Abstract: A bolt clamping force transducer for a bolt tightening operation is introduced to tighten a bolted joint by driving a torque rotating shaft in a clamping force transducer, such that a helical mechanism at one end of the torque rotating shaft generates an axial force for pressing a force sensing module and thus generates a strain value thereof. A socket is driven by the other end of the torque rotating shaft, thereby generating a clamping force under which the bolted joint of a specific specification is tightened. A parameter relation between the strain value and the clamping force is calibrated with a standard axial force gauge to facilitate calculation and control of the clamping force during the tightening process where the bolted joint fitted to any torque tool is sensed to control the precision of the clamping force being exerted on the bolted joint, thereby enhancing the quality thereof.
