High-pressure rotor inner hole concentricity measuring instrument

Abstract

The invention provides a high-pressure rotor inner hole concentricity measuring instrument and belongs to the field of detecting equipment. The instrument comprises an air floating turntable, a connecting sleeve, a measuring rod and a sensor; the air floating turntable comprises a rotating body and a fixing shaft sleeve; the measuring rod is detachably and vertically fixed at the lower end of therotating body; the sensor is embedded in the measuring rod and is corresponding to the inner cross section of a high-pressure rotor; a connecting sleeve is fixedly connected with the lower end of thefixing shaft sleeve; and the connecting sleeve is arranged at the outer periphery of the rotating body and fix the upper end of the high-pressure rotor. With the high-pressure rotor inner hole concentricity measuring instrument of the invention adopted, the concentricity of the high-pressure rotor can be quickly and accurately measured, and operation is convenient and quick.

Description

technical field [0001] The invention belongs to the field of testing equipment and relates to measuring equipment for high-pressure rotors of aero-engines, in particular to a concentric measuring instrument for inner holes of high-pressure rotors with an air-floating structure. Background technique [0002] Aeroengine is a highly complex and precise thermodynamic machine, which provides the aircraft with the power required for flight. It directly affects the performance, reliability and economy of the aircraft. The high-pressure rotor is an important part of the aeroengine. Under its working condition, For ultra-high-speed operation, the concentricity of the high-pressure rotor must be guaranteed. Therefore, it is very important to measure the concentricity of the high-pressure rotor of an aero-engine. At present, there is no convenient and efficient measurement method. [0003] If the traditional structure is used, the precision of the structure itself cannot be guaranteed,...

[0002] Aeroengine is a highly complex and precise thermodynamic machine, which provides the aircraft with the power required for flight. It directly affects the performance, reliability and economy of the aircraft. The high-pressure rotor is an important part of the aeroengine. Under its working condition, For ultra-high-speed operation, the concentricity of the high-pressure rotor must be guaranteed. Therefore, it is very important to measure the concentricity of the high-pressure rotor of an aero-engine. At present, there is no convenient and efficient measurement method

[0003] If the traditional structure is used, the precision of the structure itself cannot be guaranteed, and the matching accuracy of the detection structure is far lower than that of the tested part, then the measurement structure is meaningless, and it is even more impossible to judge whether the part is good or bad. Detection, not only expensive equipment, but also troublesome operation and low work efficiency
