Abstract: The present invention discloses a servo-actuated support head having a magneto-rheological damping function. The servo-actuated support head comprises a pedestal; the intermediate position of the pedestal is provided with a central step through hole; the periphery of the central step through hole is provided with a plurality of circumferential step through holes; the left sides of the circumferential step through holes and the central step through hole are respectively provided with an internal thread; magneto rheological dampers are respectively assembled in the circumferential step through holes; each magneto rheological damper comprises a piston; a gap is disposed between each piston and the corresponding circumferential step through hole; each piston is provided with a groove; an excitation coil is wound in each groove; two ends of each piston are respectively connected with a left piston rod and a right piston rod; each piston rod is successively sleeved with springs, a magnet resistant ring and a sealing body in a direction from inside to outside of the corresponding circumferential step through hole; the right end of each right piston rod is connected with an auxiliary universal ball; a hexagon socket headless screw sleeves the left end of each left piston rod and is connected with the internal thread at the left side of the corresponding circumferential step through hole; and a main universal ball is fixedly connected to the right end of the central step through hole via a nut. By adoption of the support head, thin-wall part flutter can be effectively suppressed.
