Description
Technical Field
The utility model relates to an inspection method after riveting and assembling of aviation products, in particular to a method for inspecting the quality of a common riveting pier head.
Background
In the assembly and manufacturing process of aviation products, common riveting is the most widely applied connection mode, and has the characteristics of simplicity in operation, difficulty in loosening and the like. To obtain the reliability of connection, quality inspection is required to be performed on a plurality of elements before and after riveting, and the riveting quality of a product is ensured, wherein the quality of a rivet pier head is the most important inspection element, in the inspection process, the diameter and the height of the rivet pier head are required to be measured, two measured values simultaneously meet the technical standard range, namely, the rivet pier head is judged to be qualified, and any one measured value or two measured values exceed the technical standard range, namely, the rivet pier head is unqualified. At present, the quality inspection of the rivet pier head mainly adopts two modes, one mode is quantitative inspection, namely: and checking by using a general checking and measuring tool, and comparing the measured data with standard data to judge whether the data are qualified or not. In operation, a vernier caliper is generally used for measuring, the diameter of the rivet pier head is firstly measured by using a clamping foot of the vernier caliper and recorded, then the height of the rivet pier head is measured by using a depth gauge of the vernier caliper and a main ruler and recorded, and finally the recorded numerical value is compared with the standard numerical value to judge whether the rivet pier head is qualified or not. The method has the advantages that the real size of the real object can be obtained, the detection efficiency is low, the method cannot adapt to batch inspection, the method is greatly influenced by human factors, and errors are easy to occur in aspects of tool selection and use, reading, recording and the like. Another way is qualitative inspection. Namely: and (3) not measuring specific values, and judging whether the two dimensions of the diameter and the height of the rivet pier head are between the maximum value and the minimum value or not. Qualitative inspection is a commonly adopted distinguishing mode in engineering practice, and currently, a widely used general inspection tool is a rivet gauge, each rivet gauge corresponds to a diameter rivet, and one rivet gauge is provided with three measuring heads, namely a maximum diameter of the rivet head, a minimum diameter of the rivet head and a maximum height of the rivet head, and the defect that each inspection of one pier head needs to be measured three times is that is, the maximum diameter of the pier head, the minimum diameter of the rivet head and the maximum height of the rivet head. The measuring workload is large, the efficiency is low, sliding measurement is needed in the implementation process, and the surface scratch of the part is easy to cause.
The finding of related patents still has drawbacks and deficiencies. The first patent is: the utility model relates to a rivet pier size inspection tool (patent number CN 216846015U), which belongs to a qualitative measuring tool, and can measure three elements by one action, but has the defects that the height of a rivet pier still needs to be manually judged, particularly when the height of the rivet pier is close to a standard limit value, the manual judgment error is large, and the accuracy is low; and then as the second patent: the rivet pier size measurer (patent number CN 214582940U) also belongs to a qualitative measuring tool, has the advantages that rivet gauges with different diameters are integrated into one measuring tool, so that the replacement of the measuring tool due to different rivet diameters is avoided, and has the defects that each rivet pier still needs to be measured for three times, the measuring efficiency is low, and the highly integrated tool is easy to be confused in use, so that misjudgment is caused; as another example, patent No.: the method for detecting the quality of the riveting pier head of the airplane (patent number CN 113129268A) has the advantages that the quality defect of the rivet can be rapidly judged by utilizing the graph processing and the least square fitting circle principle without depending on artificial factors, the detection efficiency is improved, and the problem of manual judgment errors is solved. The method is suitable for quality inspection of rivet pier heads in open areas such as aircraft skins, and has certain limitation on non-open areas such as complex airframe structural areas and closed areas.
By analyzing the existing detection method and detection tool, the problems of large measurement workload, low measurement efficiency, easy part surface scratch in the measurement process, large influence of human subjective judgment and operation method factors, certain use limitation in non-open areas such as complex machine body structure areas or closed areas and the like exist, and the defects and adverse factors directly influence the product management and control capability and the inspection work efficiency.
