Meanwhile, in the description of the present application, the terms "first", "second", and the like are used only for distinguishing the description, and are not to be construed as indicating or implying relative importance.
As described in the related art, since hole site information is different for different boards, when the numerical control technology is used to control the bit pitch of the multi-row drill, the attitude and position of the multi-row drill need to be adjusted to minimize the number of machining processes of the multi-row drill. However, at present, the posture and the position of the drill bag are manually adjusted by skilled workers according to experience knowledge, so that the requirement on the workers is high, the scheme determined by the workers according to the experience knowledge is not necessarily the optimal scheme, and the manual scheme determination is low in efficiency and is not suitable for large-batch processing. Therefore, the problems of poor stability and low efficiency exist in the current working scheme of the multi-row drill.
Aiming at the problems in the prior art, the application provides a process determination method of numerical control multi-row drill, which comprises the steps of matching hole site data to be processed on a plate model to be processed with a plurality of drill bag models (or drill bags in rows) by obtaining the plurality of drill bag models (or drill bags in rows or plates in rows) and the plate model to be processed (or plates in rows), based on a preset greedy algorithm, obtaining the hole site data to be processed matched with each drill bag model, and the pose data of the drill bag models when the hole site data to be processed are matched, so that the drill bits of the row drill correspond to the hole sites one by one, and determining the postures of the row drill corresponding to different hole sites; determining a model collision relation between each drill ladle model and other drill ladle models in each process based on the pose data of the drill ladle models, so as to determine the possibility of collision between drill ladles in the same process; if the target drill-bag model collides with other drill-bag models, the hole position data to be processed corresponding to the target drill-bag model is moved to the next procedure until the target drill-bag model does not collide with other drill-bag models in the same procedure, procedure information of the numerical control multi-row drill is obtained, and the procedure of the drill-bag model is adjusted according to the collision relation, so that the multi-row drill equipment can process plates with more sizes and types, the condition that the plates exceed the processing area of the multi-row drill equipment and cannot be processed is avoided, the procedure is automatically determined by a computer, and the processing efficiency and the stability of the plates are improved.
Referring to fig. 1, fig. 1 is a flowchart illustrating an implementation of a procedure determination method for a numerical control multi-gang drill according to an embodiment of the present application. The procedure determining method for the numerical control multi-gang drill in the embodiment of the application can be applied to a virtual simulation environment of terminal equipment, wherein the terminal equipment includes but is not limited to computer equipment such as a tablet computer, a desktop computer, a super computer, a physical server and a cloud server. The process determining method of the numerical control multi-gang drill in the embodiment of the application comprises the following steps of S101 to S104:
and S101, acquiring a plurality of drill package models and plate models to be processed.
In this embodiment, the drill-package model and the to-be-processed plate model are virtual simulation models, which may be pre-established or established in real time. Alternatively, the model parameters may be adjusted based on a preset general model. For example, parameters such as the size, the position and the movement constraint of the drill pack of the multi-row drill equipment are obtained, and the model parameters of the universal drill pack model are adjusted by using the parameters to create the drill pack model, so that the sizes of the inner frame and the outer frame of the drill pack are obtained. As shown in fig. 2, a drill-pack model is represented by a rectangle, wherein 21 is a drill bit (a cutter on a drill pack), 22 is an outer drill-pack frame, 23 is a center point of the drill pack, and 24 is an inner drill-pack frame.
In one embodiment, gang drill structure data and plate data to be processed are obtained; and creating a plurality of drill pack models based on the gang drill structure data, and creating a plate model to be processed based on the plate data to be processed.
In this embodiment, the gang drill structure data and the plate data to be processed may be exchanged by using a common json data format. Optionally, configuring information such as the size, the hole position, the limiting position and the like of the drill bit packet, and configuring information such as the plate to be processed and the hole position and the like based on the actual structure of the multi-row drill equipment and the actual structure of the plate to be processed to generate row drill structure data and plate to be processed of a json data structure; the method comprises the steps of establishing a drill packet model according to the gang drill structure data, establishing a plate model to be processed according to the plate data to be processed, and accordingly determining a process scheme aiming at different multi-gang drill equipment and plates with different specifications, and enabling the method to have wider applicability.
And S102, matching the hole site data to be processed on the plate model to be processed with a plurality of drill and bag models based on a preset greedy algorithm to obtain the hole site data to be processed matched with each drill and bag model and the position and orientation data of the drill and bag models when the hole site data to be processed are matched.
In this embodiment, the hole location data to be processed includes coordinate data of each hole location to be processed on the plate, and the pose data includes position data and pose data corresponding to the model pose. In the embodiment, each model posture of the drill-in package model is matched with the holes to be processed in a greedy matching mode, and the drill-in package model posture which is matched to the maximum number of the holes to be processed in one process is used as the model posture in the process. It can be understood that the plate to be processed has a plurality of faces, when each face needs to be processed and the processing range of the drill package model can not cover the whole plate face, in order to reduce the processing procedures of the gang drill or enlarge the size of the processed plate of the gang drill equipment, the plate can be turned and/or rotated, and the posture of the drill package model corresponding to the hole position to be processed is determined when different plate postures are adopted. It should be noted that, in general, a set of holes to be processed corresponds to a drill package model.
Alternatively, since some drill packs require manual movement, in order to reduce manual handling, the matching results ensure that the drill packs are in the initial position as much as possible.
In one embodiment, determining a model attitude of each drill pack model, wherein the model attitude corresponds to pose data of the drill pack model; and determining the hole site data to be processed matched with the model attitude of each drill package model based on a preset greedy algorithm.
In this embodiment, the drill-down package model includes a drill-up package and a drill-down package, and the model pose includes a pose of the drill-up package and a pose of the drill-down package. As shown in fig. 3, the model pose may be the vertical-vertical pose of fig. 3A, the vertical-horizontal pose of fig. 3B, the horizontal-vertical pose of fig. 3C, or the horizontal-horizontal pose of fig. 3D, for example, the vertical is the pose of the drill-up package and the horizontal is the pose of the drill-down package; taking horizontal-vertical as an example, the horizontal is the posture of the drill pipe bag, and the vertical is the posture of the drill pipe bag.
Alternatively, based on the actual equipment configuration, from among the above 4 kinds of model poses, a model pose conforming to the equipment configuration is selected as the process pose. Optionally, the four model attitudes are respectively matched with the hole sites on the plate, the model attitude with the largest number of matched hole sites is selected as the process attitude, and if the number of matched hole sites is the same, the priority order is selected to be vertical-vertical, vertical-horizontal, horizontal-vertical, horizontal-horizontal. In the embodiment, the model posture is used as a matching center, and the hole position data to be processed corresponding to the model posture of each drill packet model is determined, so that the manual operation of adjusting the posture of the drill packet model is reduced, and the automation degree of the processing process is improved.
Illustratively, for the drill packs, x is used to describe the position of each column of drill packs in the x direction, y is used to describe the respective y coordinates of the drill-up pack and the drill-down pack in each column of drill packs, and the boul variable is used to indicate whether each drill pack rotates or not. According to the structure of the drill package, the hole sites in the horizontal direction and the vertical direction belong to the same classification, and the grouping of the horizontal hole sites and the vertical hole sites is obtained (namely the x values of the hole sites are equal or the y values of the hole sites are equal).
Optionally, the greedy algorithm-based matching method includes:
definition of classes: the horizontal category is all hole sites with the same y value, and the vertical category is all hole sites with the same x value. Definition of the group: the transverse groups are hole site groups with the same y value and the difference between the maximum value x and the minimum value x smaller than the length of the single-row drill package. The vertical group is a hole position combination with the same x value and the difference between the maximum value y and the minimum value y smaller than the length of the single-row drill package. The distance between the hole sites in the x or y direction is an integral multiple of 32, and the hole sites are combined together to form a group, namely, a row of vertical drill packets can be used for finishing processing. Alternatively, for the group pitch, the difference between the minimum y of the upper group (two groups for a column of drill packs, i.e., drill-up pack and drill-down pack) and the maximum y of the lower group. The matching success is that the coordinates of the drill bit hole on the drill bag coincide with the coordinates of the hole position on the plate.
Alternatively, for drill packages with vertical-vertical as model pose, it can be matched to one or two sets. Illustratively, the drill packs that move directly to the vertical-to-vertical position are aligned with the hole locations, the lowermost hole is aligned with the lowermost hole of the group, the upper half is machined using the upper drill pack, and the lower half is machined using the lower drill pack. The lower drill package uses the group with the smaller y value, the upper drill package uses the group with the larger y value, and if the upper drill package is aligned with the hole to be processed and exceeds the limit, the upper drill package needs to be moved downwards until the upper drill package is in the limit. If it is not moved into the limit, the hole is marked as unprocessed and put into the next matching process.
Optionally, for the drill package with the horizontal-vertical posture as the model posture, the upper horizontal drill package is matched from the previously classified horizontal grouping, and after the upper horizontal drill package is fixed, the lower vertical row of holes is matched (at this time, the vertical row of drill packages can only move up and down). And similarly, transversely drilling the leftmost hole, aligning the hole with the smallest transverse class x value, then moving one hole by one hole, moving the upper transverse group, and moving the lower vertical drill bag hole up and down to match the hole to be processed. And recording the position with the maximum number of the processing holes, namely the matching result.
Alternatively, for drill packages with vertical-horizontal as model pose, traverse is started in the vertical class, the hole with the largest y value is aligned with the vertical drill package up to the hole, and then the horizontal drill package below is moved up and down to match as many holes as possible in the horizontal class. And recording the position with the most matched holes, namely the matching result.
Optionally, for drill packs with horizontal-horizontal as model pose, the upper one finds the match from the horizontal class, and the lower horizontal drill pack moves the match up and down from the horizontal class whose y value is smaller than the upper horizontal class. And transversely drilling a packet stepping mode, transversely drilling the leftmost hole, aligning to the hole with the minimum transverse x value, then moving one hole by one hole, moving the upper transverse group, and moving the lower transverse hole up and down to match. And recording the position with the most matched holes, namely the matching result. And finally, integrating results of all the postures and selecting the scheme with the largest number of matched holes.
In one embodiment, the plate model to be processed is adjusted to be a first plate posture; when the plate models to be processed are in the first plate posture, determining corresponding first hole site data when the model posture of each drill package model is matched with the maximum hole site to be processed; rotating and/or overturning the plate model to be processed into a second plate posture; and when the plate models to be processed are in the second plate posture, determining corresponding second hole site data when the model posture of each drill package model is matched with the maximum hole site to be processed.
In this embodiment, there are two cases for the first hole site data and the second hole site data when they are processed. The first method comprises the following steps: the first hole site data and the second hole site data are processed independently, namely, before the processing is started, branch calculation is divided into two cases, and finally, the hole site data with fewer working procedures are selected. And the second method comprises the following steps: the first hole site data and the second hole site data are processed together, so that the problem that the hole sites cannot be processed is solved, and all the hole sites can be processed.
For example, if the sheet material meets the preset condition, the sheet material is rotated and/or turned to the second sheet material posture. The preset conditions are that the area to be processed of the plate model to be processed is larger than the processable area of the drill-package model, or the number of the hole sites to be processed on the front side of the plate is larger than the number of the hole sites to be processed on the back side of the plate. The front and the back of the plate or the hole sites on the left side and the right side in different directions are matched by rotating or overturning the plate model to be processed, so that the completeness of hole site matching is ensured, and the matching accuracy is improved. It can be understood that the holes to be processed on the plate are processed according to the procedures, the front holes and the back holes are processed in the same procedure, and the back holes are not processed after the front holes are processed, so that two threads must be established to process the back procedure and the front procedure at the same time.
It can be understood that there are two occasions when the posture of the plate member is adjusted in the present embodiment, the first occasion is adjustment before processing starts, and the purpose is to enumerate all matching possibilities. The second point is the adjustment (processing the hole sites on the left and right sides first, then rotating the hole sites on the upper and lower sides, or rotating the lower half part of the over-area upward) in the processing and processing process, in order to make the plate meet the preset conditions.
And S103, determining model collision relations between each drilling and packaging model and other drilling and packaging models in each process based on the pose data of the drilling and packaging models.
In this embodiment, the interference processing of the calculated pose of the drill package is to calculate the collision between two drill packages (i.e. whether the positions intersect or not), and if there is a collision, the drill package needs to be placed in the next process for processing. Optionally, the collision calculation rule is that the outermost x-direction collision is calculated first. If no collision occurs, executing the following collision calculation process, wherein each row of drill packets is provided with two small drill packets, circularly calculating whether each small drill packet collides with each small drill packet in the next row, and if the collision occurs, indicating that the large drill packet also collides. After each procedure is calculated, the position of the plate needs to be calculated, and the drill package does not move at the initial position as much as possible. The initial origin position of the plate is aligned with the first hole of the horizontal drill. And calculating the maximum value of all the drill packs in the rows moving to the zero position, wherein if the maximum value is smaller than the minimum value of the positioning rod, the plate moving is the minimum value position of the positioning rod, and if the maximum value is larger than the minimum value of the positioning rod, the plate moving is the position moving to the zero position. If there are horizontal holes on the left and right at this time, the shift value must be a multiple of the pitch 32 of the horizontal holes in order to ensure that the horizontal holes can be processed. And circularly processing the result of each procedure until the processing is finished. And obtaining the positions of all drill packages and the positions of the plates.
Illustratively, the drill package structure shown in fig. 2 is schematic. The outer frame is used for calculating transverse collision of the drilling packets, the inner frame is used for calculating whether the upper drilling packets and the lower drilling packets in the same row collide, and the inner frame can rotate by 90 degrees. Alternatively, the collision calculation rule may be: whether the outer frames between the drilling and packing models collide is calculated firstly, and if the outer frames between the drilling and packing models do not collide, whether the inner frames between the drilling and packing models collide is calculated.
And step S104, if the target drill-bag model collides with other drill-bag models, moving the hole site data to be processed corresponding to the target drill-bag model to the next procedure until the target drill-bag model does not collide with other drill-bag models in the same procedure, and obtaining procedure information of the numerical control multi-row drill.
In this embodiment, the generated drill packets are traversed, the collision between the drill packets is calculated by using the boost library, and the drill packets with collision interference are placed in the next process. And (5) circulating the processes until all drill packages are processed. The result after the treatment is that there is no collision interference between the drill packs in each machining pass.
And according to the generated result, decomposing the plate attitude matrix in each process into two processes of turning and rotating. And obtaining the posture of the plate in each procedure, and writing the position of the plate in each procedure and the position of each row of drill packages into the json result.
In an embodiment, before the step S102, the method further includes: if the ratio of the area to be processed of the plate model to be processed to the processable area of the drill package model is larger than a preset value, the plate model to be processed is divided into a first plate model and a second plate model, and the first plate model and the second plate model are used for being respectively matched with the drill package model by means of a greedy algorithm.
In this embodiment, the size of the plate is readjusted according to the parameters of the machining area, and if the plate specification is greater than the machining parameters, the plate can be rotated 180 degrees, and the area where the lower half cannot be machined is rotated to the upper half to be machined by using a horizontal drill. In this case, the total length of the plate is required to be 2 times of the processing area, otherwise, the plate cannot be processed even if the plate is rotated, so that the plate is logically divided, that is, the plate model is divided into a plurality of drilling areas, rather than physically dividing the solid plate, that is, the solid plate is still a whole plate.
Optionally, the segmentation process specifically includes: w is the width of the plate, h is the height of the plate, x1Is the hole site coordinate x value, y1Is the hole site coordinate y value, h1Is the division height. And cutting the plate into two parts according to the height of the plate processing area, and then processing the hole position information on the plate. By a dividing height h1The original point of the y direction is, and then y-h of all hole site data on the upper plate1And the coordinate value in the x direction is unchanged. After the upper half plate is processed, the plate is rotated 180 degrees anticlockwise and then translated in the y-upper direction h1Up to h1The division line coincides with y equal to 0, and at the moment, the hole position coordinate needs to be recalculated with y2＝y1-h+h1，x2＝x1。
For each separated single plate, if an upper hole and a lower hole exist, the plate needs to be rotated by 90 degrees anticlockwise so as to adapt to the condition that the mechanical structure can only process horizontal left and right holes. When the plate specification is far larger than the multi-row drill machining area, the plate to be machined is divided into a first plate model and a second plate model which can be machined by the drill packets, so that the machining of the large-size plate is realized.
Alternatively, in order to optimize the number of steps, the first step of processing can be divided into three cases. Firstly, placing the plates according to the normal postures of the plates; secondly, turning the plate up and down, wherein the front drilling and packaging processing is changed into the back drilling and packaging processing, and the back drilling and packaging processing is changed into the front drilling and packaging processing (mainly for processing the condition that the number of the front processing holes is more than that of the back processing holes, because the number of the front processing drilling and packaging columns is different from that of the back processing drilling and packaging columns); and thirdly, the plate rotates to mainly process the situation that horizontal holes on the side surfaces (left and right) are processed together with the front surface or the back surface.
In the case of processing a single plate (including the case after the preceding cutting), in order to optimize the number of steps, two cases are considered. Firstly, if the upper hole and the lower hole exist, the upper hole and the lower hole are processed in a rotating mode, the holes on the front side and the back side are processed simultaneously, and when the upper hole and the lower hole are processed, the remaining holes on the front side and the back side are processed; and secondly, in the same way as the first situation, after the upper hole and the lower hole are machined, the first way is not rotated, the plate posture is kept until the machining is finished, and after the machining is finished, the plate posture is rotated again to the original plate posture for continuous machining. After each case is processed, the final process numbers of the two cases are compared, and fewer processes are selected.
In an embodiment, if the target drill-bit covering model collides with another drill-bit covering model, the method further includes the following step of moving the to-be-processed hole site data corresponding to the target drill-bit covering model to a next process until the target drill-bit covering model does not collide with another drill-bit covering model in the same process, and obtaining process information of the numerical control multi-row drill: and synchronizing the position relation between the drill package model and the plate model to be processed in each procedure.
In this embodiment, the position of the drill pack is adjusted so as not to move as much as possible based on the initial position. Optionally, the adjustment mode 1 is that the plate and the drill package move synchronously, so that the position relationship between the drill package and the plate is not changed; the adjustment mode 2 is an integer multiple of the distance between the moving holes of the drill package (when the drill package can process the corresponding holes), so that even if the drill package moves, the processing relation is still unchanged, and the original holes can still be processed after the drill package moves. By synchronizing the position relation between the drill bag model and the plate model to be processed in each procedure, the change of the drill position in each procedure is ensured to be minimum, so that the processing procedures are reduced, and the processing efficiency is improved.
