Embodiment Construction
[0018] Such as Figure 1 to Figure 3 As shown, this embodiment provides a thin-section sample fixture for direct-reading spectral analysis, including a metal tube 1, a metal cover 2, a first metal adjustment screw, a U-shaped metal clamp 4, and a second metal adjustment screw. In the example, the first metal adjusting screw is the thumb screw 3 , and the second metal adjusting screw is the set screw 5 . The thumb screw 3 is convenient for the operator to adjust the position of the thin sheet metal sample 6 by screwing the depth of multiple adjustment thumb screws 3 into the metal tube 1, so as to adjust the position of the thin sheet metal sample 6 on the excitation platform of the direct reading spectrometer . In this embodiment, the pipe wall of the metal pipe 1 is provided with four first threaded holes, and the four first threaded holes are arranged at equal intervals on the same plane. The synchronous screwing in of the thumb screws 3 can make the clamping of the thin s...

The invention provides a thin-slice sample clamper for direct-reading spectrum analysis. The thin-slice sample clamper comprises a metal pipe, first metal adjusting screws, U-shaped metal clips, second metal adjusting screws and a metal cover, wherein the pipe wall of the metal pipe is provided with a plurality of first threaded holes, the first metal adjusting screws are connected inside the first threaded holes, one end of the first metal adjusting screw is connected to the middle position of the U-shaped metal clip, the upper end positions of the U-shaped metal clips are provided with second threaded holes, the second metal adjusting screws are connected inside the second threaded holes, and the metal cover covers the upper end of the metal pipe. According to the present invention, thethin-slice sample clamper has advantages of simple structure and convenient operation, and can clamp the thin-slice-like metal sample with the thickness of less than 2 mm; and the thin-slice-like metal sample with the thickness of less than 2 mm is subjected to excitation test with a direct-reading spectrum analyzer, wherein the test process is safe, and the test result is accurate.
Description
technical field [0001] The invention relates to the technical field of direct-reading spectral analysis, in particular to a thin-section sample fixture for direct-reading spectral analysis. Background technique [0002] In the process of composition analysis of metal samples, direct-reading spectrometer is generally used for excitation test. However, since the direct-reading spectrometer requires the thickness of the metal sample to be greater than 2 mm, for a thin metal sample less than 2 mm, it is easy to break down when excited, the test process is unsafe and the result is inaccurate, so the direct-reading spectrometer cannot be directly used for measurement. If chemical analysis is used, not only the required time is long, but also the cost is high. [0003] The Chinese patent literature with the notification number CN201340387 discloses a spectral standard sample clamp, which is mainly used to hold spectral standard samples with a thickness less than 10 mm. Several thr...
