Abstract

PROBLEM TO BE SOLVED: To provide a means capable of checking a rotating state of an object to be measured, using a simple structure in a rotation apparatus used to measure displacements, such as height and like over the entire circumference.SOLUTION: A rotation checking mechanism is provided, which checks the rotation of a weight mounted on the upper surface of a rotation object being an object to be measured in the rotation apparatus used to measure the displacement, such as the height and the like, over the entire circumference, through a passing detection object disposed at the weight. The rotation checking mechanism is characterized in that the weight is in a shape capable of measuring a displacement of a portion to be measured of the rotation object along with the rotation without covering the portion to be measured, and is out of contact with a mechanism which torques the rotation object.

Description

本発明は、回転対象を回転させる装置において、回転対象の回転を確認するための機構に関する。   The present invention relates to a mechanism for confirming the rotation of a rotating object in an apparatus for rotating the rotating object.

軸受けの内輪や外輪などの筒状物において、孔に垂直な２面間の距離を測定するには、例えば、図９や図１０に示すように、平板２０１の上に測定対象である筒状物２０２を孔が垂直方向になるように置き、筒状物の上に高さ測定器の測定子２０３を接触させて測定する（特許文献１参照）。
このとき、筒状物には、例えば、図９に示すように駆動ローラ２０４とアイドルローラ２０５の挟み込みにより回転力を与えることができる。また、例えば、図１０に示すように、筒状物を上から押さえ込みながら把持する把持部２０６の回転力により、筒状物を回転させることもできる。このように、測定対象物である筒状物を回転させることで、筒状物の孔に垂直な２面間の距離すなわち筒状物の高さを全周にわたって測定することができる。 In order to measure the distance between two surfaces perpendicular to the hole in a cylindrical object such as an inner ring or an outer ring of a bearing, for example, as shown in FIG. 9 or FIG. The object 202 is placed so that the hole is in the vertical direction, and the measuring element 203 of the height measuring instrument is brought into contact with the cylindrical object for measurement (see Patent Document 1).
At this time, for example, as shown in FIG. 9, a rotational force can be applied to the cylindrical object by sandwiching the driving roller 204 and the idle roller 205. Further, for example, as shown in FIG. 10, the cylindrical object can be rotated by the rotational force of the grip portion 206 that holds the cylindrical object while pressing it from above. Thus, by rotating the cylindrical object which is a measurement object, the distance between two surfaces perpendicular to the hole of the cylindrical object, that is, the height of the cylindrical object can be measured over the entire circumference.

特願２００９−１２５５７５ 回転装置Patent application 2009-125575 Rotating device

図９や図１０において、仮にローラが空転した場合や把持部が空転した場合、測定対象の筒状物に接触させる測定子は同じ場所を計測することになるが、測定対象物の形状が同心円の対称形状であれば、回転しているのか空転しているのかの判断が容易でない問題点がある。
このため、例えば、図１１に示すように、回転を検知するためのローラ２０７を設け、測定対象物に接触さて回転を検出する方法や、図１２に示すように、測定対象物を載置する台を回転可能な構造とし、回転可能台に回転を検知するセンサ２０８を設ける方法を考案することができる。しかしながら、高精度での高さ測定の際に、検知ローラの押し当てによる測定対象物の浮き上がりを抑える工夫や、回転可能台の回転による面振れを抑える工夫が必要となり、構造が複雑となる欠点がある。
すなわち、本発明の目的は、測定対象が回転していることを簡易な構造で確認できる手段を提供することにある。 9 and 10, if the roller is idle or the gripping part is idle, the measuring element that contacts the cylindrical object to be measured measures the same place, but the shape of the measuring object is concentric. If it is a symmetrical shape, there is a problem that it is not easy to determine whether it is rotating or idling.
For this reason, for example, as shown in FIG. 11, a roller 207 for detecting rotation is provided, and a method of detecting rotation by contacting the measurement object or a measurement object as shown in FIG. It is possible to devise a method in which the base is configured to be rotatable and the sensor 208 for detecting the rotation is provided on the rotatable base. However, when measuring the height with high accuracy, it is necessary to devise measures to suppress the lifting of the measurement object due to the pressing of the detection roller and to suppress the surface runout due to the rotation of the rotatable base, which makes the structure complicated. There is.
That is, an object of the present invention is to provide means for confirming that a measurement object is rotating with a simple structure.

第１の観点では、本発明は、測定対象である回転対象物の上面に載置されるおもりの回転を、該おもりに備え付けられた検知対象部の通過により確認する回転確認機構であり、上記おもりは、上記回転対象物の被測定部位を覆わず、回転とともに該被測定部位の変位を測定することが可能な形状であり、前記回転対象物に回転力を与える機構と接触しないことを特徴とする回転確認機構を提供する。
上記第１の観点による回転確認機構では、例えば、図１に示す構成とすることができる。図１は、測定対象である回転対象物２０２は円柱形状をしており、平板２０１の上に円柱の軸方向が縦向きになるように載置している。回転対象物２０２は、上面に被測定部位２０２ａがあり、平板２０１と被測定部位２０２ａとの距離を計測すべく、高さ測定器の測定子２０３が被測定部位２０２ａに接している。ここで、駆動ローラ２０４にて回転対象物２０２を回転させることにより、全周にわたった被測定部位２０２ａの測定を行うことができる。なお、図中２０５はアイドルローラである。このとき、回転対象物２０２の上面に、検知対象部として出っ張り１０１を設けたおもり１００を載置して、検知対象部１０１が検知センサ２０８の前を通過することを検出することで、回転対象物２０２が回転していることを確認することができる。このとき、高さ測定器の測定子２０３は、全周にわたって測定可能とするために回転位置に関わらず常に被測定部位２０２ａと接する関係である必要がある。このため、おもり１００は、測定子２０３の測定の邪魔にならないように、被測定部位２０２ａを覆わない形状とする。また、おもり１００は、測定子２０３に接触しないとともに、駆動ローラ２０４などの回転力を与える機構と接触しない構造とすることで、おもり１００の存在により測定値が変化することを極力減らすことができる。
なお、おもり１００の材質や重さは、おもり１００が回転対象物２０２に載置して、回転により位置ずれをおこさないものであれば、軽いものや、ナイロンやウレタンなどの金属以外のものであっても良い。また、おもり１００に備わる検知対象部は、図１に示す突起状のものに限定するものではなく、例えば、スリットの彫刻や、フォトセンサで検出できるペイントなどの標識であっても良い。検出方法についても、非接触式であれば限定するものではなく、例えば、金属や磁気の接近を探知する近接センサや光の反射率の変化を感知するフォトセンサを用いることができる。また、検知対象部の数は、１つであっても良いし、複数であっても良く、例えば、決められた時間内に決められた回数の検知ができれば周回できたと判断すれば良い。
また、図１では被測定部位が回転対象物の上面に位置していたが、例えば、側面に位置して測定子を横から当てる形態であっても良く、測定可能な構造であれば測定形態を限定するものではなく、おもり形状も限定するものではない。また、図１では、回転対象物の形状が円柱形状を示したが、略円柱形状や略円筒形状など、平板上にて回転可能な形状かつ、おもりを載置できる形状であれば限定するものではない。例えば、略円筒形状のように真ん中に窪みまたは孔を有する形状であれば、その窪みまたは孔を利用して例えば図１０に示すように回転力を与えることで、回転対象物の外周の形状が突起を有するなどのいびつな形状であっても実現できる。このとき、おもりの中心には、回転力を回転対象物に与える機構と接しない孔を設けることで本発明を実現できる。
本発明は、回転対象物におもりを載置する非常に簡単な構成であるため、回転機構や測定子との接触をさけたおもりの形状とするだけで実現容易であり、非常に有用である。また、おもりは、回転対象物に回転方向に対して平均的に荷重がかかる形状とするとともに、回転を妨げない程度に重くすることで回転対象物が平板から浮き上がることを防ぐことにつながる利点がある。 In a first aspect, the present invention is a rotation confirmation mechanism that confirms the rotation of a weight placed on the upper surface of a rotating object that is a measurement object by passing through a detection target unit provided on the weight, The weight does not cover the part to be measured of the rotating object, has a shape capable of measuring the displacement of the part to be measured as it rotates, and does not come into contact with a mechanism that applies a rotational force to the rotating object. A rotation confirmation mechanism is provided.
The rotation confirmation mechanism according to the first aspect can be configured as shown in FIG. 1, for example. In FIG. 1, a rotating object 202 that is a measurement object has a cylindrical shape, and is placed on a flat plate 201 so that the axial direction of the cylinder is vertical. The rotating object 202 has a measurement site 202a on the upper surface, and a measuring element 203 of a height measuring instrument is in contact with the measurement site 202a in order to measure the distance between the flat plate 201 and the measurement site 202a. Here, by rotating the rotating object 202 by the driving roller 204, the measurement site 202a can be measured over the entire circumference. In the figure, reference numeral 205 denotes an idle roller. At this time, by placing the weight 100 provided with the protrusion 101 as the detection target portion on the upper surface of the rotation target 202 and detecting that the detection target portion 101 passes in front of the detection sensor 208, the rotation target is detected. It can be confirmed that the object 202 is rotating. At this time, the measuring element 203 of the height measuring device needs to be in contact with the part to be measured 202a at all times regardless of the rotational position in order to enable measurement over the entire circumference. For this reason, the weight 100 has a shape that does not cover the portion to be measured 202a so as not to interfere with the measurement of the measuring element 203. In addition, since the weight 100 does not contact the measuring element 203 and does not contact a mechanism that applies a rotational force such as the driving roller 204, the change in the measurement value due to the presence of the weight 100 can be reduced as much as possible. .
The material and weight of the weight 100 may be light or other than metals such as nylon and urethane, as long as the weight 100 is placed on the rotating object 202 and does not cause displacement. There may be. Further, the detection target portion provided in the weight 100 is not limited to the protrusion-shaped portion shown in FIG. 1, and may be a sign such as a slit engraving or a paint that can be detected by a photosensor. The detection method is not limited as long as it is a non-contact type. For example, a proximity sensor that detects the approach of metal or magnetism or a photosensor that detects a change in the reflectance of light can be used. Further, the number of detection target portions may be one or plural, and for example, if the detection can be performed a predetermined number of times within a predetermined time, it may be determined that the circuit has been circulated.
Further, in FIG. 1, the measurement site is located on the upper surface of the rotating object. However, for example, the measurement site may be located on the side surface and the probe is applied from the side. The weight shape is not limited. In FIG. 1, the shape of the object to be rotated has a columnar shape, but is limited to a shape that can be rotated on a flat plate such as a substantially columnar shape or a substantially cylindrical shape and can place a weight. is not. For example, if the shape has a recess or hole in the middle like a substantially cylindrical shape, the outer periphery shape of the rotating object can be obtained by applying a rotational force as shown in FIG. 10 using the recess or hole, for example. Even an irregular shape such as having a protrusion can be realized. At this time, the present invention can be realized by providing a hole that does not contact the mechanism that applies the rotational force to the rotating object at the center of the weight.
Since the present invention has a very simple configuration in which a weight is placed on a rotating object, it can be easily realized simply by making the shape of a weight avoiding contact with a rotating mechanism or a measuring element, and is very useful. . In addition, the weight has an advantage that prevents the rotating object from being lifted off the flat plate by making the rotating object have an average load on the rotation direction and making it heavy enough not to interfere with the rotation. is there.

第２の観点では、本発明は、第１の観点による回転確認機構において、前記回転対象物の上面に孔または窪みが存在し、前記おもりが該孔または該窪みの一部または全部と外接する形状であることを特徴とする回転確認機構を提供する。
上記第２の観点による回転確認機構では、例えば、図２に示す構成とすることができる。図２は、回転対象物２０２とおもり１００との位置関係を垂直断面にて模擬した図である。おもり１００の外壁が回転対象物２０２の孔による内壁２０２ｂに接することでおもり１００が回転対象物２０２に載置されている。このとき、内すぼみに傾斜している内壁２０２ｂは、真上からみたときに視認できることにより、広義に解釈して上面に含まれるとする。
また、図３に示すように、内壁２０２ｂをガイドとして回転対象物２０２の上面におもり１００を載置することもできる。このように、回転対象物の孔または窪みの内壁を利用することで、おもりの載置における位置決めを行うことができ、センサ２０８と検知対象部１０１との間隔を測定許容範囲に保つことができる。 In a second aspect, the present invention provides the rotation confirmation mechanism according to the first aspect, wherein a hole or a depression is present on the upper surface of the rotating object, and the weight circumscribes a part or all of the hole or the depression. Provided is a rotation confirmation mechanism having a shape.
The rotation confirmation mechanism according to the second aspect can be configured as shown in FIG. 2, for example. FIG. 2 is a diagram simulating the positional relationship between the rotating object 202 and the weight 100 in a vertical section. The weight 100 is placed on the rotating object 202 by the outer wall of the weight 100 contacting the inner wall 202b formed by the hole of the rotating object 202. At this time, it is assumed that the inner wall 202b inclined in the inner recess is visually recognized when viewed from directly above, and is thus interpreted in a broad sense and included in the upper surface.
Further, as shown in FIG. 3, the weight 100 can be placed on the upper surface of the rotating object 202 using the inner wall 202b as a guide. As described above, by using the inner wall of the hole or the hollow of the rotating object, positioning in placing the weight can be performed, and the distance between the sensor 208 and the detection target unit 101 can be kept within the measurement allowable range. .

第３の観点では、本発明は、第１の観点による回転確認機構において、前記おもりが前記回転対象物の外周の一部または全部と外接する形状であることを特徴とする回転確認機構を提供する。
上記第３の観点による回転確認機構では、例えば図４に示す構成とすることができる。図４は、回転対象物２０２とおもり１００との位置関係を垂直断面にて模擬した図である。おもり１００の底面には、回転対象物２０２の外周と接するガイド１０２が設けられ、おもり１００の載置における位置決めを行うことができる。このため、センサ２０８と検知対象部１０１との間隔を測定許容範囲に保つことができる。また、図４に示すように回転対象物２０２の上面に被測定部位が存在する場合、おもり１００の内側に穴１０３を設けることで測定が可能となる。また、回転対象物２０２の側面の変位を測定する場合は、図５に示すように、測定子２０３を回転対象物の側面に接するように設置することから、おもり１００に穴を設けなくても良い。ただし、測定対象物２０２の内壁に回転力を加える機構である場合は、回転力を加える機構を通す穴を図４の１０３のように設ける必要がある。 In a third aspect, the present invention provides the rotation confirmation mechanism according to the first aspect, wherein the weight has a shape circumscribing part or all of the outer periphery of the rotating object. To do.
The rotation confirmation mechanism according to the third aspect can be configured as shown in FIG. 4, for example. FIG. 4 is a diagram simulating the positional relationship between the rotating object 202 and the weight 100 in a vertical section. A guide 102 in contact with the outer periphery of the rotating object 202 is provided on the bottom surface of the weight 100 so that the weight 100 can be positioned when placed. For this reason, the space | interval of the sensor 208 and the detection target part 101 can be kept in a measurement allowable range. Further, as shown in FIG. 4, when the measurement site exists on the upper surface of the rotating object 202, the measurement can be performed by providing the hole 103 inside the weight 100. Further, when measuring the displacement of the side surface of the rotating object 202, as shown in FIG. 5, the measuring element 203 is installed in contact with the side surface of the rotating object, so that there is no need to provide a hole in the weight 100. good. However, in the case of a mechanism that applies a rotational force to the inner wall of the measurement object 202, it is necessary to provide a hole through which the mechanism for applying the rotational force passes as indicated by 103 in FIG.

第４の観点では、本発明は、第１〜３のいずれかの観点による回転確認機構において、前記おもりは、前記回転対象物の回転軸方向に、前記回転対象物を回転させるための回転機構を通すための穴を有し、上記回転機構の上昇により該回転機構と接触し、該回転機構とともに上昇することを特徴とする回転確認機構を提供する。
上記第４の観点による回転確認機構では、例えば図６および図７に示す構成とすることができる。図６は、特許文献１の回転装置に本発明の回転確認機構を組み込む位置を示した図であり、図７は、組み込んだときの回転確認機構の垂直断面を模擬して示した図である。図６において、回転対象物２０２は平板２０１に載置され、回転対象物を回転させるための回転機構２０９が下降するとともに回転対象物２０２の内面を把持し、回転機構２０９と回転対象物２０２が平板２０１上にて回転する。このとき、高さ測定子２０３を回転対象物２０２の上面に接触させて、回転対象物２０２の高さを全周にわたって計測する。図６では、回転機構２０９は、コレットチャック形状であり、円板形状の外側に開く爪の上面に円筒形状の割りの入った接合部が形成されている。本発明の回転確認機構は、回転機構２０９の円筒形状部を接触せず通すことができる貫通孔１０３を有したおもり１００を配置し、おもり１００の検知対象部１０１の通過をセンサ２０８にて検知し、回転対象２０２が回転しているかを確認する。図７は、回転対象物２０２が回転する際のおもり１００、回転対象物２０２および回転機構２０９の位置関係を、垂直断面を模した図にて示したものである。なお、図中符号は図６と共通である。回転機構２０９は、回転対象物２０２の内面にてチャック爪を開いて回転対象物２０２を把持し、回転対象物２０２とともに平板２０１上にて回転する。このとき、おもり１００は、回転機構２０９の円板状のチャック爪から浮き上がる形で回転対象物２０２の上面に載置され、回転対象物２０２とともに回転する。このとき、おもり１００の貫通孔１０３は、おもり１００が回転対象物２０２の内壁に部分的に接するためのガイドの遊びよりも大きな余裕を持って、回転機構２０９の円筒形状部分と接触しない径とする。ゆえに、おもり１００は、回転機構２０９と接触することなく、回転対象物２０２とともに回転することができ、高さ測定器の測定子２０３にほとんど影響を与えることなく回転対象物２０２の回転を確認することができる。また、測定終了時は、回転機構２０９が、チャック爪を閉じながら上昇するときに、おもり１００を円板形状部分に受けて上昇するため、新たな機構を追加することなくおもりの載置が自動にて行える利点がある。 In a fourth aspect, the present invention provides the rotation confirmation mechanism according to any one of the first to third aspects, wherein the weight rotates the rotating object in the rotation axis direction of the rotating object. There is provided a rotation confirmation mechanism which has a hole for passing through, is brought into contact with the rotation mechanism when the rotation mechanism is lifted, and is lifted together with the rotation mechanism.
The rotation confirmation mechanism according to the fourth aspect can be configured as shown in FIGS. 6 and 7, for example. FIG. 6 is a diagram showing a position where the rotation confirmation mechanism of the present invention is incorporated into the rotating device of Patent Document 1, and FIG. 7 is a diagram simulating a vertical cross section of the rotation confirmation mechanism when incorporated. . In FIG. 6, the rotating object 202 is placed on the flat plate 201, the rotating mechanism 209 for rotating the rotating object is lowered, and the inner surface of the rotating object 202 is gripped. The rotating mechanism 209 and the rotating object 202 are It rotates on the flat plate 201. At this time, the height measuring element 203 is brought into contact with the upper surface of the rotating object 202, and the height of the rotating object 202 is measured over the entire circumference. In FIG. 6, the rotation mechanism 209 has a collet chuck shape, and a cylindrical split joint is formed on the upper surface of a claw that opens to the outside of the disk shape. In the rotation confirmation mechanism of the present invention, a weight 100 having a through hole 103 through which a cylindrical portion of the rotation mechanism 209 can pass without contact is disposed, and the sensor 208 detects the passage of the weight 100 through the detection target portion 101. Then, it is confirmed whether the rotation target 202 is rotating. FIG. 7 shows the positional relationship among the weight 100, the rotation object 202, and the rotation mechanism 209 when the rotation object 202 rotates, in a diagram simulating a vertical section. The reference numerals in the figure are the same as those in FIG. The rotation mechanism 209 opens the chuck claw on the inner surface of the rotation target object 202 to grip the rotation target object 202, and rotates on the flat plate 201 together with the rotation target object 202. At this time, the weight 100 is placed on the upper surface of the rotating object 202 so as to be lifted from the disk-shaped chuck claw of the rotating mechanism 209 and rotates together with the rotating object 202. At this time, the through hole 103 of the weight 100 has a diameter that does not contact the cylindrical portion of the rotation mechanism 209 with a larger margin than the play of the guide for allowing the weight 100 to partially contact the inner wall of the rotating object 202. To do. Therefore, the weight 100 can rotate with the rotating object 202 without contacting the rotating mechanism 209, and confirms the rotation of the rotating object 202 with little influence on the measuring element 203 of the height measuring instrument. be able to. At the end of the measurement, when the rotating mechanism 209 is lifted while closing the chuck pawl, the weight 100 is received by the disk-shaped portion, and the weight is automatically placed without adding a new mechanism. There is an advantage that can be done.

本発明の回転確認機構を用いれば、回転機構が空転しているかの確認を非常に簡単な機構により容易に実現することができる。また、回転対象物に加える力を、回転軸に対して均一に加えるため、変位測定に与える影響を最小限にすることができる。   If the rotation confirmation mechanism of the present invention is used, confirmation of whether the rotation mechanism is idling can be easily realized by a very simple mechanism. In addition, since the force applied to the rotating object is uniformly applied to the rotation axis, the influence on the displacement measurement can be minimized.
