Centerless grinding type automatic polishing device for irregular workpiece

The utility model discloses a centerless grinding type automatic polishing device for irregular workpieces, which comprises a polishing wheel and a guide wheel which are oppositely arranged, and a cutter supporting frame which is arranged between the polishing wheel and the guide wheel and is used for supporting the workpieces, and the rotation direction of the guide wheel is the same as that of the polishing wheel. The grinding wheel is driven by a first air cylinder to move in the direction of the guide wheel, and a first telescopic piece is arranged between the grinding wheel and the first air cylinder. According to the scheme, in the polishing process, the spacing distance between the polishing wheel and the guide wheel is changed through the counter-acting force generated by the first telescopic part and the second telescopic part along with the shape change of the workpiece, so that the workpiece with the complex external shape is polished, meanwhile, the stability in the polishing process is improved b
