Dynamic balancing machine calibration device

The utility model discloses a dynamic balancing machine calibration device, which relates to the technical field of dynamic balancing machines and comprises a base and a sliding seat, the sliding seat is assembled in the base, and two groups of fixed seats are fixedly mounted on the sliding seat. According to the dynamic balancing machine calibration device, through cooperative use of the base, the movable roller, the sliding seat and the movable threaded rod, the dynamic balancing machine calibration device is calibrated and assembled on the sliding seat, a cavity is formed in the sliding seat to reduce the self weight, and when the overall position of the sliding seat needs to be adjusted to drive the calibration device to move, the calibration device is convenient to move. The servo motor can drive the movable threaded rod to integrally rotate and move through the driving shaft of the servo motor, then the sliding base is pushed to slide in the base through threads on the outer side of the movable threaded
