Preparation method of self-stabilization high-precision conductive thin-wall circular ring and processing clamp thereof

The invention discloses a self-stabilization high-precision conductive thin-wall circular ring preparation method and a machining clamp thereof. Centripetal arc angles are arranged on the two end faces of a conductive thin-wall circular ring and used for conductive contact, contact is kept on the outer circle of the circular ring, and a conductive area and a fixed keeping area are separated; in the preparation of the conductive thin-wall circular ring, the conductive thin-wall circular ring is firstly formed by adopting an aging-state TF00 C17200 beryllium bronze material, and the conductive thin-wall circular ring is placed on a ZrO2 ceramic mandrel to be subjected to solid solution and aging treatment, so that the machining residual stress is thoroughly removed, and the dimensional stability and precision of the conductive thin-wall circular ring are kept; in the forming process of the conductive thin-wall circular ring, the expansion core, the expansion shaft and the positioning sleeve are used for forming
