A control method, system and terminal for a high-precision grinding machine for an eccentric butterfly valve sealing pair Technical Field

[0001] This invention relates to the field of grinding technology, and in particular to a control method, system and terminal for a high-precision grinding machine with an eccentric butterfly valve sealing pair. Background Technology

[0002] A grinding machine is a machine tool that uses an abrasive wheel to grind the surface of a workpiece. Grinding machines use a grinding wheel as the main cutting tool and are used for precision machining of both metallic and non-metallic workpieces. This helps achieve high surface quality and dimensional accuracy, and therefore they are widely used in precision machining in industrial production.

[0003] The sealing pair of an eccentric butterfly valve refers to the key component used to achieve the sealing function, typically consisting of a valve seat and a valve plate (or sealing ring). During the manufacturing process of an eccentric butterfly valve, the machining accuracy of the sealing pair directly affects its sealing performance. To ensure the flatness, roughness, and dimensional accuracy of the sealing pair for a good sealing effect, high-precision grinding machines are generally used to precisely grind the sealing pair of the eccentric butterfly valve. A special positioning bevel plate, manufactured according to requirements, is installed in the high-precision grinding machine. The bevel plate and clamping tools hold and fix the valve seat or valve plate, causing it to rotate. During rotation, the grinding head in the high-precision grinding machine performs finishing on the valve seat or valve plate, thus precisely grinding the sealing pair of the eccentric butterfly valve.

[0004] When machining the sealing pair of an eccentric butterfly valve using a high-precision grinding machine, the operator needs to first manufacture and install a special positioning inclined plate according to the valve seat or valve plate to be machined before grinding. When machining eccentric butterfly valves of different specifications, the operator needs to manufacture the special positioning inclined plate multiple times, resulting in low overall machining efficiency of the sealing pair of the eccentric butterfly valve.

[0045] Among them, the regional distribution adjustment information refers to the adjustment information that needs to be adjusted based on the impact of the slope detection value on the regional distribution. This regional distribution adjustment information is obtained by querying a database that stores the correspondence between slope detection values ​​and regional distribution adjustment information. This database is obtained after the operator has pre-entered the information. Determining the regional distribution adjustment information through slope detection value query facilitates subsequent use.

[0046] Step S250: Adjust the initial specification pressure reference area information based on the regional distribution adjustment information to form reference distribution area information.

[0047] Among them, the reference distribution area information refers to the area where the pressure distribution of the eccentric butterfly valve needs to be located during normal processing. The reference distribution area information is adjusted by the area distribution adjustment information to form the reference distribution area information, which facilitates the subsequent use of the reference distribution area information.

[0049] Among them, the distribution area deviation information refers to the deviation information corresponding to the existence of deviation in the pressure distribution area. By analyzing the deviation between the pressure distribution area information and the reference distribution area information, the distribution area deviation information is used to facilitate subsequent use.

[0050] Step S270: Analyze and determine specification adjustment information based on the distribution area deviation information.

[0051] Among them, specification adjustment information refers to the adjustment information for adjusting the selected eccentric butterfly valve specifications. The specification adjustment information is determined by analyzing the deviation information of the distribution area, which facilitates subsequent use.

[0052] Step S280: Adjust the initial specification information of the eccentric butterfly valve based on the specification adjustment information to form the eccentric butterfly valve adjustment specification information, and use the eccentric butterfly valve adjustment specification information as the eccentric butterfly valve selection specification information.

[0053] Among them, the eccentric butterfly valve adjustment specification information refers to the specification information corresponding to the selected eccentric butterfly valve after adjustment. The initial specification information of the eccentric butterfly valve is adjusted according to the specification adjustment information to form the eccentric butterfly valve adjustment specification information. The eccentric butterfly valve adjustment specification information is used as the eccentric butterfly valve selection specification information to improve the accuracy of the obtained eccentric butterfly valve selection specification information.

[0054] In step S270 shown in Figure 2, in order to further ensure the rationality of the specification adjustment information, it is necessary to perform further separate analysis and calculation on the specification adjustment information, which will be explained in detail through the steps shown in Figure 3.

[0055] Referring to Figure 3, the method for determining specification adjustment information includes the following steps: Step S271: Based on the distribution area deviation information, retrieve the deviation area value and the deviation center position point corresponding to the deviation area value.

[0056] Among them, the deviation area value refers to the deviation value corresponding to the area deviation of each distribution area, and the deviation center location point refers to the location point at the center of the deviation area range when there is a deviation in each distribution area. The deviation area value and the deviation center location point can be retrieved through the distribution area deviation information for convenient subsequent use.

[0057] Step S272: Based on the correspondence between the initial specification pressure reference area information, the deviation center location point and the preset deviation location reference area value, determine the deviation location reference area value corresponding to the initial specification pressure reference area information and the deviation center location point.

[0059] Step S273: Determine whether the deviation area value is less than the reference area value at the deviation position. If yes, proceed to step S274; if no, proceed to step S275.

[0060] Specifically, by judging whether the deviation area value is less than the reference area value at the deviation position, it is determined that the initially selected specifications need to be adjusted.

[0061] Step S274: Output the preset baseline adjustment information and use it as specification adjustment information.

[0062] The baseline adjustment information refers to the adjustment information when no specification adjustment is required. This information is obtained after pre-input by the operator. When the deviation area value is less than the baseline area value at the deviation position, it indicates that no adjustment to the initially selected specification is needed. Therefore, the baseline adjustment information is output and used as the specification adjustment information.

[0064] Among them, the deviation area abnormal value refers to the deviation value when there is an abnormal deviation in the deviation area. When the deviation area value is not less than the reference area value of the deviation position, it means that the initially selected specifications need to be adjusted.

[0072] Among them, the comprehensive impact value of anomalies refers to the comprehensive impact on specification adjustments when anomalies occur in the area of ​​deviation. It is calculated by the sum of the impact values ​​of the number of anomalies and the impact values ​​of the area anomalies, and is used as the comprehensive impact value of anomalies for subsequent use.

[0073] Step S27A: Based on the correspondence between the comprehensive impact value of the anomaly and the preset comprehensive adjustment information of the anomaly, determine the comprehensive adjustment information of the anomaly corresponding to the comprehensive impact value of the anomaly, and use the comprehensive adjustment information of the anomaly as the specification adjustment information.

[0086] Step S2786: Calculate the comprehensive influence value of the deviation center based on the deviation center distance value, deviation center direction angle value, and deviation area anomaly value, and use the comprehensive influence value of the deviation center as the area anomaly influence value.

[0087] Among them, the comprehensive influence value of the deviation center refers to the comprehensive influence value generated by the center of the deviation area range. By analyzing the deviation center distance value, deviation center direction angle value and deviation area anomaly value, the comprehensive influence value of the deviation center is determined, and the comprehensive influence value of the deviation center is used as the area anomaly influence value to improve the accuracy of the obtained area anomaly influence value.

[0088] The analysis and calculation method of the comprehensive influence value of the deviation center includes: based on the calculation formula of the comprehensive influence value of the deviation center, analyzing and calculating the distance value of the deviation center, the direction angle value of the deviation center, and the abnormal value of the deviation area to obtain the comprehensive influence value of the deviation center.

[0089] The formula for calculating the comprehensive influence value of the deviation center is A=L*a+X*b+S*c; where A is the comprehensive influence value of the deviation center, L is the distance value of the deviation center, a is the baseline influence value corresponding to the preset distance value of the deviation center, X is the direction angle value of the deviation center, b is the baseline influence value corresponding to the preset direction angle value of the deviation center, S is the deviation area anomaly value, and c is the baseline influence value corresponding to the preset deviation area anomaly value.

[0090] In step S500 shown in Figure 1, in order to further ensure the rationality of the slope adjustment control information, it is necessary to perform further separate analysis and calculation on the slope adjustment control information, which will be explained in detail through the steps shown in Figure 5.

[0091] Referring to Figure 5, the method for determining the slope adjustment control information includes the following steps: Step S510: Determine whether the slope adjustment value is less than the preset slope adjustment reference value. If yes, proceed to step S520; if no, proceed to step S530.

[0092] The slope adjustment reference value refers to the maximum allowable adjustment value of the slope plate, which is obtained after being pre-input by the operator. The system determines whether the slope plate can be used for adjustment directly by checking if the adjustment value is less than the preset slope adjustment reference value.

[0093] Step S520: Based on the correspondence between the slope adjustment value and the preset slope plate individual adjustment information, determine the slope plate individual adjustment information corresponding to the slope adjustment value, and use the slope plate individual adjustment information as slope adjustment control information.

[0094] The individual slope adjustment information refers to the control information for individual slope adjustment. This information is obtained by querying a database that stores the correspondence between slope adjustment values ​​and individual slope adjustment information. This database is retrieved after pre-input by the operator. When the slope adjustment value is less than the preset slope adjustment reference value, it indicates that the slope can be directly adjusted using the slope. Therefore, the individual slope adjustment information is determined by querying the slope adjustment value and used as the slope adjustment control information, thus improving the accuracy of the obtained slope adjustment control information.

[0095] Step S530: Calculate the difference between the slope adjustment value and the slope adjustment reference value and use it as the slope adjustment deviation value.

[0096] The slope adjustment deviation value refers to the deviation value when there is a deviation in the slope adjustment. When the slope adjustment value is not less than the preset slope adjustment reference value, it means that the slope plate cannot be used directly for adjustment. Therefore, the difference between the slope adjustment value and the slope adjustment reference value is calculated and used as the slope adjustment deviation value for convenient subsequent use.

[0097] Step S540: Analyze the slope adjustment deviation value to determine the additional slope adjustment control information, and combine the additional slope adjustment control information with the preset slope plate reference adjustment information to form the slope adjustment control information.

[0098] The slope plate reference adjustment information refers to the control information used for maximum reference adjustment using the slope plate, which is obtained after pre-input by the operator. The additional slope adjustment control information refers to the control information corresponding to additional slope adjustments. This additional slope adjustment control information is determined by analyzing the slope adjustment deviation value. Combined with the additional slope adjustment control information and the slope plate reference adjustment information, the overall slope adjustment control information is formed, improving the accuracy of the obtained slope adjustment control information.

[0099] In step S540 shown in Figure 5, in order to further ensure the rationality of the slope additional adjustment control information, it is necessary to perform further separate analysis and calculation on the slope additional adjustment control information, which will be explained in detail in the steps shown in Figure 6.

[0100] Referring to Figure 6, the method for determining the additional adjustment control information of the slope includes the following steps: Step S541: Determine whether the slope adjustment deviation value is less than the preset grinding head reference slope value. If yes, proceed to step S542; if no, proceed to step S543.

[0101] The grinding head reference angle value refers to the maximum allowable angle adjustment value of the tool holder where the grinding head is located. The grinding head reference angle value is obtained after being pre-input by the operator. By judging whether the angle adjustment deviation value is less than the preset grinding head reference angle value, it is determined whether the angle can be further adjusted using only the grinding head.

[0102] Step S542: Based on the correspondence between the inclination adjustment deviation value and the preset grinding head adjustment control information, determine the grinding head adjustment control information corresponding to the inclination adjustment deviation value, and use the grinding head adjustment control information as additional inclination adjustment control information.

[0103] Among them, the grinding head adjustment control information refers to the control information for adjusting the angle of the grinding head. This information is obtained by querying a database that stores the correspondence between angle adjustment deviation values ​​and grinding head adjustment control information. This database is retrieved after pre-input by the operator. When the angle adjustment deviation value is less than the preset grinding head reference angle value, it indicates that the angle can be further adjusted using only the grinding head. Therefore, the grinding head adjustment control information is determined by querying the angle adjustment deviation value and used as additional angle adjustment control information, thus improving the accuracy of the obtained additional angle adjustment control information.

[0104] Step S543: Calculate the difference between the slope adjustment deviation value and the grinding head reference slope value and use it as the grinding head slope deviation value.

[0105] Among them, the grinding head slope deviation value refers to the deviation value of the slope adjustment when the grinding head is used to adjust the slope. When the slope adjustment deviation value is not less than the preset grinding head reference slope value, it means that the slope cannot be adjusted by the grinding head alone. Therefore, the difference between the slope adjustment deviation value and the grinding head reference slope value is calculated and used as the grinding head slope deviation value for subsequent use.

[0106] Step S544: Determine the additional angle supplement value corresponding to the grinding head angle deviation value based on the correspondence between the grinding head angle deviation value and the preset additional angle supplement value.

[0107] The additional draft compensation value refers to the height value corresponding to the additional draft required. This value is obtained by querying a database that stores the correspondence between grinding head draft deviation values ​​and additional draft compensation values. This database is retrieved after pre-entry by the operator. Determining the additional draft compensation value through the grinding head draft deviation value query facilitates subsequent use.

[0108] Step S545: Retrieve the reference area value of the selected specification based on the specification information of the eccentric butterfly valve.

[0109] The selected specification reference area value refers to the area value corresponding to the selected eccentric butterfly valve specification. The selected specification reference area value is retrieved through the eccentric butterfly valve specification selection information for convenient subsequent use.

[0110] Step S546: Based on the correspondence between the additional slope supplement value, the selected specification base area value and the preset slope supplement requirement specification information, determine the slope supplement requirement specification information corresponding to the additional slope supplement value and the selected specification base area value.

[0111] The slope supplementation requirement specification information refers to the specification information of the additional supplementary parts required when making additional adjustments. This information is obtained by querying a database that stores the correspondence between additional slope supplementation values, selected specification reference area values, and slope supplementation requirement specification information. This database is obtained after the operator has pre-entered the information. Determining the slope supplementation requirement specification information through querying the additional slope supplementation values ​​and selected specification reference area values ​​facilitates subsequent use.

[0112] Step S547: Retrieve the location points of the required specifications based on the slope supplementary requirement specification information.

[0113] The required specification location point refers to the location where the selected additional supplementary parts are stored. The required specification location point can be retrieved by supplementing the required specification information through slope, which is convenient for subsequent use.

[0114] Step S548: Based on the correspondence between the required specification location point and the preset required specification loading and unloading control information, determine the required specification loading and unloading control information corresponding to the required specification location point, and combine the required specification loading and unloading control information with the preset grinding head reference control information as additional tilt adjustment control information.

[0115] The required specification loading and unloading control information refers to the control information for controlling the robotic arm and other preset loading and unloading devices to pick up the selected additional supplementary parts and install them onto the high-precision grinding machine. This information is obtained by querying a database that stores the correspondence between the required specification location points and the required specification loading and unloading control information. This database is obtained after pre-input by the operator. The grinding head reference control information refers to the control information for adjusting the grinding head according to the grinding head reference slope value. This information is also obtained after pre-input by the operator.

[0116] The required specification loading and unloading control information is determined by querying the location point of the required specification, and then combined with the preset grinding head reference control information to serve as additional slope adjustment control information, thereby improving the accuracy of the obtained additional slope adjustment control information.

[0117] In step S600 shown in Figure 1, to further ensure the rationality of the grinding path information, it is necessary to perform further separate analysis and calculation on the grinding path information, which will be explained in detail below. The method for determining the grinding path information includes the following steps: Step S610: Based on the specification information of the eccentric butterfly valve, retrieve the specification grinding reference position point.

[0118] Among them, the specification grinding reference position point refers to the grinding reference position point corresponding to the selected specification and flat eccentric butterfly valve when grinding. The specification grinding reference position point can be retrieved by selecting the specification information of the eccentric butterfly valve for convenient subsequent use.

[0119] Step S620: Analyze and determine the influence value of the slope adjustment position based on the slope adjustment control information.

[0120] The slope adjustment position influence value refers to the impact of slope adjustment on position. By analyzing the slope adjustment control information, the slope adjustment position influence value is determined for subsequent use.

[0121] Step S630: Adjust the specification grinding reference position point based on the inclination adjustment position influence value to form the specification grinding adjustment position point.

[0122] Among them, the specification grinding adjustment position point refers to the position point after the grinding position is adjusted. The position of each specification grinding reference position point is adjusted by adjusting the position influence value of the slope adjustment, thereby forming the specification grinding adjustment position point for convenient subsequent use.

[0123] Step S640: Calculate the distance between the specification grinding adjustment position point and the preset grinding head reference position point and use it as the grinding adjustment position distance value.

[0124] The grinding head reference position point refers to the initial position of the grinding head before grinding, which is obtained through pre-input by the operator. The grinding adjustment position distance value refers to the distance between the adjusted grinding position and the grinding head position. It is calculated by the distance between the specified grinding adjustment position point and the grinding head reference position point and used as the grinding adjustment position distance value for convenient subsequent use.

[0125] Step S650: Sort the grinding adjustment position distance values ​​from smallest to largest, and combine the grinding adjustment position points corresponding to the sorted grinding adjustment position distance values ​​to form grinding adjustment path information, and use the grinding adjustment path information as grinding processing path information.

[0126] Among them, grinding adjustment path information refers to the path information formed after the adjusted grinding position is synthesized. The grinding adjustment position distance values ​​are sorted from smallest to largest, and the corresponding specification grinding adjustment position points are combined and the paths are synthesized according to the sorted grinding adjustment position distance values ​​to form grinding adjustment path information. The grinding adjustment path information is used as the grinding processing path information to improve the accuracy of the obtained grinding processing path information.

[0127] In step S620, to further ensure the rationality of the slope adjustment position influence value, it is necessary to perform a further separate analysis and calculation of the slope adjustment position influence value. This is explained in detail below. The method for determining the slope adjustment position influence value includes the following steps: Step S621: Determine whether the slope adjustment control information is slope plate adjustment information alone. If yes, proceed to step S622; if no, proceed to step S623.

[0128] Specifically, by judging whether the slope adjustment control information is a slope plate adjustment information alone, it can be determined whether only the slope plate needs to be adjusted.

[0129] Step S622: Based on the correspondence between the slope adjustment value and the preset slope adjustment individual influence value, determine the slope adjustment individual influence value corresponding to the slope adjustment value, and use the slope adjustment individual influence value as the slope adjustment position influence value.

[0130] Among them, the slope adjustment individual impact value refers to the degree of impact produced by the adjustment of the slope plate alone. The slope adjustment individual impact value is obtained by querying a database that stores the correspondence between slope adjustment values ​​and slope adjustment individual impact values. This database is obtained after the operator has pre-input.

[0131] When the slope adjustment control information is slope plate adjustment information only, it means that only the slope plate is adjusted at this time. Therefore, the slope adjustment individual influence value is determined by querying the slope adjustment value, and the slope adjustment individual influence value is used as the slope adjustment position influence value, thereby improving the accuracy of the obtained slope adjustment position influence value.

[0132] Step S623: Determine the slope supplementation influence value corresponding to the additional slope supplementation value based on the correspondence between the additional slope supplementation value and the preset slope supplementation influence value.

[0133] The slope compensation influence value refers to the degree of impact after the slope compensation component is installed. This value is obtained by querying a database that stores the correspondence between additional slope compensation values ​​and their corresponding slope compensation influence values. This database is retrieved after pre-entry by the operator. When the slope adjustment control information is not solely for adjusting the slope plate, it indicates that the slope plate is being adjusted in addition to the slope plate itself. Therefore, the slope compensation influence value is determined by querying the additional slope compensation value for convenient subsequent use.

[0134] Step S624: Calculate the sum between the slope supplement influence value and the preset slope adjustment benchmark influence value and use it as the slope adjustment comprehensive influence value, and use the slope adjustment comprehensive influence value as the slope adjustment position influence value.

[0135] The slope adjustment baseline influence value refers to the influence value generated after adjusting the slope plate according to the slope adjustment baseline value. The slope adjustment baseline influence value is obtained after being pre-input by the operator. The slope adjustment comprehensive influence value refers to the comprehensive influence value generated after slope adjustment. It is calculated by the sum of the slope supplementary influence value and the preset slope adjustment baseline influence value, and is used as the slope adjustment position influence value, thereby improving the accuracy of the obtained slope adjustment position influence value.
