[0028] Through the above technical scheme, the real-time information of the hub processing is first obtained and analyzed to determine the hub position information and hub information. The pre-processing steps and subsequent processing steps of the hub are determined based on the hub position information and hub information, which provides key information for finding the cause when the hub is deformed. When the hub is deformed, the deformation condition of the hub is determined according to the real-time information of the hub processing, and the pre-processing influencing factors are determined according to the pre-processing steps, and it is determined which process in the pre-processing has a problem. The subsequent processing adjustment factors are determined according to the pre-processing factors, deformation conditions, subsequent processing steps and hub information. Through comprehensive analysis of multiple factors, scientific and accurate subsequent processing adjustments are determined, which provides an accurate processing method for the adjustment of the hub. The subsequent processing adjustment factors and hub information are combined to formulate strategies and send them to the hub processing system. The final adjustment strategy formulated in the scheme is based on the results of comprehensive analysis, which provides strong decision-making support and can formulate production plans and adjustment plans more scientifically and reasonably.

[0029] Through the above technical scheme, the wheel hub processing site image is obtained from the wheel hub processing real-time information, and then the wheel hub processing flow is obtained from the wheel hub information, which helps to judge the pre-processing and subsequent processing, and determines whether there is a processing device on site from the site image. If not, it is necessary to determine the usage information of each device from the wheel hub processing real-time information, and then determine the most recently used device from the usage information. According to the most recently used device and the wheel hub processing flow, the pre-processing steps and subsequent processing steps of the wheel hub are determined. When a processing device exists, the potential processing steps and subsequent processing steps of the wheel hub are determined directly through the processing device and the wheel hub processing flow.

[0030] Through the above technical scheme, the thermal imaging information of the wheel hub is obtained from the real-time information of the wheel hub processing, the thermal imaging information is analyzed, the current temperature information of each area of ​​the wheel hub is obtained, and the continuous temperature information of each area is determined therefrom, and the current temperature information and the continuous temperature information are combined to determine the current insulation information of each area, and then the standard temperature information and the standard insulation information of the current process are obtained from the wheel hub information, the current insulation information and the standard insulation information are analyzed to determine the insulation temperature difference, and the current temperature information and the standard temperature information are analyzed to determine the variable temperature difference. The two differences provide key data for the subsequent calculation of the two indexes, and provide a reference for the deformation cause and deformation type. The two indexes are determined by the two differences, and the abstract quantity of deformation is concretized into a digital indicator, making the deformation judgment more intuitive and scientific.

[0031] Through the above technical scheme, the temperature change curve of each area is constructed according to the current temperature information and the number of time nodes is determined. The standard temperature change curve of each area is determined according to the hub information, which provides a reference benchmark for the temperature difference. The hub material information is obtained from the hub information, and then the material sensitivity coefficient is obtained, so that the judgment of the hub deformation is more in line with the actual characteristics of the hub material, and the calculation of the formula is universal. Finally, the temperature change curve, the standard temperature change curve and the material sensitivity coefficient are combined and substituted into the formula for calculation to obtain the temperature change period deformation index of each area, and the deformation is quantitatively evaluated, which helps to more intuitively understand the possible deformation of the hub during the processing process, and is more scientific and accurate than the traditional empirical model.

[0032] Through the above technical scheme, firstly, the current insulation time and the current insulation temperature are determined according to the current insulation information, and then the standard insulation time and the standard insulation temperature are determined according to the standard insulation information, which provides a reference benchmark for the subsequent determination of the possibility of deformation and provides standard specifications for processing the wheel hub. The insulation temperature difference is determined according to the current insulation temperature and the standard insulation temperature, and the material sensitivity coefficient and time factor are considered at the same time. The deformation possibility during the insulation period is quantified into an index through a mathematical formula, and the influence of temperature, material and time is fully considered rather than a simple calculation, so that the evaluation of wheel hub deformation is more accurate and scientific.

[0033] Through the above technical scheme, the rigidity strength requirements of each area are obtained from the wheel hub information, and the deformation coefficient is determined using the rigidity strength requirements of each area. The wheel hub deformation index is calculated using a mathematical formula based on the deformation index during the temperature change period, the deformation index during the insulation period and the deformation coefficient. The formula fully considers the deformation coefficient determined according to the rigidity strength requirements of each area, and comprehensively considers the influence of multiple factors on the wheel hub deformation index to more comprehensively evaluate the wheel hub deformation.

[0034] Through the above technical scheme, the deformation degree is first determined according to the insulation period deformation index of each area, and then the hub deformation area can be determined according to the temperature change period deformation index, the insulation period deformation index and the deformation coefficient of each area. By analyzing the insulation period deformation index and the temperature change period deformation index of each area, combined with the hub deformation index and the deformation coefficient, the specific area where the hub is deformed and the degree of deformation can be accurately determined, and then the hub material characteristics and the hub structure are determined according to the hub information, which serves as the basis for subsequent judgment of the deformation cause and determination of the deformation type. The deformation cause and deformation type are determined according to the temperature difference of temperature change, the insulation temperature difference, the hub material characteristics, the hub structure and the hub deformation area. Based on the comprehensive analysis of multi-dimensional factors, the cause of the hub deformation can be accurately judged, and the deformation area, deformation degree, deformation cause and deformation type of the hub are integrated to form a comprehensive evaluation of the hub deformation condition, which provides a strong basis for subsequent maintenance, repair or replacement.

[0035] Through the above technical scheme, firstly, the degree levels are divided according to the deformation degree and the hub deformation index. The division of degree levels is helpful to more accurately evaluate the hub deformation and provide a scientific basis for subsequent decision-making. Then, according to the degree levels, the impact of the repair operation on the hub is judged. When it is judged that the repair operation will affect the properties of the hub, unnecessary repair operations can be avoided, which wastes a lot of resources. When the repair operation does not affect the properties of the hub, the subsequent processing adjustment factors are determined according to the pre-processing influencing factors, deformation type, subsequent processing steps and hub information. When it is determined that the repair operation will not affect the properties of the hub, the subsequent processing adjustment factors are determined by comprehensively considering multi-dimensional factors, ensuring that the adjustment factors have a scientific basis, ensuring that the repair operation that adjusts the subsequent processing adjustment factors is feasible, and can effectively repair the hub deformation.

[0036] Through the above technical scheme, the adjustment content is first determined according to the subsequent processing steps and the subsequent processing adjustment factors, and then the adjustment content is determined according to the adjustment content. Then, the repair process parameters are determined according to the subsequent processing steps, deformation conditions, and adjustment tools. This can ensure that the determined process parameters are accurate and efficient and can complete the repair. The repair process parameters are then used to determine the adjusted processing steps, and the adjusted processing steps are determined as the adjustment strategy. The entire scheme determines the adjusted processing steps by comprehensively considering multiple factors, making the entire processing flow clearer and easier to operate and execute.

[0041] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme 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.

[0042] 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.

[0043] The embodiments of the present application are further described in detail below in conjunction with the drawings in the specification.

[0044] The existing detection technology in wheel hub processing uses X-ray, ultrasonic and other technologies to detect deformation of the wheel hub after forming. However, the deformation of the wheel hub during the wheel hub processing process cannot be detected in time. The deformation detection is performed after the wheel hub has been formed. If there is deformation at this time, the repair cost is high or it cannot be repaired, resulting in a large waste of resources.

[0045] Based on this, the present application provides a deformation detection method and system for wheel hub processing, which obtains and analyzes the wheel hub processing information in real time, determines the wheel hub position information and the wheel hub information, so as to facilitate and quickly determine the current processing flow information, and then determines the pre-processing steps and subsequent processing steps of the wheel hub by analyzing the wheel hub position information and the wheel hub information, and helps to determine if the wheel hub is deformed, find the cause of the wheel hub deformation, analyze the real-time information of the wheel hub processing and the wheel hub information, and determine whether the wheel hub is deformed. When deformation occurs, the deformation condition of the wheel hub is first determined to ensure that the deformation of the wheel hub is fully understood, so as to provide a basis for subsequent processing, and then determine where the problem occurred during the pre-processing according to the wheel hub information and the pre-processing factors, and then determine the subsequent processing adjustment factors according to the pre-processing influencing factors, deformation conditions, subsequent processing steps and the wheel hub information. Finally, the adjustment strategy is formulated by combining the subsequent processing adjustment factors and the wheel hub information. This scheme can determine the deformation of the wheel hub in a timely manner, which is convenient for subsequent remedial operations. If it cannot be remedied, the economic cost of subsequent processing operations can be saved, thereby improving the efficiency of wheel hub processing.

[0046] Figure 1 A schematic diagram of an application scenario provided for the present application. During the wheel hub processing process, the method provided by the present application is applied to timely discover the wheel hub deformation problem and provide adjustment strategies to improve processing efficiency.

[0047] Specifically, the method provided in the present application is applied to any server, which communicates with the wheel hub processing system. The server obtains the real-time information of the wheel hub processing from the wheel hub processing system and analyzes it to determine the wheel hub position information and wheel hub information, based on which the pre-processing steps and subsequent processing steps of the wheel hub are obtained, and whether the wheel hub is deformed is determined from the real-time information of the wheel hub processing. When deformation occurs, the deformation condition is determined from the real-time information of the wheel hub processing, and the pre-processing influencing factors are determined according to the pre-processing steps and the wheel hub information. The subsequent processing adjustment factors are determined according to the pre-processing influencing factors, the deformation condition and the subsequent processing steps, and the adjustment strategy is formulated, and the strategy is sent to the wheel hub processing system, so that the wheel hub deformation can be detected in time during the wheel hub processing process and corresponding adjustments can be made to avoid waste of resources and improve the efficiency of wheel hub processing. The specific implementation method can refer to the following embodiments.

[0048] Figure 2 This is a flow chart of a deformation detection method for wheel hub processing provided in an embodiment of the present application. The method of this embodiment can be applied to the server in the above scenario. Figure 2 As shown, the method includes:

[0049] S201, obtaining real-time information of wheel hub processing, analyzing the real-time information of wheel hub processing, and determining wheel hub position information and wheel hub information.

[0050] The real-time information of wheel hub processing may be the latest relevant information about the wheel hub processing process, and may include thermal imaging information, wheel hub position information, wheel hub information, wheel hub processing site image information, etc. The wheel hub position information may be information that reveals where the wheel hub is currently located in the wheel hub processing site, and the wheel hub position information may be used to determine the current wheel hub processing process. The wheel hub information may be various types of standard wheel hub information, and the wheel hub information may include size information, weight information, and processing process information, and the wheel hub information is presented in text form.

[0051] Specifically, in the specific steps of existing wheel hub processing, deformation detection can often be achieved. However, in the transition process between steps, deformation caused by previous improper operation is easily ignored, resulting in deformation having occurred in the next step, but it is difficult to detect, and the deformation of the wheel hub may become more serious due to subsequent processing, losing its repair value, thereby wasting a lot of resources. In order to determine whether the wheel hub is deformed in the transition process between processing steps, it is necessary to obtain real-time wheel hub processing information and wheel hub information, supplemented by technical means and analysis means, so as to determine the deformation of the wheel hub. After obtaining the real-time wheel hub processing information, it is analyzed through natural language processing technology and computer vision technology to obtain the wheel hub information, and then the wheel hub position information is determined using object recognition technology.

[0052] S202, determining the pre-processing steps and the subsequent processing steps of the wheel hub according to the wheel hub position information and the wheel hub information.

[0053] The preceding processing step may be a processing step preceding the current step to which the current wheel hub belongs in the entire processing flow. The subsequent processing step may be a processing step following the current step to which the current wheel hub belongs in the entire processing flow.

[0054] Specifically, the wheel hub processing process information can be obtained from the wheel hub information. According to the wheel hub position information, the image information in the wheel hub position information is identified through computer vision technology to determine the current position of the wheel hub and thus determine the step of the current wheel hub processing process in the entire processing process. The pre-processing steps and subsequent processing steps are determined based on the wheel hub processing process information. When the wheel hub is deformed, the pre-processing steps can provide necessary information for determining the cause of the deformation, and a wheel hub repair plan can be formulated based on the subsequent processing steps. The combination of the two makes the wheel hub repair work more scientific and efficient.

[0055] S203, analyzing the real-time information of wheel hub processing and the wheel hub information to determine whether the wheel hub is deformed.

[0056] Specifically, natural language processing technology is used to obtain processing parameters from real-time information of wheel hub processing, and at the same time, processing parameters required in the standard processing flow (hereinafter referred to as standard processing parameters) are obtained from the wheel hub information. The standard processing parameters of the wheel hub are the core basis for judging the deformation of the wheel hub, and mathematical analysis is used to determine whether deformation has occurred.

[0057] S204: If the wheel hub is deformed, determine the deformation status of the wheel hub according to the real-time processing information of the wheel hub, analyze the wheel hub information and the pre-processing steps, and determine the pre-processing influencing factors.

[0058] The deformation condition may be the deformation condition of the wheel hub, and the deformation condition may include deformation area, deformation degree, deformation cause, deformation type, etc. The pre-processing influencing factor may be the cause of the current deformation of the wheel hub in the pre-processing step when the wheel hub is deformed.

[0059] Specifically, due to the different functions of various areas of the wheel hub, there are also differences in the tolerance for wheel hub deformation. Therefore, when studying the deformation of the wheel hub, we cannot only focus on the overall situation and ignore the local situation. If we only focus on the overall situation, slight deformation occurs in some important areas (such as the rim), which is even lighter than the overall situation. However, because these areas bear the main work of the wheel hub, slight deformation can easily lead to a decrease in wheel hub performance, and then cause safety accidents. When the wheel hub is deformed, computer vision technology is used to divide the wheel hub area, and then the parameters of the processing process are obtained from the real-time information of the wheel hub processing. Through mathematical analysis, the deformation area, degree of deformation, cause of deformation, and type of deformation can be determined. These factors are determined as deformation conditions, and then the processing flow in the wheel hub information is used to determine where the problem is in the pre-processing.

[0060] S205, determining subsequent processing adjustment factors according to the pre-processing influencing factors, deformation conditions, subsequent processing steps and wheel hub information.

[0061] The subsequent processing adjustment factor may be that when the wheel hub is deformed, the subsequent processing steps need to be adjusted to repair the wheel hub, and the content that needs to be adjusted is the subsequent processing adjustment factor.

[0062] Specifically, in order to adjust the wheel hub in subsequent processing, it is necessary to determine the cause of deformation from the factors affecting the previous processing and determine the deformation condition. When the wheel hub is deformed, the natural language processing technology is used to obtain from the wheel hub information what the standard wheel hub that has not been deformed should look like, and then determine the cause of the deformation and what kind of deformation it has caused based on the previous processing factors, and then determine how the subsequent processing should be adjusted.

[0063] S206, combining subsequent processing adjustment factors with wheel hub information, formulating an adjustment strategy and sending it to the wheel hub processing system.

[0064] The adjustment strategy may be a strategy for adjusting subsequent processing steps in order to repair the deformed wheel hub.

[0065] Specifically, what needs to be adjusted is determined from the subsequent processing adjustment factors, so as to determine the adjustment strategy, and send it to the wheel hub processing system through computer communication technology.

[0066] Through the method provided in this embodiment, the real-time information of the hub processing is first obtained and analyzed, and the hub position information and the hub information are determined, which is convenient for the subsequent determination of the current hub processing process and the judgment of the hub deformation. The pre-processing steps and subsequent processing steps of the hub are determined according to the hub position information and the hub information, which provides key information for finding the cause when the hub is deformed. When the hub is deformed, the deformation condition of the hub is determined according to the real-time information of the hub processing, and the pre-processing influencing factors are determined according to the pre-processing steps, and which process in the pre-processing has a problem is more specifically determined. The subsequent processing adjustment factors are determined according to the pre-processing factors, deformation condition, subsequent processing steps and hub information. Through comprehensive analysis of multiple factors, scientific and accurate subsequent processing adjustments are determined, which provides an accurate processing method for the adjustment of the hub, and a strategy is formulated and sent to the hub processing system based on the subsequent processing adjustment factors and the hub information, providing strong decision-making support for the hub processing process.

[0067] In some embodiments, based on the real-time information of wheel hub processing, an image of the wheel hub processing site is determined; based on the wheel hub information, the wheel hub processing flow is determined; the image of the wheel hub processing site is analyzed to determine whether there is a processing device on site; if there is no processing device, the usage information of each device is obtained based on the real-time information of wheel hub processing; the usage information is analyzed to determine the most recently used device; based on the most recently used device and the wheel hub processing flow, the pre-processing steps and subsequent processing steps of the wheel hub are determined; if there is a processing device, the pre-processing steps and subsequent processing steps of the wheel hub are determined based on the processing device and the wheel hub processing flow.

[0068] The wheel hub processing site image may be a site image obtained by various monitoring devices in the current wheel hub processing process. The processing process may be the entire process of the steps that need to be performed in sequence in the current standardized production of the wheel hub. The processing device may be a device that is required to process the wheel hub in the steps of the processing process. The usage information may be information about the usage of the processing device, and the usage information may include usage time information, etc. The most recently used device may be a device in the processing device whose usage time is closest to the current time.

[0069] Specifically, in order to determine the pre-processing steps and subsequent processing steps of the current wheel hub, it is necessary to determine which processing devices are involved in the current process. The process can be directly determined from the processing device, and then the pre-processing steps and subsequent processing steps are determined in combination with the standard processing process. The wheel hub processing site image is obtained from the real-time information of the wheel hub processing, and the processing process in the wheel hub information is identified by natural language processing technology. Then, the object recognition technology in computer vision technology is used to determine whether there is a wheel hub processing device in the site image. If not, it is necessary to obtain the usage information of the processing device from the real-time information of the wheel hub processing, and the usage time is extracted from the usage information to obtain the device with the usage time closest to the current time, that is, the most recently used device, which represents the device used in the pre-processing step to determine the pre-processing step. Through the most recently used device, it is determined which step in the processing process needs to use the device, thereby obtaining the pre-processing step and subsequent processing step; when the site image contains a processing device, the current process of the wheel hub processing is determined through the processing device of the wheel hub processing process, thereby determining the pre-processing step and subsequent processing step.

[0070] Through the method provided in this embodiment, the wheel hub processing site image is first obtained from the wheel hub processing real-time information, and then the wheel hub processing flow is obtained from the wheel hub information. The determination of the wheel hub processing flow can know the standardized process, which helps to judge the pre-processing and subsequent processing, and determine whether there is a processing device on site from the site image. If not, it is necessary to determine the usage information of each device from the wheel hub processing real-time information, and then determine the most recently used device from the usage information, and then determine the pre-processing steps and subsequent processing steps of the wheel hub. When there is a processing device in the site image, the potential processing steps and subsequent processing steps of the wheel hub are determined through the processing device and the wheel hub processing flow. Regardless of whether the image information contains the information we want to know, the pre-processing steps and subsequent processing steps can be determined.

[0071] In some embodiments, thermal imaging information of the wheel hub is obtained based on real-time information of wheel hub processing; the thermal imaging information is analyzed to determine the current temperature information of each area of ​​the wheel hub; the current temperature information is analyzed to determine the continuous temperature information of each area; the current insulation information of each area is determined based on the current temperature information and the continuous temperature information; the wheel hub information is analyzed to determine the standard temperature information and standard insulation information of the current wheel hub processing process; the current insulation information and the standard insulation information are analyzed to determine the insulation temperature difference of each area; the current temperature information and the standard temperature information are analyzed to determine the variable temperature difference of each area; based on the variable temperature difference, the deformation index of each area during the variable temperature period is determined; based on the insulation temperature difference, the deformation index of each area during the insulation period is determined; the deformation index of the variable temperature period and the deformation index of the insulation period are analyzed to determine whether the wheel hub is deformed.

[0072] The thermal imaging information may be the thermal imaging information of the currently processed wheel hub. The current temperature information may be the temperature information obtained through the thermal imaging information of the wheel hub. The continuous temperature information may be the temperature information of the currently processed wheel hub changing with time. The current heat preservation information may be the temperature information of the currently processed wheel hub when the heat preservation operation is involved. The standard temperature information may be the standard temperature interval in the standard processing flow of the wheel hub. The standard heat preservation information may be the standard heat preservation temperature interval for heat preservation in the standard processing flow of the wheel hub. The heat preservation temperature difference may be the difference between the heat preservation temperature of the current wheel hub heat preservation period and the heat preservation temperature of the wheel hub heat preservation period in the standard processing flow, and the heat preservation period is the time period in the wheel hub processing flow for keeping the wheel hub temperature within a range. The temperature change temperature difference may be the difference between the temperature of the current wheel hub in the temperature change period and the temperature of the wheel hub in the standard processing flow in the temperature change period, and the temperature change period is the time period in the wheel hub processing flow for heating (cooling) from one temperature to another temperature. The temperature change period deformation index may be an index used to describe the possibility of deformation of the wheel hub in the temperature change period. The holding period deformation index may be an index used to describe the possibility of deformation of the wheel hub during the holding period.

[0073] Specifically, in order to obtain the hub deformation index, it is necessary to obtain the deformation index of the insulation period and the temperature change period. Since the processing operations in the insulation period and the temperature change period are different, the influence on the hub deformation is also different. Different means are needed to respectively obtain the deformation index of the insulation period and the deformation index of the temperature change period, and obtain the thermal imaging information of the hub from the real-time information of the hub processing. The thermal imaging information is analyzed by computer vision technology to divide the hub area, and then the current temperature information is obtained from it by natural language processing technology. Then, the time information is obtained from the temperature information, and the continuous temperature information of each area is determined in combination with the temperature information and the time information. The current insulation information of each area is determined according to the time information and the temperature information of the continuous temperature information. The standard temperature information and standard insulation information of the current hub processing process are extracted from the hub information by natural language processing technology. Through simple mathematical judgment, it is determined whether the current insulation temperature is within the range of the standard insulation temperature. When the current insulation temperature is within the range of the standard insulation temperature, the insulation temperature difference is 0.

[0074] When the current insulation temperature is not within the range of the standard insulation temperature, first determine whether the insulation temperature is greater than or less than the standard insulation temperature based on the current insulation temperature. When it is greater, use the upper limit of the standard insulation temperature for mathematical subtraction calculation. When it is less than, use the lower limit of the standard insulation temperature for mathematical subtraction calculation. For example, when the standard insulation temperature is 500℃ to 550℃ and the current insulation temperature is 490℃, then 500℃ minus 490℃, the insulation difference is 10℃. If the current insulation temperature is 570℃, then 570℃ minus 550℃, the insulation difference is 20℃. When in the temperature change period, the temperature has a process of change. According to the temperature information of this temperature change process and the temperature information of the standard temperature, a subtraction calculation similar to the insulation temperature difference is performed, but the difference is that the temperature difference of the temperature change is linked to time, and there is a difference in each unit time. For example, the standard temperature change process is 300℃ to 500℃, and it rises by 10℃ every second. The current temperature is 300℃, and it rises by 20℃ in the first second of the temperature change period. Then the temperature difference of the temperature change in the first second is 320℃-310℃, and the result is 10℃. According to the insulation temperature difference and the temperature change temperature difference of each area, the deformation index of each area in the temperature change period and the insulation period is determined, that is, the deformation index of the temperature change period and the deformation index of the insulation period, and then the deformation is judged by mathematical analysis.

[0075] Through the method provided in this embodiment, the thermal imaging information of the wheel hub is obtained from the real-time information of the wheel hub processing, which provides an information source for the subsequent acquisition of temperature information of each area, analyzes the thermal imaging information, obtains the current temperature information of each area of ​​the wheel hub, and determines the continuous temperature information of each area therefrom, combines the current temperature information with the continuous temperature information, determines the current insulation information of each area, and provides basic information for subsequent mathematical calculations, and then obtains the standard temperature information and standard insulation information of the current process from the wheel hub information, which provides a comparison standard for the subsequent determination of temperature differences, analyzes the current insulation information and the standard insulation information to determine the insulation temperature difference, and analyzes the current temperature information and the standard temperature information to determine the variable temperature temperature difference. The two differences provide key data for the subsequent calculation of two indexes and provide a certain reference for the deformation cause and deformation type. The two indexes are determined by the two differences, and the abstract quantity of deformation is concretized into a digital indicator, making the deformation judgment simpler, more intuitive and scientific.

[0076] In some embodiments, the temperature change curve and the number of time nodes of each region are determined according to the current temperature information; the standard temperature change curve and the hub material information of each region are determined according to the hub information; the material sensitivity coefficient is determined according to the hub material information; the temperature change curve of each region, the standard temperature change curve of each region and the material sensitivity coefficient are analyzed to determine the temperature change period deformation index of each region, referring to formula (1):

[0077] (1)

[0078] in, Indicates the deformation index of the current area during the temperature change period. Indicates the temperature change curve of the current area. The temperature at a time point, Indicates the standard temperature change curve of the current area. The temperature at a time point, Indicates the number of time nodes, Represents the material sensitivity coefficient.

[0079] The temperature change curve may be a curve showing the temperature of the currently processed hub changing with time when the hub is not in the heat preservation period. The number of time nodes may be the number of unit times in the temperature change curve of the currently processed hub when the hub is not in the heat preservation period. For example, if the unit time is 1s and the temperature change time is 20s, then the number of time nodes is 20. The standard temperature change curve may be a curve showing the temperature changing with time during the standard hub processing process. Hub material information may be information about the material used to manufacture the hub. Material sensitivity information may be information about the probability of hub material deformation due to inappropriate temperature.

[0080] Specifically, according to the current temperature information, use mathematical graphics drawing software, such as MATLAB, to draw a temperature change curve and determine the number of time nodes. According to the standard temperature information in the wheel hub information, also use mathematical graphics drawing software to draw a standard temperature change curve, and determine the material information of the wheel hub from the wheel hub information, and then determine the material sensitivity coefficient from the material information. The material sensitivity coefficient is related to the material itself and can be obtained based on historical conditions. According to the temperature change curve and the standard temperature change curve, determine the temperature difference value of each time node. In order to determine the temperature impact of the entire temperature change period, the temperature difference values ​​are accumulated as the temperature impact of the entire period. Considering the time factor, the accumulated temperature difference value is divided by the number of time nodes, and the obtained value is used as the temperature impact value. After the temperature impact value is obtained, consider the sensitivity of each material to temperature and multiply it by the material sensitivity coefficient. , and finally the deformation index during the temperature change period is obtained.

[0081] Through the method provided in this embodiment, the temperature change curve of each area is constructed according to the current temperature information and the number of time nodes is determined, so that the monitoring of the temperature change of the wheel hub is more detailed and comprehensive, and the standard temperature change curve of each area is determined according to the wheel hub information, and the wheel hub material information is obtained from the wheel hub information, and then the material sensitivity coefficient is obtained, so that the formula has universal applicability. Finally, the temperature change curve, the standard temperature change curve and the material sensitivity coefficient are combined and calculated through mathematical formulas to obtain the deformation index of each area during the temperature change period, so as to more intuitively quantify the possible deformation of the wheel hub during the processing process.

[0082] In some embodiments, the current insulation time and the current insulation temperature are determined according to the current insulation information; the standard insulation time and the standard insulation temperature are determined according to the standard insulation information; the insulation temperature difference of each area is determined according to the current insulation temperature and the standard insulation temperature; the insulation period deformation index of each area is determined according to the insulation temperature difference of each area, the current insulation time and the standard insulation time, referring to formula (2):

[0083] (2)

[0084] in, Indicates the deformation index of the current area during the insulation period. Indicates the current insulation temperature. Indicates the standard holding temperature, represents the material sensitivity coefficient, Indicates the preset adjustment coefficient, Indicates the current insulation time. Indicates standard holding time.

[0085] The current insulation time may be the time during which the wheel hub is subjected to insulation treatment during the current wheel hub processing. The current insulation temperature may be the temperature during which the wheel hub is subjected to insulation treatment during the current wheel hub processing. The standard insulation time may be the time during which the wheel hub is subjected to insulation treatment during the standard production process of the wheel hub. The standard insulation temperature may be the temperature during which the wheel hub is subjected to insulation treatment during the standard production process of the wheel hub.

[0086] Specifically, the current insulation time and the current insulation temperature are determined from the current insulation information, the standard insulation time and the standard insulation temperature are determined from the standard insulation information, and the insulation temperature difference is determined. When the insulation time exceeds the standard insulation time, the temperature will cause changes in the material structure, the internal stress of the hub, etc. These changes will cause the probability of deformation of the hub to increase. Therefore, the effect of time on deformation is not linear, and an exponential function is used. To describe this nonlinear relationship, since the deformation probability and the holding time are not a simple exponential relationship, a preset adjustment coefficient is introduced. Adjustments can be made. For example, if the standard insulation time is 5 minutes, and the actual insulation time is 6 minutes, the deformation probability may be 10%. When the actual insulation time is 7 minutes, the deformation probability is not 20%, but may be 30%.

[0087] Through the method provided in this embodiment, the current insulation time and the current insulation temperature are first determined according to the current insulation information, and then the standard insulation time and the standard insulation temperature are determined according to the standard insulation information, which provides a reference benchmark for the subsequent determination of the deformation possibility. At the same time, the material sensitivity coefficient and the time factor are considered, and the deformation possibility during the insulation period is quantified into an index through a mathematical formula, and the influence of temperature, material, and time is fully considered rather than a simple calculation, so that the evaluation of wheel hub deformation is more accurate and scientific.

[0088] In some embodiments, according to the wheel hub information, the rigidity strength requirements of each region are determined; according to the rigidity strength requirements of each region, the deformation coefficient is determined; according to the deformation index during the temperature change period, the deformation index during the heat preservation period and the deformation coefficient, the wheel hub deformation index is determined with reference to the following formula (3):

[0089] (3)

[0090] in, Represents the hub deformation index, Indicates The deformation index of the region during the insulation period, Indicates The deformation index of the regional temperature change period, Indicates The deformation coefficient of each area; according to the hub deformation index, determine whether the hub has deformed.

[0091] The rigidity strength requirement of each region may be the rigidity strength requirement of each region of the hub, and each region may include the rim, spokes, center hole, etc. The deformation coefficient may be a coefficient reflecting the influence of each region on the hub deformation. The hub deformation index may be an index reflecting the probability of hub deformation, and this deformation includes deformation during the temperature change period and deformation during the heat preservation period.

[0092] Specifically, the hub production standard is obtained from the hub information, and the strength requirements of each area of ​​the hub are obtained from the production standard. The deformation coefficient is determined according to the rigid strength requirements of each area. For example, the hub has a rim, a spoke, and other parts. Because the spoke is mainly used for decoration, the rigid strength requirement is relatively low, and the deformation coefficient is 1, but the rigid strength requirement of the rim is high, and the deformation coefficient is 10. If the insulation time is not appropriate, it will cause the hub material structure to change, the stress release is uneven, and other conditions will cause deformation. In the temperature change period, the inappropriate temperature change will cause the hub shape to change, the stress release is insufficient, and other conditions. Therefore, the hub may deform during both the insulation period and the temperature change period. The deformation probability during the temperature change period will be retained in the insulation period (the deformation probability during the insulation period will also be retained in the temperature change period). The two are not independent of each other. Therefore, it is necessary to calculate the hub deformation index according to the previously obtained temperature change deformation index and the insulation deformation index through formula (3), and set the deformation threshold according to historical experience. When the hub deformation index is greater than the deformation threshold, the hub is considered to be deformed.

[0093] Through the method provided in this embodiment, the rigidity strength requirements of each area are obtained from the wheel hub information, and the deformation coefficient is determined using the rigidity strength requirements of each area. The wheel hub deformation index is calculated using a mathematical formula based on the deformation index during the temperature change period, the deformation index during the insulation period, and the deformation coefficient. The formula fully considers the deformation coefficient determined according to the rigidity strength requirements of each area, and comprehensively considers the influence of multiple factors on the wheel hub deformation index to more comprehensively evaluate the wheel hub deformation.

[0094] In some embodiments, the deformation area and deformation degree of the hub are determined according to the deformation index of each area during the insulation period, the deformation index of each area during the variable temperature period, the hub deformation index and the deformation coefficient; the hub material characteristics and the hub structure are determined according to the hub information; the deformation cause and deformation type are determined according to the variable temperature difference, the insulation temperature difference, the hub material characteristics, the hub structure and the hub deformation area; the hub deformation area, deformation degree, deformation cause and deformation type are determined as the deformation condition of the hub.

[0095] The degree of deformation may be a quantity describing the magnitude of deformation determined based on the deformation index during the heat preservation period and the deformation index during the temperature change period. The hub material properties may be properties describing the physical and chemical properties of the hub material, and the hub material properties may include thermal expansion coefficient, elastic modulus, etc. The hub structure may be the shape and connection conditions of each area of ​​the hub. The cause of deformation may be the cause of deformation when the hub is deformed. The deformation type may be the type of deformation that occurs in the hub, and the deformation type may include shrinkage, cracking, etc. The deformation condition may be information describing all deformation conditions determined by combining multiple factors such as deformation area, deformation degree, deformation cause, and deformation type.

[0096] Specifically, the deformation degree is determined according to the size of the hub deformation index. The deformation index of each region during the insulation period is added to the deformation index of the temperature change period, and multiplied by the deformation coefficient to obtain the deformation index of each region. The regions are sorted by size, and the region identified as deformed is selected and used as the deformation region. For example, when the deformation index of a region is greater than 50, deformation has occurred. All indexes greater than 50 are selected and the region is determined. The period in which the deformation occurred is determined based on the temperature difference between the temperature change period and the temperature difference between the insulation period. The period in which the deformation occurred during the processing is determined based on the material properties and the hub structure. The cause of the deformation is determined based on the temperature information during this period. For example, when the temperature difference between the temperature change period is large, it is because the temperature control problem during the heat treatment leads to stress release problems and cracking. Finally, the place where the deformation occurred is determined based on the region. In order to comprehensively describe the deformation of the wheel hub and provide a reference for subsequent steps, a parameter is needed to generally reflect the deformation of the wheel hub. Considering that the repair step requires knowing which areas to repair and the type of deformation, it is necessary to understand the cause and degree of deformation when formulating a repair strategy. The deformation area, degree of deformation, cause of deformation, and type of deformation of the wheel hub are combined together as the deformation condition of the wheel hub to provide a reference for adjustments to subsequent processing steps.

[0097] Through the method provided in this embodiment, the deformation degree is first determined according to the insulation period deformation index of each area, and then the hub deformation area can be determined according to the temperature change period deformation index, the insulation period deformation index and the deformation coefficient of each area. By analyzing the insulation period deformation index and the temperature change period deformation index of each area, combined with the hub deformation index and the deformation coefficient, the specific area where the hub is deformed and the degree of deformation can be accurately determined, and then the hub material characteristics and the hub structure are determined according to the hub information. According to the above information, the deformation cause and deformation type are determined. Based on the comprehensive analysis of multi-dimensional factors, the cause of the hub deformation can be accurately judged to form a comprehensive assessment of the hub deformation condition.

[0098] In some embodiments, the degree of deformation and the hub deformation index are divided into degree levels; based on the degree levels, it is determined whether the repair operation affects the properties of the hub; if the repair operation does not affect the properties of the hub, the subsequent processing adjustment factors are determined based on the previous processing influencing factors, deformation type, subsequent processing steps and hub information.

[0099] The degree level may be information describing the degree of deformation of the hub. The hub property may be the mechanical property that the hub should have under normal circumstances.

[0100] Specifically, the degree level is divided according to the deformation degree and the size of the hub deformation index. For example, a hub deformation index greater than 100 and less than 300 is a slight deformation, greater than 300 and less than 500 is a moderate deformation, and greater than 500 is a severe deformation. After the degree level is divided, it is judged whether the repair operation will affect the properties of the hub according to the degree level. For example, when the degree level is a slight deformation, it is determined that the hub property will not be affected after the repair. When the degree level is a severe deformation, it is determined that it cannot be repaired. When the degree level is a moderate deformation, it needs to be judged specifically according to the hub area. When the repair operation does not affect the hub property, in order to save resource costs, the hub is directly repaired. The non-compliant parts in the pre-processing are determined from the pre-processing influencing factors, and then the subsequent processing adjustment factors are determined according to the deformation type, subsequent processing steps and hub information. For example, due to the residual material in the casting process, some parts of the hub protrude. According to the hub information, it is determined that the protruding parts are normal. Because there is a protrusion, the protruding part can be polished off in the subsequent processing, and the milling machine used for subsequent adjustment is used as an adjustment factor.

[0101] Through the method provided in this embodiment, the degree levels are first divided according to the deformation degree and the hub deformation index. The division of degree levels is helpful to more accurately evaluate the hub deformation situation. Then, according to the degree levels, the impact of the repair operation on the hub is judged. When it is judged that the repair operation will affect the properties of the hub, unnecessary repair operations are avoided. When the repair operation does not affect the properties of the hub, the subsequent processing adjustment factors are determined according to the previous processing influencing factors, deformation type, subsequent processing steps and hub information. When it is determined that the repair operation will not affect the properties of the hub, the subsequent processing adjustment factors are determined by comprehensively considering multi-dimensional factors to ensure that the adjustment factors have a scientific basis and that the repair operation that adjusts the subsequent processing adjustment factors is feasible.

[0102] In some embodiments, the adjustment content is determined according to the subsequent processing steps and the subsequent processing adjustment factors; the adjustment tool is determined according to the adjustment content; the repair process parameters are determined according to the subsequent processing steps, the deformation condition and the adjustment tool; the post-adjustment processing steps are determined according to the subsequent processing adjustment factors, the adjustment tool, the repair process parameters and the subsequent processing steps; and the post-adjustment processing steps are determined as the adjustment strategy.

[0103] The adjustment content may be all the content that needs to be adjusted in the subsequent processing for repair, and the adjustment content may include the processing sequence, processing equipment, etc. The adjustment tool may be a tool that can be used for repair operation among the tools used for processing in the subsequent processing steps, but some adjustments are required for repair. The repair process parameters may be the process parameters that need to be determined by the adjustment tool in order to repair the wheel hub.

[0104] Specifically, the operation of the step is determined from the subsequent processing steps, and then the content that needs to be adjusted is determined from the subsequent processing adjustment factors. When the specific adjustment content is known, the adjustment tool is determined by analyzing the content. For example, if the content that needs to be adjusted is the processing sequence, the tool used in the sequence that needs to be adjusted is used as the adjustment tool. The original process parameters obtained from the subsequent processing steps are used as a reference. According to the information of the deformation condition and the adjustment tool, the deformation type and deformation area are obtained from the deformation condition to determine the repair process parameters of the tool. For example, if the deformation type is that there is a partial protrusion and the deformation area is a spoke, then the repair tool is a milling cutter, and when the original milling position is not in the protruding part, an additional milling position needs to be added, and the milling speed, time and other parameters are determined. After determining the repair process parameters, the subsequent processing steps are adjusted to obtain the adjusted processing steps, and the adjusted processing steps are determined as the adjustment strategy.

[0105] Through the method provided in this embodiment, the adjustment content is first determined according to the subsequent processing steps and the subsequent processing adjustment factors, which can ensure that the direction and focus of the adjustment can meet the actual needs. Then, the adjustment content is determined according to the adjustment content. According to the subsequent processing steps, deformation conditions, and adjustment tools, the repair process parameters are determined to improve the accuracy of the process parameters. The repair process parameters are then used to determine the adjusted processing steps, and the adjusted processing steps are determined as the adjustment strategy. The adjusted processing steps are determined by comprehensively considering multiple factors, making the entire processing flow clearer and easier to operate and execute.
