Abstract
PURPOSE: To prevent occurrence of the imperfectly clamped products and thus to enhance the working efficiency by driving the nut runner while monitoring the clamping torque and then clamping the bolt, nut and others with a proper torque.
CONSTITUTION: When the air is supplied to the nut runner to perform clamping of the bolt, nut and others, the output of distortion gauge 1 varies in accordance with the clamping torque. The output then undergoes A/D conversion 5 via S/H3 and is then drawn into computer 8. And when the output of S/H3 becomes larger than the output of control level setter 10, electromagnetic valve 12 and other are actuated to cut of the air supply to the nut runner. In this case, if the A/D conversion output is lower than the allowance level rage of level setter 7, the level of setter 10 is altered. Thus the operation of valve 12 and others is stopped. And the air is supplied again to the nut runner. With repetition of this action, the clamping torque can always be kept within the allowance level range.
