Referring to fig. 1, the method flow for detecting the service life of the grinding wheel comprises the following steps:
step S100: the method comprises the steps of obtaining weight information of a first hopper of a preset receiving hopper before part processing and a process triggering signal.
The receiving hopper is a component used for removing materials on the connecting shaft parts on the grinding equipment and is positioned below the grinding wheel, so that scrap blocks can fall into the receiving hopper when the grinding wheel processes the shaft parts, an opening is formed above the receiving hopper, and the rest side walls and the bottom surface are closed; the weight corresponding to the first hopper weight information is the whole weight of the receiving hopper before part processing, the weight comprises the weight of the receiving hopper and the weight of the scrap block in the receiving hopper, and the whole weight of the receiving hopper is obtained by installing a pressure sensor at the bottom of the receiving hopper, so that the method is a conventional technical means for a person skilled in the art and is not described again; the process trigger signal is a signal for controlling the grinding equipment to process and is manually input by a worker according to the actual processing condition.
Step S101: and controlling the preset grinding wheel operation to preset fixed time according to the process trigger signal, and acquiring the second hopper weight information of the receiving hopper after the operation is finished.
The grinding wheels are used for processing shaft parts on grinding equipment, the two grinding wheels are arranged oppositely, a certain gap is formed between the two grinding wheels, in the grinding wheel operation process, the rotating directions of the two grinding wheels are opposite, the two grinding wheels rotate towards the lower part between the two grinding wheels, the fixed time length is a fixed value, the time length which is set by a worker and can be used for normally processing the shaft parts is set, the specific numerical value is set by the worker according to the actual processing condition of the shaft parts, and the detailed description is omitted; when a process trigger signal is acquired, the operation of the grinding wheel is fixed for a fixed time, so that the normal processing of the shaft parts is realized; the weight value corresponding to the second hopper weight information is the whole weight of the receiving hopper after the parts are machined, and the obtaining method is consistent with the first hopper weight information and is not described repeatedly.
Step S102: a calculation is made from the second hopper weight information and the first hopper weight information to determine the chip weight information.
The weight value corresponding to the scrap weight information is the weight increment of the receiving hopper before and after the shaft parts are machined, namely the weight of the materials removed from the shaft parts, and the calculation method is that the weight corresponding to the first hopper weight information is subtracted from the weight corresponding to the second hopper weight information.
Step S103: and judging whether the weight value corresponding to the scrap weight information is in a preset scrap range or not.
The chip range is the chip weight range which can be generated when the shaft part set by the operator is normally processed, and the purpose of judgment is to know whether the chip weight generated by the currently processed shaft part is normal or not so as to conveniently detect and judge the abrasion condition of the grinding wheel subsequently.
Step S1031: and if the weight value corresponding to the scrap weight information is not in the scrap range, outputting a grinding abnormal signal.
When the weight value that corresponds when piece weight information is not in the piece within range, it is unusual to explain the axle type part machining process that is currently processed, there is the unusual condition of polishing promptly, it is too serious and lead to polishing effect not good to polish the wheel wearing and tearing, output this moment and polish unusual signal in order to sign this condition, so that the staff in time learns this condition, should polish unusual signal and can be bright for the pilot lamp of presetting on the grinding equipment, also can be for the suggestion sound, concrete signal output mode is set for by the staff according to actual conditions, do not describe repeatedly.
Step S1032: and if the weight value corresponding to the scrap weight information is in the scrap range, outputting a normal polishing signal.
When the weight value that piece weight information corresponds was in the piece within range, it was normal to explain the axle type part course of working currently, did not have the unusual condition of polishing promptly, and the wheel of polishing this moment can satisfy the normal processing of axle type part, and the wheel of polishing promptly wearing and tearing condition is lighter, and the normal signal of polishing is in order to sign this condition this moment to make the staff learn this condition.
Referring to fig. 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:
step S200: and dividing the time of the process trigger signal output on a preset time axis backwards to form a detection interval with the width of a preset fixed value, and controlling the detection interval to move on the time axis in a positive sequence.
The time axis is a coordinate axis in the time lapse direction in a physical sense and consists of elapsed time points, and with reference to fig. 3, when a process trigger signal is output, the grinding wheel starts to operate, and a detection interval with a fixed width is defined at the moment so as to detect the machining process of shaft parts, wherein the fixed value is a fixed value and is set by an operator according to an actual situation, preferably, the fixed value can be 1 second so as to detect the situation in the working process of the grinding wheel; and controlling the detection interval to move on the time axis in a positive sequence so that the detection interval can detect all conditions of the shaft parts in the machining process, and further analyzing the abrasion condition of the grinding wheel in the follow-up process.
Step S201: defining the endpoint at the front of the detection interval as the initial point and the endpoint at the back as the final point.
And respectively defining the two end points of the detection interval as an initial point and an end point so as to be convenient for calling and analyzing each data of the two time points of the detection interval subsequently.
Step S202: acquiring initial weight information of the material receiving hopper at an initial point and termination weight information of the material receiving hopper at a termination point.
The weight value that initial weight information corresponds is the bulk weight value of connecing the hopper when initial point, and the bulk weight value that the corresponding weight value of termination weight information is the bulk weight value of connecing the hopper when termination point, and both all call in order to obtain through the data to acquireing.
Step S203: and calculating according to the termination weight information and the initial weight information to determine the change weight information.
The weight values corresponding to the change weight information are the whole weight change values of the material receiving hoppers at the front end point and the rear end point of the detection interval, and the calculation method is that the weight value corresponding to the termination weight information subtracts the weight value corresponding to the initial weight information.
Step S204: and judging whether the weight value corresponding to the change weight information is larger than the preset mutation weight or not.
The sudden change weight is the maximum weight value that the bits piece normally falls into the receiving hopper for the fixed value that the staff set for, and the purpose of judgement is in order to learn whether to connect the hopper to have the condition that the weight sudden change increases, judges whether to have the condition that external foreign matter got into the receiving hopper promptly.
Step S2041: and if the weight value corresponding to the change weight information is larger than the mutation weight, outputting a foreign matter entering signal.
When the weight value corresponding to the change weight information is larger than the mutation weight, the change of the weight of the material receiving hopper corresponding to the front end point and the rear end point of the detection interval is larger, the condition that the weight of the material receiving hopper mutates due to the fact that external foreign matters enter the material receiving hopper exists, and at the moment, foreign matter entering signals are output to mark the condition so as to further process the condition subsequently.
Step S2042: and if the weight value corresponding to the change weight information is not greater than the mutation weight, outputting a polishing abnormal signal.
When the weight value that change weight information corresponds is not more than sudden change weight, it explains that the weight change that two endpoints correspond before and after the detection interval connect the hopper is less, does not have the interference that external foreign matter caused, connects the inconsistent reason of data change promptly to polish the wheel and polish unusually before and after the hopper processing this moment, and the output is polished unusual signal and is in order to sign this condition.
Referring to fig. 4, after the foreign matter entering signal is output, the method for detecting the service life of the grinding wheel further includes:
step S300: defining the ending point as a catastrophe point, defining the position which is away from the catastrophe point by a preset unit value on a time axis as a normal point and a stable point, and the normal point is before the stable point on the time axis.
When the foreign matter enters the signal output, defining the termination point as a sudden change point for marking so as to analyze the condition of the grinding wheel, wherein the termination point is the time point when the weight of the receiving hopper suddenly changes; the unit value is a time unit value set by a worker and can be 0.2 second, the unit value can enable foreign matters to fall to the receiving hopper and then eliminate the influence of foreign matter impact force on weight detection of the receiving hopper, and points which are away from the mutation points by the unit value on the time axis are defined as normal points and stable points so as to be convenient for calling data corresponding to the time of the two points subsequently, wherein the stable points are time nodes after the foreign matter impact force disappears.
Step S301: and acquiring the normal weight information of the material receiving hopper at a normal point and the stable weight information of the material receiving hopper at a stable point.
The weight value corresponding to the normal weight information is the whole weight value of the receiving hopper at the normal point, the weight value corresponding to the stable weight information is the whole weight value of the receiving hopper at the stable point, and the obtaining method is the same as the above and is not repeated.
Step S302: and calculating according to the stable weight information and the normal weight information to determine the foreign matter weight information.
The weight value corresponding to the foreign matter weight information is approximately the weight value of the foreign matter entering the receiving hopper, and the calculation method is that the weight corresponding to the stable weight information subtracts the weight corresponding to the normal weight information.
Step S303: actual crumb weight information is determined from the crumb weight information and the foreign matter weight information.
The weight value corresponding to the actual scrap weight information is the weight value of the scrap falling into the receiving hopper after the foreign matter condition occurs in the shaft part machining process, and the calculation method is to subtract the weight corresponding to the foreign matter weight information from the weight corresponding to the scrap weight information.
Step S304: and judging whether the weight value corresponding to the actual chip weight information is in the chip range or not.
The purpose of judgement is whether normal in order to learn the produced bits piece weight of axle type parts machining after getting rid of the foreign matter interference, judges promptly that to get rid of the normal processing of axle type parts of the grinding wheel after the foreign matter interference.
Step S3041: and if the weight value corresponding to the actual chip weight information is in the chip range, outputting a normal polishing signal.
When the weight value that actual bits piece weight information corresponds was in the piece within range, the explanation got rid of the produced bits piece weight of foreign matter interference back axle type parts machining and is normal, and the grinding wheel is to axle type parts normal processing promptly, and the grinding wheel wearing degree this moment is lighter, and the normal signal of output polishing is in order to take notes this condition.
Step S3042: and if the weight value corresponding to the actual chip weight information is not in the chip range, outputting a grinding abnormal signal.
When the weight value that actual bits piece weight information corresponds is not in the piece within range, the explanation gets rid of the produced bits piece weight of foreign matter interference back axle type parts machining and is still unusual, has promptly to polish the condition that the wheel wearing and tearing are serious and can't be better to axle type part polish, and the abnormal signal of output is polished in order to take notes this condition this moment to make the staff in time learn this condition, so that subsequent processing.
Referring to fig. 5, a method for determining foreign matter weight information is also included, the method including:
step S400: the variation weight information of the first detection section is defined as standard weight information.
The first detection interval is the position of the detection interval after the detection interval is formed, and the change weight information of the detection interval is defined as standard weight information for identification so as to record the normal change of the material removal of the shaft part in the processing processes before and after the detection interval.
Step S401: the time-to-time ratio is determined from the fixed value and the unit value.
The time ratio is the time ratio of the time difference between the normal point and the stable point intersecting at a fixed value, and the calculation formula is
Wherein I is the time ratio, N is a unit value, and M is a fixed value.
Step S402: and determining the bucket weight information of the chip blocks between the normal point and the stable point according to the time-to-weight ratio and the standard weight information.
The weight value corresponding to the weight information of the feeding hopper is the approximate weight value of the scrap block entering the receiving hopper between the normal point and the stable point, and the calculation formula is
Wherein, A is the weight value corresponding to the weight information of the hopper, and B is the weight value corresponding to the standard weight information.
Step S403: and calculating according to the stable weight information, the normal weight information and the inlet hopper weight information to determine the foreign matter weight information, wherein the foreign matter weight information is the difference obtained by subtracting the normal weight information and the inlet hopper weight information from the stable weight information in sequence.
The normal weight value of the scrap block is removed from the weight value added by the receiving hopper in the normal point and the stable point, so that the weight of the foreign matters entering the receiving hopper is further accurate, and the detection and analysis of the weight of the foreign matters are realized.
Referring to fig. 6, after the abnormal polishing signal is output, the method for detecting the lifetime of the polishing wheel further includes:
step S500: and acquiring the processing length information of the shaft parts, the abnormal area information of the grinding wheel and the invalid area information.
The length corresponding to the processing length information is the length of the shaft part to be processed in the axial direction, and is manually input by a worker according to the processed shaft part, referring to fig. 7, the area range corresponding to the abnormal area information is the area range of the relative position of the polishing wheel and the shaft part when the polishing abnormal signal is output, and the area range corresponding to the invalid area information is the area range of the polishing wheel which is seriously worn before the current processing.
Step S501: and determining standby area information according to the abnormal area information, the invalid area information and the preset working area of the grinding wheel.
The operation area is an area which can be used for polishing when no serious abrasion area appears on the polishing wheel, and the area range corresponding to the standby area information is the range of the residual usable polishing area on the polishing wheel, namely all areas except the serious abrasion area on the polishing wheel.
Step S502: and judging whether the length of the area corresponding to the standby area information is larger than the length corresponding to the processing length information.
