Embodiment
[0063] Example: such as figure 1 Shown, including dynamic balance device, motion control system, data wireless transmission system, dynamic unbalance detection and calculation system, control decision calculation system and industrial computer;
[0064] The dynamic balancing device is placed in the main shaft 19. When working, the mass eccentricity is generated by the two sets of concentric and parallel mass blocks. When the main shaft 19 rotates, the dynamic unbalance force generated by the mass eccentricity is at the same position as that of the main shaft 19 itself. The dynamic balance force of equal magnitude and opposite direction can perform online correction of the dynamic imbalance of the spindle 19;
[0065] The dynamic unbalance detection and calculation system detects the unbalance signal of the spindle, analyzes the characteristics of the spindle dynamic unbalance according to the signal, and calculates the equivalent centrifugal force of the spindle dynamic unbalance an...
