Tubular hardware grinding equipment

The utility model belongs to the technical field of hardware, particularly relates to tubular hardware polishing equipment, and aims to solve the problem that tubular hardware is easy to slip during polishing in the background technology, and adopts the following scheme that the tubular hardware polishing equipment comprises a base, and an inner ring fixing mechanism is arranged at the top of the base; and the inner ring fixing mechanism comprises a mounting plate arranged at the top of the base, a first servo motor mounted on the outer wall of the top of the mounting plate, and a bidirectional lead screw connected to the outer wall of an output shaft of the first servo motor through a coupler. The first servo motor drives the two-way lead screw to rotate, so that the two fixing pieces move in a centering mode, hardware bodies with different inner diameters can be fixed, the phenomenon that the hardware bodies slip in the polishing process is effectively avoided, stability is good, and practicability is high.
