[0022] Please refer to Figure 1 , Figure 1 The present invention is a flowchart of a gear shaft grinder workpiece clamping method based on dual servo drive in some embodiments of the present invention.

[0023] It should be noted that in order to realize the self-adjustment of workpiece clamping of the dual-servo driven gear shaft grinder, so as to improve the workpiece processing accuracy and quality, and when the workpiece processing quality deviates or fails to achieve the expected effect, the dual servo torque is adjusted to improve the processing quality and accuracy. First, the material characteristic data and physical property data of the workpiece to be processed are obtained, and the required tightening data are obtained by processing. The corresponding torque distribution ratio data is obtained by processing the performance data and installation position data corresponding to the dual servo motors respectively, and the transmission characteristic data is combined for processing to obtain the servo torque data corresponding to the dual servo motors.

[0024] Please refer to Figure 2 , Figure 2 The present invention is a flowchart of obtaining the required clamping data of the workpiece clamping method of the gear shaft grinder based on dual servo drive in some embodiments of the present application. According to the embodiment of the present invention, the material characteristic data and physical property data of the workpiece to be processed are obtained, and the workpiece texture machinability coefficient is obtained by processing, and the required clamping data of the workpiece to be processed is obtained by further processing, including: S21, obtaining material feature data and physical property data of the workpiece to be processed; S22, the material characteristic data includes original weight distribution data, original centroid distribution data, original size profile data and support contact area data; S23, the physical property data includes elastic modulus data and plastic hardness data; S24, processing the workpiece texture machinability coefficient according to the original component centroid distribution data, the original component size profile data and the support contact area data in combination with the elastic modulus data and the plastic hardness data; S25, processing the original weight distribution data in combination with the workpiece texture machinability coefficient to obtain required tightening data of the workpiece to be processed; The calculation formula of the workpiece texture machinability coefficient is: ; in, is the workpiece texture machinability coefficient, , , They are the original component centroid distribution data, original component size profile data, and support contact area data. , They are elastic modulus data and plastic hardness data respectively. , , , is a preset characteristic coefficient (the characteristic coefficient is obtained by querying a preset mechanical manufacturing information database); The calculation formula for the demand tightening data is: ; in, To meet the demand, , They are the original weight distribution data, the workpiece texture machinability coefficient, , It is the preset characteristic coefficient (the characteristic coefficient is obtained by querying the preset mechanical manufacturing information database).

[0025] It should be noted that before processing the workpiece, it is necessary to clamp the workpiece to be processed. In order to improve the clamping quality, it is necessary to first calculate the clamping data required for the workpiece to be processed. Therefore, the material characteristic data and physical property data of the workpiece to be processed are obtained, wherein the material characteristic data include the original weight distribution, the original center of mass distribution, the original size contour and the clamping contact area data, and the physical property data include the elastic modulus data and the plastic hardness data. The above data are processed to obtain the workpiece texture machinability coefficient, and further combined with the original weight distribution data for processing to obtain the required tightening data.

[0026] Please refer to Figure 3 , Figure 3The present invention is a flowchart of a method for obtaining torque distribution ratio data of a workpiece clamping method for a gear shaft grinder based on dual servo drive in some embodiments of the present invention. According to an embodiment of the present invention, the method of obtaining performance data and installation position data corresponding to the first and second servo motors, respectively, and processing to obtain torque distribution ratio data corresponding to the first and second servo motors includes: S31, obtaining performance data and installation position data corresponding to the No. 1 and No. 2 servo motors respectively; S32, the performance data includes rated power data, rated torque data, moment of inertia data and power factor; S33, performing processing according to the rated power data, the rated torque data, the moment of inertia data and the power factor to obtain a performance difference coefficient between the first and second servo motors; S34, the installation position data includes installation height data, installation angle data and installation reference surface data; S35, processing the installation height data, the installation angle data, and the installation reference plane data to obtain the installation position difference coefficient between the first and second servo motors; S36, performing processing according to the performance difference coefficient and the installation position difference coefficient to obtain torque distribution ratio data corresponding to the first servo motor and the second servo motor; The calculation formula of the torque distribution ratio data corresponding to the No. 1 servo motor is: ; in, The torque distribution ratio data corresponding to servo motor No. 1, , They are performance difference coefficient and installation position difference coefficient respectively. , , , is a preset characteristic coefficient (the characteristic coefficient is obtained by querying a preset mechanical manufacturing information database); The calculation formula of the torque distribution ratio data corresponding to the second servo motor is: ; in, The torque distribution ratio data corresponding to the second servo motor, This is the torque distribution ratio data corresponding to servo motor No. 1.

[0027] It should be noted that, since it is driven by dual servo motors, before calculating the servo torque of each of the dual servo motors, it is necessary to first obtain the torque distribution ratio data corresponding to the two motors. Therefore, it is necessary to obtain the performance difference coefficient and installation position difference coefficient between the dual servo motors, and process them to obtain the torque distribution ratio data corresponding to servo motors No. 1 and No. 2.

[0028] Please refer to Figure 4 , Figure 4 The present invention is a flowchart of a method for obtaining servo torque data of a workpiece clamping method for a gear shaft grinder based on dual servo drive in some embodiments of the present application. According to an embodiment of the present invention, the transmission characteristic data of the first and second servo motors are obtained, and the servo torque data corresponding to the first and second servo motors are obtained by processing the transmission characteristic data in combination with the required tightening data and the torque distribution ratio data, including: S41, acquiring transmission characteristic data of the first and second servo motors, including transmission ratio data and transmission efficiency data; S42, obtaining servo torque data corresponding to the first and second servo motors according to the transmission ratio data, the transmission efficiency data, and the required tightening data and the torque distribution ratio data; The calculation formula of the servo torque data corresponding to the No. 1 servo motor is: ; in, is the servo torque data corresponding to servo motor No. 1, , , , They are the transmission ratio data of servo motor No. 1, the transmission efficiency data of servo motor No. 1, the torque distribution ratio data corresponding to servo motor No. 1, and the required tightening data. is a preset characteristic coefficient (the characteristic coefficient is obtained by querying a preset mechanical manufacturing information database); The calculation formula of the servo torque data corresponding to the second servo motor is: ; in, is the servo torque data corresponding to the No. 2 servo motor, , , , They are the transmission ratio data of the No. 2 servo motor, the transmission efficiency data of the No. 2 servo motor, the torque distribution ratio data corresponding to the No. 2 servo motor, and the required tightening data. It is the preset characteristic coefficient (the characteristic coefficient is obtained by querying the preset mechanical manufacturing information database).

[0029] It should be noted that the servo torque provided by the dual servo motors corresponding to the tightening data required for the workpiece to be processed is not only affected by the torque distribution ratio, but also by the transmission characteristics of the motor itself. Therefore, it is necessary to first obtain the transmission characteristic data of servo motors No. 1 and No. 2, including transmission ratio data and transmission efficiency data, and process them in combination with the required tightening data and torque distribution ratio data to obtain the servo torque data corresponding to servo motors No. 1 and No. 2.

[0030] According to an embodiment of the present invention, the step of obtaining the working environment characteristic data corresponding to the processing of the n completed workpieces and processing to obtain the working environment correction factor includes: Acquire the working environment characteristic data corresponding to the processing of the n completed workpieces, including the vibration data and temperature data corresponding to the first and second servo motors; Processing the vibration data and the temperature data to obtain a working environment correction factor; The calculation formula of the working environment correction factor is: ; in, is the working environment correction factor corresponding to the processing of the i-th completed workpiece, , , , They are respectively the vibration data corresponding to the No. 1 servo motor, the vibration data corresponding to the No. 2 servo motor, the temperature data corresponding to the No. 1 servo motor, and the temperature data corresponding to the No. 2 servo motor when the i-th finished workpiece among the n finished workpieces is processed. , , , , It is the preset characteristic coefficient (the characteristic coefficient is obtained by querying the preset mechanical manufacturing information database).

[0031] It should be noted that during the machining process of the workpiece, the servo motor will vibrate and the equipment will generate heat. These factors will have a certain impact on the machining quality. Therefore, it is necessary to obtain the vibration and temperature data corresponding to the dual servo motors and process them to obtain the working environment correction factor.

[0032] According to an embodiment of the present invention, the obtaining of the precision feature data corresponding to the n finished workpieces, processing to obtain the corresponding machining quality effectiveness index, and respectively processing with the standard machining quality effectiveness index to obtain the corresponding machining quality deviation coefficient includes: Acquire the precision feature data corresponding to the n finished workpieces, including dimensional accuracy data, surface roughness data, and coaxiality data; Processing the dimensional accuracy data, surface roughness data and coaxiality data to obtain machining quality effectiveness indexes corresponding to the n finished workpieces; The machining quality effectiveness indexes corresponding to the n finished workpieces are processed one by one with the standard machining quality effectiveness index to obtain the corresponding machining quality deviation coefficient.

[0033] It should be noted that, after the n workpieces to be processed are clamped and processed according to the corresponding acquired required tightening data and servo torque data, and the corresponding n finished workpieces are obtained, the processing quality needs to be inspected. Therefore, it is necessary to collect the precision characteristic data of the n finished workpieces, including dimensional accuracy data, surface roughness data and coaxiality data, and process the above data to obtain the corresponding processing quality effectiveness index, and process them with the standard processing quality effectiveness index to obtain the corresponding processing quality deviation coefficient.

[0034] According to an embodiment of the present invention, the required tightening data, the servo torque data and the working environment correction factor corresponding to the n finished workpieces are processed in combination with the processing quality deviation coefficient to obtain a processing quality correction index, including: According to the required tightening data, the servo torque data and the working environment correction factor corresponding to the n completed workpieces, combined with the processing quality deviation coefficient, a processing quality correction index is obtained by processing through a preset workpiece processing quality inspection model; The calculation formula of the processing quality correction index is: ; in, is the processing quality correction index, , , , , They are the required tightening data of the i-th finished workpiece among n finished workpieces, the servo torque data corresponding to the No. 1 servo motor, the servo torque data corresponding to the No. 2 servo motor, the working environment correction factor, and the processing quality deviation coefficient. , It is the preset characteristic coefficient (the characteristic coefficient is obtained by querying the preset mechanical manufacturing information database).

[0035] It should be noted that in order to determine whether the finished workpiece obtained according to the clamping and processing method in the plan reaches the expected processing quality, it is necessary to process the required clamping data, servo torque data and working environment correction factor corresponding to the n finished workpieces in combination with the processing quality deviation coefficient through the calculation formula of the preset workpiece processing quality inspection model to obtain the processing quality correction index.

[0039] It should be noted that before processing the workpiece, it is necessary to clamp the workpiece to be processed. In order to improve the clamping quality, it is necessary to first calculate the clamping data required for the workpiece to be processed. Therefore, the material characteristic data and physical property data of the workpiece to be processed are obtained, wherein the material characteristic data include the original weight distribution, the original center of mass distribution, the original size contour and the clamping contact area data, and the physical property data include the elastic modulus data and the plastic hardness data.

[0041] It should be noted that, since it is driven by dual servo motors, before calculating the servo torque of each of the dual servo motors, it is necessary to first obtain the torque distribution ratio data corresponding to the two motors. Therefore, it is necessary to obtain the performance difference coefficient and installation position difference coefficient between the dual servo motors, and process them to obtain the torque distribution ratio data corresponding to servo motors No. 1 and No. 2.

[0042] According to an embodiment of the present invention, the transmission characteristic data of the first and second servo motors are acquired, and the required tightening data and the torque distribution ratio data are processed to obtain the servo torque data corresponding to the first and second servo motors, including: Acquire transmission characteristic data of the first and second servo motors, including transmission ratio data and transmission efficiency data; According to the transmission ratio data and the transmission efficiency data, and in combination with the required tightening data and the torque distribution ratio data, the servo torque data corresponding to the first and second servo motors are obtained; The calculation formula of the servo torque data corresponding to the No. 1 servo motor is: ; in, is the servo torque data corresponding to servo motor No. 1, , , , They are the transmission ratio data of servo motor No. 1, the transmission efficiency data of servo motor No. 1, the torque distribution ratio data corresponding to servo motor No. 1, and the required tightening data. is a preset characteristic coefficient (the characteristic coefficient is obtained by querying a preset mechanical manufacturing information database); The calculation formula of the servo torque data corresponding to the second servo motor is: ; in, is the servo torque data corresponding to the No. 2 servo motor, , , , They are the transmission ratio data of the No. 2 servo motor, the transmission efficiency data of the No. 2 servo motor, the torque distribution ratio data corresponding to the No. 2 servo motor, and the required tightening data.

[0043] It should be noted that the servo torque provided by the dual servo motors corresponding to the tightening data required for the workpiece to be processed is not only affected by the torque distribution ratio, but also by the transmission characteristics of the motor itself. Therefore, it is necessary to first obtain the transmission characteristic data of servo motors No. 1 and No. 2, including transmission ratio data and transmission efficiency data, and process them in combination with the required tightening data and torque distribution ratio data to obtain the servo torque data corresponding to servo motors No. 1 and No. 2.

[0047] It should be noted that, after the n workpieces to be processed are clamped and processed according to the corresponding acquired required tightening data and servo torque data, and the corresponding n finished workpieces are obtained, the processing quality needs to be inspected. Therefore, it is necessary to collect the precision characteristic data of the n finished workpieces, including dimensional accuracy data, surface roughness data and coaxiality data, and process the above data to obtain the corresponding processing quality effectiveness index, and process them with the standard processing quality effectiveness index to obtain the corresponding processing quality deviation coefficient.

[0049] It should be noted that in order to determine whether the finished workpiece obtained according to the clamping and processing method in the plan reaches the expected processing quality, it is necessary to process the required clamping data, servo torque data and working environment correction factor in combination with the processing quality deviation coefficient through the calculation formula of the preset workpiece processing quality inspection model to obtain the processing quality correction index.
