回転軸１３は、一対設けられ、載置部１１を脚部１２に対して回転可能に支持する役割を果たす。この回転軸１３は、図１及び図２に示すように、水平方向に延び、その軸方向一端部が載置部１１の側部に固定されると共に、軸方向他端部が脚部１２の柱部材２９によって回転可能に支持されている。なお、載置部１１を回転可能に支持する態様としては、本実施形態に代えて、水平方向に延びる回転軸１３の軸方向一端部が脚部１２の柱部材２９に固定されると共に、軸方向他端部が載置部１１の側部によって回転可能に支持されてもよい。 A pair of rotating shafts 13 are provided and serve to rotatably support the mounting portion 11 with respect to the leg portion 12. As shown in FIGS. 1 and 2, the rotating shaft 13 extends in the horizontal direction, one end in the axial direction is fixed to the side portion of the mounting portion 11, and the other end in the axial direction is the leg portion 12. It is rotatably supported by the pillar member 29. As a mode for rotatably supporting the mounting portion 11, instead of the present embodiment, one end portion in the axial direction of the rotating shaft 13 extending in the horizontal direction is fixed to the pillar member 29 of the leg portion 12, and the shaft The other end in the direction may be rotatably supported by the side portion of the mounting portion 11.

ストッパー１４は、ワークＷを測定する時の測定位置を越えて載置部１１が回転するのを規制する役割を果たす。このストッパー１４は、図１に示すように、六角ボルト３２と、この六角ボルト３２の軸部に螺合される一対のナット３３とを有している。このように構成されるストッパー１４は、脚部１２を構成するストッパー設置部材３１の上面に、上方へ突出するようにして取り付けられる。より詳細には、ストッパー１４は、ストッパー設置部材３１に形成されたボルト挿通穴（不図示）に対して六角ボルト３２が挿通されると共に、一対のナット３３が締め付けられてその間にストッパー設置部材３１を挟み込むことにより、ストッパー設置部材３１に取り付けられる。この時、ストッパー１４のストッパー設置部材３１からの突出高さは、載置部１１が図２及び図５に示す測定位置Ｐにある状態、すなわち回転軸１３を中心として時計回りに略９０°回転した状態における載置部１１の底面と脚部１２の上面との離間距離に略等しい大きさに設定されている。なお、本実施形態ではストッパー１４をストッパー設置部材３１の上面に上方へ突出するようにして取り付けたが、これに代えて、ストッパー１４を載置部１１の底面に下方へ突出するようにして取り付けてもよい。 The stopper 14 plays a role of restricting the rotation of the mounting portion 11 beyond the measurement position when measuring the work W. As shown in FIG. 1, the stopper 14 has a hexagon bolt 32 and a pair of nuts 33 screwed into the shaft portion of the hexagon bolt 32. The stopper 14 configured in this way is attached to the upper surface of the stopper installation member 31 constituting the leg portion 12 so as to project upward. More specifically, in the stopper 14, the hexagon bolt 32 is inserted into a bolt insertion hole (not shown) formed in the stopper installation member 31, and a pair of nuts 33 are tightened between them. Is attached to the stopper installation member 31 by sandwiching the. At this time, the protruding height of the stopper 14 from the stopper installation member 31 is such that the mounting portion 11 is at the measurement position P shown in FIGS. 2 and 5, that is, the stopper 14 is rotated clockwise by approximately 90 ° around the rotation shaft 13. The size is set to be substantially equal to the distance between the bottom surface of the mounting portion 11 and the top surface of the leg portion 12 in the mounted state. In the present embodiment, the stopper 14 is attached so as to project upward on the upper surface of the stopper installation member 31, but instead, the stopper 14 is attached so as to project downward on the bottom surface of the mounting portion 11. You may.

衝撃吸収部材１５は、載置部１１が回転して図５に示す測定位置Ｐに達する際の衝撃を吸収する役割を果たす。この衝撃吸収部材１５は、公知のいわゆるショックアブゾーバであって、バネの弾性力や流体の圧力等によって衝撃を緩和するよう構成されている。この衝撃吸収部材１５は、図１に示すように、脚部１２を構成するストッパー設置部材３１の上面においてストッパー１４よりも若干外側の位置に、上方へ突出するようにして取り付けられている。また、衝撃吸収部材１５のストッパー設置部材３１からの突出高さは、ストッパー１４のストッパー設置部材３１からの突出高さより若干大きく設定されている。これにより、回転軸１３を中心として回転する載置部１１は、ストッパー１４に接触する直前に衝撃吸収部材１５に接触してその回転速度が低下することにより、ストッパー１４に接触する際の衝撃が緩和される。なお、本実施形態では衝撃吸収部材１５をストッパー設置部材３１の上面に上方へ突出するようにして取り付けたが、これに代えて、衝撃吸収部材１５を載置部１１の底面に下方へ突出するようにして取り付けてもよい。なお、衝撃吸収部材１５の種類や個数や設置場所は、本実施形態に限定されず適宜設計変更が可能である。 The shock absorbing member 15 plays a role of absorbing the shock when the mounting portion 11 rotates and reaches the measurement position P shown in FIG. The shock absorbing member 15 is a known so-called shock absorber, and is configured to absorb a shock by the elastic force of a spring, the pressure of a fluid, or the like. As shown in FIG. 1, the shock absorbing member 15 is attached to the upper surface of the stopper installing member 31 constituting the leg portion 12 at a position slightly outside the stopper 14 so as to project upward. Further, the protruding height of the shock absorbing member 15 from the stopper installing member 31 is set to be slightly larger than the protruding height of the stopper 14 from the stopper installing member 31. As a result, the mounting portion 11 that rotates about the rotation shaft 13 comes into contact with the shock absorbing member 15 immediately before it comes into contact with the stopper 14, and the rotation speed thereof decreases, so that the impact when contacting the stopper 14 is generated. It will be relaxed. In the present embodiment, the shock absorbing member 15 is attached so as to project upward on the upper surface of the stopper installation member 31, but instead of this, the shock absorbing member 15 projects downward to the bottom surface of the mounting portion 11. It may be attached in this way. The type, number, and installation location of the shock absorbing member 15 are not limited to this embodiment, and the design can be changed as appropriate.

付勢部材１６は、載置部１１を付勢する役割を果たす。この付勢部材１６は、公知のいわゆるダンパーであって、バネの弾性力や流体の圧力等によって対象物を付勢するよう構成されている。この付勢部材１６は、その長手方向に伸縮可能に構成され、図１に示すように、その上端部が載置部１１の底面に回動可能に固定される一方、その下端部が梁部材３０に回動可能に固定されている。これにより、付勢部材１６は、載置部１１を図５に示す測定位置Ｐに向けて図１の時計回りに付勢している。なお、付勢部材１６の種類や個数や設置場所は、本実施形態に限定されず適宜設計変更が可能である。 The urging member 16 serves to urge the mounting portion 11. The urging member 16 is a known so-called damper, and is configured to urge an object by the elastic force of a spring, the pressure of a fluid, or the like. The urging member 16 is configured to be expandable and contractible in the longitudinal direction thereof, and as shown in FIG. 1, the upper end portion thereof is rotatably fixed to the bottom surface of the mounting portion 11, while the lower end portion thereof is a beam member. It is rotatably fixed to 30. As a result, the urging member 16 urges the mounting portion 11 clockwise toward the measurement position P shown in FIG. The type, number, and installation location of the urging member 16 are not limited to this embodiment, and the design can be changed as appropriate.

保持部材１７は、付勢部材１６の付勢力に抗して載置部１１を水平状態で保持する役割を果たす。この保持部材１７は、図１に示すように、載置部１１から側方へ突出して設けられた係合ピン３４と、この係合ピン３４に係合可能な形状を有し、柱部材２９の上端部に回動可能に取り付けられた係合フック３５とを有している。そして、このように構成される保持部材１７によれば、係合フック３５を係合ピン３４に係合させれば、付勢部材１６から受ける付勢力に抗して載置部１１を水平状態で保持することができる。一方、係合フック３５を図１に示す状態から反時計回りに回動させることにより、係合フック３５と係合ピン３４との係合を解除すれば、載置部１１を回転軸１３の周りに自在に回転させることができる。 The holding member 17 serves to hold the mounting portion 11 in a horizontal state against the urging force of the urging member 16. As shown in FIG. 1, the holding member 17 has an engaging pin 34 provided so as to project laterally from the mounting portion 11 and a shape capable of engaging with the engaging pin 34, and the pillar member 29. It has an engaging hook 35 rotatably attached to the upper end portion of the above. Then, according to the holding member 17 configured in this way, when the engaging hook 35 is engaged with the engaging pin 34, the mounting portion 11 is placed in a horizontal state against the urging force received from the urging member 16. Can be held at. On the other hand, if the engaging hook 35 is disengaged from the engaging pin 34 by rotating the engaging hook 35 counterclockwise from the state shown in FIG. 1, the mounting portion 11 can be moved to the rotating shaft 13. It can be freely rotated around.

（ワーク測定手順及び作用効果）
次に、ワーク測定台１０を使用したワーク測定手順及びその作用効果について説明する。図４及び図５は、ワーク測定台１０を使用したワーク測定手順を説明するための概略正面図である。ワークＷの所定部位を測定しようとする測定者は、まず、図１に示すように、ワーク測定台１０を構成する載置部１１を水平状態にする。すなわち、手で載置部１１を押圧することにより、付勢部材１６の付勢力に抗して載置部１１を水平状態にする。そして、保持部材１７を構成する係合フック３５を係合ピン３４に係合させる。これにより、付勢部材１６から作用する付勢力に拘わらず、載置部１１は水平状態で保持される。 (Work measurement procedure and action effect)
Next, a work measuring procedure using the work measuring table 10 and its action and effect will be described. 4 and 5 are schematic front views for explaining a work measuring procedure using the work measuring table 10. A measurer who intends to measure a predetermined portion of the work W first sets the mounting portion 11 constituting the work measuring table 10 in a horizontal state as shown in FIG. That is, by pressing the mounting portion 11 by hand, the mounting portion 11 is brought into a horizontal state against the urging force of the urging member 16. Then, the engaging hook 35 constituting the holding member 17 is engaged with the engaging pin 34. As a result, the mounting portion 11 is held in a horizontal state regardless of the urging force acting from the urging member 16.

次に、ワーク測定台１０の上にワークＷを載置する。すなわち、ホイスト（不図示）等を使用して測定対象であるワークＷを吊り上げた後、そのワークＷをワーク測定台１０の載置部１１の上に降ろす。この時、前述のように載置部１１に設けられたワーク支持部材１９を構成する樹脂プレート２１がワークＷに接触するので、ワークＷの損傷が防止される。また、前述のようにワーク支持部材１９を構成する金属プレート２２の幅方向両側部に一対の脱落防止部材２４が設けられ、この一対の脱落防止部材２４がワークＷの両側方にそれぞれ位置しているので、ワークＷの脱落が防止される。なお、本実施形態で測定対象となるワークＷは、図１に示すように略円柱形状を有し、その先端側が若干小径となっている。 Next, the work W is placed on the work measuring table 10. That is, after lifting the work W to be measured using a hoist (not shown) or the like, the work W is lowered onto the mounting portion 11 of the work measuring table 10. At this time, since the resin plate 21 constituting the work support member 19 provided on the mounting portion 11 comes into contact with the work W as described above, damage to the work W is prevented. Further, as described above, a pair of fall prevention members 24 are provided on both sides of the metal plate 22 constituting the work support member 19 in the width direction, and the pair of fall prevention members 24 are located on both sides of the work W. Therefore, the work W is prevented from falling off. As shown in FIG. 1, the work W to be measured in the present embodiment has a substantially cylindrical shape, and the tip side thereof has a slightly smaller diameter.

次に、保持部材１７の係合を解除する。すなわち、図１に示す状態から保持部材１７の係合フック３５を反時計回りに回すことにより、図４に示すように係合フック３５と係合ピン３４との係合を解除する。これにより、保持部材１７による保持力から解放された載置部１１は、付勢部材１６から作用する付勢力によって時計回りに若干回転し、脚部１２の頂部から若干浮き上がった状態になる。 Next, the holding member 17 is disengaged. That is, by turning the engaging hook 35 of the holding member 17 counterclockwise from the state shown in FIG. 1, the engagement between the engaging hook 35 and the engaging pin 34 is released as shown in FIG. As a result, the mounting portion 11 released from the holding force by the holding member 17 is slightly rotated clockwise by the urging force acting from the urging member 16, and is slightly lifted from the top of the leg portion 12.

次に、載置部１１を図５に示す測定位置Ｐに向けて回転させる。すなわち、載置部１１の両側部に設けられた把持部材１８を把持し、図４に示すように、載置部１１を上方へ持ち上げるようにして回転軸１３の周りに時計回りに回転させる。この時、前述のように載置部１１は付勢部材１６によって時計回りに付勢されており、この付勢力を回転の補助として利用できるので、測定者は載置部１１を容易に回転させることができる。そして、前述のように付勢部材１６は伸縮可能に構成され、その上端部が載置部１１の底面にその下端部が梁部材３０にそれぞれ回動可能に固定されている。従って、載置部１１の回転に伴って、付勢部材１６は載置部１１及び梁部材３０に対する傾斜角度を変化させながら、載置部１１と梁部材３０の離間距離の変化増大に応じて伸縮伸長する。なお、載置部１１の回転に伴い、その上に載置されたワークＷは、その先端側を上にするようにして徐々に起き上がっていく。 Next, the mounting portion 11 is rotated toward the measurement position P shown in FIG. That is, the gripping members 18 provided on both sides of the mounting portion 11 are gripped, and as shown in FIG. 4, the mounting portion 11 is lifted upward and rotated clockwise around the rotation shaft 13. At this time, as described above, the mounting portion 11 is urged clockwise by the urging member 16, and this urging force can be used as an auxiliary for rotation, so that the measurer can easily rotate the mounting portion 11. be able to. As described above, the urging member 16 is configured to be expandable and contractible, and its upper end is rotatably fixed to the bottom surface of the mounting portion 11 and its lower end is rotatably fixed to the beam member 30. Therefore, as the mounting portion 11 rotates, the urging member 16 changes the inclination angle with respect to the mounting portion 11 and the beam member 30, and responds to an increase in the change in the separation distance between the mounting portion 11 and the beam member 30. Stretches and stretches. As the mounting portion 11 rotates, the work W mounted on the mounting portion 11 gradually rises with its tip side facing up.

その後、載置部１１が更に回転して図５に示す測定位置Ｐの直前に達すると、ストッパー設置部材３１に設けられたショックアブゾーバに対し、載置部１１の底面が接触する。これにより、載置部１１の回転速度が低下する。そして、載置部１１が更に回転して図５に示す測定位置Ｐに到達すると、ストッパー１４を構成する六角ボルト３２に対し、載置部１１の底面が接触する。これにより、載置部１１が測定位置Ｐを越えて更に時計回りに回転することが規制される。そしてこの時、図５に示すように、ワークＷはその先端側を上に向けるようにして鉛直に起立した状態になる。 After that, when the mounting portion 11 further rotates and reaches immediately before the measurement position P shown in FIG. 5, the bottom surface of the mounting portion 11 comes into contact with the shock absorber provided on the stopper installation member 31. As a result, the rotation speed of the mounting portion 11 decreases. Then, when the mounting portion 11 further rotates and reaches the measurement position P shown in FIG. 5, the bottom surface of the mounting portion 11 comes into contact with the hexagon bolt 32 constituting the stopper 14. As a result, the mounting portion 11 is restricted from rotating further clockwise beyond the measurement position P. At this time, as shown in FIG. 5, the work W is in a vertically standing state with its tip side facing upward.

この状態において、ワークＷの測定を行う。本実施形態では、図に詳細は示さないが、ワークＷの先端部に形成されたスプラインの寸法をいわゆるオーバーピン法によって測定することにより、スプラインが正しい形状に作製されているかどうかを確認する。このオーバーピン法では、スプラインの歯溝に対して２本の円柱状のピンをそれぞれ押し込み、その状態でマイクロメータを使用して２本のピンの離間距離を測定する。この時、ワークＷがその先端側を上に向けるようにして鉛直に起立しているので、２本のピンを押さえながらマイクロメータを水平に持った状態、すなわちマイクロメータの正確な使用方法によってピンの離間距離を正確に測定することができる。これに対し、もしワークＷが図１に示すように横倒しになっている状態でオーバーピン法による測定を行おうとすると、２本のピンの離間距離を測定する際にマイクロメータを垂直に立てた状態で手に持つ必要があるため、マイクロメータを正確な使用方法で用いることができない。 In this state, the work W is measured. In the present embodiment, although details are not shown in the figure, it is confirmed whether or not the spline is manufactured in the correct shape by measuring the size of the spline formed at the tip of the work W by the so-called overpin method. In this overpin method, two columnar pins are pushed into the tooth grooves of the spline, and the distance between the two pins is measured using a micrometer in that state. At this time, since the work W stands vertically with its tip side facing upward, the pin is held horizontally while holding the two pins, that is, the pin depends on the correct usage of the micrometer. The separation distance can be measured accurately. On the other hand, if the work W is laid on its side as shown in FIG. 1 and the measurement is performed by the overpin method, the micrometer is set up vertically when measuring the separation distance between the two pins. The micrometer cannot be used accurately because it must be held in the hand.

ワークＷの測定が完了すると、載置部１１を図１に示す水平状態に向けて回転させる。すなわち、載置部１１の両側部に設けられた把持部材１８を把持し、図４に示すように、載置部１１を押し倒すようにして回転軸１３の周りに反時計回りに回転させる。そして、載置部１１が図１に示す水平状態に近付くと、載置部１１と梁部材３０との間に介在された付勢部材１６がショックアブゾーバとしての役割を果たすことにより、載置部１１の回転速度が低下する。これにより、載置部１１が水平状態に戻る際の衝撃が緩和され、ワークＷの損傷が防止される。 When the measurement of the work W is completed, the mounting portion 11 is rotated toward the horizontal state shown in FIG. That is, the gripping members 18 provided on both sides of the mounting portion 11 are gripped, and as shown in FIG. 4, the mounting portion 11 is pushed down and rotated counterclockwise around the rotation shaft 13. Then, when the mounting portion 11 approaches the horizontal state shown in FIG. 1, the urging member 16 interposed between the mounting portion 11 and the beam member 30 acts as a shock absorber, thereby mounting the mounting portion 11. The rotation speed of the unit 11 decreases. As a result, the impact when the mounting portion 11 returns to the horizontal state is alleviated, and damage to the work W is prevented.

最後に、保持部材１７で載置部１１を水平状態に保持する。すなわち、付勢部材１６の付勢力に抗して載置部１１を手で押圧することにより、載置部１１を図１に示す水平状態とする。そして、この状態において保持部材１７を構成する係合フック３５を係合ピン３４に係合させる。これにより、付勢部材１６の付勢力に抗して載置部１１が水平状態で保持される。その後、ホイスト（不図示）等を使用してワークＷを水平状態で吊り上げ、所定の場所へ移動させる。以上により、ワークＷの測定作業が完了する。 Finally, the holding member 17 holds the mounting portion 11 in a horizontal state. That is, by manually pressing the mounting portion 11 against the urging force of the urging member 16, the mounting portion 11 is brought into the horizontal state shown in FIG. Then, in this state, the engaging hook 35 constituting the holding member 17 is engaged with the engaging pin 34. As a result, the mounting portion 11 is held in a horizontal state against the urging force of the urging member 16. After that, the work W is lifted in a horizontal state using a hoist (not shown) or the like and moved to a predetermined place. With the above, the measurement work of the work W is completed.

図６は、本発明の他の実施形態に係るワーク測定台４０を示す概略左側面図である。本実施形態のワーク測定台４０は、図１及び図２に示す実施形態のワーク測定台１０と比較すると、載置部４１がクランプ装置４２を備える点で相違している。それ以外の構成については図１及び図２に示す実施形態と同じであるため、図６では図１及び図２と同じ符号を付し、ここでは説明を省略する。 FIG. 6 is a schematic left side view showing a work measuring table 40 according to another embodiment of the present invention. The work measuring table 40 of the present embodiment is different from the work measuring table 10 of the embodiment shown in FIGS. 1 and 2 in that the mounting portion 41 includes the clamp device 42. Since the other configurations are the same as those shown in FIGS. 1 and 2, the same reference numerals as those in FIGS. 1 and 2 are given in FIG. 6, and the description thereof will be omitted here.

クランプ装置４２は、図６に示すように、操作レバー４３と、この操作レバー４３に接続されたリンク機構４４と、リンク機構４４の先端部に取り付けられた押圧部材４５と、を有している。このように構成されるリンク機構４４によれば、載置部４１の上にワークＷが載置されていない時は、図６に二点鎖線で示すように、操作レバー４３を倒伏した状態にすることにより、押圧部材４５を上方に持ち上げた状態にしておく。一方、載置部４１の上にワークＷを載置した時は、図６に実線で示すように、操作レバー４３を回動させて起立した状態にすることにより、押圧部材４５でワークＷの頂部を下方に向けて押圧する。これにより、載置部４１を回転させる際にワークＷが載置部４１から脱落することを防止することができる。 As shown in FIG. 6, the clamp device 42 has an operation lever 43, a link mechanism 44 connected to the operation lever 43, and a pressing member 45 attached to a tip end portion of the link mechanism 44. .. According to the link mechanism 44 configured in this way, when the work W is not mounted on the mounting portion 41, the operating lever 43 is in a state of being laid down as shown by the alternate long and short dash line in FIG. By doing so, the pressing member 45 is kept in a state of being lifted upward. On the other hand, when the work W is placed on the mounting portion 41, as shown by the solid line in FIG. 6, the operating lever 43 is rotated to bring the work W into an upright state, so that the pressing member 45 can hold the work W. Press the top downwards. As a result, it is possible to prevent the work W from falling off from the mounting portion 41 when the mounting portion 41 is rotated.
