Its working conditions are very harsh, and it needs to withstand high temperatures, high pressures, high speeds and high stresses, so the requirements for materials and manufacturing processes are very high. When testing after processing, it is usually necessary to use a tool for testing. The measurement of the turbine disk blade to the shaft end face involves many aspects, including the measurement of geometric shapes and dimensions, the detection of crack defects, etc. When using a tool for testing, the detection tool ensures the accuracy and reliability of the measurement through components such as clamping, positioning and fixing.

[0003] A turbine disk measuring device is disclosed in the patent with application number 202310576323.4. The turbine disk measuring device does not interfere with the turbine disk during the measurement process. The rotating truss can realize the rapid and accurate detection of whether multiple related holes, laces or grooves of the turbine disk meet the position requirements; in response to the above application, and in combination with the existing detection method, it is known that when measuring the distance from the specified point of the irregular blade of the turbine disk to the shaft end face, since the existing detection fixed point and the measuring surface are not on the same plane, the points on both sides of the vernier card size cannot be located, and the results need to be obtained through multiple calculations and measurements. The measurement is cumbersome and affects the measurement accuracy and work efficiency. For this reason, we propose an auxiliary measurement tool from the turbine disk blade to the shaft end face.

[0020] Example 1

[0021] See also Figure 1 and Figure 2 The utility model provides a technical solution: the main function of the turbine disk is to convert the energy of high-temperature and high-pressure combustion gas into mechanical energy to drive the rotation of other components such as the compressor and the fan. It is one of the key components of the power output in the engine, and its reliability directly affects the performance and life of the engine. After the turbine disk is processed, in order to ensure its accuracy, it is usually necessary to perform various measurements on the turbine disk. The auxiliary measurement tool from the turbine disk blade to the shaft end face includes a tool body 100, and both ends of the tool body 100 are provided with an integrated thickness measuring seat plate 101. The front surface of the tool body 100 is located between the two thickness measuring seat plates 101 and is provided with a shaft alignment groove 102. When installing the turbine disk, the shaft alignment groove 102 can fit with the turbine disk shaft. The inner side limit of the tool body 100 is installed with a bearing assembly seat 200, and one end edge of the bearing assembly seat 200 is provided with a An integrated turbine fixing seat 203 is provided with a fixing bolt 204 which is screwed on the turbine fixing seat 203, and an integrated bearing fixing seat 201 is symmetrically provided on both sides of the tooling body 100, and a fixing bolt 202 is installed on the bearing fixing seat 201. When the measuring tool in the application is used to measure the distance from the turbine blade to the shaft end face, the turbine can be taken out, the turbine shaft is aligned with the bearing assembly seat 200, and the side of the turbine is tightly fitted in the shaft alignment groove 102, and then the fixing bolt 204 on the turbine fixing seat 203 is adjusted to fix the shaft of the turbine disk. After the installation is stable, the vernier caliper is taken out, one end of the vernier caliper is attached to the back of the thickness measuring seat plate 101, and the other end is attached to the measuring point of the turbine blade to obtain data, and the data from the turbine disk blade to the shaft end face can be obtained by subtracting the fixed thickness of the thickness measuring seat plate 101 from the obtained data.

[0022] Specifically, the bearing assembly seat 200 is rotatably installed on the tooling body 100. The rotation method can adjust the installed turbine disk, which is used to detect the distance from different points on the turbine disk to the end face, and the bearing assembly seat 200 and the tooling body 100 are fixed by fixing bolt 1 202. Fixing bolt 204 is used to fix the measured workpiece to ensure stability during measurement. During the detection process, if it is necessary to detect other points on the entire circumferential surface, the bearing assembly seat 200 can be directly rotated. After rotation adjustment, tighten the fixing bolt 1 202 on the bearing fixing seat 201 when measuring again. Measurement is performed by rotation and fixation, without multiple disassembly and assembly, which improves the practicality of measurement while achieving better detection.
