The invention relates to the technical field of aero-engine blade ring type part measurement, in particular to a blade space angle measuring device for a blade ring structure part, which comprises anangle measuring tool and a limiting measuring tool. The limiting measuring tool is used for fixing a blade ring type part to be measured and the angle measuring tool, and the angle measuring tool is used for measuring the blade space angle. According to the invention, the problem that the blade space angle in an impeller and a blade ring type structural part is difficult to measure is solved, theblade space angle can be directly and quickly measured and directly read, so that the problem of long blade space angle measurement period of the part is solved, the occupation of three-coordinate equipment can be reduced, the development and production period of the part is shortened, and the device has a wide application prospect.
Description
technical field [0001] The invention relates to the technical field of measuring an aeroengine leaf ring type part, in particular to a blade space angle measuring device for a leaf ring structural part. Background technique [0002] More and more impeller-type and leaf-ring structural parts are used in modern jet aeroengines. The blades of these parts control the direction of air intake, so the requirements for the angle of the blades are relatively strict. The only feasible method of measurement is CMM. The three-coordinate measurement needs to scan the leaf shape points, and the detection cycle is long. After the three-coordinate scanning, manual fitting is required to obtain the angle result, and the leaf ring structure parts have a large number of blades, and the workload is very large, which is difficult to adapt to the mass production of parts. , so it is very inefficient to use three coordinates to detect this size. Contents of the invention [0003] In order to s...
