An embodiment of the present invention provides a workpiece processing control method, and referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of the workpiece processing control method according to the present invention.
In this embodiment, the workpiece processing control method includes the following steps:
step S10: acquiring original sampling data of a workpiece to be processed, and determining a welding seam window according to workpiece parameters of the workpiece to be processed and the original sampling data.
It should be noted that the execution main body of the present embodiment may be a computing service device with data processing, network communication and program running functions, such as an upper computer, a tablet computer, a personal computer, a mobile phone, or an electronic device, a workpiece processing control device, etc. capable of implementing the above functions, and the present embodiment and each of the following embodiments are described below by taking the workpiece processing control device as an example.
It can be understood that, a rotation of the worktable for processing the workpiece is 360 degrees, the original sampling data are data corresponding to the worktable angle value and the concave-convex value of the surface of the workpiece to be processed one by one, which are collected by the encoder for feeding back the worktable angle value and the concave-convex value for feeding back the concave-convex value of the surface of the workpiece to be processed, the collected data are sorted according to the worktable angle value, wherein each pair of data in the original sampling data comprises the worktable angle value and the concave-convex value of the surface of the workpiece to be processed, and the worktable angle value and the workpiece to be processed show the concave-convex value one by one.
It should be understood that there is a weld on the workpiece to be processed, and therefore, the original sampled data includes the weld sampled data at the weld, the workpiece parameters include the workpiece diameter, the arc length, the height, and other parameters of the workpiece to be processed, the weld window is a window for finding the weld sampled data in the original sampled data, and the size of the weld window is equal to half of the weld sampled data of one weld of the workpiece to be processed.
Step S20: and determining the welding seam data position of the welding seam sampling data in the original sampling data according to the welding seam window and the original sampling data.
It can be understood that the welding seam data position is the position of the corresponding workbench angle value of the welding seam sampling data in the original sampling data, and the welding seam data position of the welding seam sampling data is sequentially searched according to the angle value of the workbench in the original sampling data according to the welding seam window.
Step S30: and processing the original sampling data according to the position of the welding seam data to obtain smooth sampling data of the workpiece to be processed.
It should be understood that during the process of processing the workpiece to be processed, the weld seam sampling data can cause workpiece out-of-tolerance, therefore, after the position of the weld seam data is determined, the weld seam data at the position is processed to eliminate data mutation at the weld seam, and after the original sampling data is processed, smooth sampling data is obtained.
Step S40: and sending the smooth sampling data to a processing system so that the processing system processes the workpiece to be processed according to the smooth sampling data.
It should be understood that the smooth sampled data is obtained after the original sampled data is processed, and the smooth sampled data is sent to the processing system, so that when the processing system receives the smooth sampled data, the workpiece to be processed can be processed according to the smooth sampled data.
Further, in order to improve the accuracy of processing the workpiece to be processed, the step S20 includes: dividing the original sampling data into a plurality of data sets according to the welding seam window, and acquiring an extreme value corresponding to each data set; and determining a difference sequence according to the extreme values corresponding to the data sets, and determining the weld data position of the weld sampled data in the original sampled data according to the difference sequence.
It can be understood that, a workpiece to be processed is placed on the workbench for processing, and a set of complete original sampling data can be obtained by rotating the workbench for one turn, that is, 360 degrees.
It can be understood that, assuming that the workbench rotates one circle to obtain a group of original sampling data, the original sampling data is divided into a plurality of data sets according to the angle value of the workbench from small to large, the extreme value corresponding to each data set has two, one maximum value and one minimum value, because the original sampling data is ordered according to the angle value of the workbench, the extreme value difference corresponding to each data set is obtained by subtracting the extreme value corresponding to the smaller angle value of the workbench from the extreme value corresponding to the larger angle value of the workbench, the absolute value of the extreme value difference is ordered from large to small to obtain a difference sequence, the position of the welding seam data can be determined according to the first n values in the difference sequence, wherein n is the number of welding seams, because the welding seams are convex on the surface of the workpiece to be processed, the absolute value of the extreme value difference of the data set corresponding to the welding seam sampling data is larger than the absolute value of the extreme value difference corresponding to other data sets, each extreme value difference value corresponds to a data set, and each data set comprises a data pair of the angle value of the workbench and the concave-convex value of the surface of the workpiece to be processed, so that the position of the welding seam data of the welding seam sampling data in the original sampling data can be determined after n large extreme value difference values are obtained.
Further, in order to accurately determine the arc length of the weld of the workpiece to be processed, before the step S10, the method further includes: and acquiring the arc length of the welding seam corresponding to each welding seam on the workpiece to be processed, and selecting the maximum arc length of the welding seam from the arc lengths of the welding seams as the actual arc length of the welding seam of the workpiece to be processed.
It should be understood that the workpiece to be processed is formed by welding a plurality of small workpieces after being spliced, so that the workpiece to be processed has welding seams, the arc length of the welding seam corresponding to each welding seam can be obtained through measurement of an instrument, and the largest arc length of the welding seams in the arc lengths of the welding seams is used as the actual arc length of the welding seam of the workpiece to be processed.
Further, in order to improve the accuracy of processing the workpiece to be processed, the step S30 includes: determining target data according to the position of the welding seam data, and determining an interval value between adjacent sampling positions in the welding seam sampling data according to the target data; and processing the welding seam sampling data according to the interval value to obtain smooth sampling data of the workpiece to be processed.
It can be understood that the target data is weld sampled data in the original sampled data, and after the target data is determined, the abrupt data in the original sampled data can be processed to obtain smooth sampled data.
Further, in order to improve the accuracy of processing the workpiece to be processed, the step S40 includes: and sending the smooth sampling data to a processing system so that the processing system processes the workpiece to be processed according to the smooth sampling data when the smooth sampling data meets a preset condition.
It should be understood that, after the smooth sampled data is sent to the machining system, the machining system further has a judging step, and after the smooth sampled data meets the preset condition, the workpiece to be processed is machined according to the smooth sampled data, wherein the judging step can be automatically completed by equipment, or can be manually checked, and is mainly used for determining whether the position of the weld data is accurately determined.
In particular implementations, for example: the workpiece to be processed is a right cylindrical workpiece which is spliced by welding 6 three-dimensional circular arcs, the height of the workpiece is about 20 cm, 6 welding seams are arranged on the workpiece, the arc length of each welding seam can be measured by an instrument, original sampling data collected by an encoder feeding back the angle value of the worktable and the concave-convex value of the surface of the workpiece to be processed are obtained, 8000 pairs of data are arranged in the original sampling data, a determined welding seam window is assumed to be 26, each 26 pairs of sampling data are divided into a data set, the data from the 1 st pair to the 26 th pair are selected from the 8000 pairs of original sampling data to be used as a first data set, the maximum value and the minimum value of the concave-convex value of the surface of the workpiece to be processed in the 26 pairs of data are obtained, the extreme value corresponding to the larger angle value of the worktable is subtracted from the extreme value corresponding to the smaller angle value to obtain the 1 st extreme value difference value, and then the data from the 2 nd pair to the 27 th pair are selected, obtaining the maximum value and the minimum value of the concave-convex value of the surface of the workpiece to be processed in the 26 data again, subtracting the extreme value corresponding to the smaller workbench angle value from the extreme value corresponding to the larger workbench angle value to obtain the 2 nd extreme value difference value, obtaining 7963 extreme value difference values to form a difference value sequence, sorting the absolute values of the extreme value difference values in the difference value sequence from large to small, wherein the workbench angle value corresponding to the absolute value of the first 6 extreme value difference values after sorting is the welding seam data position of the welding seam sampling data, replacing 6 groups of welding seam sampling data corresponding to 6 welding seams after determining the specific position of the welding seam sampling data in the original sampling data, wherein each group of welding seam sampling data has 53 pairs of data, assuming that the 1 st welding seam spans from 816 th to 868th pairs of data, subtracting the concave-convex value of the workpiece to be processed in the data by 815 th pair of data from the concave-convex value of the workpiece to be processed in the data by 869 to obtain an interval value p, the method comprises the steps of replacing the concave-convex value of a workpiece to be processed in 816 th pair of data with the concave-convex value of the workpiece to be processed in 815 th pair of data plus an interval value p, then sequentially pushing down until the concave-convex value of the workpiece in 868 th pair of data is replaced, according to the processing mode, finishing all replacement of welding seam sampling data corresponding to 6 welding seams to obtain smooth sampling data, sending the smooth sampling data to a processing system, calculating the difference of the concave-convex values corresponding to the angle values of the worktable of the smooth sampling data and the original sampling data, taking an extreme value of a difference result, displaying the two data in a curve, judging whether the smooth sampling data meets preset conditions through instrument equipment or manpower, and processing the workpiece to be processed according to the smooth sampling data when the preset conditions are met.
In the embodiment, a welding seam window is determined by acquiring original sampling data of a workpiece to be processed and according to workpiece parameters of the workpiece to be processed and the original sampling data; determining the welding seam data position of the welding seam sampling data in the original sampling data according to the welding seam window and the original sampling data; processing the original sampling data according to the position of the welding seam data to obtain smooth sampling data of the workpiece to be processed; the smooth sampled data are sent to a processing system, so that the processing system processes the workpiece to be processed according to the smooth sampled data, and because the welding seam window is determined according to the workpiece parameters of the workpiece to be processed and the original sampled data, the data position of the welding seam sampled data in the original sampled data is determined according to the welding seam window, and the smooth sampled data are obtained by processing the original sampled data according to the data position, the processing system processes the workpiece to be processed according to the smooth sampled data, the technical problem that the workpiece is out of tolerance when the workpiece is processed in the prior art is solved, and the accuracy of workpiece processing is improved.
