Self-adaptive tool for annular rotary thin-wall part and flexible clamping method

The invention discloses a self-adaptive tool for an annular rotary thin-wall part and a flexible clamping method, and relates to the technical field of auxiliary machining of aerospace thin-wall parts. The self-adaptive tool comprises a mounting supporting unit and a self-adaptive adjustment clamping and supporting unit. The mounting supporting unit comprises a top cover, a base and a telescopic stand column. The self-adaptive adjustment clamping and supporting unit comprises a plurality of self-adaptive adjustment clamping and supporting structures. Each self-adaptive adjustment clamping and supporting structure comprises an upper sliding block, a telescopic rod, a bus supporting rod and a lower sliding block which are hinged in sequence, wherein the position of the upper sliding block on the top cover can be adjusted, the position of the lower sliding block on the base can be adjusted, and the bus supporting rod is used for supporting the inner wall of the annular rotary thin-wall part.
