DEVICE FOR POLISHING THE BLANK FACES Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: device has a grinding wheel fastened on a spindle, a multistation drum with the mechanism for the blank fastening, with the drum being mounted on the housing for rotating, and an assembly for the blank withdrawal from the processing area, with the assembly being made as a bunker located under the unloading site. The mechanisms for the blank fastening are made in the form of feeler mechanisms located on the concentric circles of the drum and spring-loaded balance beams. A roller designed to interact with the corresponding feeler mechanism is mounted on one end of each balance beam. The other end is made as a sector and is designed to contact with the blank. The blank is made with a vertical rotation axle and nests for the blank installation. The feeler mechanisms are located on the sites of the blank loading and unloading. EFFECT: enhanced quality of trimming the blank outer surfaces (faces) in polishing machines. 1 cl, 6 dwg
