向かい合うように一対の貫通穴20a,20aが形成されており、それらの貫通穴20a,20aに長孔21bが重なるように、ロッド本体21の上端部を基端部材20の下半の中空部内に下方から挿入して、側方からピン22を嵌め入れる。こうするとロッド本体21の上端部は、ピン22によって基端部材20と一体に回転するように連結されるとともに、軸方向については長孔21bの長さ分だけ相対移動可能になる。   That is, a pair of through holes 20a, 20a are formed in the lower half cylindrical portion of the base end member 20 so as to face each other in the radial direction on the side wall surrounding the hollow portion, and these through holes 20a, 20a are formed. The upper end of the rod body 21 is inserted into the lower half of the hollow portion of the base end member 20 from below so that the long hole 21b overlaps, and the pin 22 is fitted from the side. In this way, the upper end portion of the rod body 21 is connected to the base end member 20 so as to rotate integrally with the pin 22 and can be relatively moved in the axial direction by the length of the long hole 21b.

そうして基端部材20の中空部内に嵌挿される部位から下方に所定長さ離れて、ロッド本体21の上側の部分には拡径部21cが形成されており、その直上方に圧縮コイルばね23が巻回されている。このコイルばね23の上端は、基端部材20の下端である円環状端面に当接する一方、コイルばね23の下端は前記拡径部21cの上面に当接しており、ロッド本体21と基端部材20との間にそれらを離遠させる向きのばね力を発生するようになっている。   In this way, a diameter-expanded portion 21c is formed in the upper portion of the rod main body 21 at a predetermined distance from the portion inserted into the hollow portion of the base end member 20, and a compression coil spring is formed immediately above the portion. 23 is wound. The upper end of the coil spring 23 is in contact with the annular end surface which is the lower end of the base end member 20, while the lower end of the coil spring 23 is in contact with the upper surface of the enlarged diameter portion 21c. The spring force of the direction which separates them between 20 is generated.

そのコイルばね23のばね力によってロッド本体21及び基端部材20が互いに離遠する向きに付勢されることから、図2に示すように、基端部材20の中空部の天井面20bと、そこに嵌挿されているロッド本体21の上端面21dとの間には、隙間が形成されることになる。この隙間は、ロッド本体21及び基端部材20の相対移動可能な距離、即ち長孔21bの長さよりも小さく、ロッド本体21及び基端部材20が互いに近接するように相対移動すると、図4に示すように隙間がなくなって、ロッド本体21の上端面21dが基端部材20の中空部の天井面20bに当接するようになる。   Since the rod main body 21 and the base end member 20 are urged away from each other by the spring force of the coil spring 23, as shown in FIG. 2, the ceiling surface 20b of the hollow portion of the base end member 20, A gap is formed between the upper end surface 21d of the rod main body 21 fitted therein. This gap is smaller than the distance that the rod main body 21 and the base end member 20 can move relative to each other, that is, the length of the long hole 21b, and when the rod main body 21 and the base end member 20 are moved relative to each other, FIG. As shown, the gap disappears, and the upper end surface 21 d of the rod body 21 comes into contact with the ceiling surface 20 b of the hollow portion of the base end member 20.

そして、前記図2のようにロッド本体21の上端面21dと基端部材20の中空部の天井面20bとの間に隙間が形成されているときには、両者は直接ではなく、コイルばね23を介して間接的に軸方向の力を伝え合うようになる。一方、図4のようにロッド本体21の上端面21dと基端部材20の中空部の天井面20bとが当接すれば、両者はコイルばね23を介さず、直接に軸方向の力を伝え合うようになり、一体となって先端側に移動するようになる。   When a gap is formed between the upper end surface 21d of the rod body 21 and the ceiling surface 20b of the hollow portion of the base end member 20 as shown in FIG. And indirectly transmit the axial force. On the other hand, if the upper end surface 21d of the rod main body 21 and the ceiling surface 20b of the hollow portion of the base end member 20 come into contact with each other as shown in FIG. As a result, they move as a unit to the tip side.

つまり、この実施形態のロッド2は、中間にコイルばね23を挟んで先端側のロッド本体21と基端部材20とに分割され、それらがコイルばね23を挟んで間接的に接続される間接状態と、コイルばね23を介さず直接に接続される直接状態と、に切換えられるようになっている。尚、いずれの状態においても両者は一体に回転する。   That is, the rod 2 of this embodiment is divided into the rod body 21 and the base end member 20 on the distal end side with the coil spring 23 interposed therebetween, and the indirect state in which they are indirectly connected with the coil spring 23 interposed therebetween. And a direct state in which the coil spring 23 is directly connected without using the coil spring 23. In either state, both rotate together.

そのようなロッド2を昇降させる昇降装置3は、図示省略の加工径検出手段により検出されるワークの被加工穴の加工径等に基づいて、制御装置4により作動される。ここで、加工径検出手段としては、前記本体軸1の下端部に組み込まれたもの(例えば本体軸1の下端部からワーク内周面にエアを噴射してその圧力を検出するもの)でもよいし、当該本体軸1とは別に設置されるものでもよく、従来からホーニング加工等において使用されている周知のものをそのまま使用することができる。   Such a lifting device 3 that lifts and lowers the rod 2 is operated by the control device 4 based on the machining diameter of the workpiece hole detected by a machining diameter detecting means (not shown). Here, the machining diameter detection means may be one incorporated in the lower end portion of the main body shaft 1 (for example, one that detects the pressure by injecting air from the lower end portion of the main body shaft 1 to the inner peripheral surface of the work). However, it may be installed separately from the main body shaft 1, and a well-known one that has been conventionally used in honing or the like can be used as it is.

前記制御装置4による昇降装置3の制御について、より具体的には、ロッド2を昇降させて砥石径を拡縮させる際に、それを前記の間接状態及び直接状態のいずれかに切換えることで、例えば間接状態ではコイルばね23の圧縮変形量を適切に調整して、これに対応する略一定のばね力でもってロッド本体21により砥石を押し出させることが、つまり、砥石と被加工穴の内周面との接触圧が略一定となるようにして、砥石径を拡大させることができる。   About control of the raising / lowering device 3 by the said control apparatus 4, when raising / lowering the diameter of a grindstone by raising / lowering the rod 2, by switching it to either the said indirect state or a direct state, for example, In the indirect state, the amount of compressive deformation of the coil spring 23 is appropriately adjusted, and the grindstone is pushed out by the rod body 21 with a substantially constant spring force corresponding thereto, that is, the inner peripheral surface of the grindstone and the hole to be machined The diameter of the grindstone can be increased so that the contact pressure with the head becomes substantially constant.

また、前記の定圧拡径の状態からさらにロッド2の基端部材20を押し込んで、それがコイルばね23を介さずにロッド本体21に当接して、一体に下降する直接状態とすれば、それらの下降速度に対応する略一定の速度でもって砥石径を拡大させることができる。よって、前記制御装置4は、昇降装置3によってロッド2の基端部材20を軸方向に移動させて、該ロッド2を間接状態及び直接状態のいずれかに切り換える制御手段を構成している。   Further, if the base end member 20 of the rod 2 is further pushed in from the above-described constant pressure expanding state, and it is brought into contact with the rod main body 21 without the coil spring 23 and is in a direct state where it is lowered integrally, The grindstone diameter can be increased at a substantially constant speed corresponding to the descending speed. Therefore, the control device 4 constitutes a control means for moving the proximal end member 20 of the rod 2 in the axial direction by the lifting device 3 and switching the rod 2 between the indirect state and the direct state.

以下に、前記のように切換わるロッド2の状態も含めて、制御装置4による制御動作、即ちホーニング加工装置の作動の一例を具体的に説明する。まず、昇降装置3の砥石径操作モータ35の作動により本体軸1に対しロッド2を引き上げて、砥石径を十分に小さくした状態で、ホーニングツールBの下端部、即ちその本体軸1の下端部をワークの被加工穴の内側に挿入する。この際、ロッド2においては基端部材20がロッド本体21に対して引き上げられることになるから、それらがコイルばね23を介して軸方向の力を伝え合う間接状態になる(図2を参照)。   Hereinafter, an example of the control operation by the control device 4, that is, the operation of the honing device, including the state of the rod 2 that switches as described above, will be described in detail. First, the lower end portion of the honing tool B, that is, the lower end portion of the main body shaft 1 in a state where the rod 2 is pulled up with respect to the main body shaft 1 by the operation of the grindstone diameter operating motor 35 of the lifting device 3 to sufficiently reduce the grindstone diameter. Is inserted inside the workpiece hole. At this time, in the rod 2, the base end member 20 is pulled up with respect to the rod body 21, so that they are in an indirect state in which axial forces are transmitted via the coil spring 23 (see FIG. 2). .

それから回転駆動モータの作動によりホーニングツールB(本体軸1及びロッド2)を高速で回転させるとともに、予め設定された初期拡径速度にて砥石径が拡大するように、前記昇降装置3の作動により本体軸1に対してロッド2を下降させる。すなわち、制御装置4からの信号に応じて砥石径操作モータ35が作動し、送りねじ軸34を回転駆動することで、アーム32、ハウジング30及びロッド2が一体に下降し、そのロッド2の下端の押出部21aが砥石装着部材11,11,…を径方向外方に押し出して、砥石径を拡大させる。   Then, the honing tool B (the main body shaft 1 and the rod 2) is rotated at a high speed by the operation of the rotary drive motor, and the hoisting device 3 is operated so that the grindstone diameter is expanded at a preset initial diameter expansion speed. The rod 2 is lowered with respect to the main body shaft 1. That is, the grindstone diameter operating motor 35 is actuated in response to a signal from the control device 4 to rotationally drive the feed screw shaft 34, whereby the arm 32, the housing 30 and the rod 2 are lowered integrally, and the lower end of the rod 2. ... extrude the grindstone mounting members 11, 11, ... radially outward to increase the grindstone diameter.

そうして拡径された砥石12,12,…の各々がワークの被加工穴の内周面に接触し始めると、それらの接触圧が上昇して、砥石装着部材11,11,…を押し出すロッド本体21には下端の押出部21aから上方への反力が作用する。これによりコイルばね23が圧縮されて、そのばね力によりロッド本体21を下方に押し返すようになるが、さらに基端部材20が下降すると、それは、図4のようにコイルばね23を介さずに、ロッド本体21に接続された直接状態になる。   When each of the expanded grindstones 12, 12,... Starts to contact the inner peripheral surface of the workpiece hole, the contact pressure increases, and the grindstone mounting members 11, 11,. An upward reaction force acts on the rod body 21 from the pushing portion 21a at the lower end. As a result, the coil spring 23 is compressed, and the rod body 21 is pushed back downward by the spring force. However, when the proximal end member 20 is further lowered, it is not via the coil spring 23 as shown in FIG. It becomes a direct state connected to the rod body 21.

この直接状態では、基端部材20がロッド本体21と一体になって下降するようになるから、従来一般的なロッドを用いた場合と同じく、昇降装置3によるロッド2の下降速度に応じて砥石径が拡大するようになる。そこで、予め加工を進めるために設定した略一定の速度で昇降装置3を作動させて、これによりロッド2を略一定の速度で下降させ、これに対応する略一定の速度で砥石径を拡大させる(定速拡径)。   In this direct state, the base end member 20 is lowered integrally with the rod main body 21, so that the grindstone is adjusted according to the lowering speed of the rod 2 by the lifting device 3 as in the case of using a conventional general rod. The diameter becomes larger. Therefore, the lifting / lowering device 3 is operated at a substantially constant speed set in advance for processing, thereby lowering the rod 2 at a substantially constant speed, and increasing the diameter of the grindstone at a substantially constant speed corresponding thereto. (Constant speed expansion).

そうして砥石の定速拡径制御によって加工、即ちワークの被加工穴の内周面の除去が進むことになるが、制御装置4は加工径検出手段により検出される加工径(加工されているワーク内周面の直径)を監視しており、この加工径が予め設定された径に到達した時点で一旦、昇降装置3を停止させて、砥石径の拡大を中断する。続いて、昇降装置3の作動によりロッド2の基端部材20を本体軸1に対して所定量、上昇させると、図2のように、基端部材20の中空部の天井面20bとロッド本体21の上端面21dとが離間して、両者がコイルばね23を介して軸方向の力を伝え合う間接状態になる。   Thus, the processing, that is, the removal of the inner peripheral surface of the hole to be processed of the work proceeds by the constant speed expansion control of the grindstone, but the control device 4 detects the processing diameter (processed by the processing diameter detecting means). The diameter of the inner peripheral surface of the workpiece is monitored, and when the machining diameter reaches a preset diameter, the lifting device 3 is temporarily stopped to stop the increase in the grinding stone diameter. Subsequently, when the base end member 20 of the rod 2 is raised by a predetermined amount with respect to the main body shaft 1 by the operation of the lifting device 3, the ceiling surface 20b of the hollow portion of the base end member 20 and the rod main body as shown in FIG. 21 is separated from the upper end surface 21 d of the member 21, and an indirect state is established in which both transmit axial forces via the coil spring 23.

この間接状態では、コイルばね23の圧縮量に対応するばね力がロッド本体21に下向きに作用し、これに対応する押圧力がロッド本体21の下端の押出部21aから砥石12,12,…に径方向外方に作用することになるから、それら砥石12,12,…とワークの被加工穴の内周面との接触圧を略一定に維持することができ、当該被加工穴の内周面の仕上がり品質を十分に高めることができる。   In this indirect state, a spring force corresponding to the compression amount of the coil spring 23 acts downward on the rod body 21, and a corresponding pressing force is applied to the grindstones 12, 12,... From the pushing portion 21 a at the lower end of the rod body 21. Since it acts on the outside in the radial direction, the contact pressure between the grindstones 12, 12,... And the inner peripheral surface of the hole to be machined can be maintained substantially constant. Surface finish quality can be sufficiently enhanced.

したがって、この実施形態に係るホーニング加工装置Aによると、前記したようにロッド2を直接状態として、その基端部材20及びロッド本体21を一体に下降させるようにすれば、それらの下降速度を昇降装置3により略一定に制御することで、砥石の定速拡径制御を行って、条件によらずホーニング加工を進めることができる。   Therefore, according to the honing apparatus A according to this embodiment, if the rod 2 is in a direct state as described above and the base end member 20 and the rod main body 21 are integrally lowered, the descending speed thereof is increased or decreased. By controlling the device 3 to be substantially constant, the constant speed expansion control of the grindstone can be performed, and the honing process can proceed regardless of the conditions.

一方、ロッド2を間接状態とすれば、基端部材20の下降位置によってコイルばね23の圧縮変形量、即ちそのばね力を適切に調整して、ロッド本体21を介して砥石に加わる拡径力を略一定に維持することができ、砥石との接触状態に応じてワークの被加工穴の内周面が研磨されるようになるから、その仕上がり品質が従来よりも高くなる。   On the other hand, if the rod 2 is in an indirect state, the expansion force applied to the grindstone via the rod body 21 by appropriately adjusting the amount of compressive deformation of the coil spring 23, that is, the spring force, depending on the lowered position of the base end member 20. Can be maintained substantially constant, and the inner peripheral surface of the hole to be processed of the workpiece is polished according to the contact state with the grindstone, so that the finished quality is higher than before.

しかも、砥石と被加工穴の内周面との接触圧相当値を検出するためのセンサや高速アクチュエータ等は不要であり、ロッド2の本体21と基端部材20との間にコイルばね23を介在させるという非常に簡単な構造であるから、装置コストの大幅な上昇を招くこともない。   In addition, a sensor or a high-speed actuator for detecting a contact pressure equivalent value between the grindstone and the inner peripheral surface of the hole to be processed is unnecessary, and a coil spring 23 is provided between the main body 21 of the rod 2 and the base end member 20. Since it is a very simple structure of interposing, the apparatus cost does not increase significantly.

尚、本発明に係るホーニング加工装置の構成は、前記実施形態のものに限定されず、それ以外の種々の構成をも包含する。すなわち、前記実施形態のホーニングツールBでは、ロッド2をその基端側の部位にてロッド本体21と基端部20とに分割しているが、これに限らずロッド2をその軸方向の略中央部或いは先端側の部位にて分割してもよい。   The configuration of the honing apparatus according to the present invention is not limited to that of the above-described embodiment, and includes various other configurations. That is, in the honing tool B of the above-described embodiment, the rod 2 is divided into the rod main body 21 and the base end portion 20 at the base end side portion. You may divide | segment in the center part or the site | part of the front end side.

また、そうして分割した2つの部材の連結方法は前記実施形態のものに限定されず、例えばロッド本体21の基端側に中空部を設けて、そこに基端部材20の先端側を嵌装する等、種々の構造が可能である。また、両部材間に介在させるのはコイルばね23でなくてもよく、例えば気体ばねでもよいし、液圧シリンダを利用することも可能である。   Further, the connecting method of the two members thus divided is not limited to that of the above-described embodiment. For example, a hollow portion is provided on the proximal end side of the rod body 21 and the distal end side of the proximal end member 20 is fitted therein. Various structures are possible, such as wearing. Further, the coil spring 23 may not be interposed between the two members. For example, a gas spring may be used, or a hydraulic cylinder may be used.

さらに、前記の実施形態では、一例としてホーニング加工の初期には砥石を定速拡径させて加工を進め、加工の終了直前に定圧拡径に切換えて仕上げを行うようにしているが、これに限らず、例えば基本的には定圧拡径によって加工し、それが進まない場合に定速拡径に切換える等、種々の加工方法を実行可能である。   Furthermore, in the above embodiment, as an example, at the initial stage of the honing process, the grindstone is diameter-expanded at a constant speed to proceed with the process. For example, it is possible to execute various machining methods such as machining basically by constant pressure expansion, and switching to constant speed expansion when it does not proceed.

以上説明したように、本発明のホーニング加工装置は、簡単な構造でありながら、砥石の定速拡径と定圧拡径とを加工状況に応じて使い分けることができ、有用である。   As described above, the honing apparatus of the present invention is useful because it can use the constant-speed diameter expansion and constant-pressure expansion of the grindstone depending on the machining situation, while having a simple structure.
