Embodiment
Referring to accompanying drawing, embodiment is that to detect with the shot-peening of the outer wing wallboard of certain type aircraft be that example is described in further details the present invention, and it is as follows to detect model specific design manufacture process:
The outer wing wallboard material of this aircraft is the 7150-T7751 aluminium alloy, therefore, detects model and also uses above-mentioned material to manufacture and design with can best simulation panel surfaces quality.
The first step is to analyze the wallboard one-piece construction, and design detects the version of model;
This outer wing wallboard is carried out structure analysis, and this wallboard has following several configuration state: 1. thin and thick is alternate, the abrupt changes in thickness structure; 2. thickness slowly changes, two-way thickening degree structure; 3. " ⊥ " shape stud structure; 4. " worker " font stud structure; 5. mouthful mount structure etc.
The above five kinds of structures of comparative analysis can be divided into it two big classes: the one, 1. 2. 5. being the web plane structure of representative; The 2nd, with 3. 4. structure be the surperficial stud structure of representative.More than two kinds of feature structures can represent all contour structures of wallboard substantially, the basic structure that then detects model is that the basis is designed with above two kinds of feature structures, ignore the influence of wallboard profile curvature and thickening degree, finally draw two kinds of basic structures that detect model: slab construction, " worker " font stud structure.
Concrete structure as shown in the figure.The gauge that slab construction detects model 1 is prototype with wallboard web thickness full-size, and stud structure detection model 3 is prototype with wallboard stud full-size(d), and the control zone area size is self-defined, selects OK range.
What be worth emphasizing is that described slab construction detects the maximal value that the thickness of model is preferably got the wing wallboard web thickness, the maximal value that the thickness of described stud structure detection model is preferably got wing wallboard stud thickness.
Second step was to analyze wing wallboard shot-blast process method and parameter, formed the shot-peening parameter combinations of a plurality of standards according to different shot-blast process methods and parameter combinations;
Wallboard is owing to the difference of its structure, size, profile curvature, and its shot-blast process method and parameter also have very big-difference, and the shot-blast process of wallboard all will determine that a cover is fit to the shot-blast process parameter of this wallboard through work such as experiment sieving and torture tests usually.
For example embodiment outer wing wallboard shot-peening technological method for processing has three kinds, comprises contour peening, ultrasound wave school shape, shot peening strengthening.Zones of different at wallboard forming process median ventral plate shows as different process combinations again, mainly contains contour peening+shot peening strengthening, contour peening+ultrasound wave school shape+shot peening strengthening, the shape+shot peening strengthening of ultrasound wave school.Can determine that thus processing detects the employed technological method for processing combination of model and has three kinds: 1. contour peening+shot peening strengthening; 2. contour peening+ultrasound wave school shape+shot peening strengthening; 3. ultrasound wave school shape+shot peening strengthening.
Simultaneously, use with a kind of shot-blast process method carry out shot-peening processing the time, because therefore the difference of the panel surfaces quality that the shot-peening parameter difference of using also can cause also be required to be every kind of shot-blast process method and select suitable shot-peening parameter to detect the processing of model; When the shot-peening parameter is selected, be that standard is selected can panel surfaces being produced maximum compressive residual stress.Be example with the contour peening, carry out shot-peening with a kind of bullet and add man-hour when using that employed pressure is more big, speed is more little, and the more little residual compression stress that then produces in panel surfaces of flow is more big.
Analyze above-described embodiment outer wing wallboard shot-blast process method and parameter, form the shot-peening parameter combinations of four standards according to different shot-blast process methods and parameter combinations;
1. ASH660 bullet shaping+ASH230 bullet is strengthened;
2. ASH660 bullet shaping+Ф 3mm striker ultrasound wave school shape+ASH230 bullet is strengthened;
3. ASH660 bullet shaping+Ф 4mm striker ultrasound wave school shape+ASH230 bullet is strengthened;
4. Ф 1.2mm striker ultrasound wave school shape+ASH230 bullet is strengthened.
In the enforcement, the upper limit of preferably getting the shot-blast process parameter is formed the shot-peening parameter combinations of standard.
These four kinds of parameter group are closed formation to detecting the processing technology of model, therefore will detect the model surface and be divided into four zones and process.
The 3rd step was that described slab construction model and stud structure model are divided into four relatively independent model districts, the shot-peening parameter combinations of the corresponding standard in each model district;
As shown in the figure, the surface working that slab construction is detected model 1 becomes four independently dull and stereotyped model districts 2; The surface working of stud structure detection model 3 is become four independently stud model districts 4.In the enforcement, by the form of processing groove different models is separated the abscission zone branch.
The 4th step be adopt standard described in above-mentioned second step respectively the shot-peening parameter combinations respectively in shot-peening processing slab construction model and the stud structure model corresponding model district form and detect model;
By four kinds of independent standard shot-peening parameter group four model districts of inspection template are carried out independent processing, formed four independently shot-peening model districts at inspection template.
The 5th step was to detect the detection model that is processed to form by the 4th step of above-mentioned steps according to the inspection specifications after the processing of wing wallboard shot-peening;
Pass through above-mentioned steps, just can obtain a kind of wing wallboard bead blasted surfaces quality testing model, this detection model comprises a slab construction and detects model and a stud structure detection model, detect model in slab construction and be respectively equipped with different detection model districts with stud structure detection model, this detection model district carries out shot-peening by different shot-peening parameter combinations to be processed to form, and this shot-peening parameter combinations is corresponding to the technological parameter of wing wallboard being implemented shot-peening.
In the enforcement, be preferably on the body that detects model fixing by model nameplate 5, model nameplate 5 be used for record detect model distinctive information, with in preventing from using with wrong.
Final step is exactly the surface quality that adopts after the inspection template of above-mentioned steps five acceptance(check)s detects the processing of wing wallboard shot-peening.
According to the listed step of technique scheme, be determined to the surface quality control board that produces finished product, finishes inspection and acceptance from selection, structure analysis, process selection, parameter, because itself surface state has reached the critical conditions of wallboard inspection specifications and can represent the optional position structure of wallboard substantially, can directly use it to carry out the panel surfaces status detection.With its directly and shot-peening squab panel surface compare, observe difference between the two, be merely able to allow panel surfaces to have than the better surface state in control board surface, can illustrate that wallboard shot-peening rear surface state adheres to specification, otherwise expression panel surfaces quality does not satisfy acceptance requirement.
This kind detection method can reduce the artificial subjective factor of wallboard shot-peening processing rear surface quality testing, and the accordance of objective evaluation wing wallboard bead blasted surfaces quality becomes a kind of test stone that surface quality detects; Can not produce loss in the complete convenient management of surface quality control board and the use, have longer persistence.
