When in use, the tool starting torque is first detected by a detection device, and after recording the torque value, the clamping member is 322 is fixedly assembled on the knife ring of the tool body 600 to ensure the fixation of the knife ring and the clamp 322. The speed and torque of the rocker arm 321 are set by the motor 311 controller, and the motor 311 is started. The gearbox 312 drives the rocker arm 321 to rotate, and the rotation of the rocker arm 321 drives the clamp 322 to rotate. The rotation of the clamp 322 drives the knife ring to rotate relative to the knife shaft for running-in, and observe whether the floating sealing ring of the tool is separated or falls off. After running-in to the set time, the motor 311 controller controls the motor 311 to stop rotating, removes the clamp 322 on the knife ring, and reuses the detection device to start the torque of the tool and compares it with that before running-in. If the data is consistent, it is qualified, thereby realizing mechanized detection of tool running-in, reducing labor costs, reducing running-in time, and thus improving running-in efficiency and detection quality.
