[0043] Figure 2 It is a schematic diagram of the method flow of the present invention. DETAILED DESCRIPTION

[0044] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0045] like Figure 1 As shown, the flame straightening quality control system for cylindrical structural parts of the present invention includes a physical entity system, a virtual model system and a process optimization system.

[0046] The physical entity system includes cylindrical structural parts, orthopedic devices, straightness detection devices and visualization modules. The cylindrical structural parts are the cylindrical structural parts to be corrected. The orthopedic devices include orthopedic guns, orthopedic gas bottles and connecting pipes. The straightness detection device can detect the straightness of the cylindrical structural parts to be corrected before and after correction. The visualization module is the "5G+AR glasses+temperature sensor" visualization system. The physical entity system not only provides physical entity data for the process optimization system, but also makes timely adjustments to the correction process after receiving feedback information from the process optimization system, and uses the visualization module to guide the operator to correct the correction to ensure the correction quality.

[0047] The virtual model system includes a physical object model, an orthopedic mathematical model and a straightness prediction model. In the virtual model system, the cylindrical structural parts and the straightness detection device are digitally modeled to form a mapping relationship with the physical entity. Through real-time data, historical data and digital models, a mathematical model of orthopedic cylindrical structural parts is built. Through the mathematical model, orthopedic simulation analysis of cylindrical structural parts is carried out, and the relationship between the correction amount of cylindrical structural parts and the orthopedic temperature, orthopedic size, heating time, etc. is calculated to formulate a preliminary orthopedic process. According to the deformation amount and correction amount of the cylindrical structural parts before orthopedic surgery, the deformation amount of the cylindrical structural parts at different positions after orthopedic surgery can be known. The straightness prediction model is built using the least squares method, and the straightness of the cylindrical structural parts after orthopedic surgery in the virtual space is calculated. The straightness result is judged. If the straightness is qualified, the "5G+AR glasses" visualization device is used according to the formulated orthopedic process to guide the orthopedic surgery of the physical space cylindrical structural parts. If the straightness is unqualified, the orthopedic process is adjusted according to the information in the process optimization system knowledge base to output the optimal process parameters to guide the orthopedic surgery. Intelligent control and optimization of physical entities are achieved through the virtual model system.

[0048] The process optimization system includes a straightness detection module, a data query and analysis module, a knowledge base module, an orthopedic process optimization module, and an after-sales support module. The physical entity system and the virtual model system transmit raw material data, orthopedic process parameter data, detection data, and simulation analysis data to the process optimization system, and receive feedback from the process optimization system. The process optimization system realizes information interaction and data mapping between the orthopedic optimization of virtual cylinder-like structural parts and the orthopedic optimization of physical entity cylinder-like structural parts through data analysis.

[0049] The straightness detection module detects the straightness of cylindrical structural parts before and after correction, and realizes the centralized collection of raw material information, correction process information and straightness detection information, providing data support for straightness quality control. Raw material information includes raw material supplier manufacturer, whether the raw material is domestic / imported, raw material specification model, raw material processing method and raw material storage information. Correction scheme information includes cylindrical structural parts model, cylindrical structural parts size parameters, correction gas type, correction time, correction position, correction shape, correction points, correction size and operator information. Straightness detection information includes detection equipment information, detection process data and detection results. Raw material information, correction scheme information and straightness detection information are all saved in the database, which can be a commonly used database such as Excel and Access.

[0050] The data query and analysis module can query and analyze the orthopedic process data and the straightness data of cylindrical structural parts, and can query by inspection time, cylindrical structural part model or operator. A statistical process control chart can be established for the queried data to analyze whether the straightness data is normal and find abnormal point data in time.

[0051] The knowledge base module integrates the orthopedic process parameters of physical entity tubular structural parts, the orthopedic simulation analysis process parameters of virtual tubular structural parts and the relationship between the straightness of tubular structural parts. By recognizing and classifying data patterns and using statistical analysis methods to calculate and analyze data, it can provide knowledge and example support for the orthopedic simulation analysis of virtual model tubular structural parts and the orthopedic process of physical entity tubular structural parts, continuously optimize the orthopedic process, and improve the straightness accuracy of tubular structural parts. At the same time, real-time data also provides data support for the update of the knowledge base.

[0052] The orthopedic process optimization module is based on the simulation and straightness results of the orthopedic process of the virtual model tubular structural parts. It combines historical data and information in the knowledge base module to optimize the orthopedic process of the current tubular structural parts to be corrected. The temperature sensor is used to detect the orthopedic temperature in real time. The "5G+AR glasses" visualization device provides feedback to the orthopedic workstation to guide the correction, realize dynamic control of the correction, and ensure that the straightness of the tubular structural parts after correction meets the requirements.

[0053] The after-sales support module is associated with the product market maintenance information, builds a typical product failure database, analyzes the relationship between product failure modes and the orthopedic processing technology and straightness of cylindrical structural parts, and supports product after-sales service.

[0054] like Figure 2 As shown, the flame straightening quality control method of the cylindrical structural part of the present invention comprises the following steps:

[0055] Step (1) digitally modeling the cylindrical structural parts and the straightness detection device in the virtual model system to form a one-to-one mapping relationship with the physical entity.

[0056] Step (2) uses a straightness detection device to detect the straightness of the cylindrical structural part to be corrected, and uses an orthopedic mathematical model to simulate and analyze the correction process of the cylindrical structural part according to the position to be corrected and the amount of correction. By loading process parameters such as different correction sizes, heating times, and correction point positions, a simulation analysis of the correction of the cylindrical structural part is achieved.

[0057] The model of the correction amount, heating time and correction size of cylindrical structural parts is as follows:

[0058] △f=a0L 2 +a1T 2 +a2LT+a3L+a4T+a5+ε (1)

[0059] Among them, △f is the correction amount, L is the correction size, T is the heating time, a0, a1, a2, a3, a4, and a5 are regression coefficients. The regression coefficients can be obtained by performing regression analysis on historical data, and ε is the random error.

[0060] Step (3) uses the straightness prediction model to calculate the straightness of the tubular structural parts after the virtual space correction, and the side generatrix is ​​fitted according to the least squares method:

[0061] y = kx + b (2)

[0062]

[0063] where x i Indicates the distance between the correction position and any fixed end of the cylindrical structure, y i It indicates the deformation of the cylindrical structural component at the correction position after correction, and i indicates the number of correction points.

[0064] Calculate the radial distance from the point to the fitted line:

[0065] d=y i -kx i -b (4)

[0066] The difference between the maximum and minimum distances is the straightness of the cylindrical structure:

[0067] f=d max -d min (5)

[0068] Step (4) judges the straightness. If it meets the requirements, the correction process is fed back to the correction station using the "5G+AR glasses" visualization device to guide the correction. If it does not meet the requirements, the information in the knowledge base is retrieved and the correction process is re-planned according to the loop iteration.

[0069] Step (5) The orthopedic station performs orthopedic surgery according to the received optimal orthopedic process. After the orthopedic surgery is completed, a straightness detection module is used to perform a straightness detection.

[0070] After step (6) is completed, the test results, optimal orthopedic process parameters and other information are stored in the knowledge base module as historical data to guide the next quality control.
