Description

本発明は、対象物に固定された位置決め治具により位置決めされ、位置決め治具に位置決めされた状態のもとで対象物に向けて回転工具を推進し、対象物を加工する回転加工装置に関する。 The present invention relates to a rotary processing apparatus that is positioned by a positioning jig fixed to an object, drives a rotary tool toward the object under a state of being positioned by the positioning jig, and processes the object.

従来、鋼板等の対象物の所定箇所にボルト等を通すための穿孔を加工するのに、手持ちタイプの回転加工装置を用いている。回転加工装置はある程度の重量を有するため、作業者の負担を軽減しつつ対象物の所定箇所に回転加工装置を精度良く配置することが、対象物の加工精度（製品精度）を向上させるためにも重要な要素となる。そこで、回転加工装置の対象物に対する位置決めを行う位置決め治具を対象物に予め固定しておき、位置決め治具により回転加工装置を対象物に精度良く配置する技術が知られている。これにより、回転加工装置の回転工具（ドリル等）を対象物の所定位置に精度良く臨ませて、穿孔の加工位置のズレや穿孔の加工角度のズレ等を無くして製品精度を向上させることができる。 2. Description of the Related Art Conventionally, a hand-held rotary processing apparatus is used to process a hole for passing a bolt or the like through a predetermined portion of an object such as a steel plate. In order to improve the processing accuracy (product accuracy) of the object, the rotation processing device has a certain amount of weight, so that it is possible to accurately place the rotation processing device at a predetermined position of the object while reducing the burden on the operator. Is also an important factor. Therefore, a technique is known in which a positioning jig for positioning the rotating processing apparatus with respect to the object is fixed in advance to the object, and the rotating processing apparatus is accurately arranged on the object by the positioning jig. As a result, a rotary tool (such as a drill) of the rotary processing apparatus can be accurately faced to a predetermined position of the target object, and the product accuracy can be improved by eliminating the misalignment of the drilling processing position and the drilling processing angle. it can.

このような回転加工装置としては、例えば、特許文献１に記載された技術が知られている。特許文献１に記載された穿孔装置（回転加工装置）は、対象物に固定されるガイド部材（位置決め治具）に、係止ピンを有する複数のガイドブロックを固定している。穿孔装置は一対のガイドプレートを有するドリルアダプターを備え、各ガイドプレート間にガイドブロックを嵌合させることで穿孔装置はガイド部材に案内され、ひいては対象物の所定箇所に穿孔装置を精度良く配置することができる。そして、ドリルアダプターをガイドブロックにさらに差し込むことで、係止ピンがドリルアダプターのスライド部に係止されてロック状態となり、これによりドリルアダプターのガイドブロックからの抜け止めがなされ、穿孔装置の対象物に対する位置決めが完了する。 As such a rotary processing apparatus, for example, a technique described in Patent Document 1 is known. In the punching device (rotary processing device) described in Patent Literature 1, a plurality of guide blocks having locking pins are fixed to a guide member (positioning jig) fixed to an object. The drilling device includes a drill adapter having a pair of guide plates. By fitting a guide block between the guide plates, the drilling device is guided by the guide member, and as a result, the drilling device is accurately arranged at a predetermined position of the object. be able to. Then, when the drill adapter is further inserted into the guide block, the locking pin is locked to the slide portion of the drill adapter and locked, thereby preventing the drill adapter from coming off from the guide block, and the object of the drilling device. Positioning with respect to is completed.

穿孔装置の回転工具を回転駆動して穿孔を加工した後は、作業者によりドリルアダプターのレバーを操作するようにする。すると、レバーの操作に連動してスライド部が引き込まれて係止ピンの係止が解除されロック解除状態となる。これにより、穿孔装置を対象物から引き離せるようになり、穿孔装置をガイド部材から取り外すことができる。 After processing the drilling by rotating the rotary tool of the drilling device, the operator operates the lever of the drill adapter. Then, the slide part is pulled in conjunction with the operation of the lever, the locking of the locking pin is released, and the lock is released. As a result, the punching device can be separated from the object, and the punching device can be detached from the guide member.

しかしながら、上述の特許文献１に記載された回転加工装置によれば、回転加工装置をガイド部材から取り外す際に、作業者はレバーを操作してロック解除する必要がある。つまり、作業者は、「回転加工装置を対象物に臨ませる動作」および「回転加工装置を対象物から引き離す動作」に加えて、「回転加工装置とガイド部材とのロック状態を解除する動作」の３つの作業工程を経る必要があった。 However, according to the rotary machining apparatus described in Patent Document 1 described above, when removing the rotary machining apparatus from the guide member, the operator needs to operate the lever to release the lock. That is, in addition to the “operation for causing the rotary processing device to face the object” and the “operation for pulling the rotary processing device away from the target object”, the operator “the operation for releasing the locked state between the rotary processing device and the guide member” It was necessary to go through these three work steps.

このように、加工を終えた後に「ロック解除動作」が必要となる分、作業者には負担が掛かり、かつ作業工程が煩雑化する。そのため、作業者への負担をより軽減し得る回転加工装置の開発が望まれていた。 As described above, since the “unlocking operation” is required after finishing the processing, a burden is imposed on the operator and the work process becomes complicated. Therefore, it has been desired to develop a rotary processing apparatus that can further reduce the burden on the operator.

本発明の目的は、対象物を加工する際の作業工程を簡素化し、作業者への負担を軽減することができる回転加工装置を提供することにある。 An object of the present invention is to provide a rotary machining apparatus that can simplify a work process when machining an object and reduce a burden on an operator.

本発明の回転加工装置は、対象物に固定された位置決め治具により位置決めされ、前記位置決め治具に位置決めされた状態のもとで前記対象物に向けて回転工具を推進し、前記対象物を加工する回転加工装置であって、前記回転工具を回転自在かつ進退自在に収容する回転工具収容部材と、前記回転工具収容部材の先端側に設けられ、前記位置決め治具に設けられた位置決め孔に嵌合する嵌合部と、前記回転工具収容部材内に非回転状態でかつ前記回転工具と共に進退自在に収容されるフィード部材と、一端側が前記フィード部材に固定され、他端側が前記回転工具の径方向外側に延びて前記回転工具収容部材外に設けられるアーム部材と、前記回転工具収容部材の先端側に揺動自在に設けられ、前記位置決め治具に設けられた引掛部に引っ掛けられる引掛爪を有するカム部材と、前記アーム部材の他端側と前記カム部材との間に設けられ前記フィード部材の進退動に伴い前記カム部材を揺動駆動するとともに、前記カム部材に対する近接位置と離間位置との間で前記アーム部材の相対移動を許容する長穴が形成されたロッドと、前記アーム部材を前記離間位置に向けて付勢する弾性部材とを備えることを特徴とする。 The rotary processing apparatus of the present invention is positioned by a positioning jig fixed to an object, and a rotary tool is propelled toward the object under the state of being positioned by the positioning jig. A rotary machining device for machining, wherein the rotary tool is accommodated in a rotary tool accommodating member that accommodates the rotary tool in a freely rotatable and reciprocating manner, and a positioning hole provided in the positioning jig provided on the distal end side of the rotary tool accommodating member. A fitting portion to be fitted; a feed member that is accommodated in the rotary tool housing member in a non-rotating state and is movable together with the rotary tool; and one end side is fixed to the feed member, and the other end side is the rotary tool. An arm member extending outward in the radial direction and provided outside the rotary tool storage member, and swingably provided at the distal end side of the rotary tool storage member, and hooked on a hook portion provided in the positioning jig. A cam member having a hooking claw, and a cam member that is provided between the other end side of the arm member and the cam member to swing the cam member as the feed member moves forward and backward, and is close to the cam member It is characterized by comprising a rod in which a long hole allowing relative movement of the arm member between a position and a separation position is formed, and an elastic member for urging the arm member toward the separation position.

本発明の回転加工装置は、前記カム部材の前記ロッドとの連結点を力点とし、前記カム部材の前記回転工具収容部材との連結点を支点とし、前記引掛爪の前記引掛部との接触点を作用点としたときに、前記力点と前記支点との距離を、前記支点と前記作用点との距離よりも長くなるよう前記カム部材を形成することを特徴とする。 In the rotary machining apparatus of the present invention, the connecting point of the cam member with the rod is a force point, the connecting point of the cam member with the rotating tool housing member is a fulcrum, and the contact point of the hooking claw with the hooking portion. The cam member is formed so that a distance between the force point and the fulcrum is longer than a distance between the fulcrum and the action point when the point is an action point.

本発明の回転加工装置によれば、回転工具収容部材の先端側に、位置決め治具の位置決め孔に嵌合する嵌合部を設けるので、位置決め孔と嵌合部との嵌合により回転工具の径方向に沿う回転加工装置と対象物との相対移動を規制することができる。回転工具収容部材の先端側にカム部材を揺動自在に設け、回転工具およびフィード部材の推進により、アーム部材およびロッドを介してカム部材を揺動させ、カム部材の引掛爪を位置決め治具の引掛部に引っ掛けることができる。これにより、回転工具の軸方向に沿う回転加工装置と対象物との相対移動を規制できる（ロック状態）。回転工具およびフィード部材の後退により、アーム部材およびロッドを介してカム部材を揺動させ、引掛爪の引掛部に対する引っ掛け状態（ロック状態）を解除することができる。これにより、回転工具の軸方向に沿う回転加工装置と対象物との相対移動が許容（ロック解除状態）されて、回転加工装置を対象物から引き離すことができる。したがって、回転工具の進退動に伴って「ロック動作」および「ロック解除動作」を行わせることができ、ひいては対象物を加工する際の作業工程を簡素化し、作業者への負担を軽減することができる。回転加工装置のロック解除後には、ロッドに設けた長穴と、アーム部材を付勢する弾性部材とにより、アーム部材をカム部材に対する離間位置に戻して、カム部材をロック解除状態に戻すことができる。 According to the rotary processing apparatus of the present invention, the fitting portion that fits into the positioning hole of the positioning jig is provided on the distal end side of the rotary tool housing member. The relative movement between the rotary processing apparatus and the object along the radial direction can be restricted. A cam member is swingably provided on the distal end side of the rotary tool housing member, and the cam member is swung through the arm member and the rod by the propulsion of the rotary tool and the feed member, and the hooking claw of the cam member is moved to the positioning jig. It can be hooked on the hook. Thereby, the relative movement of the rotary processing apparatus and the object along the axial direction of the rotary tool can be restricted (locked state). By retreating the rotary tool and the feed member, the cam member can be swung via the arm member and the rod, and the hooked state (locked state) of the hooking claw with respect to the hooking portion can be released. Thereby, the relative movement of the rotary processing apparatus and the target object along the axial direction of the rotary tool is allowed (unlocked state), and the rotary processing apparatus can be pulled away from the target object. Therefore, “locking operation” and “unlocking operation” can be performed as the rotary tool advances and retreats, thereby simplifying the work process when processing the object and reducing the burden on the operator. Can do. After unlocking the rotary processing apparatus, the arm member can be returned to the separated position with respect to the cam member by the elongated hole provided in the rod and the elastic member that biases the arm member, and the cam member can be returned to the unlocked state. it can.

本発明の回転加工装置によれば、カム部材のロッドとの連結点を力点とし、カム部材の回転工具収容部材との連結点を支点とし、引掛爪の引掛部との接触点を作用点としたときに、力点と支点との距離を、支点と作用点との距離よりも長くなるようカム部材を形成するので、カム部材に作用する梃子の原理により、回転工具収容部材に回転工具による加工反力が作用したとしても、回転加工装置のロック状態を保持できる。また、ロック状態を保持できるので、弾性部材の弾性力を弱くして弾性部材を小型化できる。 According to the rotary machining apparatus of the present invention, the connecting point of the cam member with the rod is a force point, the connecting point of the cam member with the rotating tool housing member is a fulcrum, and the contact point of the hooking claw with the hooking portion is the action point. Since the cam member is formed so that the distance between the force point and the fulcrum is longer than the distance between the fulcrum and the action point, the rotary tool housing member is processed by the rotary tool according to the principle of the lever acting on the cam member. Even if the reaction force acts, the locked state of the rotary machining apparatus can be maintained. In addition, since the locked state can be maintained, the elastic member can be reduced in size by reducing the elastic force of the elastic member.

It is slidably connected via 33b. That is, the cam member 33 is driven to swing with respect to the rotary tool housing member 23 by the vertical movement of the rod 32 accompanying the forward and backward movement of the feed member 26.

カム部材３３の長手方向他側、つまり第２固定ピン３３ｂ側で、かつ短手方向他側（図中下側）には、引掛爪３５が一体に設けられている。引掛爪３５はカム部材３３から所定高さで突出するよう設けられ、引掛爪３５は位置決め治具１２の引掛部１２ｂに引っ掛けられるようになっている（図４参照）。引掛爪３５の円弧状鋼板１０側には面取部３５ａが形成され、面取部３５ａは、カム部材３３の揺動駆動時に、引掛爪３５と円弧状鋼板１０とが干渉するのを防ぐために設けられている。ここで、引掛爪３５の突出高さは、引掛部１２ｂの突出高さと略同じ寸法に設定されている。 A hooking claw 35 is integrally provided on the other side in the longitudinal direction of the cam member 33, that is, on the second fixing pin 33b side and on the other side in the lateral direction (lower side in the figure). The hooking claws 35 are provided so as to protrude from the cam member 33 at a predetermined height, and the hooking claws 35 are hooked on the hooking portions 12b of the positioning jig 12 (see FIG. 4). A chamfered portion 35a is formed on the hook-like claw 35 on the side of the arcuate steel plate 10, and the chamfered portion 35a prevents the hooking claw 35 and the arc-shaped steel plate 10 from interfering when the cam member 33 is driven to swing. Is provided. Here, the protruding height of the hooking claws 35 is set to be approximately the same as the protruding height of the hooking portion 12b.

回転工具収容部材２３の軸方向に沿う嵌合部２４寄りには、回転工具収容部材２３の内部と外部とを連通する吸塵パイプ３６が設けられている。吸塵パイプ３６の一端側（外部側）には、バキューム装置（図示せず）が接続され、吸塵パイプ３６は、ドリル２５を回転駆動して円弧状鋼板１０（Ｌ字鋼板１１）を加工する際に発生する削りくず（図示せず）を吸引するようになっている。これにより、円弧状鋼板１０の周辺に削りくずが飛散するのを防止して、作業環境の美化向上を図ることができる。 Near the fitting portion 24 along the axial direction of the rotary tool housing member 23, a dust suction pipe 36 that communicates the inside and the outside of the rotary tool housing member 23 is provided. A vacuum device (not shown) is connected to one end side (external side) of the dust suction pipe 36, and the dust suction pipe 36 rotates the drill 25 to process the arcuate steel plate 10 (L-shaped steel plate 11). The shavings (not shown) generated in the are sucked. Thereby, it is possible to prevent the shavings from being scattered around the arcuate steel plate 10 and to improve the beautification of the working environment.

次に、以上のように形成した回転加工装置２０の動作について、図面を用いて詳細に説明する。 Next, operation | movement of the rotary processing apparatus 20 formed as mentioned above is demonstrated in detail using drawing.

［第１段階］
まず、図２の実線矢印（１）に示すように、回転加工装置２０のグリップ部２１（図１参照）を作業者により把持し、回転加工装置２０の嵌合部２４を位置決め治具１２の位置決め孔１２ｃに臨ませる。このとき、電動モータ部２２のモータ２２ａの回転駆動は停止されている。 [First stage]
First, as indicated by a solid line arrow (1) in FIG. 2, an operator grips the grip portion 21 (see FIG. 1) of the rotary processing device 20, and the fitting portion 24 of the rotary processing device 20 is placed on the positioning jig 12. It faces the positioning hole 12c. At this time, the rotational drive of the motor 22a of the electric motor unit 22 is stopped.

［第２段階］
次に、回転加工装置２０を円弧状鋼板１０に近接移動させ、嵌合部２４を、スリーブ１２ｄを介して位置決め孔１２ｃに嵌合させる。このとき、回転加工装置２０を円弧状鋼板１０に向けて所定の押圧力で押し込み、嵌合部２４を完全に位置決め孔１２ｃに入り込むようにする。その後、作業者により回転加工装置２０のスイッチ（図示せず）を入れて、モータ２２ａを回転駆動させる。すると、ドリル２５が図３の実線矢印（２）に示す方向に回転駆動され、これに伴ってフィード部材２６が円弧状鋼板１０に向けて推進される。また、バキューム装置が作動し、吸塵パイプ３６には、図３の実線矢印（３）に示すような空気の流れ（負圧）が発生する。 [Second stage]
Next, the rotary processing device 20 is moved close to the arcuate steel plate 10, and the fitting portion 24 is fitted into the positioning hole 12c via the sleeve 12d. At this time, the rotary processing device 20 is pushed toward the arcuate steel plate 10 with a predetermined pressing force so that the fitting portion 24 completely enters the positioning hole 12c. Thereafter, the operator turns on a switch (not shown) of the rotary processing device 20 to rotate the motor 22a. Then, the drill 25 is rotationally driven in the direction shown by the solid line arrow (2) in FIG. 3, and the feed member 26 is propelled toward the arcuate steel plate 10 along with this. Further, the vacuum device is activated, and an air flow (negative pressure) as shown by a solid line arrow (3) in FIG.

［第３段階］
回転加工装置２０を円弧状鋼板１０に対して垂直保持した状態で、図４の実線矢印（４）に示すように、ドリル２５およびフィード部材２６が円弧状鋼板１０に向けて推進を続ける。すると、フィード部材２６の推進に伴って、ロック機構３０のアーム部材３１が第１スリット２７内を移動して円弧状鋼板１０に近接していく。このとき、コイルバネ３４の押圧力により摺動ピン３１ａは長穴３２ａ内をスライドすることが無い。したがって、ロッド３２についても円弧状鋼板１０に近接していく。 [Stage 3]
With the rotary processing device 20 held vertically with respect to the arcuate steel plate 10, the drill 25 and the feed member 26 continue to propel toward the arcuate steel plate 10 as indicated by the solid line arrow (4) in FIG. 4. Then, as the feed member 26 is propelled, the arm member 31 of the lock mechanism 30 moves in the first slit 27 and approaches the arcuate steel plate 10. At this time, the sliding pin 31a does not slide in the long hole 32a by the pressing force of the coil spring 34. Therefore, the rod 32 also approaches the arcuate steel plate 10.

その後、ロッド３２の円弧状鋼板１０に対する近接に伴って、第１固定ピン３３ａの中心軸Ｃ１および第２固定ピン３３ｂの中心軸Ｃ２を中心として、図４の実線矢印（５）および（６）に示すようにカム部材３３が揺動する。そして、カム部材３３の揺動に伴って、引掛爪３５が位置決め治具１２の引掛部１２ｂに引っ掛かり、ロック機構３０による回転加工装置２０の位置決め治具１２に対するロック動作が完了する。 Thereafter, as the rod 32 approaches the arcuate steel plate 10, solid arrows (5) and (6) in FIG. 4 centering on the central axis C1 of the first fixing pin 33a and the central axis C2 of the second fixing pin 33b. As shown, the cam member 33 swings. Then, as the cam member 33 swings, the hooking claws 35 are hooked on the hooking portion 12b of the positioning jig 12, and the locking operation of the rotary machining apparatus 20 to the positioning jig 12 by the lock mechanism 30 is completed.

モータ２２ａを継続して回転駆動することにより、回転加工装置２０を位置決め治具１２に位置決めした状態のもとで、ドリル２５およびフィード部材２６が円弧状鋼板１０に向けてさらに推進していく。このとき、フィード部材２６の推進力によりコイルバネ３４は押し縮められ、摺動ピン３１ａは長穴３２ａ内をスライドするようになる。その後、ドリル２５が円弧状鋼板１０に到達して、円弧状鋼板１０およびＬ字鋼板１１に穿孔を形成していく。 By continuously rotating the motor 22a, the drill 25 and the feed member 26 are further propelled toward the arcuate steel plate 10 with the rotary processing device 20 positioned on the positioning jig 12. At this time, the coil spring 34 is pressed and contracted by the propulsive force of the feed member 26, and the sliding pin 31a slides in the elongated hole 32a. Thereafter, the drill 25 reaches the arcuate steel plate 10 to form perforations in the arcuate steel plate 10 and the L-shaped steel plate 11.

回転加工装置２０による加工時においては、図５に示すようにドリル２５にはフィード部材２６からのフィード力Ｆと、円弧状鋼板１０からの加工反力Ｆとが負荷される。加工反力Ｆは、回転工具収容部材２３を円弧状鋼板１０から離間させる方向に作用するが、回転加工装置２０は、位置決め治具１２に対してロック機構３０により上下左右方向に強固にロックされた状態となっている。したがって、加工反力Ｆによって回転加工装置２０が位置決め治具１２から外れたり、がたついたりするようなことは無い。 At the time of processing by the rotary processing device 20, as shown in FIG. 5, the feed force F from the feed member 26 and the processing reaction force F from the arcuate steel plate 10 are loaded on the drill 25. The processing reaction force F acts in a direction in which the rotary tool housing member 23 is separated from the arcuate steel plate 10, but the rotary processing device 20 is firmly locked in the vertical and horizontal directions by the lock mechanism 30 with respect to the positioning jig 12. It is in the state. Therefore, the rotary processing device 20 is not detached from the positioning jig 12 or rattled by the processing reaction force F.

カム部材３３の引掛爪３５と、位置決め治具１２の引掛部１２ｂとの接触点ＦＰには、回転加工装置２０による加工時において、カム部材３３を図中破線矢印の方向に回転させようとする負荷Ｆが掛かる。ここで、カム部材３３とロッド３２との連結点（第１固定ピン３３ａ）を力点とし、カム部材３３と回転工具収容部材２３との連結点（第２固定ピン３３ｂ）を支点とし、接触点ＦＰを作用点とする。力点にはコイルバネ３４の押圧力が負荷され、さらには、力点と支点との距離Ｌ１が支点と作用点との距離Ｌ２よりも長い長さ寸法となるようカム部材３３の形状を設定している。したがって、カム部材３３に作用する梃子の原理により、接触点ＦＰに作用する負荷Ｆによりカム部材３３が回転するようなことは無い。また、ドリル２５の軸方向に沿う支点と作用点との距離Ｌ３の長さ寸法をより短くあるいは力点と支点との距離Ｌ１をより長くすれば、カム部材３３は負荷Ｆによりさらに回転し難くなる。 At the contact point FP between the hooking claw 35 of the cam member 33 and the hooking portion 12b of the positioning jig 12, the cam member 33 tries to rotate in the direction of the broken line arrow in the drawing during processing by the rotary processing device 20. Load F is applied. Here, a connecting point (first fixing pin 33a) between the cam member 33 and the rod 32 is used as a force point, and a connecting point (second fixing pin 33b) between the cam member 33 and the rotary tool housing member 23 is used as a fulcrum, and a contact point. Let FP be the point of action. The pressing force of the coil spring 34 is applied to the force point, and the shape of the cam member 33 is set so that the distance L1 between the force point and the fulcrum is longer than the distance L2 between the fulcrum and the action point. . Therefore, due to the principle of the lever acting on the cam member 33, the cam member 33 is not rotated by the load F acting on the contact point FP. Further, if the length dimension of the distance L3 between the fulcrum and the action point along the axial direction of the drill 25 is made shorter or the distance L1 between the force point and the fulcrum is made longer, the cam member 33 becomes more difficult to rotate due to the load F. .

［第４段階］
回転加工装置２０による加工を進めていくと、図６の実線矢印（７）に示すように、さらに摺動ピン３１ａは長穴３２ａ内をスライドしていき、図６の実線矢印（８）に示すように、ドリル２５は円弧状鋼板１０およびＬ字鋼板１１を貫通し、円弧状鋼板１０およびＬ字鋼板１１には穿孔Ｈが形成され、回転加工装置２０による加工が終了する。このとき、コイルバネ３４は略完全に押し縮められた状態になる。なお、回転加工装置２０による加工時は、バキューム装置は作動し続けており、円弧状鋼板１０およびＬ字鋼板１１の削りくずは吸塵パイプ３６を介して外部の廃棄場所（図示せず）に廃棄される。 [Fourth stage]
As the processing by the rotary processing device 20 proceeds, the sliding pin 31a further slides in the elongated hole 32a as shown by the solid line arrow (7) in FIG. 6, and the solid line arrow (8) in FIG. As shown, the drill 25 penetrates the arc-shaped steel plate 10 and the L-shaped steel plate 11, and a hole H is formed in the arc-shaped steel plate 10 and the L-shaped steel plate 11. At this time, the coil spring 34 is almost completely compressed. Note that, during machining by the rotary machining device 20, the vacuum device continues to operate, and the shavings of the arc-shaped steel plate 10 and the L-shaped steel plate 11 are discarded to an external disposal place (not shown) via the dust suction pipe 36. The

［第５段階］
円弧状鋼板１０およびＬ字鋼板１１の加工が終了し、回転加工装置２０を位置決め治具１２から取り外すには、モータ２２ａを制御して、フィード部材２６およびドリル２５を図３に示す位置にまで後退させる。すると、上述したフィード部材２６およびドリル２５の推進動作とは逆の動作を辿ってロック機構３０のロック状態が解除され、ロック機構３０は図３に示す初期状態に復帰する。これにより、回転加工装置２０を位置決め治具１２から引き離して取り外せるようになる。 [Fifth stage]
When the processing of the arc-shaped steel plate 10 and the L-shaped steel plate 11 is completed and the rotary processing apparatus 20 is removed from the positioning jig 12, the motor 22a is controlled to bring the feed member 26 and the drill 25 to the positions shown in FIG. Retreat. Then, the lock mechanism 30 is unlocked by following the reverse of the propulsion operation of the feed member 26 and the drill 25 described above, and the lock mechanism 30 returns to the initial state shown in FIG. As a result, the rotary processing apparatus 20 can be detached from the positioning jig 12 and removed.

以上詳述したように、本実施の形態に係る回転加工装置２０によれば、回転工具収容部材２３の先端側に、位置決め治具１２の位置決め孔１２ｃに嵌合する嵌合部２４を設けたので、位置決め孔１２ｃと嵌合部２４との嵌合によりドリル２５の径方向に沿う回転加工装置２０と円弧状鋼板１０（Ｌ字鋼板１１）との相対移動を規制することができる。 As described in detail above, according to the rotary machining apparatus 20 according to the present embodiment, the fitting portion 24 that fits into the positioning hole 12c of the positioning jig 12 is provided on the distal end side of the rotary tool housing member 23. Therefore, the relative movement between the rotary processing device 20 and the arcuate steel plate 10 (L-shaped steel plate 11) along the radial direction of the drill 25 can be restricted by the fitting of the positioning hole 12c and the fitting portion 24.

回転工具収容部材２３の先端側にカム部材３３を揺動自在に設け、ドリル２５およびフィード部材２６の推進により、アーム部材３１およびロッド３２を介してカム部材３３を揺動させ、カム部材３３の引掛爪３５を位置決め治具１２の引掛部１２ｂに引っ掛けることができる。これにより、ドリル２５の軸方向に沿う回転加工装置２０と円弧状鋼板１０（Ｌ字鋼板１１）との相対移動を規制できる（ロック状態）。 A cam member 33 is swingably provided on the distal end side of the rotary tool housing member 23, and the cam member 33 is swung via the arm member 31 and the rod 32 by the propulsion of the drill 25 and the feed member 26. The hooking claw 35 can be hooked on the hooking portion 12 b of the positioning jig 12. Thereby, the relative movement of the rotary machining apparatus 20 along the axial direction of the drill 25 and the arc-shaped steel plate 10 (L-shaped steel plate 11) can be restricted (locked state).

ドリル２５およびフィード部材２６の後退により、アーム部材３１およびロッド３２を介してカム部材３３を揺動させ、引掛爪３５の引掛部１２ｂに対する引っ掛け状態（ロック状態）を解除することができる。これにより、ドリル２５の軸方向に沿う回転加工装置２０と円弧状鋼板１０（Ｌ字鋼板１１）との相対移動が許容（ロック解除状態）されて、回転加工装置２０を円弧状鋼板１０（Ｌ字鋼板１１）から引き離すことができる。 By retreating the drill 25 and the feed member 26, the cam member 33 can be swung via the arm member 31 and the rod 32, and the hooked state (locked state) of the hooking claws 35 with respect to the hooking portion 12b can be released. As a result, relative movement between the rotary processing device 20 and the arcuate steel plate 10 (L-shaped steel plate 11) along the axial direction of the drill 25 is allowed (unlocked state), and the rotary processing device 20 is moved to the arcuate steel plate 10 (L It can be pulled away from the shaped steel plate 11).

したがって、回転工具としてのドリル２５の進退動に伴って「ロック動作」および「ロック解除動作」を行わせることができ、ひいては加工する際の作業工程を簡素化し、作業者への負担を軽減することができる。回転加工装置２０のロック解除後には、ロッド３２に設けた長穴３２ａと、ロッド３２とアーム部材３１との間に設けたコイルバネ３４とにより、アーム部材３１をカム部材３３に対する離間位置に戻して、カム部材３３をロック解除状態に戻すことができる。 Accordingly, the “locking operation” and the “unlocking operation” can be performed in accordance with the advance and retreat of the drill 25 as the rotary tool, and thus the work process at the time of machining is simplified and the burden on the operator is reduced. be able to. After unlocking the rotary processing device 20, the arm member 31 is returned to the separated position with respect to the cam member 33 by the elongated hole 32 a provided in the rod 32 and the coil spring 34 provided between the rod 32 and the arm member 31. The cam member 33 can be returned to the unlocked state.

また、本実施の形態に係る回転加工装置２０によれば、第１固定ピン３３ａ（中心軸Ｃ１）を力点とし、第２固定ピン３３ｂ（中心軸Ｃ２）を支点とし、接触点ＦＰを作用点としたときに、力点と支点との距離Ｌ１を、支点と作用点との距離Ｌ２よりも長くなるようカム部材３３を形成した。したがって、カム部材３３に作用する梃子の原理により、回転工具収容部材２３にドリル２５による加工反力Ｆが作用したとしても、回転加工装置２０のロック状態を保持できる。また、ロック状態を保持できるので、コイルバネ３４の弾性力を弱くしてコイルバネ３４を小型化できる。 Further, according to the rotary machining apparatus 20 according to the present embodiment, the first fixing pin 33a (center axis C1) is a force point, the second fixing pin 33b (center axis C2) is a fulcrum, and the contact point FP is an action point. The cam member 33 is formed so that the distance L1 between the force point and the fulcrum is longer than the distance L2 between the fulcrum and the action point. Therefore, due to the principle of the lever acting on the cam member 33, even when the machining reaction force F by the drill 25 acts on the rotary tool housing member 23, the locked state of the rotary machining apparatus 20 can be maintained. Further, since the locked state can be maintained, the elastic force of the coil spring 34 can be weakened and the coil spring 34 can be downsized.
