DETAILED DESCRIPTION

[0032] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0033] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0034] like Figures 1 to 6 As shown, a device for assisting a direct-reading spectrometer in component detection comprises a base 1 and an excitation platform 2, wherein the excitation platform 2 is detachably connected to the base 1;

[0035] The base 1 is provided with an excitation unit 3, and the excitation platform 2 is provided with a generating cover 31. The excitation unit 3 is set in the generating cover 31. The top of the generating cover 31 has an opening. The metal sample to be tested is placed in the opening and covers the opening. The metal sample to be tested generates characteristic spectral lines after being excited by the excitation unit 3.

[0036] It also includes a gas protection unit and an optical channel 5. The gas protection unit is used to provide a gas protection environment during the excitation process;

[0037] The characteristic spectrum generated in the generating cover 31 is introduced into the spectroscopic chamber of the direct reading spectrometer through the optical channel 5. After the spectrum is decomposed by the dispersion element in the spectroscopic chamber, the intensity of the selected internal standard line and analysis line is measured.

[0038] The excitation platform 2 has a cavity inside, and a refrigeration chamber is formed between the cavity and the generating cover 31. The refrigeration chamber also includes a water cooling unit, which is used to cool the refrigeration chamber to remove the heat generated by the excitation unit 3 during operation.

[0039] The water cooling unit includes a water inlet pipe 21 and a water outlet pipe 22 . The water inlet pipe 21 is connected to an external cooling water source. The water inlet pipe 21 and the water outlet pipe 22 are respectively arranged on opposite sides of the exciting platform 2 .

[0040] The gas protection unit includes an air inlet pipe 23 and an air outlet pipe 24. The air inlet pipe 23 is connected to an external argon gas source, and the air outlet pipe 24 is connected to an external vacuum pump to cooperate with the air inlet pipe 23 to exhaust the air in the generating cover 31.

[0041] The inner diameter of the air inlet pipe 23 is larger than the inner diameter of the air outlet pipe 24 .

[0042] A pressing unit is also provided, which includes a vertical rod 25 and a horizontal rod 26. The bottom of the vertical rod 25 is set on the base 1, and the top of the vertical rod 25 is rotatably connected to the horizontal rod 26. The end of the horizontal rod 26 away from the vertical rod 25 is also provided with a mounting hole 261. A vertical pressing rod 262 is provided in the mounting hole 261. The bottom of the pressing rod 262 has a rubber gasket 263 for pressing the metal sample to be tested downward to prevent the metal sample to be tested from having a gap with the opening at the top of the generator cover 31.

[0043] A tightening bolt 27 is further provided on the side of the clamping rod 262 , and the tightening bolt 27 is used to fix the position of the clamping rod 262 from the side.

[0044] The auxiliary metal plate 4 is provided with a receiving groove 41 for receiving the device under test. The shape of the receiving groove 41 matches the shape of the device under test. The auxiliary metal plate 4 is made of the same material as the device under test.

[0045] A through guide groove 11 is further provided on the base 1 , and a corresponding guide block 27 is provided at the bottom of the exciting platform 2 , and the guide block 27 extends deep into the guide groove 11 .

[0046] During use, the excitation platform 2 is first installed on the base 1. The excitation platform 2 and the base 1 are detachably connected, which facilitates the disassembly of the laser platform for equipment maintenance. At the same time, the excitation platform 2 of different materials can be replaced according to specific detection needs.

[0047] An excitation unit 3 is connected to the base 1. The excitation unit 3 adopts but is not limited to the same excitation unit 3 as the ARL direct-reading spectrometer produced by Thermo Corporation. It should be noted that the excitation principle of the excitation unit 3 for the element to be measured in this scheme is the same as that of the ARL direct-reading spectrometer. At the same time, how to introduce the characteristic spectral lines generated in the generating cover 31 into the spectrometer chamber of the direct-reading spectrometer through the optical channel 5 in this scheme, after the spectrum is decomposed by the dispersion element in the spectrometer chamber, the intensity of the selected internal standard line and the analysis line is measured also adopts the existing technology. This is not an innovative improvement of the present scheme. The present scheme is an improvement proposed for the problems existing in the same and similar models of equipment during the use of the ARL direct-reading spectrometer produced by Thermo Corporation.

[0048] Since the excitation unit 3 easily generates heat during operation, this solution optimizes the cooling unit, which specifically includes a water inlet pipe 21 and a water outlet pipe 22. The water inlet pipe 21 is connected to an external cooling water source. The water inlet pipe 21 ensures that the cavity of the excitation platform 2 is filled with cooling water. The cooling water wraps the generator cover 31, thereby achieving cooling of the generator cover 31 and the inside of the generator cover 31. The generator cover 31 is not connected to the interior of the cavity of the excitation platform 2.

[0049] At the same time, high-purity argon is required as a protective gas during the working process, so the technical solution is as follows: it includes an air inlet pipe 23 and an air outlet pipe 24, the air inlet pipe 23 is connected to an external argon gas source, and the air outlet pipe 24 is used to cooperate with the air inlet pipe 23 to discharge the air in the generating cover 31. At the same time, the inner diameter of the air inlet pipe 23 is larger than the inner diameter of the air outlet pipe 24 to improve the exhaust effect.

[0050] The pressing unit is designed to press the metal sample to be tested downward to prevent a gap between the metal sample to be tested and the opening at the top of the generator cover 31 .

[0051] In another embodiment, since the current direct reading spectrometer detection system is relatively complex, there are special requirements for the size and external dimensions of the metal sample to be tested, that is, the metal sample size is required to be a flat, clean, burn-free, and rust-free analysis surface with a diameter of 16 mm ≤ ≤ 75 mm and a thickness of 2 mm ≤ ≤ 80 mm (the diameter of the excitation point is 8 mm).

[0052] The analytical surface must be pre-processed by grinding and polishing to ensure that there is no air leakage between the metal sample and the analytical frame. Small nuts (8mm ≤ side length or height ≤ 16mm) cannot be tested on a direct reading spectrometer, forcing the use of other detection methods, which reduces work efficiency and increases production costs.

[0053] Therefore, in response to the above problems, the auxiliary metal plate 4 proposed in this solution solves the above problems. The specific solution is as follows: The design idea of ​​the auxiliary metal plate 4 takes into account that small-sized nuts cannot be processed into a plane with a diameter greater than 16 mm, but as long as the test sample meets the excitation point diameter ≥ 8 mm, and the inner wall of the tooling is sealed and there is no air leakage, it can be analyzed.

[0054] The auxiliary metal plate 4 is composed of a metal plate with an oblique groove, a matching sealing ring and a small-sized nut. According to the material and external dimensions of the small-sized nut, a metal plate with an oblique groove (the oblique groove size matches the external dimensions of the nut) and a thickness not greater than the thickness of the nut is made of the same material. The nut is placed in the oblique groove. Figure 1 As shown, in order to prevent air leakage, a sealing ring is used to seal the nut and the metal plate. With the help of the auxiliary metal plate 4, the chemical composition of the small-sized nut can be detected on the direct reading spectrometer.

[0055] The present invention is described in further detail below with reference to the accompanying drawings. Figure 7 This is a schematic diagram of the small-sized nut involved in this solution, where a, b, and c represent the side length, height, and thickness of the small-sized nut, respectively.

[0056] Figure 8 The schematic diagram of the oblique groove of the auxiliary metal plate 4 is shown in FIG. a and b represent the length and width of the oblique groove respectively. Figure 7 a and b correspond one to one and are equal in value;

[0057] Figure 9 The length of the middle auxiliary metal plate 4 is in the range of 40 mm to 70 mm and the value is greater than a, the width is in the range of 40 mm to 70 mm and the value is greater than b, and the height is consistent with the thickness c of the small-sized nut being measured.

[0058] The auxiliary metal plate 4 is made of the same material as the small-sized nut being tested. A metal plate with an oblique groove is fabricated based on the external dimensions of the small-sized nut. A quenching and tempering heat treatment is selected. The bottom surface of the metal plate with a hole (the length of the hole is equal to the side length of the small-sized nut) is ground and polished using a grinding wheel, sandpaper, or belt grinder, ultimately forming a flat, clean, burn-free, and rust-free analytical surface. A sealing ring is installed at the connection between the oblique groove and the small-sized nut to seal it. Finally, the small-sized nut in this tooling is aligned with the hole in the direct-reading spectrometer analysis frame for chemical composition testing.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and description of the present invention.
