Description

Technical Field

[0001] This invention relates to the field of bearing testing technology, and in particular to a multifunctional testing method and equipment for tapered bearings. Background Technology

[0002] Bearing inspection is a process of comprehensively evaluating and verifying the dimensional accuracy, rotational accuracy, material properties, surface quality, internal structure, and operating characteristics of a bearing, thereby ensuring that the bearing meets quality standards, identifying potential defects, assessing remaining life, and guiding maintenance decisions.

[0003] Currently, when inspecting tapered roller bearings, the operator typically fixes the bearing on a testing platform and measures the bearing assembly height and the height difference between the inner and outer rings at multiple points on the circumference. After multiple remeasurements, the average value is taken to verify the dimensional tolerance. Next, keeping the outer ring stationary, the dial indicator probe is placed vertically against the end face of the inner ring. The inner ring is pushed to the axial limit positions on both sides, and the difference between the two readings is taken to obtain the axial movement. This measurement is repeated several times, and the average value is used for judgment. Then, the bearing is clamped onto a torque testing device and pre-run at low speed. The starting torque and steady-state torque are measured sequentially, and the torque fluctuation is observed. All items are tested and the results are judged in accordance with the corresponding standards.

[0004] Currently, the assembly height, axial movement, and torque of tapered roller bearings need to be checked sequentially by the operator, which involves a lot of manual intervention. This makes it inconvenient to collect the assembly height, axial movement, and torque data simultaneously, resulting in low testing efficiency. Summary of the Invention

[0005] To facilitate the simultaneous acquisition of assembly height, axial movement, and torque, and improve testing efficiency, this invention provides a multifunctional testing method and equipment for tapered bearings.

[0006] In a first aspect, the present invention provides a multifunctional testing method for tapered bearings, employing the following technical solution: A multifunctional testing method for tapered bearings, comprising: The preset clamping and moving device is controlled to clamp tapered bearings from different processes simultaneously and move them to the positions corresponding to the preset axial movement detection device, the preset height detection device, and the preset torque detection device, respectively, and to collect clamping detection parameters and historical detection values. The bearing specifications of the tapered bearing are determined based on the clamping and testing parameters. Retrieve the specification reference range based on bearing specifications; The test results for a single workstation are determined based on the historical test values ​​and their alignment with the specification reference range. Based on the test results of a single workstation, determine the synchronous operation scheme of the axial movement detection device, the height detection device, and the torque detection device; The synchronous operation scheme controls the movement detection device, height detection device, and torque detection device to operate, and collects the movement detection value, height detection value, and torque detection value in real time. Based on whether the movement detection value, height detection value, and torque detection value fall within the specified reference range, the detection result of the current workstation is determined; The material unloading and movement scheme is determined by combining the inspection results of a single workstation with the inspection results of the current workstation, and the tapered bearing is unloaded based on the material unloading and movement scheme.

[0007] By adopting the above technical solution, the clamping and moving device is controlled to transfer tapered bearings from different processes to each inspection station, and the clamping and inspection parameters and historical inspection values ​​are collected simultaneously. The bearing specifications are determined based on the clamping and inspection parameters and the corresponding specification reference range is retrieved. Then, the inspection results of a single station are determined to formulate and execute a synchronous operation plan for multiple devices. At the same time, multiple items are detected in real time to determine the inspection results of the current station. Then, the unloading and moving plan is determined and the clamping and moving device is controlled to unload the tapered bearings. This realizes the integrated detection of tapered bearing movement, height, and torque throughout the entire process, which facilitates the synchronous collection of assembly height, axial movement, and torque.

[0008] Optionally, methods for acquiring clamping detection parameters include: The preset clamping and moving device is controlled to clamp tapered bearings of different processes simultaneously, and the clamping distance value of the clamping jaws in the clamping and moving device is collected in real time. Calculate the spacing change value based on the clamping spacing value; When the spacing change value is 0, the spacing holding time value is collected based on the spacing change value; When the spacing holding time value is greater than the preset holding reference time value, the clamping spacing value of the clamping claw in the clamping moving device is collected and used as the clamping detection parameter.

[0009] By adopting the above technical solution, the clamping distance value is collected and the distance change value is calculated. When the distance change value is 0, the distance holding time value is collected. When the distance holding time value is greater than the preset holding reference time value, the clamping distance value is collected and used as the clamping detection parameter, thereby improving the collection accuracy of the clamping detection parameter.

[0010] Optionally, after collecting the clamping distance value of the clamping jaws in the clamping moving device and using it as a clamping detection parameter, the following steps are also included: Determine whether the clamping spacing values ​​are consistent; If yes, the data collection is complete; If not, then the inconsistent clamping distance value is selected as the distinguishing distance value; Retrieve different workstations based on the difference in spacing values; The clamping jaws in the clamping moving device corresponding to the different workstation are re-clamped to re-acquire the clamping distance value.

[0011] By adopting the above technical solution, the consistency of each clamping distance value is judged. When they are consistent, the data acquisition is completed. When they are inconsistent, the difference distance value is selected and the difference station is called to control the corresponding clamping jaw to re-clamp. At the same time, the clamping distance value is re-acquired, thereby improving the accuracy of the collected clamping detection parameters.

[0012] Optionally, after retrieving the different workstations based on the difference spacing value, the following may also be included: Select a consistent clamping distance value as the consistent distance value; Calculate the difference between the consistent spacing value and the differentiating spacing value and use it as the spacing deviation value; Determine the deviation reference range based on the consistent spacing value; Determine whether the spacing deviation value falls within the deviation reference range; If yes, the data collection is complete; If not, then determine the data acquisition plan by combining the differences in workstations and spacing deviation values, and execute the data acquisition plan.

[0013] By adopting the above technical solution, a consistent spacing value is selected and the spacing deviation value is calculated. The deviation reference range is determined by the consistent spacing value. Then, it is judged whether the spacing deviation value falls within the deviation reference range. When it falls within the range, the data acquisition is completed. When it does not fall within the range, the difference station and the spacing deviation value are combined to determine the data acquisition scheme and execute it, thereby reducing unnecessary repeated data acquisition operations and optimizing the data acquisition process of clamping detection parameters.

[0014] Optionally, the methods for determining the data collection scheme include: Determine whether the different workstation is consistent with the preset first inspection workstation; If so, then determine the spacing adjustment movement information based on the spacing deviation value; The clamping claws in the clamping moving device corresponding to the control station are de-clamped, and the position of the moving clamping claws is adjusted based on the spacing adjustment moving information to re-collect the clamping spacing value as the collection scheme. If not, the clamping jaws in the clamping moving device corresponding to the control station will be re-clamped to re-acquire the clamping distance value as the acquisition scheme.

[0015] By adopting the above technical solution, different acquisition schemes are formulated based on whether the different workstations are consistent with the first detection workstation. Two modes are adopted for different workstation scenarios: adjusting the position of the clamping claw for re-acquisition and directly re-clamping for acquisition. This can adapt to the operation characteristics of different workstations, specifically solve the problem of abnormal clamping distance in various workstations, and improve the efficiency and success rate of parameter re-acquisition.

[0016] Optionally, methods for determining the synchronous operation scheme include: Retrieve workstation type and single detection anomaly value based on single workstation detection results; Determine the adjacent type of the next adjacent workstation based on the workstation type; Determine the baseline value of the type influence between different types based on the workstation type and adjacent types; Determine whether all individual outliers detected are less than the type-affected baseline value; If so, the preset three-station operation scheme will be output as the synchronous operation scheme; If not, then select the adjacent type corresponding to a single detected outlier that is not less than the type influence benchmark value as the adjacent outlier type; Select the remaining workstation types based on adjacent anomaly types and use them as the remaining types; The remaining operation plan is determined based on the remaining type, and the abnormal stop plan is determined based on the adjacent abnormal types; The remaining operation plan and the abnormal stop plan are combined and used as a synchronous operation plan.

[0017] By adopting the above technical solution, the station type and single detection anomaly value are retrieved and adjacent types are determined. Then, the type influence benchmark value is determined. By judging whether the single detection anomaly value is less than the type influence benchmark value, if they are all less than the benchmark value, a preset three-station operation plan is output as a synchronous operation plan. If they are not all less than the benchmark value, adjacent anomaly types and remaining types are selected and the remaining operation plan and anomaly stop plan are determined respectively. These are then combined as a synchronous operation plan, thereby dynamically adjusting the collaborative working mode of the three detection devices and reducing the interference effect of a serious anomaly at one station on the detection accuracy of adjacent stations.

[0018] Optional methods for determining the material handling and movement scheme include: Based on the current workstation's inspection results, retrieve the preset final inspection anomaly value and final inspection time point corresponding to the final type. The preceding detection time point is determined based on the last detection time point; Based on the previous inspection time point, retrieve the abnormal values ​​of the previous inspection from the inspection results of a single workstation; The reference value for a single workpiece result is determined by combining the last detected anomaly value with the previous detected anomaly values. The single workpiece movement scheme is determined based on the reference value of the single workpiece result, and the single workpiece movement scheme is used as the material unloading movement scheme.

[0019] By adopting the above technical solution, the final detection anomaly value and the final detection time point are retrieved, the previous detection time point is determined, and the previous detection anomaly value is retrieved. The final detection anomaly value and the previous detection anomaly value are combined and analyzed to determine the reference value of the result for a single workpiece. Then, the single workpiece movement plan is determined based on the single workpiece result reference value and used as the unloading movement plan. In this way, the historical data and current data of the same workpiece at different detection stations are used to achieve a comprehensive evaluation of the overall quality status of the workpiece. This allows the unloading movement plan to be differentiated according to the overall qualification level of the workpiece, improving the accuracy and flexibility of unloading and sorting.

[0020] Optional methods for determining reference values ​​for individual workpiece results include: Collect the first and second adjacent influence coefficients between adjacent workstations; Retrieve the first and second abnormal values ​​based on the previous abnormal values; The second detected outlier is adjusted based on the first adjacent influence coefficient to form the second adjusted outlier; The final detected outliers are adjusted based on the second adjacent influence coefficient to form the final adjusted outliers; The first proportional value, the second proportional value, and the third proportional value are calculated and determined based on the first abnormal value, the second abnormal value, the last abnormal value, and the specification benchmark range. Calculate the average value among the first, second, and third proportional values ​​and use it as a reference value for the result of a single workpiece.

[0021] By adopting the above technical solution, the first adjacent influence coefficient and the second adjacent influence coefficient are determined, and the first detection anomaly value and the second detection anomaly value are retrieved. Then, the second adjustment anomaly value and the final adjustment anomaly value are obtained. The first proportion value, the second proportion value and the third proportion value are calculated and determined. Then, the average value is calculated as the reference value of the result of a single workpiece. This makes the reference value of the result of a single workpiece more realistically reflect the comprehensive deviation of the tapered bearing in terms of movement, height and torque, and provides a more scientific quantitative basis for the material cutting and moving scheme.

[0022] Secondly, the present invention provides a multifunctional testing device for tapered bearings, which adopts the following technical solution: A multifunctional testing device for tapered bearings, employing a multifunctional testing method for tapered bearings as described in any one of the first aspects, comprising: A placement platform for placing tapered bearings; A movement detection device is installed on the placement platform and is used to detect movement of tapered bearings; A height detection device is installed on the placement platform for detecting the assembly height of the tapered bearing; A torque detection device is installed on the placement platform for detecting the torque of the tapered bearing; A clamping and moving device is provided on the placement platform for synchronously clamping and moving several tapered bearings; The axial movement detection device, the height detection device, and the torque detection device are sequentially distributed on the placement platform. The clamping and moving device moves several tapered bearings sequentially to the axial movement detection device, the height detection device, and the torque detection device for synchronous detection.

[0023] By adopting the above technical solution, the axial movement detection device, the height detection device, and the torque detection device are sequentially distributed on the placement platform, and a clamping and moving device is configured to clamp and move several tapered bearings synchronously. This achieves a parallel operation mode in which multiple bearings are simultaneously tested for different parameters at different workstations, facilitating the synchronous acquisition of assembly height, axial movement, and torque.

[0024] Optionally, the clamping and moving device includes a clamping jaw for clamping the tapered bearing, a clamping drive for driving the clamping jaw to open or close, and a moving assembly. The clamping jaw is disposed on the clamping drive, the moving assembly is disposed on the placement platform, and a plurality of clamping drives are disposed on the moving assembly. The moving assembly is used to drive the clamping drives to move.

[0025] By adopting the above technical solution, the moving component drives the clamping drive to move, thereby causing the clamping drive to move the clamping jaws. The clamping drive controls the opening or closing of the clamping jaws, thus enabling the simultaneous synchronous movement of several clamping jaws and the individual clamping control of several clamping jaws, which facilitates the inspection of tapered bearings at different workstations.

[0026] In summary, the present invention has at least one of the following beneficial technical effects: 1. The control clamping and moving device moves tapered bearings from different processes to each inspection station, simultaneously collecting clamping and inspection parameters and historical inspection values. Based on the clamping and inspection parameters, the bearing specifications are determined and the corresponding specification reference range is retrieved. The inspection results of a single station are then confirmed to formulate and execute a synchronous operation plan for multiple devices. At the same time, multiple items are inspected in real time to determine the inspection results of the current station. Then, the unloading and moving plan is determined and the clamping and moving device is controlled to unload the tapered bearings. This achieves integrated inspection of tapered bearing movement, height, and torque throughout the entire process, facilitating the synchronous collection of assembly height, axial movement, and torque. 2. Collect the clamping spacing value and calculate the spacing change value. When the spacing change value is 0, collect the spacing holding time value. When the spacing holding time value is greater than the preset holding reference time value, collect the clamping spacing value and use it as the clamping detection parameter to improve the collection accuracy of the clamping detection parameter. 3. The final inspection anomaly value and the final inspection time point are retrieved to determine the previous inspection time point and retrieve the previous inspection anomaly value. The final inspection anomaly value and the previous inspection anomaly value are combined and analyzed to determine the reference value of the result for a single workpiece. Then, the single workpiece movement plan is determined based on the single workpiece result reference value and used as the unloading movement plan. In this way, the historical data and current data of the same workpiece at different inspection stations are used to achieve a comprehensive evaluation of the overall quality status of the workpiece. This allows the unloading movement plan to be differentiated according to the overall qualification level of the workpiece, improving the accuracy and flexibility of unloading and sorting.

The movement detection device 2, height detection device 3, and torque detection device 4 are sequentially arranged on the same side along the length of the placement platform 1 to facilitate simultaneous testing of the tapered roller bearings on the placement platform 1. In this embodiment, the tapered roller bearings first pass through the workstation corresponding to the movement detection device 2, then through the workstation corresponding to the height detection device 3, and finally through the workstation corresponding to the torque detection device 4.

[0031] Reference Figure 1 The clamping and moving device 5 is used to synchronously clamp and move several tapered bearings. The clamping and moving device 5 includes clamping claws 6, clamping drive members 7 for opening or closing the clamping claws 6, and a moving assembly 8. The moving assembly 8 is installed on the side of the placement platform 1 away from the movement detection device 2, height detection device 3, or torque detection device 4. The moving assembly 8 includes a first moving member for driving the clamping drive member 7 to move along the length of the placement platform 1 and a second moving member for driving the clamping drive member 7 to move closer to the movement detection device 2, height detection device 3, or torque detection device 4. Several clamping drive members 7 are provided and installed on the moving assembly 8. The clamping claws 6 are installed on the side of the clamping drive member 7 closer to the movement detection device 2, height detection device 3, or torque detection device 4, and are used to clamp the tapered bearings. Both the first and second moving members can be hydraulic cylinders, pneumatic cylinders, or stepper motors.

[0032] Reference Figure 1 The clamping and moving device 5 synchronously clamps and moves several tapered bearings, thereby moving the several tapered bearings to the workstations corresponding to the axial movement detection device 2, height detection device 3, and torque detection device 4 for synchronous detection, which facilitates the synchronous acquisition of assembly height, axial movement, and torque.

[0033] Reference Figure 2 Based on the same inventive concept, embodiments of the present invention provide a multifunctional testing method for tapered bearings, including: S100: Control the preset clamping and moving device 5 to clamp the tapered bearings of different processes at the same time and move them to the positions corresponding to the preset axial movement detection device 2, the preset height detection device 3, and the preset torque detection device 4, and collect clamping detection parameters and historical detection values.

[0034] Among them, the clamping detection parameters refer to the characteristic data reflecting the clamping state collected in real time during the clamping process. The clamping detection parameters include the clamping distance of the clamping jaws 6 (the opening distance between the two jaws) and the clamping force (the clamping force applied by the jaws to the bearing), etc. The clamping detection parameters are obtained by displacement sensors and pressure sensors preset on the clamping moving device 5.

[0035] Historical test values ​​refer to the movement, assembly height, or torque values ​​of the same tapered bearing that have been measured and recorded in a previous process or several previous operations.

[0036] For example, the historical detection value for the tapered bearing at the station corresponding to the movement detection device 2 is empty. The historical detection value for the tapered bearing at the station corresponding to the height detection device 3 is the movement amount detected by the movement detection device 2. The historical detection value for the tapered bearing at the station corresponding to the torque detection device 4 is the movement amount detected by the movement detection device 2 and the assembly height detected by the height detection device 3.

[0037] S101: Determine the bearing specifications of the tapered bearing based on the clamping and detection parameters.

[0038] Among them, bearing specifications refer to a set of technical parameters used to characterize the model, size series and structural features of tapered bearings.

[0039] By retrieving the clamping distance from the clamping detection parameters and using it as the outer diameter of the tapered bearing, and then querying and matching the model database based on the outer diameter of the tapered bearing to obtain the bearing specification, it is convenient for subsequent use.

[0040] The model database pre-stores different tapered bearing models, dimensions, and corresponding ranges of runout, assembly height, and friction torque. The model database is retrieved after the operator pre-inputs the data.

[0041] S102: Retrieve the specification reference range based on bearing specifications.

[0042] Among them, the specification reference range refers to the range of allowable values ​​that are pre-set for a specific bearing specification to determine whether its movement, assembly height and friction torque are qualified.

[0043] The bearing specifications are retrieved from the model database to obtain the corresponding specification reference range, which facilitates subsequent use.

[0044] S103: Determine the test result for a single workstation based on the historical test values ​​and the range of specification benchmarks.

[0045] Among them, the single-station test result refers to the test result of the tapered bearing at a specific station in one of the two independent stations of historical movement test or height test.

[0046] The corresponding specification reference range is selected by the parameter type of the historical detection value, and the fall-in case is judged. When the historical detection value falls within the corresponding specification reference range, 0 is output as a single detection anomaly value. When the historical detection value does not fall within the corresponding specification reference range, the difference between the historical detection value and the nearest value of the corresponding specification reference range is calculated as a single detection anomaly value. Then, the single detection anomaly value is combined with the type corresponding to the workstation to obtain the single workstation detection result, which is convenient for subsequent use.

[0047] S104: Determine the synchronous operation scheme of the axial movement detection device 2, height detection device 3 and torque detection device 4 based on the detection results of a single workstation.

[0048] Among them, the synchronous operation scheme refers to the execution strategy of synchronizing the operation of the lateral movement detection device 2, the height detection device 3, and the torque detection device 4, or suspending the operation of one of the devices.

[0049] By analyzing the detection results of a single workstation, a synchronous operation plan can be determined to facilitate subsequent use.

[0050] S105: Based on the synchronous operation scheme, control the movement detection device 2, height detection device 3 and torque detection device 4 to operate, and collect movement detection values, height detection values ​​and torque detection values ​​in real time.

[0051] Among them, the axial movement detection value refers to the specific value of the axial movement of the tapered bearing directly measured by the axial movement detection device 2 during actual operation. The height detection value refers to the specific value of the bearing assembly height measured in real time by the height detection device 3. The torque detection value refers to the specific value of the frictional torque measured in real time by the torque detection device 4 during the bearing rotation process.

[0052] The lateral movement detection device 2, height detection device 3, and torque detection device 4 are controlled to operate in a synchronous mode. The lateral movement detection device 2 detects the lateral movement value, the height detection device 3 detects the height value, and the torque detection device 4 detects the torque value, which facilitates subsequent use.

[0053] S106: Determine the current station's detection result based on whether the movement detection value, height detection value, and torque detection value fall within the specified reference range.

[0054] The current station test result refers to the test result of the tapered bearing at one of the three independent stations: current movement test, height test, or torque test.

[0055] By matching the axial movement detection values, height detection values, and torque detection values ​​one by one with the corresponding specification reference ranges, the detection results of the current workstation are determined for subsequent use. The specific method for determining the detection results of the current workstation is described in S103.

[0056] S107: Determine the material unloading movement plan by combining the detection results of a single workstation with the detection results of the current workstation, and unload the tapered bearing based on the material unloading movement plan.

[0057] The material handling and moving scheme refers to the specific execution strategy used to move qualified tapered bearings to the next inspection station or to discard abnormal tapered bearings.

[0058] By combining and analyzing the test results of a single workstation with the test results of the current workstation, it is determined whether the tapered bearing is qualified. Based on the qualified result, the corresponding material unloading and movement plan is determined, and the tapered bearing is unloaded according to the material unloading and movement plan. This realizes the integrated detection of tapered bearing movement, height, and torque throughout the entire process, and facilitates the synchronous acquisition of assembly height, axial movement, and torque.

[0059] To further ensure the rationality of the clamping detection parameters, it is necessary to perform further separate analysis and calculation on the clamping detection parameters, which will be explained in detail through the steps shown below.

[0060] Reference Figure 3 The method for acquiring clamping detection parameters includes the following steps: S200: Control the preset clamping and moving device 5 to clamp tapered bearings of different processes simultaneously, and collect the clamping distance value of the clamping claws 6 in the clamping and moving device 5 in real time.

[0061] The clamping distance value refers to the opening distance between the two jaws of the clamping jaw 6.

[0062] The control clamping and moving device 5 simultaneously clamps tapered bearings from different processes and collects the clamping distance values ​​for subsequent use.

[0063] S201: Calculate the spacing change value based on the clamping spacing value.

[0064] The pitch change value refers to the difference in the amplitude of the fluctuation of the clamping pitch over time during the clamping of the tapered bearing.

[0065] The clamping distance between two adjacent sampling times is calculated, and the calculation result is used as the distance change value for convenient subsequent use.

[0066] S202: When the spacing change value is 0, collect the spacing holding time value based on the spacing change value.

[0067] Among them, the spacing holding time value refers to the duration after the clamping spacing value of the clamping jaw 6 reaches stability for the first time after clamping the tapered bearing.

[0068] When the spacing change value is 0, the time point corresponding to the spacing change value remaining at 0 is timed, and the timing result is used as the spacing holding time value for convenient subsequent use.

[0069] S203: When the spacing holding time value is greater than the preset holding reference time value, the clamping spacing value of the clamping claw 6 in the clamping moving device 5 is collected and used as the clamping detection parameter.

[0070] The hold reference time value refers to the minimum duration preset to determine when the clamping has reached true stability. The hold reference time value is preset by the operator according to requirements.

[0071] When the spacing holding time is greater than the preset holding reference time, it indicates that the clamping is stable. Therefore, the clamping spacing value is collected and used as a clamping detection parameter for convenient subsequent use.

[0072] To further ensure the rationality of the clamping detection parameters, it is necessary to perform further separate analysis and calculation on the clamping detection parameters, which will be explained in detail through the steps shown below.

[0073] After collecting the clamping distance value of the clamping jaws 6 in the clamping moving device 5 and using it as a clamping detection parameter, the following steps are also included: S300: Determine whether the clamping distance values ​​are consistent. If yes, proceed to S301; if no, proceed to S302.

[0074] In this process, the consistency of each clamping spacing value is checked to determine whether there is any abnormality in the clamped tapered bearing.

[0075] S301: Data collection complete.

[0076] When all clamping distance values ​​are consistent, it indicates that the clamped tapered bearing is not abnormal, and the data collection is completed.

[0077] S302: Select inconsistent clamping distance values ​​as the distinguishing distance values.

[0078] Among them, the difference in spacing value refers to inconsistent clamping spacing values.

[0079] When the clamping spacing values ​​are inconsistent, it indicates that there is an abnormality in the clamped tapered bearing. Therefore, the inconsistent clamping spacing values ​​are selected as the distinguishing spacing values ​​for convenient subsequent use.

[0080] S303: Retrieve different workstations based on the difference spacing value.

[0081] Among them, the differentiated workstation refers to the workstation corresponding to the differentiated spacing value.

[0082] By retrieving the workstations of the axial movement detection device 2, height detection device 3, or torque detection device 4 corresponding to the differentiating spacing values ​​and using them as differentiating workstations, it is convenient for subsequent use.

[0083] S304: Control the clamping claws 6 in the clamping moving device 5 corresponding to the different workstation to re-clamp and re-acquire the clamping distance value.

[0084] Specifically, the clamping claw 6 in the clamping and moving device 5 corresponding to the control station lowers the tapered bearing, then controls the re-clamping of the tapered bearing, and collects the clamping distance value during the clamping process to improve the accuracy of the obtained clamping distance value.

[0085] To further ensure the rationality of retrieving the different workstations based on the difference spacing value, it is necessary to perform further separate analysis and calculation on the workstations retrieved based on the difference spacing value. The specific steps are explained in detail below.

[0086] After retrieving the distinct workstations based on the distinct spacing values, the following steps are also included: S400: Select a consistent clamping distance value as the consistent distance value.

[0087] Among them, consistent spacing value refers to consistent clamping spacing value.

[0088] Selecting a consistent spacing value facilitates subsequent use.

[0089] S401: Calculate the difference between the consistent spacing value and the differentiating spacing value and use it as the spacing deviation value.

[0090] The spacing deviation value refers to the difference between the consistent spacing value and the distinguishing spacing value.

[0091] Calculating the spacing deviation value facilitates subsequent use.

[0092] S402: Determine the deviation reference range based on the consistent spacing value.

[0093] The deviation reference range refers to the maximum acceptable range for determining the difference interval value.

[0094] The deviation reference interval is formed by calculating the product between the consistent spacing value and the preset deviation tolerance coefficient, and using the positive and negative values ​​corresponding to the calculation results as the endpoints of the deviation reference interval, which is convenient for subsequent use.

[0095] The deviation tolerance factor is a proportional coefficient that allows for deviations. The deviation tolerance factor is set in advance by the operator according to actual needs.

[0096] S403: Determine whether the spacing deviation value falls within the deviation reference range. If yes, proceed to S404; if no, proceed to S405.

[0097] Specifically, by judging whether the spacing deviation value falls within the deviation reference range, it is determined whether the difference spacing value meets the tolerance condition.

[0098] S404: Data collection complete.

[0099] When the spacing deviation value falls within the deviation reference range, it indicates that the difference spacing value meets the tolerance condition, and the data collection is completed.

[0100] S405: Determine the data acquisition plan by combining the differences between workstations and the spacing deviation value, and execute the data acquisition plan.

[0101] The acquisition scheme refers to the scheme for acquiring clamping and detection parameters.

[0102] When the spacing deviation value does not fall within the deviation reference range, it indicates that the difference spacing value does not meet the tolerance condition. Therefore, the difference station and the spacing deviation value are analyzed together to determine the acquisition scheme and execute the acquisition scheme to improve the accuracy of the acquired clamping detection parameters.

[0103] To further ensure the rationality of the data acquisition plan, it is necessary to conduct further separate analysis and calculations on the plan, which will be explained in detail through the steps shown below.

[0104] The method for determining the data collection plan includes the following steps: S500: Determine whether the differentiation station is consistent with the preset first detection station. If yes, execute S501; if no, execute S503.

[0105] In this context, the first inspection station refers to the station that performs the inspection first in the process flow among the three stations arranged sequentially: movement detection, height detection, and torque detection. The first inspection station is preset by the operator based on actual needs. In this embodiment, the first inspection station is the station corresponding to movement detection.

[0106] By determining whether the different workstation matches the preset first detection workstation, it can be determined whether the clamping position needs to be adjusted.

[0107] S501: Determine the spacing adjustment movement information based on the spacing deviation value.

[0108] Among them, the spacing adjustment movement information refers to the direction and displacement data of the gripper 6 that needs to move.

[0109] When the differentiating station matches the preset first detection station, it indicates that the clamping position needs to be adjusted. Therefore, the direction of movement is determined based on the sign of the spacing deviation value, and the value corresponding to the spacing deviation value is used as the displacement amount, thereby obtaining the spacing adjustment movement information.

[0110] S502: Control the clamping claw 6 in the clamping moving device 5 corresponding to the different workstation to cancel clamping, and adjust the position of the moving clamping claw 6 based on the spacing adjustment moving information to re-collect the clamping spacing value as the collection scheme.

[0111] Specifically, by controlling the clamping claw 6 in the clamping moving device 5 corresponding to the different workstation to unclamp the tapered bearing, and then adjusting the position of the moving clamping claw 6 according to the spacing adjustment moving information, the clamping claw 6 is controlled to grip the tapered bearing, thereby collecting the clamping spacing value, and the above control scheme is used as the collection scheme to improve the accuracy of the acquired collection scheme.

[0112] S503: Re-clamp the clamping claw 6 in the clamping moving device 5 corresponding to the control differentiation station to re-collect the clamping distance value as the acquisition scheme.

[0113] When the differentiating station is inconsistent with the preset first detection station, it means that there is no need to adjust the clamping position. Therefore, the clamping claw 6 in the clamping moving device 5 corresponding to the differentiating station is directly re-clamped to re-collect the clamping distance value as the acquisition scheme, thereby improving the accuracy of the acquired acquisition scheme.

[0114] To further ensure the rationality of the synchronous operation scheme, it is necessary to conduct a more detailed separate analysis and calculation of the synchronous operation scheme, which will be explained in detail through the steps shown below.

[0115] The method for determining a synchronous operation scheme includes the following steps: S600: Retrieves station type and single detection anomaly value based on single station detection results.

[0116] The "station type" refers to the category to which each of the three inspection stations belongs. Station types include movement detection station, height detection station, and torque detection station. A single outlier refers to the quantified data showing the degree to which the actual measured value at a specific station deviates from the boundary of the station's specification reference range in historical inspections.

[0117] The station type and single detection anomaly value can be retrieved by using the detection results of a single station, which is convenient for subsequent use.

[0118] S601: Determine the adjacent type corresponding to the next adjacent workstation based on the workstation type.

[0119] The adjacent type refers to the station type corresponding to the first adjacent inspection station encountered when moving from the current station to the next process along the sequence of the tapered bearing inspection process.

[0120] By matching the workstation type with the preset inspection process steps, adjacent types are obtained for convenient subsequent use. The inspection process steps are pre-stored with the sequential steps used in the tapered bearing inspection process.

[0121] S602: Determine the type influence baseline value corresponding to the mutual influence between different types based on the workstation type and adjacent types.

[0122] Among them, the type impact benchmark value refers to the maximum abnormal value that is used to measure the abnormal quantity corresponding to a certain workstation type when it does not interfere with the detection of adjacent workstation types.

[0123] By inputting the workstation type and adjacent types into a preset type database, a type influence benchmark value is obtained for easy subsequent use.

[0124] The type database pre-stores a table of different workstation types, adjacent types, and their corresponding type influence benchmark values. The type database is obtained by the operator after detecting the workstations corresponding to adjacent types with different anomaly detection quantities corresponding to the initial workstation type.

[0125] S603: Determine whether all individual outlier detection values ​​are less than the type-affected baseline value. If yes, proceed to S604; if no, proceed to S605.

[0126] Among them, the ability to operate all three workstations simultaneously is determined by judging whether all single outlier values ​​are less than the type-affected baseline value.

[0127] S604: Outputs a preset three-station operation scheme and uses it as a synchronous operation scheme.

[0128] The three-station operation plan refers to the scheme used to control the synchronous operation of the axial movement detection device 2, the height detection device 3, and the torque detection device 4. The three-station operation plan is obtained after being pre-input by the operator.

[0129] When all single-detection anomaly values ​​are less than the type-affected baseline value, it indicates that all three workstations can operate simultaneously. Therefore, the preset three-workstation operation plan is output as the synchronous operation plan.

[0130] S605: Select the adjacent types corresponding to a single detected outlier that is not less than the type influence benchmark value as the adjacent outlier types.

[0131] Among them, adjacent anomaly type refers to the adjacent type corresponding to a single detected anomaly value that is not less than the type influence benchmark value.

[0132] When the single detection anomaly value is not less than the type influence benchmark value, it means that the three workstations cannot run together at this time. Therefore, adjacent anomaly types are selected for convenient subsequent use.

[0133] S606: Select the remaining workstation type based on the adjacent abnormality type and use it as the remaining type.

[0134] Among them, the remaining type refers to the workstation type other than the adjacent abnormal type.

[0135] By removing adjacent exception types from all workstation types, the remaining types are obtained, making them easier to use later.

[0136] S607: Determine the remaining operation plan based on the remaining type, and determine the abnormal stop plan based on the adjacent abnormal type.

[0137] The remaining operation plan refers to the operation strategy formulated only for the detection devices corresponding to the remaining types. The abnormal stop plan refers to the stop strategy formulated for the detection devices corresponding to adjacent abnormal types.

[0138] The remaining types are input into a preset type operation database to obtain the remaining operation schemes. Then, the adjacent abnormal types are combined with the preset stop operation signals to form an abnormal stop scheme, which is convenient for subsequent use.

[0139] The type operation database pre-stores a table of different workstation types and their corresponding operation plans, which is retrieved after the operator pre-inputs the information.

[0140] S608: Combine the remaining operation plan with the abnormal stop plan and use it as a synchronous operation plan.

[0141] In this way, by combining the remaining operation schemes with the abnormal stop schemes, a scheme set is formed and used as a synchronous operation scheme, thereby improving the accuracy of the obtained synchronous operation scheme.

[0142] To further ensure the rationality of the material feeding and moving scheme, it is necessary to conduct a more detailed separate analysis and calculation of the material feeding and moving scheme, which will be explained in detail through the steps shown below.

[0143] The method for determining the material handling and movement scheme includes the following steps: S700: Based on the current workstation's detection results, retrieve the preset last detection anomaly value and last detection time point corresponding to the last type.

[0144] Here, "last type" refers to the type of the last workstation to be inspected. The last type is obtained through pre-input by the operator. In this embodiment, the last type is the torque detection workstation type.

[0145] The final inspection anomaly refers to the quantitative value by which the current inspection of the workstation corresponding to the final type deviates from its specification baseline range. The final inspection time point refers to the time point at which the inspection of the workstation corresponding to the final type was carried out.

[0146] The current workstation's inspection results can be used to retrieve the final inspection anomaly value and the final inspection time point corresponding to the final type, facilitating subsequent use.

[0147] S701: Determine the preceding detection time point based on the last detection time point.

[0148] Among them, the preceding inspection time point refers to the time point corresponding to the inspection performed at the workstation before the final type.

[0149] By calculating the time interval between the final inspection time and the preset process interval, the previous inspection time can be calculated backwards for convenient use later.

[0150] Process interval time refers to the reference time between different workstations when the same tapered bearing is inspected. Process interval time is obtained through pre-input by the operator.

[0151] S702: Retrieve abnormal values ​​from the previous inspection results of a single workstation based on the previous inspection time point.

[0152] Among them, the abnormal value of the preceding detection refers to the abnormal value corresponding to the detection at the workstation before the final type.

[0153] By taking the single detection anomaly value corresponding to the previous detection time point from the single workstation detection result and using it as the previous detection anomaly value, it is convenient for subsequent use.

[0154] S703: Combine the last detected abnormal value with the previous detected abnormal value to determine the reference value of the result for a single workpiece.

[0155] Among them, the single workpiece result reference value refers to the reference value used to determine whether the same workpiece is qualified.

[0156] By combining and analyzing the final abnormal values ​​with the previous abnormal values, a reference value for the result of a single workpiece can be determined, which will facilitate subsequent use.

[0157] S704: Determine the single workpiece movement scheme based on the reference value of the single workpiece result, and use the single workpiece movement scheme as the material unloading movement scheme.

[0158] Among them, the single workpiece movement scheme refers to the material cutting scheme specified based on the reference value of a single workpiece result.

[0159] By comparing the result reference value of a single workpiece with the preset result benchmark reference value, when the result reference value of a single workpiece is less than the preset result benchmark reference value, it indicates that the inspection is qualified at this time, so the preset qualified movement scheme is used as the single workpiece movement scheme. When the result reference value of a single workpiece is not less than the preset result benchmark reference value, it indicates that the inspection is unqualified at this time, so the preset abnormal discard scheme is used as the single workpiece movement scheme, and then the single workpiece movement scheme is used as the unloading movement scheme, thereby improving the accuracy of the obtained unloading movement scheme.

[0160] The result reference value refers to the reference value corresponding to meeting the acceptance requirements. The result reference value is obtained after pre-input by the operator. The acceptable movement plan is the movement plan used to control the inspection of the next process step, and the abnormal rejection plan is the movement plan used to control the rejection of unacceptable tapered bearings. Both the acceptable movement plan and the abnormal rejection plan are obtained after pre-input by the operator.

[0161] To further ensure the rationality of the reference values ​​for individual workpiece results, it is necessary to perform further separate analysis and calculation on the reference values ​​for individual workpiece results, which will be explained in detail through the steps shown below.

[0162] The method for determining the reference value of a single workpiece result includes the following steps: S800: Collect the first and second adjacent influence coefficients between adjacent workstations.

[0163] The first adjacent influence coefficient is a weighting factor used to quantify the degree of mutual interference between the two workstations, the axial movement detection device 2 and the height detection device 3. The second adjacent influence coefficient is a weighting factor used to quantify the degree of mutual interference between the two workstations, the height detection device 3 and the torque detection device 4. Both the first and second adjacent influence coefficients are decimals between 0 and 1.

[0164] The interference is measured by running the preceding station (e.g., the sway detection device 2) independently, while simultaneously using a vibration sensor and an electromagnetic probe installed at the following station (e.g., the height detection device 3). Then, the following station is run independently to measure its signal amplitude during normal detection. Dividing the interference by the normal signal amplitude of the following station yields an approximate value for the first adjacent influence coefficient. The second adjacent influence coefficient is then collected for subsequent use.

[0165] S801: Retrieve the first and second abnormal detection values ​​based on the previous abnormal detection values.

[0166] The first abnormal value refers to the abnormal value corresponding to the movement detection device 2. The second abnormal value refers to the abnormal value corresponding to the height detection device 3.

[0167] The first and second outliers are retrieved by detecting outliers in the preceding steps, which facilitates their subsequent use.

[0168] S802: Adjust the second detected outlier based on the first adjacent influence coefficient to form the second adjusted outlier.

[0169] The second adjusted outlier refers to the outlier after adjusting the second detected outlier.

[0170] The product of the first adjacent influence coefficient and the second detected outlier is calculated, and the result is used as the second adjusted outlier for convenient subsequent use.

[0171] S803: Adjust the last detected outlier based on the second adjacent influence coefficient to form the final adjusted outlier.

[0172] Among them, the last adjusted outlier refers to the outlier corresponding to the last detected outlier.

[0173] The product of the second adjacent influence coefficient and the last detected outlier is calculated, and the result is used as the final adjusted outlier for convenient subsequent use.

[0174] S804: The first proportional value, the second proportional value, and the third proportional value are calculated and determined based on the first detection anomaly value, the second adjustment anomaly value, the last adjustment anomaly value, and the specification benchmark range.

[0175] The first proportional value refers to the ratio between the first detected outlier and the specification baseline range. The second proportional value refers to the ratio between the second adjusted outlier and the specification baseline range. The third proportional value refers to the ratio between the last adjusted outlier and the specification baseline range.

[0176] The ratio between the first detected outlier and the nearest value in the corresponding specification reference range is calculated, and the result is used as the first ratio value. Then, the ratio between the second adjusted outlier and the nearest value in the corresponding specification reference range is calculated, and the result is used as the second ratio value. Finally, the ratio between the last adjusted outlier and the nearest value in the corresponding specification reference range is calculated, and the result is used as the third ratio value.

[0177] S805: Calculate the average value among the first, second, and third proportional values ​​and use it as a reference value for the result of a single workpiece.

[0178] Specifically, by calculating the average value among the first, second, and third proportional values, and using the calculation result as a reference value for a single workpiece, the accuracy of the obtained reference value for a single workpiece is improved.
