Embodiment 1

[0031] The steps of the method for measuring the shape and size of the blisk blade described in this embodiment are:

[0032] (1) The position measurement tool takes the circular arc peripheral surface of the blisk as the measurement reference plane, and the positioning plate I (11) is fixed on the blisk through its bottom surface and the positioning pin I (13) and positioning pin II (14). On the circular arc peripheral surface, the positioning pin III (15) pins a point on the profile surface of the blade root; use the position measuring tool to adjust the dial gauge to zero on the standard part of the table; use the measuring pin I (16) of the dial gauge before processing Fix it on the measuring rod I (12), select any point on the top surface of the blade as the measuring point, and use the dial gauge to measure the change of the gauge value of the measuring point as +0.1mm. The distance change in the direction is +0.1mm. After processing, measure again according to the steps...

Abstract

A form, position and dimension measuring method of a blisk blade and a tool thereof are disclosed. The measuring method comprises the following steps: (1) taking an arc circumferential surface of blisk as a measuring reference surface, selecting any point on a blade top type surface as a measuring point, measuring a distance variation of the point relative to a normal direction of the measuring reference surface so as to obtain a position variation of a blade; (2) taking an arc end surface of the blisk as the measuring reference surface, selecting any point on the blade as the measuring point, measuring the distance variation of the point relative to an axial direction of the measuring reference surface so as to obtain a blade length variation. The invention provides the form, position and dimension measuring method of the blisk blade and the tool thereof. Intake and exhaust edge dimension change of the blade and a blade deformation situation can be real-timely monitored. Under the current condition, the real-time monitoring is performed inconveniently; a detection period is long; efficiency is low and cost is high. By using the method and the tool of the invention, the above problems can be solved.

Description

[0001] technical field [0002] The invention relates to the measurement of the whole blisk blade after processing, and in particular provides a method and tool for measuring the shape, position and dimension of the whole blisk blade. Background technique [0003] In the fourth-generation engine, the blisk is an important part of the core. The blade surface structure of the blisk is a complex spatial surface. The processing size and position accuracy are tested by using a three-coordinate measuring machine after processing. For detection, this detection method has long cycle, low efficiency, high cost, and poor real-time monitoring ability. The present invention particularly provides a method and tool for measuring the shape, position and size of blisk blades, which are used for real-time detection of blisk blades , which solves the problems of long period, low efficiency, high cost and poor real-time monitoring ability of the original detection method.
