Adjustable flow blade rotation angle detection device and detection method

Abstract

The invention discloses an adjustable flow blade rotation angle detection device and detection method. A digital display angle detector is fixedly connected with a detected adjustable flow blade, so that the rotation angle of the adjustable flow blade can be detected by rotating the adjustable flow blade; a self-locking nut buckle thread is exposed on the long shaft of the adjustable flow blade, asupport is connected through the thread, the digital display angle detector is fixed on the support, and the rotation angle of the adjustable flow blade can be measured only by one-time disassembly and assembly during detection. The adjustable flow blade rotation angle detection device can be installed on N adjustable flow blades at the same time for one-time detection, and the detection efficiency can be greatly improved. After the adjustable flow blade rotation angle detection device and method are adopted, the risk of scrapping caused by repeated disassembly and assembly of the self-locking nut is effectively avoided, more importantly, the detection device is convenient to disassemble and easy to operate, the detection time is greatly shortened, the detection efficiency is effectivelyimproved, and meanwhile, the labor intensity of operators is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of engine assembly, and specifically relates to a detection device and a detection method for an adjustable flow vane rotation angle. Background technique [0002] The compressor is the core component of the turbine engine. It is mainly composed of three parts: casing, rotor blades and rectifier blades. The assembly quality directly affects the performance and stability of the engine. The rectifying blades are divided into fixed rectifying blades and adjustable rectifying blades. The fixed rectifying guide vanes can be directly fixed in the special-shaped ring groove on the inner wall of the casing with various types of tenons (edge ​​plates). The neck fits in the case of the engine. The connection between the rectifier blade and the casing must ensure reliable force transmission, good positioning, sealing and thermal compensation, so as to provide stable compressed air with a certain direction and flow rat...

AI Technical Summary

Problems solved by technology

[0007] Using the above-mentioned angle detection device and method, it is necessary to disassemble and assemble the thread for 1 piece of adjustable flow vane as many as 13 times. For a certain type of engine, the adjustable flow vane is divided into 3 stages with about 200 blades, and the number of disassembly and assembly of the thread needs to be 13*200=2600 Once, it takes about 3 working days to detect a set of adjustable flow blades, which is labor-intensive and low-efficiency
