Abstract
A clamp device is equipped with a clamp body, a piston rod, a link mechanism, a detection mechanism for detecting a state of rotary motion of a clamp arm, and a determination unit for determining whether a state of clamping exists. The detection mechanism includes a first proximity sensor, and a knuckle joint having a first sloped surface. The determination unit, on the basis of a comparison of an output signal from the first proximity sensor to a clamp threshold value, determines whether a state of clamping exists, and on the basis of a comparison to a clamping force generation threshold value, determines whether a state of generation of clamping force exists.
