[0056] The gears that have passed the calibration are finally tested to ensure that they meet the specific design data of the driven gear of the drive motor shaft.

[0057] It is understandable that in the above process, the specific design data of the driven gear of the drive motor shaft can be obtained through the design drawings or CAD data, including the size, shape, tolerance and material of the gear. Subsequently, a gear blank matching the design data is prepared to ensure that the material and size of the blank meet the processing requirements.

Enhanced adaptability and flexibility: It is suitable for gear processing needs of different materials and specifications, and has strong adaptability and flexibility by adjusting processing parameters. The precise tolerance control mechanism ensures that the gears can meet various strict design requirements. In general, this embodiment not only significantly improves the processing quality and performance of the driven gear of the drive motor shaft through a systematic and refined processing control method and detection mechanism, but also improves the processing efficiency, has strong adaptability and flexibility, and can effectively meet the needs of high-performance drive motors.

[0059] In some embodiments of the present application, rough machining the gear blank to form a preliminary shape specifically includes:

[0060] After fixing the gear blank on the lathe, a suitable turning tool is selected;

[0061] According to the characteristics of the gear blank material and the tool, set the spindle speed, feed rate and cutting depth for rough machining;

[0062] After the rough machining is completed, measurement, inspection and correction processing are carried out;

[0063] The correction processing refers to the processing performed after the blank size or shape is found to have deviation after the measurement and inspection fails.

[0064] It is understood that the process of rough machining the gear blank to form a preliminary shape includes: First, fix the gear blank on the lathe to ensure the stability and safety of the blank during the machining process. According to the material of the gear blank and the characteristics of the tool, select a suitable turning tool. The selection of the turning tool is crucial to the machining quality and efficiency because it directly affects the stability of the cutting process and the quality of the machined surface. According to the material characteristics of the gear blank and the performance of the tool, set the spindle speed, feed rate and cutting depth of the rough machining. The reasonable setting of these parameters can ensure the smooth progress of the machining process while reducing tool wear and blank deformation. After setting the machining parameters, start rough machining. This step is mainly to remove excess material so that the shape of the gear roughly meets the design requirements. After the rough machining is completed, the machining results need to be measured and tested. If the measurement and inspection are unqualified, that is, it is found that there is a deviation in the size or shape of the blank, it is necessary to perform correction machining. Correction machining refers to further processing of the unqualified part to eliminate the deviation so that the size and shape of the gear meet the design requirements.

[0065] Through these steps, the machining accuracy is improved: the appropriate turning tool is selected according to the material characteristics of the gear blank, which improves the cutting efficiency and accuracy, reduces tool wear, and ensures machining accuracy. By setting appropriate spindle speed, feed speed and cutting depth, the stability and cutting effect of the tool during rough machining are ensured, and the size and shape deviations are reduced. Ensure the consistency of machining quality: ensure that the gear blank remains stable during the machining process to avoid machining errors caused by vibration or looseness. Through measurement, detection and correction machining after rough machining, deviations are discovered and corrected in time to ensure that the machining results of each gear blank are consistent, and the consistency of machining quality is improved. Improve machining efficiency: By reasonably setting the spindle speed, feed speed and cutting depth of rough machining, the machining time is optimized and the machining efficiency is improved. Through accurate measurement, detection and timely correction machining, the number of reworks caused by machining errors is reduced, and the overall machining efficiency is improved. Enhance the flexibility and adaptability of the machining process: select suitable turning tools and set machining parameters according to the material characteristics of the gear blank, which has strong adaptability and can meet the machining needs of gears of different materials and specifications. Through correction processing, the size or shape deviation is discovered and corrected in time, which improves the flexibility of the processing process and ensures that the final processing results meet the design requirements. In general, by fixing the gear blank, selecting a suitable turning tool, setting reasonable processing parameters, measuring and testing, and correcting the processing, this technical solution significantly improves the rough processing accuracy and quality of the driven gear of the drive motor shaft, ensures the consistency and stability of each gear blank, improves the overall processing efficiency, and enhances the flexibility and adaptability of the processing process.

[0066] In some embodiments of the present application, the finishing includes:

[0067] Replace the lathe and turning tool, and re-determine the spindle speed, feed rate and cutting depth for finishing;

[0068] The dimensions after finishing are inspected to ensure they meet the design requirements.

[0069] It can be understood that finishing is a more detailed and precise processing process for the gear blank to ensure that the size and quality of the final gear meet the design requirements. In the finishing stage, in order to improve the processing accuracy and surface quality, it is usually necessary to replace the lathe and turning tool with higher precision. The choice of lathe will affect the stability and accuracy of the processing, while the choice of turning tool will directly affect the quality and accuracy of the processed surface. According to the requirements of finishing, it is necessary to re-determine the processing parameters such as spindle speed, feed speed and cutting depth. The reasonable setting of these parameters is crucial to ensure the processing accuracy and surface quality. After setting the finishing parameters, start the finishing. This step is mainly to carefully cut the gear blank to achieve the design requirements of the size and surface roughness. After the finishing is completed, the size of the processed gear needs to be tested. The purpose of the test is to ensure that the size of the gear meets the design requirements, thereby ensuring the performance and reliability of the gear.

[0070] Through these steps, the processing accuracy is significantly improved: Replacing the lathe and turning tool, and selecting high-precision equipment and tools can significantly improve the processing accuracy and ensure that the size and shape of the gear are closer to the design requirements. Resetting the spindle speed, feed speed and cutting depth, and optimizing the processing parameters to further improve the processing accuracy and surface quality. Improved processing quality and consistency: Through a fine cutting process, reduce surface roughness and processing errors, ensure that the processing quality of each gear is consistent and meets the design requirements. Test the size and shape after finishing to ensure that the processing results of each gear meet the design requirements and ensure the consistency and reliability of the product. Extended equipment and tool life: By selecting a turning tool suitable for finishing and setting a suitable cutting depth, the wear and damage of the tool is reduced, and the service life of the tool is extended. Replacing with a higher-precision lathe and setting suitable processing parameters can reduce the load and wear of the equipment and extend the service life of the equipment. Improved production efficiency: Through high-precision processing and multiple inspections in the finishing stage, rework and scrap caused by processing errors are reduced, and production efficiency is improved. Optimized process parameters and equipment selection in the finishing stage make the entire processing process more efficient and stable, and improve overall production efficiency. Meet high performance requirements: Ensure that the size and shape of the gears meet the design requirements of high-performance drive motors and improve the transmission efficiency and performance of the gears. Through a fine machining process, reduce surface roughness, improve the wear resistance and service life of the gears, and meet the needs of high-performance drive motors. In general, by replacing the lathe and turning tool, resetting the spindle speed, feed speed and cutting depth of the finishing, and inspecting the dimensions after finishing, this technical solution can significantly improve the machining accuracy and quality of the driven gear of the drive motor shaft, improve production efficiency and equipment life, and ensure that the machining results meet the needs of high-performance drive motors.

[0071] In some embodiments of the present application, the spindle speed of the finishing process is faster than the spindle speed of the roughing process, the feed speed of the finishing process is slower than the feed speed of the roughing process, and the cutting depth of the finishing process is smaller than the cutting depth of the roughing process.

[0072] It is understood that in some embodiments of the present application, there are differences in the spindle speed, feed rate and cutting depth between finishing and roughing, and these differences reflect the different requirements and goals of finishing and roughing in the process. Spindle speed refers to the rotation speed of the lathe spindle, which directly affects the cutting speed and cutting force of the tool. Finishing usually requires a higher spindle speed, because finishing requires a higher cutting speed to improve processing efficiency while maintaining a lower cutting force and a higher surface quality. Feed rate refers to the speed at which the tool moves relative to the workpiece during the machining process, which affects the quality of the machined surface. The feed rate of finishing is usually slower, because slow feed helps to reduce the friction between the tool and the workpiece, thereby improving the finish and precision of the machined surface. Cutting depth refers to the depth to which the tool enters the workpiece in one cut, which affects the machining time and tool wear. The cutting depth of finishing is usually smaller, because a small cutting depth can reduce the heat and cutting force generated during the cutting process, thereby improving machining accuracy and extending tool life.

[0073] By adjusting the spindle speed, feed rate and cutting depth of finishing and roughing, in this implementation, by adopting a higher spindle speed, finishing can improve the cutting speed and processing efficiency, while maintaining a low cutting force, reducing the deformation and thermal effects of the workpiece. Slower feed speeds help reduce friction between the tool and the workpiece, improve the surface finish and precision, and ensure that the machined surface meets higher quality standards. Smaller cutting depths reduce cutting forces and heat generation, reduce tool wear, and improve processing accuracy and tool life. Overall, the optimization of these process parameters not only improves processing efficiency and product quality, but also extends the service life of equipment and tools, and significantly improves the stability and reliability of the production process.

[0074] In some embodiments of the present application, the medium-processed gear is inspected and calibrated, and the performance processing is performed after the inspection and calibration are qualified, specifically including:

[0075] Dimension detection: Use measuring tools such as vernier calipers, micrometers, inside micrometers, depth gauges, etc. to measure various dimensions of the gear, including outer diameter, inner diameter, tooth thickness, tooth pitch, tooth top height, and tooth root height;

[0076] Shape detection: Use special measuring tools such as gear measuring instrument, gear runout instrument, concentricity instrument, etc. to detect the shape and position tolerance of gears, such as roundness, concentricity, and parallelism of gears;

[0077] Surface roughness detection: Use a surface roughness meter to detect the surface roughness of the gear;

[0078] Hardness test: Use Rockwell hardness tester, Vickers hardness tester or Brinell hardness tester to test the hardness of the gear;

[0079] Gear meshing test: Use a gear tester to test the meshing performance of the gears.

[0080] In some embodiments of the present application, the meshing performance of the gear includes contact spots and meshing clearance of the gear.

[0081] It can be understood that this embodiment improves the processing accuracy and quality. Through size detection, shape detection, surface roughness detection, hardness detection and gear meshing detection, the various key parameters of the gear are comprehensively checked to ensure that they meet the design requirements and avoid various defects in the processing process. Ensure dimensional accuracy: Use measuring tools such as vernier calipers, micrometers, internal diameter micrometers and depth gauges to accurately measure the outer diameter, inner diameter, tooth thickness, tooth pitch, tooth top height and tooth root height of the gear to ensure that each dimensional parameter meets the design standard and ensure the correct assembly and operation of the gear. Ensure shape and position tolerances: Use special measuring tools such as gear measuring instruments, gear runout instruments and concentricity instruments to detect the shape and position tolerances of the gear such as roundness, concentricity and parallelism to ensure that the gear will not deviate and run during operation, thereby improving the transmission efficiency and stability of the gear. Improve surface quality and hardness: Use a surface roughness instrument to detect the roughness of the gear surface to ensure that the surface meets the design requirements for smoothness, reduce friction and wear, and increase the service life of the gear. Use Rockwell hardness tester, Vickers hardness tester or Brinell hardness tester to test the hardness of gears to ensure that the gears have sufficient strength and wear resistance to meet the load requirements in actual use. Optimize meshing performance: Use gear tester to detect the contact spots and meshing clearance of gears to ensure good meshing performance in actual operation, reduce noise and vibration during gear operation, and improve the stability and efficiency of the transmission system.

[0082] In some embodiments of the present application, the size detection and the shape detection need to compare the detection results with the specific design data of the driven gear of the drive motor shaft to ensure that the gear meets the design requirements, specifically including:

[0083] The detected size and shape data Y are compared in advance with the first preset size and shape data Y1, and the gears are divided into different tolerance levels according to the comparison result;

[0084] When the inspection size and shape data |Y-Y1| / Y1 is less than 0.1% and greater than 0.05%, the tolerance is set to the second tolerance level;

[0085] When the detected size and shape data |Y-Y1| / Y1 is less than 0.05%, the tolerance is set to the first tolerance level;

[0086] The first size and shape tolerance level is provided with a first size and shape reference parameter X1, and the second size and shape tolerance level is provided with a second size and shape reference parameter X2.

[0087] It is understandable that after the size and shape of the driven gear of the drive motor shaft are detected, the detection results are compared with the preset data, and the gears are divided into different tolerance levels according to the comparison results. Specifically, when the difference ratio between the detected size and shape data and the preset data is between 0.1% and 0.05%, the second tolerance level is set; when the difference ratio is less than 0.05%, the first tolerance level is set. At the same time, according to the tolerance level, the corresponding reference parameters X1 or X2 are set to ensure the rationality and accuracy of the tolerance setting.

[0088] In this embodiment, by comparing the size and shape detection results with the specific design data of the driven gear of the drive motor shaft, and dividing different tolerance levels according to the comparison results, some embodiments of the present application realize the refined control of gear accuracy. Specifically, it includes the following functions: improving detection accuracy and hierarchical management, and refining the division of tolerance levels by accurately comparing the detection data with the design data. When the deviation is between 0.1% and 0.05%, it is set to the second tolerance level; when the deviation is less than 0.05%, it is set to the first tolerance level. This hierarchical management makes the control of gear processing quality more refined, effectively reduces the detection error, and improves the reliability and accuracy of the detection results. Improve product quality and consistency: Through the division of tolerance levels, the gear is subjected to stricter quality control. The first tolerance level and the second tolerance level are respectively provided with corresponding reference parameters X1 and X2. Such subdivision enables the size and shape of the gear to more strictly meet the design requirements, ensuring the high consistency and high precision of the product. Improve the overall quality of the gear, making it more stable and reliable in the transmission system. Optimize the production process and reduce the scrap rate: Accurate size and shape detection, as well as strict tolerance control, enable timely detection and correction of deviations during the production process, avoiding the production of large quantities of defective products. This not only improves production efficiency, but also reduces production costs and scrap rates, significantly improving economic benefits. Enhance the performance and life of the transmission system: Through strict size and shape tolerance control, it ensures that the gears can maintain good meshing performance and stability during assembly and operation, reduces wear and failure caused by insufficient gear precision, extends the service life of the gears and the entire transmission system, and improves the overall performance of the drive motor. Support high-performance and high-demand applications: This sophisticated detection and control method is particularly suitable for drive motors and other mechanical systems with high precision and performance requirements. It can meet the needs of high-end manufacturing for high-quality and high-reliability products, and provides strong technical support for enterprises in the highly competitive market. To sum up, through the above-mentioned size and shape detection and detailed management of tolerance levels, the embodiments of the present application not only improve the processing accuracy and quality of the gears, optimize the production process, and reduce the scrap rate, but also enhance the performance and life of the transmission system, meet the needs of high-performance drive motors, and provide enterprises with significant economic benefits and competitive advantages.

[0089] In some embodiments of the present application, the surface roughness detection needs to compare the detection result with the specific design data of the driven gear of the drive motor shaft to ensure that the gear meets the design requirements, specifically including:

[0090] The surface roughness N is compared in advance with a first preset surface roughness N1, and the gear is divided into different roughness grades according to the comparison result;

[0091] When the detected surface roughness data |N-N1| is less than 1.6 microns and greater than 0.4 microns, the tolerance is set to the second surface roughness tolerance level;

[0092] When the detected surface roughness data |N-N1| is less than 0.4 microns, the tolerance is set to the first surface roughness tolerance level;

[0093] The first surface roughness tolerance level is provided with a first surface roughness reference parameter M1, and the second surface roughness tolerance level is provided with a second surface roughness reference parameter M2.

[0094] In a preferred embodiment, the surface roughness detection process involves comparing the surface roughness N of the gear with the preset first preset surface roughness N1, and dividing the gear into different roughness levels according to the comparison results. When the detected surface roughness data |N-N1| is less than 1.6 microns and greater than 0.4 microns, the second surface roughness tolerance level is set; when the detected surface roughness data |N-N1| is less than 0.4 microns, the first surface roughness tolerance level is set. At the same time, according to the roughness tolerance level, the corresponding reference parameter M1 or M2 is set to ensure the rationality and accuracy of the roughness tolerance setting.

[0095] By comparing the surface roughness test results of the gear with the design data and dividing different roughness levels according to the comparison results, some embodiments of the present application achieve fine control of the surface quality of the gear. Specifically, it includes the following aspects: accurate roughness control, comparing the surface roughness data with the preset surface roughness, and dividing it into different roughness levels according to the deviation range (such as 1.6 microns to 0.4 microns and less than 0.4 microns). This hierarchical management helps to accurately control the surface quality of the gear to meet the design requirements, thereby improving the overall processing quality and accuracy of the gear. Surface roughness optimization: By ensuring that the roughness of the gear surface is within the specified range of the design, friction, wear and noise can be reduced, the meshing performance and transmission efficiency of the gear can be improved, thereby improving the reliability and performance of the gear and the entire transmission system. Reduce production defects and improve production efficiency: By strictly controlling the surface roughness, surface quality problems that may occur during the processing process can be discovered and corrected early, thereby reducing the generation of defective products, reducing the scrap rate, and improving production efficiency. Production process optimization: The division of tolerance levels makes quality control in the production process more accurate, and can adjust the processing technology in time, optimize the production process, and improve the overall stability and efficiency of the production line. Support high-end applications and customer needs: Meet high requirements: For high-performance drive motors and other high-end applications with strict requirements on surface roughness, precise control of surface roughness can meet the high standards of these applications, improve the market competitiveness of products and customer satisfaction. Extend product service life: Controlling surface roughness can reduce friction and wear of gears during operation, extend the service life of gears and the entire transmission system, and reduce maintenance costs.

[0096] In some embodiments of the present application, the final detection specifically includes:

[0097] By calculating the qualified parameters, it is judged whether the processed driven gear of the drive motor shaft meets the requirements, and the qualified index Q is set in advance;

[0098] Q=Y*Xn+N*Mn;

[0099] Wherein, Xn represents the size and shape reference parameter, Mn represents the surface roughness reference parameter, and n=1,2.

[0100] It is understood that the final inspection is a step to determine whether the processed driven gear of the drive motor shaft meets the design requirements by calculating the qualified parameters. Specifically, the qualified index Q is pre-set, where Xn represents the size and shape reference parameter, Mn represents the surface roughness reference parameter, and n represents the serial number of the parameter. Through this formula, the final inspection combines the size and shape tolerance ladder of the gear (represented by Xn) with the surface roughness tolerance ladder (represented by Mn) to calculate a comprehensive qualified index Q. This index reflects the overall quality of the gear in terms of size, shape and surface roughness, thereby judging whether it meets the design requirements.

[0101] The final inspection process comprehensively evaluates the overall quality of the driven gear of the drive motor shaft by calculating the qualified index Q. Formula: Q=Y*Xn+N*Mn, where Xn and Mn represent the size and shape reference parameters, and the surface roughness reference parameters, respectively. Size and shape reference parameters (Xn): These parameters are used to describe the size and shape tolerances of the gear. X1, X2, etc. represent different tolerance levels, which correspond to different size and shape tolerance requirements. Surface roughness reference parameters (Mn): These parameters are used to describe the surface roughness tolerance of the gear. M1, M2, etc. represent different roughness levels, which correspond to different surface roughness requirements. Comprehensive evaluation: Comprehensive quality judgment: The qualified index Q forms a comprehensive evaluation index by comprehensively considering the quality standards of size, shape and surface roughness. This not only evaluates whether the size and shape of the gear meet the requirements, but also considers its surface quality, thereby providing a comprehensive basis for quality judgment. Overall quality reflection: The calculated Q value reflects the comprehensive quality of the gear in all aspects, ensuring the consistency and compliance of the final product in all key parameters with the design specifications. This method can effectively avoid the problem that a single parameter is not enough to fully evaluate the quality of the gear. Judgment of compliance with design requirements: Preset qualified standards: By presetting the standard of qualified index Q, it can be clearly judged whether the gear meets the design requirements. If the calculated Q value meets the preset qualified standards, it means that the gear meets the design specifications in terms of size, shape and surface roughness. Quality control: The final inspection ensures that each key parameter of the gear is effectively controlled during the production process, ensuring that the quality of the product meets the final use requirements and improving the reliability and performance of the product. Improve the production process: Optimization adjustment: If the qualified index Q fails to meet the preset standard, it may be necessary to adjust the production process or processing parameters to improve the quality of the gear. This feedback mechanism helps to continuously optimize the production process and improve overall production efficiency and product quality. By calculating the qualified index Q, the embodiment of the present application provides a method for comprehensively evaluating the overall quality of the gear. This method not only takes into account the size and shape of the gear, but also integrates the influence of surface roughness, thereby providing a comprehensive quality control indicator. This helps to ensure that the produced gears meet the design requirements in all key parameters, improves the overall quality and consistency of the product, and optimizes the production process.

[0102] The embodiment of the present invention ensures that the size, shape, surface roughness and other parameters of the driven gear of the drive motor shaft meet the design requirements through the steps of rough machining, fine machining, detection and calibration, thereby improving the machining accuracy of the gear; the present invention adopts reasonable machining parameters and machining technology, making the gear machining process more efficient and shortening the production cycle. Through strict detection, calibration and performance processing, it is ensured that the driven gear of the drive motor shaft meets the use requirements in terms of meshing, hardness and other aspects, thereby improving the reliability and service life of the gear. The present invention divides the tolerances of the size, shape and surface roughness of the gear, which is conducive to improving the interchangeability of the gear and the consistency of mass production. The machining control method proposed in the present invention has clear detection standards and a qualified index calculation formula, which is convenient for quality control of the machining process. By optimizing the machining process and reducing the scrap rate, the production cost of the driven gear of the drive motor shaft is reduced.

[0103] On the other hand, Figure 2 As shown, the embodiment of the present invention also proposes a processing control system for a driven gear of a drive motor shaft, the system comprising:

[0104] An acquisition unit, used for acquiring specific design data of a driven gear of a drive motor shaft and a gear blank;

[0105] A rough machining unit, used for rough machining the gear blank to form a preliminary shape;

[0106] A finishing unit, used for finishing the driven gear of the drive motor shaft according to the specific design data to form a medium-processed gear to achieve the required size and surface roughness;

[0107] A detection and calibration unit, used for detecting and calibrating the medium-processed gear, and performing performance processing after the detection and calibration are qualified;

[0108] The final inspection unit is used to perform a final inspection on the gear that has passed the calibration to make it meet the specific design data of the driven gear of the drive motor shaft.

[0109] It is understandable that the present invention also proposes a processing control system for a driven gear of a drive motor shaft, the system comprising: an acquisition unit: used to acquire specific design data of a driven gear of a drive motor shaft and a gear blank. The design data includes detailed information such as the size, shape, and material of the gear, while the gear blank is the original material that has not been processed. A rough processing unit: rough processing the gear blank to form a preliminary shape. This step is mainly to remove excess material so that the shape of the gear roughly meets the design requirements. A fine processing unit: fine processing the preliminarily processed gear according to the design data to form a medium-processed gear. The purpose of fine processing is to achieve the required size and surface roughness and ensure the performance and accuracy of the gear. A detection and calibration unit: detect and calibrate the medium-processed gear to ensure that its size and shape meet the design requirements. Only after the detection and calibration are qualified, the gear can proceed to the next stage of performance processing. A final detection unit: perform a final detection on the calibrated gear to ensure that it fully meets the specific design data of the driven gear of the drive motor shaft. This step is the last step to ensure the quality of the gear. Only after all the tests are qualified can the gear be considered to meet the requirements and be used to drive the motor shaft.

[0110] Through the coordinated operation of these units, the present invention provides a comprehensive and automated driving motor shaft driven gear processing control system, which can ensure that the quality and performance of the gears meet the design requirements, thereby ensuring the reliable operation of the driving motor shaft.

[0111] In summary, the present invention not only improves the machining accuracy and quality of gears and reduces production waste, but also enhances the performance and service life of gears through refined processing control, comprehensive testing and calibration, optimized production technology and strict quality control, thereby meeting the needs of high-end applications and improving market competitiveness.
