Abstract
The invention discloses a flexible coupling module type blisk abrasive flow machining polishing clamp. The flexible coupling module type blisk abrasive flow machining polishing clamp comprises an upper flow distributing plate, an outer sleeve, a lower flow distributing plate, restraining modules, a center shaft and a locating pin. Each restraining module is composed of restraining sub-modules, wherein the number of the restraining sub-modules is identical with that of blades of the turbine blisk. Gap flow channels are formed between the restraining sub-modules and the blades of the turbine blisk. Each restraining sub-module on the corresponding gap flow channel and the surface of the corresponding blade of the turbine blisk are provided with coupled curved surface shapes. The sections, in the direction perpendicular to the curved surface of the blades, of the gap flow channels are identical and have the same width. In the polishing process, abrasive materials flow into the gap flow channels between the restraining sub-modules and the blades of the turbine blisk along a flow distributing channel of the upper flow distributing plate. Double layers of flow guide plates enable the abrasive materials to be continuous and stable when the abrasive materials enter the gap flow channels. In the abrasive flow machining polishing process, the inner surface of each gap flow channel which the abrasive materials pass through always keeps the same distance away from the surface of the corresponding blade, and the surface quality of the blades is guaranteed to be uniform. The combined clamping manner is adopted by the restraining modules, and turbine blisks of different types and sizes can be polished.
