A method for quickly realizing the detection of blade profile by inductance meter

Abstract

A method for quickly realizing the detection of the profile surface of the blade by the inductance meter is as follows: first, the position adjustment of the measuring tool and the measuring contact; Establish benchmarks on the front end face and side plane, and measure the three leaf pots or leaf back samples respectively according to the specified point positions. The difference between the measured value and the data value given in the design drawing is the combined error value of the leaf pot or leaf back side ;Third, the inductance meter detects the initial zero position adjustment; uses the software function to start the leaf basin or leaf back zero setting; fourth, eliminates the zero correction of the combined error value of the combined standard part; fifth, the blade measurement. The invention has the advantages of simplifying the traditional complex three-dimensional curved airfoil integral standard part into a split structure that is more convenient for processing and manufacturing, greatly reducing the difficulty of standard part manufacturing, shortening the manufacturing cycle, low cost, high precision, and high detection efficiency. greatly improved.

Description

technical field [0001] The invention relates to the field of processing and detection technology, in particular to a method for quickly realizing the detection of blade profiles by an inductance meter. Background technique [0002] At present, the machining accuracy requirements of the blade profiles of aero-engines and gas turbine compressors are getting higher and higher, and the development cycle of new machine blades is getting shorter and shorter. , with faster efficiency and convenience, and at the same time, the process preparation must have a faster response capability. The detection and monitoring of the blade surface has always been a key and important link in the blade manufacturing process. Among them, the detection method of the inductance meter has always been the most important part of the blade surface processing because of its high detection accuracy, fast detection speed, and convenient operation. It is an effective method that is expected to be widely use...
