Technical Field

[0001] The present invention is a production and processing method for precision mechanical basic parts, belonging to the field of production of mechanical basic parts. Background Art

[0002] The processing of mechanical basic parts is one of the essential links in the whole life cycle of product R & D. The processing method and accuracy of mechanical basic parts largely determine the final quality of product R & D. Moreover, various machine tools are bound to be used in the process of product R & D. The use and scheduling of machine tools in the processing of mechanical basic parts affect the efficiency of product R & D to a certain extent. Therefore, the processing of mechanical basic parts plays a crucial role in the whole process of the workshop.

[0003] In the existing manufacturing and processing of mechanical basic parts, most are manual blanking and processing, resulting in low utilization rate of mechanical basic part templates, serious material waste, poor processing quality, high labor cost and low efficiency. The technical characteristics of processing lathe equipment are high automation, high processing accuracy, stable and reliable processing quality, and high production efficiency, which can improve working conditions, reduce manual operations, facilitate production management, and the application of CNC lathes in the industry has been relatively mature. Therefore, the present invention proposes to introduce it into the research of mechanical basic part processing technology and form a complete set of mechanical basic part automatic processing method. Summary of the Invention

[0004] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a production and processing method for precision mechanical basic parts.

[0005] In order to achieve the above purpose, the present invention is realized through the following technical solutions:

[0006] A production and processing method for precision mechanical basic parts, including a virtual production design model of mechanical basic parts, a processing machine tool, and a mechanical basic part template;

[0007] S101. Analyze the mechanical basic parts and conduct software modeling to obtain a virtual production design model of the mechanical basic parts to be processed, and simulate the processing process parameter values of the mechanical basic parts;

[0008] S102. Transmit the obtained processing process parameter values of the mechanical basic parts to the processing machine tool, and the processing machine tool performs numerical control processing on the pre-configured mechanical basic part template according to the processing process parameter values of the mechanical basic parts;

[0009] S103. Transport and store the processed mechanical basic part template through a conveyor.

[0010] In addition, when analyzing mechanical basic parts and performing software modeling to obtain the corresponding virtual production design module of mechanical basic parts, the virtual production design model of mechanical basic parts uses Siemens NX software to establish a virtual model of the processing module.

[0011] Among them, the simulation method of the processing process parameter values of mechanical basic parts includes the following steps:

[0012] Step 1: Integrate several processing process parameters of the mechanical basic part template into a process parameter array, such as A, B···F···;

[0013] Then divide each processing process parameter into several sub-values, such as A1, A2, A3···, B1, B2, B3···, ···, F1, F2, F3···;

[0014] Step 2: Extract a combination of sub-values of each processing process parameter to form a new process parameter array, and substitute it into the virtual production design model of mechanical basic parts to calculate the processing efficiency of the new process parameter array;

[0015] Step 3: Repeat the above Step 2 to obtain the processing efficiencies corresponding to several new process parameter arrays, and select the process parameter array corresponding to the most suitable processing efficiency as the processing process parameter value of the mechanical basic part template.

[0016] In addition, in the processing machine tool, the processing machine tool also includes a video monitoring module, an alarm module and a storage module:

[0017] The video monitoring module, when the processing personnel operate the processing machine tool, real-time collects the video data of the processing personnel during the processing of the mechanical basic part template, and performs behavior recognition analysis on the collected video data;

[0018] The video monitoring module sends the detected video data to the storage module for storage through the server, and performs behavior recognition analysis on the collected video data to identify whether there are any illegal operations by the corresponding processing personnel during the processing of the parts. When there are illegal operations, a violation signal is generated. After receiving the violation signal, the alarm module gives an alarm, playing a role in warning the processing personnel of safe operation.

[0019] In addition, during the transportation and storage of the processed mechanical basic part template, a training recognition-based product inspection is performed on the mechanical basic part template to detect unqualified parts;

[0020] And send the unqualified mechanical basic part template to the inspection center. The inspection center performs a second inspection on the parts with processing defects, and enters the detection results of the defective parts of the unqualified mechanical basic part template into the database.

[0021] Among them, product inspection includes the inspection of the surface flatness of the mechanical basic part template, the inspection of defects in the surface texture of the mechanical basic part template, and the inspection of contour deformation of the mechanical basic part template.

[0022] In addition, the training-based product inspection includes the following steps:

[0023] Step 1: Input the pictures of the processed complete parts into the Galileo convolutional neural network model for training, and extract the contour features and surface texture features of the complete parts.

[0024] Step 2: During transportation, install a camera on the conveyor used, take pictures of each surface of the mechanical basic part template during transportation, and transmit them to the trained Galileo convolutional neural network model to identify the mechanical basic part templates with defective contours, surface textures, and flatness.

[0025] In addition, number the mechanical basic part templates for the qualified products, and obtain the usage location information, processing usage method information, and installation method information of the mechanical basic part templates;

[0026] Based on the number, usage method information, and installation method information, generate a QR code and paste the QR code on the mechanical basic part template;

[0027] When subsequently classifying and storing the obtained mechanical basic part templates, use an automated robotic arm to store the obtained mechanical basic part templates.

[0028] Advantages of the present invention:

[0029] The present invention combines intelligent technology and automation technology. Through precise design, efficient processing, strict quality inspection, and intelligent management and optimization, it realizes the precision machining, low cost, and high quality of mechanical basic parts. Using an automated processing machine tool to process mechanical basic parts reduces the intervention of manual operations and improves processing efficiency.

[0030] Through the automated control system, precise positioning and processing of the processing machine tool are carried out, ensuring processing accuracy and quality. By using the processing machine tool of automated machinery to process mechanical basic parts, the labor cost and material waste can be significantly reduced, and the economic benefits can be improved.

[0031] And during specific processing, precise inspection is carried out on the machined mechanical basic parts to screen out unqualified processed products. The most effective processing efficiency is adopted, that is, the most effective processing process parameter values are used to machine parts to achieve the maximum processing efficiency. During processing, the video monitoring module monitors the manual operations and uploads them to the storage module. A large number of processing operation methods are stored in the storage module. When the worker's operation method is incorrect, a violation signal is generated. After receiving the violation signal, the alarm module gives an alarm to warn the processing personnel of safe operations, so as to improve strict quality processing, increase the qualified rate of products, and further improve the processing efficiency.

[0047] In addition, in the above alternative embodiment, the simulation method for the machining process parameter values of the mechanical basic parts includes the following steps:

[0048] Step 1: Integrate several machining process parameters of the mechanical basic part template into a process parameter array, such as A, B... F...;

[0051] Step 3: Repeat the above Step 2 to obtain the processing efficiencies corresponding to several new process parameter arrays, and select the process parameter array corresponding to the most suitable processing efficiency as the machining process parameter value of the mechanical basic part template.

[0052] In addition, in the above optional embodiment, in the machining tool, the machining tool further includes a video monitoring module, an alarm module, and a storage module:

[0053] The video monitoring module, when the machining personnel operate the machining tool, collects the video data of the machining personnel during the machining process of the mechanical basic part template in real time, and performs behavior recognition and analysis on the collected video data;

[0054] The video monitoring module sends the detected video data to the storage module for storage via the server, and performs behavior recognition and analysis on the collected video data to identify whether there are any illegal operations during the machining process of the corresponding machining personnel.

[0063] When the obtained mechanical basic part templates are subsequently classified and stored, an automated robotic arm is used to store the obtained mechanical basic part templates.

[0064] In order to better implement a precision mechanical basic part production and processing method of the present invention, the above conveyor can also be adjusted to better meet and implement the above technical solution steps of the embodiment, specifically as follows:

[0065] Refer to Figure 2-3 , the conveyor is divided into a first conveyor belt machine 1 and a second conveyor belt machine 2. A setting frame 3 is fixedly arranged on the frame of the first conveyor belt machine 1. A moving component is arranged on the setting frame 3. The moving component includes a driving motor 1 4. One end of the output shaft of the driving motor 1 4 is rotationally connected to a first lead screw 5 through a first bearing. A moving plate 6 is threadedly sleeved on the outer surface of the first lead screw 5. A traction chute 7 for the moving plate 6 to penetrate is opened on the setting frame 3. The processed mechanical basic part templates are transported through the first conveyor belt machine 1. Cameras are arranged at all positions on the first conveyor belt machine 1 to take photos. When it is detected that the product is unqualified, the driving motor 1 4 is controlled to start, driving the first lead screw 5 to rotate, thereby driving the moving plate 6 to move on the first lead screw 5, and finally driving the subsequent clamping component to move above the mechanical basic part template. Then, the subsequent clamping work of the mechanical basic part template is completed through the clamping component. The first conveyor 1 is a roller rod type conveyor.

[0066] Refer to Figure 2-3 , a setting table 8 is arranged at the bottom end of the moving plate 6. An electric telescopic rod is arranged inside the moving plate 6. The output end rod of the electric telescopic rod penetrates to the outside of the moving plate 6 and is fixedly arranged on the setting table 8. A clamping component is arranged on the setting table 8. The clamping component includes a driving motor 2 9. One end of the output shaft of the driving motor 2 9 is rotationally connected to a second lead screw 10 through a second bearing. The second lead screw 10 is a double-axis lead screw, and two clamping plates 11 are threadedly sleeved at both ends of the double-axis lead screw. A secondary traction chute 12 for the clamping plates 11 to penetrate is opened on the setting table 8. A bottom support component is also arranged on the moving plate 6. Then, the electric telescopic rod drives the setting table 8 to move downward, and finally drives the clamping component to move down to the mechanical basic part template. Then, the second lead screw 10 is started to drive the two clamping plates 11 to move relative to each other on the second lead screw 10, and finally cooperate with the clamping plates 11 to complete the clamping work of the mechanical basic part template. Then, the clamped mechanical basic part template is lifted.

[0067] Refer toFigure 3-6 , the bottom support assembly includes a fixed frame 13 fixed on the moving plate 6. A secondary electric telescopic rod 14 is arranged on the fixed frame 13. The output end of the secondary electric telescopic rod 14 is connected with a U-shaped pushing frame 15. A U-shaped seat 16 is fixedly arranged on the fixed frame 13. A rotating rod 17 is fixedly arranged inside the U-shaped seat 16. A bottom support plate 18 is movably sleeved on the rotating rod 17. A through rod 19 movably penetrates through the bottom support plate 18. Bearings III 20 are sleeved at both ends of the through rod 19. The bearings III 20 are fixed inside the U-shaped pushing frame 15. A sliding groove 21 for the through rod 19 to slide through is formed on the U-shaped seat 16. An activity groove 22 for the through rod 19 to penetrate through is formed on the bottom support plate 18. Finally, the secondary electric telescopic rod 14 is turned on. The secondary electric telescopic rod 14 drives the U-shaped pushing frame 15 to move forward. The bottom support plate 18 is movably sleeved on the rotating rod 17. Therefore, the bottom support plate 18 rotates around the rotating rod 17 as the center point. The U-shaped pushing frame 15 drives the bearings III 20 and the through rod 19 to move forward synchronously. The through rod 19 will cooperate with the activity groove 22, and finally the bottom support plate 18 is turned upward to support the bottom of the mechanical basic part template after being clamped and lifted, finally playing a role of clamping and supporting. The clamped mechanical basic part template is conveyed to the conveyor belt machine II 2 for subsequent transportation to the second inspection center. The conveyor belt machine II 2 is a belt conveyor.

[0068] During specific processing, precise detection is carried out on the machined mechanical basic parts to screen out unqualified processed products. The most effective processing efficiency is adopted, that is, the most effective processing process parameter values are used to machine the parts to achieve the maximum processing efficiency. During processing, the video monitoring module monitors the manual operation and uploads it to the storage module. A large number of processing operation methods are stored in the storage module. When the worker's operation method is incorrect, a violation signal is generated. After receiving the violation signal, the alarm module gives an alarm to warn of the safe operation of the processing personnel, so as to improve strict quality processing, increase the qualified rate of products, and further improve the processing efficiency. Cameras are set at all positions on the conveyor 1 to take pictures. When an unqualified product is detected, the drive motor 1 is controlled to start, driving the lead screw 1 to rotate, thus driving the moving plate 6 to move on the lead screw 1, and finally driving the subsequent clamping assembly to move above the mechanical basic part template. Then, the subsequent clamping work of the mechanical basic part template is completed through the clamping assembly. The conveyor 1 is a roller-type conveyor. Then, the electric telescopic rod drives the setting table 8 to move downward, and finally drives the clamping assembly to descend onto the mechanical basic part template. Then, the lead screw 2 is started to drive the two clamping plates 11 to move relative to each other on the lead screw 2, and finally cooperate with the clamping plates 11 to complete the clamping work of the mechanical basic part template. Then, the clamped mechanical basic part template is lifted. Then, the auxiliary electric telescopic rod 14 is started, and the auxiliary electric telescopic rod 14 drives the U-shaped pushing frame 15 to move forward. The bottom support plate 18 is movably sleeved on the rotating rod 17. Therefore, the bottom support plate 18 rotates around the rotating rod 17 as the center point. The U-shaped pushing frame 15 drives the bearing 3 and the through rod 19 to move forward synchronously. The through rod 19 will cooperate with the movable groove 22, and finally turn the bottom support plate 18 upward to support the bottom of the clamped and lifted mechanical basic part template, finally playing a role of clamping and supporting. The clamped mechanical basic part template is conveyed to the conveyor 2 for subsequent transportation to the second inspection center. The conveyor 2 is a belt-type conveyor.

[0069] Although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
