Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bearing manufacturing, in particular to a manufacturing method and system of a single-rod bearing, an intelligent terminal and a storage medium. BACKGROUND

[0002] A bearing is a mechanical part, and its core function is to reduce the frictional resistance between moving parts and support rotating parts. A single-rod bearing is a common bearing, which is composed of a single rod, a rolling element and a shell.

[0003] In related technologies, a single rod is manufactured first when manufacturing a single-rod bearing. The raw material is subjected to turning and grinding to obtain a single rod. Then the single rod, the rolling element and the shell are combined to obtain a single-rod bearing.

[0004] According to the related technologies described above, the strength of the single rod itself is relatively limited, which can cause the overall strength of the single-rod bearing to decrease. SUMMARY

[0005] In order to improve the overall strength of the single-rod bearing, the present application provides a manufacturing method and system of a single-rod bearing, an intelligent terminal and a storage medium.

[0006] In a first aspect, the present application provides a manufacturing method of a single-rod bearing, which adopts the following technical solution:

[0007] A manufacturing method of a single-rod bearing, comprising:

[0008] Firstly, a first turning process is performed on a single rod to be processed to obtain a first processed single rod, and the first turning process is used to remove excess material on the single rod to be processed;

[0009] Secondly, a second turning process is performed on the first processed single rod to obtain a second processed single rod, and the second turning process is used to remove excess material on the first processed single rod;

[0010] Thirdly, quenching treatment is performed on the second processed single rod to obtain an initial quenched single rod;

[0011] Fourthly, size information of the initial quenched single rod is obtained;

[0012] Fifthly, according to the size information, correction treatment is performed on the initial quenched single rod to obtain a corrected quenched single rod;

[0013] Finally, the corrected quenched single rod, a rolling element and a shell are combined to obtain a single-rod bearing.

[0014] By adopting the technical scheme, through sequentially performing twice turning processing, the excess material on the single rod can be accurately and efficiently removed, laying a good foundation for subsequent processing. Then, the single rod after turning is subjected to quenching treatment, which can significantly improve the hardness and wear resistance of the surface of the single rod, thereby greatly enhancing the overall mechanical strength and load capacity of the finally manufactured single rod bearing, and prolonging the service life thereof. After quenching, by acquiring the size information of the initial quenched single rod and performing targeted correction treatment according to the size information, the deformation and size deviation caused by the quenching process can be effectively compensated and corrected, so as to ensure the size precision of the single rod. Finally, the corrected quenched single rod with the required precision is assembled with the rolling element and the shell, so as to ensure the assembly precision and running stability of the bearing. The method has clear process flow, and takes into account the strength improvement and precision control, thereby effectively improving the product quality and performance consistency of the single rod bearing.

[0015] Optionally, the size information is compared with a preset standard size to obtain a size difference value and a single rod region corresponding to the size difference value;

[0016] A problem size difference value greater than a preset size difference value threshold is determined from the size difference value;

[0017] A problem single rod region in the initial quenched single rod is determined according to the problem size difference value and the single rod region;

[0018] The problem single rod region is subjected to grinding treatment to obtain the corrected quenched single rod.

[0019] By adopting the technical scheme, by comparing the size information of the initial quenched single rod with the preset standard size, the size difference value and the specific single rod region corresponding thereto can be accurately acquired, and the deviation is positioned. Further, by setting the preset size difference value threshold to screen out the problem size difference value exceeding the allowable range, and determining the problem single rod region according to the problem size difference value, the subsequent processing target is clear, unnecessary full-size processing is avoided, and the processing efficiency is improved. Finally, the grinding treatment is performed on the identified problem region to realize fine and localized correction, effectively correcting the out-of-tolerance parts caused by quenching deformation or other processing errors to the qualified range, thereby ensuring the processing efficiency while significantly improving the size precision and qualification rate of the single rod.

[0020] Optionally, in the case that there are at least two problem single rod regions, the problem single rod regions are numbered;

[0021] The processing rotation speed is acquired;

[0022] The selecting step is performed, and the selecting step includes: selecting an i th problem single rod region and an i+1 th problem single rod region in the problem single rod region;

[0023] performing a first obtaining step, the first obtaining step comprising: obtaining an axial distance from the ith problematic single-bar region to the (i+1)th problematic single-bar region;

[0024] performing a second obtaining step, the second obtaining step comprising: obtaining a deviation angle between the ith problematic single-bar region and the (i+1)th problematic single-bar region, the deviation angle representing an angular difference between the ith problematic single-bar region and the (i+1)th problematic single-bar region in the axial direction;

[0025] performing a calculating step, the calculating step comprising: obtaining an ith machining moving speed corresponding to the ith problematic single-bar region according to the machining rotating speed, the axial distance, and the deviation angle;

[0026] performing an updating step, the updating step comprising: adding the ith machining moving speed to a machining moving speed set;

[0027] updating i to i+1, and repeating the selecting step, the first obtaining step, the second obtaining step, the calculating step, and the updating step until each problematic single-bar region is traversed, so as to obtain the machining moving speed set, wherein a difference between adjacent machining moving speeds in the machining moving speed set is less than a preset moving speed difference;

[0028] controlling a grinding device to perform grinding processing according to the machining moving speed set and the machining rotating speed, so as to obtain the corrected quenched single bar.

[0029] By using the above technical solution, when there are multiple problematic regions to be processed, the numbering management is adopted to achieve the orderliness of the machining process. By comprehensively considering the machining rotating speed, the axial distance between adjacent problematic regions, and the deviation angle between the two in the circumferential direction, a specific machining moving speed for the ith problematic region is calculated, and the moving speed change between the continuous machining regions is ensured to be smooth, forming an optimized machining moving speed set. This method can guide the grinding device to dynamically adjust the moving speed according to different local geometric characteristics, avoid the unstable machining quality or equipment vibration caused by sudden speed change, and realize high-speed, smooth, and accurate continuous grinding correction, thereby significantly improving the correction efficiency and surface treatment consistency for complex deviation distribution.

[0030] Optionally, an (i-1)th machining moving speed corresponding to an (i-1)th problematic single-bar region is obtained;

[0031] a recommended machining moving speed interval is obtained;

[0032] a deviation angle set is generated according to the deviation angle;

[0033] a predicted moving time set is obtained according to the deviation angle set and the machining rotating speed;

[0034] According to the set of predicted moving time lengths and the axial distance, a set of machining moving speeds is obtained;

[0035] The i-th machining moving speed is determined in the set of machining moving speeds, so that the i-th machining moving speed falls into the recommended machining moving speed interval, and the difference between the i-th machining moving speed and the (i-1)-th machining moving speed is less than the preset moving speed difference value.

[0036] By adopting the above technical solution, the determination strategy of the machining moving speed is further refined. By referring to the machining moving speed of the previous problem area and combining the recommended machining moving speed interval, the coherence and rationality of the machining parameter setting are ensured. Based on the set of deviation angles and the machining rotating speed, the set of predicted moving time lengths is calculated, and then the set of machining moving speeds is calculated according to the axial distance. This process is based on the systematic calculation of multiple parameters, so that the i-th machining moving speed determined finally not only meets the machining requirements of the current area, but also smoothly connects with the machining moving speed of the previous area. This method effectively reduces the speed fluctuation in the machining process, ensures the smoothness of the motion of the grinding equipment during the transition between different problem areas, and thus improves the overall quality consistency of the machined surface.

[0037] Optionally, if the i-th machining moving speed is not determined in the set of machining moving speeds, a candidate machining moving speed closest to the recommended machining moving speed interval is determined in the set of machining moving speeds.

[0038] According to the candidate machining moving speed and the set of deviation angles, a set of candidate machining rotating speeds is generated;

[0039] A target rotating speed with the smallest difference from the machining rotating speed is determined in the set of machining rotating speeds.

[0040] In the case where the grinding equipment approaches the i-th problem single rod area, the rotating speed of the grinding equipment is adjusted to the target rotating speed.

[0041] By adopting the above technical solution, when the ideal value that meets the recommended moving speed interval and ensures the smooth transition of the moving speed cannot be calculated, this method first selects the candidate machining moving speed closest to the recommended interval. Then, the possible set of candidate machining rotating speeds is deduced in reverse from the candidate moving speed and the set of deviation angles, and the target rotating speed closest to the currently set machining rotating speed is selected. Finally, when the grinding equipment is about to machine the problem area, the rotating speed of the equipment is dynamically adjusted instead of the moving speed. This flexible coping strategy ensures that even in the case of limited calculation, the best machining condition can be approached by optimizing another key parameter, which guarantees the grinding correction effect of the problem area and improves the robustness and adaptability of the method.

[0042] Optionally, a machining influence area corresponding to the problem single rod area on the initial quenched single rod is obtained.

[0043] According to the preset standard size, it is judged whether there is an over-affected area in the machining affected area, and the over-affected area has a quenching layer thickness less than a preset minimum size;

[0044] If yes, the maximum length and the coverage angle of the problem single rod area along the axial direction are obtained;

[0045] According to the machining speed, the maximum length and the coverage angle, an adjustment length is generated;

[0046] The grinding equipment is controlled to adjust the initial quenching single rod to reciprocate according to the adjustment length.

[0047] By adopting the above technical solution, the size too small area possibly generated by excessive grinding around the correction area is identified, the characteristic parameters of the original problem area are obtained, the optimized grinding adjustment length is calculated in combination with the machining speed, and the grinding equipment is controlled to reciprocate according to the corresponding length. This operation can compensate and finish the potential over-grinding area, effectively eliminate the hidden danger of local stress concentration or size unqualified, ensure the size uniformity and geometric integrity of the entire single rod shaft, and further improve the reliability and safety of the final product.

[0048] Optionally, a machining image of the corrected quenching single rod is obtained;

[0049] The correction condition of the corrected quenching single rod is obtained through the machining image;

[0050] If the correction condition does not meet the preset standard size, a correction area is determined on the corrected quenching single rod according to the correction condition;

[0051] According to the correction area, the correction processing of the initial quenching single rod is adjusted.

[0052] By adopting the above technical solution, the machining image of the corrected quenching single rod is obtained, and the correction condition is analyzed, so that the effect of the previous correction processing can be inspected and evaluated in real time. If it is found that the correction result does not meet the preset standard, the correction area that needs to be processed again can be accurately positioned according to the image analysis result, and the subsequent correction processing parameters or strategies are adjusted according to the feedback information. This closed-loop quality control method based on visual detection can timely find and correct the deviation, realize self-optimization and adjustment of the manufacturing process, significantly reduce the waste rate, and ensure the consistency and high quality of single rod bearing manufacturing.

[0053] In a second aspect, the application provides a single rod bearing manufacturing system, which adopts the following technical solution:

[0054] A single rod bearing manufacturing system, comprising:

[0055] An acquisition module is configured to acquire the size information.

[0056] A memory is configured to store a program of the manufacturing method of the single-rod bearing.

[0057] A processor is configured to load and execute the program in the memory to implement the manufacturing method of the single-rod bearing.

[0058] By using the above technical solution, the two turning processes are sequentially performed to accurately and efficiently remove the excess material on the single rod, thereby laying a good foundation for subsequent processing. Then, the turned single rod is subjected to quenching treatment, which can significantly improve the hardness and wear resistance of the surface of the single rod, thereby greatly enhancing the overall mechanical strength and load-carrying capacity of the finally manufactured single-rod bearing and prolonging the service life thereof. After quenching, the size information of the initial quenched single rod is acquired, and targeted correction treatment is performed based on the size information, so that the deformation and size deviation caused by the quenching process can be effectively compensated and corrected, thereby ensuring the size precision of the single rod. Finally, the corrected quenched single rod with the required precision is assembled with the rolling element and the shell to ensure the assembly precision and running stability of the bearing. The method has a clear process and takes into account the strength improvement and precision control, thereby effectively improving the product quality and performance consistency of the single-rod bearing.

[0059] In a third aspect, the present application provides an intelligent terminal, which adopts the following technical solution:

[0060] An intelligent terminal includes a memory and a processor, and the memory stores a computer program capable of being loaded and executed by the processor to implement the method according to any one of the above.

[0061] In a fourth aspect, the present application provides a computer storage medium capable of storing a corresponding program, which has the characteristics of facilitating the improvement of the overall strength of the single-rod bearing, and adopts the following technical solution:

[0062] A computer-readable storage medium stores a computer program capable of being loaded and executed by a processor to implement any one of the above manufacturing methods of the single-rod bearing.

[0063] In summary, the present application has at least one of the following beneficial technical effects:

[0064] 1. By sequentially performing two turning processes, the excess material on the single rod can be accurately and efficiently removed, laying a good foundation for subsequent processing. Subsequently, the single rod after turning is subjected to quenching treatment, which can significantly improve the hardness and wear resistance of the surface of the single rod, thereby greatly enhancing the overall mechanical strength and load-carrying capacity of the finally manufactured single rod bearing, and prolonging its service life. After quenching, by obtaining the size information of the initial quenched single rod and performing targeted correction treatment accordingly, the deformation and size deviation caused by the quenching process can be effectively compensated and corrected, ensuring the size accuracy of the single rod. Finally, the corrected quenched single rod with the required accuracy is assembled with the rolling element and the shell, ensuring the assembly accuracy and running stability of the bearing. The method has clear process flow, and takes into account the strength improvement and accuracy control, effectively improving the product quality and performance consistency of the single rod bearing;

[0065] 2. By comparing the size information of the initial quenched single rod with the preset standard size, the size difference and its corresponding specific single rod area can be accurately obtained, realizing the positioning of the deviation. Further, by setting a preset size difference threshold to screen out problem size differences that exceed the allowed range, and determining the problem single rod area accordingly, the target of subsequent processing is clear, avoiding unnecessary full-size processing and improving processing efficiency. Finally, the identified problem area is subjected to grinding treatment, realizing fine and localized correction, effectively correcting the out-of-tolerance parts caused by quenching deformation or other processing errors to the qualified range, thereby ensuring the processing efficiency while significantly improving the size accuracy and qualification rate of the single rod.

[0075] For the purpose, technical solutions and advantages of the present application to be more clearly understood, the following further describes the present application in detail with reference to the accompanying drawings and embodiments. Figure 1 to Figure 9 and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not intended to limit the present application.

[0076] An embodiment of the present application discloses a single rod bearing manufacturing method. Referring to Figure 1 , the method comprises:

[0077] Step S101: performing first turning processing on a single rod to be processed to obtain a first processed single rod, the first turning processing being used to remove excess material on the single rod to be processed.

[0078] The single rod to be processed is a cylindrical metal piece.

[0079] Exemplarily, the first turning processing is realized by a turning device. Specifically, the first end of the single rod to be processed is clamped on the turning device. The turning device is turned on, and the spindle of the turning device drives the single rod to be processed to rotate. The first turning tool is controlled to cut into the single rod to be processed from the second end of the single rod to be processed, and the first cutting distance of the first turning tool is adjusted to be a first preset length.

[0080] Exemplarily, please refer to Figure 2 , the first turning processing is performed on the single rod to be processed 21 to obtain a first processed single rod 22.

[0081] Step S102: performing second turning processing on the first processed single rod to obtain a second processed single rod, the second turning processing being used to remove excess material on the first processed single rod.

[0082] Exemplarily, the second turning processing is realized by a turning device. Specifically, the first end of the single rod to be processed is clamped on the turning device. The turning device is turned on, and the spindle of the turning device drives the single rod to be processed to rotate. The second turning tool is controlled to cut into the single rod to be processed from the second end of the single rod to be processed, and the second cutting distance of the second turning tool is adjusted to be a second preset length.

[0083] Exemplarily, please refer to Figure 2The first machining single rod 22 is subjected to second turning processing to obtain a second machining single rod 23.

[0084] Step S103: quenching the second machining single rod to obtain an initial quenching single rod.

[0085] The object of quenching is the surface of the second machining single rod.

[0086] Optionally, the temperature of the second machining single rod is heated to above the quenching temperature, and the quenching temperature is the austenitizing temperature. The second machining single rod is cooled using a quenching liquid to achieve quenching of the second machining single rod, thereby obtaining the initial quenching single rod.

[0087] Step S104: obtaining size information of the initial quenching single rod.

[0088] The size information includes at least one of the outer diameter, the length, and the surface roughness of the initial quenching single rod.

[0089] Optionally, a real-time image of the initial quenching single rod is captured. The surface roughness of the initial quenching single rod is extracted from the real-time image.

[0090] Optionally, the surface of the initial quenching single rod is scanned to obtain a scanning result. The outer diameter and the length of the initial quenching single rod are extracted from the scanning result.

[0091] Step S105: according to the size information, the initial quenching single rod is subjected to correction processing to obtain a corrected quenching single rod.

[0092] Due to the characteristics of quenching, the surface condition of the initial quenching single rod is difficult to control, and the size of the partial area of the initial quenching single rod will deviate. After quenching is completed, the initial quenching single rod needs to be subjected to correction processing to ensure the quality of the final single rod.

[0093] Optionally, the correction processing used in the present application is grinding processing.

[0094] Step S106: combining the corrected quenching single rod, the rolling element, and the outer shell to obtain a single rod bearing.

[0095] By adopting the technical scheme, the excess material on the single rod can be accurately and efficiently removed through two turning processes in sequence, laying a good foundation for subsequent processing. Then, the single rod after turning is subjected to quenching treatment, which can significantly improve the hardness and wear resistance of the surface of the single rod, thereby greatly enhancing the overall mechanical strength and load capacity of the finally manufactured single rod bearing and prolonging the service life thereof. After quenching, the size information of the initial quenched single rod is acquired, and targeted correction treatment is performed according to the size information, so that the deformation and size deviation caused by the quenching process can be effectively compensated and corrected, and the size accuracy of the single rod is ensured. Finally, the corrected quenched single rod with the required accuracy is assembled with the rolling element and the shell, so that the assembly accuracy and running stability of the bearing are ensured. The method has a clear process and takes into account the strength improvement and accuracy control, and effectively improves the product quality and performance consistency of the single rod bearing.

[0096] In the following embodiments, due to the characteristics of the quenching treatment, it is difficult to ensure that the surface of the initial quenched single rod after the quenching treatment meets the requirements, and therefore the initial quenched single rod needs to be processed. Embodiments of the present application disclose a correction method for an initial quenched single rod. Referring to Figure 3 , the method comprises:

[0097] Step S301: comparing the size information and the preset standard size to obtain a size difference value and a single rod region corresponding to the size difference value.

[0098] The preset standard size is a standard size of the single rod in the single rod bearing, which is related to the design standard of the single rod bearing.

[0099] The single rod region is the position of the size information corresponding to the size difference value on the initial quenched single rod.

[0100] Optionally, in the case where the size information includes an actual outer diameter and an actual length, the preset standard size includes a standard outer diameter and a standard length. The difference between the actual outer diameter and the standard outer diameter is calculated to obtain an outer diameter difference value. The difference between the actual length and the standard length is calculated to obtain a length difference value. The outer diameter difference value and the length difference value are taken as the size difference value.

[0101] Optionally, in the case where the size information includes a surface roughness, the preset standard size includes a standard roughness. The difference between the surface roughness and the standard roughness is calculated to obtain a roughness difference value. The roughness difference value is taken as the size difference value.

[0102] Step S302: determining a problem size difference value greater than a preset size difference value threshold from the size difference value.

[0103] The preset size difference value threshold is a preset empirical value, and a technician can adjust the specific value of the preset size difference value threshold according to actual requirements, which is not limited in the present application.

[0104] Step S303: determining the problem single-bar region in the initial quenched single bar according to the problem size difference and the single-bar region.

[0105] The problem single-bar region is a position in the single-bar region corresponding to the problem size difference. That is, the size information on the problem single-bar region corresponds to the problem size difference.

[0106] Step S304: performing grinding processing on the problem single-bar region to obtain a corrected quenched single bar.

[0107] For example, the initial quenched single bar is clamped on a grinding device. The grinding device is started. A grinding tool in the grinding device is controlled to be aligned with the problem single-bar region, and the grinding tool is used to perform grinding processing on the problem single-bar region. After the grinding processing on all the problem single-bar regions is completed, the corrected quenched single bar is obtained.

[0108] By using the above technical solution, the size difference and the specific single-bar region corresponding to the size difference can be accurately obtained by comparing the size information of the initial quenched single bar with the preset standard size, and the deviation is located. Further, by setting the preset size difference threshold to screen out the problem size difference exceeding the allowed range, and determining the problem single-bar region according to the problem size difference, the subsequent processing target is clear, unnecessary full-size processing is avoided, and the processing efficiency is improved. Finally, the grinding processing is performed on the identified problem region, the fine and localized correction is realized, the out-of-tolerance parts caused by quenching deformation or other processing errors are effectively corrected to the qualified range, so that the processing efficiency is ensured, and the size precision and the qualified rate of the single bar are significantly improved.

[0109] Embodiments of the present application disclose a grinding processing method. Referring to Figure 4 The method comprises the following steps.

[0110] Step S401: numbering the problem single-bar region in the case that there are at least two problem single-bar regions.

[0111] Optionally, the problem single-bar region is numbered according to the order of the grinding processing on the initial quenched single bar. For example, the grinding processing on the initial quenched single bar is from the first end to the second end, and the problem single-bar region is numbered in the order from the first end to the second end.

[0112] Step S402: obtaining a processing rotation speed.

[0113] The processing rotation speed refers to the rotation speed of the initial quenched single bar along the symmetry axis.

[0114] Step S403: selecting an i-th problem single-bar region and an i+1-th problem single-bar region in the problem single-bar region.

[0115] wherein i is a positive integer greater than 1. The ith problematic single-bar region and the (i+1)th problematic single-bar region are adjacent problematic single-bar regions.

[0116] Step S404: Obtain an axial distance between the ith problematic single-bar region and the (i+1)th problematic single-bar region.

[0117] The axial distance refers to a distance between projection positions of the ith problematic single-bar region and the (i+1)th problematic single-bar region on the sidewall.

[0118] Step S405: Obtain a deviation angle between the ith problematic single-bar region and the (i+1)th problematic single-bar region, the deviation angle representing an angle difference between the ith problematic single-bar region and the (i+1)th problematic single-bar region in the axial direction.

[0119] For example, the ith problematic single-bar region is determined at an ith position on the sidewall of the initial quenched single-bar. The (i+1)th problematic single-bar region is determined at an (i+1)th position on the sidewall of the initial quenched single-bar. A line connecting the ith position and the center of the initial quenched single-bar is taken as an ith connecting line. A line connecting the (i+1)th position and the center of the initial quenched single-bar is taken as an (i+1)th connecting line. An included angle between the ith connecting line and the (i+1)th connecting line in the axial direction is taken as the deviation angle.

[0120] Step S406: Obtain an ith machining moving speed corresponding to the ith problematic single-bar region according to the machining rotating speed, the axial distance, and the deviation angle.

[0121] The method for determining the ith machining moving speed can refer to the embodiment shown in Figure 5 , which will not be described herein again.

[0122] Step S407: Add the ith machining moving speed to a machining moving speed set.

[0123] The machining moving speed set is used for temporarily storing machining moving speeds.

[0124] Step S408: Update i to i+1, and repeat the above five steps until each problematic single-bar region is traversed, to obtain the machining moving speed set, wherein a difference between adjacent machining moving speeds in the machining moving speed set is less than a preset moving speed difference.

[0125] The preset moving speed difference is a preset empirical value. A technician can adjust a specific value of the preset moving speed difference according to actual requirements.

[0126] Step S409: Control the grinding equipment to perform grinding processing according to the machining moving speed set and the machining rotating speed, to obtain a corrected quenched single-bar.

[0127] For example, the movement of the initial quenched single-bar is controlled according to the machining moving speed set, and the rotation of the initial quenched single-bar is adjusted according to the machining rotating speed.

[0128] By adopting the technical scheme, when there are multiple problem areas to be processed, the processing process is orderly through numbering management. By comprehensively considering the processing speed, the axial distance between adjacent problem areas, and the deviation angle in the circumferential direction, a specific processing moving speed for the ith problem area is calculated, and the moving speed change between the continuous processing areas is ensured to be smooth, forming an optimized processing moving speed set. This method can guide the grinding equipment to dynamically adjust the moving speed according to different local geometric characteristics, avoid unstable processing quality or equipment vibration caused by sudden speed change, realize high-speed, smooth and accurate continuous grinding correction, and significantly improve the correction efficiency and surface treatment consistency of complex deviation distribution.

[0129] The embodiment of the application discloses a method for determining a processing moving speed. Referring to Figure 5 The method comprises the following steps:

[0130] Step S501: acquiring an ith-1 processing moving speed corresponding to an ith-1 problem single rod area.

[0131] The ith-1 problem single rod area is the last problem single rod area of the ith problem single rod area.

[0132] The ith-1 processing moving speed is the moving speed of moving the processing point of the grinding equipment from the ith-1 problem single rod area to the ith problem single rod area.

[0133] Step S502: acquiring a recommended processing moving speed interval.

[0134] The recommended processing moving speed interval is a preset empirical value, which can be adjusted by a technician according to actual needs.

[0135] Step S503: generating a deviation angle set according to the deviation angle.

[0136] For example, if the deviation angle is α, the angle in the deviation angle set can be represented as α+360×k, and k is a natural number.

[0137] Step S504: obtaining a predicted moving time set according to the deviation angle set and the processing speed.

[0138] For example, the ratio of the deviation angle to the processing speed is calculated to obtain the predicted moving time by taking any deviation angle in the deviation angle set. The predicted moving time set is obtained by traversing each deviation angle in the deviation angle set.

[0139] Step S505: obtaining a processing moving speed set according to the predicted moving time set and the axial distance.

[0140] For example, taking any one of the set of predicted moving time lengths, a ratio of the axial distance to the predicted moving time length is calculated to obtain the processing moving speed. Each of the set of predicted moving time lengths is traversed to obtain a set of processing moving speeds.

[0141] Step S506: determining the i th processing moving speed in the set of processing moving speeds, so that the i th processing moving speed falls into the recommended processing moving speed interval, and the difference between the i th processing moving speed and the i-1 th processing moving speed is less than the preset moving speed difference value.

[0142] By adopting the above technical solution, the determination strategy of the processing moving speed is further refined. By referring to the processing moving speed of the previous problem area and combining the recommended processing moving speed interval, the coherence and rationality of the processing parameter setting are ensured. Based on the set of deviation angles and the processing rotating speed, the predicted moving time length is calculated, and then the set of processing moving speeds is calculated according to the axial distance. This process is based on the systematic calculation of multiple parameters, so that the i th processing moving speed determined finally not only meets the processing requirements of the current area, but also smoothly connects with the processing moving speed of the previous area. This method effectively reduces the speed fluctuation in the processing process, ensures the motion stability of the grinding equipment during the transition between different problem areas, and thus improves the overall quality consistency of the processed surface.

[0143] The embodiment of the application discloses a rotating speed adjustment method of a grinding equipment. Referring to Figure 6 , the method comprises:

[0144] Step S601: if the i th processing moving speed is not determined in the set of processing moving speeds, then a candidate processing moving speed closest to the recommended processing moving speed interval is determined in the set of processing moving speeds.

[0145] For example, the distance of each processing moving speed in the set of processing moving speeds to the recommended processing moving speed interval is calculated. The processing moving speed corresponding to the minimum value in the distance is taken as the candidate processing moving speed.

[0146] Step S602: generating a set of candidate processing rotating speeds according to the candidate processing moving speed and the set of deviation angles.

[0147] For example, taking any one of the set of deviation angles, a ratio of the deviation angle to the predicted moving time length is calculated to obtain the candidate processing moving speed. Each of the set of deviation angles is traversed to obtain the set of candidate processing moving speeds.

[0148] Step S603: determining a target rotating speed in the set of processing rotating speeds, which has the minimum difference from the processing rotating speed.

[0149] The target rotating speed is the rotating speed in the set of processing rotating speeds, which has the minimum difference from the processing rotating speed.

[0150] Step S604: In the case that the grinding device is close to the i-th problem single-bar region, the rotating speed of the grinding device is adjusted to the target rotating speed.

[0151] For example, in the case that the distance between the grinding tool in the grinding device and the i-th problem single-bar region is less than the preset distance threshold, it is determined that the grinding device is close to the i-th problem single-bar region.

[0152] By using the above technical solution, when the ideal value that meets the recommended moving speed interval and ensures smooth transition of the moving speed cannot be calculated, the method first selects the candidate machining moving speed closest to the recommended interval. Then, the possible candidate machining rotating speed set is deduced reversely through the candidate moving speed and the deviation angle set, and the target rotating speed closest to the current set machining rotating speed is selected from the candidate machining rotating speed set. Finally, when the grinding device is about to machine the problem region, the rotating speed of the device is dynamically adjusted instead of the moving speed. This flexible and adaptive strategy ensures that even in the case of limited calculation, the best machining condition can be approached by optimizing another key parameter, thereby guaranteeing the grinding correction effect of the problem region and improving the robustness and adaptability of the method.

[0153] Embodiments of the present application disclose a machining adjustment method for an initial quenched single bar. Please refer to Figure 7 The method comprises the following steps:

[0154] Step S701: Obtain a machining influence region corresponding to a problem single-bar region on an initial quenched single bar.

[0155] For example, after the problem single-bar region is determined, a machining influence region is determined on the initial quenched single bar and the problem single-bar region is located, thereby obtaining the machining influence region.

[0156] Step S702: According to a preset standard size, determine whether there is an over-influenced region in the machining influence region, and the quenching layer thickness of the over-influenced region is less than a preset minimum size.

[0157] Optionally, the quenching layer thickness of each region in the machining influence region is obtained. If the quenching layer thickness of a region is less than the preset minimum size, it is determined that there is an over-influenced region.

[0158] In some other embodiments, a surface image of the initial quenched single bar is obtained. According to the surface image, it is determined whether there is a quenching layer at each region of the initial quenched single bar. If there is a quenching layer at each region, it is considered that there is no over-influenced region in the machining influence region. If there is no quenching layer at at least one region, it is considered that there is an over-influenced region in the machining influence region.

[0159] Step S703: If yes, obtain the maximum length and the covering angle of the problem single-bar region along the axial direction.

[0160] In some other embodiments, if no, the original process remains unchanged.

[0161] Step S704: generating an adjustment length according to the machining rotation speed, the maximum length, and the coverage angle.

[0162] Optionally, in a preset mapping table, the adjustment length is determined according to the machining rotation speed, the maximum length, and the coverage angle. The mapping table records the mapping relationship among the machining rotation speed, the maximum length, the coverage angle, and the adjustment length.

[0163] Step S705: controlling the grinding equipment to adjust the initial quenched single rod to reciprocate according to the adjustment length.

[0164] For example, the initial quenched single rod is controlled to move according to the adjustment length, so that the moving length of the initial quenched single rod in the first direction is the adjustment length, and the moving length of the initial quenched single rod in the second direction is the adjustment length. The first direction and the second direction are opposite directions.

[0165] By using the above technical solution, the size too small area possibly generated around the correction area due to excessive grinding is identified, the characteristic parameters of the original problem area are obtained, and the optimized grinding adjustment length is calculated in combination with the machining rotation speed. Accordingly, the grinding equipment is controlled to reciprocate by the corresponding length, which can compensate for the potential excessive grinding area or perform finishing processing, effectively eliminates the hidden danger of local stress concentration or size unqualification, ensures the size uniformity and geometric integrity of the entire single rod shaft, and further improves the reliability and safety of the final product.

[0166] Embodiments of the present application disclose a correction processing method of an initial quenched single rod. Referring to Figure 8 The method comprises the following steps.

[0167] Step S801: obtaining a machining image of a corrected quenched single rod.

[0168] The machining image is an image of the surface of the corrected quenched single rod.

[0169] Step S802: obtaining a correction condition of the corrected quenched single rod through the machining image.

[0170] The correction condition is used to represent the size of the surface of the corrected quenched single rod. The correction condition comprises at least one of the outer diameter, the length, and the surface roughness of the corrected quenched single rod.

[0171] Step S803: if the correction condition does not conform to a preset standard size, determining a correction area on the corrected quenched single rod according to the correction condition.

[0172] The correction area refers to an area where the correction condition does not conform to the correction standard.

[0173] Optionally, in the case that the modification condition includes the actual outer diameter and the actual length, the preset standard size includes a standard outer diameter and a standard length. A difference between the actual outer diameter and the standard outer diameter is calculated to obtain an outer diameter difference. A difference between the actual length and the standard length is calculated to obtain a length difference. The outer diameter difference and the length difference are taken as the size difference. Problem size differences greater than a preset size difference threshold are determined from the size difference, and a region corresponding to the aforementioned problem size difference is determined to obtain a modification region.

[0174] Optionally, in the case that the modification condition includes the surface roughness, the preset standard size includes a standard roughness. A difference between the surface roughness and the standard roughness is calculated to obtain a roughness difference. The roughness difference is taken as the size difference. Problem size differences greater than a preset size difference threshold are determined from the size difference, and a region corresponding to the aforementioned problem size difference is determined to obtain a modification region.

[0175] Step S804: According to the modification region, the modification processing of the initial quenched single rod is adjusted.

[0176] For example, after the modification region is determined, the modification processing of the initial quenched single rod is adjusted according to the position of the modification region, so that the modification processing can be performed on the modification region.

[0177] By using the above technical solution, the modification processing effect of the previous modification processing can be inspected and evaluated in real time by acquiring the processing image of the modified quenched single rod and analyzing the modification condition thereof. If it is found that the modification result does not reach the preset standard, the modification region that needs to be processed again can be accurately positioned according to the image analysis result, and the subsequent modification processing parameters or strategies are adjusted according to the feedback information. This closed-loop quality control method based on visual detection can timely find and correct the deviation, realizes self-optimization and adjustment of the manufacturing process, significantly reduces the scrap rate, and ensures the consistency and high quality of the single rod bearing manufacturing.

[0180] The memory 902 is configured to store a program of the single rod bearing manufacturing method.

[0181] The processor 903 can load and execute the program in the memory, and implement the single rod bearing manufacturing method.

[0182] By adopting the technical scheme, the excess material on the single rod can be accurately and efficiently removed through two turning processes in sequence, laying a good foundation for subsequent processing. Then, the single rod after turning is subjected to quenching treatment, which can significantly improve the hardness and wear resistance of the surface of the single rod, thereby greatly enhancing the overall mechanical strength and load capacity of the finally manufactured single rod bearing and prolonging the service life thereof. After quenching, the deformation and size deviation possibly caused by the quenching process can be effectively compensated and corrected by acquiring the size information of the initial quenched single rod and performing targeted correction treatment accordingly, so as to ensure the size precision of the single rod. Finally, the corrected quenched single rod with the required precision is assembled with the rolling element and the shell, so as to ensure the assembly precision and running stability of the bearing. The method has clear process flow and takes into account the strength improvement and precision control, and effectively improves the product quality and performance consistency of the single rod bearing.
