Description

Technical Field

[0001] This application relates to the technical field of CNC machining and manufacturing, and in particular to a segmented machining method and related apparatus for blade ring rectifiers. Background Technology

[0002] Blade ring rectifiers are generally made of high-temperature alloys and are a component of aero engines. With the development of the aerospace industry, the requirements for blade ring rectifiers, as an important component of aero engines, are becoming increasingly stringent.

[0003] The relevant processing method for blade ring rectifiers is: ring-forming processing, which involves treating the blank of the blade ring rectifier as a whole and turning the blank multiple times to perform ring-forming processing to obtain the formed blade ring rectifier. This method has relatively low efficiency.

[0004] Therefore, there is an urgent need to design a segmented processing method and related equipment for blade ring rectifiers to overcome the shortcomings of existing technologies. Summary of the Invention

[0005] Therefore, it is necessary to provide a method and related apparatus for efficiently processing segmented blade ring rectifiers in response to the above-mentioned technical problems.

[0006] The objective of this application is achieved through the following technical solution:

[0007] In a first aspect, this application provides a segmented processing method for an impeller ring rectifier, the impeller ring rectifier comprising multiple segmented rectifiers, the method comprising: acquiring theoretical characteristic information of each segmented rectifier; acquiring a processing strategy for each segmented rectifier based on the theoretical characteristic information of each segmented rectifier; and controlling a processing device to process the segmented blanks corresponding to each segmented rectifier based on the processing strategy of each segmented rectifier, so as to obtain the impeller ring rectifier.

[0008] The beneficial effects of this technical solution are as follows: Based on the theoretical characteristic information of the segmented rectifier, a processing strategy is obtained for machining the segmented blank. Compared to machining the entire ring, this method is less prone to toolpath interference, has better tool accessibility, and produces a high-gloss finish on the machined segmented rectifier, thus improving the machining quality of the blade ring rectifier. Because toolpath interference is less likely, the forward tilt angle between the tool and the contact point can be maintained at a good position, which helps maintain tool rigidity, thereby reducing tool wear and reducing processing costs. The machining of the segmented rectifier eliminates the flipping step (as in conventional ring machining of blade ring rectifiers), reducing the overall difficulty of machining the blade ring rectifier during mass production and thus improving its production efficiency.

[0009] Furthermore, in the actual segmented manufacturing process of the blade ring rectifier, the above method first processes the segmented rectifiers. This can be understood as meaning that if a processing defect occurs in any segmented rectifier, it will not affect the other segmented rectifiers in the blade ring rectifier. Users can repair or reprocess the defective segmented rectifiers, which saves costs. In the application scenario of large-scale blade ring rectifier production, a small number of defects can affect the blade ring rectifiers processed by the whole ring. However, in this application, only a small number of defective segmented rectifiers will be affected, which is more conducive to the company's control over defects and reduces the company's production costs.

[0010] In summary, the segmented machining method for the blade ring rectifier described above can produce a blade ring rectifier comprising multiple segments. Because it is part of a ring of segmented blade ring rectifiers, the machining process of each segment can avoid flipping, reducing the overall difficulty of blade ring rectifier machining and improving production efficiency. Furthermore, it minimizes toolpath interference during segmented machining, improves tool accessibility of the machining equipment, and enhances the machining quality of the blade ring rectifier. The segmented machining method also facilitates defect control for enterprises, reducing production costs.

[0011] In some optional embodiments, the method further includes: for each of the segmented rectifiers, performing the following processing: controlling a detection device to perform precision detection on the segmented rectifier to obtain a first detection result of the segmented rectifier; and determining whether the blade ring rectifier is qualified based on each of the first detection results.

[0012] The beneficial effect of this technical solution is that, compared to performing precision testing on the entire ring (of a machined blade ring rectifier), this application performs precision testing on each segmented rectifier after processing, enabling real-time quality control. In enterprises, output and quality are complementary; on the one hand, they promote each other and improve together; on the other hand, they constrain and restrict each other, being interdependent and inseparable. By raising the quality requirements for each segmented rectifier, lean production can be promoted, and enterprise production efficiency can be improved.

[0013] In some optional embodiments, the control and detection device performs accuracy detection on the segmented rectifier to obtain a first detection result of the segmented rectifier, including: acquiring in-machine measurement path information based on the theoretical characteristic information of the segmented rectifier; controlling the in-machine measurement device to perform accuracy detection on the segmented rectifier based on the in-machine measurement path information to acquire the actual characteristic information of the segmented rectifier; calculating a first similarity between the theoretical characteristic information and the actual characteristic information of the segmented rectifier; when the first similarity is greater than a first preset similarity threshold, determining that the first detection result is used to indicate that the segmented rectifier is a qualified product; when the first similarity is not greater than the first preset similarity threshold, determining that the first detection result is used to indicate that the segmented rectifier is a defective product.

[0014] The beneficial effect of this technical solution is that it obtains in-machine measurement path information based on the theoretical characteristic information of the segmented rectifier. The measurement path can be reasonably planned according to the theoretical characteristic information of each segmented rectifier, which improves the efficiency and accuracy of obtaining the actual characteristic information of each segmented rectifier.

[0015] In some optional embodiments, the method further includes: when the first detection result indicates that the segmented rectifier is unqualified, detecting whether the segmented rectifier meets preset repair conditions; when the segmented rectifier meets the preset repair conditions, repairing the segmented rectifier; when the segmented rectifier does not meet the preset repair conditions, re-acquiring the segmented rectifier based on the processing strategy corresponding to the segmented rectifier.

[0016] The beneficial effect of this technical solution lies in the fact that by pre-setting repair conditions, some repairable segmented rectifiers can be reused, thereby reducing production costs and saving raw material expenditures. This transforms passive cost-saving into "saving is efficiency," allowing segmented rectifiers that meet the repair conditions to be put back into service, significantly reducing production expenditures and laying a solid foundation for enterprise expansion. When a segmented rectifier does not meet the pre-set repair conditions, it can be re-acquired based on the processing strategy corresponding to the segmented rectifier that does not meet the pre-set repair conditions, eliminating the need to recalculate the processing strategy and resulting in high efficiency.

[0017] In some optional embodiments, when each of the first detection results indicates that the segmented rectifier is qualified, the method further includes: obtaining a second detection result of the blade ring rectifier based on the actual characteristic information of each of the segmented rectifiers, wherein the second detection result is used to indicate whether the blade ring rectifier is qualified.

[0018] The beneficial effect of this technical solution is that, relatively speaking, the process of whole-ring inspection is more complex than that of segmented (rectifier) ​​inspection, which reduces the efficiency of obtaining blade ring rectifiers. Therefore, compared with the related method of directly inspecting the whole ring (of the blade ring rectifier with whole-ring processing), this embodiment further inspects the blade ring rectifier only when the first inspection results indicate that the segmented rectifier is qualified. If the first inspection result is unqualified, the second inspection result will not be obtained, thus improving the efficiency of accuracy inspection.

[0019] In some optional embodiments, obtaining the second detection result of the blade ring rectifier based on the actual feature information of each segmented rectifier includes: obtaining the actual feature information of the blade ring rectifier based on the actual feature information of each segmented rectifier; calculating the second similarity between the theoretical feature information and the actual feature information of the blade ring rectifier; determining that the second detection result is used to indicate that the blade ring rectifier is a qualified product when the second similarity is greater than the second preset similarity threshold; and determining that the second detection result is used to indicate that the blade ring rectifier is a defective product when the second similarity is not greater than the second preset similarity threshold.

[0020] The beneficial effect of this technical solution is that it uses the actual characteristic information of each segment rectifier to obtain the actual characteristic information of the blade ring rectifier, eliminating the need to obtain the actual characteristic information of the entire blade ring rectifier, thus improving the production efficiency of the blade ring rectifier.

[0021] In some optional embodiments, the control processing equipment processes the segmented blanks corresponding to each segmented rectifier, including: using the processing equipment to perform cutting processing from the air inlet end of the flow channel to the air outlet end of the flow channel of the segmented blank.

[0022] The beneficial effects of this technical solution are that, during cutting from the inlet to the outlet of the flow channel, the cutting tool of the machining equipment is less prone to toolpath interference, and the forward tilt angle between the tool and the contact point can be maintained at a good position, which helps to maintain the rigidity of the tool and thus reduces tool wear. In addition, since this application performs segmented machining on segmented blanks to obtain multiple segmented rectifiers, compared to machining the entire annular blade ring rectifier, the cutting can be initiated from inside the blades (from the inlet to the outlet of the flow channel), resulting in smaller fluctuations in cutting force at the cutting contact point.

[0023] Secondly, this application also provides a processing apparatus for an impeller ring rectifier, the processing apparatus comprising:

[0024] The feature acquisition module is used to acquire the theoretical feature information of each segmented rectifier;

[0025] The strategy acquisition module is used to acquire the processing strategy of each segmented rectifier based on the theoretical characteristic information of each segmented rectifier;

[0026] The processing control module is used to control the processing equipment to process the segmented blanks based on the processing strategy of each segmented rectifier, so as to obtain each segmented rectifier of the blade ring rectifier.

[0027] Thirdly, this application also provides an electronic device, which includes a memory and a processor, wherein the memory stores a computer program, and the processor executes the computer program to implement the steps of the method described in any of the first aspects.

[0028] Fourthly, this application also provides a computer-readable storage medium storing a computer program that, when executed by a processor, implements the steps of the method described in any of the first aspects. Attached Figure Description

[0039] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0040] The terms “first,” “second,” “third,” “fourth,” etc. (if present) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein. Furthermore, the terms “comprising” and “corresponding to,” and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0041] First, a brief description of the application areas of this application will be given.

[0042] Blade ring rectifiers are generally made of high-temperature alloys and are used in the field of aero-engine technology. The blade ring rectifier is a component of an aero-engine.

[0043] An aircraft engine is a device primarily used to generate thrust or pull to propel an aircraft forward. Besides generating forward force, it also provides electricity to the aircraft's electrical equipment and air supply to systems such as air conditioning. Due to the demands of flight, aircraft engines are generally designed to be quite lightweight, yet require high operational efficiency and extremely low failure rates, resulting in stringent design and manufacturing processes. Key performance indicators for aircraft engines include fuel consumption rate, thrust, and thrust-to-weight ratio. Air-dependent engines include piston engines, aero gas turbines, ramjet engines, and detonation engines. Aero gas turbines include turbojet engines, turbofan engines, turboprop engines, propfan engines, and turboshaft engines.

[0044] The bladed ring rectifier is ring-shaped, and its outer ring can be integrated with the engine casing. Multiple blades are located within the outer ring. The bladed ring rectifier is formed by brazing the blades to the outer ring, or by machining it as a single piece. As the performance requirements of aero engines continue to increase, the manufacturing difficulty of its components is also constantly rising.

[0045] Because the blade ring rectifier is a key aerospace component that operates under extreme environmental conditions (high temperature, high pressure, strong impact), it uses high-strength heat-resistant materials. The blade shape is complex, the flow channel space formed by the blade is narrow, the machining accessibility of the machining tools is poor, the tool connection and machining chatter problems are serious, the machining efficiency is low, the tool cost is high, and the blade accuracy and surface quality are difficult to guarantee.

[0046] The application field of the segmented processing method for blade ring rectifiers in this application embodiment is not limited. In addition to aero engines, the segmented processing method for blade ring rectifiers can also be applied to other applicable fields such as aerospace engines, aero-engines, range hoods, and flue gas turbines.

[0047] (Method Implementation Examples)

[0048] See Figure 1 and Figure 2 , Figure 1 A schematic diagram of a segmented rectifier provided in this application is shown. The segmented rectifier includes multiple blades and an arc-shaped outer ring integrally formed with the multiple blades.

[0049] Figure 2 A schematic flowchart of a segmented processing method for an impeller rectifier provided in this application is shown.

[0050] The blade ring rectifier includes multiple segmented rectifiers, and the method includes:

[0051] Step S101: Obtain the theoretical characteristic information of each segmented rectifier;

[0052] Step S102: Based on the theoretical characteristic information of each segmented rectifier, obtain the processing strategy for each segmented rectifier;

[0053] Step S103: Based on the processing strategy of each segmented rectifier, control the processing equipment to process the segmented blanks corresponding to each segmented rectifier to obtain the blade ring rectifier.

[0054] Therefore, a processing strategy based on the theoretical characteristic information of the segmented rectifier is used to process the segmented blank. Compared with the whole ring processing, it is less likely to produce toolpath interference, the tool accessibility of the processing equipment is better, and the processed segmented rectifier has high brightness, thus improving the processing quality of the blade ring rectifier. Since it is less likely to produce toolpath interference, the forward tilt angle of the tool and the contact point can be kept in a good position, which is conducive to maintaining the rigidity of the tool, thereby reducing tool wear and reducing processing costs. The processing of segmented rectifiers eliminates the flipping step (in conventional blade ring rectifier processing), which reduces the overall difficulty of blade ring rectifier processing when performing mass production, thereby improving the production efficiency of blade ring rectifiers.

[0055] Furthermore, in the actual segmented manufacturing process of the blade ring rectifier, the above method first processes the segmented rectifiers. This can be understood as meaning that if a processing defect occurs in any segmented rectifier, it will not affect the other segmented rectifiers in the blade ring rectifier. Users can repair or reprocess the defective segmented rectifiers, which saves costs. In the application scenario of large-scale blade ring rectifier production, a small number of defects can affect the blade ring rectifiers processed by the whole ring. However, in this application, only a small number of defective segmented rectifiers will be affected, which is more conducive to the company's control over defects and reduces the company's production costs.

[0056] In summary, the segmented machining method for the blade ring rectifier described above can produce a blade ring rectifier comprising multiple segments. Because it is part of a ring of segmented blade ring rectifiers, the machining process of each segment can avoid flipping, reducing the overall difficulty of blade ring rectifier machining and improving production efficiency. Furthermore, it minimizes toolpath interference during segmented machining, improves tool accessibility of the machining equipment, and enhances the machining quality of the blade ring rectifier. The segmented machining method also facilitates defect control for enterprises, reducing production costs.

[0057] In this embodiment, the source of the theoretical characteristic information for each segmented rectifier is not specifically limited. The theoretical characteristic information for each segmented rectifier can be obtained in any way. This flexible selection of the method for obtaining the theoretical characteristic information for each segmented rectifier facilitates meeting various needs in practical applications.

[0058] The theoretical characteristic information of the segmented rectifier can be obtained by inputting the theoretical characteristic information of the blade ring rectifier into a trained rectifier segmentation model. This means that the rectifier segmentation model can utilize the input theoretical characteristic information of the blade ring rectifier and the desired number of segments to output the theoretical characteristic information of each segmented rectifier. The desired number of segments for each blade ring rectifier can be 3, 4, or 6; this embodiment does not impose any limitation.

[0059] The rectifier segmentation model can be obtained by training a selected initial neural network. Of course, the rectifier segmentation model can also be a function model formed through multiple adjustments; this embodiment does not impose specific restrictions on the form of the rectifier segmentation model. This embodiment can pre-train the selected initial neural network so that, during implementation, the theoretical characteristic information of the blade ring rectifier and the desired number of segments can be input into the rectifier segmentation model. Through model calculation, the theoretical characteristic information of each segmented rectifier can be obtained, resulting in a high level of intelligence.

[0060] For example, the theoretical characteristic information of the blade ring rectifier can be directly obtained using its design files (e.g., 3D design files, such as SLDASM&SLDPRT models, UG models, etc.). Alternatively, when 3D information of the blade ring rectifier is obtained (e.g., CT scan information, X-ray scan information, MRI scan information, ultrasonic scan information, 3D point cloud data, 3D patch data, 3D contour data, etc.), the theoretical characteristic information of the blade ring rectifier can be obtained based on this 3D information. Furthermore, when image information (images or videos) of the blade ring rectifier is obtained, a preset image processing model can be used to extract features from the image information to obtain the theoretical characteristic information of the blade ring rectifier. The blade ring rectifier can be a sample of the blade ring rectifier that the user expects to process. Simultaneously, the theoretical characteristic information of the blade ring rectifier can also be obtained from local storage devices, servers, or the cloud; this embodiment does not specifically limit the source of the theoretical characteristic information of the blade ring rectifier.

[0061] In addition, the theoretical characteristic information of each segmented rectifier can be obtained from existing information directly from local storage devices, servers, or the cloud. The characteristic information of each segmented rectifier can be the same or different, and users can set different or the same characteristic information for segmented rectifiers according to their own needs.

[0062] The theoretical characteristic information of the segmented rectifier may include the material of the blade ring rectifier, the number of blades, the curvature of the blades, the positional relationship between each blade, the positional relationship between the blades and the outer ring, the sector angle of the outer ring, the length of the blades, the minimum gap between two adjacent blades, the transition radius between the blades and the upper and lower flow channels, etc. This embodiment does not specifically limit the types of theoretical characteristic information of the segmented rectifier.

[0063] For example, the material of the segmented rectifier can be TC4, TC11 or TC18; the number of blades can be 10, 20 or 40; the length of the blades can be 20mm, 40mm or 80mm; the minimum gap between two adjacent blades can be 6mm, 8mm or 12mm; the transition radius between the blades and the upper and lower flow channels can be 1mm, 1.1mm or 3mm; the radii of the blades can be, for example, 80°, 110° or 120°; and the fan angle of the outer ring can be, for example, 40°, 60° or 170°.

[0064] The machining strategy may include at least one of the following: machining area, machining allowance, tool type, tool size, and machining method. This application does not limit the machining area, machining allowance, tool type, tool size, and machining method. The machining area may be multiple different areas to be machined in the segmented rectifier; for example, the machining area may be the blades or the area of ​​the outer ring facing the blades. The machining allowance may be, for example, 0.1mm, 0.4mm, or 1mm. The tool type may be, for example, a ball end mill, an end mill, or a face mill. The tool size may be, for example, a radius of 1mm, 2mm, or 4mm. The machining method may be, for example, plunge milling, layer milling, or line cutting.

[0065] The segmented blanks in this embodiment can be obtained using various existing processing methods, such as wire EDM. Generally, wire EDM can achieve a processing accuracy of ±0.01 to ±0.02 mm, and segmented blanks obtained using wire EDM can improve the processing accuracy and efficiency of the segmented rectifier. Segmented blanks can also be obtained, for example, through die forging. This embodiment does not limit the method of obtaining the segmented blanks.

[0066] Once each segment rectifier is manufactured, the blade ring rectifier is obtained. When using the blade ring rectifier, the outer ring of each segment rectifier is attached close to the casing of the aero-engine. The position of each segment rectifier can be restricted using existing methods such as snap-fitting, welding, and riveting, utilizing the casing or its auxiliary components.

[0067] See Figure 3 , Figure 3 A partial flowchart of another segmented manufacturing method for a blade ring rectifier provided in this application is shown.

[0068] In some optional embodiments, the method may further include performing the following processing for each of the segmented rectifiers:

[0069] Step S104: Control the detection equipment to perform accuracy detection on the segmented rectifier to obtain the first detection result of the segmented rectifier;

[0070] Step S105: Based on each of the first detection results, determine whether the blade ring rectifier is qualified.

[0071] Therefore, compared to performing precision testing on the entire ring (of the manufactured blade ring rectifier), this application performs precision testing on each segmented rectifier after processing, enabling real-time quality control. In enterprises, output and quality are complementary; they promote each other and improve together, while also constraining and limiting each other. They are interdependent and inseparable. By raising the quality requirements for each segmented rectifier, lean production can be promoted, improving the enterprise's production efficiency.

[0072] The first inspection result can be "qualified," "good," "unqualified," "poor," "blade size generally too large," "blade size very large," "blade clearance generally too small," etc., or it can be a result that can distinguish the quality of the segmented rectifier, such as "high-grade," "medium-grade," or "low-grade." The first inspection result can be represented by one or more of the following: Chinese characters, letters, numbers, symbols, and special symbols. For example, when the first inspection result of all segmented rectifiers is "high-grade," the blade ring rectifier can be determined to be qualified; when the first inspection result of one of the multiple segmented rectifiers is "blade size generally too large," the blade ring rectifier can be determined to be unqualified.

[0073] Furthermore, the accuracy testing of the segmented rectifier can be performed by: automatically measuring the segmented rectifier using in-machine measurement equipment, or by performing manual or semi-manual accuracy testing using measuring instruments.

[0074] In-machine measurement (OMM) is a measurement method that uses the hardware of a CNC machine tool, along with corresponding measuring tools and software, to measure the geometric features of a part on the CNC machine tool. The hardware may include machine tool probes, machine tool tool setters, etc., while the software may include macro programs, dedicated 3D measurement software, etc. Besides measuring part dimensions and accuracy, OMM can also be used for workpiece alignment, tool breakage detection, machine tool health monitoring, machining error compensation, and parameter setting. It has significant guiding significance for improving machining accuracy and constructing large closed-loop systems, especially for complex curved surfaces; the more complex the workpiece and the higher the accuracy requirements, the more obvious its advantages become. Based on the measurement method (whether the probe directly contacts the workpiece), OMM can be divided into three categories: contact, non-contact, and composite. This application does not impose any restrictions on these categories.

[0075] See Figure 4 , Figure 4 A flowchart illustrating a first detection result acquisition method provided in this application is shown.

[0076] In some optional embodiments, step S104 may include:

[0077] Step S201: Based on the theoretical characteristic information of the segmented rectifier, obtain the in-machine measurement path information;

[0078] Step S202: Based on the on-machine measurement path information, control the on-machine measurement device to perform accuracy detection on the segmented rectifier and obtain the actual characteristic information of the segmented rectifier;

[0079] Step S203: Calculate the first similarity between the theoretical and actual characteristic information of the segmented rectifier;

[0080] Step S204: When the first similarity is greater than the first preset similarity threshold, determine that the first detection result is used to indicate that the segmented rectifier is a qualified product;

[0081] Step S205: When the first similarity is not greater than the first preset similarity threshold, the first detection result is determined to indicate that the segmented rectifier is a defective product.

[0082] Therefore, by acquiring in-machine measurement path information based on the theoretical characteristic information of segmented rectifiers, the measurement path can be rationally planned according to the theoretical characteristic information of each segmented rectifier, thereby improving the efficiency and accuracy of acquiring the actual characteristic information of each segmented rectifier.

[0083] Especially when there are differences in the theoretical characteristic information between two or more segmented rectifiers, the corresponding in-machine measurement path information can be obtained based on the theoretical characteristic information of all segmented rectifiers, which has strong applicability to different segmented rectifiers.

[0084] The actual characteristic information of the segmented rectifier may include the material of the blade ring rectifier, the number of blades, the curvature of the blades, the positional relationship between each blade, the positional relationship between the blades and the outer ring, the sector angle of the outer ring, the length of the blades, the minimum gap between two adjacent blades, and the transition radius between the blades and the upper and lower flow channels. This embodiment does not specifically limit the types of actual characteristic information of the segmented rectifier. Generally speaking, the types of actual characteristic information and theoretical characteristic information of the segmented rectifier are the same, which is beneficial for calculating the similarity between the two.

[0085] Specifically, based on the theoretical characteristic information of the segmented rectifier and according to the geometric relationship between the segmented rectifier and the probe, the feasible domain space for each measurement point of the segmented rectifier can be calculated. The approach distance, detection distance, and retraction distance of the normal direction of each measurement point can be adjusted. The probe movement path and attitude can be planned according to the feasible domain so that the on-machine measurement device (the probe) does not interfere with any solid surface other than the measurement surface of the segmented rectifier being measured during the measurement process.

[0086] Specifically, the theoretical and actual characteristic information of the segmented rectifier can be input into the first similarity model to output the corresponding predicted similarity as the first similarity. This embodiment does not limit the first preset similarity threshold; it can be 85%, 88%, or 95%.

[0087] It is understandable that the first similarity model refers to the first similarity output using the theoretical and actual feature information of the input segmented rectifier. The first similarity model can be obtained by training a selected initial neural network. Of course, the first similarity model can also be a function model formed through multiple adjustments; this embodiment does not impose specific limitations on the form of the first similarity model. This embodiment can pre-train the selected initial neural network so that, during implementation, the theoretical and actual feature information of the segmented rectifier can be input into the first similarity model, and the first similarity can be obtained through model calculation, demonstrating a relatively high level of intelligence.

[0088] See Figure 5 , Figure 5 A partial flowchart of another segmented processing method for an impeller rectifier provided in this application is shown.

[0089] In some optional embodiments, the method may further include:

[0090] Step S106: When the first detection result indicates that the segmented rectifier is unqualified, detect whether the segmented rectifier meets the preset repair conditions;

[0091] Step S107: When the segmented rectifier meets the preset repair conditions, the segmented rectifier is repaired.

[0092] Step S108: When the segmented rectifier does not meet the preset repair conditions, the segmented rectifier is re-acquired based on the processing strategy corresponding to the segmented rectifier.

[0093] Therefore, by pre-setting repair conditions, some repairable segmented rectifiers can be reused, thereby reducing production costs and saving raw material expenditures. This transforms passive cost-saving into "saving is efficiency," allowing segmented rectifiers that meet the repair conditions to be put back into service, significantly reducing production expenditures and laying a solid foundation for enterprise expansion. When a segmented rectifier does not meet the pre-set repair conditions, it can be re-acquired based on the processing strategy corresponding to the segmented rectifier that does not meet the pre-set repair conditions, without needing to recalculate the processing strategy, resulting in high efficiency.

[0094] Specifically, the preset repair conditions could be: "If the first test result is [blade clearance is generally too small], the segmented rectifier meets the preset repair conditions and is repaired; if the first test result is [low-grade product], the segmented rectifier does not meet the preset repair conditions and is scrapped." Alternatively, the preset repair conditions could be: "If the first test result is [medium-grade product], the segmented rectifier meets the preset repair conditions and is repaired; if the error measurement result of the toroidal surface is [low-grade product], the segmented rectifier does not meet the preset repair conditions and is scrapped."

[0095] In some optional embodiments, when each of the first detection results indicates that the segmented rectifier is qualified, the method may further include step S109:

[0096] Based on the actual characteristic information of each segmented rectifier, a second detection result of the blade ring rectifier is obtained, and the second detection result is used to indicate whether the blade ring rectifier is qualified.

[0097] In comparison, the process of inspecting the entire ring rectifier is more complex than that of inspecting the segmented rectifier, which reduces the efficiency of obtaining the blade ring rectifier. Therefore, compared to the related method of directly inspecting the entire ring (of the blade ring rectifier with complete ring processing), this embodiment further inspects the blade ring rectifier only when the first inspection results indicate that the segmented rectifier is qualified. If at least one of the first inspection results is unqualified, the second inspection result will not be obtained, thus improving the efficiency of accuracy inspection.

[0098] See Figure 6 , Figure 6 A flowchart illustrating a second detection result acquisition method provided in this application is shown.

[0099] In some optional embodiments, step S109 may include:

[0100] Step S301: Based on the actual characteristic information of each segmented rectifier, obtain the actual characteristic information of the blade ring rectifier;

[0101] Step S302: Calculate the second similarity between the theoretical and actual characteristic information of the blade ring rectifier;

[0102] Step S303: When the second similarity is greater than the second preset similarity threshold, the second detection result is determined to indicate that the blade ring rectifier is a qualified product;

[0103] Step S304: When the second similarity is not greater than the second preset similarity threshold, the second detection result is determined to indicate that the blade ring rectifier is a defective product.

[0104] Therefore, by using the actual characteristic information of each segment rectifier to obtain the actual characteristic information of the blade ring rectifier, it is no longer necessary to obtain the actual characteristic information of the entire blade ring rectifier, thus improving the production efficiency of the blade ring rectifier.

[0105] The actual characteristic information of the blade ring rectifier may include the material of the blade ring rectifier, the number of blades, the curvature of the blades, the positional relationship between each blade, the positional relationship between the blades and the outer ring, the sector angle of the outer ring, the length of the blades, the minimum gap between two adjacent blades, and the transition radius between the blades and the upper and lower flow channels. This embodiment does not specifically limit the types of actual characteristic information of the blade ring rectifier. Generally speaking, the types of actual characteristic information and theoretical characteristic information of the blade ring rectifier are the same, which is beneficial for calculating the similarity between the two.

[0106] In a specific application, the blade ring rectifier includes segmented rectifier A, segmented rectifier B, and segmented rectifier C. The actual characteristic information of segmented rectifier A, segmented rectifier B, and segmented rectifier C indicates the number of blades is 10, 15, and 12 respectively. This can be understood as follows: based on the actual characteristic information of segmented rectifier A, segmented rectifier B, and segmented rectifier C, the actual number of blades in the blade ring rectifier is the sum of the actual number of blades in the actual characteristic information of segmented rectifier A, segmented rectifier B, and segmented rectifier C, which is 37 blades.

[0107] Specifically, the theoretical and actual characteristic information of the blade ring rectifier can be input into the second similarity model to output the corresponding predicted similarity as the second similarity. This embodiment does not limit the second preset similarity threshold; it can be 85%, 88%, or 95%.

[0108] Understandably, the second similarity model refers to the output of a second similarity score that utilizes both the theoretical and practical feature information of the input segmented rectifier. This second similarity model can be obtained by training a selected initial neural network.

[0109] The training process for the second similarity model can be as follows:

[0110] Obtain a training set, which includes multiple training data, each of which includes theoretical feature information corresponding to a first training object and actual feature information corresponding to a second training object, as well as labeled data on the similarity between the first training object and the second training object.

[0111] Perform the following processing for each training data set:

[0112] The theoretical feature information corresponding to the first training object and the actual feature information corresponding to the second training object are input into the deep learning model to be trained to obtain the predicted data of the similarity between the first training object and the second training object.

[0113] The model parameters of the deep learning model to be trained are updated using the predicted and labeled data of the similarity between the first training object and the second training object.

[0114] Check whether the preset termination condition is met; if not, continue training; if yes, use the trained deep learning model as the second similarity model.

[0115] Therefore, by training the deep learning model to be trained using the training set, a second similarity model is obtained. This second similarity model can be trained with a large amount of training data and can predict the corresponding similarity calculation results for input data. It has a wide range of applications and a high level of intelligence. By designing and establishing an appropriate number of neural computing nodes and a multi-layered computational hierarchy, and selecting suitable input and output layers, a deep learning model to be trained can be obtained. Through the learning and optimization of this deep learning model, a functional relationship from input to output can be established. Although it cannot find a 100% accurate functional relationship between input and output, it can approximate the real-world correlation as closely as possible. The second similarity model trained in this way can obtain corresponding output data based on arbitrary input data, and the calculation results are highly accurate and reliable.

[0116] In the above embodiments, the training process of the second similarity model adopts a supervised learning method. In some other optional embodiments, the training process of the second similarity model may adopt a semi-supervised learning method or an unsupervised learning method.

[0117] The preset conditions for ending the iteration are, for example, the current iteration number (current training number) reaches a preset number (e.g., 3 times, 50 times, 1000 times), or the current loss value is less than a preset threshold.

[0118] Of course, the second similarity model can also be a function model formed through multiple adjustments. In this embodiment, the form of the second similarity model is not specifically limited. In this embodiment, the selected initial neural network can be pre-trained so that, during implementation, the theoretical and actual feature information of the segmented rectifier can be input into the second similarity model, and the second similarity can be obtained through model calculation, resulting in a relatively high level of intelligence.

[0119] It is understood that the first similarity model can also be obtained using a similar training process to the second similarity model described above, which will not be elaborated upon in this application.

[0120] In some optional embodiments, step S103 may further include: using the processing equipment to perform cutting processing from the air inlet end of the flow channel to the air outlet end of the flow channel of the segmented blank.

[0121] Therefore, when cutting from the air inlet to the exhaust outlet of the flow channel, the cutting tool of the machining equipment is less likely to cause toolpath interference, and the forward tilt angle between the cutting tool and the contact point can be kept in a good position, which helps to maintain the rigidity of the cutting tool and thus reduces the wear and consumption of the cutting tool.

[0122] In addition, since this application involves segmented machining of the blank to obtain multiple segmented rectifiers, compared to machining the entire ring-shaped blade ring rectifier, the cutting tool can be fed from inside the blade (from the inlet end of the flow channel to the outlet end of the flow channel), or from the side away from the blade ring and close to the blade towards the blade ring, so that the fluctuation of the cutting force at the cutting contact point of the tool is small.
