Embodiment

[0048] The test method of the disk parts with axial deflection applied in the present embodiment, its process is as follows:

[0049] Step 1, fixedly assembling the disc part 9 with the central shaft 3-1, and connecting the transfer boss 9-1 on the outer edge of the disc part 9 with the disc edge 8-1 of the swash plate 8 through the transfer part 10; Connect the adapter 2 with the output shaft of the rotating parts tester;

[0050] Step 2, drive the adapter 2 to rotate through the rotary parts tester, the rotation of the adapter 2 drives the central axis 3-1 of the swash plate main body 3 and the swash plate 8 to rotate synchronously; the rotation of the central axis 3-1 drives the disks The part 9 rotates synchronously with the central shaft 3-1;

[0051] After the adapter 2, the central shaft 3-1, the swash plate 8 and the disk parts 9 rotated, at the side opposite to the adapter part 10 at the edge 8-1 ( figure 1 and figure 2 The first dynamic balance adjustment zone 1 ...

Abstract

The invention discloses a test device and method. The device includes a swash plate main body, an adapter, an adapter and an adapter part. The swash plate main body is a rotary structure; The output shaft of the rotating parts tester is connected; the main body of the swash plate includes the central shaft and the swash plate. The swash plate is set at one end of the central shaft. The edge of the plate, the side of the plate edge facing the central axis is connected with the transfer part; the central axis is used to assemble with the central hole of the plate-like parts, when the central hole of the plate-like parts is fixedly assembled with the central axis, the outer edge The transfer boss is connected with the transfer part. The test device of the invention can be used safely under the condition of rotation, and at the same time can apply axial deflection to disc parts, improve test accuracy and reduce test required expenses.

Description

technical field [0001] The invention belongs to the technical field of test of aero-engine disk parts, and in particular relates to a test device and method. Background technique [0002] The disk parts of the aero-engine are its key components, and the test of the disk parts is an important basis for verifying the life of the engine disk parts and ensuring the safety of the engine. Existing test fits have a large number of tooling, resulting in a complex structure of the test device and poor stability under the rotating test condition, which may easily lead to unreliable test results, test failure or a substantial increase in test cost. Contents of the invention [0003] In order to solve the problems existing in the prior art, the purpose of the present invention is to provide a test device and method, the test device of the present invention can be used safely under the condition of rotation and can apply axial deflection to disc parts at the same time, improve test acc...
