Description

本発明は、無段変速機用ベルトのエレメントの板厚を測定する測定装置に関する。   The present invention relates to a measuring apparatus for measuring the plate thickness of an element of a continuously variable transmission belt.

無段変速機用ベルトは、金属製板材から打ち抜かれた複数のエレメントが環状に積層され、各エレメントが相互に外れないように無端のリングに組み付けられて構成されている。この種の無段変速機用ベルトを構成するエレメントは、無段変速機のプーリに接するV面を形成する両端縁を備えるボディーと、該ボディーにネックを介して連設されたヘッドとを備えている。   The continuously variable transmission belt is configured such that a plurality of elements punched from a metal plate are stacked in an annular shape, and are assembled to an endless ring so that the elements do not come apart from each other. An element that constitutes a belt for a continuously variable transmission of this type includes a body having both end edges that form a V surface that contacts a pulley of the continuously variable transmission, and a head that is connected to the body via a neck. ing.

ところで、金属製板材から打ち抜かれた前記エレメントは各部の板厚にばらつきが生じているものがある。このような板厚にばらつきを有するエレメントは、環状に積層した際にエレメント同士が密着せず、無段変速機用ベルトの組立て工程において前記リングへの組み付けが困難となる。また、たとえ前記リングに組み付けられたとしても、エレメント同士の間隔がばらついて無段変速機用ベルトによるプーリ間の駆動力伝達効率が低下するといった品質低下を招くおそれがある。   By the way, the element punched from the metal plate material may have variations in the plate thickness of each part. Such elements having variations in plate thickness do not come into close contact with each other when they are laminated in an annular shape, making it difficult to assemble them into the ring in the assembly process of the belt for continuously variable transmission. Further, even if assembled to the ring, there is a possibility that the quality may be deteriorated such that the spacing between the elements varies and the driving force transmission efficiency between the pulleys by the continuously variable transmission belt decreases.

そこで、従来、無段変速機用ベルトを組み立てるに先だって、作業者がマイクロメータを用いて手作業で該エレメントの各部の板厚を測定することが行なわれている。しかし、手作業によるエレメントの測定は、高い測定精度を得るためには作業者の熟練を要し、作業者毎に測定値にバラツキが生じる不都合がある。また、作業者の手作業によるエレメントの板厚測定においては、該エレメントの前記ボディーやヘッドの複数箇所について一箇所ずつ板厚を測定しなければならず、多大な工数及び長時間を要する不都合がある。   Therefore, conventionally, prior to assembling the continuously variable transmission belt, an operator manually measures the plate thickness of each part of the element using a micrometer. However, manual element measurement requires the skill of an operator in order to obtain high measurement accuracy, and there is an inconvenience that measurement values vary from worker to worker. Further, in the measurement of the plate thickness of the element by the operator's manual work, the plate thickness must be measured one by one for a plurality of locations of the body and head of the element. is there.

そこで、エレメントの複数の測定箇所に対して同時に板厚を測定することができる測定装置が知られている(例えば、特許文献1参照)。この種の測定装置においては、エレメントをその両面が上下方向に向かう姿勢に昇降自在に位置決めし、次いで、該位置決めされたエレメントのボディー及びヘッドに予め設定された複数の測定箇所の下面に複数の第1変位センサの測定子を対応させて当接させる。続いて、各第1変位センサの測定子の上方に対向する複数の第2変位センサの測定子を、位置決めされたエレメントのボディー及びヘッドの上面に当接させる。そして、各変位センサの測定子から得られる変位量に基づいて各測定箇所の板厚を測定する。これによって、一度に複数箇所の板厚が測定できるので、作業者がマイクロメータを用いて各測定箇所の板厚を一箇所ずつ測定する場合に比べて、板厚測定を効率良く行なうことができる。   Therefore, a measuring apparatus capable of measuring the plate thickness at a plurality of measurement locations of the element at the same time is known (for example, see Patent Document 1). In this type of measuring device, the element is positioned so that both surfaces thereof can be raised and lowered in the vertical direction, and then a plurality of measurement elements preset on the body and head of the positioned element are placed on the lower surface of a plurality of measurement points. The measuring elements of the first displacement sensor are brought into contact with each other. Subsequently, the measuring elements of the plurality of second displacement sensors facing above the measuring elements of the first displacement sensors are brought into contact with the body of the positioned element and the upper surface of the head. And the plate | board thickness of each measurement location is measured based on the displacement amount obtained from the measuring element of each displacement sensor. As a result, a plurality of plate thicknesses can be measured at a time, so that the plate thickness measurement can be performed more efficiently than when the operator measures the plate thickness of each measurement location one by one using a micrometer. .

ところで、この種のエレメントは、金属製板材から打ち抜かれたときに僅かな曲りが生じることがある。この曲りについては、ヘッドの中央からネックを経てボディーの中央に至る中心線に沿った方向での発生は極めて少ないが、特にヘッドの両側のイヤーの延びる方向やボディーの左右方向(何れも中心線に直交する方向)に比較的大きく発生する。しかもこの曲りはボディーの左右方向への曲り具合とヘッドの両イヤー方向への曲り具合が一定とはならない。   By the way, this kind of element may bend slightly when it is punched from a metal plate. This bending is very rare in the direction along the center line from the center of the head to the center of the body through the neck, but in particular the direction of the ear extension on both sides of the head and the left and right direction of the body (both center line In a direction orthogonal to the above). Moreover, the bending of the body in the left-right direction and the bending of the head in both ear directions are not constant.

更に、この種のエレメントは、金属製板材から打ち抜かれることによって、部分的に僅かに引け(打抜き時に周囲の端縁から引っ張られることにより形成された肉薄となっている窪み)が発生していることがある。このような引けが発生している場合に、先端が半球状或いは円錐状に形成されている測定子を備えた変位センサを採用すると、引けの内部に測定子の先端が入り込んで当接した場合には実際よりも肉薄に測定されてしまい正確な測定結果が得られない。そのため、近年では、先端が平坦面とされた測定子を備えた変位センサを採用し、引けの内部に測定子の先端が入り込むことを回避するようにしている。   Furthermore, this type of element is partially punched by being punched from a metal plate material (thinned recess formed by being pulled from the peripheral edge during punching). Sometimes. When such a shrinkage occurs, if a displacement sensor equipped with a probe having a hemispherical or conical tip is used, the tip of the probe enters and contacts the inside of the retract In this case, the measurement is thinner than the actual measurement, and an accurate measurement result cannot be obtained. For this reason, in recent years, a displacement sensor including a probe having a flat tip is employed to prevent the tip of the probe from entering the interior of the retract.

しかし、先端が平坦面とされた測定子を各測定箇所に同時に当接させると、前述したように曲りによって傾斜する測定箇所においては、測定子の先端がエレメントに均等に当接されず、測定箇所の傾斜角度に応じて両測定子の間隔が実際の板厚より大きく測定され、熟練した作業者による手作業での測定に比べて測定精度が低くなる不都合があった。
特開2001−304847号公報
However, when a probe with a flat tip is brought into contact with each measurement point at the same time, as described above, the tip of the probe is not evenly contacted with the element at the measurement point inclined by bending. The distance between the two measuring elements is measured to be larger than the actual plate thickness in accordance with the inclination angle of the location, and there is a disadvantage that the measurement accuracy is lower than the manual measurement by a skilled worker.
JP 2001-304847 A

かかる不都合を解消して、本発明は、エレメントの曲がりや引けによる窪みの影響を受けることなく高精度に板厚を測定することができ、しかも、エレメントの板厚を効率良く測定することができる無段変速機用ベルトのエレメントの板厚測定装置を提供することを目的とする。   By eliminating such inconvenience, the present invention can measure the plate thickness with high accuracy without being affected by the depression due to bending or shrinkage of the element, and can efficiently measure the plate thickness of the element. An object of the present invention is to provide a plate thickness measuring device for an element of a continuously variable transmission belt.

かかる目的を達成するために、本発明は、無段変速機のプーリに接するV面が左右の側縁に形成されたボディーと、該ボディーにネックを介して連設されたヘッドとを備えるエレメントに予め設定された複数の測定箇所の板厚を測定する無段変速機用ベルトのエレメントの板厚測定装置であって、前記エレメントの各測定箇所を露出させ、且つ、前記ヘッドを上方とし前記ボディーを下方とする起立姿勢にエレメントを保持する保持手段と、該保持手段に保持されたエレメントの前面側と後面側とに位置して互いに対向すると共に該エレメントに当接・離反すべく進退自在に設けられ、該エレメントに当接する側の先端が平坦面とされた一対の測定子と、両測定子をエレメントの前後面に当接させて両測定子の間隔距離からエレメントの板厚寸法を測定する板厚測定手段と、前記保持手段又は両測定子を、該測定子の進退方向に直行する上下左右方向に移動させ、両測定子間にエレメントの各測定箇所を順次位置させる移動手段とを備え、前記保持手段は、エレメントの起立状態が維持可能な間隔であって且つ測定時のエレメントへの両測定子の当接により移動して生じるエレメントの姿勢を許容する間隔を存して対向する一対の支持部材を備えて両支持部材間にエレメントを支持することを特徴とする。   In order to achieve the above object, the present invention provides an element including a body having V-sides that are in contact with pulleys of a continuously variable transmission formed on left and right side edges, and a head connected to the body via a neck. A device for measuring a plate thickness of an element of a continuously variable transmission belt for measuring a plate thickness of a plurality of measurement points set in advance, wherein each measurement point of the element is exposed, and the head is located above A holding means for holding the element in an upright posture with the body facing downward, and the elements held by the holding means are positioned on the front side and the rear side of the element so as to be opposed to each other and to be able to move forward and backward to contact and separate A pair of measuring elements with a flat tip on the side that contacts the element, and the thickness of the element from the distance between the measuring elements by contacting both measuring elements to the front and rear surfaces of the element. The thickness measuring means for measuring the method and the holding means or both measuring elements are moved in the vertical and horizontal directions perpendicular to the advancing / retreating direction of the measuring element, and each measuring point of the element is sequentially positioned between the measuring elements. The holding means has an interval that can maintain the standing state of the element and that allows an attitude of the element that is moved by contact of the two measuring elements to the element during measurement. And a pair of support members opposed to each other, and the element is supported between the two support members.

本発明の板厚測定装置によってエレメントの各測定箇所の板厚を測定するときには、先ず、前記エレメントを前記保持手段に保持させる。該保持手段においては、エレメントは一対の支持部材間に収容され、ヘッドを上方としボディーを下方とする起立姿勢に保持される。   When measuring the plate thickness of each measurement location of the element with the plate thickness measuring device of the present invention, first, the element is held by the holding means. In the holding means, the element is housed between a pair of support members and is held in an upright posture with the head up and the body down.

次いで、前記移動手段によって前記保持部材に保持されたエレメントの各測定箇所のうち何れか一箇所を、両測定子の間に位置させる。そして、当該測定箇所に両測定子を当接させ、前記板厚測定手段によって両測定子の間隔からエレメントの一測定箇所の板厚を測定する。このとき、両測定子のエレメントに当接する側の先端が平坦面とされているので、測定箇所の一部に引けによる窪みが生じていても、窪みの内部に測定子の先端が入り込むことがなく引けの影響を防止して高精度な板厚の測定を行うことができる。   Next, any one of the measurement points of the element held by the holding member by the moving unit is positioned between the two measuring elements. Then, both measuring elements are brought into contact with the measurement location, and the thickness of one measurement location of the element is measured from the distance between the two measuring features by the thickness measuring means. At this time, since the tip of the both contact elements contacting the element is a flat surface, the tip of the measurement element may enter the inside of the recess even if there is a dent due to shrinkage in a part of the measurement location. Therefore, it is possible to measure the thickness with high accuracy by preventing the influence of shrinkage.

更に、両支持部材の間隔は、測定時のエレメントへの両測定子の当接により移動して生じるエレメントの姿勢を許容する間隔とされている。これにより、前記保持手段の支持部材間のエレメントは、両測定子が当接した際の移動が許容される。即ち、エレメントに僅かに曲りが発生している場合には、両測定子がエレメントに当接すると、エレメントが移動して両測定子の先端の平坦面に倣った姿勢となる。この状態で、各測定箇所のうち何れか一箇所に両測定子を当接するので、エレメントに曲りが発生していても、エレメントの曲り分は、エレメントに両測定子の平坦な先端が当接したときに両測定子が当接されていない部分において吸収され、両測定子の平坦な先端を確実にエレメントに当接することができる。これにより、エレメントに曲りが発生していてもその影響を防止して高精度な板厚の測定を行うことができる。   Further, the interval between the two support members is an interval that allows the posture of the element to be generated by the movement of the two contact elements against the element during measurement. As a result, the element between the support members of the holding means is allowed to move when both measuring elements abut. That is, when the element is slightly bent, when both measuring elements come into contact with the element, the element moves so that the posture follows the flat surface at the tip of both measuring elements. In this state, both measuring elements are in contact with any one of the measurement points. Therefore, even if the element is bent, the flat tip of both measuring elements is in contact with the element. Then, it is absorbed in the part where both measuring elements are not in contact, and the flat tips of both measuring elements can be reliably in contact with the element. As a result, even if the element is bent, its influence can be prevented and the plate thickness can be measured with high accuracy.

続いて、両測定子をエレメントから離反させ、前記移動手段によって前記保持部材に保持されたエレメントの各測定箇所のうち他の一箇所を、両測定子の間に位置させる。次いで、当該測定箇所に両測定子を当接させ、前記板厚測定手段によって板厚を測定する。その後、同様にして各測定箇所について一箇所ずつ測定を行う。これによって、エレメントに設定されている全測定箇所を測定することができ、手作業に比べて作業効率を向上させることができる。しかも、前述したように各測定箇所のうちの一箇所ずつの測定によって、一度に複数の測定箇所に各測定子を当接させる場合に比べて、エレメントの曲がりの影響を受けることなく測定精度を向上させることができる。   Subsequently, the two measuring elements are separated from the element, and the other one of the measuring positions of the element held by the holding member by the moving means is positioned between the two measuring elements. Next, both measuring elements are brought into contact with the measurement location, and the plate thickness is measured by the plate thickness measuring means. Thereafter, the measurement is performed for each measurement location in the same manner. As a result, it is possible to measure all measurement points set in the element, and it is possible to improve work efficiency compared to manual work. In addition, as described above, the measurement accuracy can be improved without being affected by the bending of the element, as compared with the case where each measuring element is brought into contact with a plurality of measuring points at a time by measuring each of the measuring points. Can be improved.

When the cylinder 37 shortens the piston rod 36, first, the second sliding member 33 becomes the first sliding member 32. The contact member 41a contacts the stopper 38. At this time, the second measuring element 39 comes into contact with the element 2 to be the measurement reference position of the element 2. When the piston rod 36 is further shortened, the thrust of the cylinder 37 is larger than the urging force of the spring 38 a, so that the spring 38 a is compressed and the first sliding member 32 moves toward the second sliding member 33. Accordingly, the tip of the sensor 34 comes into contact with the measurement reference seat 42.

更にピストンロッド36が短縮すると、第1測定子35がエレメント2に当接し、第2測定子39と共にエレメント2を挟持した状態となる。この位置で、エレメント2は位置決めされて支持部材15,16との隙間が適正に保たれる。更にピストンロッド36が短縮すると、バネ40を圧縮しながらピストンロッド36はシリンダ37の最後端で停止する。このとき、バネ38aの付勢力(固定荷重で弱い)とバネ40の付勢力(調整可変で強い)との差が測定圧となる。これによって、センサー34の測定圧に依存することなくバネ40の付勢力を調整することで、最適な測定圧を選択することができる。センサー35は、その先端が測定基準座42に当接してから、次に第1測定子35がエレメント2に当接して止まるまでのストロークを読み取る。そして、このとき読み取られたセンサー35のストロークと、予めセンサー35により測定した前記ゲージ14a,14bの基準となる厚み寸法との相対的な値からエレメント2の板厚を算出する。   When the piston rod 36 is further shortened, the first measuring element 35 comes into contact with the element 2 and the element 2 is sandwiched together with the second measuring element 39. At this position, the element 2 is positioned and the gap with the support members 15 and 16 is properly maintained. When the piston rod 36 is further shortened, the piston rod 36 stops at the rearmost end of the cylinder 37 while compressing the spring 40. At this time, the difference between the urging force of the spring 38a (weak at a fixed load) and the urging force of the spring 40 (adjustable and strong) becomes the measurement pressure. As a result, the optimum measurement pressure can be selected by adjusting the biasing force of the spring 40 without depending on the measurement pressure of the sensor 34. The sensor 35 reads the stroke from when the tip of the sensor 35 comes into contact with the measurement reference seat 42 until the first measurement piece 35 comes into contact with the element 2 and stops. Then, the plate thickness of the element 2 is calculated from the relative value of the stroke of the sensor 35 read at this time and the thickness dimension serving as a reference of the gauges 14a and 14b measured in advance by the sensor 35.

このようにして板厚測定手段11の測定動作は完了するが、その後、第2摺動部材33が規制部材30aに当接して停止し、第1摺動部材32が図示しない規制部材に当接して停止するまでピストンロッド36を伸長させることにより、即座にエレメント2から両測定子35,39を離反させることができる。この状態で、前記移動手段10によるエレメント2の移動が可能となる。   In this way, the measurement operation of the plate thickness measuring means 11 is completed. Thereafter, the second sliding member 33 comes into contact with the regulating member 30a and stops, and the first sliding member 32 comes into contact with the regulating member (not shown). By extending the piston rod 36 until it stops, both the measuring elements 35 and 39 can be immediately separated from the element 2. In this state, the element 2 can be moved by the moving means 10.

次に、本実施形態の測定装置1によるエレメント2の板厚の測定を説明する。先ず、図1を参照すれば、移動手段10の縦スライドベース25を下降させておき、保持手段9を板厚測定手段11から離反させて、エレメント保持部13を開放させる。そして、保持手段9の各支持部材15,16間に起立状態でエレメント2を載置する。このとき、図4に示すように、エレメント2は各支持部材15,16間において、ボディー3の凹部20,21が載置部材18,19に係合して横方向の移動が規制される。   Next, measurement of the plate thickness of the element 2 by the measuring apparatus 1 of the present embodiment will be described. First, referring to FIG. 1, the vertical slide base 25 of the moving means 10 is lowered, the holding means 9 is separated from the plate thickness measuring means 11, and the element holding portion 13 is opened. Then, the element 2 is placed in a standing state between the support members 15 and 16 of the holding means 9. At this time, as shown in FIG. 4, in the element 2, the concave portions 20 and 21 of the body 3 are engaged with the mounting members 18 and 19 between the support members 15 and 16, and lateral movement is restricted.

次いで、図1に示すように、移動手段10の縦スライドベース25が上昇し、板厚測定手段11の第1測定子35と第2測定子39との間にエレメント2を位置される。続いて、図4及び図5を参照すれば、第1測定子35と第2測定子39とが各測定箇所a〜eに順次当接し、各測定箇所a〜eの板厚寸法が測定される。支持部材15,16の間隔は、測定時のエレメント2への両測定子35,39の当接により移動して生じるエレメントの姿勢を許容する間隔とされている。エレメント2は、このような間隔の支持部材15,16間に支持されていると共に、第1測定子35と第2測定子39とが各測定箇所a〜eの一箇所ずつ挟み込んで当該測定箇所の板厚を測定するので、エレメント2に両測定子35,39の平坦な先端が当接したときには、支持部材15,16間でエレメント2が移動して、両測定子35,39の平坦な先端に倣った姿勢となり、エレメント2の曲り分は両測定子35,39が当接されていない部分において吸収される。これにより、エレメント2に曲がりが生じている場合であっても、両測定子35,39の平坦な先端が確実にエレメント2に当接され、エレメント2の曲がりに影響を受けることなく全ての測定箇所a〜eの板厚を測定することができる。しかも、両測定子35,39の先端が平坦に形成されていることによって、測定箇所a〜eの一部に引けによる窪みが生じていても、窪みの内部に測定子35,39の先端が入り込むことがなく板厚を測定することができる。   Next, as shown in FIG. 1, the vertical slide base 25 of the moving means 10 is raised, and the element 2 is positioned between the first measuring element 35 and the second measuring element 39 of the plate thickness measuring means 11. Next, referring to FIGS. 4 and 5, the first measuring element 35 and the second measuring element 39 are sequentially brought into contact with the measurement points a to e, and the plate thickness dimensions of the measurement points a to e are measured. The The interval between the support members 15 and 16 is an interval that allows the posture of the element that is moved by the contact of the two measuring elements 35 and 39 to the element 2 at the time of measurement. The element 2 is supported between the support members 15 and 16 having such an interval, and the first measuring element 35 and the second measuring element 39 are sandwiched one by one at each measuring position a to e. Therefore, when the flat tips of the two measuring elements 35 and 39 come into contact with the element 2, the element 2 moves between the support members 15 and 16, and the two measuring elements 35 and 39 are flat. The posture follows the tip, and the bent portion of the element 2 is absorbed in the portion where the measuring elements 35 and 39 are not in contact. As a result, even when the element 2 is bent, the flat tips of both the measuring elements 35 and 39 are surely brought into contact with the element 2, and all the measurements are not affected by the bending of the element 2. The plate thickness of the locations a to e can be measured. In addition, since the tips of the measuring elements 35 and 39 are formed flat, even if a dent due to shrinkage occurs in a part of the measurement points a to e, the tips of the measuring elements 35 and 39 are inside the depression. The plate thickness can be measured without entering.

なお、本実施形態においては、大型のエレメント2Lと小型のエレメント2Sとをそれぞれ保持するエレメント保持部13を備えたものを示したが、これに限るものではなく、図示しないが、何れか一方のエレメント2を保持する保持部のみを設けておいてもよい。   In addition, in this embodiment, although the thing provided with the element holding | maintenance part 13 holding each of the large sized element 2L and the small sized element 2S was shown, it is not restricted to this, Although not illustrated, either one is shown. Only a holding portion for holding the element 2 may be provided.
