る過負荷トルク検出装置。[Scope of Claim for Utility Model Registration] A tool holding cylinder is supported on a holder shaft with a predetermined play in the circumferential direction, and the two are connected by a torsion coil spring for transmitting torque, and a plurality of tool holding cylinders are provided on the tool holding cylinder. In a tool holder configured to detect a rotation delay of a detector with respect to a holder axis, the tool holder includes: a) a reference pulse generator that generates a reference pulse based on the spindle rotation angle or time; b) a reference signal generator in the spindle rotation direction; c) the above-mentioned. a detection switch that detects the detector, d a counter that counts the reference pulses from the reference signal output of the reference signal generator during one rotation of the spindle, e a counter that is read out at the output timing of the detection signal of the detection switch; A comparison circuit that compares the numerical value with a preset reference value corresponding to each detector; and f an output circuit that outputs an overload torque detection signal based on the comparison result. Overload torque detection device in tool holder.
