Description

本発明は、被測定物の巾を測定する簡易巾測定装置に関する。 The present invention relates to a simple width measuring device for measuring the width of an object to be measured.

被測定物の巾を測定する簡易巾測定装置としては、例えば、ノギスやマイクロメータがある。 Examples of the simple width measuring device for measuring the width of the object to be measured include a caliper and a micrometer.

図３１は、特許文献１に記載されるノギス１００の平面図である。
例えば、特許文献１に記載されるノギス１００は、ジョウ１１１を備える本尺１１０に、ジョウ１２１を備える第１スライダ１２０が摺動可能に設けられている。また、本尺１１０には第２スライダ１３０が摺動可能に設けられている。第２スライダ１３０は、弾性部材１５０とロック機構１４０を介して第１スライダ１２０に連結されている。ロック機構１４０は、一端が第１スライダ１２０に固定された支点バー１４１と、支点バー１４１の他端に回動可能に保持されるロック片１４５とを有する。ロック片１４５は、第２スライダ１３０に係合可能な係合部１４６と、本尺１１０に形成されたデプスバー収納溝１１３に所定の隙間を空けて収納される係合突起部材１４７を有する。 3 1 is a plan view of a caliper 100 which is described in Patent Document 1.
For example, in a caliper 100 described in Patent Document 1, a first slider 120 including a jaw 121 is slidably provided on a main scale 110 including a jaw 111. Further, a second slider 130 is slidably provided on the main scale 110. The second slider 130 is connected to the first slider 120 via the elastic member 150 and the lock mechanism 140. The lock mechanism 140 includes a fulcrum bar 141 whose one end is fixed to the first slider 120, and a lock piece 145 that is rotatably held at the other end of the fulcrum bar 141. The lock piece 145 includes an engagement portion 146 that can be engaged with the second slider 130, and an engagement protrusion member 147 that is stored in a depth bar storage groove 113 formed in the main scale 110 with a predetermined gap.

ノギス１００は、測定時に、第２スライダ１３０を本尺１１０に沿ってかつジョウ１１１，１２１が狭まる方向へ移動させていくと、第１スライダ１２０も本尺１１０に沿って同方向へ移動されていき、やがて、第１スライダ１２０のジョウ１２１と本尺１１０のジョウ１１１との間で被測定物を挟む。この状態において、第２スライダ１３０をさらに同方向へ移動させようとすると、第１スライダ１２０はそれ以上移動することができないため、弾性部材１５０が圧縮されると共に、第２スライダ１３０が第１スライダ１２０に接近する方向へ移動される。すると、ロック機構１４０のロック片１４５が変位されて係合部１４６と係合突起部材１４７を第２スライダ１３０とデプスバー収納溝１１３に係合させ、第２スライダ１３０の移動をロックする。この状態では、それ以上の力が第２スライダ１３０から第１スライダ１２０へ伝わらないから一定の測定力の下で、メモリや表示値の読み取りができる。 When the caliper 100 moves the second slider 130 along the main scale 110 and in the direction in which the jaws 111 and 121 are narrowed during measurement, the first slider 120 is also moved along the main scale 110 in the same direction. Eventually, the object to be measured is sandwiched between the jaw 121 of the first slider 120 and the jaw 111 of the main scale 110. In this state, if the second slider 130 is further moved in the same direction, the first slider 120 cannot move any further, so that the elastic member 150 is compressed and the second slider 130 is moved to the first slider. It is moved in a direction approaching 120. Then, the locking piece 145 of the locking mechanism 140 is displaced, and the engaging portion 146 and the engaging protrusion member 147 are engaged with the second slider 130 and the depth bar storage groove 113, and the movement of the second slider 130 is locked. In this state, since no further force is transmitted from the second slider 130 to the first slider 120, the memory and the display value can be read under a certain measuring force.

図３２は、特許文献２に記載されるマイクロメータ２００の平面図である。
また例えば、特許文献２に記載されるマイクロメータ２００は、ウォームギア２１９が電動モータ２１５により回転される。電動モータ２１５の回転は、モータエンコーダ２２１により検出されている。電動モータ２１５とモータエンコーダ２２１は、図示しないマイクロプロセッサに接続されている。測定ロッド２３０は、ウォームギア２１９に接合し、ウォームギア２１９の回転に従って駆動されている。エンコーダ２３３は、図示しないマイクロプロセッサに接続し、測定ロッド２３０が１インチ変位する毎にパルスを図示しないマイクロプロセッサに出力する。測定ロッド２３０には、円錐体２３１が設けられている。円錐体２３１は、テストストライク２２８，２２８の間に設けられ、測定ロッド２３０とともに前進することにより、円錐体２３１の変位によりテストストライク２２８，２２８を離間させる。測定ロッド２３０の内部には、ばね２２７が収納され、機械的なエネルギーを蓄積できるようになっている。 3 2 is a plan view of the micrometer 200 which is described in Patent Document 2.
For example, in the micrometer 200 described in Patent Document 2, the worm gear 219 is rotated by the electric motor 215. The rotation of the electric motor 215 is detected by the motor encoder 221. The electric motor 215 and the motor encoder 221 are connected to a microprocessor (not shown). The measuring rod 230 is joined to the worm gear 219 and driven according to the rotation of the worm gear 219. The encoder 233 is connected to a microprocessor (not shown), and outputs a pulse to the microprocessor (not shown) every time the measuring rod 230 is displaced by 1 inch. The measuring rod 230 is provided with a cone 231. The cone 231 is provided between the test strikes 228 and 228, and moves forward with the measuring rod 230, so that the test strikes 228 and 228 are separated by the displacement of the cone 231. A spring 227 is housed inside the measuring rod 230 so that mechanical energy can be stored.

このようなマイクロメータ２００は、電動モータ２１５によりウォームギア２１９が回転すると、測定ロッド２３０が円錐体２３１と共に前進し、テストストライク２２８，２２８を離間させる。テストストライク２２８，２２８が被測定物に接触すると、円錐体２３１及び測定ロッド２３０の前進が停止される。図示しないマイクロプロセッサは、エンコーダ２３３がパルスを出力しなくなったことにより測定ロッド２３０が停止したことを検出するが、さらに電動モータ２１５を所定数回転させる。このとき、電動モータ２１５の回転数は、モータエンコーダ２２１が出力する信号により図示しないマイクロプロセッサに検知されている。 In such a micrometer 200, when the worm gear 219 is rotated by the electric motor 215, the measuring rod 230 moves forward together with the cone 231 and separates the test strikes 228 and 228. When the test strikes 228 and 228 contact the object to be measured, the forward movement of the cone 231 and the measuring rod 230 is stopped. A microprocessor (not shown) detects that the measuring rod 230 has stopped due to the encoder 233 no longer outputting pulses, but further rotates the electric motor 215 a predetermined number of times. At this time, the rotational speed of the electric motor 215 is detected by a microprocessor (not shown) by a signal output from the motor encoder 221.

しかしながら、上記ノギス１００及びマイクロメータ２００は、以下の問題があった。
（１）ノギス１００は、第２スライダ１３０を指で移動させてジョウ１１１，１２１で被測定物を所定圧で挟み込んで測定を行うが、第２スライダ１３０の移動速度が速すぎると、所定圧より大きい圧力で被測定物を挟み込んで誤差を生じる虞がある。そのため、ノギス１００で被測定物を測定する場合には、被測定物を挟み込む圧力を一定にするように、作業者が第２スライダ１３０をゆっくり移動させていた。よって、ノギス１００は、被測定物１個当たりの測定時間が長かった。そのため、数千個の製品についてノギス１００で寸法検査をする場合、検査時間が長くなる問題があった。しかも、ノギス１００は、ジョウ１１１，１２１を被測定物に押し当てる力の程度が経験に左右され、被測定物を正確に測定するのが難しかった。 However, the caliper 100 and the micrometer 200 have the following problems.
(1) The caliper 100 performs measurement by moving the second slider 130 with a finger and sandwiching the object to be measured with the jaws 111 and 121 at a predetermined pressure. There is a possibility that an error may occur due to the object to be measured being sandwiched with a larger pressure. Therefore, when measuring the object to be measured with the caliper 100, the operator has moved the second slider 130 slowly so as to keep the pressure sandwiching the object to be measured constant. Therefore, the caliper 100 has a long measurement time per object to be measured. Therefore, when dimensional inspection is performed with a caliper 100 for several thousand products, there is a problem that the inspection time becomes long. Moreover, the caliper 100 is difficult to accurately measure the object to be measured because the degree of force for pressing the jaws 111 and 121 against the object to be measured is influenced by experience.

（２）マイクロメータ２００は、エンコーダ２３３で測定ロッド２３０の停止を検知してから電動モータ２１５を所定数回転させるため、被測定物にテストストライク２２８，２２８を押し当てる力を簡単に一定にできる。しかし、そのためには、マイクロメータ２００は、エンコーダ２３３やモータエンコーダ２２１など多数の部品を要し、構造が複雑であった。 (2) Since the micrometer 200 rotates the electric motor 215 a predetermined number of times after detecting the stop of the measuring rod 230 with the encoder 233, the force for pressing the test strikes 228, 228 against the object to be measured can be easily made constant. . However, for this purpose, the micrometer 200 requires a large number of parts such as the encoder 233 and the motor encoder 221 and has a complicated structure.

本発明は、上記課題を解決するためになされたものであり、構造が簡単で、被測定物を簡易に測定できる簡易巾測定装置を提供することを目的とする。 The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a simple width measuring apparatus that has a simple structure and can easily measure an object to be measured.

（１）上記目的を達成するために、本発明の一態様に掛かる簡易巾測定装置は、被測定物の巾を測定する簡易巾測定装置において、軸と、前記軸にスライド可能に保持され、前記被測定物に接触する第１及び第２スライダと、前記第１及び前記第２スライダを前記軸の軸線方向に沿って反対向きに付勢する第１及び第２付勢部材と、前記第１及び前記第２付勢部材が前記第１及び第２スライダに付与する付勢力と反対向きの力を前記第１及び前記第２スライダに付与する紐細工部と、を有し、前記紐細工部は、前記第１及び前記第２スライダの間に配設される回転部材と、前記回転部材に設けられた第１及び第２固定ピンと、前記第１及び前記第２スライダに設けられた第１及び第２連結ピンと、前記第１及び前記第２固定ピンと前記第１及び前記第２連結ピンの周りに張った状態で設けられる紐部と、を有する。 (1) In order to achieve the above object, a simple width measuring device according to one aspect of the present invention is a simple width measuring device for measuring the width of an object to be measured, and is held slidably on the shaft. First and second sliders that contact the object to be measured, first and second biasing members that bias the first and second sliders in opposite directions along the axial direction of the shaft, and the first A stringwork portion for applying a force opposite to a biasing force applied to the first and second sliders by the first and second biasing members to the first and second sliders, and the stringwork And a rotating member disposed between the first and second sliders, first and second fixing pins provided on the rotating member, and first members provided on the first and second sliders. The first and second connecting pins, the first and second fixing pins, and the first and second pins. Having a cord portion disposed in a taut around the second connecting pin.

（２）（１）記載の発明において、前記紐部は、前記第１及び前記第２固定ピンを結ぶ直線と前記第１及び前記第２連結ピンを結ぶ直線とが直交するときの前記回転部材の配置である第１測定限界位置と、前記回転部材を前記第１測定限界位置から９０度回転させたときの配置である第２測定限界位置との間で、前記回転部材の回転を、前記第１及び前記第２固定ピンと前記第１及び前記第２連結ピンの間で張られた状態で許容する長さを有し、前記回転部材を前記第１測定限界位置から回転させ始めるときと、前記回転部材を前記第２測定限界位置へ回転させる直前のときに、前記第１及び前記第２スライダによって測定される巾の変化が小さいことが、好ましい。 (2) In the invention described in (1), the string portion is the rotating member when a straight line connecting the first and second fixing pins and a straight line connecting the first and second connecting pins are orthogonal to each other. which is the placement and the first measurement limit position, the rotation member with the second measurement limit position is arranged when rotating 90 degrees from the first measurement limit position, the rotation of said rotary member, said and when have a length that allows in a state of being stretched between said first and said second locking pin first and the second connecting pin starts rotating the rotary member from the first measurement limit position, It is preferable that a change in width measured by the first and second sliders is small immediately before the rotating member is rotated to the second measurement limit position .

（３）（１）又は（２）記載の発明において、前記第１及び前記第２スライダは、前記軸
が所定の隙間を空けて挿通される挿通孔を有することが、好ましい。 (3) In the invention described in (1) or (2), it is preferable that the first and second sliders have an insertion hole through which the shaft is inserted with a predetermined gap.

上記態様の簡易巾測定装置では、軸と、軸にスライド可能に保持され、被測定物に接触する第１及び第２スライダと、第１及び第２スライダを軸の軸線方向に沿って反対向きに付勢する第１及び第２付勢部材と、第１及び第２付勢部材が第１及び第２スライダに付与する付勢力と反対向きの力を第１及び第２スライダに付与する紐細工部と、を有し、紐細工部は、第１及び第２スライダの間に配設される回転部材と、回転部材に設けられた第１及び第２固定ピンと、第１及び第２スライダに設けられた第１及び第２連結ピンと、第１及び第２固定ピンと第１及び第２連結ピンの周りに張った状態で設けられる紐部と、を有する。 In the simple width measuring apparatus of the above aspect, the shaft, the first and second sliders that are slidably held on the shaft and are in contact with the object to be measured, and the first and second sliders are opposed to each other along the axial direction of the shaft. First and second urging members for urging the first and second urging members, and a string for imparting to the first and second sliders a force opposite to the urging force that the first and second urging members impart to the first and second sliders A stringing portion, a stringing portion including a rotating member disposed between the first and second sliders, first and second fixing pins provided on the rotating member, and first and second sliders. The first and second connecting pins provided on the first, the second fixing pins, and the string portions provided in a stretched state around the first and second connecting pins.

このような簡易巾測定装置は、回転部材が回転し、第１及び第２固定ピンが変位すると、第１及び第２連結ピンが第１及び第２スライダを介して第１及び第２付勢部材に付勢されて反対向きに移動する。このとき、紐部は、第１及び第２連結ピンと第１及び第２固定ピンの間に引っ張られた状態で設けられ、回転部材の回転角度に応じて第１及び第２連結ピンの移動量を規制する。第１及び第２スライダは、第１及び第２付勢部材の付勢力のみで被測定物に接触する。この時点で、被測定物の測定が行われる。このように、簡易巾測定装置は、エンコーダなどで第１及び第２スライダの移動量を監視しなくても、回転部材を回転させるだけで第１及び第２スライダを被測定物に所定圧で接触させて、巾測定をすることが可能である。よって、簡易巾測定装置によれば、構造が簡単で、被測定物を簡易に測定することができる。 In such a simple width measuring apparatus, when the rotating member rotates and the first and second fixing pins are displaced, the first and second connecting pins are urged by the first and second sliders via the first and second sliders. It is biased by the member and moves in the opposite direction. At this time, the string portion is provided in a state of being pulled between the first and second connecting pins and the first and second fixing pins, and the amount of movement of the first and second connecting pins according to the rotation angle of the rotating member. To regulate. The first and second sliders contact the object to be measured only with the urging forces of the first and second urging members. At this point, the measurement object is measured. As described above, the simple width measuring apparatus can rotate the first and second sliders against the object to be measured at a predetermined pressure by simply rotating the rotating member without monitoring the movement amounts of the first and second sliders with an encoder or the like. It is possible to measure the width by making contact. Therefore, according to the simple width measuring apparatus, the structure is simple and the object to be measured can be easily measured.

また上記態様の簡易巾測定装置では、紐部は、第１及び第２固定ピンを結ぶ直線と第１及び第２連結ピンを結ぶ直線とが直交するときの回転部材の配置である第１測定限界位置と、回転部材を第１測定限界位置から９０度回転させたときの配置である第２測定限界位置との間で、回転部材の回転を、第１及び第２固定ピンと第１及び第２連結ピンの間で張られた状態で許容する長さを有し、回転部材を第１測定限界位置から回転させ始めるときと、回転部材を第２測定限界位置へ回転させる直前のときに、第１及び第２スライダによって測定される巾の変化が小さい。そのため、第１及び第２スライダが被測定物に接触する瞬間の衝撃が小さく、第１及び第２スライダを被測定物に安定した圧力で接触させることが可能である。よって、簡易巾測定装置によれば、被測定物の測定精度を安定させることができる。 Moreover, in the simple width measuring apparatus of the said aspect, a string part is 1st measurement which is arrangement | positioning of a rotating member when the straight line which ties a 1st and 2nd fixing pin and the straight line which ties a 1st and 2nd connection pin orthogonally crosses. Between the limit position and the second measurement limit position, which is an arrangement when the rotation member is rotated 90 degrees from the first measurement limit position , the rotation of the rotation member is changed between the first and second fixing pins and the first and first positions. have a length which allowed in an extended state between the second coupling pin, and when the start rotating the rotary member from the first measurement limit position, when just before rotating the rotating member to the second measurement limit position, The change in width measured by the first and second sliders is small . Therefore, the impact at the moment when the first and second sliders contact the object to be measured is small, and the first and second sliders can be brought into contact with the object to be measured with a stable pressure. Therefore, according to the simple width measuring apparatus, the measurement accuracy of the object to be measured can be stabilized.

また上記態様の簡易巾測定装置では、第１及び第２スライダは、軸が所定の隙間を空けて挿通される挿通孔を有する。第１及び第２スライダは、被測定物に接触した後、第１及び第２付勢部材の付勢力により軸に対して傾く。傾いた第１及び第２スライダは、軸に片当たりしてロックされ、それ以上移動できなくなる。この時点で、被測定物が巾測定される。よって、簡易巾測定装置によれば、第１及び第２スライダが被測定物に所定圧で接触したときにロックされ、移動を制限されるので、外乱の影響を受けることなく被測定物の巾を測定することができる。 In the simple width measuring apparatus of the above aspect, the first and second sliders have insertion holes through which the shafts are inserted with a predetermined gap. The first and second sliders are inclined with respect to the shaft by the urging forces of the first and second urging members after contacting the object to be measured. The tilted first and second sliders are locked against the shaft and cannot move any further. At this point, the width of the object to be measured is measured. Therefore, according to the simple width measuring apparatus, the first and second sliders are locked when they contact the object to be measured at a predetermined pressure, and the movement is restricted. Therefore, the width of the object to be measured is not affected by disturbance. Can be measured.

次に、本発明に係る簡易巾測定装置の一実施形態について図面を参照して説明する。 Next, an embodiment of a simple width measuring apparatus according to the present invention will be described with reference to the drawings.

As shown in FIGS. 4 and 5, the urging force of the first and second rubber bands 7, 8 acts on the first and second connecting pins 21, 22 via the urging member fixing portions 32, 42. Yes. As shown in FIG. 4, when the rotating member 20 is disposed at the first measurement limit position, the pins 21 to 24 are disposed with a phase difference of 90 degrees, and the string portion 25 has a diamond shape. Has been. As shown in FIG. 5, when the rotating member 20 rotates from the first measurement limit position toward the second measurement limit position, the first and second connection pins 21 and 22 are attached to the first and second rubber bands 7 and 8. It moves in the direction away from each other by the force, and deforms the string portion 25 into a parallelogram. The string portion 25 has a horizontally long shape when the rotating member 20 rotates 90 degrees from the first measurement limit position and reaches the second measurement limit position.

＜簡易巾測定装置の特性＞
図６は、簡易巾測定装置１の特性を示す図である。縦軸は巾［ｍｍ］を示し、横軸は回転子角度θ［ｄｅｇ］を示す。
簡易巾測定装置１は、回転部材２０が、下限値（図６では３０．０５ｍｍ）を測定する第１測定限界位置から９０度回転させて、被測定物Ｗの設定巾（ここでは３１．１５ｍｍ）を測定する第２測定限界位置へ移動する場合、第１測定限界位置から２０度回転するとき（回転し始めたとき）と、８０度から９０度（第２測定限界位置）回転するとき（第２測定限界位置まで回転する直前のとき）とが、第１及び第２スライダ３，４により測定される巾の変化が小さい。これは、回転部材２０が第１測定限界位置から２０度回転するまでは、第１及び第２固定ピン２３，２４が円弧状に移動してに紐部２５に接触する位置が変わりにくいためである。また、回転部材２０が８０度から９０度（第２測定限界位置）へ回転すると、第１及び第２輪ゴム７，８の伸びが少なくなり、付勢力が小さくなるためと考えられる。 <Characteristics of simple width measuring device>
FIG. 6 is a diagram showing the characteristics of the simple width measuring apparatus 1. The vertical axis represents the width [mm], and the horizontal axis represents the rotor angle θ [deg].
In the simple width measuring apparatus 1, the rotating member 20 is rotated 90 degrees from the first measurement limit position where the lower limit value (30.05 mm in FIG. 6) is measured, and the set width (here 31.15 mm) of the workpiece W is measured. ) When measuring the second measurement limit position, when rotating 20 degrees from the first measurement limit position (when starting to rotate) and when rotating 80 degrees to 90 degrees (second measurement limit position) ( The change in the width measured by the first and second sliders 3 and 4 is small when it is just before the rotation to the second measurement limit position. This is because until the rotating member 20 rotates 20 degrees from the first measurement limit position, the position where the first and second fixing pins 23, 24 move in an arc shape and contact with the string portion 25 is unlikely to change. is there. Further, it is considered that when the rotating member 20 is rotated from 80 degrees to 90 degrees (second measurement limit position), the first and second rubber bands 7 and 8 are less stretched and the urging force is decreased.

＜動作説明＞
続いて、簡易巾測定装置１の動作について説明する。
簡易巾測定装置１は、例えば図３に示すように、被測定物Ｗの内径寸法を測定するために用いられる。被測定物Ｗは、線材を巻回したものや、可撓性チューブなど、変形しやすいものである。 <Description of operation>
Then, operation | movement of the simple width measuring apparatus 1 is demonstrated.
The simple width measuring device 1 is used for measuring the inner diameter dimension of the workpiece W, for example, as shown in FIG. The object to be measured W is easily deformed such as a wound wire or a flexible tube.

簡易巾測定装置１は、回転部材２０を第１測定限界位置に配置した状態で、第１及び第２スライダ３、４の先端を被測定物Ｗの孔部に挿入する。その後、回転駆動部２７により回転軸２６を回転させる。回転部材２０は、回転軸２６と一体的に回転し、第１及び第２固定ピン２３，２４の配置を相対的に回転方向へずらす。第１及び第２固定ピン２３，２４が第１及び第２連結ピン２１，２２に近づくにつれて、第１及び第２連結ピン２１，２２は、第１及び第２輪ゴム７，８の付勢力によって第１及び第２固定部５，６側へ移動する。これにより、紐部２５の形状が、菱形から平行四辺形に変化する。 The simple width measuring apparatus 1 inserts the tips of the first and second sliders 3 and 4 into the holes of the object to be measured W with the rotating member 20 disposed at the first measurement limit position. Thereafter, the rotation shaft 26 is rotated by the rotation drive unit 27. The rotating member 20 rotates integrally with the rotating shaft 26 and relatively displaces the arrangement of the first and second fixing pins 23 and 24 in the rotating direction. As the first and second fixing pins 23, 24 approach the first and second connecting pins 21, 22, the first and second connecting pins 21, 22 are caused by the urging force of the first and second rubber bands 7, 8. It moves to the first and second fixing parts 5 and 6 side. Thereby, the shape of the string part 25 changes from a rhombus to a parallelogram.

第１及び第２スライダ３，４は、硬球３４，４４が被測定物Ｗに接触するまでは、第１及び第２輪ゴム７，８の張力と紐部２５の張力とがバランスし、軸９に対して傾かずにスライドする。第１及び第２スライダ３，４は、硬球３４，４４が被測定物Ｗに接触して移動を制限された後、第１及び第２輪ゴム７，８により第１及び第２固定部５，６側へ更に引っ張られてバランスを崩し、軸９に対して傾く。すると、軸受部３１，４１が軸９にこじれ、第１及び第２スライダ３，４が第１及び第２固定部５，６側へ移動しなくなる。この状態において、被測定物Ｗの巾が測定される。 The first and second sliders 3 and 4 balance the tension of the first and second rubber bands 7 and 8 with the tension of the string portion 25 until the hard balls 34 and 44 come into contact with the object W to be measured. Slide without tilting. The first and second sliders 3 and 4 are moved by the first and second rubber bands 7 and 8 after the hard balls 34 and 44 are in contact with the object W to be measured and then moved. It is further pulled to the 6 side to break the balance and tilts with respect to the shaft 9. Then, the bearing portions 31 and 41 are twisted on the shaft 9 and the first and second sliders 3 and 4 do not move to the first and second fixing portions 5 and 6 side. In this state, the width of the workpiece W is measured.

第１及び第２スライダ３，４が測定する巾は、回転部材２０が第１測定限界位置から２０度回転し始めるとき、変化率が小さいが、その後の変化率が大きくなり、さらにその後、第２測定限界位置まで回転する直前のときに、変化率が小さくなる（図６参照）。換言すれば、第１及び第２スライダ３，４は、ゆっくり加速しながら移動し始め、被測定物Ｗに接触する直前で減速して、第１及び第２輪ゴム７，８の弾性力のみで被測定物Ｗに接触する。そのため、第１及び第２スライダ３，４は、被測定物Ｗに接触する際の荷重が小さく、安定している。よって、簡易巾測定装置１は、第１及び第２スライダ３，４を被測定物Ｗに接触させたときの衝撃が大きいなどの外乱を排除し、巾測定を行うことができる。 The width measured by the first and second sliders 3 and 4 is small when the rotary member 20 starts to rotate 20 degrees from the first measurement limit position, but the rate of change thereafter becomes large, and then 2. The rate of change becomes small immediately before the rotation to the measurement limit position (see FIG. 6) . If conversion words, the first and second sliders 3 and 4, begins to move with gentle acceleration and deceleration just before contact with the workpiece W, the elastic force of the first and second rubber band 7, 8 only To contact the workpiece W. Therefore, the first and second sliders 3 and 4 have a small load when contacting the workpiece W and are stable. Therefore, the simple width measuring apparatus 1 can perform the width measurement by eliminating disturbance such as a large impact when the first and second sliders 3 and 4 are brought into contact with the workpiece W.

上記のようにして測定が終了したら、回転駆動部２７により回転軸２６を逆回転させる。回転部材２０が回転軸２６と一体的に逆回転することにより、第１及び第２固定ピン２３，２４が紐部２５を介して第１及び第２連結ピン２１，２２を引っ張り、第１及び第２スライダ３，４を第１及び第２輪ゴム７，８の付勢力に抗して引き寄せる。回転部材２０を第１測定限界位置まで戻したら、被測定物Ｗを交換し、次の被測定物Ｗを測定する。 When the measurement is completed as described above, the rotation shaft 26 is rotated reversely by the rotation driving unit 27. When the rotating member 20 is reversely rotated integrally with the rotating shaft 26, the first and second fixing pins 23 and 24 pull the first and second connecting pins 21 and 22 through the string portion 25, and the first and second The second sliders 3 and 4 are attracted against the urging force of the first and second rubber bands 7 and 8. When the rotating member 20 is returned to the first measurement limit position, the workpiece W is replaced and the next workpiece W is measured.

このようにして巾を測定された被測定物Ｗは、測定値が設置巾の誤差範囲内であれば、良品と判断される一方、測定値が被測定物Ｗの誤差範囲以外であれば、不良品と判断される。 The object W whose width is measured in this way is determined to be a non-defective product if the measured value is within the error range of the installation width, while if the measured value is outside the error range of the object W, Judged as defective.

＜作用効果＞
以上説明したように、本実施形態の簡易巾測定装置１は、軸９と、軸９にスライド可能に保持され、被測定物Ｗに接触する第１及び第２スライダ３，４と、第１及び第２スライダ３，４を軸９の軸線方向に沿って反対向きに付勢する第１及び第２輪ゴム７，８と、第１及び第２輪ゴム７，８が第１及び第２スライダ３，４に付与する付勢力と反対向きの力を第１及び第２スライダ３，４に付与する紐細工部２と、を有し、紐細工部２は、第１及び第２スライダ３，４の間に配設される回転部材２０と、回転部材２０に設けられた第１及び第２固定ピン２３，２４と、第１及び第２スライダ３，４に設けられた第１及び第２連結ピン２１，２２と、第１及び第２固定ピン２３，２４と第１及び第２連結ピン２１，２２の周りに張った状態で設けられる紐部２５と、を有する。 <Effect>
As described above, the simple width measuring apparatus 1 of the present embodiment includes the shaft 9, the first and second sliders 3 and 4 that are slidably held on the shaft 9 and are in contact with the object W to be measured, and the first The first and second rubber bands 7, 8 that urge the second sliders 3, 4 in opposite directions along the axial direction of the shaft 9, and the first and second rubber bands 7, 8 are the first and second sliders 3. , 4 and a stringwork portion 2 for imparting a force opposite to the biasing force applied to the first and second sliders 3, 4, and the stringwork portion 2 includes the first and second sliders 3, 4. A rotating member 20 disposed between the first and second fixing pins 23 and 24 provided on the rotating member 20, and first and second couplings provided on the first and second sliders 3 and 4. Provided with the pins 21 and 22 stretched around the first and second fixing pins 23 and 24 and the first and second connecting pins 21 and 22 Having a cord portion 25, a being.

このような簡易巾測定装置１は、回転部材２０が回転し、第１及び第２固定ピン２３，２４が変位すると、第１及び第２連結ピン２１，２２が第１及び第２スライダ３，４を介して第１及び第２輪ゴム７，８に付勢されて反対向きに移動する。このとき、紐部２５は、第１及び第２連結ピン２１，２２と第１及び第２固定ピン２３，２４の間に引っ張られた状態で設けられ、回転部材２０の回転角度に応じて第１及び第２連結ピン２１，２２の移動量を規制する。第１及び第２スライダ３，４は、第１及び第２輪ゴム７，８の付勢力のみで被測定物Ｗに接触する。この時点で、被測定物Ｗの測定が行われる。このように、簡易巾測定装置１は、エンコーダなどで第１及び第２スライダ３，４の移動量を監視しなくても、回転部材２０を回転させるだけで第１及び第２スライダ３，４を被測定物Ｗに所定圧で接触させて、巾測定をすることが可能である。よって、簡易巾測定装置１によれば、構造が簡単で、被測定物Ｗを簡易に測定することができる。 In such a simple width measuring apparatus 1, when the rotating member 20 rotates and the first and second fixing pins 23 and 24 are displaced, the first and second connecting pins 21 and 22 become the first and second sliders 3 and 3. 4 urged by the first and second rubber bands 7 and 8 through 4 and moves in opposite directions. At this time, the string portion 25 is provided in a state of being pulled between the first and second connecting pins 21 and 22 and the first and second fixing pins 23 and 24, and the string portion 25 is changed according to the rotation angle of the rotating member 20. The movement amount of the first and second connecting pins 21 and 22 is restricted. The first and second sliders 3 and 4 are in contact with the object W to be measured only by the urging forces of the first and second rubber bands 7 and 8. At this time, the measurement object W is measured. As described above, the simple width measuring apparatus 1 does not monitor the movement amount of the first and second sliders 3 and 4 with an encoder or the like, but simply rotates the rotary member 20 to rotate the first and second sliders 3 and 4. It is possible to measure the width by contacting the object to be measured W with a predetermined pressure. Therefore, according to the simple width measuring apparatus 1, the structure is simple and the workpiece W can be easily measured.

また簡易巾測定装置１では、紐部２５は、下限値を測定する第１測定限界位置と、被測定物Ｗの設定巾に対応する上限値を測定する第２測定限界位置との間で回転部材２０の回転を、第１及び第２固定ピン２３，２４と第１及び第２連結ピン２１，２２の間で張られた状態で許容する長さを有する。このような簡易巾測定装置１は、回転部材２０を第１測定限界位置から回転させ始めるときと、回転部材２０を第２測定限界位置へ回転させる直前のときに、第１及び第２スライダ３，４によって測定される巾の変化が小さい。そのため、第１及び第２スライダ３，４が被測定物Ｗに接触する瞬間の衝撃が小さく、第１及び第２スライダ３，４を被測定物Ｗに安定した圧力で接触させることが可能である。よって、簡易巾測定装置１によれば、被測定物Ｗの測定精度を安定させることができる。 In the simple width measuring device 1, the string portion 25 rotates between a first measurement limit position for measuring the lower limit value and a second measurement limit position for measuring the upper limit value corresponding to the set width of the workpiece W. The member 20 has a length that allows rotation of the member 20 while being stretched between the first and second fixing pins 23 and 24 and the first and second connecting pins 21 and 22. Such a simple width measuring device 1 includes the first and second sliders 3 when starting to rotate the rotating member 20 from the first measurement limit position and immediately before rotating the rotating member 20 to the second measurement limit position. , 4 has a small change in width. Therefore, the impact at the moment when the first and second sliders 3 and 4 contact the object to be measured W is small, and the first and second sliders 3 and 4 can be brought into contact with the object to be measured W with a stable pressure. is there. Therefore, according to the simple width measuring apparatus 1, the measurement accuracy of the workpiece W can be stabilized.

また簡易巾測定装置１では、第１及び第２スライダ３，４は、軸９が所定の隙間を空けて挿通される挿通孔（軸受部３１，４１の貫通孔）を有する。第１及び第２スライダ３，４は、被測定物Ｗに接触した後、第１及び第２輪ゴム７，８の付勢力により軸９に対して傾く。傾いた第１及び第２スライダ３，４は、軸９に片当たりしてロックされ、それ以上移動できなくなる。この時点で、被測定物Ｗが巾測定される。よって、簡易巾測定装置１によれば、第１及び第２スライダ３，４が被測定物Ｗに所定圧で接触したときにロックされ、移動を制限されるので、外乱の影響を受けることなく被測定物Ｗの巾を測定することができる。
また回転部材の測定開始状態を例えば、回転角度３０度程度とすることで、回転部材の回転開始時の第１及び第２スライダ３，４の移動速度を速くすることができ、被測定物に接触する時を除いて、第１及び第２スライダ３，４の移動速度を比較的速くすることができる。これにより、測定開始の安定、測定時間の短縮を両立させることが可能である。このような場合を含めて、測定開始時の回転角度を固定するための手段を設けても良い。 Further, in the simple width measuring apparatus 1, the first and second sliders 3 and 4 have insertion holes (through holes of the bearing portions 31 and 41) through which the shaft 9 is inserted with a predetermined gap. The first and second sliders 3 and 4 are tilted with respect to the shaft 9 by the urging force of the first and second rubber bands 7 and 8 after contacting the object to be measured W. The tilted first and second sliders 3 and 4 are locked against the shaft 9 so that they cannot move any further. At this time, the width of the workpiece W is measured. Therefore, according to the simple width measuring apparatus 1, since the first and second sliders 3 and 4 are locked and contacted with the object to be measured W at a predetermined pressure, the movement is restricted, so that there is no influence of disturbance. The width of the workpiece W can be measured.
In addition, by setting the measurement start state of the rotating member to, for example, a rotation angle of about 30 degrees, it is possible to increase the moving speed of the first and second sliders 3 and 4 when the rotation of the rotating member is started. Except for the time of contact, the moving speed of the first and second sliders 3 and 4 can be made relatively high. As a result, it is possible to achieve both stable measurement start and shortened measurement time. Including such a case, a means for fixing the rotation angle at the start of measurement may be provided.

続いて、簡易巾測定装置１の実施例について説明する。 Then, the Example of the simple width measuring apparatus 1 is demonstrated.

実施例１の簡易巾測定装置１は、図１に示すように、軸９と、第１スライダ３と、第２スライダ４との三組で結合されている。第１及び第２スライダ３，４が第１及び第２固定部５，６に当接し、第１及び第２輪ゴム７，８のアースと同じに止まり、且つ、回転部材２０が紐細工部２の中心部で回転した時、第１及び第２スライダ３，４が紐部２５の輪郭形状の変化に応じて同じ量ずつ動く。このとき、簡易巾測定装置１が測定する巾の変化は、図６に示すＸ１，Ｘ２に示すようになる。硬球３４，４４は、第１及び第２スライダ３，４を介して紐細工部２に組み付けられ、硬球３４，４４の位置を機械的に決める。 As shown in FIG. 1, the simple width measuring apparatus 1 according to the first embodiment is coupled in three sets of a shaft 9, a first slider 3, and a second slider 4. The first and second sliders 3 and 4 come into contact with the first and second fixing portions 5 and 6 and remain the same as the ground of the first and second rubber bands 7 and 8, and the rotating member 20 is the string work portion 2. The first and second sliders 3 and 4 move by the same amount in accordance with the change in the contour shape of the string portion 25. At this time, changes in the width measured by the simple width measuring apparatus 1 are as indicated by X1 and X2 shown in FIG. The hard balls 34 and 44 are assembled to the string work portion 2 via the first and second sliders 3 and 4 to mechanically determine the positions of the hard balls 34 and 44.

図３に示す第１及び第２スライダ３，４は、軸受部３１，４１の軸方向長さが同じ値とされている。しかも、軸受部３１，４１は、図７に示す力Ｆｄｄｄに相当する図８の力Ｆｄｄｄ１により動く限界まで小さくして、軸９にセットされている。 FIG. 7 is a diagram illustrating the force applied to the slider 4 (3). FIG. 8 is a diagram for explaining the locking operation of the slider 4 (3).
The first and second sliders 3 and 4 shown in FIG. 3 have the same length in the axial direction of the bearing portions 31 and 41. Moreover, the bearing portions 31 and 41 are set on the shaft 9 so as to be reduced to the limit of movement by the force Fddd1 in FIG. 8 corresponding to the force Fddd shown in FIG.

図９は、紐細工部２'を概念的に示す図である。
図９に示すように、回転部材２０が第１測定限界位置にあるときに、第２連結ピン２２を頂点とする角度θｓを約９０度に決めたことを、４４．６度にするように、第１及び第２連結ピン２１，２２を配設して（二点鎖線部参照）、紐細工部２'を構成する。紐細工部２'は、回転部材２０を第１測定限界位置に配置しているときに、紐部２５が、第１及び第２固定ピン２３，２４と第１及び第２連結ピン２１，２２との間の辺ｄｄが１４ｍｍであるとする。さらに、第１及び第２固定ピン２３，２４のピン径ｂｂを３ｍｍとする。この場合、緒元で｛ｂｂ＝３（ｍｍ）、ｄｄ＝１４（ｍｍ）、θｓ＝４４．６（度）｝となるし、紐部２５の長さは約５３ｍｍとなる。第１及び第２スライダ３，４の間の距離で巾測定する状態では、回転部材２０が第１測定限界位置から２０度回転するまでの間と、回転部材２０が第１測定限界位置を基準として８０度から９０度回転するまでの間で、巾の変化が少ない。 FIG. 9 is a diagram conceptually showing the stringwork portion 2 ′.
As shown in FIG. 9 , when the rotating member 20 is at the first measurement limit position, the angle θs having the second connecting pin 22 as the apex is determined to be about 90 degrees, so that it becomes 44.6 degrees. The first and second connecting pins 21 and 22 are disposed (see the two-dot chain line portion) to constitute the stringwork portion 2 ′. When the string member 2 'is arranged with the rotating member 20 at the first measurement limit position, the string portion 25 has the first and second fixing pins 23, 24 and the first and second connecting pins 21, 22. The side dd between and is 14 mm. Further, the pin diameter bb of the first and second fixing pins 23 and 24 is 3 mm. In this case, the specifications are {bb = 3 (mm), dd = 14 (mm), θs = 44.6 (degrees)}, and the length of the string portion 25 is about 53 mm. In the state of width measured by the distance between the first and second sliders 3 and 4, and between the rotary member 20 until the rotating 20 degrees from the first measurement limit position, the rotation member 20 is a first measurement limit position There is little change in width between the rotation of 80 degrees and 90 degrees as a reference.

図８に示す軸９の軸心から硬球４４（３４）が被測定物Ｗに接触する位置までの距離ｃｃｃの値が５０ｍｍのとき、軸受部４１（３１）の全長ａａａを５ｍｍとする。 When the value of the distance ccc from the axis of the shaft 9 shown in FIG. 8 to the position where the hard ball 44 (34) contacts the workpiece W is 50 mm, the total length aaa of the bearing portion 41 (31) is 5 mm .

紐部２５の材質を、ステンレスやグラスファーバーなど布より強いものとする。これに
より、紐部２５が強くなり、荷重による紐部２５の長さの変化が影響しないとした。 The material of the string portion 25 is made stronger than cloth such as stainless steel or glass fiber. Thereby, the string part 25 became strong and the change of the length of the string part 25 due to the load was not affected.

図６のＸ１とＸ２の速度減少は大きく、回転部材２０を無意識に回転しても回転始めのＸ１の急加速が起こらない抑えと、第１及び第２スライダ３，４が被測定物Ｗに接触するＸ２付近では、滑らかな速度の減速をする。これは、高技能者が被測定物Ｗを測定する場合の動作を、間接的に実施している。 As shown in FIGS. 13 and 15, the specifications are designed according to the movement amounts of the first and second sliders 3 and 4 from the scatter diagrams.
The speed reduction of X1 and X2 in FIG. 6 is large, and even if the rotating member 20 is rotated unintentionally, the first and second sliders 3 and 4 are attached to the object W to be measured. In the vicinity of the contacting X2, the vehicle is decelerated at a smooth speed. This indirectly performs an operation when a highly skilled person measures the workpiece W.

図１２のピン２１〜２４の直径をそれぞれ３ｍｍと決めた時、径緒元｛３（ｍｍ），３（ｍｍ），３（ｍｍ），３（ｍｍ）｝とすると、径緒元を｛８（ｍｍ），３（ｍｍ），３（ｍｍ），３（ｍｍ）｝や｛８（ｍｍ），８（ｍｍ），３（ｍｍ），３（ｍｍ）｝や｛８（ｍｍ），３（ｍｍ），８（ｍｍ），３（ｍｍ）｝に変更すると、紐部２５の長さが変化する。図１２に示す角度θｓを図１４に示すように大きくすると紐部２５の長さは短く、図１２に示すように角度θｓを小さくすると紐部２５は長くなる。ピン径ｂｂを６ｍｍ以上１０ｍｍ以下、辺ｄｄを１５ｍｍ以上４５ｍｍ以下、角度θｓを３０度以上９０度以下と限定して、下記数１〜数３で演算した結果を図１６に示す（３×３×３＝２７の例）。 When the diameters of the pins 21 to 24 in FIG. 12 are determined to be 3 mm, if the diameter is {3 (mm), 3 (mm), 3 (mm), 3 (mm)}}, the diameter is {8 (Mm), 3 (mm), 3 (mm), 3 (mm)} or {8 (mm), 8 (mm), 3 (mm), 3 (mm)} or {8 (mm), 3 ( mm), 8 (mm), 3 (mm)}, the length of the string portion 25 changes. When the angle θs shown in FIG. 12 is increased as shown in FIG. 14, the length of the string portion 25 is shortened, and when the angle θs is decreased as shown in FIG. 12, the string portion 25 is lengthened. FIG. 16 shows the results calculated by the following equations 1 to 3 with the pin diameter bb being 6 mm or more and 10 mm or less, the side dd being 15 mm or more and 45 mm or less, and the angle θs being 30 degrees or more and 90 degrees or less.

図１７は、簡易巾測定装置１の移動特性を示す図である。縦軸は特性値を示し、横軸はピン径ｂｂ［ｍｍ］と、辺ｄｄ［ｍｍ］と、角度θｓ［ｄｅｇ］を示す。
これにより、（イ）ピン２１〜２４のピン径ｂｂを大きくする程、第１及び第２スライダ３，４の移動が小さくなること、（ロ）辺ｄｄを大きくする程、第１及び第２スライダ３，４の移動が大きくなること、（ハ）紐部２５の初期設定（回転角度θ＝０度）の時の角度θｓが大きい程、第１及び第２スライダ３，４の移動が大きくなること、を図１７で確認し、紐細工部２の紐緒元を決める。 FIG. 17 is a diagram illustrating the movement characteristics of the simple width measuring apparatus 1. The vertical axis represents the characteristic value, and the horizontal axis represents the pin diameter bb [mm], the side dd [mm], and the angle θs [deg].
Accordingly, (a) the movement of the first and second sliders 3 and 4 decreases as the pin diameter bb of the pins 21 to 24 increases, and (b) the first and second increase as the side dd increases. The movement of the sliders 3 and 4 increases, and (c) the movement of the first and second sliders 3 and 4 increases as the angle θs at the initial setting (rotation angle θ = 0 degree) of the string portion 25 increases. This is confirmed in FIG. 17, and the string origin of the stringwork unit 2 is determined.

高熟練者による滑らかな第１及び第２スライダ３，４の駆動の意味を、１回微分、２回微分共滑らかな駆動と解釈し、上記実施例６に辺ｄｄを大きく、ピン径ｂｂを小さく、角度θｓを小さくして、移動量を必要最小にすると良いことが推定され、交互作用も含めて考えると複雑である。そこで、三元配置の数値実験値から、ピン径ｂｂの主効果、辺ｄｄの主効果、角度θｓの主効果で整理した図１７を書き、図示移動量を参照して、紐緒元を決める。 The meaning of smooth driving of the first and second sliders 3 and 4 by a highly skilled person is interpreted as smooth driving for both the first differential and the second differential, and the side dd is increased in Example 6 and the pin diameter bb is It is estimated that it is preferable to reduce the angle θs to minimize the amount of movement, and it is complicated when considering the interaction. Therefore, FIG. 17 arranged by the main effect of the pin diameter bb, the main effect of the side dd, and the main effect of the angle θs is written from the numerical experimental values of the three-way arrangement, and the string origin is determined with reference to the illustrated movement amount. .

図１８は、簡易巾測定システム５０の正面図である。図１９は、市販テーブル５２の一例を示す図である。図中横方向をＸ軸、図中手前から奥方向をＹ軸、図中上下方向をＺ軸とする。
被測定物ＷをＸＹテーブル５１の上に固定して、高精度に位置決めした測定を企画したがＸＹの移動は、Ｘ軸用ハンドル５１ａ及びＹ軸用ハンドル５１ｂの１回転当たり０．５ｍｍであり、１０ｍｍ移動させる為にハンドル５１ａ，５１ｂを２０回転させる必要があり、作業性の改善が必要となった。そこで、図１９に示す市販テーブル５２を図１８に示すように使用して、Ｙ軸移動を早めて改善を狙った。また、図１８に示す簡易巾測定システム５０に簡易巾測定装置１を使用して測定精度の確保も狙った。 FIG. 18 is a front view of the simple width measurement system 50. FIG. 19 is a diagram illustrating an example of the commercially available table 52. The horizontal direction in the figure is the X axis, the front to the back in the figure is the Y axis, and the vertical direction in the figure is the Z axis.
The measurement was planned with the workpiece W fixed on the XY table 51 and positioned with high accuracy, but the movement of XY was 0.5 mm per rotation of the X-axis handle 51a and the Y-axis handle 51b. In order to move 10 mm, it is necessary to rotate the handles 51a and 51b 20 times, and it is necessary to improve workability. Therefore, the commercial table 52 shown in FIG. 19 was used as shown in FIG. Further, the simple width measuring device 1 was used in the simple width measuring system 50 shown in FIG.

作業性の改善の為には、Ｙ軸方向の荒い移動に、図１９のハンドル５３を１回転弱で１０ｍｍの移動が可能となる為、作業性が改善されるが、構成品が増加した為、駆動面のクリアランスによるガタも加算される為、第１及び第２スライダ３，４の先端位置が不安定となる分を、市販テーブル５２のロック手段５４でロックし、ガタ殺しをすることとした。このロック状態で簡易巾測定装置１の効果も発揮させて、円滑な測定を行うこととしたが、手作業で被測定物Ｗの取り付けを行う時に、手が角に当たり怪我をする危険性を減らす為、おおきなスペースを確保させると、図１８に示すアーム５５が大きくなり、撓みが増加し、固有振動数が小さくなり、外部振動を拾う可能性が高まる。しかし、簡易巾測定装置１は、第１及び第２スライダ３，４が被測定物Ｗに接触したときに傾いてロックされ、逆入力を防止する。よって、図１８に示す簡易巾測定システム５０は、技術検討に安全も絡んで、総合の評価を悪化させる状態を改善する、ロジックが構成される。 In order to improve workability, the handle 53 of FIG. 19 can be moved 10 mm with less than one rotation for rough movement in the Y-axis direction, so workability is improved, but the number of components has increased. Since the backlash due to the clearance of the drive surface is also added, the amount of instability of the tip positions of the first and second sliders 3 and 4 is locked by the locking means 54 of the commercial table 52 to kill the backlash. did. In this locked state, the effect of the simple width measuring device 1 is also exhibited and smooth measurement is performed. However, when attaching the workpiece W manually, the risk of injury due to the hand hitting the corner is reduced. Therefore, if a large space is secured, the arm 55 shown in FIG. 18 becomes large, the flexure increases, the natural frequency decreases, and the possibility of picking up external vibration increases. However, the simple width measuring apparatus 1 is tilted and locked when the first and second sliders 3 and 4 come into contact with the workpiece W to prevent reverse input. Therefore, a simple width measurement system 50 shown in FIG. 18, it entangled safe for technical studies to improve the state of exacerbating the overall of evaluation logic is configured.

実施例８の一発目の調整で実用となる場合と、強い外乱が突如加わり、再度調整が必要な場合について説明する。図１８の軸９に応じて動く、第１スライダ３の軸方向長さを、図７のａａａで示せる時、軸９の径と第１スライダ３の穴（軸受部３１の貫通孔）の隙間ｂｂｂを、図７で示すａａａと、逆入力Ｆｃｃｃに応じて、点ａａａ１と点ａａａ２とで、真実接触面積も決まると考える。逆入力Ｆｃｃｃが大きい時は接触面積も増大するし、逆入力Ｆｃｃｃが小さい時は接触面積も小さくなる。逆入力Ｆｃｃｃに応じた応力が増大すると、摩擦力も瞬間的に大きくなり、動きを止め、共振現象発生の抵抗となる。図７で示すａａａが小さい時は抵抗が大きく、図７で示すａａａが大きい時は抵抗が小さくなる。点ａａａ１、点ａａａ２の各稜部に面取りや丸みを付けるとこの応力も緩和され、永久変形も小さくなる。
第１及び第２輪ゴム７，８の本数を増加に応じた変形も発生し、時系列的に変化がおこり、接触面の馴染みが進行し、慣らしが変化し動きも滑らかとなる。 A description will be given of a case where the first adjustment in Example 8 is practical and a case where a strong disturbance suddenly occurs and the adjustment is necessary again. When the axial length of the first slider 3 that moves according to the shaft 9 in FIG. 18 can be indicated by aaa in FIG. 7, the gap between the diameter of the shaft 9 and the hole of the first slider 3 (through hole of the bearing portion 31). For bbb, the true contact area is also determined by the points aaa1 and aaa2 according to aaa shown in FIG. 7 and the reverse input Fccc. The contact area increases when the reverse input Fccc is large, and the contact area decreases when the reverse input Fccc is small. When the stress corresponding to the reverse input Fccc increases, the frictional force also increases momentarily, stops the movement, and becomes a resistance for occurrence of a resonance phenomenon. The resistance is large when aaa shown in FIG. 7 is small, and the resistance is small when aaa shown in FIG. 7 is large. If chamfering or rounding is applied to the ridges of the points aaa1 and aaa2, this stress is alleviated and permanent deformation is reduced.
As the number of the first and second rubber bands 7 and 8 increases, deformation also occurs and changes in a time-series manner, the familiarity of the contact surface advances, the break-in changes, and the movement becomes smooth.

図７に示すように、軸９の案内でスムーズに動く第１及び第２スライダ３，４が硬球３４，４４から掛かる外乱には追従しなく、第１及び第２輪ゴム７，８からの力Ｆｄｄｄに応じた動きを良くする為に、第１及び第２輪ゴム７，８から軸９の軸心までの距離ｄｄｄを小さく、軸９の軸心から硬球３４，４４が被測定物Ｗに接触する位置までの距離ｃｃｃを大きくすると良い。距離ｃｃｃの寸法をａａａの寸法で割った値が大きいとき、ロックが強く効き、小さい時は小さい、過剰に利かせると永久変形も増加する。永久変形は、初期馴染み的現象で即止まる。ロックを適度な値とする為、ｔａｎ−１（ｂｂｂ／ａａａ）を０．１〜０．３とすることや、外乱小では０．０５〜０．１とすること０．０１〜０．０５とすることを考える。外乱が無い時は、逆入力防止が不要であるので、０とすることを期待した調整を進める。摩擦係数がゼロとか外乱がゼロは、理想的な仮定（数学的な限界値）からの話で確率ゼロでの存在であるが、パソコンモデルを構築して、理想値との対比で適正な評価を行う、逆入力ロックと、紐細工部２の考案として示す（ハード含みの調整を示す。） As shown in FIG. 7, the first and second sliders 3, 4 that move smoothly by the guide of the shaft 9 do not follow the disturbance applied from the hard balls 34, 44, and force from the first and second rubber bands 7, 8. In order to improve the movement according to Fddd, the distance ddd from the first and second rubber bands 7 and 8 to the shaft center of the shaft 9 is made small, and the hard balls 34 and 44 contact the workpiece W from the shaft center of the shaft 9. It is preferable to increase the distance ccc to the position. When the value obtained by dividing the distance ccc by the dimension of aaaa is large, the lock works strongly, and when it is small, it is small. When excessively used, permanent deformation increases. Permanent deformation stops immediately with an initial familiar phenomenon. In order to set the lock to an appropriate value, tan-1 (bbb / aaa) is set to 0.1 to 0.3, or 0.05 to 0.1 when the disturbance is small 0.01 to 0.05 Think about it. When there is no disturbance, it is not necessary to prevent reverse input, so adjustment that is expected to be zero is advanced. The coefficient of friction is zero Toka disturbance is zero, which is the presence of a probability zero in the story from the ideal assumptions (mathematical limit value), to build a personal computer model, appropriate in comparison with the ideal value Shown as an idea of reverse input lock and stringwork section 2 for evaluation (adjustment including hardware is shown).

図２０は、第１及び第２スライダ３，４の巾と回転部材２０の回転角度との関係を示す図である。縦軸は巾［ｍｍ］を示し、横軸は回転部材回転角度［ｄｅｇ］を示す。図２１は、第１及び第２スライダ３，４の移動速度と回転部材２０の回転角度との関係を示す図である。縦軸は巾速度［ｍｍ／ｄｅｇ］を示し、横軸は回転部材回転角度［ｄｅｇ］を示す。図２２は、第１及び第２スライダ３，４の加速度と回転部材２０の回転角度との関係を示す図である。縦軸は巾加速度［ｍｍ／ｄｅｇ２］を示し、横軸は回転部材回転角度［ｄｅｇ］を示す。
回転部材２０をθ度回転駆動すると、前述紐部２５の状態が変わり、第１及び第２スライダ３，４間の巾が図２０の如く変わり、角度：θを等速駆動（変化量ｄθ［ｄｅｇ／ｓｅｃ］が一定）すると、図２０のＹ１とＹ２での変化は、高技能者の操作に似たものとなった。回転角度θ＝０、９０度速度も図２１でゼロであり、加速度も図２２に示す滑らかな変化をすることが出来たので、これを、高技能者の操作模倣を完成したとみなしている（図６、図２０のθ０，９０付近参照）。 FIG. 20 is a diagram showing the relationship between the widths of the first and second sliders 3 and 4 and the rotation angle of the rotating member 20. The vertical axis indicates the width [mm], and the horizontal axis indicates the rotation angle [deg] of the rotating member. FIG. 21 is a diagram showing the relationship between the moving speed of the first and second sliders 3 and 4 and the rotation angle of the rotating member 20. The vertical axis indicates the width speed [mm / deg], and the horizontal axis indicates the rotation angle of the rotating member [deg]. FIG. 22 is a diagram showing the relationship between the acceleration of the first and second sliders 3 and 4 and the rotation angle of the rotating member 20. The vertical axis represents the width acceleration [mm / deg2], and the horizontal axis represents the rotating member rotation angle [deg].
When the rotary member 20 is driven to rotate by θ degrees, the state of the string portion 25 changes, the width between the first and second sliders 3 and 4 changes as shown in FIG. 20, and the angle: θ is driven at a constant speed (change amount dθ [ deg / sec] is constant), the change at Y1 and Y2 in FIG. 20 resembles the operation of a highly skilled person. The rotation angle θ = 0, the 90-degree speed is zero in FIG. 21, and the acceleration can be smoothly changed as shown in FIG. 22. Therefore, it is considered that the operation imitation of the highly skilled person is completed. (See the vicinity of θ0, 90 in FIGS. 6 and 20).

高技能者の技能の模倣を完成した後、加速度の調整で、慣性力を調整し、輪ゴム７，８の本数で掛かる力の中央値を調整し、更なる改善に調整できる土台が完成した。この技術を利用して、第１及び第２スライダ３，４が被測定物Ｗに接触する圧力を測定して、高技能者の納得する測定を探す体制を構築できる可能性が出た。すると、輪ゴム７，８の微小力と、微妙な速度変化と、加速度変化を把握して第１及び第２スライダ３，４が被測定物Ｗを押し付ける押付力の構成を多変量で解析できる体制が完成した。これに、前述実施例同様に、外乱や固有振動数、共振に対する対応も含めた例が完成する。このロジックは、市販されている統計学のソフトを利用したり、手書きのメモの助けも使用したロジックが完成した。 After imitating the skills of highly skilled workers, the foundation that can be adjusted for further improvement by adjusting the inertial force by adjusting the acceleration, adjusting the median value of the force applied by the number of rubber bands 7, 8 was completed. By using this technique, there is a possibility that a system can be constructed in which the pressure at which the first and second sliders 3 and 4 are in contact with the object W to be measured is searched for the measurement that the skilled worker is satisfied with. Then, the system that can grasp the minute force of the rubber bands 7 and 8, the subtle speed change and the acceleration change and analyze the structure of the pressing force with which the first and second sliders 3 and 4 press the workpiece W in a multivariate manner. Was completed. This completes an example including measures for disturbance, natural frequency, and resonance, as in the previous embodiment. This logic was completed using commercially available statistical software and with the help of handwritten notes.

実施例１１の速度、加速度を図２２に示す様に、５次回帰式（回帰係数も表示すると更に良い）で示し、紐細工部２の設計を行う場合に、図２３に示す角度θｓが４０度や、図２４の角度θｓの９０度も、ピン２１〜２４の外側を通る紐部２５の長さ（ＬＬ０）を"ＬＬ０＝４×（ｅｅ−ｂｂ）＋π×ｅｅ"で計算で求めることができる。逆算すると、ＬＬ０とピン径ｂｂと角度θｓの関係も決まる。逆算式を利用し紐部２５の長さを入力とした計算を行い、[ＬＬ０，ｅｅ、θｓ]の三元の演算表から、望む条件を探す方法も良い。 23 and 24 are diagrams showing examples of the shape of the stringwork portion 2 and the dimensions of each portion.
As shown in FIG. 22, the speed and acceleration of Example 11 are shown by a quintic regression equation (more preferably, the regression coefficient is also displayed). When designing the stringwork portion 2, the angle θs shown in FIG. 24 or 90 degrees of the angle θs in FIG. 24, the length (LL 0 ) of the string portion 25 passing outside the pins 21 to 24 is calculated by “LL0 = 4 × (ee−bb) + π × ee”. be able to. In reverse calculation, the relationship among LL0, pin diameter bb, and angle θs is also determined. A method of performing a calculation using the length of the string portion 25 as an input using an inverse calculation formula and searching for a desired condition from a ternary calculation table of [LL0, ee, θs] may be used.

図２５は、紐細工部２の形状と各部寸法の一例を示す図である。
第１固定ピン２３の中心から紐細工部２の中心までの距離ｂと、第２連結ピン２２の中心から紐細工部２の中心までの距離ｃと、ピン径ｄｄが決まると紐部２５の長さが下記数５で計算でき、紐緒元表示は、[ｂ，ｃ，ｂｂ]と[ｄｄ，ｂｂ，θｓ]と[ＬＬ０，ｄｄ，θｓ]の三種が完成する。 FIG. 25 is a diagram illustrating an example of the shape of the stringwork portion 2 and the dimensions of each portion.
When the distance b from the center of the first fixing pin 23 to the center of the stringwork portion 2, the distance c from the center of the second connection pin 22 to the center of the stringwork portion 2, and the pin diameter dd are determined, The length can be calculated by the following equation (5), and three kinds of string display are completed: [b, c, bb], [ dd , bb, θ s ] and [LL0, dd, θ s ] .

図２６は、紐細工部２の形状の一例を示す図である。
紐細工部２は、図２６のピン２１〜２４とピン６１〜６４の８ピン構成で特性を得ることも可能である。
紐部２５が長く、弾性変形も大きくなる。ピン２１〜２４，６１〜６４をローラに変更して回転抵抗を削減すると更によい。 FIG. 26 is a diagram illustrating an example of the shape of the stringwork unit 2.
Cord craft unit 2, it is also possible to obtain a characteristic in 8-pin configuration of the pins 21 to 24 and pins 61 to 64 in FIG. 26.
The string part 25 is long and elastic deformation is also large. More preferably, the pins 21 to 24 and 61 to 64 are changed to rollers to reduce rotational resistance.

実施例１３の緒元[ｄｄ，ｂｂ，θｓ]から[ＬＬ０，ｄｄ，ｂ]を求めることができる。ｄｄが４個共通の場合の動きは、ｄｄ＝０で計算した結果を参照して決めることができる。すると、[ｂｂ、θｓ]を決めると、図２７から図２８が決まる。緒元から図２９の結果を得ることができる。 [LL0, dd, b] can be obtained from the specification [dd, bb, θs] in the thirteenth embodiment. The movement when four dds are common can be determined with reference to the result calculated with dd = 0. Then, when [bb, θs] is determined, FIGS. 27 to 28 are determined. The result of FIG. 29 can be obtained from the specifications.

図２９は、第１及び第２スライダ３，４の巾と回転部材２０の回転角度との関係を示す図である。縦軸は巾［ｍｍ］を示し、横軸は回転部材回転角度θ［ｄｅｇ］を示す。
図２９中に示したθが０度近くと９０度近くで二次回帰式から離れている。これは、速度変化が小さく良いことを示して滑らかな動き程、二次式から離れている。 FIG. 29 is a diagram showing the relationship between the widths of the first and second sliders 3 and 4 and the rotation angle of the rotating member 20. The vertical axis represents the width [mm], and the horizontal axis represents the rotating member rotation angle θ [deg].
It shows the θ is away from the quadratic regression equation with 0 degrees near 90 degrees near in Figure 29. This indicates that the speed change is small and good, and the smoother the movement, the farther from the quadratic equation.

同じデータを３次で回帰式した結果も図３０で示す。
寄与率Ｒ²も約１で良い回帰となっている。θが０度と９０度近くで離れが少なく、寄与率Ｒ²が略１となり、良い回帰ができた。
図２０〜図２２の５次回帰式と比較してシンプルであるが、近似的に滑らかな変化を表現していることが分かる。
二次関数と三次関数の差分が前述滑らかさを示す要素を含んでいる（本来は一次式との差である。）。 The result of regression of the same data in the third order is also shown in FIG .
The contribution rate R ^{2 is} also about 1 and is a good regression. When θ is 0 ° and close to 90 °, there is little separation, and the contribution rate R ² is approximately 1, so that a good regression has been achieved.
It is simpler than the quintic regression equation of FIGS. 20 to 22, but it can be seen that it expresses an approximately smooth change.
The difference between the quadratic function and the cubic function includes an element indicating the aforementioned smoothness (originally a difference from the linear expression).

この差分を特性値にした、滑らかさの検定も可能となる。
この差を特性値として滑らかさの評価関数を設けたロジックを設定して、円滑な設計支援を行う。
また、被測定物Ｗに応じた、種々の評価も加えると、部品毎の特殊な要求に対応できることも示す。
また、紐部２５の長さが必要に応じて伸びたり、輪ゴム７，８の力が紐に掛かって、弾性変形分の伸びが加わったりした時の対応も、従来技術内で種々の案があるので、その採否における検討も行うとよい。 It is also possible to test smoothness using this difference as a characteristic value.
The logic provided an evaluation function smoothness this difference as a characteristic value and setting, performing smooth design support.
In addition, when various evaluations according to the object to be measured W are added, it is shown that special requirements for each part can be met.
There are various proposals within the prior art for the case where the length of the string portion 25 is extended as necessary, or the elastic force of the rubber bands 7 and 8 is applied to the string and the elastic deformation is applied. Because there is, it is good to consider the adoption .
