【００１１】 本考案は、以上の構成よりなる外径研削機用芯出し治具である。The present invention is a centering jig for an outer diameter grinding machine having the above configuration.
【００１２】[0012]
第１の考案では、たとえば、図１に示したように、連結部１４の一端側に固定 されたクランプ部６は、固定クランプ１２と、可動クランプ１１とを有し、それ ぞれ、６、６´クランプ軸１０で軸支されている。また連結部１４のもう一端側 には、ワ−クを載せるためのワ−ク載置部７が設けられている。いま、ワ−クを 外径研削機の固定棒５（図４参照）にセットする場合、まず、治具を固定棒５の 下から当てがい、固定棒をクランプ部でクランプして、治具を固定棒５に一体的 に固定する。つづいて、ワ−ク１（図５参照）をワ−ク載置部７に載せると、固 定棒センタ−延長線上から、ワ−ク載置部７のワ−ク１との接触部まで垂直に降 ろした距離がワ−ク半径に等しいから、固定棒５のセンタ−とワ−ク１のセンタ −とが自ずと一致する。こうしておいてワ−ク１を固定棒５に当接させ、外径研 削機のもう一方側の固定棒５´とで、ワ−ク１を両端側から固定する。しかるの ち、治具をはずす。 In the first invention, for example, as shown in FIG. 1, the clamp portion 6 fixed to one end side of the connecting portion 14 has a fixed clamp 12 and a movable clamp 11, and the clamp portions 6 and 6, respectively. It is supported by a 6'clamp shaft 10. On the other end side of the connecting portion 14, a work mounting portion 7 for mounting a work is provided. Now, when setting the work on the fixed rod 5 (see FIG. 4) of the outer diameter grinding machine, first apply the jig from below the fixed rod 5, clamp the fixed rod with the clamp part, and fix the jig. Is integrally fixed to the fixing rod 5. Next, when the work 1 (see FIG. 5) is placed on the work placing part 7, from the fixed rod center extension line to the contact part of the work placing part 7 with the work 1. Since the vertically lowered distance is equal to the work radius, the center of the fixed rod 5 and the center of the work 1 naturally coincide with each other. In this way, the work 1 is brought into contact with the fixed rod 5, and the work 1 is fixed from both ends with the fixed rod 5'on the other side of the outer diameter grinding machine. After that, remove the jig.
【００１３】 第２の考案では、たとえば、図３に示したように、外径研削機の固定棒に治具 を固定し、固定棒の中心線延長上からワ−ク載置部のワ−クとの接触部まで垂直 に降ろした距離が、ワ−ク１の半径と一致するように、ワ−ク載置部７の高さを 、調節ねじ１５で調整して、固定棒センタ−にワ−クセンタ−を合わせることが できる。また、予めワ−クの径を測っておいて、治具を固定棒に取り付け前に、 ワ−ク載置部の高さを調整してもよい。In the second invention, for example, as shown in FIG. 3, a jig is fixed to the fixed rod of the outer diameter grinding machine, and the work of the work placing section is extended from the extension of the center line of the fixed rod. Adjust the height of the work mounting part 7 with the adjusting screw 15 so that the distance vertically lowered to the contact part with the work matches the radius of the work 1 and adjust it to the center of the fixed rod. The work center can be adjusted. Alternatively, the diameter of the work may be measured in advance, and the height of the work mounting portion may be adjusted before the jig is attached to the fixed rod.
【００１４】 第３の考案は、外径研削機の固定棒５に治具を固定し、ワ−クを載せると、た とえば、図１又は図２に示したように、連結部１４上のワ−ク載置部７の表面は 、Ｖ字型又は弧状型の受け７ａで構成されているから、受けの斜面又は弧状面に 沿って、ワ−クが安定し、固定棒５（図４参照）と平行になる。A third invention is that a jig is fixed to a fixing rod 5 of an outer diameter grinding machine, and a work is put on the fixing rod 5. For example, as shown in FIG. 1 or FIG. Since the surface of the work placing portion 7 of the above is constituted by the V-shaped or arcuate receiver 7a, the work is stabilized along the slope or arcuate surface of the receiver, and the fixing rod 5 (Fig. (See 4).
【００１５】 第４の考案では、たとえば、図６及び図７に示したように、治具を、外径研削 機の両端の固定棒５、５´に、それぞれのクランプ部６、６´で固定して用いる 。長尺のワ−クを加工する際に用いられ、重いワ−クでも治具は両端の固定棒５ 、５´に支えられるから平行度を維持することができる。なお両端の固定棒５、 ５´でワ−クを挟持する際には、クランプ部がスライドして固定棒の動きに追従 する。In the fourth invention, for example, as shown in FIG. 6 and FIG. 7, the jig is attached to the fixing rods 5 and 5 ′ at both ends of the outer diameter grinding machine by the respective clamp portions 6 and 6 ′. Use fixedly. It is used when processing a long work, and even with a heavy work, the jig is supported by the fixing rods 5 and 5'at both ends, so that the parallelism can be maintained. When the work is clamped by the fixed rods 5 and 5'at both ends, the clamp part slides to follow the movement of the fixed rods.
【００１６】 第５及び第６の考案は、たとえば、図６及び図７に示したように、ワ−ク載置 部がスライドできるように構成されているから、外径研削機の固定棒５に治具を 固定して、ワ−ク１の長さ方向の中心にワ−ク載置部７を適宣スライドさせるこ とで、ワ−ク１を最も安定したところで支持するようになる。In the fifth and sixth inventions, for example, as shown in FIGS. 6 and 7, the work mounting portion is configured to be slidable, and therefore, the fixed rod 5 of the outer diameter grinding machine is used. By fixing the jig to the work 1 and appropriately sliding the work placing portion 7 at the center of the work 1 in the longitudinal direction, the work 1 is supported at the most stable position.
【００１７】 第７の考案は、たとえば、図６乃至図８に例示した両端クランプの治具で説明 すれば、外径研削機の両方の固定棒５、５´に治具を取付けて、ワ−ク載置部７ にワ−ク１を載せ、固定棒５、５´同士でワ−ク１を挟み固定する。ここで、連 結部１４は固定棒５、５´に平行な凸部１７を有し、またクランプ部６、６´と ワ−ク載置部７との底面には、この凸部に摺動自在に噛み合う凹部１８が形成さ れているから、クランプ部とワ−ク載置部は外径研削機の固定棒５と平行に摺動 させることができる。固定棒５の移動とともにクランプ部６もスム−ズにスライ ドしてワ−ク１を固定する。The seventh invention will be described, for example, with a jig for clamping both ends illustrated in FIGS. 6 to 8, by attaching the jig to both the fixing rods 5 and 5 ′ of the outer diameter grinder, and -Place the work 1 on the work placing portion 7, and fix the work 1 by sandwiching the work 1 between the fixing rods 5 and 5 '. Here, the connecting portion 14 has a convex portion 17 parallel to the fixing rods 5 and 5 ', and the bottom surfaces of the clamp portions 6 and 6'and the work placing portion 7 are slid on the convex portions. Since the concave portion 18 that is movably engaged is formed, the clamp portion and the work mounting portion can be slid in parallel with the fixed rod 5 of the outer diameter grinding machine. As the fixing rod 5 moves, the clamp portion 6 also slides in a smooth manner to fix the work 1.

実施例について図面を参照して説明する。 Examples will be described with reference to the drawings.
【００１９】 実施例１ 図１は、第１又は第３の考案治具の一実施例を示す斜視図である。連結部１４ の一端側にクランプ部６が設けられている。クランプ部６はさらに固定クランプ １２、可動クランプ１１、固定クランプと可動クランプとを片側で軸支するピン １０及び、両クランプを締めつけるクランプ固定つまみ１３より成る。可動クラ ンプ１１はピン１０を軸として開閉できる。連結部１４の他端側には、ワ−クを 載せるためのワ−ク載置部７が設けてあり、受け７ａがＶ字型に形成されている 。Embodiment 1 FIG. 1 is a perspective view showing an embodiment of the first or third invention jig. The clamp portion 6 is provided on one end side of the connecting portion 14. The clamp portion 6 further includes a fixed clamp 12, a movable clamp 11, a pin 10 that pivotally supports the fixed clamp and the movable clamp on one side, and a clamp fixing knob 13 that tightens both clamps. The movable clamp 11 can be opened and closed around the pin 10. On the other end side of the connecting portion 14, a work mounting portion 7 for mounting a work is provided, and a receiver 7a is formed in a V shape.
【００２０】 本考案治具を外径研削機に取り付けるに当り、まず図４に示したように固定棒 ５にクランプ部６で固定する。クランプ部の固定クランプ１２と可動クランプ１ １内側は、この固定棒５の外形に沿うように凹状に形成されており、クランプ固 定つまみ１３を締め付けることで強く挟持する。次にＶ字形の受け７ａが形成さ れたワ−ク載置部７にワ−クを載せると、図５に示したように、ワ−ク径に応じ て固定棒５のセンタ−にワ−クセンタ−が一致するようワ−ク載置部の位置が設 定されているから、自ずとセンタ−合わせが完了する。続いて固定棒５´をワ− ク端面へ当接させ、押圧、把持すると外径研削機へのワ−クセットが完了する。 最後に治具を取外した。本実施例では、ワ−ク外径１５０ｍｍ対応の専用治具を 用いたが、ワ−ク長さは４００ｍｍのものに適用した。When the jig of the present invention is attached to the outer diameter grinding machine, first, as shown in FIG. 4, it is fixed to the fixing rod 5 by the clamp portion 6. The fixed clamp 12 and the inner side of the movable clamp 11 of the clamp portion are formed in a concave shape so as to follow the outer shape of the fixed rod 5, and the clamp fixing knob 13 is clamped to firmly clamp it. Next, when the work is placed on the work placing portion 7 on which the V-shaped receiver 7a is formed, as shown in FIG. 5, the work is placed on the center of the fixing rod 5 according to the work diameter. -Since the position of the work placing part is set so that the center of the work is aligned, the centering is naturally completed. Subsequently, the fixed rod 5'is brought into contact with the work end surface, pressed and gripped, and the work setting for the outer diameter grinding machine is completed. Finally, the jig was removed. In this embodiment, a dedicated jig corresponding to a work outer diameter of 150 mm was used, but the work length was 400 mm.
【００２１】 ２００本のワ−クで実施してみたがセンタ−のずれは０．５ｍｍ以内で、ワ− ク端面を結ぶ軸線の両固定棒センタ−を結ぶ線に対するずれは１．２５／１００ ０以内であった。治具取付けからワ−ク固定、治具取外しまでの一連の作業には 未熟練者１名で１本当り平均４０秒を要した。Although the work was carried out with 200 works, the deviation of the center was within 0.5 mm, and the deviation of the axis connecting the end faces of the work with respect to the line connecting the two fixing rod centers was 1.25 / 100. It was within 0. It took an average of 40 seconds for one unskilled person to perform a series of operations from jig attachment to work fixing and jig removal.
【００２２】 因に、図９に示した従来方式によれば、熟練者２名で１本当り平均８分かかっ た。Incidentally, according to the conventional method shown in FIG. 9, it took an average of 8 minutes for each of two skilled workers.
【００２３】 実施例２ 図３は、第２の考案治具の一実施例を示す縦断面図である。この治具は、実施 例１における治具の受け部７を上下動可能に構成し、その高さを調節ねじ１５に より行なう。調節ねじ１５は、連結部１４を底部より貫通して受け部７内で螺止 される。なお、調節ねじ１５は、図３では表れていないが、奥行き方向にさらに ２本あり、合計４本が設けられている。 治具を固定棒にセットする前に、ワ−クの径を予め測っておき、ワ−クを載置部 に載せたときにワ−クのセンタ−と固定棒のセンタ−とが丁度一致する位置にく るよう、載置部の高さを調節しておく。以下は、実施例１と同様に行った。ただ 、本実施例においては、最初ワ−ク径１００ｍｍのものを、続いて１２５ｍｍ、 １５０ｍｍと、それぞれ載置部の位置を調節して２０本ずつを処理した。なお、 ワ−ク長さはいずれも４００ｍｍのものに適用した。 治具取付けから、ワ−ク固定取外しまでの時間を１本当りに平均して、未熟練者 １名で２分要した。従来の方法では、熟練者２名で８分かかる。Embodiment 2 FIG. 3 is a vertical cross-sectional view showing an embodiment of the second inventive jig. In this jig, the receiving portion 7 of the jig in the first embodiment is configured to be movable up and down, and its height is adjusted by the adjusting screw 15. The adjusting screw 15 penetrates the connecting portion 14 from the bottom and is screwed in the receiving portion 7. Although not shown in FIG. 3, there are two adjustment screws 15 in the depth direction, and a total of four adjustment screws 15 are provided. Before setting the jig on the fixed rod, measure the diameter of the work in advance, and when the work is placed on the placing part, the center of the work and the center of the fixed rod are exactly the same. Adjust the height of the platform so that it is in the desired position. The subsequent steps were performed in the same manner as in Example 1. However, in the present example, 20 pieces each were treated by first adjusting the position of the mounting portion to a work diameter of 100 mm, and then to 125 mm and 150 mm. The work length was 400 mm. The time from jig attachment to work fixing / removal was averaged per wire, and one unskilled person required 2 minutes. With the conventional method, it takes 8 minutes for two skilled persons.
【００２４】 実施例３ 図６は、第４乃至第７の考案治具の一実施例の使用状態を示す斜視図である。 連結部１４の両端には、クランプ部６、６´を設けられ、実施例１同様に固定ク ランプ１２、１２´と可動クランプ１１、１１´を有している。さらに、クラン プ部底部には、連結部上をスライドできるように、連結部長さ方向に設けられた 凸部１７及び凹部１６に摺動自在に噛み合う、凹部及び凸部が設けられている（ 図８参照）。すなわち、凸部についてはレ−ルの働きをしている。 この治具を実施例１と同様な要領で、外径研削機の両方の固定棒５、５´それぞ れに、固定クランプ部１２、１２´と、可動クランプ部１１、１１´で挟み込み 、クランプ固定つまみ１３、１３´により固定し、ワ−ク載置部７にワ−ク１を 載せ、両側固定棒５、５´により、把持した（図７参照）。把持する際には、固 定棒のいずれか一方または両方ともが、ワ−ク側へと移動する必要があるが、前 記のとおり、クランプ部が連結部上をスライドするから、とくに問題はなかった 。Embodiment 3 FIG. 6 is a perspective view showing a usage state of an embodiment of the fourth to seventh invention jigs. Clamps 6 and 6'are provided at both ends of the connecting portion 14, and have fixed clamps 12 and 12 'and movable clamps 11 and 11' as in the first embodiment. Further, the bottom portion of the clamp portion is provided with a concave portion and a convex portion that slidably mesh with the convex portion 17 and the concave portion 16 provided in the connecting portion length direction so that the connecting portion can slide on the connecting portion (FIG. 8). That is, the convex portion functions as a rail. In the same manner as in Example 1, the jig is sandwiched between the fixed clamp parts 12, 12 'and the movable clamp parts 11, 11' on both the fixed rods 5, 5'of the outer diameter grinding machine, The work was fixed by the clamp fixing knobs 13 and 13 ', the work 1 was placed on the work placing portion 7, and was gripped by the both-side fixing rods 5 and 5' (see FIG. 7). When gripping, either one or both of the fixed rods must move to the work side, but as described above, the clamp part slides on the connecting part, so there is no particular problem. I didn't.
【００２５】 ワ−ク１を固定したらクランプ固定つまみ１３、１３´を解除し、可動クラン プ部１１、１１´を外して、治具だけ取り出す。After fixing the work 1, the clamp fixing knobs 13 and 13 'are released, the movable clamp portions 11 and 11' are removed, and only the jig is taken out.
【００２６】 本実施例では、ワ−ク外径１５０ｍｍ対応の専用治具を用いたが、ワ−ク長さ は１０００ｍｍのものに適用した。In this embodiment, a dedicated jig compatible with a work outer diameter of 150 mm was used, but the work length was 1000 mm.
【００２７】 １００本のワ−クで実施してみたがセンタ−のずれは０．５ｍｍ以内で、ワ− ク端面を結ぶ軸線の両固定棒センタ−を結ぶ線からのずれは１．２５／１０００ 以内であった。治具取付けからワ−ク固定、治具取外しまでの一連の作業には未 熟練者２名で１本当り平均２分を要した。[0027] I tried using 100 works, but the deviation of the center was within 0.5 mm, and the deviation of the axis connecting the end faces of the work from the line connecting the centers of both fixed rods was 1.25 / It was within 1000. A series of operations from jig attachment to work fixing and jig removal required an average of 2 minutes per tool by two unskilled personnel.
【００２８】 因に、図９に示した従来方式によれば、熟練者３名で１本当り平均１２分かか った。本考案はまた、外径研削機にとらわれず、他の機器において、円柱系ワ− クの両端を挟み込む装置の芯だしする場合に応用出来る。By the way, according to the conventional method shown in FIG. 9, it took an average of 12 minutes for three trainees. The present invention is also not limited to the outer diameter grinding machine, and can be applied to the centering of a device that sandwiches both ends of a cylindrical work in other devices.
【００２９】 またワ−クは、半導体インゴットでもよい。The work may be a semiconductor ingot.
【００３０】 その他、本考案の何種類かの治具により、ワ−ク直径５０ｍｍ〜２００ｍｍで 、ワ−ク長さ２０ｍｍ〜２０００ｍｍまで、ほとんどに対応できる。In addition, by using several kinds of jigs of the present invention, a work diameter of 50 mm to 200 mm and a work length of 20 mm to 2000 mm can be mostly applied.
【００３１】[0031]
本考案の治具によれば、治具を外径研削機の固定棒に取り付け、あとはワ−ク を治具のワ−ク載置部にのせるだけで、外径研削機の固定棒センタ−とワ−クの センタ−とが一致する。したがって、従来のように熟練者でなければできなかっ たセンタ−合わせが、未熟練者でも可能になるし、時間も１／１２〜１／６へと 短縮されて、生産性に寄与する。 According to the jig of the present invention, the jig is attached to the fixed rod of the outer diameter grinding machine, and then the work is simply placed on the work mounting portion of the jig. The center and the center of the work match. Therefore, it is possible for an unskilled person to perform centering, which was conventionally only possible for an expert person, and the time is shortened to 1/12 to 1/6, which contributes to productivity.
【００３２】 ワ−ク載置部の高さ調節ねじのないものは、ワ−クの直径に対応した専用のも のを用いることになるが、研削すべきワ−クは通常一定規格で流れているから、 特殊な場合を除いて不便はない。If the work mounting part does not have a height adjusting screw, a dedicated work corresponding to the diameter of the work is used, but the work to be ground normally flows according to a certain standard. Therefore, there is no inconvenience except in special cases.
【００３３】 載置部がスライドできるものは、ワ−クの中央に載置部を位置させることで、 安定して支えることができることから、長尺のワ−クに用いて便利である。The slideable mounting portion can be stably supported by positioning the mounting portion at the center of the work, and is therefore convenient for use in a long work.
【００３４】 また、連結部の両端にスライド可能なクランプ部を有したものは、治具が安定 して支持されることから、さらに長尺のワ−クをセットする際便利である。固定 棒でワ−クを把持するときは、クランプ部がスライドして追従するから、もちろ ん短尺のワ−クにも用いることができる。Further, the one having slidable clamp portions at both ends of the connecting portion is convenient for setting a longer work since the jig is stably supported. When gripping the work with the fixing rod, the clamp part slides and follows, so it can be used for short work as well.
【００３５】 以上のことから、本考案によれば、従来のようにとくに熟練者を必要すること なく、短時間でワ−クのセンタ−合わせが可能になり、しかも、センタ−からの ずれは０．５ｍｍ以下、ワ−クの軸線のずれは１．２５／１０００以下と実用上 全く問題のない精度でセットができるようになる。当然従来のようにワ−クが、 落下して破損したり、作業者が負傷するような危険もない。From the above, according to the present invention, it is possible to center the work in a short time without the need for a skilled person as in the prior art, and the deviation from the center can be achieved. The work axis can be set with accuracy of 0.5 mm or less and the work axis line deviation of 1.25 / 1000 or less. Of course, there is no danger that the work will fall and be damaged or the worker will be injured as in the past.
