Description

Technical Field

[0001] The utility model belongs to the technical field of sample auxiliary marking devices, in particular to an auxiliary marking device for aviation aluminum alloy detection. Background Art

[0002] High-end aluminum alloy materials for aviation usually have high comprehensive performance. They not only require high strength and good toughness, but also require long service life, excellent corrosion resistance and other characteristics. Therefore, aviation aluminum alloys require a lot of inspection items before leaving the factory. However, the same inspection items also require different inspection directions. At the same time, different inspection items require different sampling locations. For example, greenhouse tensile performance requires testing in the longitudinal, transverse and height directions. Exfoliation corrosion performance requires sampling at 1 / 10 of the thickness of the plate. Fatigue performance sampling requires sampling at the center of 1 / 2 thickness of the plate. Therefore, various performance tests of aviation aluminum alloy plates must ensure the accuracy of the sampling position, otherwise the plate performance test data will be distorted and fail to meet the requirements of the performance assessment indicators, which will directly affect the engineering application of the product. Therefore, the marking process of the plate sampling position before testing is crucial.

[0003] At present, the marking operation of the line position of the aviation aluminum alloy plate inspection project has always been done by manually calibrating the center of the sample sampling position with a ruler, then marking according to the size of the sample blank, sawing the blank according to the marking position in the sawing machine process, and finally using a lathe, drilling machine or milling machine to process the blank for final inspection sample. Since there are more than ten inspection items and multiple samples are required, during the marking process, the sample maker needs to calibrate the centers of different thicknesses of multiple samples multiple times according to the different sampling position requirements of different inspection items, which greatly increases the time cost and labor cost of sample marking, and there is also the situation that the sample maker marks inaccurately. Therefore, in order to solve the current cumbersome process of marking in the early stage and avoid the possible occurrence of inconsistency and inaccuracy in marking by different sample makers, it is urgent to design an auxiliary marking device for aviation aluminum alloy inspection.
