Abstract

The application discloses a valve rod outer surface polishing equipment and a using method, which comprises an upper center for fixing the valve rod and a lower fixing structure for fixing the valve rod in cooperation with the upper center, a polishing part for polishing the valve rod is arranged between the upper center and the lower fixing structure, the upper center and the lower fixing structure are both installed on a fixing frame, the lower fixing structure comprises a lower center for tightly pressing the bottom of the valve rod, and a fixing part for fixing the valve rod in cooperation with the threaded position of the valve rod is arranged on the lower center, the nut is rotated on the threaded rod, so that the height of the nut is increased, the length of the connecting rod is a fixed value, so the distance from the sliding shaft to the nut is unchanged and only the height is changed, so that the inclination angle of the sliding frame can be adjusted through the sliding shaft to adapt to valve rods with different diameters, and the application range of the equipment is wider, the clamping position of the equipment is located at the threaded position of the valve rod, so that the surface polishing of the valve rod can be more comprehensive, and secondary clamping is avoided.
