まず、実施例１における芯出しの対象となる電磁石装置２０について説明する。図３は、本発明の芯出し装置１０を芯出しの対象装置である電磁石装置２０に装着した状態を示す正面図である。電磁石装置２０は中央の空間を取り囲んでそれぞれ９０度ずつ異なる方向を向く４つの電磁石２１が配置され、それぞれの電磁石２１の磁心２３の外側２２は連結されており、磁心２３の中央の空間側の端部２４はかまぼこ状突起（凸曲面、円筒形の側面形状）形状である。   First, the electromagnet device 20 to be centered in Example 1 will be described. FIG. 3 is a front view showing a state in which the centering device 10 of the present invention is mounted on the electromagnet device 20 which is a target device for centering. The electromagnet device 20 includes four electromagnets 21 that surround a central space and face in different directions by 90 degrees, and the outer sides 22 of the magnetic cores 23 of the electromagnets 21 are connected to each other. The end 24 has a semi-cylindrical shape (convex curved surface, cylindrical side shape).

端部２４は電磁石装置２０の中心軸から等距離かつお互いに等角度（隣接する端部となす中心角度が９０度）に配置されており、本発明の芯出し装置１０は、複数（４つ）の突起（かまぼこ状突起の端部）によって規定された空間の中心軸２５の位置を求めるものである。本発明の芯出し装置１０は、図３に示すように、略円筒形の芯出し装置１０の側面の平面部１１を磁心２３の端部２４と合わせることにより、電磁石装置２０の中央の空間部に挿入することができるように構成されている。   The end portions 24 are arranged at the same distance from the central axis of the electromagnet device 20 and at the same angle with each other (the center angle formed with the adjacent end portions is 90 degrees). The position of the central axis 25 of the space defined by the projection (end of the kamaboko-like projection). As shown in FIG. 3, the centering device 10 of the present invention has a central space portion of the electromagnet device 20 by aligning the flat portion 11 on the side surface of the substantially cylindrical centering device 10 with the end portion 24 of the magnetic core 23. It is configured so that it can be inserted into.

図１は、本発明の芯出し装置の構成を示す平面図、側面図、断面図である。なお、図１下方右半分はＡ−Ｂ断面を示している。本発明の芯出し装置１０は、半径が電磁石装置２０の端部２４の突起と中心との最短距離よりも僅かに長い中空の略円筒形であり、外側面にお互いが等角度（９０度）な複数（４）箇所に平面１１が設けられている。この平面１１は、電磁石装置２０の端部２４の突起と対応して、前記中心軸からの距離が前記突起と前記中心軸との最短距離よりも僅かに短い位置（図２のＤ）に、前記突起上における前記中心軸への最短位置（図２のＣ）から前記芯出し装置の中心軸へ下した垂線と垂直に交わるように配置された複数の平面に相当する。   FIG. 1 is a plan view, a side view, and a sectional view showing the configuration of the centering device of the present invention. In addition, the lower right half of FIG. 1 has shown the AB cross section. The centering device 10 of the present invention is a hollow, generally cylindrical shape whose radius is slightly longer than the shortest distance between the projection of the end portion 24 of the electromagnet device 20 and the center, and the outer surface is equiangular (90 degrees). Flat surfaces 11 are provided at a plurality of (4) locations. The flat surface 11 corresponds to the protrusion of the end portion 24 of the electromagnet device 20 at a position where the distance from the central axis is slightly shorter than the shortest distance between the protrusion and the central axis (D in FIG. 2). It corresponds to a plurality of planes arranged so as to intersect perpendicularly to the perpendicular line from the shortest position (C in FIG. 2) to the central axis on the protrusion to the central axis of the centering device.

また、芯出し装置１０の一方の端部（開口部）には、その交点が芯出し装置の中心軸の位置を指示するガイド手段（＝ターゲット）であるワイヤー１３が十字状に張られている。金属製のワイヤーの直径は例えば０．１ｍｍであってもよい。更に、芯出し装置１０の両端部にはワイヤー１３を保護するために透明な樹脂板１５、１７がビス１６によって固着されている。なお、中心軸の位置を指示するワイヤー１３の交点（Ａ）２５が外部から直接見えるようにするために、樹脂板１５、１７の中央部は開口されている。ワイヤー１３は芯出し装置１０の側面に中心軸と平行に設けられた溝１２を通り、反対側の端部にビス１４によって固着されている。   Further, at one end (opening) of the centering device 10, a wire 13, which is a guide means (= target) whose intersection points indicate the position of the center axis of the centering device, is stretched in a cross shape. . The diameter of the metal wire may be, for example, 0.1 mm. Further, transparent resin plates 15 and 17 are fixed to both ends of the centering device 10 with screws 16 in order to protect the wires 13. The central portions of the resin plates 15 and 17 are opened so that the intersection (A) 25 of the wire 13 indicating the position of the central axis can be directly seen from the outside. The wire 13 passes through a groove 12 provided on the side surface of the centering device 10 in parallel with the central axis, and is fixed to the opposite end portion with a screw 14.

芯出し装置１０のワイヤー１３が配置されている端部とは反対側の端部近傍の外側面には、使用者が手で操作し易いように、表面に滑り止めの綾目ローレット加工を施したグリップ部１８が形成されている。   The outer surface in the vicinity of the end opposite to the end where the wire 13 of the centering device 10 is disposed is provided with a non-slip twill knurled surface so that the user can easily operate it by hand. The grip portion 18 is formed.

なお、ワイヤーによる十字のターゲット手段は反対側の端部のみあるいは両端部に設けてもよい。また、。透明な樹脂板１５、１７に中心軸の位置を示すガイド線を描くなど、ワイヤーによる十字以外の指示手段を備えてもよい。   In addition, you may provide the cross-shaped target means by a wire only in the edge part on the opposite side, or both ends. Also,. You may provide instruction | indication means other than the cross by a wire, such as drawing the guide line which shows the position of a central axis in the transparent resin plates 15 and 17. FIG.

図２は、本発明の芯出し装置を使用した芯出し方法を示す説明図である。まず、図２（ａ）に示すように、芯出し対象装置である電磁石装置２０の突起２４と芯出し装置の平面１１とが対面するように、芯出し装置１０を電磁石装置２０の中央の空間内に挿入する。なお、挿入直後の位置や向きは任意である。   FIG. 2 is an explanatory view showing a centering method using the centering apparatus of the present invention. First, as shown in FIG. 2A, the centering device 10 is placed in the center space of the electromagnet device 20 so that the protrusion 24 of the electromagnet device 20 as the centering target device and the flat surface 11 of the centering device face each other. Insert inside. Note that the position and orientation immediately after insertion are arbitrary.

平面１１と中心軸２５の距離ａは、電磁石装置２０の端部２４の突起と中心軸２５との最短距離をｂ、芯出し装置１０の半径をｃとすると、ｃ＞ｂ＞ａとなっている。具体的にはｂが３４ｍｍ程度の場合、ａ＝３３．７ｍｍ、ｃ＝３５ｍｍ程度であってもよい。挿入された芯出し装置１０はある角度範囲（例えば±５度）内でのみ回転可能である。   The distance a between the plane 11 and the central axis 25 is c> b> a, where b is the shortest distance between the protrusion of the end 24 of the electromagnet device 20 and the central axis 25 and c is the radius of the centering device 10. Yes. Specifically, when b is approximately 34 mm, a may be approximately 33.7 mm and c may be approximately 35 mm. The inserted centering device 10 can rotate only within a certain angle range (for example, ± 5 degrees).

次に、芯出し装置１０のグリップ部１８を手でつまみ、中心軸２５を中心として回転するように芯出し装置１０にトルクを加えながら、中心軸２５と垂直な方向に移動させる力を加え、更に、この力の方向を中心軸２５と垂直な面内においてトルクの方向とは逆方向に順次変化させる。   Next, the grip portion 18 of the centering device 10 is pinched by hand and a force for moving the centering device 10 in a direction perpendicular to the center axis 25 is applied while applying torque to the centering device 10 so as to rotate about the center axis 25. Further, the direction of this force is sequentially changed in a direction opposite to the direction of torque in a plane perpendicular to the central axis 25.

即ち、図２において例えばトルクＲを反時計回りに加えながら、中心軸２５と垂直な方向に移動させる力の向きを右Ｓ→下Ｔ→左Ｕ→上Ｖ→右Ｓ→…と時計回りに連続して変化させる。すると、いずれかの突起２４と平面１１との間に隙間がある場合には、芯出し装置１０は中心軸２５と垂直な方向に時計回りに順次移動すると共に、トルクＲがかかっているので前記移動のたびに芯出し装置１０は中心軸２５を中心として反時計回りにわずかに回転する。   That is, in FIG. 2, for example, the torque R is applied in the counterclockwise direction, and the direction of the force to move in the direction perpendicular to the central axis 25 is clockwise as right S → down T → left U → upper V → right S →. Change continuously. Then, when there is a gap between any one of the protrusions 24 and the flat surface 11, the centering device 10 sequentially moves clockwise in the direction perpendicular to the central axis 25 and the torque R is applied. The centering device 10 slightly rotates counterclockwise around the central axis 25 every time it moves.

使用者が中心軸と垂直な方向に移動させる力の向きを右Ｓ→下Ｔ→左Ｕ→上Ｖ→右Ｓ→…と時計回りに変化させていくと、芯出し装置１０は中心軸を中心として少しずつ回転し、この回転に従って突起２４と平面１１との間の隙間が徐々に狭くなり、ついに図２（ｂ）に示すように、全ての隙間がなくなって芯出し装置１０は移動および回転をしなくなる。この状態が芯出し状態であり、使用者が芯出し装置１０から手を離しても芯出し装置１０は摩擦によってこの芯出し状態のまま保持される。なお、取り外す場合には芯出し装置１０に反対方向にトルクをかければ隙間が生じ、容易に引き抜くことができる。   When the direction of the force that the user moves in the direction perpendicular to the center axis is changed clockwise from right S → down T → left U → upper V → right S →..., The centering device 10 moves the center axis. As the center rotates little by little, the gap between the projection 24 and the flat surface 11 gradually narrows according to this rotation. Finally, as shown in FIG. Stops spinning. This state is a centering state, and the centering device 10 is maintained in this centering state by friction even if the user releases his hand from the centering device 10. When removing the centering device 10, torque can be applied in the opposite direction to create a gap, which can be easily pulled out.

発明者が実験した結果、挿入された芯出し装置１０が任意の初期位置であっても、上記した芯出し操作後には必ず同じ芯出し位置において移動および回転を停止することを確認した。従って、使用者はワイヤー１３の交点によって示される電磁石装置２０の中心軸２５が他の装置や管の中心軸と合うように電磁石装置２０と他の装置の相対位置を容易にかつ高精度に調整することができる。なお、トルクをかける回転方向はどちらでもよい。   As a result of experiments by the inventor, it was confirmed that the movement and rotation are always stopped at the same centering position after the above-described centering operation even if the inserted centering device 10 is at an arbitrary initial position. Therefore, the user can easily and accurately adjust the relative positions of the electromagnet device 20 and the other device so that the central axis 25 of the electromagnet device 20 indicated by the intersection of the wires 13 matches the central axis of the other device or tube. can do. In addition, the rotation direction which applies a torque may be any.

図４は、本発明の第２実施例の芯出し装置の構成を示す平面図である。実施例１においては、電磁石装置２０の磁心の端部２４がかまぼこ状の突起となっている例について説明したが、端部３０が中心軸方向に対して垂直な平面である場合には実施例１の構成では芯出しができない。実施例２は電磁石装置２０の磁心の端部３０が中心軸方向に対して垂直な平面である場合に適合した実施例である。   FIG. 4 is a plan view showing the configuration of the centering device of the second embodiment of the present invention. In the first embodiment, the example in which the end 24 of the magnetic core of the electromagnet device 20 is a semi-cylindrical protrusion has been described. However, when the end 30 is a plane perpendicular to the central axis direction, the embodiment is described. With the configuration of 1, centering cannot be performed. The second embodiment is an embodiment suitable for the case where the end 30 of the magnetic core of the electromagnet device 20 is a plane perpendicular to the central axis direction.

実施例２において実施例１と異なる点は、実施例１における平面１１が実施例２においては突起３２（凸曲面、円筒形の側面形状＝かまぼこ状）となっている点である。図２における実施例では、突起３２は円筒形の側面形状であり、この円筒形の半径は電磁石装置２０の端部３０の平面と中心軸２５との最短距離ｂの数倍程度である。   The second embodiment is different from the first embodiment in that the flat surface 11 in the first embodiment is a protrusion 32 (convex curved surface, cylindrical side surface shape = kamaboko shape) in the second embodiment. In the embodiment shown in FIG. 2, the protrusion 32 has a cylindrical side shape, and the radius of the cylindrical shape is several times the shortest distance b between the plane of the end 30 of the electromagnet device 20 and the central axis 25.

実施例２は、実施例１における磁心端部２４の突起と芯出し装置１０の平面１１の関係を入れ替えたものである。実施例２においても、中心軸に対する端部３０の最短位置は図４の（Ｅ）の位置であり、芯出し装置３１が図４の位置（突起３２を形成する円の中心と中心軸２５を結ぶ線が端部３０の最短位置（Ｅ）を通る位置）にある場合が隙間が最も広く、この位置から芯出し装置３１をいずれかの方向に回転させるに従って隙間が徐々に狭くなる。   In the second embodiment, the relationship between the protrusion of the magnetic core end portion 24 and the flat surface 11 of the centering device 10 in the first embodiment is exchanged. Also in the second embodiment, the shortest position of the end 30 with respect to the central axis is the position shown in FIG. 4E, and the centering device 31 moves the position shown in FIG. 4 (the center of the circle forming the protrusion 32 and the central axis 25). The gap is the widest when the connecting line is at the position passing through the shortest position (E) of the end portion 30. The gap gradually narrows as the centering device 31 is rotated in either direction from this position.

従って、機能的には実施例２は実施例１と同じであり、芯出し方法も実施例１と同じである。なお、実施例１においても、電磁石装置２０の磁心の端部２４のかまぼこ状の突起の半径が大きく、平面に近い場合には、実施例２の構成を採用する必要がある。また、実施例２は断面が正方形のダクトなどの芯出しにも使用可能である。   Therefore, the second embodiment is functionally the same as the first embodiment, and the centering method is the same as the first embodiment. In the first embodiment as well, the configuration of the second embodiment needs to be adopted when the radius of the semi-cylindrical protrusion at the end 24 of the magnetic core of the electromagnet device 20 is large and close to a plane. Further, the second embodiment can be used for centering a duct having a square cross section.

以上、実施例を開示したが、本発明においては以下のような変形例も考えられる。実施例においては芯出し装置の外形は略円筒形で断面が円である例を開示したが、挿入できる空間があれば芯出し装置の外径は断面が正方形の直方体であってもよい。   Although the embodiments have been disclosed above, the following modifications are also conceivable in the present invention. In the embodiment, an example in which the outer shape of the centering device is substantially cylindrical and the cross section is a circle is disclosed. However, the outer diameter of the centering device may be a rectangular parallelepiped as long as there is a space that can be inserted.

実施例においては磁心の端部が４個である電磁石装置を芯出し対象装置としたので平面１１は等角度で４個設ける例を開示したが、平面１１の個数は芯出し対象装置の構成と対応する４以上の任意の個数で本発明を実施可能である。この場合、芯出し装置は正多角柱でもよい。   In the embodiment, an electromagnet device having four magnetic core ends is used as a centering target device. Therefore, an example in which four planes 11 are provided at equal angles is disclosed. However, the number of planes 11 is the same as the configuration of the centering target device. The present invention can be implemented with any corresponding number of four or more. In this case, the centering device may be a regular polygonal column.

本発明の芯出し装置および芯出し方法は中央に空間を有する任意の装置の芯出しに適用できる。   The centering device and the centering method of the present invention can be applied to centering of any device having a space in the center.
