Description

Technical Field

[0001] This utility model relates to the field of copper tube processing, and in particular to a device for rapid positioning of the excitation point of cylindrical samples in a direct-reading spectrometer. Background Technology

[0002] Direct-reading spectrometers, also known as spark emission spectrometers (OES), are rapid quantitative analytical instruments for analyzing the chemical composition of ferrous and non-ferrous metals and are one of the effective means of controlling product quality. The working principle of a direct-reading spectrometer is to use the high temperature of an electric spark to directly vaporize each element in the sample test area (excitation point area) from the solid state and excite it to emit the characteristic spectral lines of each element. The intensity of the emission spectral line of each element is proportional to the content of that element in the sample.

[0003] When using a direct-reading spectrometer to analyze the composition of metal samples, the test point / excitation point of the metal sample must be aligned with the excitation hole on the excitation stage beforehand, with the test surface / excitation point facing downwards. The test point area should block the excitation hole and be located within the excitation hole area before starting the test. During the test, the sample test surface must completely cover the excitation hole to prevent air leakage. The problem that this invention needs to solve is as follows:

[0004] 1. Without a positioning device, it is necessary to visually align the sample test point with the excitation hole so that the required test point of the sample is located in the center of the excitation hole area and pressed on the excitation hole to prevent air leakage. This visual alignment method is time-consuming and has the risk of alignment deviation.

[0005] 2. When testing multiple regions on the same sample surface, the method of visual alignment is insufficient to fully utilize the effective area of ​​the sample test surface. This may result in overlapping excitation points or adjacent excitation points being too far apart, wasting the effective area between adjacent test points. (OES is a destructive testing method; secondary testing of the same excitation point area is not recommended.)

[0006] 3. Existing positioning devices are only suitable for samples with a single outer diameter. When the outer diameter of the sample changes, a positioning device of the corresponding size needs to be replaced. If there are many samples with different outer diameters, the positioning device needs to be replaced frequently. Utility Model Content

[0007] The main purpose of this invention is to provide a rapid excitation point positioning device for cylindrical samples in a direct-reading spectrometer that can adapt to samples with different outer diameters and can easily adjust the relative position of the test sample and the excitation hole, thereby improving testing efficiency.

[0008] This invention proposes a rapid excitation point positioning device for cylindrical samples in a direct-reading spectrometer, comprising an excitation stage base, a positioning groove plate, and bolts;

[0009] The excitation stage base is provided with an excitation hole that penetrates the excitation stage base. A base connecting groove is provided at the bottom of the excitation stage base corresponding to the position of the excitation hole. The excitation stage base is connected to the direct-reading spectrometer through the base connecting groove. The excitation hole corresponds to the excitation point of the direct-reading spectrometer.

[0010] The top of the excitation platform base is provided with at least two base connection holes, and the top of the positioning slot plate is provided with a slot plate connection slot corresponding to the base connection holes. The base connection holes and the slot plate connection slot are connected by bolts, so that the positioning slot plate can be connected and installed on the excitation platform base.

[0011] A limiting groove is provided on the front side of the positioning groove plate, and the test sample is limited and positioned in front of the limiting groove. By adjusting the relative position of the base connecting hole and the groove plate connecting groove, the relative position of the positioning groove plate and the excitation stage base can be adjusted, thereby adjusting the relative position of the test sample and the excitation point.

[0012] Preferably, the limiting groove is a V-shaped groove.

[0013] Preferably, a scale is provided on the top of the excitation stage base, which allows for quick positioning of the test sample center.

[0014] The beneficial effects of this invention's rapid excitation point positioning device for cylindrical samples in a direct-reading spectrometer are as follows:

[0015] 1. By rotating the positioning slot plate horizontally by 180°, the other end of the V-shaped limiting slot, i.e., the flat end, can also be used for the rapid positioning of some square samples. It is not limited to cylindrical samples, thus meeting the needs of more test samples at the same time.

[0016] 2. The sliding design of the V-shaped positioning groove eliminates the need to replace the positioning groove plate and scale multiple times during testing due to different sample sizes. This makes fixing the positioning groove plate quicker and more convenient, improving testing efficiency and the accuracy of test results. Attached Figure Description

[0023] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0024] Reference Figures 1 to 4 An embodiment of the present invention for a rapid excitation point positioning device for cylindrical samples in a direct-reading spectrometer is presented:

[0025] A device for rapid excitation point positioning of cylindrical samples in a direct-reading spectrometer includes an excitation stage base 1, a positioning groove plate 2, and bolts 3.

[0026] An excitation hole 11 is provided on the excitation stage base 1, penetrating the excitation stage base 1. A base connecting groove 12 is provided on the bottom of the excitation stage base 1 at the position corresponding to the excitation hole 11. The excitation stage base 1 is connected to the direct-reading spectrometer through the base connecting groove 12. The excitation hole 11 corresponds to the excitation point of the direct-reading spectrometer. Two base connecting holes 13 are provided on the top of the excitation stage base 1.

[0027] The top of the positioning slot plate 2 is provided with a slot plate connecting slot 21 corresponding to the base connecting hole 13. The base connecting hole 13 and the slot plate connecting slot 21 are connected by bolts 3, so that the positioning slot plate 2 can be connected and set on the excitation stage base 1. A limiting slot 22 is provided on the front side of the positioning slot plate 2. The limiting slot 22 is a V-shaped slot with an opening of 90°. The test sample 4 is limited and set on the front side of the limiting slot 22. By adjusting the relative position of the base connecting hole 13 and the slot plate connecting slot 21, the relative position of the positioning slot plate 2 and the excitation stage base 1 can be adjusted.

[0028] A scale 14 is provided on the rear side of the top of the excitation stage base 1. The scale lines of the scale 14 correspond to R30, R35, R40 and R45 respectively. When the rear side of the positioning slot plate 2 stops at the corresponding scale grid, it corresponds to the radius of the circular test sample 4 at that time, so that the center of the test sample 4 can be quickly located by means of the scale 14.

[0029] In use, if the radius of the test sample 4 is 35 mm, adjust the rear side of the positioning slot plate 2 to the corresponding R35 graduation line on the scale 14, and lock the positioning slot plate 2 onto the excitation stage base 1 using bolts 3. At this point, when the test sample 4 is placed on the excitation stage base 1 and locked into the limiting groove 22, its center corresponds precisely to the excitation point of the direct-reading spectrometer. By adjusting the relative position of the positioning slot plate 2 and the excitation stage base 1, continuous circumferential or unidirectional testing of the sample can be achieved.

Any equivalent structural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
