この試験装置1は、防振器取付部2bに防振器Sの第1の支持部材S1を固定し、引き手17を防振器Sの第2の支持部材S2に連結して使用する。防振器取付部2bは、枠片18の長孔18a内で支持棒20を移動させて、防振器Sの大径部を四本の支持棒20内に配置し、支持棒20周りに結束バンド22を巻き付け結束し、防振器Sの大径部を第1挟持片19の凹部19aに嵌合させると共に、止めナット23を締め込み第2挟持片21と第1挟持片19とで防振器Sの大径部を挟み込んで固定する。防振器Sは、大径部の一端を第1挟持片19の凹部19aに嵌合させれば、試験装置本体7の軸線上に配置される。防振器Sの径がより小さい場合には、第1挟持片19の他方の凹部19bを使用したり、複数種類のリング状治具25,26から合致するものを一つ選択して凹部19a,19bに嵌め込んだり、枠片18に固定した開口付き治具24を使用したり、複数種類のリング状治具25,26から合致するものを一つ選択して凹部24bに嵌め込んで、防振器Sの大径部を受けることとする。   This test apparatus 1 is used by fixing the first support member S1 of the vibration isolator S to the vibration isolator mounting portion 2b, and connecting the handle 17 to the second support member S2 of the vibration isolator S. The vibration isolator mounting portion 2 b moves the support rod 20 within the elongated hole 18 a of the frame piece 18, arranges the large diameter portion of the vibration isolator S within the four support rods 20, and surrounds the support rod 20. The binding band 22 is wound and bound, and the large-diameter portion of the vibration isolator S is fitted into the recess 19 a of the first sandwiching piece 19, and the locking nut 23 is tightened to connect the second sandwiching piece 21 and the first sandwiching piece 19. The large-diameter portion of the vibration isolator S is sandwiched and fixed. The vibration isolator S is disposed on the axis of the test apparatus main body 7 if one end of the large diameter portion is fitted into the recess 19 a of the first holding piece 19. When the diameter of the vibration isolator S is smaller, the other concave portion 19b of the first clamping piece 19 is used, or one that matches from a plurality of types of ring-shaped jigs 25 and 26 is selected and the concave portion 19a is selected. , 19b, using a jig 24 with an opening fixed to the frame piece 18, or selecting one that matches from a plurality of types of ring-shaped jigs 25, 26 and fitting it into the recess 24b, The large diameter part of the vibration isolator S is received.

本体ユニット5は、防振器取付部4に固定された防振器Sのストロークのほぼ中間位置に引き出した第2の支持部材S2に引き手17を連結するように、ブラケット8の取付位置を調整孔3aにより調整してボルト8a及びナット8bで固定する。   The main unit 5 has the mounting position of the bracket 8 so that the puller 17 is connected to the second support member S2 pulled out to an approximately middle position of the stroke of the vibration isolator S fixed to the vibration isolator mounting portion 4.

この状態でモータ11を正逆回転させて回転軸13を回転させると、回転軸13に螺合するナット体14が軸線方向に相対移動し、ケース10に対して摺動杆15を伸縮変位させる。これに伴う第1の支持部材S1と第2の支持部材S2との伸縮速度はモータ11に付設されたエンコーダ12により、また伸縮のストローク端はリミットスイッチ7aにより、さらに伸縮動に伴う荷重の大きさはロードセル16によって夫々検知され、図示しない出力装置に記録、出力される。本体7と防振器Sとの軸線は一致しており、その軸線上にロードセル16が位置するため、モーメントが作用することなく防振器Sにかかる荷重を正確に測定できる。   In this state, when the motor 11 is rotated forward and backward to rotate the rotating shaft 13, the nut body 14 screwed to the rotating shaft 13 moves relative to the axial direction, and the sliding rod 15 is expanded and contracted with respect to the case 10. . The expansion / contraction speed between the first support member S1 and the second support member S2 is increased by the encoder 12 attached to the motor 11, the expansion / contraction stroke end is further controlled by the limit switch 7a, and the load accompanying the expansion / contraction movement is increased. This is detected by the load cell 16 and recorded and output to an output device (not shown). Since the axes of the main body 7 and the vibration isolator S coincide with each other, and the load cell 16 is positioned on the axis, the load applied to the vibration isolator S can be accurately measured without applying a moment.

本発明は、防振器の伸縮動の軸線上にロードセルを配置して、作動試験の測定精度を高める試験装置である。   The present invention is a test apparatus in which a load cell is arranged on the axis of expansion and contraction motion of a vibration isolator to increase the measurement accuracy of an operation test.
