Claims

[Scope of utility model registration request]

In a tapping machine that processes a screw hole by attaching a tap or the like to a main shaft driven by a rotary drive mechanism, an elastic member is interposed in the rotational force transmitting part to the main shaft and fixed to both sides of the elastic member and the main shaft. A detector is installed to detect the presence or absence of an appropriate light-transmitting window formed on these rotating disks, and when twisting occurs in the elastic member during processing, the above-mentioned A phase difference is generated between the output signals of the detector through a transparent window formed on the rotating disk, and this phase difference signal and the output signal of the detector installed around the rotating disk fixed to the main shaft and the above. A torque detection device for a tapping board, characterized in that a control circuit processes a tap diameter setting double voltage, and controls the rotational state of an electric motor that is a drive source.
