Description

Skin part quickly generates the modeling method of guide hole

Technical field

The present invention relates to a kind of modeling method, and in particular to a kind of skin part quickly generates the modeling method of guide hole.

Background technology

Skin part is the foreskin of the wallboard part and internal truss frame structure for constituting Aerodynamic Configuration of Aireraft.Covering bears air and moves Active force is delivered on connected fuselage wing skeleton after power effect, stress is complicated, in addition covering is directly contacted with the external world, institute It is good not require nothing more than skin material intensity height, plasticity, also require that surface is smooth, there is higher resistance to corrosion.At present, produced Skin part is mostly the skin part of single degree or Double curve degree, will to the accuracy of all kinds of structural elements modeling in forming process Ask also higher, guide hole just belongs to quasi-representative structural element therein.

During processing and manufacturing, needs output corresponding fabrication hole to skin part in each process stages, such as drawing Stretching shaping stage needs to drill milling location hole, needs to drill control hole and milling hole for hoist in lifting, needs in timing Drill K holes and assembling hole for hoist etc..When skin part is assembled, need with other parts, stringer, shear gusset plate etc. and carry out Connection, it is therefore desirable to the DA holes for assembly connection are drilled on the web surface of part.

DA holes are guide hole, needs output on skin part surface it is multiple, quantity typically all reach it is up to a hundred, DA hole Establishment is accomplished by once manual tap operation, takes and workload is very big.

Accordingly, it is desirable to provide a kind of new technical scheme is solving the above problems.

The content of the invention

The technical problem to be solved in the invention is to provide the modeling method that a kind of skin part quickly generates guide hole.Energy one It is secondary to output all guide holes, improve operating efficiency.

To solve the technical problem of the present invention, the technical solution used in the present invention is：

Skin part quickly generates the modeling method of guide hole, and it is comprised the following steps：

（1）Hole position center point coordinate is selected in Model Structure Tree；

（2）Perforate place face, user interface input aperture are selected on model geometric body；

（3）Perforate solid information is selected in Model Structure Tree, all guide holes are once outputed.

The modeling method is comprised the following steps that：

Step 1：Part digital-to-analogue is opened, complicated skin part process system is opened, while tool bar is opened, in click tools bar DA holes rapid modeling button, ejects " definition of DA holes " dialog box "；

Step 2：Select DA holes center point：A batch Sexual behavior mode or on model on skin part Model Structure Tree Select one by one, the center point information in all DA holes is selected in dialog box；

Step 3：DA holes place face is selected, the face at DA holes place is directly selected out on skin part process modeling；

Step 4：Input aperture, in the dialog box of DA holes definition aperture is input into, its data type can for int types or Double types；

Step 5：DA pore geometry bodies are directly selected out on skin model structure tree, selects work at present object to be that selection is opened DA pore geometry bodies, directly select current perforate entity on skin model structure tree, just can output on this solid all logical Hole；

Step 6：DA holes are created, after the every terms of information in required input dialogue frame is completed, the Create button is clicked on, i.e., All of DA holes can be outputed on structure tree.

Beneficial effects of the present invention：This method selects hole position center point coordinate in Model Structure Tree, in model geometric body Upper selection perforate place face, user interface input aperture, the information such as selection perforate solid in Model Structure Tree, once output All guide holes, it is ensured that the degree of accuracy of guide hole position, mitigate the workload of designer, improve operating efficiency.

Specific embodiment

Below in conjunction with the accompanying drawings the invention will be further described with specific embodiment.Following examples are merely to illustrate this It is bright, it is not limited to protection scope of the present invention.

As shown in 1a, Fig. 1 b, Fig. 2, the skin part of the present invention quickly generates the modeling method of guide hole,

（3）Perforate solid information is selected in Model Structure Tree, all guide holes is once outputed, so as to mitigate the work of designer Measure, improve operating efficiency.

（2）Perforate place face, user interface input aperture are selected on model geometric body；

（1）Hole position center point coordinate is selected in Model Structure Tree；

Shown in Fig. 2, the modeling method is comprised the following steps that：

Step 6：DA holes are created, after the every terms of information in required input dialogue frame is completed, the Create button is clicked on, i.e., All of DA holes can be outputed on structure tree.Wherein " perforate " feature is hung under the part geometry body of perforate object, other points Line auxiliary operation information all hangs over together and designs a model accordingly under node, selects to open 20 holes, all perforate behaviour in example Cancel button is clicked on after the completion of work can close box.

Step 5：DA pore geometry bodies are directly selected out on skin model structure tree, selects work at present object to be that selection is opened DA pore geometry bodies, directly select current perforate entity on skin model structure tree, just can output on this solid all logical Hole；

Step 4：Input aperture, in the dialog box of DA holes definition aperture is input into, its data type can for int types or Double types；

Step 3：DA holes place face is selected, the face at DA holes place is directly selected out on skin part process modeling；

Step 2：Select DA holes center point：A batch Sexual behavior mode or on model on skin part Model Structure Tree Select one by one, the center point information in all DA holes is selected in dialog box；

Step 1：Part digital-to-analogue is opened, complicated skin part process system is opened, while tool bar is opened, in click tools bar DA holes rapid modeling button, ejects " definition of DA holes " dialog box "；

In Fig. 2, according to part archetype, position of opening center reference point, the position of opening plane of reference are then selected, selected Select the point on curved surface after position of opening center reference point successively, cross the normal vector line that point is done on curved surface, determine pore size, It is determined that current perforate object, until the DA holes of all same sizes on curved surface are outputed, if not meeting process modeling requirement return Part archetype restarts.

This method selects hole position center point coordinate in Model Structure Tree, on model geometric body select perforate place face, User interface is input into aperture, selects the information such as perforate solid in Model Structure Tree, once outputs all guide holes, it is ensured that lead The degree of accuracy of hole site, mitigates the workload of designer, improves operating efficiency.
