Description

Technical Field

[0001] The present application relates to the field of mechanical processing equipment, and in particular to a grinding wheel life detection method, system, storage medium and intelligent terminal. Background Art

[0002] Grinding is a conventional parts processing method used to remove excess material from the workpiece. Grinding is extremely common in the processing of shaft parts.

[0003] In the related art, during the grinding process of shaft parts, two grinding wheels that are relatively arranged and rotate in opposite directions can grind the shaft parts to remove excess material on the shaft parts so that the radius size of the shaft parts meets the requirements.

[0004] With respect to the above-mentioned related technologies, the inventors believe that during the use of the grinding wheel, the grinding wheel itself will wear due to the existence of friction. When the grinding wheel is severely worn, the effect of processing shaft parts is poor, and it is possible that the shaft parts cannot meet the factory requirements. Therefore, it is necessary to detect the wear of the grinding wheel when processing shaft parts. Summary of the invention

[0005] In order to detect the wear of a grinding wheel, the present application provides a grinding wheel life detection method, system, storage medium and intelligent terminal.

[0006] In a first aspect, the present application provides a grinding wheel life detection method, which adopts the following technical solution:

[0007] A method for detecting the life of a grinding wheel, comprising:

[0008] Obtain the first hopper weight information and process trigger signal of the preset receiving hopper before part processing;

[0009] According to the process trigger signal, the preset grinding wheel operation is controlled for a preset fixed time, and the weight information of the second hopper of the receiving hopper is obtained after the operation is completed;

[0010] Determine the weight information of the debris based on the second hopper weight information and the first hopper weight information;

[0011] Determining whether the weight value corresponding to the debris weight information is within a preset debris range;

[0012] If the weight value corresponding to the chip weight information is not within the chip range, a grinding abnormality signal is output;

[0013] If the weight value corresponding to the chip weight information is within the chip range, a normal grinding signal is output.

[0014] By adopting the above technical scheme, the first hopper weight information and process trigger information of the receiving hopper before part processing are first obtained, and then the grinding wheel operation is controlled according to the process trigger information to grind the shaft parts. The material removed by the shaft parts processing is moved to the receiving hopper, so that after the shaft parts processing is completed, the weight of the receiving hopper can be re-tested to obtain the weight of the material removed by the shaft parts processing. By judging the weight, it can be determined whether the shaft parts are in a normal processing state, and the wear condition of the grinding wheel can be judged, so that the staff can know whether the grinding wheel can meet the grinding requirements.

[0015] Optionally, when the weight value corresponding to the chip weight information is not within the chip range, the grinding wheel life detection method further includes:

[0016] Divide the detection intervals with a width of a preset fixed value backward from the time when the process trigger signal is output on the preset time axis, and control the detection intervals to move in a positive sequence on the time axis;

[0017] Define the endpoint closer to the beginning of the detection interval as the initial point, and the endpoint closer to the end of the detection interval as the end point;

[0018] Obtain the initial weight information of the receiving hopper at the initial point and the final weight information of the receiving hopper at the final point;

[0019] Calculate and determine the change weight information based on the final weight information and the initial weight information;

[0020] Determine whether the weight value corresponding to the change weight information is greater than the preset mutation weight;

[0021] If the weight value corresponding to the changed weight information is greater than the sudden change weight, a foreign body entry signal is output;

[0022] If the weight value corresponding to the changed weight information is not greater than the sudden change weight, a grinding abnormality signal is output.

[0023] By adopting the above technical scheme and dividing the detection interval, it is possible to determine whether there is a sudden change in weight in the receiving hopper, thereby determining whether there is a foreign object entering the receiving hopper so that the weight change of the receiving hopper is inconsistent with the weight change of the receiving hopper during normal processing of shaft parts, so as to reduce the occurrence of inconsistent detection of grinding wheel wear caused by foreign objects entering the receiving hopper.

[0024] Optionally, after the foreign matter entry signal is output, the grinding wheel life detection method further includes:

[0025] The end point at this time is defined as a mutation point, and the position on the time axis that is a preset unit value away from the mutation point is defined as a normal point and a stable point, and the normal point is located before the stable point on the time axis;

[0026] Obtain normal weight information of the receiving hopper at a normal point and stable weight information of the receiving hopper at a stable point;

[0027] Determine the weight information of the foreign matter based on the calculation of the stable weight information and the normal weight information;

[0028] The actual chip weight information is determined by calculation based on the chip weight information and the foreign matter weight information;

[0029] Determine whether the weight value corresponding to the actual chip weight information is within the chip range;

[0030] If the weight value corresponding to the actual chip weight information is within the chip range, a normal grinding signal is output;

[0031] If the weight value corresponding to the actual chip block weight information is not within the chip range, a grinding abnormality signal is output.

[0032] By adopting the above technical solution, the situation of foreign matter entering the hopper can be further analyzed to determine whether the weight of the debris generated is the weight generated during the normal processing of shaft parts, so as to eliminate the interference caused by foreign matter and improve the accuracy of judging the wear condition of the grinding wheel.

[0033] Optionally, a method for determining the weight information of the foreign matter is also included, the method comprising:

[0034] The changed weight information of the first detection interval is defined as the standard weight information;

[0035] Determine the time ratio based on fixed value and unit value;

[0036] According to the time proportion ratio and the standard weight information, the weight information of the chips entering the bucket between the normal point and the stable point is determined;

[0037] The foreign matter weight information is determined by calculation based on the stable weight information, the normal weight information and the bucket weight information, wherein the foreign matter weight information is the difference between the stable weight information and the bucket weight information.

[0038] By adopting the above technical solution, the weight of the foreign matter can be further accurately measured, thereby improving the accuracy of the detection of the degree of wear of the grinding wheel.

[0039] Optionally, after the grinding abnormality signal is output, the grinding wheel life detection method further includes:

[0040] Obtain the processing length information of shaft parts, abnormal area information of grinding wheels, and invalid area information;

[0041] Determine the standby area information according to the abnormal area information, the invalid area information and the preset working area of ​​the grinding wheel;

[0042] Determine whether the area length corresponding to the standby area information is greater than the length corresponding to the processing length information;

[0043] If the area length corresponding to the standby area information is not greater than the length corresponding to the processing length information, an invalid signal is output, and the current grinding wheel is controlled to exchange positions with the preset standby grinding wheel;

[0044] If the area length corresponding to the standby area information is greater than the length corresponding to the processing length information, a valid signal is output.

[0045] By adopting the above technical solution, it is possible to judge whether the remaining area of ​​the grinding wheel can meet the current processing of shaft parts, so as to determine whether the grinding wheel needs to be replaced.

[0046] Optionally, before and after the current grinding wheel is swapped with the spare grinding wheel, the grinding wheel life detection method further includes:

[0047] Get the usage area information of spare grinding wheels;

[0048] Determine whether the area length corresponding to the use area information is greater than the length corresponding to the processing length information;

[0049] If the area length corresponding to the use area information is greater than the length corresponding to the processing length information, the current grinding wheel and the spare grinding wheel are controlled to exchange positions, and a valid signal is output;

[0050] If the area length corresponding to the use area information is not greater than the length corresponding to the processing length information, a standby invalid signal is output.

[0051] By adopting the above technical solution, it is possible to judge whether the spare grinding wheel meets the processing requirements, so that the grinding wheel that can meet the processing requirements can be replaced.

[0052] Optionally, after the effective signal is output, the grinding wheel life detection method further includes:

[0053] Obtaining boundary line information of an area corresponding to the abnormal area information and an area corresponding to the standby area information;

[0054] Controlling the grinding wheel to move along a preset fixed direction and determining whether the boundary line corresponding to the boundary line information coincides with the preset operation line;

[0055] If the boundary line corresponding to the boundary line information does not coincide with the working line, the grinding wheel is controlled to continue to move and an adjustment signal is output;

[0056] If the boundary line corresponding to the boundary line information coincides with the working line, the grinding wheel is controlled to stop moving and an adjustment completion signal is output.

[0057] By adopting the above technical solution, the grinding wheel that meets the processing requirements can be moved to the corresponding position to continue processing the shaft parts.

[0058] In a second aspect, the present application provides a grinding wheel life detection system, which adopts the following technical solution:

[0059] A grinding wheel life detection system, comprising:

[0060] An acquisition module is used to obtain the weight information of the first hopper of the preset receiving hopper before the parts are processed and the process trigger signal;

[0061] A processing module, connected to the acquisition module and the judgment module, for storing and processing information;

[0062] The processing module controls the preset grinding wheel operation for a preset fixed time according to the process trigger signal, and obtains the weight information of the second hopper of the receiving hopper after the operation is completed;

[0063] The processing module calculates and determines the weight information of the debris according to the weight information of the second hopper and the weight information of the first hopper;

[0064] A judging module, used to judge whether the weight value corresponding to the debris weight information is within a preset debris range;

[0065] If the judging module determines that the weight value corresponding to the chip weight information is not within the chip range, the processing module outputs a grinding abnormality signal;

[0066] If the judging module determines that the weight value corresponding to the chip weight information is within the chip range, the processing module outputs a normal grinding signal.

[0067] By adopting the above technical scheme, the first hopper weight information and the process trigger information of the receiving hopper before part processing are first obtained by the acquisition module, and then the processing module controls the grinding wheel operation according to the process trigger information to grind the shaft parts. The material removed by the shaft parts processing is moved to the receiving hopper, so that the weight of the receiving hopper can be re-tested after the shaft parts processing is completed, so as to obtain the weight of the material removed by the shaft parts processing. By judging the weight, it can be determined whether the shaft parts are in a normal processing state, and the wear condition of the grinding wheel can be judged, so that the staff can know whether the grinding wheel can meet the grinding requirements.

[0069] An intelligent terminal comprises a memory and a processor, wherein the memory stores a computer program which can be loaded by the processor and execute any one of the above-mentioned grinding wheel life detection methods.

[0070] By adopting the above technical solution and using the intelligent terminal, the weight information of the first hopper and the process trigger information of the receiving hopper before the parts processing are first obtained, and then the grinding wheel operation is controlled according to the process trigger information to grind the shaft parts. The material removed by the shaft parts processing is moved to the receiving hopper, so that the weight of the receiving hopper can be re-tested after the shaft parts processing is completed, so as to obtain the weight of the material removed by the shaft parts processing. By judging the weight, it can be determined whether the shaft parts are in a normal processing state, and the wear condition of the grinding wheel can be judged, so that the staff can know whether the grinding wheel can meet the grinding requirements.

[0071] In a fourth aspect, the present application provides a computer storage medium capable of storing a corresponding program, having the feature of detecting the wear of a grinding wheel, and adopting the following technical solution:

[0072] A computer-readable storage medium stores a computer program that can be loaded by a processor and execute any one of the above-mentioned grinding wheel life detection methods.

[0073] By adopting the above technical scheme, there is a computer program of the grinding wheel life detection method in the storage medium, which first obtains the first hopper weight information and the process trigger information of the receiving hopper before the part processing, and then controls the grinding wheel operation according to the process trigger information to grind the shaft parts. The material removed by the shaft parts processing is moved to the receiving hopper, so that after the shaft parts processing is completed, the weight of the receiving hopper can be re-detected, so as to obtain the weight of the material removed by the shaft parts processing. By judging the weight, it can be determined whether the shaft parts are in a normal processing state, and the wear condition of the grinding wheel can be judged, so that the staff can know whether the grinding wheel can meet the grinding requirements.

[0074] In summary, the present application includes at least one of the following beneficial technical effects:

[0077] 3. The remaining available area of ​​the grinding wheel can be divided so that the grinding wheel that meets the processing requirements can be moved and continued to be used, reducing the waste of resources. BRIEF DESCRIPTION OF THE DRAWINGS

[0088] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-10 It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0089] The embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings.

[0090] The embodiment of the present application discloses a method for detecting the life of a grinding wheel. The method detects the weight of chips generated by machining shaft parts to detect the state of the grinding wheel, thereby determining the wear condition of the grinding wheel. At the same time, it can eliminate the entry of foreign matter into the docking hopper to improve the accuracy of the detection of the wear condition of the grinding wheel.

[0091] Reference Figure 1 The method flow of grinding wheel life detection includes the following steps:

[0092] Step S100: obtaining the first hopper weight information and process trigger signal of the preset receiving hopper before part processing.

[0093] The receiving hopper is a component on the grinding equipment used to remove material from shaft-type parts. It is located below the grinding wheel so that chips can fall into the receiving hopper when the grinding wheel processes shaft-type parts. The hopper is open at the top, and the remaining side walls and bottom are closed; the weight corresponding to the first hopper weight information is the overall weight of the hopper before part processing, which includes the weight of the hopper itself and the weight of the chips inside the hopper. The weight is obtained by installing a pressure sensor at the bottom of the hopper to measure the overall weight of the hopper. This is a conventional technical means for those skilled in the art and will not be elaborated on; the process trigger signal is a signal to control the grinding equipment for processing, which is manually input by the staff according to the actual processing situation.

[0094] Step S101: Controlling a preset grinding wheel operation for a preset fixed time according to a process trigger signal, and obtaining weight information of a second hopper of the receiving hopper after the operation is completed.

[0095] The grinding wheel is a grinding wheel on the grinding equipment used to process shaft parts. The two grinding wheels are arranged opposite to each other and there is a certain gap between them. During the operation of the grinding wheels, the two grinding wheels rotate in opposite directions and both rotate downward between the two. The fixed time is a fixed value, which is the time set by the staff for normal processing of shaft parts. The specific value is set by the staff according to the actual processing situation of the shaft parts and will not be elaborated on. When the process trigger signal is obtained, the grinding wheel operates for a fixed time to achieve normal processing of shaft parts. The weight value corresponding to the second hopper weight information is the weight of the entire receiving hopper after the parts processing is completed. The acquisition method is the same as the first hopper weight information and will not be elaborated on.

[0096] Step S102: Determine the weight information of the debris by calculating according to the weight information of the second hopper and the weight information of the first hopper.

[0097] The weight value corresponding to the debris weight information is the increase in weight of the receiving hopper before and after the shaft parts are processed, that is, the weight of the material removed from the shaft parts. The calculation method is the weight corresponding to the second hopper weight information minus the weight corresponding to the first hopper weight information.

[0098] Step S103: determining whether the weight value corresponding to the debris weight information is within a preset debris range.

[0099] The debris range is the debris weight range that can be generated during the normal processing of shaft parts set by the staff. The purpose of the judgment is to know whether the debris weight generated by the currently processed shaft parts is normal, so as to facilitate the subsequent detection and judgment of the grinding wheel wear condition.

[0100] Step S1031: If the weight value corresponding to the chip weight information is not within the chip range, a grinding abnormality signal is output.

[0101] When the weight value corresponding to the debris weight information is not within the debris range, it means that the processing process of the current shaft parts is abnormal, that is, there is a grinding abnormality. It may be that the grinding wheel is too severely worn, resulting in poor grinding effect. At this time, a grinding abnormality signal is output to mark the situation so that the staff can be aware of the situation in time. The grinding abnormality signal can be an indicator light preset on the grinding equipment, or it can be a prompt sound. The specific signal output method is set by the staff according to the actual situation and will not be elaborated on.

[0102] Step S1032: If the weight value corresponding to the chip weight information is within the chip range, a normal grinding signal is output.

[0103] When the weight value corresponding to the debris weight information is within the debris range, it indicates that the processing of the shaft parts currently being processed is normal, that is, there is no abnormal grinding. The grinding wheel at this time can meet the normal processing of shaft parts, that is, the wear of the grinding wheel is relatively light. At this time, a normal grinding signal is output to identify the situation so that the staff can be informed of the situation.

[0104] Reference Figure 2 When the weight value corresponding to the chip weight information is not within the chip range, the grinding wheel life detection method further includes:

[0105] Step S200: dividing the time when the process trigger signal is output on the preset time axis into detection intervals with widths of preset fixed values, and controlling the detection intervals to move in positive order on the time axis.

[0106] The time axis is a coordinate axis in the direction of time flow in the physical sense, which is composed of various time points that have passed, combined with Figure 3 When the process trigger signal is output, it means that the grinding wheel starts to work. At this time, a detection interval with a fixed width is defined to detect the machining process of shaft parts. The fixed value is a fixed value, which is set by the staff according to the actual situation. Preferably, the fixed value can be 1 second, so as to detect the situation during the operation of the grinding wheel; the detection interval is controlled to move in positive sequence on the time axis, so that the detection interval can detect all situations in the machining process of shaft parts, so as to facilitate the subsequent further analysis of the wear of the grinding wheel.

[0107] Step S201: define the endpoint closer to the beginning of the detection interval as the initial point and the endpoint closer to the end of the detection interval as the end point.

[0108] The two endpoints of the detection interval are defined as the initial point and the end point, respectively, so as to facilitate the subsequent call and analysis of the data at the two time points in the detection interval.

[0109] Step S202: Acquire the initial weight information of the receiving hopper at the initial point and the final weight information of the receiving hopper at the final point.

[0110] The weight value corresponding to the initial weight information is the overall weight value of the receiving hopper at the initial point, and the weight value corresponding to the final weight information is the overall weight value of the receiving hopper at the final point, both of which are obtained by calling the acquired data.

[0111] Step S203: Calculate and determine the change weight information based on the final weight information and the initial weight information.

[0112] The weight value corresponding to the changed weight information is the overall weight change value of the hopper at both ends before and after the detection interval, and the calculation method is the weight value corresponding to the termination weight information minus the weight value corresponding to the initial weight information.

[0113] Step S204: Determine whether the weight value corresponding to the changed weight information is greater than the preset sudden change weight.

[0114] The sudden change weight is a fixed value set by the staff as the maximum weight value of the chips that normally fall into the receiving hopper. The purpose of the judgment is to find out whether there is a sudden increase in the weight of the receiving hopper, that is, to judge whether there is any foreign matter entering the receiving hopper.

[0115] Step S2041: If the weight value corresponding to the changed weight information is greater than the sudden change weight, a foreign object entry signal is output.

[0116] When the weight value corresponding to the changed weight information is greater than the sudden change weight, it means that the weight of the receiving hopper corresponding to the two endpoints before and after the detection interval has changed greatly, and there is a situation where foreign matter has entered the receiving hopper and caused the weight of the receiving hopper to change suddenly. At this time, a foreign matter entry signal is output to identify the situation so as to facilitate further processing of the situation.

[0117] Step S2042: If the weight value corresponding to the changed weight information is not greater than the sudden change weight, a grinding abnormality signal is output.

[0118] When the weight value corresponding to the changed weight information is not greater than the sudden change weight, it means that the weight change of the receiving hopper corresponding to the two endpoints before and after the detection interval is small, and there is no interference caused by external foreign matter. At this time, the reason for the inconsistent data changes before and after the processing of the receiving hopper is the abnormal grinding of the grinding wheel, and the abnormal grinding signal is output to identify the situation.

[0119] Reference Figure 4 After the foreign matter entry signal is output, the grinding wheel life detection method also includes:

[0120] Step S300: define the end point at this time as a mutation point, and define the position on the time axis that is a preset unit value away from the mutation point as a normal point and a stable point, and the normal point is before the stable point on the time axis.

[0121] When the foreign object enters the hopper and the signal is output, the end point at this time is the time point when the weight of the receiving hopper changes suddenly. The end point is defined as the mutation point for identification, so as to facilitate the analysis of the grinding wheel condition; the unit value is the time unit value set by the staff, which can be 0.2 seconds. The setting of this unit value can eliminate the impact of the foreign object on the weight detection of the receiving hopper after the foreign object falls into the receiving hopper. The point on the time axis that is a unit value away from the mutation point is defined as a normal point and a stable point, so as to facilitate the subsequent call of the data corresponding to the two time points, wherein the stable point is the time node after the impact force of the foreign object disappears.

[0122] Step S301: obtaining normal weight information of the receiving hopper at a normal point and stable weight information of the receiving hopper at a stable point.

[0123] The weight value corresponding to the normal weight information is the overall weight value of the receiving hopper when it is at the normal point, and the weight value corresponding to the stable weight information is the overall weight value of the receiving hopper when it is at the stable point. The acquisition method is the same as above and will not be repeated here.

[0124] Step S302: Determine the weight information of the foreign object by calculating based on the stable weight information and the normal weight information.

[0125] The weight value corresponding to the foreign matter weight information is the approximate weight value of the foreign matter entering the receiving hopper, and the calculation method is the weight corresponding to the stable weight information minus the weight corresponding to the normal weight information.

[0126] Step S303: Calculate and determine actual chip weight information based on the chip weight information and the foreign matter weight information.

[0127] The weight value corresponding to the actual chip weight information is the weight value of the chips that actually fall into the receiving hopper after foreign matter appears during the processing of shaft parts. The calculation method is the weight corresponding to the chip weight information minus the weight corresponding to the foreign matter weight information.

[0128] Step S304: determining whether the weight value corresponding to the actual chip weight information is within the chip range.

[0129] The purpose of the judgment is to find out whether the weight of the chips generated by the machining of shaft parts is normal after eliminating the interference of foreign matter, that is, to judge whether the grinding wheel can normally process the shaft parts after eliminating the interference of foreign matter.

[0130] Step S3041: If the weight value corresponding to the actual chip weight information is within the chip range, a normal grinding signal is output.

[0131] When the weight value corresponding to the actual chip weight information is within the debris range, it means that the weight of the chips generated by the machining of shaft parts is normal after eliminating interference from foreign matter, that is, the grinding wheel processes the shaft parts normally. At this time, the degree of wear of the grinding wheel is relatively light, and a normal grinding signal is output to record the situation.

[0132] Step S3042: If the weight value corresponding to the actual chip weight information is not within the chip range, a grinding abnormality signal is output.

[0133] When the weight value corresponding to the actual chip weight information is not within the debris range, it means that the chip weight generated by the shaft parts processing is still abnormal after eliminating the interference of foreign matter, that is, the grinding wheel is severely worn and the shaft parts cannot be polished well. At this time, an abnormal grinding signal is output to record the situation so that the staff can be informed of the situation in time for subsequent processing.

[0134] Reference Figure 5 , and also includes a method for determining foreign matter weight information, the method comprising:

[0135] Step S400: defining the changed weight information of the first detection interval as standard weight information.

[0136] The first detection interval is the position after the detection interval is formed. The change weight information of the detection interval is defined as standard weight information for identification to record the normal change in material removed from shaft parts during processing before and after the detection interval.

[0137] Step S401: Determine the time proportion ratio according to the fixed value and the unit value.

[0138] The time proportion ratio is the time proportion that the time difference between the normal point and the stable point intersects with a fixed value. The calculation formula is , where I is the time proportion, N is the unit value, and M is a fixed value.

[0139] Step S402: Determine the weight information of the chips entering the bucket between the normal point and the stable point according to the time proportion ratio and the standard weight information.

[0140] The weight value corresponding to the inlet weight information is the approximate weight value of the chips entering the receiving hopper between the normal point and the stable point. The calculation formula is: , where A is the weight value corresponding to the feed bucket weight information, and B is the weight value corresponding to the standard weight information.

[0141] Step S403: Determine the foreign matter weight information by calculating based on the stable weight information, the normal weight information and the feed bucket weight information, wherein the foreign matter weight information is the difference between the stable weight information and the feed bucket weight information.

[0142] The normal weight value of the chips is subtracted from the weight value added by the receiving hopper at the normal point and the stable point to further accurately determine the weight of the foreign matter entering the receiving hopper, thereby realizing the detection and analysis of the weight of the foreign matter.

[0143] Reference Figure 6 After the abnormal grinding signal is output, the grinding wheel life detection method further includes:

[0144] Step S500: obtaining the processing length information of the shaft parts, the abnormal area information and the invalid area information of the grinding wheel.

[0145] The length corresponding to the processing length information is the length of the shaft parts to be processed in the axial direction. It is manually input by the staff according to the shaft parts to be processed. Figure 7 The area range corresponding to the abnormal area information is the area range of the relative position of the grinding wheel and the shaft parts when the grinding abnormal signal is output, and the area range corresponding to the invalid area information is the area range where the grinding wheel is severely worn before the current processing.

[0146] Step S501: determining the standby area information according to the abnormal area information, the invalid area information and the preset working area of ​​the grinding wheel.

[0147] The operating area is the area on the grinding wheel where grinding operations can be performed when there is no severely worn area. The area range corresponding to the standby area information is the range of the remaining usable grinding area on the grinding wheel, that is, all areas on the grinding wheel except the severely worn area.

[0148] Step S502: Determine whether the area length corresponding to the standby area information is greater than the length corresponding to the processing length information.

[0149] The purpose of the judgment is to find out whether the area available for normal grinding of the current grinding wheel can meet the normal grinding processing of the current shaft parts.

[0150] Step S5021: If the area length corresponding to the standby area information is not greater than the length corresponding to the processing length information, an invalid signal is output, and the current grinding wheel is controlled to exchange positions with the preset standby grinding wheel.

[0151] When the area length corresponding to the stand-by area information is not greater than the length corresponding to the processing length information, it means that the current grinding wheel cannot continue to grind the shaft part. At this time, an invalid signal is output to record the situation; at the same time, the current grinding wheel and the spare grinding wheel are controlled to exchange positions to realize automatic replacement of the grinding wheel, so that the grinding wheel does not need to be manually replaced during the processing of shaft parts, thereby improving the working efficiency. The spare grinding wheel is set on the grinding equipment in advance, and the method of exchanging positions can be completed by a robot operation, which is a conventional technical means of those skilled in the art and will not be elaborated on.

[0152] Step S5022: If the area length corresponding to the standby area information is greater than the length corresponding to the processing length information, a valid signal is output.

[0153] When the area length corresponding to the standby area information is greater than the length corresponding to the processing length information, it means that the remaining available area of ​​the grinding wheel at this time can meet the grinding processing of the shaft parts. At this time, a valid signal is output to record the situation, so as to facilitate further control of the grinding wheel later.

[0154] Reference Figure 8 Before and after the current grinding wheel is replaced with the spare grinding wheel, the grinding wheel life detection method further includes:

[0155] Step S600: obtaining usage area information of the spare grinding wheel.

[0156] The area range corresponding to the use area information is the area range in which the spare grinding wheel can perform normal grinding processing on shaft parts.

[0157] Step S601: Determine whether the area length corresponding to the use area information is greater than the length corresponding to the processing length information.

[0158] The purpose of the judgment is to know whether the spare grinding wheel can perform normal grinding processing on the current shaft parts, that is, it is possible that the spare grinding wheel is a severely worn grinding wheel that has been replaced before. Based on the judgment, the replacement of the grinding wheel can be further controlled.

[0159] Step S6011: If the area length corresponding to the use area information is greater than the length corresponding to the processing length information, the current grinding wheel and the spare grinding wheel are controlled to exchange positions, and a valid signal is output.

[0160] When the area length corresponding to the usage area information is greater than the length corresponding to the processing length information, it means that the spare grinding wheel can meet the normal processing of the current shaft parts. At this time, the current grinding wheel and the spare grinding wheel are controlled to exchange positions so that the spare grinding wheel can continue to process the shaft parts, and an effective signal is output to mark the situation so that the staff can be informed of the situation.

[0161] Step S6012: If the area length corresponding to the use area information is not greater than the length corresponding to the processing length information, a standby invalid signal is output.

[0162] When the area length corresponding to the usage area information is not greater than the length corresponding to the processing length information, it means that the spare grinding wheel is also unable to meet the normal grinding processing of the current shaft parts, that is, the spare grinding wheel is also the grinding wheel that has been replaced before. At this time, a spare invalid signal is output to let the staff know the situation so that the staff can manually replace the grinding wheel in time to reduce the situation where the grinding wheel is severely worn and the shaft parts cannot be ground normally.

[0163] Reference Fig. 9 After the effective signal is output, the grinding wheel life detection method also includes:

[0164] Step S700: Obtain boundary line information of an area corresponding to the abnormal area information and an area corresponding to the standby area information.

[0165] The boundary line corresponding to the boundary line information is the boundary line of the area corresponding to the abnormal area information and the area corresponding to the standby area information, such as Figure 7 As shown, if the grinding wheel is a brand new grinding wheel, the boundary line corresponding to the boundary line information is a certain edge boundary line of the grinding wheel set by the staff.

[0166] Step S701: Control the grinding wheel to move along a preset fixed direction and determine whether the boundary line corresponding to the boundary line information coincides with the preset operation line.

[0167] The fixed direction is the direction of movement of the grinding wheel set by the staff. This direction is parallel to the axial direction of the shaft parts so that the grinding wheel can process the shaft parts normally after movement. The specific direction is set by the staff according to actual conditions and will not be elaborated on. The operation line is the corresponding line of the plane of the end portion of the shaft parts away from the area corresponding to the stand-by area information. The purpose of the judgment is to know whether the grinding wheel is moved to a position where the shaft parts can be processed normally during the movement of the grinding wheel.

[0168] Step S7011: If the boundary line corresponding to the boundary line information does not overlap with the working line, the grinding wheel is controlled to continue moving and an adjustment signal is output.

[0169] When the boundary line corresponding to the boundary line information does not coincide with the operation line, it means that the grinding wheel has not moved to a position where shaft parts can be normally ground. At this time, the grinding wheel can be controlled to continue moving, and an adjustment signal can be output to let the staff know that the grinding wheel is in a position adjustment state.

[0170] Step S7012: If the boundary line corresponding to the boundary line information coincides with the working line, the grinding wheel is controlled to stop moving and an adjustment completion signal is output.

[0171] When the boundary line corresponding to the boundary line information coincides with the operation line, it means that the grinding wheel has moved to a position where shaft parts can be normally ground. At this time, the grinding wheel is stopped so that subsequent grinding wheels can process shaft parts normally. At the same time, an adjustment completion signal is output to inform the staff that the grinding wheel position adjustment is completed, so that the staff can manually input a process trigger signal to realize the continued processing of shaft parts.
