Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] To further understand the contents of this utility model, a detailed description of this utility model will be provided with reference to the accompanying drawings.

[0030] Reference Figures 1-3 This utility model discloses a blade measuring fixture, comprising an inspection body 1 as the core platform of the entire fixture. A first finished component 2 is mounted on the top front end of the first finished component 1, and a second finished component 18 is mounted on the top rear end. The first finished component 2 and the second finished component 18 are fixed to the inspection body 1 by evenly distributed first pins 3. The design of the first pins 3 enables precise positioning of the first finished component 2 and the second finished component 18, and significantly improves the overall stability of the fixture. The first pins 3 are installed on the outer walls of the first finished component 2 and the second finished component 18 using an interference fit. The pin hole positions are precisely calculated to ensure that the tolerance range during assembly is controlled within 0.01 mm, thereby reducing measurement deviations caused by assembly errors. A detection component is also provided at the rear end of the first finished component 2. This detection component is used for step-by-step detection of different parts of the blade. The detection component includes multiple template units, which are arranged sequentially and tightly integrated at the rear end of the first finished component 2 to form a complete detection system.

[0031] The specific structure of the inspection component is as follows: Template No. 6 (lower part 16) is located at the rear bottom of the first finished part 2, with Template No. 6 (upper part 10) correspondingly positioned on its top. The gap between Template No. 6 (upper part 10) and Template No. 6 (lower part 16) is pre-set according to the specific parameters of the blade to meet the measurement requirements of a specific part of the blade. Template No. 5 (lower part 15) is located at the rear end of Template No. 6 (lower part 16), with Template No. 5 (upper part 6) correspondingly positioned on its top. Template No. 4 (lower part 14) is located at the rear end of Template No. 5 (lower part 15), with Template No. 4 (upper part 8) correspondingly positioned on its top. Template No. 3 (lower part 13) is located at the rear end of Template No. 4 (lower part 14), with Template No. 3 (upper part 7) correspondingly positioned on its top. Template No. 2 (lower part 12) is located at the rear end of Template No. 3 (lower part 13), with Template No. 2 (upper part 9) correspondingly positioned on its top. Template No. 1 (lower part 11) is located at the rear end of Template No. 2 (lower part 12), with Template No. 1 (upper part 5) correspondingly positioned on its top. Each template unit consists of a lower template and an upper template, forming a corresponding inspection structure. The number and arrangement of template units can be flexibly adjusted according to actual testing needs to adapt to the measurement requirements of blades of different sizes. For example, when testing larger blades, the number of template units can be increased; while when testing smaller blades, the number of template units can be reduced, thus achieving personalized customization.

[0032] To further improve the overall stability and anti-interference capability of the tooling, evenly distributed second pins 4 are provided at the rear bottom of templates 1-11, 2-12, 3-13, 4-14, 5-15, and 6-16. The second pins 4 are fixed to the rear bottom of the template unit via threaded connections, and their pin hole positions are also precisely designed to ensure the stability and measurement accuracy of the template unit during the testing process. The second pins 4, together with the first pins 3, form a double-fixing design, effectively reducing measurement errors caused by external vibration or improper operation. Furthermore, the design of the second pins 4 also considers the fit clearance within the machining tolerance range, and the pin hole positioning further enhances the reliability of the tooling during long-term use.

[0033] The main body 17 is located at the rear end of the first finished part 2, and is used to connect the detection component and tightly integrate the detection component with the first finished part 2. The main body 17 is fixed to the first finished part 2 by threaded connection or interference fit, and its internal design includes a guide groove structure to guide the installation and disassembly of the detection component. The guide groove structure allows the detection component to slide smoothly to the designated position during installation, thereby improving assembly efficiency. In addition, the guide groove structure also has a certain limiting function to prevent the detection component from shifting or loosening during use, thereby further improving the reliability of the tooling. The main body 17 is made of high-strength alloy steel, and after precision machining, its surface hardness reaches HRC50 or higher, ensuring good wear resistance and deformation resistance during long-term use.

[0034] Working principle: The blade to be tested is placed between the first finished part 2 and the second finished part 18. It is initially positioned by the first pin 3. The position of the testing component is adjusted so that the gap between the lower 16 of the sixth template and the upper 10 of the sixth template is aligned with a specific part of the blade. Different parts of the blade are tested step by step. The gap size between the upper and lower units of each pair of templates has been preset according to the specific parameters of the blade to ensure the accuracy of the measurement results. The test data is recorded, and the blade is judged to meet the design requirements based on the measurement results. After the test is completed, the testing component is quickly disassembled through the guide groove structure for easy subsequent maintenance or replacement.
