Abstract

The invention discloses a compressor rotor balancing clamp which balances a low-pressure compressor rotor. The low-pressure compressor rotor comprises a low-pressure shaft, a case wrapping the low-pressure shaft, a bearing sleeving one end portion of the low-pressure shaft and a low-pressure internal support arranged in the case and fixedly connected with the low-pressure shaft. The compressor rotor balancing clamp comprises a first swing frame which is arranged on the other end portion of the low-pressure shaft to fixedly support the low-pressure compressor rotor, a second swing frame which is arranged on the bearing to radially position and support the low-pressure compressor rotor, a positioning rack which is arranged on the low-pressure internal support to radially position the low-pressure compressor rotor, and an axial positioning mechanism which is connected with the first swing frame, the second swing frame and the positioning rack to axial position the low-pressure compressor rotor. The technical problem of bouncing during low-speed dynamic balancing test of the low-pressure compressor rotor is solved, the positioning is reliable, the accuracy is high, the structure is simple, the weight is light and the operation is convenient. Test data obtained are stable, and test requirements of an engine are met.

Description

technical field [0001] The invention relates to the field of dynamic balancing fixtures, in particular to a compressor rotor balancing fixture. Background technique [0002] The low-pressure compressor rotor is an important component of the aero-engine. With the development of science and technology, the performance of the aero-engine continues to improve. The low-pressure compressor rotor is mainly composed of a thin-walled casing, a low-pressure shaft, a bearing and a low-pressure inner support. Since the structure of the low-pressure compressor rotor is a mixture of flexibility and rigidity, it was found during the low-speed dynamic balance test that the concentricity of the low-pressure compressor rotor was difficult to ensure, which caused the test to jump, thereby affecting the authenticity and stability of the test data. [0003] Therefore, the jumping phenomenon of the low-pressure compressor rotor during the low-speed dynamic balance test is a technical problem tha...
