Problems solved by technology

[0002] The high and low pressure compressor drum is a key component of an aero-engine. When a certain type of engine is being repaired, it is necessary to check the runout of the high and low pressure compressor drum to prevent the engine from vibrating due to excessive deformation of the drum. In actual repairs, Runout inspection is a key process, and its quality determines whether the engine test is qualified or not. During the measurement, due to the error of the installation, the axis of the drum and the axis of the measuring device cannot completely coincide, which makes the measurement error too large and affects the Production

Embodiment 1

[0020] Embodiment 1: a kind of reference adjustment device of aero-engine compressor drum runout measurement, it comprises the following steps when it is used:

[0021] S1, the engine compressor drum is installed on the measurement platform 4;

[0022] S2. Use a dial indicator to detect the runout value of the upper and lower end faces of the drum;

[0023] S3. If the runout of the upper end surface is large (≥0.01mm), it means that the installation of the drum is inclined, then use a wrench to adjust the adjustment screw 5 at the corresponding position, so that the runout of the upper end surface is not greater than 0.01mm.

Embodiment 2

[0024] Embodiment 2: a kind of reference adjustment device of aero-engine compressor drum runout measurement, it comprises the following steps when it is used:

[0025] S1, the engine compressor drum is installed on the measurement platform 4;

[0026] S2. Use a dial indicator to detect the runout value of the upper and lower end faces of the drum;

[0027] S3. If the runout of the lower end surface is large (≥0.03mm), it means that the installation of the drum is inclined, then use a wrench to adjust the adjustment screw 5 at the corresponding position, so that the runout of the lower end surface is not greater than 0.03mm.

Embodiment 3

[0028] Embodiment 3: a kind of reference adjustment device of aero-engine compressor drum beat measurement, it comprises the following steps when it is used:

[0029] S1, the engine compressor drum is installed on the measurement platform 4;

[0030] S2. Use a dial indicator to detect the runout value of the upper and lower end faces of the drum;

[0031] S3. If the runout of the upper and lower end surfaces is large (upper end surface ≥ 0.01mm, lower end surface ≥ 0.03mm), it means that the axis of the drum is parallel to the axis of the measuring device, but they do not overlap. Then use a wrench to adjust the adjustment screw 5 at the corresponding position, so that the axis of the drum coincides with the measuring device.

Abstract

The invention discloses a reference adjusting device for aero-engine compressor drum runout measurement. The device comprises a measuring platform, an adjusting screw, a drum clamping device, an adjusting screw rod and an adjusting screw rod limiting device. The bottom end of the drum clamping device is connected with the upper end face of the measuring platform through the adjusting screw; the adjusting screw rod limiting device is installed on the upper end face of the measuring platform; and the adjusting screw rod is connected with the adjusting screw rod limiting device. The beneficial effects are that the device can flexibly and slightly adjust the degree of freedom of a drum in the X-axis direction, the Y-axis direction and the Z-axis direction; through modular design, the system iscompact in structure, and convenient to manage, use and maintain; and through the drum runout reference adjusting system composed of the adjusting screw rod and the adjusting screw, the accuracy of ameasurement result is ensured, the part repairing quality is ensured, the engine maintenance cost is reduced, and the engine maintenance period is shortened.

Description

technical field [0001] The invention relates to the technical field of aero-engine maintenance, in particular to a benchmark adjustment device for measuring the runout of an aero-engine compressor drum. Background technique [0002] The high and low pressure compressor drum is a key component of an aero-engine. When a certain type of engine is being repaired, it is necessary to check the runout of the high and low pressure compressor drum to prevent the engine from vibrating due to excessive deformation of the drum. In actual repairs, Runout inspection is a key process, and its quality determines whether the engine test is qualified or not. During the measurement, due to the error of the installation, the axis of the drum and the axis of the measuring device cannot completely coincide, which makes the measurement error too large and affects the Production. Therefore, it is necessary to develop a runout measurement and adjustment device, so that the axis of the drum coincide...
