Detailed Description
Example 1
With reference to fig. 1 to 5, the embodiment of the present invention discloses an interference inspection auxiliary system based on policy reconstruction, which includes an inspection policy fast setting module, an inspection result batch processing module, an interference position accurate positioning module, and an inspection report automatic generation module.
The inspection strategy quick setting module is used for setting an elimination part and an interference inspection strategy according to the characteristics of an inspected object, and a plurality of interference inspection strategies including the elimination part, a filtering condition and an additional condition are preset in the inspection strategy quick setting module. The excluded part means "determining and excluding parts not involved in the inspection in this inspection", the filtering conditions include "whether to ignore radial interference of the standard part in the inspection", "whether to ignore the excluded part in the inspection", "whether to consider the sub-assembly as a part in the inspection", "whether to ignore the nut part in the inspection", and the additional conditions include "whether the inspection object includes a facet", "whether the inspection object includes a facet group". The user carries out the configuration of the inspection strategy according to various preset inspection strategies and by combining the actual characteristics or the detection requirements of the object to be detected, the configured inspection strategy is sent to an external interference inspection module (in the embodiment, the interference inspection module carried by the ProE software is referred to), and the inspection range and the objects of the interference inspection module in the software filtered by the inspection strategy are reduced, so that the inspection time is shortened, and the inspection efficiency is improved.
The quick module that sets up of inspection strategy of this embodiment can interfere inspection strategy setting according to the characteristics of the object under inspection, through getting rid of the part, neglecting radial interference of standard component, seeing that the sub-assembly is the part, neglecting swivel nut part, including interference inspection strategy setting such as face group, the efficiency of interfering the inspection can improve 20%, the false alarm rate of interfering the inspection can reduce 80%, solve the low difficult problem that the practicality is poor of commercial interference inspection tool efficiency.
The phrase "identifying and excluding parts not involved in the inspection in this inspection" means that the inspection range of the parts not required to be involved in the interference inspection is excluded by a standardized simplified representation tool (ProE software in the present embodiment) outside the support system. Whether radial interference of the standard component is ignored during inspection is to ignore the radial interference volume of the standard component and an inspected object, if a plurality of interference volumes are within a normal range, the radial interference of the standard component is ignored, if the fit of a screw and a threaded hole is ensured, the radial interference exists between the screw and the threaded hole of a corresponding specification under a general condition, when the radial interference is within the normal range, the interference between the screw and the threaded hole is represented as false interference, when the radial interference of the standard component is ignored during inspection strategy configuration, a part of the false interference can be ignored, and the inspection efficiency is improved. Whether the sub-assembly is considered as a part during the inspection or not is characterized in that the sub-assembly is considered as a part by calling a commercial software standard module, only the interference between the sub-assembly and the part at the current level is inspected, and the parts inside the sub-assembly do not participate in the interference inspection, so that the inspection efficiency is improved. The "whether or not to ignore the excluded parts during the inspection" and the "whether or not to ignore the insert parts during the inspection" are both provided with a range of parts that do not need to be inspected, and the number of interference inspection objects is reduced, so that the search time can be reduced. Whether the inspection object comprises the facet or not and whether the inspection object comprises the facet group or not are determined to determine whether the interference inspection is carried out on the curved surface, and the efficiency is improved according to the range of the selected inspection.
Specifically, as shown in fig. 2, when performing interference check, the assembly model to be checked is opened, and in case of complete assembly of the model and no error, the interference check tool is started, and the interference check interface is entered, the user can quickly set an interface for clicking corresponding check strategy options in the interference check tool, firstly determine parts (parts are not excluded in the embodiment) not participating in the check, then select a filtering condition, the filtering condition selected in the embodiment is to ignore radial interference of the standard component, to view sub-assembly as parts, and to ignore barrel parts, none of the additional conditions is selected, and after selecting the filtering condition and the additional conditions, generate a filtered part name (number) and a filtered serial number, so that for easy viewing, the filtered model name and serial number respectively adopt the color of the corresponding filtering condition, so that the user can visually view the type and filtering reason of the filtering part, as can be seen in the embodiment, a total of 94 parts are filtered, as model M4X12_ GB818 is filtered due to radial interference of the standard component, and model a L6 _527 _626 is filtered due to sub-assembly as a part being ignored.
After the checking strategy is set in the checking strategy quick setting module, a user clicks a checking starting button, an interference checking module of the ProE software is called to formally carry out interference checking, and the time of the interference checking is related to the assembly size and the complexity to be checked. After the inspection is finished, an operator can quickly judge and set, the interference problems of the same type are quickly processed in batches, and the processing efficiency is improved. The inspection result batch processing module is used for classifying the inspection results, automatically gathering all interference between the same part and different parts, displaying the type of the interference, and selecting all corresponding interference results by clicking the interference items of a certain type of parts or the interference items of a certain type of interference by a user. The classification process mainly classifies the interference situations found by the inspection into the following categories: the method comprises the following steps of interference of fastener threads, interference caused by non-standard purchased part models, interference of interference fit, interference caused by the fact that modeling cannot completely simulate real conditions, interference caused by model simplification, interference caused by elastic deformation parts, interference of auxiliary parts (to be removed when the whole frame is debugged) with formal parts, interference of framework models and interference with cable models and the like.
The interference of the threads of the fastener passes through a radial interference volume between the screw and the threaded hole in the detection result, and if the radial interference volume falls within a normal range, the interference is expressed as the interference of the threads of the fastener; for interference between the shaft and the hole, if the radial interference between the shaft and the hole is within a normal range, interference fit interference is expressed; aiming at the problems that a purchased part model is not standard, modeling cannot completely simulate real conditions, the model is simplified, elastic deformation parts and screw sleeve parts interfere with a cable or framework model and the like, distinguishing is carried out according to the type of the model which specifically interferes.
As shown in FIG. 3, after inspection, 226 interference pieces are found, wherein the result of the interference inspection is classified according to the parts which have interference, for example, the part with the number A L _623_7803 has 1 interference with other parts, and the part with the number A L _061_3384 has 30 interference with other parts.
The interference position accurate positioning module corresponds interference items on the interface to the results of interference check of ProE software one by one, the interference position on the assembly can be positioned by clicking the interference items, two mutually-related parts are highlighted on the interface, and the interference position and the interference area are highlighted. The operator visually observes the interference check result according to the display of the module.
The inspection result automatic generation module comprises an interference inspection report template, and is connected with the inspection result batch processing module and a model database to be inspected outside the auxiliary system. The inspection report automatic generation module can automatically generate an interference inspection report for an interference processing result according to a pre-configured interference inspection template, and can hang the interference inspection report in a model accessory of an inspected object. The operator can click the corresponding buttons for generating the interference check report and hanging the interference check report menu to realize the corresponding functions. In the interference check report generated in this embodiment, the template includes the description of the interference condition and the corresponding interference amount, and an Excel format check report is generated.
The interference inspection auxiliary system based on strategy reconstruction adopts a characteristic identification technology to automatically eliminate thread interference of fasteners and the like, and realizes automatic grouping and filtering of inspection results; by adopting reconstruction strategies such as grading, partitioning, quick elimination and simplification, the problems of low speed, low efficiency, incapability of batch processing and the like of interference inspection are solved, and the efficiency and the practicability of the interference inspection are improved. The invention can improve the efficiency of interference check, reduce the false alarm rate of the interference check, quickly check the interference area, shorten the processing time of the interference check and automatically generate an interference check report according to the requirement.
