Abstract

The invention provides a measuring tool for a dovetail groove of a gas turbine disk and a measuring method using the same. The invention relates to a measuring tool and a measuring method using the tool. The measuring tool and the measuring method solve problems that the horizontal plane range from the bottom surface of a dovetail groove of an existing gas turbine disk to the central line of the disk belongs to space structure and cannot be measured directly. The measuring tool for a dovetail groove of a gas turbine disk comprises a measuring body, a pull rod, a pulley, a nut, a baffle plate, and screws. The measuring method using the measuring tool for a dovetail groove of a gas turbine disk comprises the following: installing a dovetail groove shaped measuring bottom into the dovetail groove of the disk, the baffle plate tightly abutting against the side surface of the disk, and screwing the nut, so that the measuring body compresses the bottom surface of the disk dovetail groove along the pulley, until the edge center point of the bottom end of the dovetail groove shaped measuring bottom is overlapped with the bottom end edge center point of the disk dovetail groove, and measuring and calculating to obtain the horizontal plane range from the bottom end edge center point of the disk dovetail groove to the central line of the disk. The invention relates to a measuring tool for a dovetail groove of a gas turbine disk and a measuring method using the same.

Description

Technical field [0001] The invention relates to a measuring tool and a measuring method using the tool. Background technique [0002] The gas turbine wheel disc is the core component of the gas turbine. Its structure is complex and it is difficult to process and measure. In particular, the distance from the bottom of the dovetail groove to the horizontal plane of the wheel disc center line is a spatial structure and cannot be directly measured. Summary of the invention [0003] The invention aims to solve the problem that the distance between the bottom surface of the dovetail groove of the existing gas turbine wheel disc and the horizontal plane of the wheel disc center line belongs to the space structure and cannot be directly measured, and provides a gas turbine wheel disc dovetail groove measuring tool and a measuring method using the tool. [0004] Dovetail groove measuring tool for gas turbine wheel disc, which includes measuring body, tie rod, pulley, nut, baffle and screw; m...
