Description

Technical Field

[0001] This utility model relates to the field of tooling technology, and in particular to a tooling device for fabricating glass slits in a vertical X-ray diffractometer. Background Technology

[0002] As a key precision instrument in materials science, chemistry, and physics research, X-ray diffractometers play an irreplaceable role in analyzing the crystal structure of materials. In the system configuration of a vertical X-ray diffractometer, the glass slit serves as the core sample calibration component, and its fabrication precision and flatness have a decisive impact on the accuracy of X-ray diffraction experimental results.

[0003] Under existing technologies, glass slits are typically fabricated manually or using simple fixing fixtures. Since glass slits are usually formed by gluing two glass plates together, several problems arise during actual operation. First, the lack of precise auxiliary methods for positioning the glass plates makes them prone to misalignment during installation, resulting in slit accuracy that fails to meet experimental requirements and the standards for high-precision scientific analysis. Second, there are technical bottlenecks in ensuring the flatness of the glass plate and the base, especially for circular glass plates. Due to their shape, achieving uniform contact during installation is difficult, making it hard to guarantee flatness. This flatness deviation alters the X-ray diffraction angle and intensity distribution, adversely affecting experimental results. Furthermore, traditional fixing methods are relatively simple and cannot simultaneously address the flatness requirements of the inner and outer surfaces of the glass plate. This can cause uneven local stress during fixing, reducing sample stability and further affecting the accuracy and repeatability of X-ray diffraction experiments. Therefore, this invention proposes a glass slit fabrication fixture for vertical X-ray diffractometers. Utility Model Content

[0004] The purpose of this invention is to address the problems in the existing glass slit fabrication technology, which uses manual installation or simple fixing fixtures, making it difficult to position the glass slide and ensure its easy displacement, making it difficult to guarantee the fit with the base and the flatness of the inner and outer ring surfaces, and resulting in poor sample stability due to the single fixing method, thus affecting the accuracy and repeatability of X-ray diffraction experiments. The invention proposes a glass slit fabrication fixture for vertical X-ray diffractometers.

[0005] The technical solution of this utility model is as follows: A tooling device for fabricating glass slits in a vertical X-ray diffractometer, comprising a limiting sleeve; a mounting block disposed at the bottom of the limiting sleeve, wherein a circular glass plate is mounted in the mounting block; a fixing block located below the mounting block, wherein a square glass plate is fixedly connected in the fixing block; a positioning mechanism for determining the relative position of the circular glass plate and the square glass plate; and a clamping assembly installed in the limiting sleeve for adjusting the flatness of the inner and outer ring surfaces of the circular and square glass plates.

[0006] Optionally, the limiting sleeve has a guide hole and an installation groove at its bottom, and the mounting block is installed in the installation groove.

[0007] Optionally, the mounting block has a first mounting hole, and the circular glass sheet is slidably connected in the first mounting hole.

[0008] Optionally, the fixing block has a second mounting hole, and the square glass sheet is mounted in the second mounting hole.

[0009] Optionally, the positioning mechanism includes two sets of placement slots opened at the bottom of the mounting block. The two sets of placement slots are symmetrically arranged on both sides of the circular glass plate and communicate with the first mounting hole. A positioning block is provided in the placement slot.

[0010] Optionally, the positioning block has at least two sets of threaded holes, the bottom of the fixing block has a groove corresponding to the threaded holes, and the top wall of the groove has a long adjustment hole.

[0011] Optionally, the clamping assembly includes a pressure column, a guide ring is fixedly connected to the outer ring of the pressure column, the guide ring is slidably connected in a guide hole, and a counterweight is fixedly connected to the top of the pressure column.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] This invention provides a precise installation and positioning method for circular and square glass plates by setting up an installation block, a fixing block, and a positioning mechanism. The first and second installation holes guide the installation of the circular and square glass plates, respectively. The positioning block in the positioning mechanism cooperates with the bolts to flexibly and precisely adjust and fix the relative position of the two glass plates, effectively avoiding the offset problem that is easy to occur in traditional manual installation, greatly improving the manufacturing precision of the glass slit, thereby ensuring the accuracy of X-ray diffraction experimental data.

[0014] Furthermore, the design of the clamping component can effectively ensure the flatness of the inner and outer ring surfaces of the glass slide. The pressure column slides smoothly in the guide hole through the guide ring. Relying on its own weight and the pressure increased by the counterweight, it acts evenly on the circular glass slide, thereby adjusting the flatness of the circular and square glass slide surfaces. This solves the problem of difficulty in ensuring the flatness of the glass slide and the base and the flatness of the inner and outer rings in the existing technology, improves the stability of the sample in the experiment, and ensures the reliability and repeatability of the X-ray diffraction experimental results.

[0015] In summary, this invention improves the manufacturing precision of the glass slit, ensures the flatness of the glass slide surface, enhances sample stability, and ensures the accuracy, reliability, and repeatability of X-ray diffraction experimental data. Attached Figure Description

[0031] Example

[0032] like Figure 1 and Figure 2 As shown, the present invention proposes a glass slit fabrication fixture for a vertical X-ray diffractometer, comprising a limiting sleeve 1, a guide hole 11 in the limiting sleeve 1, and an installation groove 12 at the bottom of the limiting sleeve 1. An installation block 2 is installed in the installation groove 12, and the opening of the installation groove 12 facilitates the installation of the installation block 2.

[0033] Furthermore, the aforementioned tooling device includes a mounting block 2 disposed at the bottom of the limiting sleeve 1, a circular glass plate 3 is mounted in the mounting block 2, and a first mounting hole 21 is provided in the mounting block 2. The circular glass plate 3 is slidably connected in the first mounting hole 21, and the first mounting hole 21 facilitates the placement and guidance of the circular glass plate 3.

[0034] Furthermore, the aforementioned tooling device also includes a fixing block 4 located below the mounting block 2. A square glass sheet 5 is fixedly connected to the fixing block 4. A second mounting hole 41 is provided in the fixing block 4. The square glass sheet 5 is installed in the second mounting hole 41. The bottom of the square glass sheet 5 is installed in the second mounting hole 41 through a support base. The spacing of the glass slits can be adjusted by adjusting the height of the square glass sheet 5.

[0035] For details, please refer to Figure 3 and Figure 4 The aforementioned tooling device also includes a positioning mechanism 6, which is used to determine the relative positions of the circular glass sheet 3 and the square glass sheet 5. The positioning mechanism 6 includes two sets of placement grooves 61 opened at the bottom of the mounting block 2. The two sets of placement grooves 61 are symmetrically arranged on both sides of the circular glass sheet 3 and communicate with the first mounting hole 21. Positioning blocks 62 are provided in the placement grooves 61, and at least two sets of threaded holes 63 are opened on the positioning blocks 62. A groove 64 is opened at the bottom of the fixing block 4 corresponding to the threaded holes 63, and a long adjustment hole 65 is opened on the top wall of the groove 64. By threading bolts into the threaded holes 63, after adjusting the position of the positioning block 62 to contact the circular glass sheet 3, the position of the positioning block 62 is determined. After tightening the bolts, the position of the positioning block 62 can be fixed, thereby fixing the relative positions of the circular glass sheet 3 and the square glass sheet 5.

[0036] Furthermore, such as Figure 1 As shown, the clamping assembly 7, installed in the limiting sleeve 1, is used to adjust the flatness of the inner and outer surfaces of the circular glass slide 3 and the square glass slide 5. The clamping assembly 7 includes a pressure column 71, with a guide ring 72 fixedly connected to its outer ring. The guide ring 72 is slidably connected in the guide hole 11. The pressure column 71 presses against the circular glass slide 3 by gravity and moves smoothly through the guide ring 72, thus maintaining uniform pressure. This ensures the flatness of the surfaces of the circular glass slide 3 and the square glass slide 5, enhances sample stability, and improves the reliability of experimental results. A counterweight 73 is fixedly connected to the top of the pressure column 71 to appropriately increase the pressure of the pressure column 71 on the circular glass slide 3.

[0037] In this embodiment, when using the glass slit manufacturing tooling device of this utility model, the mounting block 2 is first precisely installed in place using the mounting groove 12 at the bottom of the limiting sleeve 1. This structural design provides a stable initial installation foundation for the mounting block 2.

[0038] Subsequently, the fixing block 4, to which the square glass plate 5 is fixed, is placed below the mounting block 2. The square glass plate 5 is installed in the second mounting hole 41 via a support base. The spacing of the glass slits can be flexibly adjusted by adjusting the height of the square glass plate 5 in the second mounting hole 41 to meet different experimental needs. Next, the circular glass plate 3 is slidably embedded into the mounting block 2 along the first mounting hole 21. The first mounting hole 21 serves as a precise guide, ensuring the accuracy of the installation position of the circular glass plate 3.

[0039] The positioning mechanism 6 plays a crucial role in determining the relative positions of the circular glass plate 3 and the square glass plate 5. First, the positioning block 62 is placed in the placement groove 61 at the bottom of the mounting block 2. Since the placement groove 61 is symmetrically arranged on both sides of the circular glass plate 3 and communicates with the first mounting hole 21, it can initially position the positioning block 62. Then, the bolt is threaded into the threaded hole 63 of the positioning block 62. By pushing the positioning block 62 to make it in close contact with the circular glass plate 3, the position of the positioning block 62 in the placement groove 61 is adjusted according to the relative position required for the experiment. After the position is determined, the bolt is tightened to fix the positioning block 62 in the groove 64 of the fixing block 4. The long adjustment hole 65 provides space for adjusting the position of the positioning block 62, thereby accurately fixing the relative positions of the circular glass plate 3 and the square glass plate 5.

[0040] Finally, install the clamping assembly 7. Insert the clamping column 71 into the guide hole 11 of the limiting sleeve 1. Since the guide ring 72 of the outer ring of the clamping column 71 is slidably connected to the guide hole 11, it ensures that the clamping column 71 can move smoothly in the vertical direction. The clamping column 71, relying on its own weight and the pressure increased by the top counterweight 73, presses evenly on the circular glass plate 3. In this way, the flatness of the inner and outer ring surfaces of the circular glass plate 3 and the square glass plate 5 is adjusted, so that the two glass surfaces are tightly attached and remain flat, which enhances the stability of the sample during the experiment and effectively improves the accuracy and reliability of the X-ray diffraction experimental results.

[0041] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
