Transverse stator blade assembling method and positioning tool

The invention discloses a transverse static blade assembling method and a positioning tool. The tool comprises a first check block and a pressing mechanism thereof, a tail check block and a pressing mechanism thereof, and a plurality of wedge-shaped filler strips. The head check block and the tail check block are used for limiting the circumferential installation positions of the head stator blade and the tail stator blade so as to guarantee that the circumferential installation positions of all the stator blades in the half circle are accurate, and the two pressing mechanisms are used for fixing the head check block and the tail check block to split faces at the two ends of the air cylinder respectively so as to fix all the stator blades in an installation groove of the air cylinder. The wedge-shaped filler strip is used for filling a gap between the outer arc of the crown of the stator blade and the outer circle of the cylinder mounting groove and limiting the radial position of the stator blade in the cyli
