Description

Technical Field

[0001] This invention relates to the field of synchronizer slider manufacturing technology, and in particular to an automatic assembly method and apparatus for synchronizer sliders. Background Technology

[0002] The synchronizer slider is a small, axially sliding part installed in the groove of the gear hub in an automotive transmission synchronizer. At the beginning of gear shifting, the synchronizer slider pushes the synchronizer ring to contact and synchronize the speed of the gears to be engaged, preparing for a smooth shift.

[0003] Synchronizer sliders generally consist of a T-shaped slider, a spring, and steel balls. The T-shaped slider has a groove in the middle for placing the spring and steel balls. Typically, the spring is first manually inserted into the groove of the T-shaped slider, and then the steel balls are pressed into the groove of the T-shaped slider to complete the assembly of the synchronizer slider.

[0004] Because springs and steel balls are generally small in size, they are prone to slipping during manual assembly, resulting in low assembly efficiency. Summary of the Invention

[0005] To improve the assembly efficiency of synchronizer sliders, this invention provides an automatic assembly method and apparatus for synchronizer sliders.

[0006] In a first aspect, the present invention provides an automatic assembly method for a synchronizer slider, employing the following technical solution: An automatic assembly method for a synchronizer slider includes: The slider body specifications are acquired in response to the first feeding end signal of the preset first feeding device, and the spring specifications are acquired in response to the second feeding end signal of the preset second feeding device. The first clamping control information is determined by combining the specifications of the slider body and the spring, and the first clamping device is controlled to operate based on the first clamping control information to collect the first clamping detection information; The steel ball specifications are collected in response to the preset third feeding end signal of the third feeding device; The second clamping control information is determined by combining the specifications of the slider body, spring, and steel ball, and the operation of the preset second clamping device is controlled based on the second clamping control information to collect the second clamping detection information; The assembly reference parameters are determined based on the first and second clamping detection information. Assembly and testing parameters are collected based on a pre-set assembly and testing device; The material feeding control information is determined based on the assembly reference parameters and assembly inspection parameters, and the operation of the preset material feeding device is controlled based on the material feeding control information.

[0007] By adopting the above technical solution, the specifications of the slider body, spring, and steel ball are collected sequentially through the first, second, and third feeding end signals. The first and second clamping control information are generated step by step, and two-level clamping detection is completed. Then, the assembly reference parameters are determined and the unloading control information is generated in combination with the collected assembly detection parameters to control the operation of the unloading device. This realizes the full-process automation and parameterized control of the synchronizer slider assembly, improves the adaptability of different specification parts assembly, reduces the slippage of springs and steel balls during assembly, and improves the assembly efficiency of the synchronizer slider.

[0008] Optionally, the method for determining the first clamping control information includes: The groove diameter and groove depth are determined based on the slider body specifications. Retrieve spring diameter, spring length, and elastic parameters based on spring specifications; Calculate the ratio between the groove diameter and the spring diameter and use it as the diameter ratio value; Calculate the ratio between the spring length and the groove depth and use it as the length ratio value; The required clamping depth is determined by combining the diameter ratio and the length ratio. The required spring clamping force is determined by combining the elastic parameters and the required clamping depth, and the required spring clamping force and the required clamping depth are combined as the first clamping control information.

[0009] By adopting the above technical solution, the groove diameter and groove depth are retrieved through the slider body specifications, and the spring diameter, spring length, and elastic parameters are retrieved through the spring specifications. The diameter ratio and length ratio are calculated by combining multiple parameters. The required depth of the dimensional clamping is generated, and the required spring clamping force is determined. The required spring clamping force and the required dimensional clamping depth are combined to form the first clamping control information. This allows the stroke parameters and pressure parameters of the spring clamping to be accurately matched with the slider groove structure dimensions and the elastic characteristics of the spring itself, thereby improving the parameter matching accuracy of the spring and slider body pre-assembly process.

[0010] Optionally, the method for determining the second clamping control information includes: Based on the specifications of the steel balls, retrieve the diameter and mass of the steel balls; Calculate the sum of the steel ball diameter and the spring length and use it as the overall assembly length; Calculate the ratio between the groove depth and the overall assembly length and use it as the assembly ratio value; Determine the required assembly clamping depth based on the assembly ratio value; The required clamping force of the steel ball is determined by combining the steel ball mass, steel ball diameter, and groove diameter, and the required clamping force of the steel ball is combined with the required clamping depth of the assembly as the second clamping control information.

[0011] By adopting the above technical solution, based on the matching of slider and spring parameters, the diameter and mass parameters of steel ball are introduced to calculate the assembly ratio value to determine the required assembly clamping depth. The required clamping force of steel ball is determined by combining the mass, diameter and groove diameter of steel ball. The required clamping force of steel ball and the required assembly clamping depth are combined to form the second clamping control information, thereby optimizing the assembly posture and fit clearance of steel ball and improving the overall assembly matching accuracy.

[0012] Optional methods for determining the required clamping force of the steel balls include: Calculate the ratio between the diameter of the steel ball and the diameter of the groove, and use it as the interference ratio. Determine the required force for over-interference compression based on the over-interference ratio; The required force for mass adjustment is determined by combining the elastic parameters and the mass of the steel ball. Calculate the ratio between the mass adjustment demand force and the interference clamping demand force, and use it as the demand force ratio value; Determine whether the demand ratio is less than the preset demand baseline ratio. If so, the interference clamping force is taken as the steel ball clamping force. If not, then determine the proportional adjustment coefficient based on the demand force ratio; Calculate the product between the proportional adjustment coefficient and the interference clamping force and use it as the steel ball clamping force.

[0013] By adopting the above technical solution, the interference clamping force is determined by the interference ratio between the steel ball and the groove. The mass adjustment force is determined by combining the elastic parameters of the spring and the mass of the steel ball. The required force ratio is calculated, and it is then judged whether the required force ratio is less than the preset required force benchmark ratio. The steel ball clamping force is obtained adaptively according to different working conditions. Thus, the clamping force is dynamically adjusted by the interference fit state of the parts, the elastic performance of the spring, and the self-weight characteristics of the steel ball, thereby improving the assembly fit accuracy of the steel ball and the consistency of batch assembly.

[0014] Optionally, after collecting the first or second clamping detection information, the following may also be included: Determine whether the first clamping detection information is consistent with the first clamping control information, or determine whether the second clamping detection information is consistent with the second clamping control information; If all are consistent, then continue to collect the steel ball specifications or determine the assembly reference parameters; If there is a discrepancy, when the first clamping detection information and the first clamping control information are inconsistent, the first clamping deviation parameter shall be determined based on the comparison result between the first clamping detection information and the first clamping control information. The first clamping adjustment information is determined based on the first clamping deviation parameter; The first clamping adjustment information is combined with the preset reset control information and used as the first clamping reset information to execute the first clamping reset information; When the second clamping detection information is inconsistent with the second clamping control information, the second clamping deviation parameter is determined based on the comparison result between the second clamping detection information and the second clamping control information. The second clamping adjustment information is determined based on the second clamping deviation parameter; The second clamping adjustment information is combined with the preset reset control information and used as the second clamping reset information to execute the second clamping reset information.

[0015] By adopting the above technical solution, after the clamping test is completed, the clamping test information and the corresponding clamping control information are compared in real time. For working conditions with deviations, the first clamping deviation parameter and the second clamping deviation parameter are identified respectively. The corresponding clamping adjustment information is generated and combined with the reset control information to complete the mechanism reset correction. This realizes real-time self-inspection, deviation identification and dynamic correction of the two-level clamping process, timely compensation for clamping deviations in the assembly process, reducing the probability of assembly defects, improving the pass rate of each pre-assembly process, and ensuring the smooth progress of subsequent assembly processes.

[0016] Optionally, methods for determining assembly datum parameters include: The first movement deviation value, the first clamping force deviation value, and the deviation duration value are retrieved based on the first clamping deviation parameter; the second movement deviation value and the second clamping force deviation value are retrieved based on the second clamping deviation parameter. The first deviation adjustment coefficient is determined by combining the first movement deviation value, the first clamping force deviation value, and the deviation duration value. The second deviation reference parameter is determined by combining the second movement deviation value and the second clamping force deviation value; The second deviation reference parameter is adjusted based on the first deviation adjustment coefficient to determine the comprehensive deviation reference parameter, which is then used as the assembly reference parameter.

[0017] By adopting the above technical solution, the movement deviation, clamping force deviation, and deviation duration corresponding to the first clamping deviation parameter, as well as the movement deviation and clamping force deviation corresponding to the second clamping deviation parameter, are retrieved respectively. The first deviation adjustment coefficient and the second deviation reference parameter are constructed respectively. The comprehensive deviation reference parameter is obtained by coefficient correction and used as the assembly reference parameter. This makes the assembly reference parameter fit the actual assembly working conditions, improves the accuracy of subsequent assembly inspection and judgment, and weakens the interference of assembly deviation on the quality judgment of finished products.

[0018] Optionally, the method for determining the first deviation adjustment factor includes: Calculate the ratio between the spring diameter and the spring length and use it as the length-to-diameter ratio. Determine the reference range for the movement deviation based on the length-to-diameter ratio; Based on whether the first moving deviation value falls within the moving deviation reference range, the moving single coefficient is determined; The single coefficient of clamping force is determined by combining the first clamping force deviation value and the deviation duration value; A comprehensive coefficient is determined by combining the single coefficient of movement and the single coefficient of clamping force, and this comprehensive coefficient is used as the first deviation adjustment coefficient.

[0019] By adopting the above technical solution, the length-to-diameter ratio of the spring is calculated to define the reference range of the movement deviation. The movement single coefficient is obtained by matching the first movement deviation value. The clamping force single coefficient is obtained by combining the clamping force deviation value and the deviation duration. The first deviation adjustment coefficient is obtained by coupling calculation, which improves the pertinence of spring clamping deviation correction and makes the subsequent adjustment of the second deviation reference parameter more in line with the actual working conditions of spring pre-installation.

[0020] Optionally, the methods for determining the second deviation reference parameter include: The reference range of the moving clamping force is determined based on the second moving deviation value; Determine whether the second clamping force deviation value falls within the range of the moving clamping force reference; If so, the moving deviation reference parameter is determined based on the second moving deviation value, and the moving deviation reference parameter is used as the second deviation reference parameter; If not, calculate the deviation between the second clamping force deviation value and the moving clamping force reference range and use it as the clamping force abnormal deviation value; The abnormal clamping force reference parameter is determined based on the abnormal clamping force deviation value, and the abnormal clamping force reference parameter is used as the second deviation reference parameter.

[0021] By adopting the above technical solution, by setting the reference range of the moving clamping force, the working conditions of normal deviation and abnormal deviation are distinguished according to the range in which the second clamping force deviation value falls, and the corresponding reference parameters are matched to determine the second deviation reference parameters. For different deviation types, the corresponding reference calculation logic is adopted to improve the rationality and accuracy of the second deviation reference parameters and ensure the stability and reliability of the assembly reference parameters.

[0022] Optionally, methods for determining material feeding control information include: Determine whether the assembly inspection parameters meet the assembly datum parameters; If so, the preset material clamping information will be output and used as material feeding control information; If not, the assembly deviation value is determined based on the comparison between the assembly reference parameters and the assembly inspection parameters. The clamping adjustment information is determined based on the assembly deviation value, and the clamping adjustment information is combined with the preset interval feeding control information as the unloading control information.

[0023] By adopting the above technical solution, by comparing the assembly reference parameters and the assembly inspection parameters, the material unloading control information is output according to the parameter matching status difference. Material unloading operation is performed on qualified workpieces, and pressure adjustment and interval feeding combination control information is output for workpieces with assembly deviations. This realizes the automated judgment of the quality of the assembled finished product and the adaptive control of abnormal assembly conditions. On the basis of ensuring the efficient unloading of qualified workpieces, the abnormal assembly process is optimized and adjusted, thereby improving the finished product qualification rate of batch production and the stability of continuous equipment operation.

[0024] Secondly, the present invention provides an automatic assembly device for a synchronizer slider, which adopts the following technical solution: An automatic assembly device for a synchronizer slider, employing an automatic assembly method for a synchronizer slider as described in any one of the first aspects, comprises: a placement platform, a first feeding device for feeding the slider body, a second feeding device for feeding the spring, a first clamping device for clamping the spring, a third feeding device for feeding steel balls, a second clamping device for clamping the steel balls, an assembly detection device, and a unloading device. The placement platform is provided with a rotating disk, and the rotating disk is provided with a plurality of assembly placement parts for placing the slider body. The first feeding device, the second feeding device, the first pressing device, the third feeding device, the second pressing device, the assembly detection device and the unloading device are arranged sequentially around the rotating disk. The placement platform is equipped with a feeding pipe for feeding materials, and a feeding box is placed below the placement platform.

[0025] By adopting the above technical solution and using a rotary table workstation layout, the first feeding device, the second feeding device, the first pressing device, the third feeding device, the second pressing device, the assembly and inspection device, and the unloading device are sequentially arranged around the rotary table. The workpieces are carried by the assembly placement parts, and finished products are collected by the unloading pipe and the unloading box. This realizes the integrated automated operation of synchronous slider feeding, pressing, inspection, and unloading. The workstation layout is neat, the process connection is smooth, the manual intervention is reduced, the manual assembly error is reduced, the assembly operation efficiency is effectively improved, and it is suitable for the needs of large-scale mass production.

[0026] In summary, the present invention has at least one of the following beneficial technical effects: 1. The specifications of the slider body, spring, and steel ball are collected sequentially through the first, second, and third feeding end signals. The first and second clamping control information are generated step by step, and two-level clamping detection is completed. Then, the assembly reference parameters are determined and the unloading control information is generated in combination with the collected assembly detection parameters to control the operation of the unloading device. This realizes the full-process automation and parameterized control of the synchronizer slider assembly, improves the adaptability of different specification parts assembly, reduces the slippage of springs and steel balls during assembly, and improves the assembly efficiency of synchronizer slider. 2. After the clamping test is completed, the clamping test information is compared with the corresponding clamping control information in real time. For working conditions with deviations, the first clamping deviation parameter and the second clamping deviation parameter are identified respectively. The corresponding clamping adjustment information is generated and combined with the reset control information to complete the mechanism reset correction. This realizes real-time self-inspection, deviation identification and dynamic correction of the two-level clamping process, timely compensation for clamping deviations in the assembly process, reducing the probability of assembly defects, improving the pass rate of each pre-assembly process, and ensuring the smooth progress of the subsequent assembly process. 3. By comparing assembly reference parameters with assembly inspection parameters, the system outputs material unloading control information based on the differences in parameter matching status. For workpieces that meet the standards, the system performs unloading operations. For workpieces with assembly deviations, the system outputs a combination of clamping adjustment and interval feeding control information. This enables automated judgment of the quality of assembled finished products and adaptive control of abnormal assembly conditions. While ensuring efficient unloading of qualified workpieces, the system optimizes and adjusts abnormal assembly processes, thereby improving the finished product qualification rate of batch production and the stability of continuous equipment operation.

A rotating column is rotatably mounted on the reversing mechanism. The rotating column has a spring release groove for placing the spring. Through the reciprocating rotation of the rotating column, the spring release groove on the rotating column reciprocates towards the transport direction of the vibratory disk and the clamping direction of the second clamping mechanism, thereby facilitating the feeding of the spring. The first pressing device 4 includes a first pressing member for pressing the spring and a first moving mechanism for driving the pressing member to move vertically.

[0092] Among them, the steel ball pressing force refers to the target pressure value that the second pressing device 6 needs to apply to the steel ball to overcome the interference resistance and press the steel ball into the groove to reach the expected assembly position during the steel ball pressing process.

[0093] By combining the analysis of the steel ball mass, steel ball diameter, and groove diameter, the required clamping force of the steel ball is determined. The required clamping force of the steel ball is then combined with the required clamping depth of the assembly as the second clamping control information, thereby improving the accuracy of the obtained second clamping control information.

[0094] To further ensure the rationality of the steel ball clamping force requirement, it is necessary to conduct a further separate analysis and calculation of the steel ball clamping force requirement, which will be explained in detail through the steps shown below.

[0095] The method for determining the required clamping force of steel balls includes the following steps: S400: Calculate the ratio between the diameter of the steel ball and the diameter of the groove and use it as the interference ratio.

[0096] The interference ratio refers to the ratio between the diameter of the steel ball and the diameter of the groove.

[0100] By inputting the interference ratio value into a preset interference force database, the required interference clamping force can be matched, which facilitates subsequent use.

[0101] The larger the interference ratio, the greater the interference tightening force required. The interference force database pre-stores a lookup table of different interference ratio ranges and their corresponding interference tightening force requirements. The interference force database is obtained by the operator conducting tightening tests on different interference ratio values ​​and collecting the interference tightening force requirements in advance.

[0102] S402: Determine the required force for mass adjustment by combining elastic parameters and the mass of the steel ball.

[0103] Among them, the quality adjustment demand force refers to the influence of the steel ball's own quality characteristics and the spring's elasticity characteristics on the steel ball pressing process.

[0104] The larger the elastic parameter, the larger the mass of the steel ball, and the greater the corresponding mass adjustment force required. The product of the elastic parameter, the mass of the steel ball, and the preset inertia adjustment coefficient is calculated, and the result is used as the mass adjustment force for convenient subsequent use.

[0105] The inertia adjustment factor is a proportional factor used to convert the influence of mass on pressing force into force units. The inertia adjustment factor is preset by the operator based on the dynamic characteristics of the equipment and process experience.

[0106] S403: Calculate the ratio between the mass adjustment demand force and the interference clamping demand force and use it as the demand force ratio.

[0107] The demand force ratio refers to the ratio between the demand force for quality adjustment and the demand force for interference compression.

[0108] Calculating the demand ratio facilitates subsequent use.

[0109] S404: Determine whether the demand ratio is less than the preset demand baseline ratio. If yes, proceed to S405; if no, proceed to S406.

[0110] The demand force benchmark ratio refers to the benchmark ratio value at which no further adjustment of the interference clamping demand force is required. This benchmark ratio value is preset by the operator.

[0111] By judging whether the demand force ratio is less than the preset demand force benchmark ratio, it can be determined whether further adjustment of the interference compression demand force is needed.

[0112] S405: Use the interference clamping force as the steel ball clamping force.

[0113] When the required force ratio is less than the preset required force benchmark ratio, it means that no further adjustment of the interference clamping required force is needed. Therefore, the interference clamping required force is taken as the steel ball clamping required force.

[0114] S406: Determine the proportional adjustment coefficient based on the demand force ratio.

[0115] The proportional adjustment coefficient refers to the adjustment coefficient used to compensate for the excessive proportion of the quality adjustment demand force relative to the interference clamping demand force, which requires additional pressure.

[0116] When the required force ratio is not less than the preset required force benchmark ratio, it indicates that the interference clamping required force needs to be further adjusted. Therefore, the difference between the required force ratio and the required force benchmark ratio is calculated, and then the ratio between the difference and the required force benchmark ratio is calculated and used as the ratio deviation value. Then, the ratio deviation value is used as the ratio adjustment coefficient for convenient subsequent use.

[0117] S407: Calculate the product of the proportional adjustment coefficient and the interference clamping force and use it as the steel ball clamping force.

[0118] Specifically, the accuracy of the obtained steel ball clamping force is improved by calculating the product between the proportional adjustment coefficient and the interference clamping force, and using the calculation result as the steel ball clamping force.

[0119] To further ensure the rationality of collecting the first or second clamping detection information, it is necessary to perform further separate analysis and calculation after collecting the first or second clamping detection information. The specific steps are explained in detail below.

[0120] Reference Figure 3After collecting the first or second clamping detection information, the following steps are also included: S500: Determine whether the first clamping detection information is consistent with the first clamping control information or determine whether the second clamping detection information is consistent with the second clamping control information.

[0121] Specifically, by judging whether the first pressing detection information is consistent with the first pressing control information or whether the second pressing detection information is consistent with the second pressing control information, it is determined whether the execution result of each pressing link meets the control requirements.

[0122] S501: If all are consistent, continue to collect the steel ball specifications or determine the assembly reference parameters.

[0123] When the first clamping detection information is consistent with the first clamping control information and the second clamping detection information is consistent with the second clamping control information, it indicates that the execution results of each clamping step meet the control requirements. Therefore, the process of collecting steel ball specifications or determining assembly reference parameters continues.

[0124] S502: If there is an inconsistency, when the first clamping detection information and the first clamping control information are inconsistent, the first clamping deviation parameter shall be determined based on the comparison result between the first clamping detection information and the first clamping control information.

Therefore, the movement value and clamping force in the first clamping detection information are retrieved, and the movement value and clamping force in the first clamping control information are also retrieved. The difference is then calculated to obtain the first movement deviation value and the first clamping force deviation value. The duration corresponding to the first clamping force deviation value is collected and used as the deviation duration value. Finally, the first clamping deviation parameters are obtained for subsequent use.

The first movement deviation value is inverted and multiplied by a preset movement compensation coefficient to obtain the first clamping compensation movement amount. The first clamping force deviation value is inverted and multiplied by a preset force compensation coefficient to obtain the first clamping compensation force value. The deviation duration value is then divided by a preset time normalization coefficient to obtain the first clamping correction duration. Finally, the first clamping compensation movement amount, the first clamping compensation force value, and the first clamping correction duration are summarized and used as the first clamping adjustment information for convenient subsequent use.

[0130] The motion compensation coefficient, force compensation coefficient, and time normalization coefficient are preset by the operator based on the equipment response characteristics.

[0134] S505: When the second clamping detection information is inconsistent with the second clamping control information, the second clamping deviation parameter is determined based on the comparison result between the second clamping detection information and the second clamping control information.

[0135] When the second clamping detection information and the second clamping control information are inconsistent, it indicates that the execution result of the second clamping link does not meet the control requirements. Therefore, the movement value and clamping force in the second clamping detection information are retrieved, and the movement value and clamping force in the second clamping control information are retrieved. The difference is then calculated to obtain the second movement deviation value and the second clamping force deviation value. Finally, the two values ​​are summarized to obtain the second clamping deviation parameter for subsequent use.

[0136] S506: Determine the second clamping adjustment information based on the second clamping deviation parameter.

[0137] The second clamping adjustment information refers to the set of instruction parameters used to correct the subsequent actions of the second clamping device 6.

[0138] The second movement deviation value and the second clamping force deviation value are extracted from the second clamping deviation parameter. The second movement deviation value is inverted and multiplied by a preset movement compensation coefficient to obtain the calculation result as the second clamping compensation movement amount. The second clamping force deviation value is inverted and multiplied by a preset force compensation coefficient to obtain the product as the second clamping compensation force value. Then, the second clamping compensation movement amount and the second clamping compensation force value are summarized and used as the second clamping adjustment information for convenient subsequent use.

[0139] S507: Based on the combination of the second clamping adjustment information and the preset reset control information, and using it as the second clamping reset information, execute the second clamping reset information.

[0140] Specifically, the second clamping adjustment information is combined with the preset reset control information, and the combined control command is used as the second clamping reset information, and then the second clamping reset information is executed.

[0141] To further ensure the rationality of the assembly datum parameters, it is necessary to perform further separate analysis and calculation on the assembly datum parameters, which will be explained in detail through the steps shown below.

[0142] The method for determining assembly datum parameters includes the following steps: S600: Retrieve the first movement deviation value, the first clamping force deviation value, and the deviation duration value based on the first clamping deviation parameter; retrieve the second movement deviation value and the second clamping force deviation value based on the second clamping deviation parameter.

[0143] The first movement deviation value reflects the degree of deviation of the stroke of the first clamping element in the spring clamping stage. The first clamping force deviation value reflects the degree of deviation of the force applied by the first clamping element in the spring clamping stage. The deviation duration value refers to the duration corresponding to the first clamping force deviation value. The second movement deviation value reflects the degree of deviation of the stroke of the second clamping element in the steel ball clamping stage. The second clamping force deviation value reflects the degree of deviation of the force applied by the second clamping element in the steel ball clamping stage. The first clamping deviation parameter includes the first movement deviation value, the first clamping force deviation value, and the deviation duration value; the second clamping deviation parameter includes the second movement deviation value and the second clamping force deviation value.

[0144] The first movement deviation value, the first clamping force deviation value, the deviation duration value, the second movement deviation value, and the second clamping force deviation value are retrieved from the first clamping deviation parameter and the second clamping deviation parameter, respectively, which facilitates subsequent use.

[0145] S601: Determine the first deviation adjustment coefficient by combining the first movement deviation value, the first clamping force deviation value, and the deviation duration value.

[0146] Among them, the first deviation adjustment coefficient refers to the weight of the influence of the overall deviation of the quantified spring clamping link on the subsequent assembly reference parameters.

[0147] By combining and analyzing the first movement deviation value, the first clamping force deviation value, and the deviation duration value, the first deviation adjustment coefficient is determined to facilitate subsequent use.

[0148] S602: Determine the second deviation reference parameter by combining the second movement deviation value and the second clamping force deviation value.

[0149] The second deviation reference parameter refers to the reference parameter used to characterize the overall deviation of the steel ball pressing process.

[0150] By combining and analyzing the second movement deviation value and the second clamping force deviation value, the second deviation reference parameter is determined to facilitate subsequent use.

[0151] S603: Adjust the second deviation reference parameter according to the first deviation adjustment coefficient, determine the deviation comprehensive reference parameter, and use the deviation comprehensive reference parameter as the assembly reference parameter.

[0152] Among them, the deviation comprehensive reference parameter refers to the reference parameter corresponding to the deviation generated in the overall process of spring clamping and steel ball pressing.

[0153] By calculating the product between the first deviation adjustment coefficient and the second deviation reference parameter, and using the calculation result as the comprehensive deviation reference parameter, and then using the comprehensive deviation reference parameter as the assembly reference parameter, the accuracy of the obtained assembly reference parameter is improved.

[0154] To further ensure the rationality of the first deviation adjustment factor, it is necessary to perform a further separate analysis and calculation on the first deviation adjustment factor, which will be explained in detail through the steps shown below.

[0155] The method for determining the first deviation adjustment factor includes the following steps: S700: Calculate the ratio between the spring diameter and the spring length and use it as the length-to-diameter ratio.

[0156] The length-to-diameter ratio refers to the ratio between the spring diameter and the spring length.

[0157] Calculating the length-to-diameter ratio facilitates subsequent use.

[0158] S701: Determine the reference range for movement deviation based on the length-to-diameter ratio.

[0159] The moving deviation reference range refers to the reference range corresponding to the first moving deviation value under normal circumstances.

[0160] A larger length-to-diameter ratio results in better radial stability of the spring, a narrower range of displacement tolerances, and a smaller corresponding value. Conversely, a smaller length-to-diameter ratio results in poorer radial stability, a wider range of displacement tolerances, and a larger corresponding value. The displacement tolerance range is obtained by inputting the length-to-diameter ratio into a preset length-to-diameter reference database for convenient subsequent use.

[0161] The major diameter reference database has a pre-stored table of different major diameter ratios and their corresponding movement deviation reference ranges. The major diameter reference database is obtained after the operator pre-inputs the data.

[0162] For example, when the length-to-diameter ratio is ≤0.6, the corresponding range of movement deviation is ±0.10mm; when the length-to-diameter ratio is between 0.6 and 0.8, the corresponding range of movement deviation is ±0.08mm; and when the length-to-diameter ratio is >0.8, the corresponding range of movement deviation is ±0.05mm.

[0163] S702: Determine the single moving coefficient based on whether the first moving deviation value falls within the moving deviation reference range.

[0164] Among them, the single moving coefficient refers to the parameter that quantifies the contribution of the stroke deviation in the spring clamping link to the overall deviation adjustment coefficient.

[0165] By analyzing whether the first moving deviation value falls within the moving deviation reference range, when the first moving deviation value falls within the moving deviation reference range, 1 is used as the moving single coefficient. When the first moving deviation value does not fall within the moving deviation reference range, the nearest value between the first moving deviation value and the moving deviation reference range is selected as the nearest value. The ratio between the first moving deviation value and the nearest value is then used as the moving single coefficient for convenient subsequent use.

[0166] S703: Determine the single coefficient of clamping force by combining the first clamping force deviation value and the deviation duration value.

[0167] Among them, the clamping force single coefficient refers to the parameter that quantifies the contribution of force deviation in the spring clamping process to the overall deviation adjustment coefficient.

[0168] The product of the first clamping force deviation value and the deviation duration value is calculated and used as the cumulative deviation. The ratio between the cumulative deviation and the preset cumulative reference deviation value is used as the clamping force single coefficient for convenient subsequent use.

[0169] The cumulative reference deviation refers to the reference deviation corresponding to the force deviation that is allowed to exist under normal conditions. The cumulative reference deviation is obtained after being pre-input by the operator.

[0170] S704: Combine the single coefficient of movement and the single coefficient of clamping force to determine the comprehensive coefficient, and use the comprehensive coefficient as the first deviation adjustment coefficient.

[0171] Specifically, by weighting the single coefficient of movement and the single coefficient of clamping force, and using the result as a comprehensive coefficient, the accuracy of the obtained first deviation adjustment coefficient is improved. The specific weights for the weighted calculation are preset by the operator according to actual needs.

[0172] For example, the weight of the single coefficient of movement is 0.6, and the weight of the single coefficient of clamping force is 0.4. In this case, the comprehensive coefficient = single coefficient of movement * 0.6 + single coefficient of clamping force * 0.4.

[0173] To further ensure the rationality of the second deviation benchmark parameter, it is necessary to perform a further separate analysis and calculation on the second deviation benchmark parameter, which will be explained in detail through the steps shown below.

[0174] The method for determining the second deviation reference parameter includes the following steps: S800: Determine the reference range of the moving clamping force based on the second moving deviation value.

[0175] The moving clamping force reference range refers to the reference range corresponding to the clamping force deviation caused by the second moving deviation value.

[0176] The larger the second movement deviation value, the larger the corresponding value of the movement clamping force reference range. The movement clamping force reference range is obtained by inputting the second movement deviation value into the preset movement clamping force database for convenient subsequent use.

[0177] The mobile clamping force database has a pre-stored table of different second movement deviation values ​​and their corresponding mobile clamping force reference ranges. The mobile clamping force database is obtained after the operator pre-inputs the data.

[0178] S801: Determine whether the second clamping force deviation value falls within the moving clamping force reference range. If yes, proceed to S802; if no, proceed to S803.

[0179] Specifically, by judging whether the second clamping force deviation value falls within the range of the moving clamping force reference, it is determined whether the force deviation in the steel ball pressing process is determined by the stroke deviation.

[0180] S802: Determine the moving deviation reference parameter based on the second moving deviation value, and use the moving deviation reference parameter as the second deviation reference parameter.

[0181] Among them, the movement deviation reference parameter refers to the reference parameter that can be tolerated under normal assembly monitoring conditions based on the second movement deviation value.

[0182] When the second clamping force deviation value falls within the range of the moving clamping force reference, it indicates that the force deviation in the steel ball pressing process is determined by the stroke deviation. Therefore, by calculating the product between the second moving deviation value and the preset moving reference coefficient, and using the calculation result as the moving deviation reference parameter, and then using the moving deviation reference parameter as the second deviation reference parameter, the accuracy of the obtained second deviation reference parameter is improved.

[0183] The moving baseline coefficient is a coefficient used to convert the second moving deviation value into a moving deviation baseline parameter. The moving baseline coefficient is obtained after pre-entry by the operator.

[0184] S803: Calculate the deviation between the second clamping force deviation value and the moving clamping force reference range and use it as the clamping force abnormal deviation value.

[0185] Among them, the abnormal deviation value of the clamping force refers to the deviation value between the second clamping force deviation value and the moving clamping force reference range.

[0186] When the second clamping force deviation value does not fall within the range of the moving clamping force reference, it indicates that the force deviation in the steel ball pressing process is not only determined by the stroke deviation. Therefore, the abnormal clamping force deviation value is calculated for the convenience of subsequent use.

[0187] S804: Determine the abnormal clamping force reference parameter based on the abnormal clamping force deviation value, and use the abnormal clamping force reference parameter as the second deviation reference parameter.

[0188] Among them, the abnormal clamping force reference parameter refers to the reference parameter that can be tolerated under normal assembly monitoring conditions based on the abnormal deviation value of the clamping force.

[0189] The accuracy of the second deviation reference parameter is improved by calculating the product between the abnormal deviation value of the clamping force and the preset abnormal clamping force reference coefficient, and using the calculation result as the abnormal clamping force reference parameter. The abnormal clamping force reference parameter is then used as the second deviation reference parameter.

[0190] The clamping force anomaly reference coefficient is a coefficient used to convert the clamping force anomaly deviation value into a clamping force anomaly reference parameter. The clamping force anomaly reference coefficient is obtained after being pre-input by the operator.

[0191] To further ensure the rationality of the material feeding control information, it is necessary to perform further separate analysis and calculation on the material feeding control information, which will be explained in detail through the steps shown below.

[0192] Reference Figure 4The method for determining material feeding control information includes the following steps: S900: Determine whether the assembly inspection parameters meet the assembly reference parameters. If yes, execute S901; if no, execute S902.

[0193] Specifically, the actual moving distance and actual output pressure of the third clamping component are retrieved through assembly detection parameters. When the assembly reference parameter is the moving deviation reference parameter, the actual moving distance is compared with the moving deviation reference parameter. When the assembly reference parameter is the clamping force abnormality reference parameter, the actual output pressure is compared with the clamping force abnormality reference parameter. When the assembly detection parameter is less than the assembly reference parameter, it means that the assembly detection parameter meets the assembly reference parameter. When the assembly detection parameter is not less than the assembly reference parameter, it means that the assembly detection parameter does not meet the assembly reference parameter, thereby determining whether the material can be directly unloaded.

[0194] S901: Outputs preset feeding clamping information and uses it as feeding control information.

[0195] The material feeding clamping information refers to the set of instruction parameters used to drive the material feeding device 8 to perform standard material feeding actions. This information is obtained after being pre-input by the operator.

[0196] When the assembly reference parameters meet the assembly inspection parameters, it means that the material can be directly unloaded. Therefore, the preset unloading clamping information is output and used as the unloading control information.

[0197] S902: Determine the assembly deviation value based on the comparison between the assembly datum parameters and the assembly inspection parameters.

[0198] Among them, the assembly deviation value refers to the overall degree of deviation between the assembly reference parameters and the assembly inspection parameters.

[0199] When the assembly datum parameters do not meet the assembly inspection parameters, it means that the material cannot be cut directly. Therefore, the difference between the assembly datum parameters and the assembly inspection parameters is calculated, and the ratio between the difference and the assembly datum parameters is used as the assembly deviation value for subsequent use.

[0200] S903: Determine the clamping adjustment information based on the assembly deviation value, and combine the clamping adjustment information with the preset interval feeding control information as the unloading control information.

[0201] Among them, the clamping adjustment information refers to the set of parameters used to control the second clamping device 6 to rework and adjust products that fail to meet the clamping requirements. The interval feeding control information refers to the set of instruction parameters used to drive the first feeding device 2, the second feeding device 3, and the third feeding device 5 to pause feeding in the current feeding sequence.

[0202] By retrieving the required steel ball clamping force and assembly clamping depth from the second clamping control information, and then calculating the sum between the assembly deviation value and 1 as a comprehensive adjustment coefficient, the product of the comprehensive adjustment coefficient and the required steel ball clamping force and assembly clamping depth is calculated and used as the clamping adjustment required force and clamping adjustment depth. The clamping adjustment required force and clamping adjustment depth are then combined as clamping adjustment information. Finally, the clamping adjustment information is combined with the preset interval feeding control information as unloading control information, thereby improving the accuracy of the obtained unloading control information.
