Description

この発明は、ホーン或はリーマ等の回転工具を利用して、各種機械装置の部品等に形成する円孔の内径面（内周面）を仕上げる為の孔加工装置の改良に関する。具体的には、上記回転工具を、加工すべき円孔の内側で１往復させる、所謂ワンパスでの精密孔仕上加工を、無人による自動運転で行なえる自動孔加工装置の実現を図るものである。   The present invention relates to an improvement in a hole processing apparatus for finishing an inner diameter surface (inner peripheral surface) of a circular hole formed in a part of various mechanical devices using a rotating tool such as a horn or a reamer. Specifically, an automatic hole drilling device capable of performing the so-called one-pass precision hole finishing by unattended automatic operation, in which the rotary tool is reciprocated once inside the circular hole to be machined, is realized. .

ホーン或はリーマ等の回転工具を利用して、各種機械装置の部品等に形成する円孔の内径面を、所望の寸法及び性状（特に表面粗さ）に仕上げる為の孔加工装置が、従来から各種知られている。又、この様な孔加工装置を使用して円孔の内径面を仕上げる際に、上記回転工具に回転方向或は軸方向寸法の振動を加える事で、この回転工具の目詰まりを防止しつつ、上記内径面の仕上を精密に行なう技術が、特許文献１に記載されている様に、従来から知られている。   2. Description of the Related Art Conventionally, there has been a hole drilling device for finishing inner diameter surfaces of circular holes formed in parts of various mechanical devices to desired dimensions and properties (particularly surface roughness) using a rotating tool such as a horn or a reamer. Various known from. Further, when finishing the inner surface of the circular hole using such a hole machining device, the rotary tool is subjected to vibration in the rotational direction or axial dimension, thereby preventing clogging of the rotary tool. As described in Patent Document 1, a technique for precisely finishing the inner diameter surface has been conventionally known.

上記特許文献１に記載された様な、回転工具の目詰まりを防止しつつ、ワンパスで円孔の内径面の仕上加工を行なう孔加工装置の場合、作業台上に被加工物（ワーク）を出し入れする、ワーク用自動搬送装置を組み込めば、無人運転が可能になる。但し、加工すべき円孔の内径が変わったり、或は、得るべき円孔の内径面の性状が変わった場合には、使用する回転工具を交換しなければならない。これに対して、孔加工装置で回転工具の交換を自動的に（無人で）行なえる実用的な装置は、従来は知られていなかった。この為従来は、複数種類の加工を行なう為には、複数台の孔加工装置を用意する必要があった。この様に複数台の孔加工装置を用意する事は、例えば多品種少量生産の場合に、徒に設備投資が嵩む事に繋がる為、好ましくない。   In the case of a hole processing apparatus that performs the finishing process of the inner diameter surface of the circular hole with one pass while preventing clogging of the rotary tool as described in Patent Document 1, a workpiece (workpiece) is placed on the work table. Unattended operation is possible by incorporating an automatic workpiece transfer device to be taken in and out. However, if the inner diameter of the circular hole to be processed changes or the properties of the inner surface of the circular hole to be obtained change, the rotating tool to be used must be replaced. On the other hand, a practical device capable of automatically (unattended) exchanging the rotary tool with a hole drilling device has not been known. Therefore, conventionally, in order to perform a plurality of types of processing, it is necessary to prepare a plurality of hole processing apparatuses. It is not preferable to prepare a plurality of hole drilling devices in this way because, for example, in the case of multi-product small-volume production, the capital investment increases.

工作機械の工具を自動的に交換する装置として従来から、マシニングセンタ用の工具交換装置が広く知られている。この工具交換装置は、主軸側に設けたテーパ孔と、工具側に設けたテーパコーンとを嵌合させつつ、この工具をこのテーパ孔内に引き込む構造を有するもので、センタープル方式とも呼ばれている。但し、この様なセンタープル方式の工具交換装置は、必ずしも回転工具の中心軸と回転駆動軸（主軸）の中心軸とを厳密に一致させられない可能性がある。そして、これら両中心軸が不一致の状態のまま、上記円孔の内径面の仕上加工を行なうと、この円孔の内径が所望値よりも大きくなる。   2. Description of the Related Art Conventionally, tool changers for machining centers are widely known as devices for automatically changing machine tool tools. This tool changer has a structure in which the tool is pulled into the taper hole while fitting a taper hole provided on the spindle side and a taper cone provided on the tool side, and is also called a center pull system. Yes. However, in such a center-pull type tool changer, there is a possibility that the center axis of the rotary tool and the center axis of the rotary drive shaft (main shaft) cannot be exactly matched. Then, if the inner diameter surface of the circular hole is finished while the two central axes are inconsistent, the inner diameter of the circular hole becomes larger than a desired value.

主軸の中心軸と回転工具の中心軸とを厳密に一致させる為には、この主軸の先端部に、内径を拡縮自在なコレットチャックの如き回転工具把持具を設置し、この回転工具把持具により、上記回転工具の基半部外周面を強く把持する事が好ましい。この様な事情に鑑みて従来から、主軸の先端部にコレットチャックの如き回転工具把持具を設置した孔加工装置は、種々知られている。但し、従来装置の場合には、上記回転工具の交換を行なう為に上記コレットチャック等の回転工具把持具の内径を拡縮する作業は、作業員が人手により行なっていた。この為、前記ワンパスで円孔の内径面の仕上加工を行なう孔加工装置を無人運転する場合には、工具交換を行なう事なく、１種類の内径寸法、且つ、１種類の性状で加工を行なうしかなかった。   In order to make the center axis of the spindle and the center axis of the rotary tool exactly coincide with each other, a rotary tool gripping tool such as a collet chuck whose inner diameter can be expanded and contracted is installed at the tip of the main spindle. It is preferable that the outer peripheral surface of the base half of the rotary tool is strongly gripped. In view of such circumstances, conventionally, various types of drilling apparatuses in which a rotary tool gripping tool such as a collet chuck is installed at the tip of a main shaft are known. However, in the case of the conventional apparatus, the work of expanding and reducing the inner diameter of the rotary tool gripping tool such as the collet chuck in order to replace the rotary tool has been performed manually by an operator. For this reason, when the hole drilling apparatus for finishing the inner surface of the circular hole by one pass is operated unattended, the machining is performed with one type of inner diameter and one type of properties without changing tools. There was only.

特開２００４−２５４１６号公報JP 2004-25416 A

本発明は、上述の様な事情に鑑みて、主軸の先端部にコレットチャックの如き回転工具把持具を設けた構造で、この回転工具把持具の内径の拡縮を自動的に行ない、回転工具の交換を無人で行なえる自動孔加工装置を実現すべく発明したものである。   In view of the circumstances as described above, the present invention has a structure in which a rotary tool gripping tool such as a collet chuck is provided at the tip of the main shaft, and automatically expands and contracts the inner diameter of the rotary tool gripping tool. It was invented to realize an automatic drilling device that can be exchanged unattended.

本発明の自動孔加工装置は、主軸と、主軸頭と、回転工具把持具と、工具用マガジンと、マガジン移動手段とを備える。
上記主軸は、上記主軸頭に回転自在に支持されている。そして、この主軸頭は、この主軸と共にこの主軸の軸方向に移動可能である。
又、上記回転工具把持具は、カム式、或は請求項３に記載した如きコレットチャックで、例えば請求項２に記載した様に、外筒と内筒とを有し、上記主軸の先端部にこの主軸と同心に支持されている。そして、これら外筒と内筒との相対回転に伴う内径の拡縮に基づいて、孔の内径面を加工する為の回転工具を着脱する。
又、上記工具用マガジンは、複数の保持部を備える。そして、これら各保持部に、リーマ或はホーン等の複数の回転工具を、それぞれの中心軸の方向と上記コレットチャックの如き回転工具把持具の中心軸の方向とを一致させた状態で保持する。
又、上記マガジン移動手段は、上記工具用マガジンのうちの何れか１個所の保持部を、上記コレットチャックの如き回転工具把持具に対向する位置に対し進退させる。
そして、このコレットチャックの如き回転工具把持具の内径を拡縮自在とすべく、例えば請求項２に記載した様に、上記内筒を、上記主軸により回転駆動自在としている。
又、上記マガジン移動手段により上記何れか１個所の保持部を上記コレットチャックの如き回転工具把持具に対向する位置に前進させると共に、当該保持部に保持された回転工具の基部がこの回転工具把持具内に挿入させる状態にまで上記主軸頭を上記主軸の軸方向に移動させた状態で、例えば請求項２に記載した様に、上記工具用マガジンに固定の部分と上記回転工具把持具の外筒の一部とを係合させて、この外筒の回転を阻止する様に構成している。 The automatic hole drilling apparatus of the present invention includes a spindle, a spindle head, a rotary tool gripper, a tool magazine, and a magazine moving means.
The main shaft is rotatably supported by the main shaft head. And this spindle head is movable in the axial direction of this spindle together with this spindle.
Further, the rotary tool gripping tool is a cam type or a collet chuck as described in claim 3. For example, as described in claim 2, the rotary tool gripper has an outer cylinder and an inner cylinder, and a tip end portion of the main shaft. Is supported concentrically with the main shaft. And based on the expansion / contraction of the internal diameter accompanying relative rotation with these outer cylinders and inner cylinders, the rotary tool for processing the internal-diameter surface of a hole is attached or detached.
The tool magazine includes a plurality of holding portions. A plurality of rotary tools such as reamers or horns are held in these holding portions in a state in which the direction of each central axis and the direction of the central axis of a rotary tool gripper such as the collet chuck are matched. .
The magazine moving means advances or retracts a holding portion at any one of the tool magazines to a position facing a rotary tool gripping tool such as the collet chuck.
In order to make the inner diameter of the rotary tool gripper such as the collet chuck expandable and contractible, for example, as described in claim 2, the inner cylinder is rotatably driven by the main shaft.
Further, the magazine moving means advances any one of the holding portions to a position facing a rotary tool gripping tool such as the collet chuck, and the base of the rotary tool held by the holding portion holds the rotary tool gripping. In a state where the spindle head is moved in the axial direction of the spindle until it is inserted into the tool, for example, as described in claim 2, a portion fixed to the tool magazine and an outer portion of the rotary tool gripper are removed. A part of the cylinder is engaged to prevent the rotation of the outer cylinder.

上述の様に構成する本発明の自動孔加工装置の場合には、作業員の人手による事なくコレットチャックの如き回転工具把持具の内径の拡縮、並びに、この回転工具把持具の内径側への回転工具の基部の抜き差しを行なえる。
先ず、上記コレットチャックの如き回転工具把持具の内径の拡縮は、例えば請求項２に記載した発明の場合には、主軸頭を主軸の軸方向に移動させ工具用マガジンに固定の部分とこの回転工具把持具の外筒の一部とを係合させた状態で、上記主軸を回転させる事により行なえる。この状態では、上記外筒が回転する事はないので、この主軸の回転に伴って上記回転工具把持具の内筒が回転すると、この内筒と上記外筒との相対回転に伴って、この回転工具把持具の内径が拡縮する。この内径を拡大するか収縮させるかは、上記主軸を何れの方向に回転させるかにより決定される。
又、上記回転工具把持具の内径側への回転工具の基部の抜き差しは、マガジン移動手段により何れか１個所の保持部を上記回転工具把持具に対向する位置に前進させた状態で、上記主軸頭を上記主軸の軸方向に移動させる事により行なえる。
そして、上記回転工具把持具の内径の拡縮と、この回転工具把持具の内径側への回転工具の基部の抜き差しとを、互いに関連付けて（前後して）行なえば、上記主軸の先端部への上記回転工具の着脱を、作業員の人手によらず、自動的に行なえる。 In the case of the automatic drilling device of the present invention configured as described above, the inner diameter of the rotary tool gripping tool is expanded and contracted and the inner diameter side of the rotary tool gripping tool such as a collet chuck is increased without manual labor of the operator. The base of the rotary tool can be inserted and removed.
First, the expansion / contraction of the inner diameter of the rotary tool gripper such as the collet chuck is, for example, in the case of the invention described in claim 2, the spindle head is moved in the axial direction of the spindle and the portion fixed to the tool magazine is rotated. This can be done by rotating the main shaft while engaging a part of the outer cylinder of the tool gripper. In this state, since the outer cylinder does not rotate, when the inner cylinder of the rotary tool gripper rotates with the rotation of the main shaft, the outer cylinder rotates with the relative rotation between the inner cylinder and the outer cylinder. The inner diameter of the rotary tool gripper expands and contracts. Whether the inner diameter is expanded or contracted is determined depending on in which direction the main shaft is rotated.
In addition, when the base of the rotary tool is inserted into and removed from the inner diameter side of the rotary tool gripping tool, the spindle is moved in a state in which any one holding portion is advanced to a position facing the rotary tool gripping tool by the magazine moving means. This can be done by moving the head in the axial direction of the main axis.
Then, if the expansion / contraction of the inner diameter of the rotary tool gripping tool and the insertion / removal of the base of the rotary tool to the inner diameter side of the rotary tool gripping tool are performed in association with each other (before and after), The rotating tool can be attached and detached automatically without the need for manual labor.

本発明を実施する場合に好ましくは、請求項５に記載した様に、主軸を、その中心軸を鉛直方向に配置した状態で、フレームに対し昇降可能に設置された主軸頭に回転自在に支持する。又、工具用マガジンは、それぞれが保持部であって外周縁側に開口した複数の保持切り欠きを有する円盤状とし、鉛直方向に配置された回転軸に固定する。そして、各回転工具はこれら各保持切り欠きに、下方に落下する事はないが上記工具用マガジンの径方向外方に変位する事で抜き取り可能に保持する。更に、マガジン移動手段は、上記回転軸の中心と、コレットチャックの如き回転工具把持具との間で回転工具の受渡を行なわせるべき保持切り欠きの中心とを結ぶ直線方向に水平移動する構造とする。   Preferably, when carrying out the present invention, preferably, as described in claim 5, the main shaft is rotatably supported on a main shaft head that can be moved up and down with respect to the frame in a state where its central axis is arranged in the vertical direction. To do. The tool magazine has a disk shape having a plurality of holding cutouts each of which is a holding portion and opened on the outer peripheral edge side, and is fixed to a rotating shaft arranged in the vertical direction. Each rotary tool does not fall downward in each of the holding cutouts, but is held so as to be detachable by being displaced radially outward of the tool magazine. Further, the magazine moving means is configured to horizontally move in a linear direction connecting the center of the rotating shaft and the center of the holding notch to which the rotating tool should be delivered between the rotating tool gripping tool such as a collet chuck. To do.

又、上述の様な請求項５に記載した発明を実施する場合に、更に好ましくは、請求項６に記載した様に、上記工具用マガジンの上面で各保持切り欠きの近傍部分に係止突部を、それぞれ上方に突出する状態で形成する。又、外筒の下端部外周面に係止凹部を、この外筒の下面に開口する状態で形成する。そして、マガジン移動手段により何れか１個所の保持部（保持切り欠き）を上記コレットチャックの如き回転工具把持具に対向する位置に前進させると共に、当該保持部に保持された回転工具の基部がこの回転工具把持具内に挿入させる状態にまで上記主軸頭を下降させた状態で、上記係止突部と上記係止凹部とを係合させる。そして、この係合により、上記主軸の回転に伴う内筒の回転に基づく上記回転工具把持具の拡縮時に、上記外筒の回転を阻止する。   Further, when the invention described in claim 5 as described above is carried out, more preferably, as described in claim 6, a locking protrusion is formed in the vicinity of each holding notch on the upper surface of the tool magazine. The parts are formed so as to protrude upward. Further, a locking recess is formed on the outer peripheral surface of the lower end portion of the outer cylinder so as to open to the lower surface of the outer cylinder. Then, the magazine moving means advances any one holding portion (holding notch) to a position facing the rotary tool gripping tool such as the collet chuck, and the base of the rotary tool held by the holding portion is The locking projection and the locking recess are engaged with the spindle head lowered to a state of being inserted into the rotary tool gripper. And by this engagement, the rotation of the outer cylinder is prevented at the time of expansion / contraction of the rotary tool gripper based on the rotation of the inner cylinder accompanying the rotation of the main shaft.

尚、上記回転工具把持具としてコレットチャックを使用する場合にその内筒は、上記主軸と別体のものをこの主軸の先端部に結合固定する事もできるが、請求項４に記載した様に、この主軸の先端部を中空に加工する事により、上記内筒をこの主軸の先端部に一体に設ける事もできる。この様に構成すれば、上記コレットチャック設置部分の小型・軽量化が可能になる他、このコレットチャックの中心軸と上記主軸の中心軸とを厳密に一致させる為の調整作業も容易になる。   In the case where a collet chuck is used as the rotary tool gripper, the inner cylinder can be fixedly coupled to the tip of the main shaft separately from the main shaft, as described in claim 4. The inner cylinder can also be provided integrally with the tip of the main shaft by processing the tip of the main shaft into a hollow shape. With this configuration, the collet chuck installation portion can be reduced in size and weight, and adjustment work for precisely matching the center axis of the collet chuck and the center axis of the main shaft can be facilitated.

図１〜５は、本発明の実施例を示している。本発明の自動孔加工装置は、主軸１と、主軸頭２と、回転工具把持具であるコレットチャック３と、工具用マガジン４と、マガジン移動手段５とを備える。
上記主軸１は、その中心軸を鉛直方向に配置した状態で、上記主軸頭２に、回転自在に支持されている。そして、この主軸頭２は、図示しないフレームに対し、鉛直方向の移動（昇降）自在に支持している。この鉛直方向の移動量は、図示しないＮＣ制御器により制御される。 1 to 5 show an embodiment of the present invention. The automatic hole drilling apparatus of the present invention includes a spindle 1, a spindle head 2, a collet chuck 3 as a rotary tool gripper, a tool magazine 4, and a magazine moving means 5.
The main shaft 1 is rotatably supported by the main shaft head 2 with its central axis arranged in the vertical direction. The spindle head 2 is supported so as to be movable (moved up and down) in the vertical direction with respect to a frame (not shown). The amount of movement in the vertical direction is controlled by an NC controller (not shown).

又、上記コレットチャック３は、図４に詳示する様に、上記主軸１の先端部にこの主軸１と同心に支持されたもので、外筒６と内筒７とを有する。そして、これら外筒６と内筒７との相対回転に伴う内径の拡縮に基づいて、図示しない被加工物に形成した円孔の内径面を加工する為の、回転工具８を着脱する。この様なコレットチャック３自体は、市販のものを使用し、その構造及び作用は従来から広く知られているが、本発明を実施する場合に重要な部品である為、以下に説明する。尚、本実施例の場合には、上記主軸１の先端部を中空に加工（中心部に、下端開口部に向けて内径が大きくなる方向に傾斜したテーパ孔を形成）する事により、上記コレットチャック３の内筒７をこの主軸１の先端部に一体に設けている。従って、この内筒７は、この主軸１により、所望の方向に回転駆動自在である。   Further, as shown in detail in FIG. 4, the collet chuck 3 is supported at the tip of the main shaft 1 concentrically with the main shaft 1 and has an outer cylinder 6 and an inner cylinder 7. And based on the expansion / contraction of the internal diameter accompanying the relative rotation of these outer cylinder 6 and inner cylinder 7, the rotary tool 8 for processing the internal diameter surface of the circular hole formed in the to-be-processed object is removed. As such a collet chuck 3 itself, a commercially available one is used, and the structure and operation thereof have been widely known. However, since these are important parts for carrying out the present invention, they will be described below. In the case of the present embodiment, the collet is formed by processing the tip end portion of the main shaft 1 into a hollow shape (a taper hole inclined in the direction in which the inner diameter increases toward the lower end opening portion in the center portion). An inner cylinder 7 of the chuck 3 is integrally provided at the tip of the main shaft 1. Therefore, the inner cylinder 7 can be driven to rotate in a desired direction by the main shaft 1.

上記内筒７の内側には、円周方向に複数に（例えば３〜４個に）分割された把持片を円筒状に組み合わせて成る、把持筒９を内嵌している。この把持筒９の中間部乃至上端部外周面は、上端に向かう程外径が小さくなる方向に傾斜した円すい状凸面とし、この部分の外周面を、上記内筒７の（テーパ孔の）内周面に当接させている。従って、上記把持筒９の内径は、上記主軸１に対してこの把持筒９を上方に変位させる程小さくなり、逆に、この把持筒９を下方に位置させる程大きくなる。   Inside the inner cylinder 7, a gripping cylinder 9 formed by combining gripping pieces divided into a plurality of pieces (for example, 3 to 4 pieces) in the circumferential direction in a cylindrical shape is fitted. The outer peripheral surface of the middle or upper end of the gripping cylinder 9 is a conical convex surface inclined in a direction in which the outer diameter decreases toward the upper end, and the outer peripheral surface of this part is the inner (in the tapered hole) of the inner cylinder 7. It is in contact with the peripheral surface. Accordingly, the inner diameter of the gripping cylinder 9 decreases as the gripping cylinder 9 is displaced upward with respect to the main shaft 1 and conversely increases as the gripping cylinder 9 is positioned downward.

又、上記内筒７の下部外周面に形成した雄ねじ部１０に、上記外筒６の中間部内周面にキー係合により支持したスリーブ１１の内周面に形成した雌ねじ部１２を螺合させている。従って、この外筒６は上記内筒７に対し、回転しつつ昇降する状態に組み付けられている。又、上記スリーブ１１の下端部にこのスリーブ１１に対する回転自在に支持した、押圧環１３の内周面と、上記把持筒９の下端部外周面とを当接させている。これら両周面はそれぞれ、それぞれ下方に向かう程直径が小さくなる方向に傾斜している。   Further, a female screw portion 12 formed on the inner peripheral surface of the sleeve 11 supported by key engagement with the inner peripheral surface of the intermediate portion of the outer cylinder 6 is screwed to the male screw portion 10 formed on the lower outer peripheral surface of the inner cylinder 7. ing. Therefore, the outer cylinder 6 is assembled to the inner cylinder 7 so as to move up and down while rotating. Further, the inner peripheral surface of the press ring 13 and the outer peripheral surface of the lower end portion of the gripping cylinder 9 that are rotatably supported with respect to the sleeve 11 are brought into contact with the lower end portion of the sleeve 11. Each of these peripheral surfaces is inclined in a direction in which the diameter decreases as it goes downward.

又、上記外筒６の下端部中心で上記把持筒９の直下位置には、上記回転工具８の基部１４をこの把持筒９に挿入する為の挿通孔１５を形成し、この挿通孔１５の内周面に、異物進入防止の為のシールリング１６を係止している。更に、上記外筒６の下端部外周面の円周方向等間隔複数個所（例えば４〜８個所）に係止凹部１７、１７を、それぞれこの外筒６の下面に開口する状態で形成している。   Further, an insertion hole 15 for inserting the base portion 14 of the rotary tool 8 into the gripping cylinder 9 is formed at the center of the lower end portion of the outer cylinder 6 and immediately below the gripping cylinder 9. A seal ring 16 for preventing foreign matter entry is locked to the inner peripheral surface. Furthermore, locking recesses 17 and 17 are formed at a plurality of circumferentially equidistantly spaced locations (for example, 4 to 8 locations) on the outer peripheral surface of the lower end portion of the outer cylinder 6 so as to open to the lower surface of the outer cylinder 6. Yes.

又、前記工具用マガジン４は、図１、３に示す様に円盤状で、それぞれが保持部であって外周縁側に開口した、複数の略Ｕ字形の保持切り欠き１８、１８を、円周方向等間隔位置に有する。この様な工具用マガジン４は、鉛直方向に配置された回転軸１９の上端部に固定されており、電動モータ２０により、歯車減速機２１を介して所望方向に所望角度だけ回転駆動される。この様にして行なう、上記工具用マガジン４の回転角度も、ＮＣ制御器により制御される。   Further, the tool magazine 4 has a disk shape as shown in FIGS. 1 and 3, each of which has a plurality of substantially U-shaped holding notches 18, 18 which are holding portions and open to the outer peripheral edge side. It is in the direction equidistant position. Such a tool magazine 4 is fixed to the upper end portion of the rotary shaft 19 arranged in the vertical direction, and is rotated by a desired angle in a desired direction via a gear reducer 21 by an electric motor 20. The rotation angle of the tool magazine 4 performed in this way is also controlled by the NC controller.

上記工具用マガジン４に保持される各回転工具８、８は、それぞれの中間部に、その上下に隣接する部分よりも外径が小さくなった括れ部を設けている。上記各保持切り欠き１８、１８の幅寸法は、この括れ部の外径よりは少し大きいが、この括れ部の上下に隣接する部分の外径よりは小さい。従って上記各回転工具８、８は、それぞれの括れ部を上記各保持切り欠き１８、１８に、上記工具用マガジン４の外周縁側開口から挿入する事により、この工具用マガジン４に保持される。この状態で上記各回転工具８、８はこの工具用マガジン４に、下方に落下する事はないが、この工具用マガジン４の径方向外方に変位する事で抜き取り可能に保持される。   Each of the rotary tools 8 and 8 held by the tool magazine 4 is provided with a constricted portion whose outer diameter is smaller than that of adjacent portions in the middle portion thereof. The width dimension of each of the holding notches 18 and 18 is slightly larger than the outer diameter of the constricted portion, but is smaller than the outer diameter of the portion adjacent to the constricted portion. Accordingly, the rotary tools 8 and 8 are held in the tool magazine 4 by inserting the constricted portions into the holding notches 18 and 18 from the outer peripheral side opening of the tool magazine 4. In this state, the rotary tools 8 and 8 do not fall down on the tool magazine 4 but are held in a detachable manner by being displaced radially outward of the tool magazine 4.

尚、図示の例では、上記各回転工具８、８が上記各保持切り欠き１８、１８から不用意抜け出て脱落する事を防止する為に、これら各保持切り欠き１８、１８部分に、図５に示す様な脱落防止腕２２、２２を設置している。これら脱落防止腕２２、２２は、それぞれの先端部にローラ２３、２３を枢支すると共に、引っ張りばね２４により、互いに近づく方向の弾力を付与している。この様な脱落防止腕２２、２２は、上記各保持切り欠き１８、１８内に挿入された、上記各回転工具８、８の括れ部を抑えて、この括れ部が不用意にこれら各保持切り欠き１８、１８の開口側に移動する事を防止する。但し、後述するマガジン移動手段５により上記工具用マガジン４を移動させる際には、上記引っ張りばね２４の弾力に抗して変位し、上記括れ部が上記各保持切り欠き１８、１８に出入りする事を許容する。   In the illustrated example, in order to prevent the rotary tools 8 and 8 from being inadvertently pulled out from the holding notches 18 and 18 and falling off, the respective holding notches 18 and 18 are shown in FIG. The fall prevention arms 22 and 22 as shown in FIG. The drop-off prevention arms 22 and 22 pivotally support the rollers 23 and 23 at their respective distal ends, and are given elasticity in a direction approaching each other by a tension spring 24. Such drop-off prevention arms 22 and 22 suppress the constricted portions of the rotary tools 8 and 8 inserted into the respective holding notches 18 and 18 so that the constricted portions are inadvertently arranged. The movement to the opening side of the notches 18 and 18 is prevented. However, when the tool magazine 4 is moved by the magazine moving means 5 to be described later, the tool magazine 4 is displaced against the elasticity of the tension spring 24 and the constricted portion enters and exits the holding cutouts 18 and 18. Is acceptable.

又、上記工具用マガジン４の上面の円周方向等間隔複数個所で、上記各保持切り欠き１８、１８の径方向内側に隣接する部分に係止突部２５、２５を、それぞれ上方に突出する状態で形成している。これら係止突部２５、２５の形成位置及び大きさは、前記コレットチャック３の外筒６の下端部外周面に形成した、前記各係止凹部１７、１７の何れかと係合自在な位置及び大きさとしている。即ち、次述するマガジン移動手段５により上記各保持切り欠き１８、１８のうちの何れか１個所の保持切り欠き１８を、前記コレットチャック３の直下位置に進入させると共に、当該保持切り欠き１８に保持された前記回転工具８の基部１４が上記コレットチャック３の把持筒９内に挿入させる状態にまで前記主軸頭２を下降させた状態で、上記１個所の保持切り欠き１８に隣接した係止突部２５と上記何れかの係止凹部１７とが係合する様にしている。これら係止突部２５と係止凹部１７とが係合した状態では、この係止凹部１７を形成した上記外筒６の回転が阻止される。   Further, locking projections 25, 25 protrude upward at portions of the upper surface of the tool magazine 4 that are adjacent to each other on the radially inner side of the holding notches 18, 18 at a plurality of circumferentially equidistant positions. It is formed in a state. The positions and sizes of the locking projections 25, 25 are such that the locking protrusions 25, 25 can be engaged with any of the locking recesses 17, 17 formed on the outer peripheral surface of the lower end of the outer cylinder 6 of the collet chuck 3. The size. That is, the magazine moving means 5 described below causes one of the holding cutouts 18, 18 to enter the position immediately below the collet chuck 3, and to the holding cutout 18. In the state where the spindle head 2 is lowered to the state where the base 14 of the held rotary tool 8 is inserted into the gripping cylinder 9 of the collet chuck 3, the lock adjacent to the one holding notch 18. The protrusion 25 and any one of the locking recesses 17 are engaged with each other. In a state where the locking projections 25 and the locking recesses 17 are engaged, the rotation of the outer cylinder 6 in which the locking recesses 17 are formed is prevented.

更に、上記マガジン移動手段５は、上記工具用マガジン４のうちの何れか１個所の保持切り欠き１８を、上記コレットチャック３の直下位置に対し進退させる。この為に本実施例の場合には、上記コレットチャック３と、前記回転軸１９と、前記電動モータ２０と、前記歯車減速機２１とを、移動フレーム２６に設置している。又、工場の床面上に水平方向に設置した固定フレーム２７の上面に、ガイドレール２８、２８を配設している。そして、これら両ガイドレール２８、２８上に上記移動フレーム２６を載せて、この移動フレーム２６を水平移動自在としている。この移動フレーム２６が、図１の右端まで前進し切った状態で、上記何れか１個所の保持切り欠き１８に保持された回転工具８の中心軸と、上記コレットチャック３の中心軸とが一致する様に、各部の設置位置及び設置方向を規制している。図示の例では、上記移動フレーム２６は、前記回転軸１９の中心と、上記コレットチャック３との間で上記回転工具８の受渡を行なわせるべき、上記何れか１個所の保持切り欠き１８の中心とを結ぶ直線（図３の鎖線α）方向に水平移動する。尚、上記移動フレーム２６が図１の左方に退避し切った状態では、前記主軸１の下方には、この移動フレーム２６に代えて、被加工物を設置した、図示しないワーク支持台が進入する。   Further, the magazine moving means 5 moves the holding notch 18 at any one of the tool magazines 4 forward and backward with respect to the position immediately below the collet chuck 3. Therefore, in the case of the present embodiment, the collet chuck 3, the rotating shaft 19, the electric motor 20, and the gear reducer 21 are installed on the moving frame 26. Further, guide rails 28 and 28 are disposed on the upper surface of a fixed frame 27 installed in a horizontal direction on the floor of the factory. The moving frame 26 is placed on the guide rails 28 and 28 so that the moving frame 26 can be moved horizontally. With the moving frame 26 fully advanced to the right end in FIG. 1, the central axis of the rotary tool 8 held in any one of the holding notches 18 matches the central axis of the collet chuck 3. Thus, the installation position and installation direction of each part are regulated. In the illustrated example, the moving frame 26 is the center of the holding notch 18 at any one of the positions where the rotary tool 8 should be delivered between the center of the rotating shaft 19 and the collet chuck 3. And move horizontally in the direction of the straight line (dotted line α in FIG. 3). In the state where the moving frame 26 is fully retracted to the left in FIG. 1, a workpiece support base (not shown) in which a workpiece is placed instead of the moving frame 26 enters below the main shaft 1. To do.

上述の様に構成する本実施例の自動孔加工装置は、次の様に動作する事で、作業員の人手による事なく、上記コレットチャック３を構成する前記把持筒９の内径の拡縮、並びに、この把持筒９の内径側への上記回転工具８の基部１４の抜き差しを行なえる。尚、この抜き差し作業は、上記移動フレーム２６が図１の右端まで前進し、上記何れか１個所の保持切り欠き１８に保持された回転工具８の中心軸と、上記コレットチャック３の中心軸とが一致した状態で行なう。   The automatic hole drilling apparatus of the present embodiment configured as described above operates as follows, so that the inner diameter of the gripping cylinder 9 constituting the collet chuck 3 can be expanded and contracted without any manual operation by an operator. The base 14 of the rotary tool 8 can be inserted into and removed from the inner diameter side of the gripping cylinder 9. In this insertion / removal operation, the moving frame 26 moves forward to the right end in FIG. 1 and the central axis of the rotary tool 8 held in any one of the holding notches 18 and the central axis of the collet chuck 3 This is done in a state where the two match.

先ず、上記コレットチャック３の把持筒９の内径の拡縮を行なう際には、前記主軸頭２を下降させる。そして、前記工具用マガジン４の上面に設けた前記各係止突部２５、２５のうちで、上記何れか１個所の保持切り欠き１８に隣接する係止突部２５と、上記コレットチャック３の外筒６の下端部外周面に形成した前記各係止凹部１７、１７のうちの何れかの係止凹部１７とを係合させる。これら係止突部２５と係止凹部１７とを係合させる際には、ＮＣ制御器により、前記主軸１及び上記工具用マガジン４の回転方向の位相を規制する。この様にして、上記係止突部２５と係止凹部１７とを係合させたならば、上記主軸１を所望方向に回転させる。これら係止突部２５と係止凹部１７とを係合させた状態では、上記外筒６が回転する事はないので、上記主軸１の回転に伴って上記コレットチャック３の内筒７が回転する。この結果、この内筒７と上記外筒６との相対回転に伴って、前記スリーブ１１がこの内筒７（主軸１）に対して昇降し、上記コレットチャック３を構成する前記把持筒９の内径が拡縮する。この内径を拡大するか収縮させるかは、上記主軸１を何れの方向に回転させるかにより決定される。   First, when the inner diameter of the gripping cylinder 9 of the collet chuck 3 is enlarged or reduced, the spindle head 2 is lowered. Of the locking protrusions 25, 25 provided on the upper surface of the tool magazine 4, the locking protrusion 25 adjacent to any one of the holding notches 18 and the collet chuck 3. One of the locking recesses 17, 17 formed on the outer peripheral surface of the lower end portion of the outer cylinder 6 is engaged with the locking recess 17. When the locking protrusions 25 and the locking recesses 17 are engaged, the NC controller regulates the phase in the rotational direction of the main shaft 1 and the tool magazine 4. When the locking projection 25 and the locking recess 17 are engaged in this manner, the main shaft 1 is rotated in a desired direction. Since the outer cylinder 6 does not rotate in a state where the locking protrusions 25 and the locking recesses 17 are engaged, the inner cylinder 7 of the collet chuck 3 rotates as the main shaft 1 rotates. To do. As a result, with the relative rotation between the inner cylinder 7 and the outer cylinder 6, the sleeve 11 moves up and down with respect to the inner cylinder 7 (main shaft 1), and the grip cylinder 9 constituting the collet chuck 3 is moved. The inner diameter expands and contracts. Whether the inner diameter is expanded or contracted is determined depending on in which direction the main shaft 1 is rotated.

又、上記コレットチャック３の把持筒９の内径側への上記回転工具８の基部１４の抜き差しは、上記何れか１個所の保持切り欠き１８を上記コレットチャック３の直下位置に前進させた状態で、上記主軸頭２を昇降させる事により行なえる。即ち、上記把持筒９の内径を拡げた状態で、この主軸頭２を下降させれば、上記回転工具８の基部１４を上記把持筒９内に差し込める。これに対して、上記把持筒９の内径を拡げた状態で、この主軸頭２を上昇させれば、上記回転工具８の基部１４を上記把持筒９から抜き取れる。   In addition, the base 14 of the rotary tool 8 is inserted into and removed from the inner diameter side of the gripping cylinder 9 of the collet chuck 3 in a state in which any one of the holding notches 18 is advanced to a position directly below the collet chuck 3. This can be done by raising and lowering the spindle head 2. That is, if the spindle head 2 is lowered while the inner diameter of the gripping cylinder 9 is expanded, the base 14 of the rotary tool 8 can be inserted into the gripping cylinder 9. On the other hand, if the spindle head 2 is raised with the inner diameter of the gripping cylinder 9 expanded, the base portion 14 of the rotary tool 8 can be extracted from the gripping cylinder 9.

そして、上記コレットチャック３の把持筒９の内径の拡縮と、この把持筒９の内径側への上記回転工具８の基部１４の抜き差しとを、互いに関連付けて（前後して）行なえば、上記主軸１の先端部への上記回転工具８の着脱を、作業員の人手によらず、自動的に行なえる。工具交換を行なう際には、先ず、前記移動フレーム２６を図１の左端まで後退させた状態で、上記主軸頭２を下降させる。次いで、この移動フレーム２６を図１の右端まで前進させ、上記コレットチャック３の把持筒９に把持された、それまで使用していた回転工具８の括れ部を、前記工具用マガジン４の、それまで空であった保持切り欠き１８に進入させる。   If the expansion / contraction of the inner diameter of the gripping cylinder 9 of the collet chuck 3 and the insertion / removal of the base 14 of the rotary tool 8 to / from the inner diameter side of the gripping cylinder 9 are performed in association with each other (back and forth), the spindle The rotary tool 8 can be automatically attached to and detached from the front end portion of 1 without depending on the hand of the operator. When performing the tool change, first, the spindle head 2 is lowered with the moving frame 26 retracted to the left end in FIG. Next, the moving frame 26 is advanced to the right end in FIG. 1, and the constricted portion of the rotary tool 8 used so far, which is gripped by the gripping cylinder 9 of the collet chuck 3, is The holding notch 18 that has been empty until is entered.

次いで、上記把持筒９の内径を拡張してから、上記主軸頭２を上昇させ、上記それまで使用していた回転工具８の基部１４を、上記把持筒９から抜き出す。次いで、前記工具用マガジン４を所定角度回転させて、新たに使用する回転工具８を上記コレットチャック３の直下位置に移動させる。そして、上記把持筒９の内径を拡げた状態のまま、上記主軸頭２を下降させ、上記新たに使用する回転工具８の基部１４を上記把持筒９内に進入させる。次いで、上記主軸１を回転させてこの把持筒９の内径を縮め、この把持筒９の内側に上記新たに使用する回転工具８の基部１４を固定する。そして、最後に、上記移動フレーム２６を図１の左端位置にまで後退させて、上記新たに使用する回転工具８を上記工具用マガジン４の保持切り欠き１８から抜き取る。   Next, after expanding the inner diameter of the gripping cylinder 9, the spindle head 2 is raised, and the base portion 14 of the rotary tool 8 used so far is extracted from the gripping cylinder 9. Next, the tool magazine 4 is rotated by a predetermined angle, and the rotary tool 8 to be newly used is moved to a position directly below the collet chuck 3. Then, while the inner diameter of the gripping cylinder 9 is expanded, the spindle head 2 is lowered, and the base 14 of the rotary tool 8 to be newly used enters the gripping cylinder 9. Next, the main shaft 1 is rotated to reduce the inner diameter of the gripping cylinder 9, and the base 14 of the newly used rotary tool 8 is fixed inside the gripping cylinder 9. Finally, the moving frame 26 is retracted to the left end position in FIG. 1 and the newly used rotary tool 8 is extracted from the holding notch 18 of the tool magazine 4.

尚、図示の例では、内径の拡縮に基づいて回転工具を着脱する回転工具把持具としてコレットチャックを使用した場合に就いて説明したが、この回転工具把持具は、主軸の回転を利用して、人手によらずに内径を拡縮できるものであれば、カム式のもの等、他の構造のものを使用できる。   In the illustrated example, the case where the collet chuck is used as a rotary tool gripping tool for attaching and detaching the rotary tool based on the expansion / contraction of the inner diameter has been described. However, this rotary tool gripping tool uses the rotation of the spindle. As long as the inner diameter can be enlarged / reduced without manual intervention, a cam-type one can be used.
