Split baffle ring mounting device and split baffle ring mounting method

The invention discloses a split baffle ring mounting device and a split baffle ring mounting method, relates to the field of aero-engines, and aims to conveniently mount split baffle rings at blades of the aero-engines. The split baffle ring mounting device comprises a supporting seat, a driving disc, an abutting piece and a limiting piece. The support seat is configured to provide support. The driving disc is constructed to be in an Archimedes spiral shape, and the number of the driving disc is more than one circle; the driving disc is rotatably mounted on the supporting seat. The multiple abutting pieces are distributed in the circumferential direction of the driving disc, and the abutting pieces are installed on the driving disc. The limiting piece is installed on the supporting base and limits the moving path of the abutting pieces, so that the abutting pieces have the freedom degree of radial movement relative to the supporting base, damage to other parts caused by single-point knocking of the split baff
