The invention discloses a dovetail groove detection device and detection method for a ring-shaped piece and belongs to the detection measuring tool field. The dovetail groove detection device includesa rectangular detection block, a groove type detection block, a connection block and a positioning block; the rectangular detection block is cuboid-shaped; the cross-sectional shape of a side edge ofthe groove type detection block is identical with the cross-sectional shape of a dovetail groove, wherein the side edge of the groove type detection block is perpendicular to the groove type detection block; the basic size of a vertical distance between the ball center of a positioning ball and a first side is equal to the basic size of a vertical distance between the axis of a workpiece and thegroove bottom of the dovetail groove; and the basic size of a vertical distance between two end surfaces of the groove type detection block is equal to the basic size of a vertical distance between two ends of the dovetail groove. When the ring-shaped piece is detected, the ring-shaped piece can be arranged on the detection platform of a three-dimensional coordinate detector; the groove type detection block is inserted into the dovetail groove, and the positioning ball is made to be located above the rectangular detection block; a coordinate system and a reference plane are established; and whether the dovetail groove is qualified is judged according to the relative positions of the center of the positioning ball and the reference plane.
Description
technical field [0001] The invention relates to the field of measuring tools, in particular to a dovetail groove detection device and a detection method for ring parts. Background technique [0002] The casing of the gas turbine is ring-shaped, and there are multiple dovetail grooves in the casing of the gas turbine. The dovetail grooves are used for the installation of the blades. In order to ensure the reliability of the blade installation and ensure the normal operation of the gas turbine, the dimensional accuracy and position of the dovetail grooves are different. high demands. [0003] Since the dovetail groove for installing the blades in the gas turbine casing is a slanted groove, that is, the extension direction of the dovetail groove is not parallel to the axis of the annular casing, and the casing of the gas turbine is thin, so it is difficult to find the measurement reference, so it is difficult to detect the dovetail groove . Contents of the invention [0004...
