Abstract

An angular displacement measuring tool for a linkage mechanism of a stator assembly of a gas compressor and a use method are disclosed. The angular displacement measuring tool comprises a mounting plate, a decoder is fixedly mounted on the mounting plate through a connecting screw, an optical axis of the decoder passes through the mounting plate and is connected with one end of a transmission shaft through a coupling, the other end of the transmission shaft is provided with a groove, a boss of a transmission nut is inserted into the groove of the transmission shaft and is fixed through a fastening screw, and one end of a supporting leg penetrates through a through hole in the edge of the mounting plate and is fixed through a fastening nut; the transmission nut is in threaded connection with a compressor casing crankshaft, the rotation angle of the transmission nut is synchronous with that of the compressor casing crankshaft, the bottom end of the supporting leg is in threaded connection with the compressor casing crankshaft through a bolt, and it is guaranteed that angle output is stable and effective. The tool eliminates manual measurement errors, improves the measurement precision, improves the calibration automation degree, provides technical reserve for the development of an automatic measurement technology, has practical application values, and is suitable for batch production and use.

Description

technical field [0001] The invention belongs to the technical field of special tools for aero-engines, and in particular relates to a tool for measuring angular displacement of a linkage mechanism of a compressor stator assembly and a method for using it. Background technique [0002] When carrying out joint adjustment and inspection of the adjustment rules, the core machine of the engine is installed, and the angle values ​​of the three states are measured by pulling the main arm; when the adjustment mechanism of the compressor stator blade is calibrated, the control valve of the actuator is opened with the current source excitation, Manual pressing is used to control the action of the actuator to rotate the guide vane. When the angle to be calibrated is reached, the data acquisition system collects the output signal of the position sensor for calibration. Both of these two processes adopt the method of manually reading the dial, and the accuracy is low; and measurement and...
