  • Patent number: 11951581
    Abstract: Provided is a clamp system with enhanced functionality achieved by detecting the behavior of an object to be clamped, using a stroke-end position detector that has been used for switching stroke operations. A clamp device 1 has an output member 12 which executes a stroke movement causing a change in the distance by which a coil 15 is inserted into a hole 14 having a bottom. A converter 23 outputs a measurement value of the inductance of the coil 15. The inductance of the coil 15 when a work W has been clamped by the output member 12 is stored in a work clamp point memory 22e, and a clamp area indicating a variation range permitted with respect to a work clamp point is set in a clamp area memory. During processing of the work, a control unit 2 measures the inductance of the coil 15, determines whether the work clamp point is within the range of the clamp area, and, if the range is exceeded, issues a signal indicating an emergency stop.
