Dynamic torque detection system

The invention discloses a dynamic torque detection system, comprising a bench and a torque sensor; an electrical-pneumatic torque wrench is fixedly mounted on the bench; one end of the torque sensor is connected with an output shaft of the electrical-pneumatic torque wrench; the other end of the torque sensor is connected with a sleeve through a coupling; the sleeve is rotationally fixed on the bench and is connected with a torque brake device that may provide continuous braking for torque. By providing the torque brake device that may provide continuous braking for torque to detect a torque peak, measurement precision is improved; the torque brake device is arranged as a bolt, continuous braking is achieved by tightening the bolt; compared with simulated bolts, the dynamic torque detection system as a calibrator allows an actually used bolt to be sued in the detection process, and the actual condition can be simulated to maximum extent. 本发明公布了动态扭矩检测系统，包括机台和扭矩传感器，所述机台上固定安装有电、气动扭矩扳子，所述扭矩传感器的端通过联轴器与电、气动扭矩扳子的输出轴
