The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating embodiments of the invention, are given by way of illustration and explanation only, not limitation.
Fig. 1 is a flow chart of a method for secondary development of mass assembly bolts by three-dimensional software according to an embodiment of the invention. In this fig. 1, the method may include:
in step S10, acquiring an assembly part to be assembled, a bolt type and an installation surface contacted with a bolt cap of a bolt, which are input by a user;
in step S11, a detailed information list of the bolt and pin library is acquired;
in step S12, a hole data list of the assembled parts is obtained through the geometric topological relation;
in step S13, an installation Kong Dianwei is acquired on the installation face input by the user;
in step S14, a correspondence between the mounting hole point position and the fitting part is determined;
in step S15, a bolt is selected and inserted according to the correspondence and the maximum distance between the mounting hole point and the part hole of the assembly part to complete the bolt assembling operation.
In this embodiment, the bolt is used to insert the part where the mounting surface is located from the mounting surface and pass through the part hole in the fitting part, thereby fixing the part where the mounting surface is located and the fitting part.
In this fig. 1, step S10 may be used to acquire a fitting part, a bolt-type mounting surface, input by a user. This step S10 may be to create an interactive interface (for example, fig. 2) first to guide the user to input the information, and after inputting the information, the input information may be input into the background to obtain a file of the input information in the system. Specifically, the method may be an execution program main function OKAction (), and acquires a corresponding bolt library address according to a bolt type; the bolt number list _ listBoltPartNum, the bolt nominal diameter list _ listboltportdiameter, and the bolt length list _ listBoltLength are read from the last segment of the bolt library address. An example of the resulting list is shown in fig. 3.
Step S11 is for acquiring a detailed information list of the bolt and pin library. In particular, this step S11 may comprise a method as illustrated in fig. 4. In fig. 4, the step S11 may include:
in step S20, a directory in which a dll file of the three-dimensional software is located is acquired.
In step S21, the item configuration folder is obtained in the directory where the dll file is located, that is: the configuration folder path = dll directory + "bin \\ jeeprojects config".
In step S22, an item path is acquired in the item configuration folder according to the item number.
In step S23, a bolt library address save file is acquired in the project path, that is: the library address saved file path = project path + "\ \3D \ \ fastener".
In step S24, the detailed information list of the bolt and pin library is read from the bolt library address saving file, that is: the bolt library information list vecboltlnfo (bolt type + corresponding bolt library address) is read from fastener.
Step S12 is used for obtaining a hole data list of the assembly parts through geometric topological relations, namely determining that the part holes on the assembly parts are possible to be assembled and summarizing the part holes into a hole data list. For the method of determining the part hole, there may be a step as shown in fig. 5. In this fig. 5, the method may include:
in step S30, a topological entity list of the assembled parts is acquired;
in step S31, traversing each part in the topology entity list to obtain a corresponding two-dimensional CATFace list;
in step S32, traversing each two-dimensional CATFace in the two-dimensional CATFace list, and determining whether the two-dimensional CATFace is an inner cylindrical surface;
in step S33, in the case where the two-dimensional CATFace is determined to be the inner cylindrical surface, the centers and the axial directions of the upper arc and the lower arc of the inner cylindrical surface are obtained to obtain the hole data list.
In addition, if the central angle of the upper arc or the lower arc is less than 90 degrees, it means that the arc is not a part hole, and therefore, no calculation may be performed.
And step S13 is used for acquiring mounting hole positions on the mounting surface input by the user. Specifically, the step S13 may be to obtain the center and the diameter of the circle where each mounting hole point on the mounting surface is located, so as to form a center list and a diameter list.

in step S41, the position of the part where the mounting hole point is located in the global environment and the corresponding inverse matrix are obtained;
in step S42, the position of the assembled part in the global environment is acquired;
in step S43, the position of the part hole where the part is assembled is converted into the coordinate system of the part where the mounting hole site is located. The conversion matrix = mounting surface position inverse matrix and mounting part position matrix, and the coordinates after conversion = coordinates before conversion matrix.
In step S44, the hole data list of the assembled part is traversed to determine whether the axial distance between the part hole and the mounting hole point is less than or equal to a first preset value. Wherein, the first preset value may be preferably 0.01;
in step S45, under the condition that it is determined that the axial distance between the part hole and the mounting hole point is smaller than or equal to the first preset value, it is determined whether an axial included angle between the mounting hole point and the upper arc or the lower arc of the part hole is smaller than a second preset value. Wherein, the second preset value can be 5 °;
in step S46, when it is determined that the axial included angle between the mounting hole point location and the upper arc or the lower arc of the part hole is smaller than the second preset value, the mounting hole point location is matched with the part hole.
Further, in this embodiment, it is considered that after the method matching as illustrated in fig. 6, there may be a case where the same part hole is matched to a plurality of mounting hole sites. Then, in the case where the same part hole is matched to a plurality of mounting hole positions, the mounting hole position having the smallest axis distance may be selected to be matched to the part hole. In addition, in order to distinguish the threaded holes and the pin holes, the diameters of the part holes can be obtained under the condition that the positions of the mounting holes are matched with the part holes; and traversing the detailed information list of the bolt and the pin library to judge whether the difference between the diameter of the part hole and the diameter of the pin is less than or equal to a third preset value. Wherein the third preset value may be 0.001. Determining the part hole as a pin hole under the condition that the difference between the diameter of the part hole and the diameter of the pin is smaller than or equal to a third preset value; otherwise, it can be determined as a threaded hole.
And S15, selecting and inserting the bolt according to the corresponding relation and the maximum distance between the mounting hole point position and the part hole of the assembly part so as to finish the bolt assembly operation. In particular, this step S15 may comprise a method as illustrated in fig. 7. In fig. 7, the step S15 may include:
in step S50, a corresponding bolt diameter is searched in the detailed information list according to the diameter of the threaded hole, and a bolt set corresponding to the bolt diameter is obtained;
in step S51, the maximum distance between the mounting hole point and the part hole is determined; the maximum distance is calculated according to equation (1),
maximum distance = part hole length + length of mounting hole point + shortest distance between part hole and mounting hole point, (1).
In step S52, the corresponding bolt is found in the bolt set according to the maximum distance.
For the operation of mounting the bolt in this step S15, there may be a step as shown in fig. 8. In fig. 8, the step S15 may include:
in step S60, a plane is created with the mounting point location as the origin and the axial directions of the mutually matched mounting point location and the part hole as the normal lines;
in step S61, a mathematical coordinate system StdMathAxis of the mounting surface is established on the created plane;
in step S62, a standard axis coordinate system spStdAxisSystem and a mathematical axis coordinate system STDMathAxis of the bolt are acquired;
in step S63, the mathematical axis coordinate system of the bolt and the mathematical axis coordinate system of the mounting surface are subjected to a conversion operation, that is: stdaxistsystrans = catmathtransformat (STDMathAxis, catnathioijk) = catmathtransformat (catnathioijk, stdmanthaxis);
in step S64, the position of the bolt in the global environment is acquired and set according to the result after the conversion operation, that is: absStdPos = surparttran @ localsttmathtrans @ stdaxissytrans (surparttran is the location of the part on which the mounting face is located in the global environment)
In step S65, bolts are inserted into the mounting hole sites and the part holes depending on the positions. After the conversion of the coordinate system is completed, the directions of the mounting hole point, the bolt and the part hole at this time are completely aligned, so that the step S65 can insert the bolt into the mounting hole point and the part hole directly according to the positional relationship.
