Curved surface flexible polishing machine

The utility model discloses a flexible processing device of mechanical parts, in particular a curved surface flexible polishing machine used for finishing machining the curved surfaces of the mechanical parts. An electromotor (6) is arranged at the right side of a speed reducer (5), and is connected with a grinding wheel shaft sleeve (3) through a coupler, and a workpiece (1) is movably arranged in the grinding wheel shaft sleeve (3) and is movably connected with a flexible tire grinding wheel. Because an inflating tire grinding wheel is designed for the utility mode, the outer surface of the inner ring of an inflating tire is stuck with gravel, the rotating tire grinding wheel flexibly grind the curved-surface workpiece so as to grind the curved-surface wrokpiece smooth and reduce the noise. A sealed grinding space is formed by the grinding wheel shaft sleeve, and environment pollution is avoided. The curved surface flexible polishing machine has a simple structure and an obvious effect, the product quality
