Abstract

Disclosed are a cylindrical probe and a method for measuring and scanning the blade profile of a blisk. The cylindrical probe is composed of an extension bar I (1), a five-dimension adapter I (2), a universal joint (3), an extension rod II (4), a five-dimension adapter II (5) and a cylindrical probe I (6). One end of the extension rod II (4) is connected with the extension bar I (1) through the five-dimension adapter I (2) and the universal joint (3). The problems of data discontinuity and large measurement error are solved, data splicing error is avoided, and the efficiency of measurement is improved. With the cylindrical probe and the method for measuring and scanning the blade profile of a blisk, continuous scanning measurement of the blade profile of a blisk can be completed at one attempt. Data is continuous and complete, there is no data missed, and there is no cohesion error. The measurement precision and speed are high, and the stability is good. High-efficiency and high-precision measurement of blisks is realized. The cylindrical probe and the method satisfy the aero-engine blisk quality control requirements, and adapt to the progress demand of batch production on the production site for measurement.

Description

technical field [0001] The invention relates to the technical field of structural design and application of a cylindrical probe, and in particular provides a cylindrical probe and a method for measuring and scanning the airfoil profile of an integral blade disk. Background technique [0002] The overall blisk structure is complex, and the blades distributed on the circumference are stacked on each other. The measurement system of the overall blisk is generally composed of a three-coordinate measuring machine with scanning function and its supporting single-axis precision turntable. In the prior art, the measurement of the overall blisk The main method and existing problems of leaf shape: [0003] (1) Segmented scanning of leaf shape discontinuities leads to data omission [0004] In the existing technology of measuring the overall blisk blade shape, the spherical probe commonly used by the three-coordinate measuring machine is used. In order to solve the problem of interfer...
