Description

Technical Field

[0001] The present invention relates to the technical field of quenching equipment for motor drive shafts, and in particular to a quenching processing control method and system for a motor drive shaft. Background Art

[0002] In the production and processing of motor drive shafts, quenching treatment is an important link, which can improve the hardness, strength and wear resistance of the motor drive shaft, thereby improving the service life and performance of the motor drive shaft.

[0003] Quenching is a heat treatment process by which the motor drive shaft is heated at an extremely high temperature and then quickly immersed in a cooling medium to achieve rapid cooling. This process can effectively improve the organizational structure of the motor drive shaft and improve its mechanical properties.

[0004] At present, although the existing quenching equipment for motor drive shafts meets the production needs to a certain extent, there are still many areas that need to be improved. For example, during the quenching process, due to the inaccurate control of the heating temperature, the motor drive shaft may fail to reach the ideal temperature range during the quenching process, thereby affecting its organizational structure and performance. Secondly, the temperature management of the quenching liquid is not satisfactory. If the quenching liquid temperature is too low, it may cause uneven cooling during the quenching process, resulting in irregular deformation or cracks. These problems not only affect the service life of the motor drive shaft, but also its working performance. At the same time, the traditional quenching equipment cannot monitor and adjust the quenching liquid and heating temperature in real time, resulting in instability in process control. This lack of control accuracy makes it difficult to achieve uniform heating and cooling during the quenching process, which in turn makes it difficult to guarantee the quality and consistency of the final product.

[0005] In view of the fact that the quenching equipment in the current technology has the defects of insufficient precision of heating temperature and quenching liquid temperature during operation, as well as poor control effect of these two key parameters, we urgently need to develop a new motor drive shaft quenching equipment. This equipment is designed to solve the above problems, ensure that the heating temperature and quenching liquid temperature can be accurately controlled, thereby optimizing the quenching process and improving product quality.

This precise heating control not only improves the stability of the quenching process, but also effectively reduces the risk of deformation or cracking caused by local overheating or overcooling, thereby significantly improving the quality of the final product. Secondly, the design of the quenching liquid injection module further optimizes the cooling effect of the quenching process. The module is not only equipped with a liquid heating unit to ensure the temperature stability of the quenching liquid, but also can uniformly spray the quenching liquid during the quenching process, thereby avoiding the processing defects caused by uneven cooling in traditional equipment. This fine injection control effectively improves the cooling uniformity of the motor drive shaft and improves the consistency and effect of the quenching process. Finally, the environmental protection and economy of the system are improved through the integrated design of the quenching liquid storage box and the recovery module. The quenching liquid storage tank ensures sufficient supply of quenching liquid, while the recovery module effectively collects and recycles waste liquid inside the quenching space. This design not only reduces resource waste, but also reduces the impact on the environment, which meets the requirements of modern manufacturing industry for sustainable development.

[0056] On the other hand, the present application also provides a quenching control method for a motor drive shaft, comprising:

The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0068] like Figure 1 As shown, in some embodiments of the present application, this embodiment provides a quenching processing control system for a motor drive shaft, including: a quenching furnace 100 and a control module: the quenching furnace 100 is used to quench the motor drive shaft; the control module is electrically connected to the quenching furnace 100, so that when the quenching furnace 100 quenches the motor drive shaft, the control module is used to control the quenching liquid temperature and the quenching temperature during quenching.

[0069] Specifically, the quenching furnace 100 includes: a furnace body, a movable rail 120, a movable clamp 130, a heating module 140, a quenching liquid injection module 150, a quenching liquid storage box and a quenching liquid recovery module 170. A quenching space is arranged inside the furnace body, and a pressure relief valve is arranged on the top of the furnace body; the movable rail 120 is arranged inside the quenching space along the setting direction of the furnace body, and the movable rail 120 is fixedly connected to the inner wall of the quenching space; one end of the movable clamp 130 is arranged inside the movable rail 120, and the movable clamp 130 is movably connected to the movable rail 120, wherein the movable clamp 130 is used to clamp the motor drive shaft; the heating module 140 is arranged between the two clamping claws of the movable clamp 130, and one end of the heating module 140 is connected to the inner wall of the quenching space, wherein a heating hole is opened in the middle of the heating module 140, and the heating hole is arranged corresponding to the clamping area of ​​the clamping claw, so that when the movable clamp 130 drives the motor drive shaft to move along the setting direction of the movable rail 120, The heating module 140 is used to heat the motor drive shaft; the quenching liquid injection module 150 is arranged below the heating module 140, and one end of the quenching liquid injection module 150 is connected to the heating module 140, wherein the quenching liquid injection module 150 is provided with a liquid heating unit, and the quenching liquid injection module 150 is used to spray quenching liquid; the quenching liquid storage box is arranged on the outside of the furnace body, and the quenching liquid storage box is connected to the outer wall of the furnace body, and the guide end of the quenching liquid storage box passes through the outer wall of the furnace body and is connected to the other end of the quenching liquid injection module 150, and the quenching liquid storage box is used to supply quenching liquid to the quenching liquid injection module 150; the quenching liquid recovery module 170 is arranged on the inner bottom surface of the quenching space, and the quenching liquid recovery module 170 is used to collect the quenching liquid inside the quenching space.

[0070] See also Figure 2Specifically, the control module includes: a water temperature detection unit, an image acquisition unit, a thermal imaging detection unit and a central control unit. The water temperature detection unit is arranged inside the quenching liquid storage box, and the water temperature detection unit is used to detect the temperature of the quenching liquid; the image acquisition unit is arranged at one end of the mobile fixture 130, and the image acquisition unit is used to obtain the texture image of the cross section of the motor drive shaft; the thermal imaging detection unit is used to obtain the temperature of each area when the motor drive shaft is heated and the real-time temperature of the quenching space; the central control unit is respectively connected to the heating module 140, the liquid heating unit, the water temperature detection unit, the image acquisition unit and the thermal imaging detection unit, and the central control unit is used to determine the material of the motor drive shaft according to the texture image of the cross section of the motor drive shaft, and determine the initial heating temperature of the heating module 140 according to the material of the motor drive shaft; the central control unit is also used to determine the liquid temperature of the quenching liquid according to the heating temperature of the heating module 140 and the real-time temperature of the quenching space; the central control unit is also used to adjust the initial heating temperature of the heating module 140 according to the liquid temperature of the quenching liquid and the temperature of each area when the motor drive shaft is heated.

[0071] It can be seen that the water temperature detection unit in the control module is responsible for real-time monitoring of the temperature of the quenching liquid. This function is crucial because the temperature of the quenching liquid directly affects the cooling rate and the final processing effect. By accurately detecting the temperature of the quenching liquid, the system can dynamically adjust the output of the liquid heating unit to keep the quenching liquid within the set ideal temperature range and prevent uneven cooling caused by temperature fluctuations. Secondly, the image acquisition unit is used to obtain the texture image of the cross section of the motor drive shaft. By analyzing these images, the central control unit can determine the material of the motor drive shaft. This information is crucial for setting the initial heating temperature because metals of different materials require different heating temperatures and cooling conditions. Ensuring that the heating temperature matches the characteristics of the material can effectively reduce deformation and cracks caused by improper temperature. At the same time, the thermal imaging detection unit is responsible for obtaining real-time temperature data of the motor drive shaft and the quenching space. These data are used to monitor the temperature distribution during the heating process and adjust the working state of the heating module 140 in real time. By accurately monitoring the temperature of each area, the system can ensure the heating uniformity of the heating module 140, thereby improving the stability and consistency of the entire quenching process. Finally, the central control unit plays a command and dispatching role in the entire system. It not only sets the initial heating temperature of the heating module 140 according to the material information provided by the image acquisition unit, but also adjusts the temperature of the quenching liquid and the working parameters of the heating module 140 according to the data provided by the thermal imaging detection unit and the water temperature detection unit. The intelligent adjustment function of the central control unit ensures that both heating and cooling can be carried out under the best conditions during the quenching process, thereby optimizing the final performance and quality of the motor drive shaft.

[0072] It is understandable that precise temperature control and real-time adjustment significantly improve the uniformity of the heating and cooling process, reduce deformation and cracks caused by temperature instability, and improve the processing quality of the motor drive shaft. Secondly, through intelligent material recognition and dynamic adjustment, the system can optimize the management of heating and quenching liquid according to the specific characteristics of the motor drive shaft, thereby further improving the consistency and reliability of processing. In addition, the system's degree of automation improves production efficiency, reduces the need for manual intervention, and also enhances the stability and repeatability of the production process, meeting the requirements of modern manufacturing for high precision and high efficiency.

[0073] In some embodiments of the present application, the central control unit includes: an acquisition subunit, a first analysis subunit, a second analysis subunit and a control subunit. The acquisition subunit is electrically connected to the water temperature detection unit, the image acquisition unit and the thermal imaging detection unit respectively, and the acquisition subunit is used to acquire the temperature of the quenching liquid, the texture image of the cross section of the motor drive shaft, the temperature of each region when the motor drive shaft is heated, and the real-time temperature of the quenching space. The first analysis subunit is electrically connected to the acquisition subunit, and the first analysis subunit is used to determine the material of the motor drive shaft according to the texture image of the cross section of the motor drive shaft, and determine the initial heating temperature of the heating module 140 according to the material of the motor drive shaft. The first analysis subunit is also used to adjust the initial heating temperature according to the liquid temperature of the quenching liquid and the temperature of each region when the motor drive shaft is heated, and determine the adjusted initial heating temperature as the heating temperature of the heating module 140. The second analysis subunit is electrically connected to the acquisition subunit and the first analysis subunit respectively, and the second analysis subunit is used to determine the temperature of the quenching liquid according to the heating temperature and the real-time temperature of the quenching space. The control subunit is electrically connected to the first analysis subunit, the second analysis subunit, the heating module 140 and the liquid heating unit, respectively, and is used to control the heating module 140 to heat according to the heating temperature determined by the first analysis subunit. The control subunit is also used to control the liquid heating unit to heat the quenching liquid according to the temperature of the quenching liquid determined by the second analysis subunit.

[0074] Specifically, the acquisition subunit, as the core part of information collection, collects key data in real time through the connection with the water temperature detection unit, the image acquisition unit and the thermal imaging detection unit. These data include the temperature of the quenching liquid, the texture image of the motor drive shaft section, the temperature of each area during the heating process, and the real-time temperature of the quenching space. These information are the basis for ensuring the smooth progress of the entire quenching process, and they provide the necessary basis for subsequent analysis and regulation. Next, the first analysis subunit uses the data provided by the acquisition subunit for detailed analysis. It first determines the material type based on the texture image of the motor drive shaft section and sets the initial heating temperature accordingly. For different materials of the motor drive shaft, the system can automatically adjust the heating temperature to match the material properties. In addition, the first analysis subunit will also consider the liquid temperature of the quenching liquid and the temperature of each area when the motor drive shaft is heated, and fine-tune the initial heating temperature to ensure that the heat provided by the heating module 140 is uniform and meets the requirements. This dynamic adjustment capability ensures that the motor drive shaft can obtain a consistent and appropriate temperature distribution during the heating process. The second analysis subunit further analyzes the real-time data during the heating process based on the first analysis subunit. It combines the heating temperature and the real-time temperature of the quenching space to calculate the most suitable quenching liquid temperature. This process is crucial because the temperature of the quenching liquid directly affects the cooling rate and the final material properties. Through accurate temperature calculation, the second analysis subunit helps ensure that the temperature of the quenching liquid is always in the optimal range, thereby improving the consistency and reliability of the quenching effect. Finally, the control subunit applies the results from the first analysis subunit and the second analysis subunit to actual operation. It accurately controls the heating temperature and the quenching liquid temperature by adjusting the working status of the heating module 140 and the liquid heating unit. The control subunit is responsible for adjusting the output of the heating module 140 in real time to ensure that the motor drive shaft is evenly heated throughout the heating process; at the same time, it also controls the liquid heating unit to keep the temperature of the quenching liquid within a predetermined range. This sophisticated control mechanism not only improves the level of automation in the production process, but also greatly improves the quality and consistency of the final product.

[0075] Specifically, when the first analysis subunit is used to determine the initial heating temperature of the heating module 140 according to the material of the motor drive shaft, it includes: the first analysis subunit is also used to compare the texture image of the motor drive shaft with the texture images of each preset material configured by the first analysis subunit, wherein: if the texture image is consistent with any preset material texture image, the first analysis subunit determines the heating temperature configured corresponding to the preset material texture image as the initial heating temperature. If the texture image is inconsistent with each preset material texture image, the first analysis subunit obtains the similarity between the texture image and each preset material texture image, and sorts the similarity between the texture image and each preset material texture image in reverse order, and the first analysis subunit is also used to obtain the preset material texture image ranked as the first similarity, and determine the heating temperature configured corresponding to the preset material texture image as the initial heating temperature.

[0076] Specifically, the first analysis subunit is also used to obtain the preset material texture image with the first similarity ranking, and determine the heating temperature corresponding to the preset material texture image as the initial heating temperature, including: the first analysis subunit is also used to obtain the number of preset material texture images with the first similarity ranking, wherein: when the number is equal to 1, the first analysis subunit determines the heating temperature corresponding to the preset material texture image as the initial heating temperature. When the number is greater than 1, the first analysis subunit obtains the preset material texture images whose colors are consistent with the color of the texture image, and determines the heating temperature corresponding to the preset material texture image as the initial heating temperature.

[0077] It can be seen that the material type of the motor drive shaft is determined by comparing the texture image of the motor drive shaft with a series of preset material texture images one by one, and using image recognition technology. If the texture image of the motor drive shaft is completely consistent with a preset texture image, the first analysis subunit will directly adopt the heating temperature corresponding to the preset material. This process is fast and efficient, and can reduce manual intervention and errors while ensuring the accuracy of the heating temperature. However, in practical applications, the texture image of the motor drive shaft may not be completely consistent with all the preset texture images. In this case, the first analysis subunit will calculate the similarity between the texture image of the motor drive shaft and each preset texture image, and sort them in reverse order of similarity. This process allows the first analysis subunit to select the preset material texture image with the highest similarity. The heating temperature corresponding to the image will be selected as the initial heating temperature, thereby ensuring the scientificity and rationality of the temperature setting. Further, when the number of preset material texture images ranked as the first similarity is not unique, the first analysis subunit will perform color analysis on these images. Specifically, the first analysis subunit compares the colors of these images with the colors of the motor drive shaft texture image, and selects the heating temperature of the preset material texture image with the same color as the final initial heating temperature. This additional color consistency check step further improves the system's recognition accuracy of the material and ensures that the selection of the heating temperature is more in line with actual needs.

[0078] In some embodiments of the present application, when the first analysis subunit is also used to adjust the initial heating temperature according to the liquid temperature of the quenching liquid and the temperature of each area when the motor drive shaft is heated, it includes: the first analysis subunit is also used to obtain the real-time liquid temperature of the quenching liquid, and determine whether to adjust the initial heating temperature according to the relationship between the real-time liquid temperature and the preset liquid temperature configured corresponding to the initial heating temperature. When the real-time liquid temperature is equal to or greater than the preset liquid temperature, the first analysis subunit determines not to adjust the initial heating temperature. When the real-time liquid temperature is less than the preset liquid temperature, the first analysis subunit determines the adjustment coefficient for adjusting the initial heating temperature according to the liquid temperature difference between the real-time liquid temperature and the preset liquid temperature, and adjusts the initial heating temperature according to the adjustment coefficient.

[0079] Specifically, when the first analysis subunit determines the adjustment coefficient of the initial heating temperature, it includes: the first analysis subunit is also used to determine the axis of the heating position of the motor drive shaft as the center point, and divide the detection area according to the radius of the heating position and the center point. The first analysis subunit is also used to obtain the real-time time when the temperature of each detection area is consistent during heating. The first analysis subunit is also used to determine whether to correct the adjustment coefficient based on the relationship between the real-time time and the preset time configured by the first analysis subunit, wherein: when the time is less than or equal to the preset time, the first analysis subunit determines not to correct the adjustment coefficient. When the time is higher than the preset time, the first analysis subunit determines the correction coefficient when correcting the adjustment coefficient, and corrects the adjustment coefficient according to the correction coefficient.

[0080] It is understandable that the liquid temperature of the quenching liquid is obtained in real time by the first analysis subunit and compared with the preset liquid temperature. This process ensures that the first analysis subunit can track the state of the quenching liquid in real time and respond to temperature changes in a timely manner. When the real-time liquid temperature is equal to or higher than the preset liquid temperature, the system considers that the current heating conditions are sufficient and there is no need to adjust the initial heating temperature. This mechanism effectively avoids unnecessary temperature adjustments and ensures the stability of the heating process. However, if the real-time liquid temperature is lower than the preset liquid temperature, the first analysis subunit will further calculate the difference in liquid temperature and determine the adjustment coefficient based on this difference. This adjustment coefficient will be used to correct the initial heating temperature to compensate for the insufficient or uneven heating problems that may be caused by the liquid temperature deviation. Through this intelligent adjustment mechanism, the system can dynamically optimize the heating temperature in actual operation to adapt to the changing quenching liquid temperature, thereby improving the overall processing quality. In order to improve the accuracy of the adjustment, the first analysis subunit also introduces the detection area division based on the heating position and the analysis of the time taken. Specifically, the first analysis subunit determines the center point of the heating position of the motor drive shaft and divides multiple detection areas according to this center point and the radius of the heating position. The temperatures of these detection areas are monitored in real time to obtain the time taken during the heating process. These data help to evaluate the temperature distribution during the heating process and further optimize the heating process. When there is a difference between the actual time taken and the preset time taken, the first analysis subunit will decide whether the adjustment coefficient needs to be corrected. If the actual time taken exceeds the preset value, it means that the heating process may be uneven or delayed. At this time, the first analysis subunit will calculate the correction coefficient and correct the adjustment coefficient. In this way, the first analysis subunit can make real-time adjustments based on the actual heating situation to ensure the accuracy of temperature control.

[0081] In some embodiments of the present application, when the second analysis subunit is used to determine the temperature of the quenching liquid according to the heating temperature and the real-time temperature of the quenching space, it includes: the second analysis subunit is also used to obtain the real-time temperature of the heating temperature, and determine the temperature of the quenching liquid according to the relationship between the real-time temperature and the initial heating temperature: when the real-time temperature is lower than or equal to the initial heating temperature, the second analysis unit determines that the real-time temperature of the quenching liquid is the temperature of the quenching liquid. When the real-time temperature is higher than the initial heating temperature, the second analysis unit adjusts the real-time temperature of the quenching liquid according to the temperature difference between the real-time temperature and the initial heating temperature, and determines that the adjusted real-time temperature of the quenching liquid is the temperature of the quenching liquid.

[0082] Specifically, when the second analysis subunit determines the temperature of the quenching liquid, it includes: the second analysis subunit is also used to obtain the real-time ambient temperature of the quenching space, and determine whether to adjust the temperature of the quenching liquid according to the relationship between the real-time ambient temperature and the preset ambient temperature configured by the second analysis subunit: when the real-time ambient temperature is lower than or equal to the preset ambient temperature, the second analysis subunit determines not to adjust the temperature of the quenching liquid. When the real-time ambient temperature is higher than the preset ambient temperature, the second analysis subunit determines the adjustment coefficient of the temperature of the quenching liquid according to the ambient temperature difference between the real-time ambient temperature and the preset ambient temperature, and adjusts the temperature of the quenching liquid according to the adjustment coefficient.

[0083] It is understandable that the second analysis subunit monitors the actual effect of the heating process by obtaining the real-time heating temperature and comparing it with the initial heating temperature. When the real-time temperature is lower than or equal to the initial heating temperature, the system directly uses the real-time temperature as the temperature of the quenching liquid. This process ensures that the quenching liquid temperature matches the temperature of the heating source, thereby effectively avoiding the problem of temperature inconsistency. The tracking and immediate application of the real-time temperature make the temperature control during the quenching process more accurate and ensure the uniformity and consistency of heating. However, when the real-time temperature is higher than the initial heating temperature, the second analysis subunit will adjust the temperature of the quenching liquid by calculating the temperature difference between the two. Specifically, the system will calculate an adjustment coefficient based on the temperature difference and use this coefficient to make necessary corrections to the temperature of the quenching liquid. This adjustment mechanism can effectively compensate for the possible impact caused by excessive heating temperature and ensure that the quenching liquid temperature will not cause processing quality problems due to excessive heating. In order to further improve the temperature adjustment accuracy of the second analysis subunit, the second analysis subunit also considers the impact of the ambient temperature of the quenching space on the liquid temperature. The system monitors the ambient temperature in real time and compares it with the preset ambient temperature. If the real-time ambient temperature is higher than the preset ambient temperature, the system will calculate an ambient temperature difference and determine the adjustment coefficient of the quenching liquid temperature accordingly. This mechanism allows the system to dynamically adjust the liquid temperature according to the actual ambient conditions, further optimizing the temperature control during the quenching process.

[0084] In the above embodiment, by optimizing the design of the heating module 140 and the mobile fixture 130, the system can achieve uniform heating of the motor drive shaft during the quenching process. The heating hole opened in the middle of the heating module 140 can be precisely docked with the clamping area of ​​the clamping claw, thereby ensuring that the motor drive shaft obtains uniform heat distribution during the entire heating process. This precise heating control not only improves the stability of the quenching process, but also effectively reduces the risk of deformation or cracking caused by local overheating or overcooling, thereby significantly improving the quality of the final product. Secondly, the design of the quenching liquid injection module 150 further optimizes the cooling effect of the quenching process. The module is not only equipped with a liquid heating unit to ensure the temperature stability of the quenching liquid, but also can uniformly spray the quenching liquid during the quenching process, thereby avoiding processing defects caused by uneven cooling in traditional equipment. This fine injection control effectively improves the cooling uniformity of the motor drive shaft and improves the consistency and effect of the quenching process. Finally, the integrated design of the quenching liquid storage box and the recovery module improves the environmental protection and economy of the system. The quenching liquid storage tank ensures sufficient supply of quenching liquid, while the recovery module effectively collects and recycles waste liquid inside the quenching space. This design not only reduces resource waste, but also reduces the impact on the environment, which meets the requirements of modern manufacturing industry for sustainable development.
