Micro-rotor balancing measure swing frame

The present invention discloses a miniature measuring rotor balancing rocker, the rocker is a fixed rack provided in a rigid guide frame, the rack guide by the guide means cooperate with the supporting block in a linear direction of the horizontal swing of the support block, and between the frame and the support block is provided for preventing the supporting block rotatable around the swing direction in which the straight line of the rotation stopping structure, the elastic stopper means for the damping unit in the opposite sides of the swinging direction of said damper support block. The present invention thereby elastically supporting role to play existing rack replaced rigid rack, and rely on the rack guide support block moving to reduce the impact on the rigidity of the rack guide pivotable support block, increase overall swing frame when the micro sensitivity measuring dynamic imbalance of the rotor performance.
