Measuring tool and method for measuring thickness of adjusting gasket of guide vane equipment

The invention relates to a measuring tool and method for measuring the thickness of an adjusting gasket of guide vane equipment. The measuring tool comprises a shaft component and two rotary measuringcomponents which are symmetrically arranged at the two ends of the shaft component. The rotation measuring part comprises a rotating part capable of rotating around a shaft part, and a dial indicatorinstalled on the rotating part. The two rotating pieces are kept fixed at the axial positions of the shaft component, the opposite inner side end faces of the two rotating pieces are straight faces and are parallel to each other, a measuring rod of the dial indicator is perpendicular to the inner side end faces of the rotating pieces, and the measuring head is located on the inner sides of the rotating pieces. The measuring method is carried out by adopting the measuring tool and is used for determining the thickness of the adjusting gasket between the connecting flange and the web plate of the base.
