Description

Technical Field

[0001] This application relates to the field of bearing manufacturing technology, and in particular to a manufacturing method, system, smart terminal, and storage medium for a single-bar bearing. Background Technology

[0002] A bearing is a mechanical component whose core function is to reduce frictional resistance between moving parts and to support rotating components. A single-rod bearing is a common type of bearing, consisting of a single rod, rolling elements, and a housing.

[0003] In the manufacturing of single-rod bearings, the single rod is prioritized. The raw material is turned and ground to obtain the single rod. The single rod, rolling elements, and housing are then assembled to form the single-rod bearing.

[0004] Regarding the aforementioned technologies, the strength of a single rod itself is relatively limited, which leads to a decrease in the overall strength of the single rod bearing. Summary of the Invention

[0005] To improve the overall strength of a single-bar bearing, this application provides a manufacturing method, system, smart terminal, and storage medium for a single-bar bearing.

[0006] In a first aspect, this application provides a method for manufacturing a single-bar bearing, employing the following technical solution: A method for manufacturing a single-bar bearing, comprising: The single bar to be processed is subjected to a first turning process to obtain a first processed single bar. The first turning process is used to remove the excess material on the single bar to be processed. The first machining rod is subjected to a second turning process to obtain a second machining rod. The second turning process is used to remove the excess material on the first machining rod. The second processed rod is subjected to quenching treatment to obtain an initial quenched rod; Obtain the dimensional information of the initially quenched single rod; Based on the dimensional information, the initial quenched rod is corrected to obtain a corrected quenched rod; The modified quenched rod, rolling element, and housing are combined to obtain a single-rod bearing.

[0007] By employing the above technical solution, two sequential turning operations can precisely and efficiently remove excess material from the single rod, laying a solid foundation for subsequent processing. The turned single rod is then quenched, a step that significantly improves the surface hardness and wear resistance, thereby greatly enhancing the overall mechanical strength and load-bearing capacity of the final single-rod bearing and extending its service life. After quenching, by obtaining the initial dimensional information of the quenched single rod and performing targeted corrections, deformation and dimensional deviations that may occur during the quenching process can be effectively compensated and corrected, ensuring the dimensional accuracy of the single rod. Finally, the corrected and quenched single rod, meeting the required accuracy, is assembled with the rolling elements and the housing, ensuring the bearing's assembly accuracy and stable operation. This method has a clear process, balancing strength improvement and precision control, effectively improving the product quality and performance consistency of single-rod bearings.

[0008] Optionally, the size information is compared with a preset standard size to obtain the size difference and the single rod area corresponding to the size difference; Determine the problematic size difference that is greater than a preset size difference threshold from the size differences; Based on the problem size difference and the single rod region, the problem single rod region in the initial quenched single rod is determined; The problematic single rod area is ground to obtain the corrected quenched single rod.

[0009] By employing the above technical solution, the dimensional information of the initial quenched single rod is compared with the preset standard dimensions to accurately obtain the dimensional difference and its corresponding specific single rod area, thus achieving the location of the deviation. Furthermore, by setting a preset dimensional difference threshold, problematic dimensional differences exceeding the allowable range are filtered out, and the problematic single rod area is determined accordingly. This makes the subsequent processing target clear, avoids unnecessary full-size machining, and improves processing efficiency. Finally, grinding is performed on the identified problematic areas, achieving refined and localized correction. This effectively corrects out-of-tolerance areas caused by quenching deformation or other processing errors to the acceptable range, thereby significantly improving the dimensional accuracy and pass rate of the single rod while ensuring processing efficiency.

[0010] Optionally, if there are at least two problematic single-pole areas, the problematic single-pole areas shall be numbered; Obtain the machining speed; The selection step includes: selecting the i-th problem pole region and the (i+1)-th problem pole region among the problem pole regions; Perform the first acquisition step, which includes: acquiring the axial distance from the i-th problem pole region to the (i+1)-th problem pole region; Perform a second acquisition step, which includes: acquiring the deviation angle between the i-th problem single rod region and the (i+1)-th problem single rod region, wherein the deviation angle represents the angular difference between the i-th problem single rod region and the (i+1)-th problem single rod region in the axial direction; The calculation step includes obtaining the i-th machining speed corresponding to the i-th problem single-bar region based on the machining speed, the axial distance, and the deviation angle. The update step includes: adding the i-th processing speed to the processing speed set; The step of updating i to i+1 is repeated, along with the selection step, the first acquisition step, the second acquisition step, the calculation step, and the update step, until all problem single-bar regions are traversed to obtain the processing speed set, wherein the difference between adjacent processing speeds in the processing speed set is less than a preset speed difference. According to the processing speed set and the processing speed, the grinding equipment is controlled to perform grinding to obtain the modified quenched single rod.

[0011] By adopting the above technical solution, the orderly processing of multiple problem areas is achieved through numbered management. By comprehensively considering the machining speed, the axial distance between adjacent problem areas, and their circumferential deviation angle, a specific machining speed for the i-th problem area is calculated, ensuring smooth speed changes between consecutive machining areas, thus forming an optimized set of machining speeds. This method guides the grinding equipment to dynamically adjust its movement speed according to different local geometric features, avoiding unstable machining quality or equipment vibration caused by sudden speed changes. It achieves high-speed, stable, and precise continuous grinding correction, significantly improving the correction efficiency for complex deviation distributions and surface treatment consistency.

[0012] Optionally, obtain the (i-1)th processing speed corresponding to the (i-1)th problem single-bar region; Obtain the recommended processing speed range; Generate a set of deviation angles based on the deviation angles; Based on the set of deviation angles and the machining speed, the set of expected travel times is obtained; Based on the expected movement time set and the axial distance, the processing speed set is obtained; The i-th processing speed is determined from the set of processing speeds, such that the i-th processing speed falls within the recommended processing speed range, and the difference between the i-th processing speed and the (i-1)-th processing speed is less than the preset speed difference.

[0013] By adopting the above technical solution, the strategy for determining the machining speed was further refined. By referencing the machining speed of the previous problem area and combining it with the recommended machining speed range, the consistency and rationality of the machining parameter settings were ensured. Based on the deviation angle, a set was generated, and the expected movement time was calculated in conjunction with the machining speed. Then, the machining speed set was solved based on the axial distance. This process, based on a systematic calculation of multiple parameters, ensures that the final determined i-th machining speed not only meets the machining requirements of the current area but also smoothly connects with the machining speed of the previous area. This method effectively reduces speed fluctuations during machining, ensures the smooth movement of the grinding equipment when transitioning between different problem areas, and thus improves the overall quality consistency of the machined surface.

[0014] Optionally, if the i-th machining speed is not determined in the set of machining speeds, then a candidate machining speed that is closest to the recommended machining speed range is determined in the set of machining speeds. Based on the candidate machining speed and the set of deviation angles, a set of candidate machining speeds is generated; Determine the target rotational speed with the smallest difference from the set of machining rotational speeds; When the grinding equipment is close to the i-th problem bar region, the rotational speed of the grinding equipment is adjusted to the target rotational speed.

[0015] By employing the above technical solution, when an ideal value that both conforms to the recommended speed range and ensures a smooth speed transition cannot be calculated, this method first selects the candidate machining speed closest to the recommended range. Subsequently, it uses this candidate speed and the set of deviation angles to deduce a set of possible candidate machining speeds, and selects the target speed closest to the currently set machining speed. Finally, when the grinding equipment is about to process the problem area, the equipment speed, rather than the moving speed, is dynamically adjusted. This flexible adaptive strategy ensures that even under computational constraints, the optimal machining conditions can be approached by optimizing another key parameter, guaranteeing the grinding correction effect in the problem area and improving the robustness and adaptability of the method.

[0016] Optionally, the machining influence area corresponding to the problematic single rod region on the initially quenched single rod is obtained; Based on the preset standard size, it is determined whether there is an excessive influence area within the processing influence area, and the quenching layer thickness of the excessive influence area is less than the minimum value of the preset size; If so, then obtain the maximum length and coverage angle of the single pole region along the axial direction; The adjustment length is generated based on the processing speed, the maximum length, and the coverage angle; The grinding equipment is controlled to reciprocate according to the adjusted length, and the initial quenching rod is adjusted to perform reciprocating motion.

[0017] By adopting the above technical solution, areas around the correction zone that may be undersized due to over-grinding are identified, and the characteristic parameters of the original problem area are obtained. Combined with the machining speed, an optimized grinding adjustment length is calculated. Based on this, the grinding equipment is controlled to perform reciprocating motion of the corresponding length. This operation can compensate for or finish potentially over-grinded areas, effectively eliminating the hidden dangers of localized stress concentration or dimensional inconsistencies, ensuring the dimensional uniformity and geometric integrity of the entire single-shaft, and further improving the reliability and safety of the final product.

[0018] Optionally, obtain the machining image of the modified quenched single rod; The correction status of the modified quenched single rod is obtained through the processing image; If the correction does not conform to the preset standard size, then a correction area is determined on the correction-quenched single rod according to the correction condition; Based on the correction area, adjust the correction process for the initial quenched rod.

[0019] By adopting the above technical solution, and by acquiring and analyzing the machining images of the corrected quenched single rod, the effectiveness of previous correction processes can be inspected and evaluated in real time. If the correction results are found to be below the preset standard, the correction area requiring further processing can be accurately located based on the image analysis results, and subsequent correction processing parameters or strategies can be adjusted accordingly. This closed-loop quality control method based on vision inspection can promptly detect and correct deviations, achieving self-optimization and adjustment of the manufacturing process, significantly reducing the scrap rate, and ensuring the consistency and high quality of single rod bearing manufacturing.

[0020] Secondly, this application provides a manufacturing system for a single-bar bearing, employing the following technical solution: A manufacturing system for a single-bar bearing, comprising: The acquisition module is used to obtain size information; A memory for storing the program for manufacturing the single-bar bearing; The processor and the program in the memory can be loaded and executed by the processor to implement the manufacturing method of the single rod bearing.

[0021] By employing the above technical solution, two sequential turning operations can precisely and efficiently remove excess material from the single rod, laying a solid foundation for subsequent processing. The turned single rod is then quenched, a step that significantly improves the surface hardness and wear resistance, thereby greatly enhancing the overall mechanical strength and load-bearing capacity of the final single-rod bearing and extending its service life. After quenching, by obtaining the initial dimensional information of the quenched single rod and performing targeted corrections, deformation and dimensional deviations that may occur during the quenching process can be effectively compensated and corrected, ensuring the dimensional accuracy of the single rod. Finally, the corrected and quenched single rod, meeting the required accuracy, is assembled with the rolling elements and the housing, ensuring the bearing's assembly accuracy and stable operation. This method has a clear process, balancing strength improvement and precision control, effectively improving the product quality and performance consistency of single-rod bearings.

[0022] Thirdly, this application provides a smart terminal, which adopts the following technical solution: A smart terminal includes a memory and a processor, wherein the memory stores a computer program that can be loaded by the processor and execute the method described in any one of the above.

[0023] Fourthly, this application provides a computer storage medium capable of storing corresponding programs, which facilitates improving the overall strength of a single-bar bearing, and adopts the following technical solution: A computer-readable storage medium storing a computer program capable of being loaded by a processor and executing any of the above-described methods for manufacturing a single-bar bearing.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. By performing two consecutive turning operations, excess material on the single rod can be removed accurately and efficiently, laying a good foundation for subsequent processing. The turned single rod is then quenched, a step that significantly improves the surface hardness and wear resistance, thereby greatly enhancing the overall mechanical strength and load-bearing capacity of the final single-rod bearing and extending its service life. After quenching, by obtaining the initial dimensional information of the quenched single rod and performing targeted correction processing, deformation and dimensional deviations that may be caused during the quenching process can be effectively compensated and corrected, ensuring the dimensional accuracy of the single rod. Finally, the corrected and quenched single rod, meeting the required accuracy, is assembled with the rolling elements and the housing, ensuring the assembly accuracy and stable operation of the bearing. This method has a clear process, balances strength improvement and precision control, and effectively improves the product quality and performance consistency of the single-rod bearing. 2. By comparing the initial dimensional information of the quenched single rod with the preset standard dimensions, the dimensional difference and its corresponding specific area can be accurately obtained, thus achieving the location of the deviation. Furthermore, by setting a preset dimensional difference threshold, problematic dimensional differences exceeding the allowable range are filtered out, and the problematic single rod area is determined accordingly. This makes the subsequent processing target clear, avoids unnecessary full-size machining, and improves processing efficiency. Finally, grinding is performed on the identified problematic areas, achieving refined and localized correction. This effectively corrects out-of-tolerance areas caused by quenching deformation or other processing errors to the acceptable range, thereby significantly improving the dimensional accuracy and pass rate of the single rod while ensuring processing efficiency.

[0034] To make the purpose, technical solution, and advantages of this application clearer, the following description is provided in conjunction with the appendix. Figure 1 To be continued Figure 9The present application will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the application.

[0035] This application discloses a method for manufacturing a single-bar bearing. (Refer to...) Figure 1 The method includes: Step S101: Perform a first turning operation on the single rod to be machined to obtain a first machined single rod. The first turning operation is used to remove excess material from the single rod to be machined.

[0036] The metal part to be processed is a cylindrical rod.

[0037] For example, the first turning operation is performed using a turning machine. Specifically, the first end of the single rod to be processed is clamped on the turning machine. The turning machine is turned on, causing the spindle on the turning machine to rotate the single rod to be processed. The first turning tool is controlled to cut into the single rod to be processed from the second end, and the first cutting distance of the first turning tool is adjusted to a first preset length.

[0038] For example, please refer to Figure 2 The single rod 21 to be machined is subjected to the first turning process to obtain the first machined single rod 22.

[0039] Step S102: Perform a second turning operation on the first machining bar to obtain a second machining bar. The second turning operation is used to remove the excess material on the first machining bar.

[0040] For example, the second turning operation is performed using a turning machine. Specifically, the first end of the single rod to be processed is clamped on the turning machine. The turning machine is turned on, causing the spindle on the turning machine to rotate the single rod to be processed. The second turning tool is controlled to cut into the single rod from the second end of the single rod to be processed, and the second cutting distance of the second turning tool is adjusted to a second preset length.

[0041] For example, please refer to Figure 2 The first machining rod 22 is then subjected to a second turning process to obtain the second machining rod 23.

[0042] Step S103: Quench the second machining rod to obtain the initial quenched rod.

[0043] The object subjected to quenching treatment is the surface of the second machining rod.

[0044] Optionally, the temperature of the second machining rod is heated to above the quenching temperature, which is the austenitizing temperature. The second machining rod is then cooled with a quenching fluid to achieve the quenching treatment, thereby obtaining the initially quenched rod.

[0045] Step S104: Obtain the dimensional information of the initial quenched single rod.

[0046] The dimensional information includes at least one of the following: the outer diameter, length, and surface roughness of the initially quenched bar.

[0047] Optionally, capture real-time images of the initially quenched bar. Extract the surface roughness of the initially quenched bar from the real-time images.

[0048] Optionally, the surface of the initially quenched rod is scanned to obtain the scan results. The outer diameter and length of the initially quenched rod are then extracted from the scan results.

[0049] Step S105: Based on the dimensional information, the initial quenched rod is corrected to obtain the corrected quenched rod.

[0050] Due to the characteristics of quenching, the surface condition of the initially quenched rod is difficult to control, and certain dimensional deviations may occur in some areas of the initially quenched rod. Therefore, after quenching, the initially quenched rod needs to be corrected to ensure the quality of the final rod.

[0051] Optionally, the correction process used in this application is grinding.

[0052] Step S106: Combine the modified quenched single rod, rolling element and housing to obtain single rod bearing.

[0053] By employing the above technical solution, two sequential turning operations can precisely and efficiently remove excess material from the single rod, laying a solid foundation for subsequent processing. The turned single rod is then quenched, a step that significantly improves the surface hardness and wear resistance, thereby greatly enhancing the overall mechanical strength and load-bearing capacity of the final single-rod bearing and extending its service life. After quenching, by obtaining the initial dimensional information of the quenched single rod and performing targeted corrections, deformation and dimensional deviations that may occur during the quenching process can be effectively compensated and corrected, ensuring the dimensional accuracy of the single rod. Finally, the corrected and quenched single rod, meeting the required accuracy, is assembled with the rolling elements and the housing, ensuring the bearing's assembly accuracy and stable operation. This method has a clear process, balancing strength improvement and precision control, effectively improving the product quality and performance consistency of single-rod bearings.

[0054] In the following embodiments, due to the characteristics of quenching, it is difficult to guarantee that the surface of the initially quenched single rod meets the requirements. Therefore, it is necessary to process the initially quenched single rod. This application discloses a method for correcting the initially quenched single rod. (Refer to...) Figure 3 The method includes: Step S301: Compare the size information with the preset standard size to obtain the size difference and the single rod area corresponding to the size difference.

[0055] The preset standard dimensions are the standard dimensions of a single rod in a single-rod bearing, which are related to the design standards of the single-rod bearing.

[0056] The single-bar region represents the position of the dimensional information corresponding to the dimensional difference on the initially quenched single-bar.

[0057] Optionally, if the dimensional information includes the actual outer diameter and actual length, the preset standard dimensions include the standard outer diameter and standard length. The difference between the actual outer diameter and the standard outer diameter is calculated to obtain the outer diameter difference. The difference between the actual length and the standard length is calculated to obtain the length difference. The outer diameter difference and the length difference are used as the dimensional difference.

[0058] Optionally, if the dimensional information includes surface roughness, the preset standard dimension includes the standard roughness. The difference between the surface roughness and the standard roughness is calculated to obtain the roughness difference. This roughness difference is then used as the dimensional difference.

[0059] Step S302: Determine the problematic size difference that is greater than the preset size difference threshold from the size difference values.

[0060] The preset size difference threshold is a preset empirical value. Technicians can adjust the specific value of the preset size difference threshold according to actual needs. This application does not make specific limitations on this.

[0061] Step S303: Determine the problem bar region in the initial quenched bar based on the problem size difference and the bar region.

[0062] The problem pole region is the location within the pole region that corresponds to the problem size difference. In other words, the size information in the problem pole region corresponds to the problem size difference.

[0063] Step S304: Grind the problematic single bar area to obtain a corrected quenched single bar.

[0064] For example, the initial hardened bar is clamped on a grinding machine. The grinding machine is turned on. The grinding tool in the grinding machine is aligned with the problem bar area, and the grinding tool grinds the problem bar area. After grinding all the problem bar areas, the corrected hardened bar is obtained.

[0065] By employing the above technical solution, the dimensional information of the initial quenched single rod is compared with the preset standard dimensions to accurately obtain the dimensional difference and its corresponding specific single rod area, thus achieving the location of the deviation. Furthermore, by setting a preset dimensional difference threshold, problematic dimensional differences exceeding the allowable range are filtered out, and the problematic single rod area is determined accordingly. This makes the subsequent processing target clear, avoids unnecessary full-size machining, and improves processing efficiency. Finally, grinding is performed on the identified problematic areas, achieving refined and localized correction. This effectively corrects out-of-tolerance areas caused by quenching deformation or other processing errors to the acceptable range, thereby significantly improving the dimensional accuracy and pass rate of the single rod while ensuring processing efficiency.

[0066] This application discloses a grinding process method. (Refer to...) Figure 4 The method includes: Step S401: If there are at least two problematic single-pole areas, number the problematic single-pole areas.

[0067] Optionally, the problem bar regions can be numbered according to the order in which the initial quenched bar was ground. For example, if the grinding process of the initial quenched bar proceeds from the first end to the second end, then the problem bar regions can be numbered in the order from the first end to the second end.

[0068] Step S402: Obtain the machining speed.

[0069] The machining speed refers to the rotational speed of the initially quenched rod along the axis of symmetry.

[0070] Step S403: Select the i-th and (i+1)-th problem single pole regions in the problem single pole region.

[0071] Where i is a positive integer greater than 1. The i-th problem pole region and the (i+1)-th problem pole region are adjacent problem pole regions.

[0072] Step S404: Obtain the axial distance from the i-th problem pole region to the (i+1)-th problem pole region.

[0073] Axial distance refers to the distance between the projected positions of the i-th problem pole region and the (i+1)-th problem pole region on the side wall.

[0074] Step S405: Obtain the deviation angle between the i-th problem single rod region and the (i+1)-th problem single rod region. The deviation angle represents the angular difference between the i-th problem single rod region and the (i+1)-th problem single rod region in the axial direction.

[0075] For example, the i-th problematic single-bar region is located at the i-th position on the side wall of the initially quenched single-bar. The (i+1)-th problematic single-bar region is located at the (i+1)-th position on the side wall of the initially quenched single-bar. A line is drawn connecting the i-th position and the center of the circle of the initially quenched single-bar, resulting in the i-th connecting line. A line is drawn connecting the (i+1)-th position and the center of the circle of the initially quenched single-bar, resulting in the (i+1)-th connecting line. The angle between the i-th connecting line and the (i+1)-th connecting line in the axial direction is obtained as the deviation angle.

[0076] Step S406: Based on the machining speed, axial distance, and deviation angle, obtain the i-th machining movement speed corresponding to the i-th problem single rod region.

[0077] The method for determining the i-th machining speed can be referred to Figure 5 The embodiments shown are not described in detail here.

[0078] Step S407: Add the i-th machining speed to the machining speed set.

[0079] The processing speed set is used to temporarily store processing speeds.

[0080] Step S408: Update i to i+1, repeat the above five steps until all problem single rod regions are traversed to obtain the processing speed set, wherein the difference between adjacent processing speeds in the processing speed set is less than the preset speed difference.

[0081] The preset speed difference value is a pre-defined empirical value. Technicians can adjust the specific value of the preset speed difference value according to actual needs.

[0082] Step S409: According to the processing speed set and processing speed, control the grinding equipment to perform grinding treatment to obtain the corrected quenched single rod.

[0083] For example, the movement of the initial quenching rod is controlled according to the processing speed set, and the rotation of the initial quenching rod is adjusted according to the processing speed.

[0084] By adopting the above technical solution, the orderly processing of multiple problem areas is achieved through numbered management. By comprehensively considering the machining speed, the axial distance between adjacent problem areas, and their circumferential deviation angle, a specific machining speed for the i-th problem area is calculated, ensuring smooth speed changes between consecutive machining areas, thus forming an optimized set of machining speeds. This method guides the grinding equipment to dynamically adjust its movement speed according to different local geometric features, avoiding unstable machining quality or equipment vibration caused by sudden speed changes. It achieves high-speed, stable, and precise continuous grinding correction, significantly improving the correction efficiency for complex deviation distributions and surface treatment consistency.

[0085] This application discloses a method for determining machining speed. (Refer to...) Figure 5 The method includes: Step S501: Obtain the (i-1)th processing speed corresponding to the (i-1)th problem single rod area.

[0086] The (i-1)th problem pole region is the problem pole region preceding the ith problem pole region.

[0087] The (i-1)th machining speed is the speed at which the machining point of the grinding equipment is moved from the (i-1)th problem single-bar region to the ith problem single-bar region.

[0088] Step S502: Obtain the recommended processing speed range.

[0089] The recommended processing speed range is a preset empirical value, which can be adjusted by technicians according to actual needs.

[0090] Step S503: Generate a set of deviation angles based on the deviation angles.

[0091] For example, if the deviation angle is α, then the angles in the set of deviation angles can be expressed as α + 360 × k, where k is a natural number.

[0092] Step S504: Obtain the set of expected travel times based on the set of deviation angles and the machining speed.

[0093] For example, take any deviation angle from the set of deviation angles, calculate the ratio of the deviation angle to the machining speed, and obtain the expected travel time. Iterate through each deviation angle in the set of deviation angles to obtain the set of expected travel times.

[0094] Step S505: Obtain the machining speed set based on the expected movement time set and axial distance.

[0095] For example, take any expected movement time from the set of expected movement times, calculate the ratio of axial distance to the expected movement time, and obtain the machining speed. Iterate through each expected movement time in the set of expected movement times to obtain the set of machining speeds.

[0096] Step S506: Determine the i-th machining speed from the set of machining speeds, so that the i-th machining speed falls within the recommended machining speed range, and the difference between the i-th machining speed and the (i-1)-th machining speed is less than the preset speed difference.

[0097] By adopting the above technical solution, the strategy for determining the machining speed was further refined. By referencing the machining speed of the previous problem area and combining it with the recommended machining speed range, the consistency and rationality of the machining parameter settings were ensured. Based on the deviation angle, a set was generated, and the expected movement time was calculated in conjunction with the machining speed. Then, the machining speed set was solved based on the axial distance. This process, based on a systematic calculation of multiple parameters, ensures that the final determined i-th machining speed not only meets the machining requirements of the current area but also smoothly connects with the machining speed of the previous area. This method effectively reduces speed fluctuations during machining, ensures the smooth movement of the grinding equipment when transitioning between different problem areas, and thus improves the overall quality consistency of the machined surface.

[0098] This application discloses a method for adjusting the rotational speed of a grinding machine. (Refer to...) Figure 6 The method includes: Step S601: If the i-th machining speed is not determined in the machining speed set, then determine the candidate machining speed that is closest to the recommended machining speed range in the machining speed set.

[0099] For example, the distance from each machining speed in the set of machining speeds to the recommended machining speed range is calculated. The machining speed corresponding to the minimum distance is selected as the candidate machining speed.

[0100] Step S602: Generate a set of candidate machining speeds based on the set of candidate machining movement speeds and deviation angles.

[0101] For example, take any deviation angle from the set of deviation angles, calculate the ratio of the deviation angle to the expected movement time, and obtain the candidate processing speed. Iterate through each deviation angle in the set of deviation angles to obtain the set of candidate processing speeds.

[0102] Step S603: Determine the target speed with the smallest difference from the machining speed in the set of machining speeds.

[0103] The target speed is the speed with the smallest difference from the machining speed in the set of machining speeds.

[0104] Step S604: When the grinding equipment is close to the i-th problem bar area, adjust the rotation speed of the grinding equipment to the target rotation speed.

[0105] For example, when the distance between the grinding tool in the grinding equipment and the i-th problem bar region is less than a preset distance threshold, it is determined that the grinding equipment is close to the i-th problem bar region.

[0106] By employing the above technical solution, when an ideal value that both conforms to the recommended speed range and ensures a smooth speed transition cannot be calculated, this method first selects the candidate machining speed closest to the recommended range. Subsequently, it uses this candidate speed and the set of deviation angles to deduce a set of possible candidate machining speeds, and selects the target speed closest to the currently set machining speed. Finally, when the grinding equipment is about to process the problem area, the equipment speed, rather than the moving speed, is dynamically adjusted. This flexible adaptive strategy ensures that even under computational constraints, the optimal machining conditions can be approached by optimizing another key parameter, guaranteeing the grinding correction effect in the problem area and improving the robustness and adaptability of the method.

[0107] This application discloses a method for adjusting the machining of a single rod after initial quenching. Please refer to... Figure 7 The method includes: Step S701: Obtain the machining influence area corresponding to the problem bar region on the initially quenched bar.

[0108] For example, after identifying the problematic single bar region, the processing-affected region is determined on the initially quenched single bar.

[0109] Step S702: Based on the preset standard dimensions, determine whether there is an excessive influence area within the processing influence area. The quenching layer thickness of the excessive influence area is less than the minimum value of the preset dimensions.

[0110] Optionally, the thickness of the quenched layer at various points within the processing influence area can be obtained. If the quenched layer thickness in any area is less than a preset minimum value, then an over-influence area is identified.

[0111] In some other embodiments, a surface image of the initially quenched single rod is acquired. Based on the surface image, it is determined whether a quenched layer exists throughout the initially quenched single rod. If it exists throughout, it is considered that there is no over-influenced region within the processing influence area. If at least one area lacks a quenched layer, it is considered that there is an over-influenced region within the processing influence area.

[0112] Step S703: If yes, then obtain the maximum length and coverage angle of the problem single pole area along the axial direction.

[0113] In some other embodiments, if not, the original process remains unchanged.

[0114] Step S704: Generate the adjustment length based on the machining speed, maximum length, and coverage angle.

[0115] Optionally, the adjustment length can be determined from a preset mapping table based on the machining speed, maximum length, and coverage angle. The mapping table records the mapping relationship between the machining speed, maximum length, coverage angle, and adjustment length.

[0116] Step S705: Control the grinding equipment to reciprocate according to the adjusted length and the initial quenching rod.

[0117] For example, the initial quenching rod is controlled to move according to an adjustment length, such that the movement length of the initial quenching rod in the first direction is the adjustment length, and the movement length in the second direction is the adjustment length. The first direction and the second direction are opposite directions.

[0118] By adopting the above technical solution, areas around the correction zone that may be undersized due to over-grinding are identified, and the characteristic parameters of the original problem area are obtained. Combined with the machining speed, an optimized grinding adjustment length is calculated. Based on this, the grinding equipment is controlled to perform reciprocating motion of the corresponding length. This operation can compensate for or finish potentially over-grinded areas, effectively eliminating the hidden dangers of localized stress concentration or dimensional inconsistencies, ensuring the dimensional uniformity and geometric integrity of the entire single-shaft, and further improving the reliability and safety of the final product.

[0119] This application discloses a method for correcting an initially quenched single rod. (Refer to...) Figure 8 The method includes: Step S801: Obtain the machining image of the corrected quenched single rod.

[0120] The processing image is an image of the surface of a quenched single rod.

[0121] Step S802: Obtain the correction status of the corrected quenched single rod through the processing image.

[0122] The correction details are used to indicate the dimensions of the corrected quenched bar surface. These correction details include at least one of the following: the corrected outer diameter, length, and surface roughness of the corrected quenched bar.

[0123] Step S803: If the correction does not conform to the preset standard size, then determine the correction area on the correction quenching rod according to the correction situation.

[0124] The correction area refers to the area where the correction does not meet the correction standard.

[0125] Optionally, when the correction involves both the actual outer diameter and the actual length, the preset standard dimensions include both the standard outer diameter and the standard length. The difference between the actual outer diameter and the standard outer diameter is calculated to obtain the outer diameter difference. The difference between the actual length and the standard length is calculated to obtain the length difference. The outer diameter difference and the length difference are used as the dimensional difference values. Problematic dimensional differences exceeding a preset dimensional difference threshold are identified from these dimensional differences, and the corresponding regions are determined to obtain the correction regions.

[0126] Optionally, when the correction includes surface roughness, the preset standard size includes the standard roughness. The difference between the surface roughness and the standard roughness is calculated to obtain the roughness difference. This roughness difference is used as the size difference. Problem size differences exceeding a preset size difference threshold are identified from the size differences, and the regions corresponding to these problem size differences are determined to obtain the correction region.

[0127] Step S804: Adjust the correction process for the initial quenched single rod according to the correction area.

[0128] For example, after determining the correction area, the correction process for the initial quenched bar is adjusted according to the location of the correction area so that the correction process can be performed on the correction area.

[0129] By adopting the above technical solution, and by acquiring and analyzing the machining images of the corrected quenched single rod, the effectiveness of previous correction processes can be inspected and evaluated in real time. If the correction results are found to be below the preset standard, the correction area requiring further processing can be accurately located based on the image analysis results, and subsequent correction processing parameters or strategies can be adjusted accordingly. This closed-loop quality control method based on vision inspection can promptly detect and correct deviations, achieving self-optimization and adjustment of the manufacturing process, significantly reducing the scrap rate, and ensuring the consistency and high quality of single rod bearing manufacturing.

[0130] Based on the same inventive concept, embodiments of this application provide a manufacturing system for a single-bar bearing, comprising: Module 901 is used to acquire dimension information; Memory 902 is used to store the program for the manufacturing method of the single rod bearing; The processor 903 can load and execute the program in the memory to implement the manufacturing method of the single rod bearing.

[0131] By employing the above technical solution, two sequential turning operations can precisely and efficiently remove excess material from the single rod, laying a solid foundation for subsequent processing. The turned single rod is then quenched, a step that significantly improves the surface hardness and wear resistance, thereby greatly enhancing the overall mechanical strength and load-bearing capacity of the final single-rod bearing and extending its service life. After quenching, by obtaining the initial dimensional information of the quenched single rod and performing targeted corrections, deformation and dimensional deviations that may occur during the quenching process can be effectively compensated and corrected, ensuring the dimensional accuracy of the single rod. Finally, the corrected and quenched single rod, meeting the required accuracy, is assembled with the rolling elements and the housing, ensuring the bearing's assembly accuracy and stable operation. This method has a clear process, balancing strength improvement and precision control, effectively improving the product quality and performance consistency of single-rod bearings.
