Detection equipment and detection method for automatically measuring rotational rigidity of flexible shaft

The invention belongs to the field of precision machining and testing, and relates to a detection device and method for automatically measuring the rotational rigidity of a flexible shaft, and the device comprises a pedestal, a displacement measurement device, a lever assembly, a steering fixed seat, a measured workpiece, and a computer. The displacement measuring device and the steering fixing seat are arranged on the base in parallel; the lever assembly is arranged on a tested workpiece in a penetrating mode. A tested workpiece is arranged on the steering fixing seat; the steering fixing seat drives the tested workpiece to turn over by 90 degrees; the displacement measuring device is used for measuring the displacement change condition of the measured workpiece before and after the weight changes; the displacement measuring device is connected with the computer. The invention provides the detection equipment and the detection method for automatically measuring the rotational rigidity of the flexible shaft,
