[0042] The present application can realize the tooling for rapid processing and detection of guide vane products, as shown in Figure 1 and Figure 2 The tooling includes a base 101 and first and second limiting blocks 102 and 103 arranged on both sides of the base 101. The guide vane product is provided with first and second supports 401 and 402 at the bottom, which are used as support structures for fitting with the tooling.

[0043] The upper surface of the base 101 is provided with a first through slot 304 and a first profile as a positioning structure. The height of the end of the base 101 close to the first limiting block 102 is greater than that of the other end. The first profile is arranged at an inclined angle on one end of the base 101, which is adapted to the angle of the bottom of the guide vane product. The first profile is used to fit with the profile A1 at the bottom of the second support 402 of the guide vane product. The first through slot 304 is located at the other end of the base 101 and is used to arrange the first support 401 of the guide vane product. A locking device is arranged in the first through slot 304 and is used to fix the guide vane product. In this embodiment, a threaded hole is arranged in the sidewall of the first through slot 304, and a locking bolt 302 is arranged in the threaded hole. The first support 401 is pressed tightly by tightening the locking bolt 302, thereby fixing the guide vane product.

[0044] The first and second limiting blocks 102 and 103 are connected with the base 101 by mounting screws 301. The first limiting block 102 is higher than the base 101 and has a second profile on the side close to the base 101. The second limiting block 103 is higher than the base 101 and has a third profile on the side close to the base 101. The second and third profiles are respectively adapted to the profiles A3 and 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 the profile A1. A second standard gauge block 203 is arranged between the second profile and the profile A3. A third standard gauge block 204 is arranged below the second standard gauge block 203. A fourth standard gauge block 205 is arranged between the third profile and the profile A4. The standard gauge blocks can be made into different specifications according to the use, such as the theoretical thickness of the first standard gauge block 202, which can be made into 2.8mm, 2.9mm, 3.0mm, 3.1mm, etc. The thickness of the remaining standard gauge blocks can also be set according to the needs, so as to measure the gap size between the guide vane product and the corresponding profile on the tooling. The gap size is detected by using a standard plug gauge with a precision of 0.01mm.

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

[0047] After one clamping, this fixture can perform self-inspection during the machining process using standard gauge blocks and standard feeler gauges. The standard gauge blocks and the first limit block 102, the second limit block 103, and the third limit block 201 are detachable. After self-inspection, they can be disassembled and directly used for fine finishing, which improves the final dimensional accuracy of the product and increases the machining efficiency.

[0048] The first through groove 304 has a second through groove 305 perpendicular to the side wall of the second limiting block 103, which corresponds to the bottom groove of the guide vane product. The second limiting block 103 has a third through groove 306 corresponding to the second through groove 305 and communicating with it. During clamping, the third through groove 306 is used to set positioning keys in the second through groove 305 and the corresponding bottom groove of the guide vane product to position the guide vane product.

[0049] The base 101 is also provided with a reference hole 303, which is used as a reference to connect external testing devices or processing devices.

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

[0051] S1. Set up guide vane type products, such as Figure 3 As shown, the side wall of the first through groove 304 near the second limiting block 103 is used as the tooling reference surface A, the bottom surface of the first through groove 304 is used as the tooling reference surface B, and the surface parallel to the side wall of the second through groove 305 where the central axis of the second through groove 305 is located is used as the tooling reference surface C. The tooling reference surface C coincides with the reference surface of the guide vane product, which is the product requirement reference surface. The profile A1 of the guide vane product corresponds to the first profile of the base 101. The first support 401 is set in the first through groove 304. The profiles A3 and A4 of the guide vane product correspond to the second profile of the first limiting block 102 and the third profile of the second limiting block 103, respectively. A positioning key is set in the second through groove 305 and the bottom groove of the guide vane product, and locked by a locking device.

[0052] S2. Install 302 locking bolts to fix guide vane products, such as... Figure 4 As shown.

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

[0054] S4. Set up a standard gauge block and use a standard feeler gauge to check 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 the standard plug 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 the standard plug gauge with an accuracy of 0.01;

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

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

[0059] According to the same reference and the same clamping condition in the machining process, it can be determined that the deviations of the B1 and B2 profiles arranged on the side surface of the guide vane product are the same as those of the profiles A1 to A4. Therefore, the size deviation of the profiles B1 and B2 is inferred from the detection results of the profiles A1 to A4 after self-checking.

[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 Figure 5 The gap between the guide vane product and the required size is obtained by comparison according to the detection results.

[0061] S6, the guide vane product and the tooling are installed on the numerical control machine tool as a whole, the reference hole 303 of the tooling is used for positioning and installation, the profiles A1, A2, A3, A4 and the profiles B1 and B2 arranged on the side surface of the guide vane product are machined, so as to improve the size precision of the product.

[0062] S7, after finish machining, taking the reference hole 303 of the tooling as a reference, a detection reference is established, the guide vane product is measured by a three-coordinate measuring machine, the specific parameters after finish machining are obtained, and the rapid machining and detection of the guide vane product are completed.
