The direct-reading spectrometer comprises an instrument body, an excitation table arranged on the instrument body and a spark excitation source. The work fixture for testing multiple-structure samples comprises a fixing structure. The fixing structure comprises a fixing column arranged on the top of the excitation table. A first threaded rod is welded to the top of the fixing column. By arranging the fixing structure, a pushing structure and a limiting assembly, the irregular sample is preliminarily fixed by the threaded column.

Finally, the irregular sample is extruded and fixed by the downward extruding force of the extruding rod and the elastic force of the rubber sleeve, so that the subsequent operation of the irregular sample by the spark excitation source is facilitated.

Description

Technical Field

[0001] This invention relates to the technical field of direct-reading spectrometers, specifically to a tooling fixture for testing multi-structure samples using a direct-reading spectrometer. Background Technology

[0002] A direct-reading spectrometer is an instrument that uses an electric arc or spark to excite a sample to generate a characteristic spectrum. After the spectrum is dispersed by an optical system, the signal is converted by a detection system, and the data is processed by a data system, it can quickly and accurately analyze the content of metallic and some non-metallic elements. It features fast analysis speed, high precision, and wide element coverage, and is widely used in metallurgy, military industry, quality inspection and other fields.

[0003] In the detection process of direct-reading spectrometers, the excitation stage, spark excitation source, and tooling fixtures are key components to ensure detection stability and data accuracy. Currently, most mainstream fixture designs are designed for regular metal block samples such as cylindrical shapes. However, in actual detection scenarios, there are a large number of irregular metal samples with irregular shapes and multiple structures. Existing fixtures are difficult to achieve stable clamping and positioning of such samples, which can easily lead to sample displacement and unstable discharge during excitation, thereby affecting the reliability of detection data and failing to meet diverse detection needs.

[0017] In a preferred embodiment, a rotating block is welded to the end of the threaded post away from the rubber pad.

[0018] The technical effect of adopting the above-mentioned further solution is that by setting a rotating block, it is easier to rotate the threaded column.

[0019] In a preferred embodiment, the auxiliary positioning component includes a bracket detachably mounted on the top of the adjustment plate and an iron rod welded to the top of the extrusion rod.

It offers the following advantages: By setting up a fixed structure, a pushing structure, and a limiting component, the irregular sample is initially fixed with the help of a threaded column. Then, the height of the adjusting plate is adjusted according to the height of the irregular sample. Subsequently, the pushing stage is moved to move the irregular sample so that the top of the irregular sample contacts and squeezes the rubber sleeve. At this time, the squeezing rod rotates. Finally, the irregular sample is squeezed and fixed by the downward squeezing force of the squeezing rod and the elasticity of the rubber sleeve, which facilitates the subsequent operation of the irregular sample by the spark ignition source. By setting up an auxiliary adjustment structure, one side of the irregular sample is in contact with the end of the spark ignition source. Depending on the height of the irregular sample, the extrusion rod is moved by rotating the second threaded rod, thereby achieving the purpose of easily handling different irregular sample heights. When testing columnar samples, the second bolt can be directly screwed onto the push platform for fixation. Then, the columnar sample is pushed onto the push platform, and the top of the columnar sample contacts and squeezes the rubber sleeve. The downward squeezing force of the squeezing rod and the elasticity of the rubber sleeve are used to squeeze and fix the columnar sample, which facilitates the subsequent operation of the columnar sample by the spark ignition source. This reduces the common testing steps for columnar samples and thus reduces the cumbersomeness of common columnar sample operations. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] like Figures 1-7 As shown, this embodiment provides a technical solution: a fixture for testing multi-structure samples using a direct-reading spectrometer. The direct-reading spectrometer includes an instrument body 1, an excitation stage 2 mounted on the instrument body 1, and a spark excitation source 7. The fixture for testing multi-structure samples includes a fixing structure 3. The fixing structure 3 includes a fixing column 301 mounted on the top of the excitation stage 2. A first threaded rod 302 is welded to the top of the fixing column 301. An adjusting plate 303 is adjustablely mounted on the first threaded rod 302. A rotating rod 306 is rotatably connected to the adjusting plate 303. A pressing rod 307 is welded to the rotating rod 306. A rubber sleeve is detachably fitted on the outer side of the bottom end of the pressing rod 307. The sleeve 308 has a lower nut 304 and an upper nut 305 threadedly connected to the first threaded rod 302. The adjusting plate 303 is located between the lower nut 304 and the upper nut 305. It should be noted that, firstly, the lower nut 304 is screwed onto the first threaded rod 302, then the adjusting plate 303 is fitted onto the first threaded rod 302, and then the upper nut 305 is screwed onto the first threaded rod 302. This causes the upper nut 305 and the lower nut 304 to press against the adjusting plate 303, thereby fixing the height of the adjusting plate 303. At the same time, by adjusting the upper nut 305 and the lower nut 304, the height of the adjusting plate 303 can be easily adjusted. The excitation stage 2 is equipped with a pushing structure 4, which includes two pushing platforms 402 and a sliding groove 401 formed on the excitation stage 2. The two pushing platforms 402 are detachably connected. The bottom end of each of the two pushing platforms 402 is provided with a slider 403 that is slidably connected to the sliding groove 401. The excitation stage 2 is equipped with a limiting component 5, which includes four positioning plates 501. The four positioning plates 501 are connected to each other by a connecting rod 502. A threaded post 503 is threadedly connected to the positioning plate 501. A rubber pad 504 is installed at one end of the threaded post 503. Two of the positioning plates 501 are detachably connected to the pushing platform 402. Specifically, according to the above technical solution, firstly, the limiting component... 5. The sample is assembled on the push stage 402. Then, the irregular sample is placed on the push stage 402. Then, the threaded column 503 is rotated, which causes the rubber pad 504 to squeeze the irregular sample, thereby achieving the purpose of initially fixing the irregular sample. Then, the height of the adjusting plate 303 is adjusted according to the height of the irregular sample. Then, the push stage 402 is moved, which causes the irregular sample to move, so that the top of the irregular sample contacts and squeezes the rubber sleeve 308. At this time, the squeezing rod 307 rotates. Finally, the irregular sample is squeezed and fixed by the downward squeezing force of the squeezing rod 307 and the elastic force of the rubber sleeve 308, which facilitates the subsequent operation of the spark ignition source 7 on the irregular sample.

[0030] Going a step further, such as Figure 5 As shown: The spark ignition source 7 is detachably installed between the two pushers 402. It should be noted that each of the two pushers 402 has a mounting groove on its opposite side, and a rubber sheet is installed in the two mounting grooves. The spark ignition source 7 is pressed between the two pushers 402, and the two pushers 402 are connected by screws. In addition, the spark ignition source 7 is fixed between the two pushers 402 by the rubber sheet.

[0031] Going a step further, such as Figure 3 As shown: A fixing plate 309 is movably fitted to the outer side of the rubber sleeve 308. A first bolt 310 is movably inserted into the fixing plate 309. The first bolt 310 is threadedly connected to the extrusion rod 307. It should be noted that because the rubber sleeve 308 will be used for a long time and is in frequent contact with the sample, the rubber sleeve 308 is easily worn. Therefore, by replacing the rubber sleeve 308, the rubber sleeve 308 is extruded and fixed by the fixing plate 309 and the first bolt 310.

[0032] Going a step further, such as Figure 1As shown: A second bolt 404 is movably inserted on the push stage 402. The second bolt 404 is threadedly connected to the excitation stage 2. It should be noted that when testing irregular samples, the second bolt 404 can be unscrewed to ensure that the push stage 402 can slide normally. When testing columnar samples, the second bolt 404 can be directly screwed on to fix the push stage 402. Then, the columnar sample is pushed on the push stage 402, and the top of the columnar sample contacts and squeezes the rubber sleeve 308. At this time, the extrusion rod 307 rotates. Finally, the columnar sample is squeezed and fixed by the downward extrusion force of the extrusion rod 307 and the elasticity of the rubber sleeve 308, which facilitates the subsequent operation of the spark excitation source 7 on the columnar sample, thereby reducing the testing steps for columnar samples and reducing the complexity of the operation.

[0033] Going a step further, such as Figure 1 and Figure 6 As shown: A mounting plate 506 is installed on the bottom of both positioning plates 501. A third bolt 507 is movably inserted on the mounting plate 506. The third bolt 507 is threadedly connected to the push table 402. The mounting plate 506 and the third bolt 507 facilitate the disassembly and assembly of the limit component 5.

[0034] Going a step further, such as Figure 5 As shown: A rotating block 505 is welded to the end of the threaded post 503 away from the rubber pad 504. The use of the rotating block 505 makes it easy to rotate the threaded post 503.

[0035] Going a step further, such as Figure 7 As shown: An auxiliary positioning component 6 is provided on the adjustment plate 303. The auxiliary positioning component 6 includes a bracket 601 detachably installed on the top of the adjustment plate 303 and an iron rod 604 welded to the top of the extrusion rod 307. A U-shaped block 602 is detachably installed on the bracket 601. The outer side of the iron rod 604 is in contact with the inner side of the U-shaped block 602. An electromagnet 603 is detachably installed on one side of the U-shaped block 602. The magnetic end of the electromagnet 603 is close to the iron rod 604. According to the above technical solution, specifically, the electromagnet 603 is pre-activated. After the extrusion rod 307 is used and rotated, the iron rod 604 enters the inner side of the U-shaped block 602. The electromagnet 603 presses and fixes the iron rod 604, thereby achieving further positioning of the extrusion rod 307 to achieve the effect of sample positioning stability. Among them, the surface of the iron rod 604 is coated with water-based acrylic polyurethane topcoat of model HS-808 produced by Chengdu Haoshi Paint Co., Ltd.

[0036] Going a step further, such as Figure 1 and Figure 2As shown: The auxiliary adjustment structure 8 includes a slide rail 801 mounted on the excitation stage 2, a fixed column 301 slidably connected to the slide rail 801, and a second threaded rod 802 rotatably connected to the slide rail 801. The outer side of the second threaded rod 802 is threadedly connected to the inner wall of the fixed column 301. According to the above technical solution, specifically, ensuring that one side of the irregular sample is in contact with one end of the spark excitation source 7, then, depending on the height of the irregular sample, the second threaded rod 802 is rotated to drive the fixed column 301 to move. The movement of the fixed column 301 drives the movement of the adjustment plate 303, and the movement of the adjustment plate 303 drives the movement of the extrusion rod 307, thereby achieving the purpose of easily handling different irregular sample heights.

[0037] Working principle: like Figure 1-7 As shown: In use: Place the irregular sample on the push stage 402, then rotate the threaded column 503 to drive the rubber pad 504 to squeeze the irregular sample, thereby achieving the purpose of initially fixing the irregular sample. Then, adjust the height of the adjusting plate 303 according to the height of the irregular sample. Subsequently, move the push stage 402 to drive the irregular sample to move, so that the top of the irregular sample contacts and squeezes the rubber sleeve 308. At this time, the squeezing rod 307 rotates. Finally, the irregular sample is squeezed and fixed by the downward squeezing force of the squeezing rod 307 and the elastic force of the rubber sleeve 308, which facilitates the subsequent operation of the spark ignition source 7 on the irregular sample. When testing irregular samples, the second bolt 404 can be unscrewed to ensure that the push stage 402 can slide normally. When testing columnar samples, the second bolt 404 can be screwed on directly to fix the push stage 402. Then, the columnar sample is pushed on the push stage 402, and the top of the columnar sample contacts and squeezes the rubber sleeve 308. At this time, the extrusion rod 307 rotates. Finally, the columnar sample is squeezed and fixed by the downward extrusion force of the extrusion rod 307 and the elasticity of the rubber sleeve 308, which facilitates the subsequent operation of the spark source 7 on the columnar sample. This reduces the number of testing steps for columnar samples and reduces the complexity of the operation. With one side of the irregular sample in contact with one end of the spark ignition source 7, the second threaded rod 802 is rotated to move the fixed column 301 according to the height of the irregular sample. The movement of the fixed column 301 moves the adjusting plate 303, which in turn moves the extrusion rod 307, thus achieving the purpose of easily handling different irregular sample heights.

It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
