WORKPIECE PRESSURE DEVICE, AND VIBRATION INSPECTION APPARATUS WITH THE SAME

PROBLEM TO BE SOLVED: To provide a workpiece pressure device which can securely detach a workpiece without a complex mechanism for attaching/detaching the workpiece to an arbor and can be a compact constitution, and a vibration inspection apparatus with the same.SOLUTION: A workpiece pressure device comprises: a pressure mechanism which pressures a workpiece W supported by an arbor 33 in the rotational axis direction of the arbor 33; and a workpiece removal mechanism which removes the workpiece W from the arbor 33. The pressure mechanism comprises: operation members 91, 121, 123 which transmit applied pressure to the workpiece W supported by the arbor 33; a first pressure drive part and a second pressure drive part which pressure the operation members 91, 121, 123; and a frame to which the first pressure drive part and the second pressure drive part are fixed. The second pressure drive part generates upward cancel force to decrease the supporting force for supporting the dead weight of the operation members 91, 121, 123 so as to perform a floating support of the operation members 91, 121, 123, and the workpiece removal mechanism downwardly pressures the operation members to scrape out the workpiece W supported by the arbor 33.SELECTED DRAWING: Figure 17 【課題】アーバへのワークを着脱する機構を複雑にすることなく、確実にワークの取り外しが行え、しかもコンパクトな構成にできるワーク加圧装置及び振動検査装置を提供する。【解決手段】ワーク加圧装置は、アーバ３３に支持されたワークＷをアーバ３３の回転軸方向に加圧する加圧機構と、ワークＷをアーバ３３から取り外すワーク取り外し機構とを備える。加圧機構は、アーバ３３に支持されたワークＷに加圧力を伝達する作動部材９１，１２１，１２３と、作動部材９１，１２１，１２３を加圧する第１、第２の加圧駆動部と、第１、第２の加圧駆動部が固定されるフレームとを有する。第２の加圧駆動部は作動部材９１，１２１，１２３の自重を支持するための支持力を軽減する上向きのキャンセル力を発生して作動部材９１，１２１，１２３をフローティング支持し、ワーク取り外し機構は作動部材を下向きに加圧してアーバ３３に支持されたワークＷを掻き出す。【選択図】図１７
