Description

本発明は、光ファイバを切断する光ファイバ切断器における切断刃の高さを調整する刃高調整治具及びそれを用いた刃高調整方法に関する。   The present invention relates to a blade height adjusting jig for adjusting the height of a cutting blade in an optical fiber cutter for cutting an optical fiber, and a blade height adjusting method using the same.

一般に、光ファイバ相互、光ファイバと他の光学部品等とを光学的に接続するには、予め光ファイバの端部をその光ファイバの軸心に対して垂直に切断することが行われる。この切断には、一般に光ファイバ切断器が用いられる。   In general, in order to optically connect optical fibers, optical fibers and other optical components, or the like, the end portions of the optical fibers are cut in advance perpendicularly to the axis of the optical fibers. An optical fiber cutter is generally used for this cutting.

図３は光ファイバ切断器１の概念図を示したもので、互いに並列に配置された一対の光ファイバホルダ台２・２上に光ファイバ３を載置し、光ファイバホルダ台２・２上の光ファイバ３を図示しないホルダ蓋で押えて光ファイバ３を光ファイバホルダ台２・２上に固定し、この状態で光ファイバホルダ台２・２の面よりも高さが若干高い、例えば高さｔに調整された切断刃４を図示の実線の位置から点線の切断刃４'の位置まで、光ファイバ３の軸線を直角に横断するように移動させることにより、光ファイバ３の表面に傷を付け光ファイバ３を切断するものである。   FIG. 3 is a conceptual diagram of the optical fiber cutter 1. The optical fiber 3 is placed on a pair of optical fiber holder bases 2, 2 arranged in parallel with each other, and the optical fiber holder bases 2, 2 are The optical fiber 3 is pressed by a holder lid (not shown) to fix the optical fiber 3 on the optical fiber holder bases 2 and 2, and in this state, the height is slightly higher than the surface of the optical fiber holder bases 2 and 2. The surface of the optical fiber 3 is scratched by moving the cutting blade 4 adjusted to t from the position of the solid line shown in the figure to the position of the dotted cutting blade 4 ′ so as to cross the axis of the optical fiber 3 at a right angle. And the optical fiber 3 is cut.

この光ファイバの切断を行う際、切断刃４の高さｔは適切な値でなければ、光ファイバ３を適切に切断することができない。即ち、高さｔが小さいときは光ファイバ３を切断することができず、また、大きいときは光ファイバ３の切断面に不要な傷を付けて切断面を損傷してしまう。このため、切断刃４の高さｔは光ファイバ３の切断作業の前に適切な値に調整する必要がある。（例えば、特許文献１〜２参照）
通常、上記切断刃４の高さｔは２０〜３０μｍとなるように調整される。なお、この調整作業は、図示しない刃高調整ねじを回転させることにより行われる。 When cutting the optical fiber, the optical fiber 3 cannot be cut properly unless the height t of the cutting blade 4 is an appropriate value. That is, when the height t is small, the optical fiber 3 cannot be cut, and when the height t is large, unnecessary cuts are made on the cut surface of the optical fiber 3 to damage the cut surface. For this reason, it is necessary to adjust the height t of the cutting blade 4 to an appropriate value before cutting the optical fiber 3. (For example, see Patent Documents 1 and 2)
Usually, the height t of the cutting blade 4 is adjusted to be 20 to 30 μm. This adjustment operation is performed by rotating a blade height adjustment screw (not shown).

図４は特許文献２に記載された調整方法の一例を示したものである。図４において、１１は刃高調整治具であり、刃高調整治具１１は中央部に溝１２が形成された平板形状をしており、その溝１２の一端側１３が調整しようとする切断刃４の高さよりも多く削られ、他端側１４が調整される切断刃４の高さよりも少なく削られ、中央部１５が刳り貫かれた形状を成している。そしてこれを使用して切断刃４の高さを調整する場合には、図５に示すように、溝を下側にして溝が切断刃の移動方向と平行になるように光ファイバホルダ台２・２上に載置し、この状態で溝が多く削られた方向から少なく削られた方向に切断刃を移動させて、切断刃が多く削られた箇所を通過し、少なく削られた箇所を通過しないような高さに調整される。これにより、切断刃４を上記削られた範囲内に高さが調整される。   FIG. 4 shows an example of the adjustment method described in Patent Document 2. In FIG. 4, reference numeral 11 denotes a blade height adjusting jig. The blade height adjusting jig 11 has a flat plate shape with a groove 12 formed in the center, and the cutting blade 4 to be adjusted at one end side 13 of the groove 12. The other end side 14 is cut to a height less than the height of the cutting blade 4 to be adjusted, and the central portion 15 is punched. And when adjusting the height of the cutting blade 4 using this, as shown in FIG. 5, the optical fiber holder base 2 is arranged so that the groove is on the lower side and the groove is parallel to the moving direction of the cutting blade.・ Mounted on 2 and moved the cutting blade from the direction in which many grooves were cut in this state to the direction in which the cutting blades were cut to a small extent. The height is adjusted so as not to pass. As a result, the height of the cutting blade 4 is adjusted within the shaved range.

また、切断刃４の刃高を図６に示すような刃高調整治具３０によって行うことも行われていた。即ち、始めに、図６イに示すように、刃高調整治具３０の底面３１を平面度の保たれた基準面３２上に接触させて配置し、この状態で摘み３３を回動させて指示針３４をゼロに合わせる。これによって、刃高調整治具３０の底面３１と触針３５の先端３５'とが同一面でゼロに調整されたことになる。次に図６ロに示すように、刃高調整治具３０の底面３１を光ファイバホルダ台２上に載置して、切断刃４を触針３５の先端３５'に軽く接触するように位置合わせを行い、ダイヤルゲージの目盛りが目的の高さになるように切断刃の高さを調整する。   Further, the blade height of the cutting blade 4 is also performed by a blade height adjusting jig 30 as shown in FIG. That is, first, as shown in FIG. 6A, the bottom surface 31 of the blade height adjusting jig 30 is placed in contact with the reference surface 32 where flatness is maintained, and the knob 33 is rotated in this state to indicate Set the needle 34 to zero. As a result, the bottom surface 31 of the blade height adjusting jig 30 and the tip 35 'of the stylus 35 are adjusted to zero on the same surface. Next, as shown in FIG. 6B, the bottom surface 31 of the blade height adjusting jig 30 is placed on the optical fiber holder base 2, and the cutting blade 4 is aligned so as to lightly contact the tip 35 'of the stylus 35. And adjust the height of the cutting blade so that the dial gauge scale is at the desired height.

しかしながら、図４に示した刃高調整治具１１は、中央部に溝１２が形成された平板形状をしており、その溝１２の一端側１３が調整しようとする切断刃４の高さよりも多く削られ、他端側１４が調整される切断刃４の高さよりも少なく削られ、中央部１５が刳り貫かれた複雑な形状を成しており、これを構成するための加工が複雑で、加工製作が高価になるという課題があった。また、刃高調整治具１１は平板形状を成しているため、刃高調整過程で切断刃４を移動させて刃高を調べる際に切断刃が刃高調整治具１１に当たった際、刃高調整治具１１が平板形状を成していることから刃高調整治具１１が容易に移動することが困難であり、切断刃に傷を付けてしまうことの課題があった。   However, the blade height adjusting jig 11 shown in FIG. 4 has a flat plate shape in which a groove 12 is formed at the center, and one end side 13 of the groove 12 is larger than the height of the cutting blade 4 to be adjusted. The other end side 14 is shaved less than the height of the cutting blade 4 to be adjusted, and the central portion 15 has a complicated shape that is pierced, and the processing for configuring this is complicated, There was a problem that processing and manufacturing became expensive. Further, since the blade height adjusting jig 11 has a flat plate shape, when the cutting blade hits the blade height adjusting jig 11 when the cutting blade 4 is moved during the blade height adjusting process to check the blade height, the blade harmonics are adjusted. Since the adjusting jig 11 has a flat plate shape, it is difficult for the blade height adjusting jig 11 to easily move, and there is a problem that the cutting blade is damaged.

また一般にホルダ台は図７に示すようにホルダ台の表面にゴム部材等の弾性部材２'が貼り付けられており、研磨工程によって弾性部材２'をホルダ台２の表面と同一平面となるように研磨しようとしても、研磨工程で弾性部材２'の変形により、弾性部材２'が歪み、このため、弾性部材２'の表面がホルダ台２の表面よりも若干高くなるように加工される。このため、上記刃高調整治具１１をホルダ台２の上に乗せた際、実質的に弾性部材２'の表面にホルダ台２が載せられる形となり、この結果、ホルダ台２からの高さに調整されることになる。この結果、実際に光ファイバ３をホルダ台２に載せられた際には光ファイバ３の接触面は弾性部材２'の変形によりホルダ台２の表面と同一にセットされたものと異なり、正確に調整されないという課題があった。なお、弾性部材２'の表面が上記のようにホルダ台２の表面よりも若干高くなるように加工されるても、実際の光ファイバ切断時においては、光ファイバ３は若干高くなるように形成された弾性部材２'を窪ませて、弾性部材２'周囲のホルダ台２の表面に接するように戴置されるので、問題になることがない。   In general, as shown in FIG. 7, the holder base has an elastic member 2 'such as a rubber member attached to the surface of the holder base so that the elastic member 2' becomes flush with the surface of the holder base 2 by the polishing process. Even if it is going to be polished, the elastic member 2 ′ is deformed by the deformation of the elastic member 2 ′ in the polishing step, so that the surface of the elastic member 2 ′ is processed to be slightly higher than the surface of the holder base 2. For this reason, when the blade height adjusting jig 11 is placed on the holder base 2, the holder base 2 is substantially placed on the surface of the elastic member 2 '. As a result, the height from the holder base 2 is increased. Will be adjusted. As a result, when the optical fiber 3 is actually placed on the holder base 2, the contact surface of the optical fiber 3 is different from that which is set to be the same as the surface of the holder base 2 due to the deformation of the elastic member 2 ′. There was a problem that it was not adjusted. Even if the surface of the elastic member 2 ′ is processed to be slightly higher than the surface of the holder base 2 as described above, the optical fiber 3 is formed to be slightly higher at the time of actual optical fiber cutting. Since the elastic member 2 ′ thus formed is recessed and placed so as to be in contact with the surface of the holder base 2 around the elastic member 2 ′, there is no problem.

また、図６に示す刃高調整治具３０は、ホルダ台間に停止させられた切断刃４の頂点と刃高調整治具３０の触針３５とを合わせて測定する方法が、切断刃の頂点と触針３５とが共に狭い面積であるために両者を探し求めることが難しく、調整時間に長時間を要するという課題があった。また、切断刃４を移動させての高さを調整する方法も考えられるが、この場合は切断刃４の刃高を調整する際、切断刃４が触針３５にぶつかった際に、刃高調整治具３０がホルダ台上で容易に移動することができず、切断刃４に傷が付くという課題が発生する。また、更に前記弾性部材２'の存在により正しく刃高が調整されないという課題があった。   In addition, the blade height adjusting jig 30 shown in FIG. 6 has a method in which the top of the cutting blade 4 stopped between the holder bases and the stylus 35 of the blade height adjusting jig 30 are measured together with the top of the cutting blade. Since both the stylus 35 have a small area, it is difficult to search for both, and there is a problem that a long time is required for adjustment. A method of adjusting the height by moving the cutting blade 4 is also conceivable. In this case, when adjusting the blade height of the cutting blade 4, the blade harmonics when the cutting blade 4 hits the stylus 35. The adjusting jig 30 cannot easily move on the holder base, and a problem arises that the cutting blade 4 is damaged. Further, there is a problem that the blade height is not adjusted correctly due to the presence of the elastic member 2 '.

本発明は、かかる点に鑑みなされたもので、その第一の発明は、間隔を隔てて配置された一対の光ファイバホルダ台間に、そのホルダ台に沿って移動する切断刃が配置され、両ホルダ台間に跨って配置される光ファイバを前記切断刃の移動によって傷付け、光ファイバを切断するための光ファイバ切断器における前記切断刃の刃高を調整する調整治具であって、ホルダ台に搭載され、中央部外周表面が調整される切断刃の高さ付近に減径加工された円柱体であることを特徴とする光ファイバ切断器の刃高調整治具である。   The present invention has been made in view of such a point, the first invention is arranged between a pair of optical fiber holder bases arranged at intervals, a cutting blade moving along the holder base, An adjustment jig for adjusting a blade height of the cutting blade in an optical fiber cutter for cutting an optical fiber by damaging an optical fiber disposed between both holder stands by moving the cutting blade, A blade height adjusting jig for an optical fiber cutter, which is a cylindrical body mounted on a table and having a reduced diameter near the height of a cutting blade whose outer peripheral surface is adjusted at the center.

更に第２の発明は、間隔を隔てて配置された一対の光ファイバホルダ台間に、そのホルダ台に沿って移動する切断刃が配置され、両ホルダ台間に跨って配置される光ファイバを前記切断刃の移動によって傷付け、光ファイバを切断するための光ファイバ切断器における前記切断刃を所定値Δに高さ調整する光ファイバ切断器の刃高調整方法において、中央部外周表面が前記所定値Δの前と後に減径加工された２種類の円柱状測定ゲージを前記ホルダ台間に跨って配置し、切断刃の移動によって切断刃が前記ホルダ台に搭載された一方の測定ゲージの中央部外周に接触せず、他方の測定ゲージの中央部外周に接触するように切断刃の高さを調整することを特徴とする光ファイバ切断器の刃高調整方法である。   Further, according to a second aspect of the present invention, there is provided an optical fiber disposed between a pair of optical fiber holder bases, wherein a cutting blade moving along the holder base is disposed between the pair of optical fiber holder bases. In the method of adjusting the height of the cutting edge of the optical fiber cutter in which the height of the cutting blade in the optical fiber cutter for cutting the optical fiber is damaged by the movement of the cutting blade is adjusted to a predetermined value Δ, Two types of cylindrical measuring gauges reduced in diameter before and after the value Δ are arranged between the holder bases, and the cutting blade is mounted on the holder base by moving the cutting blade. The blade height adjusting method of the optical fiber cutter is characterized in that the height of the cutting blade is adjusted so as not to contact the outer periphery of the portion but to contact the outer periphery of the central portion of the other measurement gauge.

本願は上記第１の発明によって、断面外周形状が円形に構成されているため、切断刃が刃高調整治具にぶつかっても容易に刃高調整治具が回転して切断刃に傷を付けることがなく、また、構造が簡単なため、安価にこれを構成することができる。
また、第２の発明によって、それぞれの刃高調整治具に形成された減径加工の大きさの間に切断刃に傷を付けることなく、正確に切断刃の高さを調整することができる特徴を有する。 According to the first aspect of the present invention, since the outer peripheral shape of the cross section is configured to be circular, even if the cutting blade hits the blade height adjusting jig, the blade height adjusting jig can easily rotate and scratch the cutting blade. In addition, since the structure is simple, it can be constructed at low cost.
In addition, according to the second invention, the height of the cutting blade can be accurately adjusted without damaging the cutting blade between the sizes of the diameter reducing processes formed in the respective blade height adjusting jigs. Have

図１は本発明の一実施形態における刃高調整治具３０を示すものである。刃高調整治具は、中央部３１の外周表面が減径加工された円柱体で形成されている。この減径加工の大きさｙは調整される切断刃の高さ付近の大きさに形成される。刃高調整治具３０は所定径Ｄの大きさの円柱体、例えばステンレス材製からなる棒状体を回転旋盤によって保持し、その中央部の外周を削ることによって作成される。このようにして作成される刃高調整治具３０は表１に示すように、切断刃の高さ調整される値付近のものが複数種作成される。   FIG. 1 shows a blade height adjusting jig 30 according to an embodiment of the present invention. The blade height adjusting jig is formed of a cylindrical body in which the outer peripheral surface of the central portion 31 is subjected to diameter reduction processing. The size y of the diameter reduction processing is formed in the size near the height of the cutting blade to be adjusted. The blade height adjusting jig 30 is formed by holding a cylindrical body having a predetermined diameter D, for example, a rod-shaped body made of stainless steel by a rotary lathe and cutting the outer periphery of the central portion. As shown in Table 1, a plurality of types of blade height adjustment jigs 30 created in this way are created in the vicinity of the value for adjusting the height of the cutting blade.

図２は本実施形態の刃高調整治具３０を用いて切断刃の刃高を調整する手段を説明するためのものである。ここで例えば、切断刃の高さを２５〜３０μｍの高さに調整する場合について説明する。   FIG. 2 is a view for explaining means for adjusting the blade height of the cutting blade using the blade height adjusting jig 30 of the present embodiment. Here, for example, the case where the height of the cutting blade is adjusted to a height of 25 to 30 μm will be described.

始め、始め表１中のNo.３の刃高調整治具３０を選択して、図示のように、No.３の刃高調整治具３０を弾性部材２'が配置されていないホルダ台２上に配置し、ここで、切断刃４を実線の位置から破線で示される切断刃４'まで移動させる。この際、切断刃４が刃高調整治具３０にぶつかっても刃高調整治具３０の外径形状が円形に構成されているため、刃高調整治具３０は容易に回転して切断刃から逃げることができる。このため、切断刃４は傷が付くことが無い。このようにして、No.３の刃高調整治具３０の縮径部分を切断刃が通過できるように、切断刃を図示しない刃高調整摘みを回転させることにより、切断刃を調整する。   First, the No. 3 blade height adjusting jig 30 in Table 1 is first selected, and the No. 3 blade height adjusting jig 30 is placed on the holder base 2 on which the elastic member 2 'is not arranged as shown in the figure. Here, the cutting blade 4 is moved from the position of the solid line to the cutting blade 4 ′ indicated by the broken line. At this time, even if the cutting blade 4 collides with the blade height adjusting jig 30, the outer diameter shape of the blade height adjusting jig 30 is circular, so that the blade height adjusting jig 30 easily rotates and escapes from the cutting blade. Can do. For this reason, the cutting blade 4 is not damaged. In this way, the cutting blade is adjusted by rotating the blade height adjusting knob (not shown) so that the cutting blade can pass through the reduced diameter portion of the No. 3 blade height adjusting jig 30.

次にNo.２の刃高調整治具３０を選択して、上記No.３の刃高調整治具３０と同様にセットして切断刃４の移動を前記と同様に行う。これによって、切断刃４がNo.２の刃高調整治具３０の減径部分を通過可能かどうかを調べる。ここで切断刃がNo.２の刃高調整治具３０にぶつかる（刃高調整治具３０が動いたり、回転したりする）場合は、切断刃の高さが２５〜３０μｍの高さに調整されたことになる。ここでもし、切断刃４がNo.２の刃高調整治具３０にぶつからない場合は、再度上記No.３の刃高調整治具３０が通過可能でNo.２の刃高調整治具３０が通過しないようになるまで切断刃の高さを調整する。   Next, the No. 2 blade height adjusting jig 30 is selected, set in the same manner as the No. 3 blade height adjusting jig 30, and the cutting blade 4 is moved in the same manner as described above. In this way, it is examined whether or not the cutting blade 4 can pass through the reduced diameter portion of the No. 2 blade height adjusting jig 30. Here, when the cutting blade collides with the No. 2 blade height adjusting jig 30 (the blade height adjusting jig 30 moves or rotates), the height of the cutting blade is adjusted to a height of 25 to 30 μm. It will be. Here, if the cutting blade 4 does not collide with the No. 2 blade height adjusting jig 30, the No. 3 blade height adjusting jig 30 can pass again, and the No. 2 blade height adjusting jig 30 does not pass again. Adjust the height of the cutting blade until

切断刃の高さが２５〜３０μｍ以外の高さに調整する場合は、それぞれ他の組み合わせの刃高調整治具３０を用いて同様にして調整される。   When the height of the cutting blade is adjusted to a height other than 25 to 30 μm, the blade height adjustment jig 30 of another combination is adjusted in the same manner.

本実施形態の刃高調整治具３０は上記のとおり、外周形状が円形になっている。このため、切断刃の刃高調整において、切断刃が刃高調整治具３０にぶつかっても刃高調整治具３０は容易に回転し、この結果、切断刃に傷を付けることが無い。
また、この調整時に切断刃が刃高調整治具３０にほんの僅かに接触した場合であっても、刃高調整治具３０が容易に動くのでその接触を容易に把握することができ、正確に高さ調整を行うことができる。
更に、本実施形態のように、刃高調整治具３０を弾性部材２'が配置されていないホルダ台２上に配置することにより、弾性部材２'の影響を受けずに高さ調整することができ、その高さの範囲を正確に設定することができる。 As described above, the blade height adjusting jig 30 of the present embodiment has a circular outer peripheral shape. For this reason, in adjusting the blade height of the cutting blade, even if the cutting blade hits the blade height adjusting jig 30, the blade height adjusting jig 30 easily rotates, and as a result, the cutting blade is not damaged.
Further, even when the cutting blade is in slight contact with the blade height adjusting jig 30 during this adjustment, the blade height adjusting jig 30 moves easily so that the contact can be easily grasped, and the height is accurately determined. Adjustments can be made.
Further, as in the present embodiment, by arranging the blade height adjusting jig 30 on the holder base 2 where the elastic member 2 'is not arranged, the height can be adjusted without being affected by the elastic member 2'. And the range of the height can be set accurately.
