Description

Technical Field

[0001] The present application relates to the technical field of process manufacturing monitoring, and in particular to an anti-fatigue process method, device, equipment and medium for a fastener hole structure. Background Art

[0002] In the maintenance of aircraft and railway systems, a large number of failure forms are fatigue failures caused by stress concentration near the fastener hole structure, which greatly increases the maintenance costs. Therefore, how to reduce costs and improve the fatigue performance of fastener holes has become our main research direction.

[0003] At present, improving the fatigue performance of fastener hole structures can be done from two aspects. On the one hand, high-quality materials can be used. On the other hand, structural optimization and different anti-fatigue manufacturing process methods can be used. The use of high-quality materials to improve the fatigue performance of fastener holes requires a large investment, so people widely use structural optimization and different anti-fatigue manufacturing process methods to improve the fatigue performance of fastener holes. The process methods include: laser shock, shot peening, interference fit and cold extrusion. When improving the fatigue performance of fastener holes, it is often necessary to use a clamping device to clamp the plate where the fastener hole structure is located to reduce the occurrence of posture changes in the fastener hole structure. However, as the application time of the clamping device increases, the clamping capacity of the clamping device also decreases. Therefore, during the clamping process, the plate may slide, causing the fastener hole posture to change, resulting in poor anti-fatigue improvement of the fastener hole structure. Therefore, how to improve the processing accuracy of the fastener hole structure is a technical problem that needs to be solved urgently by technicians in this field. Summary of the invention

DETAILED DESCRIPTION

[0023] The following is combined with Figure 1 To Attachment Figure 3 This application is described in further detail.

[0024] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make modifications to the present embodiment without any creative contribution as needed, but such modifications are protected by the patent law as long as they are within the scope of the claims of the present application.

[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] In addition, the term "and / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article, unless otherwise specified, generally means that the associated objects before and after are in an "or" relationship.

[0027] The embodiments of the present application are further described in detail below in conjunction with the drawings in the specification.

[0028] In the related technology, during the anti-fatigue processing of the fastener hole structure, a clamping device is used to clamp the fastener hole structure to reduce the occurrence of posture changes. However, since the fastener hole structure may slide during the clamping process, the anti-fatigue processing effect may be poor due to the posture change.

[0029] The embodiment of the present application provides an anti-fatigue process method for a fastener hole structure. The process method is applied to an anti-fatigue processing technology for a fastener hole structure. The anti-fatigue processing technology includes: Step 1: Micro shot peening of fastener hole structure; Step 2: cold extrusion of the slotted bushing on the processed fastener hole structure; Step 3: Fix the fastener hole structure of the slit bushing after cold extrusion treatment to the fastener by means of interference fit.

[0030] In order to solve the technical problems existing in each of the above steps, the present application provides an anti-fatigue process method, device, equipment and medium for a fastener hole structure, by acquiring processing image information of historical processing steps in real time, the historical processing steps are step one, step two and step three within the historical cycle time period, and processing the processed image information to determine the position change information corresponding to the fastener hole structure located at the clamping device in step one, step two and step three within the historical cycle time period, and performing clamping judgment detection on the clamping device based on the position change information to determine whether the fastener hole structure located at the clamping device has slippage. If the fastener hole structure located outside the clamping device has slippage, clamping prediction analysis is performed on the fastener hole structure based on the position change information to obtain the clamping positions of the clamping device clamping the fastener hole structure in the current step one, step two and step three, respectively.

[0031] When performing anti-fatigue processing on the fastener hole structure, laser impact, shot peening, interference fit and cold extrusion processes are used. Laser shock is a high-tech technology that uses plasma shock waves generated by strong laser beams to improve the fatigue resistance, wear resistance and corrosion resistance of fastener hole structures. It has outstanding advantages such as non-contact, no heat-affected zone, strong controllability and significant strengthening effect.

[0032] Shot peening is a means of improving the fatigue strength of materials. By forming a residual compressive stress layer and a work hardening layer near the surface, it can delay crack initiation and reduce the crack propagation rate, thereby improving the fatigue strength of the fastener hole structure. However, it also increases the surface roughness and may reduce its fatigue life.

[0033] In the embodiment of the present application, a new shot peening process is used to process the fastener hole structure, and the shot peening uses spherical particles (called micro-shot or fine particles) with a size of 0.01-0.2 mm to impact the surface. Compared with the sample treated with conventional shot peening, under the same air pressure and coverage area, the surface roughness of the sample treated with micro-shot peening is reduced, and the treated surface obtains a higher residual compressive stress.

[0034] As a process for improving the fatigue life of fastener holes, cold extrusion technology involves inserting a mandrel with a bushing into the hole. When the mandrel passes through the bushing, plastic deformation will occur around the hole. When the mandrel is completely passed through, the area around the hole returns to its initial elastic state, and the plastic zone moves backward, forming a residual stress area around the hole, which reduces the total stress amplitude and enhances the fatigue performance of the hole structure. However, it is difficult for traditional cold extrusion processes to produce uniform residual stress. The shot peening process and electromagnetic cold extrusion technology used in this application can both improve the fatigue life of fastener holes. The former not only reduces the surface roughness, but also obtains higher residual stress. The latter not only avoids damage to the hole wall caused by direct contact, but also produces uniform residual stress.

[0035] The process method is performed by an electronic device, which can be a server or a terminal device, wherein the server can be an independent physical server, a server cluster or a distributed system composed of multiple physical servers, or a cloud server that provides cloud computing services. The terminal device can be a smart phone, a tablet computer, a laptop computer, a desktop computer, etc., but is not limited thereto. The terminal device and the server can be directly or indirectly connected via wired or wireless communication, and the embodiments of the present application are not limited thereto.

[0036] Combination Figure 1 , Figure 1 A schematic diagram of a process flow of an anti-fatigue process method for a fastener hole structure provided in an embodiment of the present application, such as Figure 1 As shown, the method includes step S10, step S11, step S12, step S13, step S14 and step S15, wherein: Step S10: Obtaining processed image information of historical processing steps.

[0037] Among them, the historical processing steps are step one, step two and step three within the historical cycle time period.

[0038] For the embodiments of the present application, the historical period time period refers to a time period with clear start and end time points, and the settings of the start time point and the end time point are pre-set by field personnel based on specific circumstances.

[0039] In the embodiment of the present application, a corresponding shooting device is set during the processing process to capture and collect the processed image information, and store it in the database together with the corresponding processing steps and timestamps. Then, when it is necessary to review the historical data, the query conditions (such as time range, processing steps, etc.) are entered through the query interface provided by the system, and the system can automatically retrieve and display the relevant image information.

[0040] Step S11: Processing the processed image information to determine the position change information corresponding to the fastener hole structure located at the clamping device in step 1, step 2 and step 3 within the historical cycle time period.

[0041] Specifically, a first image set corresponding to step one, a second image set corresponding to step two, and a third image set corresponding to step three within a historical period time period are determined based on the processed image information, and the first image set, the second image set, and the third image set are arranged according to the time trend to obtain a first image sequence corresponding to the first image set, a second image sequence corresponding to the second image set, and a third image sequence corresponding to the third image set, and image map point calibration is performed on the first image sequence, the second image sequence, and the third image sequence to determine the first structure map point and the first device map point corresponding to each image in the first image sequence, the second structure map point and the second device map point corresponding to each image in the second image sequence, and the third structure map point and the third device map point corresponding to each image in the third image sequence; and the position change information corresponding to the fastener hole structure located at the clamping device in steps one, step two, and step three within the historical period time period is determined based on the first structure map point and the first device map point, the second structure map point and the second device map point, and the third structure map point and the third device map point.

[0042] Specifically, the first position change information of the fastener hole structure and the clamping device at different times in the first image sequence is determined according to the first structure map point and the first device map point, and then the second position change information of the fastener hole structure and the clamping device at different times in the second image sequence is determined according to the second structure map point and the second device map point. Then, the third position change information of the fastener hole structure and the clamping device at different times in the third image sequence is determined according to the third structure map point and the third device map point. Then, the first position change information, the second position change information and the third position change information are combined to determine the position change information corresponding to the fastener hole structure located at the clamping device in steps one, two and three within the historical period time period.

[0043] In the embodiments of the present application, image map points are in the fields of image processing, computer vision, and augmented reality, and generally refer to specific points on an image that are identified, marked, or used for positioning. Image map points have uniqueness, recognizability, stability, and correlation, among which: Uniqueness: Image map points are generally unique, that is, each point represents a specific position or feature in the image. Recognizability: These points generally have significant features, such as corner points, edge points, areas with rich textures, etc., making them easy to be recognized and extracted by algorithms. Stability: When the image undergoes a certain range of transformations (such as rotation, scaling, translation, etc.), the image map points should be able to maintain relatively stable positions and features to facilitate subsequent matching and tracking. Correlation: There may be a certain correlation between image map points, such as being connected or influenced by each other in some way (such as geometric relationships, color relationships, etc.), thereby forming a more complex image structure or model.

[0044] Step S12: performing a clamping determination test on the clamping device based on the position change information to determine whether there is a slipping phenomenon in the fastener hole structure located at the clamping device.

[0045] Specifically, the first position change information, the second position change information and whether the position change information is empty are determined respectively. If they are not empty, it is determined that the fastener hole structure located at the clamping device has slippage. If they are empty, it is determined that the fastener hole structure located at the clamping device does not have slippage.

[0046] Step S13: If the fastener hole structure at the clamping device has a slipping phenomenon, a clamping prediction analysis is performed on the fastener hole structure based on the position change information to obtain the clamping positions of the fastener hole structure in the current step one, step two and step three respectively.

[0047] Specifically, based on the position change information, the clamping prediction analysis of the fastener hole structure is performed to obtain the clamping positions of the clamping device clamping the fastener hole structure in the current step one, step two and step three, respectively, including: determining the initial position change information and the first time information of the first slippage phenomenon when the clamping device clamps the fastener hole structure in each step according to the position change information, as well as the non-initial position change information and the second time information of the current non-first slippage phenomenon, performing data planning on the first time information and the initial position change information according to the clamping time point, and obtaining the initial change coefficient corresponding to the initial position change information in each step, The second time information and the non-initial position change information are data planned according to the clamping time point to obtain the non-initial change coefficient corresponding to the non-initial position change information in each step, and the initial change coefficient and the non-initial change coefficient are sorted according to step one, step two and step three to obtain the first coefficient sequence corresponding to step one, the second coefficient sequence corresponding to step two and the third coefficient sequence corresponding to step three, and the first coefficient sequence, the second coefficient sequence and the third coefficient sequence are periodically predicted and analyzed to obtain the clamping positions of the clamping device clamping the fastener hole structure in the current steps one, two and three, respectively.

[0048] In an embodiment of the present application, the data planning method of the initial change coefficient and the non-initial change coefficient is the ratio of the position change information to the time information.
