The invention discloses a measuring tool and method for measuring the angle of a rectifying blade with a positioning pin. The measuring tool mainly consists of a base, a pressing rod, a nut, a bolt, a vertical plate, a supporting block, a hinged seat, a base, an angle indicating block and a rotating Composed of a ring body, the vertical plate is perpendicular to the upper end surface of the base, and a through hole is opened on the vertical plate. There is a radial through groove on the rotating ring body, and a through hole on the annular protrusion. The angle indicating block is slidably connected in the through groove and the through hole, and connects with the protrusion on the rectifying blade positioning block through the gap at the end. The platform is inserted to form an extended structure of the datum surface on the boss. The support block is located on the upper end surface of the base. The contour of the upper surface of the support block is consistent with the curve shape of the section to be measured on the blade. One end of the pressure rod is hinged on the hinged seat. The other end is inserted into the bolt through the notch and locked by the nut. The invention can conveniently judge whether the dimension of rectifying blade parts is qualified after processing.
