Title:
力検出装置
Document Type and Number:
Japanese Patent JP4907050
Kind Code:
B2
Abstract:
Forces and moments are detected in a distinguishing manner by a simple structure. A supporting member (300) is positioned below a force receiving member (100), which receives forces to be detected, and between these components, at least two columnar force transmitting members (T1,T2) are connected. Connecting members having flexibility are interposed at the upper and lower ends of each of columnar force transmitting members so that columnar force transmitting members can become inclined when force receiving member becomes displaced upon receiving a force. Sensors (S1,S2) are positioned at the respective connection parts of columnar force transmitting members and supporting member to detect forces that are transmitted from the respective columnar force transmitting members (11,12) to supporting member (20). Based on the detection values of the sensors, a detection processing unit detects, in a distinguishing manner, forces and moments acting on force receiving member. When four columnar force transmitting members are used, all of forces Fx, Fy, and Fz and moments Mx, My, and Mz can be detected. Displacements are restricted by a corresponding part.
