Abstract

The invention discloses a turbine generator rotor assembly roundness measuring device. A central rotating body is axially supported on the upper end face of a column, and radially rotates around the column. By adjusting the eccentric amount of an eccentric shaft, the central rotating body can be adjusted to be parallel to and coaxial with the axis of the column. By adjusting a top wire I, the horizontal rotating accuracy of a measuring arm around the column can be adjusted. By adjusting a top wire II, the rotating center of the measuring arm can be adjusted to be concentric with a rotor. A gauge stand can slide along a measuring rod, so that the device can accurately measure the roundness and the concentricity of measurement points of different heights and positions in a rotor assembly process. The turbine generator rotor assembly roundness measuring device provided by the invention has the advantages of simple structure, easy installation and debugging, high measuring accuracy, safe and reliable use and low cost. A universal, serialized and standardized product can be realized.

Description

Technical field: [0001] The invention relates to a circle measuring device for assembling a hydraulic generator rotor. Background technique: [0002] The hydro-generator rotor is one of the core components of the hydro-generator set. Usually, during the assembly process, it is necessary to measure the dimensional accuracy, roundness and coaxiality from the outer circle of the yoke assembly to the center line, and the outer circle to the center of the magnetic pole assembly. Dimensional accuracy, roundness and coaxiality of wires. At present, the structure of the circle measuring device usually used in the assembly of the rotor of the hydroelectric generator in the domestic hydropower site is to design the base as a disc handle flange structure with a convex seam, and the outer diameter of the convex circle and the rotor bracket positioning hole stop The mouth adopts clearance fit, and there are more than three measuring process holes evenly distributed on the diameter surf...
