PURPOSE: An apparatus for controlling output torque of a torque wrench is provided to prevent the shortage or wrong fastening of output torque during joining bolts since the time when output pressure of torque wrench reaches pre-set pressure is counted. CONSTITUTION: An apparatus for controlling output torque of a torque wrench comprises a torque measuring unit(20), an output torque determining unit(30), and a controller(50). When bolt is fastened up by a torque wrench, the torque measuring unit measures the output torque. The output torque determining unit determines whether an output torque value reaches a pre-set torque value. The controller controls the operation of the torque wrench based on the result of the output torque determining unit. . The controller stops bolt the fastening action of the torque wrench when the output torque value reaches the pre-set torque value. |
