The geometric size of the blade determines the working performance of the engine, so it is necessary to accurately measure the size and shape of the turbine blade. However, the existing turbine blade is measured by the staff with a ruler, and such measurement method is not only inconvenient to operate but also inaccurate.

[0003] Therefore, it is necessary to provide a turbine blade measuring device to solve the problems in the background art. SUMMARY

[0004] The utility model aims at providing a turbine blade measuring device to solve the technical problem that the existing turbine blade is measured by the staff with a ruler, which is not only inconvenient to operate but also inaccurate.

[0005] In order to solve the above technical problem, the utility model provides a turbine blade measuring device, which comprises a bottom plate, a rotating shaft provided on the bottom plate, a cavity provided in the rotating shaft, two springs provided in the cavity, two extrusion blocks provided at one end of the two springs, and a scale provided on the bottom plate.

[0006] As a further description, the rotating shaft is movably connected with the bottom plate, the bottom plate is in a cylindrical shape, and the rotating shaft is arranged at the center of the bottom plate.

[0007] As a further description, the two extrusion blocks are identical in shape and symmetrical in position.

[0008] As a further description, the scale is arranged on the upper surface of the bottom plate, and the size of the scale is equal to the radius of the bottom plate.

[0009] Compared with the prior art, the utility model has the advantages of:

[0010] 1. The combination of the rotating shaft, the cavity, the spring and the extrusion block can realize accurate measurement of the size and shape of the turbine blade. Compared with the traditional manual ruler measurement, this non-contact or micro-contact method can reduce human error and improve the accuracy and reliability of the measurement.

[0011] 2. Since the extrusion blocks are identical in shape and symmetrical in position, they can adapt to the measurement requirements of turbine blades of different shapes and sizes. At the same time, the scale is directly arranged on the upper surface of the bottom plate, and the size is matched with the radius of the bottom plate, so the measurement results can be directly read without complex calculation or conversion.

[0012] 3. Traditional manual measurement methods are easily affected by various factors such as the skill level of the measurer, the accuracy of the measuring tools, and environmental factors, resulting in large measurement errors. However, the measuring device of this invention reduces these sources of error through mechanical structure design, improving the stability and consistency of the measurement.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Reference Figs. 1-3A turbine blade measuring device includes: a base plate 1, a rotating shaft 2 mounted on the base plate 1, a cavity 3 inside the rotating shaft 2, two springs 4 inside the cavity 3, and a pressing block 5 at one end of each spring 4. A scale 6 is mounted on the base plate 1. In use, the two pressing blocks 5 are pressed together, and the center of the turbine is inserted. The springs 4 at both ends of the pressing blocks 5 clamp the center of the turbine, thus fixing the turbine to the device. After installation, the part to be measured is rotated above the scale 6 for observation and measurement. This non-contact or micro-contact method, compared to traditional manual ruler measurement, reduces human error and improves the accuracy and reliability of the measurement.

[0023] The rotating shaft 2 is movably connected to the base plate 1, which is cylindrical. The rotating shaft 2 is located at the center of the base plate 1. Its central location on the base plate 1 makes the measuring device more stable during measurement, reducing measurement errors caused by shaking or offset. The rotating shaft 2 can rotate on the base plate 1, allowing for finer adjustments and positioning, thus improving measurement accuracy and facilitating operation by staff.

[0024] The two extrusion blocks 5 are identical in shape and symmetrically positioned. This ensures balance and stability during the measurement process, avoids measurement deviations caused by asymmetry, improves the reliability of the measurement results, and easily adapts to turbine blades of different shapes and sizes, enhancing its versatility.

[0025] The scale 6 is located on the upper surface of the base plate 1, and its size is equal to the radius of the base plate 1. This ensures the accuracy of the measurement results, reduces errors caused by mismatched scale dimensions, and the more intuitive scale design improves measurement efficiency, enabling staff to obtain measurement results quickly and accurately.
