Summary:The utility model relates to a tool spindle device of a numerical control spiral bevel gear milling machine. The tool spindle device of the numerical control spiral bevel gear milling machine comprises a spindle box and a tool spindle arranged in the spindle box. The tool spindle device of the numerical control spiral bevel gear milling machine is characterized in that a torque motor stator and a torque motor rotor are fixed inside the spindle box, the torque motor rotor is connected with the tool spindle through a taper sleeve and a key, one end of the tool spindle is provided with an encoder through a sleeve and a locking nut, and a damping mechanism which can exert a reverse force on the tool spindle is installed in the middle of the tool spindle. The tool spindle device of the numerical control spiral bevel gear milling machine has the advantages that the tool spindle is driven to rotate by a torque motor directly, the problems of transmission precision and transmission efficiency losses caused by cradle
