Description

Technical Field

[0001] The present invention relates to the technical field of data processing, and in particular to a machining quality prediction system for key parts of an electro-hydraulic control actuator in the technical field of data processing. Background Art

[0002] In the design and manufacturing of electro-hydraulic actuators, the machining quality of key components determines their efficiency, response speed, and reliability. Therefore, quickly and accurately predicting the machining quality of key components is crucial. Machining quality prediction systems typically rely on manual operations and cumbersome processes, resulting in low production efficiency, severe information silos, and poor transferability. Therefore, it is crucial to design a machining quality prediction system that can efficiently and accurately predict the surface roughness of products at each step of boring, drilling, milling, and turning within the critical machining process data sheet for electro-hydraulic actuators.

[0003] The processing quality prediction of related technologies mainly relies on manual experience and simple statistical analysis methods. This method not only lacks scientificity and precision, but is also easily interfered with by subjective factors, such as operators' deviations in their understanding of process parameters, limitations of empirical judgment, and inconsistent standards among different personnel. These problems seriously affect the accuracy and reliability of processing quality predictions. At the same time, to improve prediction efficiency, some companies use simple mathematical models for batch predictions, substituting relevant data from the processing process into the model for calculation. However, these models are often established under specific conditions. If the actual processing scenario is complex and changeable, and the data contains noise or outliers, they will be directly applied without optimization and verification, resulting in large deviations in the prediction results. Summary of the Invention

[0004] The purpose of the present invention is to provide an intelligent anticipatory control method for extreme stability, and the technical solutions adopted are as follows:

[0005] An embodiment of the present invention provides a system for predicting the machining quality of key parts of an electro-hydraulic control actuator, the system comprising:

[0006] The data entry and display module is used to display the imported processing route data table of key parts of electro-hydraulic control actuators;

[0007] A user authority and security management module is used to establish login authority for the electro-hydraulic control actuator key parts processing quality prediction system to control user access rights to the system;

[0008] The processing quality prediction module is used to predict the surface roughness of the product of each step in the processing process route data table using the surface roughness prediction model corresponding to the system to obtain a prediction result.

[0009] In some possible implementations, the data entry and display module is used to display the process steps, corresponding process parameters, process numbers, process names and process parameters of the key parts in a corresponding table where the processing process route data table is located.

[0010] In some possible implementations, the key parts include at least a piston, a piston rod, a flange, a cylinder head, a cylinder body, and a rod barrel.

[0011] In some possible implementations, the process steps include at least: rough turning, semi-finishing turning, finishing turning, slot milling, finishing grinding, rough grinding, threaded hole drilling, and chrome plating.

[0012] In some possible implementations, the process parameters include: spindle speed, cutting speed, feed rate, and back cutting depth.

[0013] In some possible implementations, the data entry and display module includes: a visual operation interface;

[0014] The visual operation interface is used to receive the processing data information of the key parts of the electro-hydraulic control actuator imported by the user terminal; and allows the user terminal to browse the local file system, select the table file that stores the processing data information, read the content of the table file and store it in the grid virtual table.

[0015] In some possible implementations, the data entry and display module is also used to compile the processing route data table using a preset programming language and store it in a switch control; read the content in the network virtual table, and display the content in the network virtual table and the data stored in the switch control in a data grid view control.

[0016] In some possible implementations, the processing quality prediction module is also used to construct a processing quality prediction system for key parts of electro-hydraulic control actuators based on a multivariate linear regression mathematical model, and use the process parameters of each step of boring, drilling, milling and turning in the processing process route data table as input parameters to predict the surface roughness of the product of each step, obtain and output the corresponding position of the data entry and display module of the initial surface roughness, so as to calculate and display the comprehensive surface roughness, and use the comprehensive surface roughness as the prediction result.

[0017] In some possible implementations, the user authority and security management module is also used to manage the login authority of the user terminal and control the access rights of the user terminal; receive the authenticated and authorized user name and password credentials input by the user terminal through the identity authentication module, so that the user terminal can log in to the user registration interface of the electro-hydraulic control actuator key parts processing quality prediction system.

[0018] In some possible implementations, the access rights include: system login permission and password modification permission.

[0019] The present invention has the following beneficial effects: in the electro-hydraulic control actuator key parts processing quality prediction system, the imported electro-hydraulic control actuator key parts processing process route data table is displayed through the data entry and display module to improve the visualization of the data. The login authority of the electro-hydraulic control actuator key parts processing quality prediction system is established through the user authority and security management module to control the user end's access rights to the electro-hydraulic control actuator key parts processing quality prediction system; thereby ensuring the security of the prediction system. The surface roughness of the product of each step in the processing process route data table is predicted by the processing quality prediction module to obtain a prediction result; in this way, by deeply analyzing and mining the detailed parameters of the processing process data table, an accurate prediction of the processing quality is achieved, which can not only improve the accuracy of the prediction, but also avoid errors caused by subjective factors and model limitations.

In the following description, references to "one embodiment" or "another embodiment" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics of one or more embodiments may be combined in any suitable manner.

[0031] In the description of the embodiments of the present invention, unless otherwise specified, " / " means or, for example, A / B can mean A or B: "and / or" in the text 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 mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present invention, "multiple" refers to two or more than two.

[0032] In the following, the terms "first" and "second" are used for descriptive purposes only and should not be understood to imply or suggest relative importance or implicitly indicate the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0033] Unless otherwise defined, all technical and scientific terms used in the embodiments of the present invention have the same meanings as commonly understood by one of ordinary skill in the art to which the present invention belongs.

[0034] In related technologies, generalization and adaptability often become bottlenecks for the development of single prediction models when faced with diverse machining processes and complex production environments. Therefore, designing an efficient and accurate machining quality prediction solution has important practical significance and application value in assisting companies to adjust machining parameters and process flows in a timely manner.

[0035] Based on this, the embodiment of the present invention constructs an intelligent processing quality prediction system, which deeply analyzes and mines the detailed parameters of the processing technology data table by building a comprehensive and accurate surface roughness prediction model, thereby achieving accurate prediction of processing quality and avoiding errors caused by subjective factors and model limitations. Figure 1 As shown, the machining quality prediction system 11 for key parts of electro-hydraulic control actuators includes a data entry and display module 101, a machining quality prediction module 102, and a user authority and security management module 103. The data entry and display module 101 supports manual data entry and display. The machining quality prediction module 102 is used for surface roughness prediction and comprehensive surface roughness calculation. The user authority and security management module 103 supports user registration, system login, and password modification.

[0036] The following is a detailed description of the specific scheme of the electro-hydraulic control actuator key parts processing quality prediction system provided by the present invention in conjunction with the accompanying drawings. Figure 2 , which shows a schematic diagram of the implementation process of a system for predicting the machining quality of key parts of an electro-hydraulic control actuator provided by an embodiment of the present invention. The system 200 includes:

[0037] The data entry and display module 201 is used to display the imported processing process route data table of the key parts of the electro-hydraulic control actuator.

[0038] Here, the data entry and display module is used to display the process steps, corresponding process parameters, process number, process name and process parameters of the key parts in the corresponding table where the processing process route data table is located. Among them, the key parts include at least: piston, piston rod, flange, cylinder head, cylinder body and rod barrel. The process steps include at least: rough turning, semi-finishing turning, finishing turning, milling, fine grinding, rough grinding, drilling threaded holes, and chrome plating. The process parameters include: spindle speed, cutting speed, feed rate, and back cutting amount. The data entry and display module can support users to manually import the processing process route data table of key parts of electro-hydraulic control actuators and display it in the table to improve the visualization of the data. The processing process route data of key parts of electro-hydraulic control actuators is the input data of the processing quality prediction system. It is the basis for the functions of the data entry and display module and the processing quality prediction module to realize the functions of the data entry and display module and the processing quality prediction module. The processing process route data table of key parts of electro-hydraulic control actuators mainly consists of two parts, namely the process steps of the parts and their corresponding detailed parameters. Such as Figure 3As shown in the figure, the processing route data of the key parts of the electro-hydraulic control actuator include: key parts, main process steps and main process parameters (i.e. process parameters); among them, the key parts include: piston, piston rod, cylinder body, rod barrel and cylinder head; the main process steps include: turning, milling, drilling and boring pins; the main process parameters include: spindle speed, back cutting amount, feed rate and cutting speed.

[0039] The data entry and display module supports users to import the processing route data table of key parts of electro-hydraulic control actuators through manual input.

[0040] In some possible implementations, the data entry and display module includes: a visual operation interface;

[0041] The visual operation interface is used to receive the processing data information of the key parts of the electro-hydraulic control actuator imported by the user terminal; and allows the user terminal to browse the local file system, select the table file that stores the processing data information, use the NPOI library to read the content of the table file and store it in the grid virtual table.

[0042] Manually input processing data information in the visual operation interface. Based on the Visual Studio platform, a visual operation interface for importing data is designed. Users can manually import the processing data information of key parts of electro-hydraulic control actuators through this interface. The design of this visual operation interface requires establishing a connection channel between the local file system and the Visual Studio platform based on the C# programming language, allowing users to browse the local file system, select an Excel file that stores the processing data information of key parts of electro-hydraulic control actuators, and use the NPOI library to read the content of the selected file. The visual operation interface is as follows: Figure 4 As shown, the data entry interface 41 (i.e., visual operation interface) of the electro-hydraulic control actuator key parts processing quality prediction system includes multiple buttons, such as return, import EXCEL file, exit, etc.

[0043] The local file system is connected to the Visual Studio platform, allowing users to browse the local file system in the following format:

[0044] OpenFileDialog openFileDialog=new OpenFileDialog();

[0045] openFileDialog.Filter="Excel Files|*.xlsx";

[0046] openFileDialog.Title="Select an Excel File";

[0047] string filePath=openFileDialog.FileName;

[0048] Among them, "OpenFileDialog openFileDialog = new OpenFileDialog();" is to instantiate an object for opening a file selection dialog box, "openFileDialog.Filter = "Excel Files|*.xlsx";" means to limit the file types of the file selection dialog box to only display Excel files with the extension .xlsx, "openFileDialog.Title = "Select an Excel File";" means to set the title of the file selection dialog box to prompt the user to select an Excel file, and "string filePath = openFileDialog.FileName;" is to get the full path of the selected file.

[0049] Specifically, users can perform manual input operations according to the following process:

[0050] First, click the "Import Excel" button. The system will establish a connection channel between the local file system and the Visual Studio platform, and then display the file selection dialog box. After the user completes the selection of the Excel file in the local file system, the system will obtain the full path of the Excel file based on the user's selection. Finally, the system uses the NPOI library to read the contents of the selected Excel file.

[0051] Specifically, based on the C# programming language, you can use the NPOI library to read the contents of the selected Excel file as follows:

[0052] Table 1 Read the contents of the selected Excel file using the NPOI library

[0053]

[0054] In some possible implementations, the data entry and display module 201 is also used to compile the processing route data table using a preset programming language and store it in a switch control; read the content in the network virtual table, and display the content in the network virtual table and the data stored in the switch control in a data grid view control.

[0055] Here, the display process is a set of pre-compiled C# programming language statements, which are stored in the Button control and executed by the data import system. It can read the data in the DataTable and then display the specific data information in the DataGridView control.

[0056] The user authority and security management module 202 is used to establish login authority for the electro-hydraulic control actuator key parts processing quality prediction system to control the user's access authority to the system.

[0057] Here, the user authority and security management module is also used to manage the login authority of the user terminal and control the access rights of the user terminal; receive the authenticated and authorized user name and password credentials input by the user terminal through the identity authentication module, so that the user terminal can log in to the login interface of the electro-hydraulic control actuator key parts processing quality prediction system.

[0058] In some possible implementations, the user authority and security management module implements the management of user login authority and controls the user's access rights to the machining quality prediction system. Figure 5 As shown, the user name and password can be input in the login interface 51 of the electro-hydraulic control actuator key parts processing quality prediction system, and operations such as user registration, login, password modification and return can also be performed. Access rights include: system login permission and password modification permission. Unregistered users need to register by entering the user name and password, and in order to avoid errors when entering the password, the system requires the user to enter the password again for confirmation. After entering the user name and password and completing the password confirmation, the system login permission can be obtained. Then, the registered user can enter the user name and password credentials authenticated by the system through the identity authentication module and successfully log in to the human-computer interaction interface of the electro-hydraulic control actuator key parts processing quality prediction system. The user registration interface of the electro-hydraulic control actuator key parts processing quality prediction system is shown as follows: Figure 6 As shown, in the user registration interface 61 of the electro-hydraulic control actuator key parts processing quality prediction system, user name and password can be input, password confirmation can be performed, and user registration and return operations can also be performed.

[0059] For the user registration function, you can perform operations using the following C# programming language:

[0060] private string filePath="accounts.txt";

[0061] if(!File.Exists(filePath)){

[0062] File.Create(filePath).Close();}

[0063] string pattern=@"^(?=.*[az])(?=.*[AZ])(?=.*\d)

[0064] (?=.*[@$!%*?&])[A-Za-z\d@$! %*? &]{8,}$";

[0065] return Regex.IsMatch(password,pattern);

[0066] string username=usernameBT.Text.Trim();

[0067] string password=passwordBT.Text;

[0068] string confirmPassword=ConfirmpasswordBT.Text;

[0069] SaveAccountToFile(username,password);

[0070] Among them, accounts.txt is the file address that stores the user's registered account and password. In order to improve the security of the system, reduce the risk of data leakage and database collision, and enhance user security awareness, set the standard rules for the strength of the registered password: at least 8 characters, including uppercase letters, lowercase letters, numbers and special symbols.

[0071] At the same time, in order to further protect the security of the account, a password modification function is set to facilitate users to flexibly adjust according to their own circumstances. If the original password is forgotten or difficult to remember, it can be changed to something easy to remember for easy login. When the user changes the password, the system will first require the user to enter the current username and password for identity authentication. This is to ensure that only the real holder of the account can perform password modification operations to prevent malicious tampering by others. If the current password is entered incorrectly, the system will prompt the user to re-enter it to increase security. After the identity authentication is passed, the user enters the password modification page. The new password must meet the strength requirements of at least 8 characters in length and must contain uppercase letters, lowercase letters, numbers and special characters to help users set a secure password. In order to avoid errors when the user enters the new password, the system requires the user to enter the new password again for confirmation. The two passwords must be exactly the same, otherwise the system will prompt the user to re-enter. When the user completes the input and confirmation of the new password, click the Change Password button. The system will encrypt the new password and store it in the database to complete the password modification operation. The password modification interface of the key parts processing quality prediction system of electro-hydraulic control actuators is as follows Figure 7 As shown, in the password modification interface 71 of the electro-hydraulic control actuator key parts processing quality prediction system, user name, new password, old password, and confirmation password can be input, and user registration and return can also be performed.

[0072] For the authentication function in the password modification function, you can perform the operation through the following C# programming language:

[0073]

[0074] CheckLoginCredentials is a custom function that verifies whether the username and password entered by the user match the user information stored in the specified file.

[0075] For the password modification function, you can perform the operation through the following C# programming language:

[0076]

[0077] Among them, CheckOldCredentials and ChangePassword are both custom functions. The main function of the CheckOldCredentials function is to verify whether the username and old password entered by the user match the user information stored in the specified file. The function of the ChangePassword function is to change the password of the specified user: by reading the file storing user information, finding the record corresponding to the username and updating its password, and finally writing the updated information back to the file.

[0078] The processing quality prediction module 203 is used to predict the surface roughness of the product of each step in the processing process route data table using the surface roughness prediction model corresponding to the system to obtain a prediction result.

[0079] Here, the processing quality prediction module is also used to construct a processing quality prediction system for key parts of electro-hydraulic control actuators based on a multivariate linear regression mathematical model, and use the process parameters of each step of boring, drilling, milling and turning in the processing process route data table as input parameters to predict the surface roughness of the product of each step, obtain and output the corresponding position of the data entry and display module of the initial surface roughness, so as to calculate and display the comprehensive surface roughness, and use the comprehensive surface roughness as the prediction result.

[0080] In some possible implementations, the processing quality prediction module adopts a processing quality prediction system based on a multivariate linear regression mathematical model, and uses the specific processing parameters of each boring, drilling, milling and turning step in the imported electro-hydraulic control actuator key parts processing process route data as the model input parameters. The specific processing parameters include: spindle speed, cutting speed, feed rate and back cutting amount. The surface roughness is used to represent the processing quality. The surface roughness of the product of each boring, drilling, milling and turning step in the imported electro-hydraulic control actuator key parts processing process route data table is accurately predicted, and then the predicted surface roughness is output to the corresponding position of the display table, and the comprehensive surface roughness is calculated to improve the convenience of data visualization and display. The interface of the electro-hydraulic control actuator key parts processing quality prediction system is as follows: Figure 8 As shown, in the electro-hydraulic control actuator key parts processing quality prediction system interface 81, operations such as return, prediction, and exit can be performed, and the comprehensive surface roughness can also be displayed.

[0081] Since the surface roughness prediction mathematical models used in different process steps of different parts are different, an automatic recognition function is designed. It can accurately predict the processing quality by automatically identifying the part name and process step content and selecting the corresponding surface roughness prediction mathematical model saved in the system.

[0082] For the automatic recognition function, you can perform operations using the following C# programming language:

[0083]

[0084] Specifically, users can perform processing quality prediction operations according to the following process:

[0085] The user first needs to click the "Predict" button. The system will automatically read all the data in the imported processing route data table of the key parts of the electro-hydraulic control actuator, and automatically identify the part name and work step content. By judging the combination of different part names and different work step contents, the corresponding surface roughness prediction mathematical model saved in the system is selected. Then, the specific process parameters such as cutting speed, feed rate, back cutting amount and spindle speed of the work step are input into the surface roughness prediction mathematical model to accurately predict the surface roughness, and the specific surface roughness value is output to the corresponding position of the display table. Finally, the comprehensive surface roughness is calculated and displayed in the text box.

[0086] The comprehensive surface roughness is the average value of the product surface roughness for each boring, drilling, milling, and turning process step in the machining process data table for key parts of electro-hydraulic control actuators. The comprehensive surface roughness is calculated based on the need for front-line operators in the enterprise to promptly determine whether the cutting speed, feed rate, back-cut depth, and spindle speed in the part machining process are appropriate, and to promptly detect abnormal conditions during the machining process so that corresponding measures can be taken to make adjustments and ensure the stability of product quality.

[0087] Specifically, operations can be performed using the C# programming language:

The login authority of the electro-hydraulic control actuator key parts processing quality prediction system is established through the user authority and security management module to control the user end's access rights to the electro-hydraulic control actuator key parts processing quality prediction system; thereby ensuring the security of the prediction system. The surface roughness of the product of each step in the processing process route data table is predicted by the processing quality prediction module to obtain a prediction result; in this way, by deeply analyzing and mining the detailed parameters of the processing process data table, an accurate prediction of the processing quality is achieved, which can not only improve the accuracy of the prediction, but also avoid errors caused by subjective factors and model limitations.
