The application belongs to the field of aero-engines, and in particular relates to an on-line measuring and adjusting device for the concentricity of a wearable fan ring. It consists of four parts: fixing, measuring, grinding and dust removal. The fixing and installation of the overall tooling can be realized through the fixing component, which can ensure the consistency of tooling installation measurement and adjustment; through the double dial indicator in the measuring component, the measurement of the circumferential runout value of the easy-wear ring relative to the fan rotor under the engine assembly state can be realized. The accuracy of the measurement is ensured; the grinding of the easy-grinding ring of the fan is realized through the grinding component, which meets the consistency of the grinding inclination angle of the milling cutter and the design inclination angle of the easy-grinding ring; Avoid contamination of engine runner surfaces. This application can actually measure the size and circular runout of the wearable ring in real state, with high measurement accuracy, and can adjust the grinding according to the measurement results, improve the concentricity of the wearable ring, improve the assembly quality, reduce the risk of blade tip collision, and improve the engine work reliability.
Description
Technical field [0001] The present application belongs to the field of aviation engines, and more particularly to a fan-like multi-worry-free online measurement and adjustment device. Background technique [0002] A large conversation ratio of the engine fan is easy to worn after the engine work, and there is a different degree of local partition, indicating that the concentricity between the fan rotor blades and the fan-like molar is poor, resulting in a calorie Partial touch. If this is not resolved, the rotor leaf tip is continuously worn, and the gap of the fan leaf tip is constantly amplified, the engine fan performance and reliability are lowered. [0003] In the prior art, the industry has a concentricity of the fan-rich mill and the rotor blade tip, which mainly rely on the engine assembly, and the clearance between the fan leaf tip and the easing ring is mainly used, and the actual situation of the circumferential gap is recorded. Value, indirectly reflect the concentric...
