[0042] The present invention can realize the tooling for rapid processing and testing of guide vane products. Figure 1 and Figure 2 As shown, it includes a base 101 and a first limit block 102 and a second limit block 103 arranged on both sides of the base 101. A first support 401 and a second support 402 are arranged at the bottom of the guide vane product as a supporting structure adapted to the tooling.

[0043] The upper surface of the base 101 is provided with a first through groove 304 and a first profile as a positioning structure. The height of one end of the base 101 close to the first limit block 102 is greater than that of the other end. The first profile is tilted at one end of the base 101, and the tilt angle is adapted to the angle of the bottom of the guide vane product. The first profile is used to adapt to the profile A1 at the bottom of the second support 402 of the guide vane product. The first through groove 304 is located at the other end of the base 101 and is used to set the first support 401 of the guide vane product. A locking device is correspondingly provided in the first through groove 304 for fixing the guide vane product. In this embodiment, a threaded hole is provided on the side wall of the first through groove 304, and a locking bolt 302 is provided in the threaded hole. By tightening the locking bolt 302, the first support 401 is pressed to fix the guide vane product.

[0044] The first limit block 102 and the second limit block 103 are respectively connected to the base 101 by installing screws 301. It is defined that the side of the first limit block 102 that is higher than the base 101 and close to the base 101 is the second profile, and the side of the second limit block 103 that is higher than the base 101 and close to the base 101 is the third profile. The second profile and the third profile respectively correspond to the profile A3 and the profile A4 at the two ends of the bottom of the guide vane product.

[0045] A first standard gauge block 202 is arranged between the first profile and profile A1, a second standard gauge block 203 is arranged between the second profile and profile A3, a third standard gauge block 204 is arranged below the second standard gauge block 203, and a fourth standard gauge block 205 is arranged between the third profile and profile A4. The standard gauge blocks can be made into different specifications according to usage. For example, the theoretical thickness of the first standard gauge block 202 can be made into different specifications such as 2.8mm, 2.9mm, 3.0mm, 3.1mm, etc. The thickness of the remaining standard gauge blocks can also be set as needed to measure the gap size between the guide vane products and the corresponding profile on the tooling. The gap size is detected using a standard feeler gauge with an accuracy of 0.01mm.

[0046] A detachable third limit block 201 is also provided, one side of the third limit block 201 abuts against the third standard gauge block 204 , and the other side is used to abut against the profile A2 of the side wall of the second support 402 at the bottom of the guide vane product, so as to limit the second support 402 .

[0047] After the tool is clamped once, the processing process can be self-checked by using the standard gauge block and the standard feeler gauge. The standard gauge block and the first limit block 102, the second limit block 103, and the third limit block 201 are detachable. After the self-check, they can be disassembled and directly processed for fine processing, thereby improving the final dimensional accuracy of the product and improving the processing efficiency.

[0048] A second through slot 305 is formed perpendicular to the side wall of the first through slot 304, which is close to the second limiting block 103 and is used to correspond to the bottom groove of the guide vane product. A third through slot 306 is formed on the second limiting block 103 corresponding to the second through slot 305 and connected to it. When clamping, a positioning key is set in the second through slot 305 and its corresponding bottom groove of the guide vane product through the third through slot 306 to position the guide vane product.

[0049] The base 101 is also provided with a reference hole 303 for connecting an external detection device or a processing device as a reference.

[0050] Based on the above-mentioned tooling, the method for rapid processing and testing of guide vane products of the present invention specifically includes the following steps:

[0051] S1. Set guide vane products, such as Figure 3 As shown, the side wall of the first through groove 304 close to the second limit block 103 is used as the tooling reference plane A, the bottom surface of the first through groove 304 is used as the tooling reference plane B, and the surface where the central axis of the second through groove 305 is located and is parallel to the side wall of the second through groove 305 is used as the tooling reference plane C. The tooling reference plane C coincides with the reference plane of the guide vane product, that is, the required reference plane of the product. The profile A1 of the guide vane product is matched with the first profile of the base 101, and the first support 401 is arranged in the first through groove 304. The profiles A3 and A4 of the guide vane product correspond to the second profile of the first limit block 102 and the third profile of the second limit block 103 respectively. Positioning keys are set in the second through groove 305 and the bottom groove of the guide vane product, and are locked by a locking device.

[0052] S2. Set the locking bolt 302 to fix the guide vane products, such as Figure 4 shown.

[0053] S3. Install the third limiting block 201.

[0054] S4. Set up a standard gauge block and use a standard feeler gauge to detect the gap between the standard gauge block and the corresponding surface of the guide vane product. The accuracy of the standard feeler gauge is 0.01mm. Specifically:

[0055] The profile A1 is measured by the first standard gauge block 202 and a standard feeler gauge with an accuracy of 0.01;

[0056] The profile A2 is measured by the third limit block 201, the third standard gauge block 204 and a standard feeler gauge with an accuracy of 0.01;

[0057] The profile A3 is measured by the second standard gauge block 203 and a standard feeler gauge with an accuracy of 0.01;

[0058] The profile A4 is measured by the fourth standard gauge block 205 and a standard feeler gauge with an accuracy of 0.01;

[0059] According to the same benchmark and the same clamping conditions during the processing, it can be determined that the deviations of the B1 and B2 profiles set on the side of the guide vane products are the same as those of the profiles A1 to A4. Therefore, after the self-inspection is completed, the dimensional deviations of the profiles B1 and B2 can be inferred from the test results of the profiles A1 to A4.

[0060] S5, remove the first limit block 102, the second limit block 103, the first standard gauge block 202, the second standard gauge block 203, the third standard gauge block 204 and the fourth standard gauge block 205, as shown in FIG. Figure 5 As shown, taking the tooling as the benchmark and according to the test results, the difference between the guide vane products and their required dimensions is obtained by comparison.

[0061] S6. Install the guide vane products and tooling as a whole on the CNC machine tool, use the reference hole 303 of the tooling to position and install, and process the surfaces A1, A2, A3, A4 and the surfaces B1 and B2 set on the sides of the guide vane products, so as to improve the dimensional accuracy of the product.

[0062] S7. After the fine machining is completed, the reference hole 303 of the tooling is used as a reference to establish a detection reference, and three-dimensional coordinate measurement is performed on the guide vane products to obtain specific parameters after fine machining, thereby completing the rapid machining and detection of the guide vane products.
