In the initial state, the first cylinder drives the movable clamper to leave the fixed clamper so as to make the distance between the fixed clamper and the movable clamper larger than the axial length of the worm workpiece to be processed; the second cylinder drives the upright drawing plate to slide along the guide rails on the rotary platform, so that the clamping position of the worm workpiece axially leaves the polishing rag wheel, and the third cylinder drives the support frame to slide along the longitudinal slide-rail, so that the upright drawing plate drives the clamping position of the worm workpiece to radially leave the polishing rag wheel; as shown in figure 1 and figure 2, in clamping, one end of the worm workpiece 27 to be processed is aligned to the fixed clamper, the first cylinder is started up to drive the movable clamper to fit with a clamper hole on the other end of the worm workpiece to be processed, so that the worm workpiece to be processed is clamped between the movable clamper and the fixed clamper; then the rag wheel drive motor is started up to drive the polishing rag wheel to rotate, the clamper drive motor drives the worm workpiece to be processed to rotate, the second cylinder drives the upright drawing plate to slide along the guide rails on the rotary platform and causes the worm workpiece to be processed axially closes to the circumference of the polishing rag wheel, the third cylinder further drives the support frame to slide along the longitudinal guide rail and causes the worm workpiece to be processed to contact with the circumference of the polishing rag wheel, and the axial feed motor drives the pedestal through the cooperation between the transverse screw rod and the second transmission nut on the pedestal to make the worm axially move, so that the worm is polished by the polishing rag wheel from one end to the other end; and the polishing operation to the worm is completed by repeating the above operation according to requirement of surface roughness level of the worm.
When a worm workpiece processing is finished, the worm workpiece is unloaded in recovered initial state, then a new worm workpiece to be processed is loaded, and the above operation is repeated.
