Aiming at the circuit processing and mechanical process of the five station automatic rotor balancing machine,the improvement of cutting machining accuracy is studied.The tool setting signal processing circuit of the fully automatic balancing machine is adopted,and the vibration signal is passed through the low-pass filter,rectifier circuit,envelope detection circuit and comparison circuit to obtain a reliable tool setting signal,which can adapt to the continuous production of the fully automatic balancing machine with high beat,reducing the requirements for maintenance and machine adjustment;the automatic clamping steering mechanism is improved,and the positioning support rod and sensor are added in the clamping rotating device,which improves the clamping rotation accuracy,further improves the rotor cutting and weight removal accuracy,and reduces the imbalance of the rotor processing.The processing effect shows that the unbalance and weight removal effect of the five station automatic rotor balancing machine can be reduced from 12 mg to 5 mg,effectively improving the machining accuracy.
