Technical Field

The invention relates to the technical field of maintenance of aero-engines, in particular to a reference adjusting device for measuring drum barrel runout of an aero-engine air compressor.

Background

The drum barrel of the high-low pressure compressor is a key component of an aeroengine, when a certain type of engine is repaired, the jumping amount of the drum barrel of the high-low pressure compressor needs to be checked, the problem that the deformation of the drum barrel is too large to cause vibration of the engine is solved, in actual repair, the jumping amount check is a key process, the quality of the jumping amount check determines whether the engine is qualified in test run, and in measurement, due to the problem of installation errors, the axle center of the drum barrel cannot be completely coincided with the axle center of a measuring device, so that the measurement errors are too large, and production is influenced. Therefore, a jitter measurement adjusting device needs to be developed, so that the drum coincides with the axis of the measuring device during measurement, and the accuracy of a measurement result is ensured.
