Description
Technical Field
[0001] The utility model relates to the technical field of X-ray diffraction testing, in particular to a block sample testing frame. Background Art
[0002] X-ray diffractometer (XRD) is one of the essential instruments for material analysis. It can characterize the phase structure, phase composition, grain size, crystallinity, grain orientation and microstructure of materials. During the test, the sample is placed in the sample slot of the instrument, and X-rays of a certain wavelength hit the surface of the sample. After diffraction of the atomic structure, the diffraction pattern after diffraction is collected by the signal detector to obtain information such as the composition of the material, the structure or morphology of the atoms or molecules inside the material, etc. For material-related majors, X-ray diffractometer is one of the necessary test instruments for experimental teaching and scientific research.
[0003] In the prior art, although the block sample test stand meets the test requirements to a certain extent, there are still some obvious disadvantages, such as: 1. Poor adaptability. Different block samples often have different sizes, shapes and weights, but the existing test stands often lack sufficient flexibility and adjustability, and it is difficult to adapt to the test requirements of various samples. 2. Risk of damage to the sample. In some cases, the surface of the block sample may be fragile or sensitive and easily damaged by external forces. When fixing the sample, the existing test stand may use a fixture that is too rigid or sharp, which increases the risk of scratching or indenting the sample surface. This not only affects the integrity of the sample, but may also interfere with subsequent testing and analysis. 3. Inconvenient operation. The design of some test stands is not user-friendly, making the operation process cumbersome and complicated. For example, adjusting the position and angle of the sample may require multiple removal and reinstallation of the fixture, which not only increases the operation time, but may also cause the sample position to shift due to improper operation. In addition, some test stands lack clear markings and instructions, making it easy for operators to make mistakes during operation.
[0004] In summary, it is particularly important to design a block sample test stand that is simple to operate, has no special requirements on the size and shape of the block sample, and can effectively ensure that the test plane and the clamping plane of the block sample are on the same horizontal line. Summary of the invention
[0005] The purpose of the utility model is to overcome the clamping problem of block samples in the above-mentioned background technology, and at the same time design a block sample test stand which is simple to operate, has good applicability and versatility, and can effectively ensure that the block sample test plane and the clamping plane are on the same horizontal line.
[0006] In order to achieve the above-mentioned purpose, the technical idea adopted by the utility model is: in solving the clamping problem of block samples in the prior art, in order to avoid the easy damage of block samples of different materials to the greatest extent, the utility model has greater flexibility and better adjustability for block materials of different sizes, weights and shapes. The block samples are fixed by gluing. Secondly, in order to effectively ensure that the test plane and the clamping plane of the block sample are on the same horizontal line, the utility model adopts screw rods for precise adjustment and fixation. Finally, the sample slot and the clamping frame should be stably fixed to ensure that the sample will not shake and affect the experimental results during the diffraction process.
[0007] Based on the above technical ideas, the technical solution adopted by the utility model is:
[0008] A block sample testing frame comprises a clamping frame and a sample slot arranged on the clamping frame. A positioning sleeve is vertically penetrated through the clamping frame, and the sample slot and the positioning sleeve are detachably connected.
[0009] The positioning sleeve has a height adjuster and a leveler at the bottom; the height adjuster is used to adjust the height of the sample slot; the leveler is used to adjust the horizontality of the sample slot; the sample slot is used to place block samples.
[0010] To further limit the above technical solution, the height adjuster includes a height adjustment screw, which passes through the height adjustment screw hole at the bottom of the positioning sleeve and abuts against the positioning groove at the bottom of the sample slot to adjust the height of the sample slot.
[0011] To further define the above technical solution, the leveler includes a plurality of leveling screws, which pass through the leveling screw holes at the bottom of the positioning sleeve and abut against the bottom of the sample slot to adjust the horizontality of the sample slot.
[0012] A further limitation of the above technical solution is that the positioning sleeve has an upper half of a wall thereof provided with a locking groove for locking the sample slot; a height adjustment screw hole and a plurality of leveling screw holes are provided at the bottom thereof.
[0013] Further limiting the above technical solution, the sample tank has a positioning groove at the bottom for cooperating with the height adjuster, and the outer surface is provided with engaging stripes perpendicular to the bottom of the sample tank for engaging with the positioning sleeve. Preferably, the sample tank is made of quartz material.
[0014] As a further limitation of the above technical solution, a thread is provided inside the positioning groove for cooperating with the height adjuster.
[0015] A further limitation of the above technical solution also includes a glass cover plate placed on the upper surface of the clamping frame so that the upper surface of the clamping frame and the upper surface of the sample groove are kept flush.
[0016] A further limitation of the above technical solution is that it also includes an adhesive layer, which is arranged at the bottom of the sample slot and is used to adhere the block sample. Preferably, the adhesive layer is made of plasticine or double-sided tape.
[0017] To further limit the above technical solution, the clamping frame includes a clamping frame plate 1, a clamping frame plate 2 and a clamping frame plate 3, which form a Z-shaped structure. Preferably, the clamping frame is made of aluminum alloy.
[0018] Compared with the prior art, the beneficial effects of the utility model are:
[0019] (1) Compact and stable structure: The entire test frame is reasonably designed, compact and occupies little space. The clamping frame adopts a Z-shaped metal structure, which can provide stable support for the sample slot while meeting the limit requirements required for the test sample. At the same time, the precise engagement of the positioning sleeve, sample slot and screw further improves the stability of the new model.
[0020] (2) Strong adaptability: The design of the adhesive layer and sample slot can adapt to block samples of different sizes and shapes. At the same time, since the block samples are fixed by adhesive, the material requirements for the block samples are lowered, reducing the possibility of surface damage to the material due to clamping.
[0021] (3) Precise positioning: The position of the sample in the X-ray diffractometer can be precisely controlled by adjusting the positioning sleeve, height adjuster and glass cover. The cooperation of the glass cover and leveler can effectively ensure that the test plane of the block sample and the clamping plane are on the same horizontal plane, thereby improving the accuracy of the diffraction data.
[0022] (3) Easy operation: The design of this new model takes into account the convenience of operation. The sample rack has a simple structure. The tester only needs to assemble it simply and stick the sample in the sample slot to perform the test operation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0031] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the contents of the present invention, those skilled in the art may make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to this application. Example 1
[0032] This embodiment provides a block sample test rack, such as Figure 1 As shown, it includes a clamping frame 1 and a sample slot 2 arranged on the clamping frame 1, characterized in that a positioning sleeve 3 is vertically penetrated on the clamping frame 1, and the sample slot 2 is detachably connected to the positioning sleeve. The positioning sleeve 3 has a height adjuster and a leveler at the bottom; wherein the height adjuster is used to adjust the height of the sample slot 2; and the leveler is used to adjust the horizontality of the sample slot 2.
[0033] Combination Figure 1 , Figure 2 and Figure 5 In the embodiment of the utility model, the height adjuster includes a height adjustment screw 4, which passes through the height adjustment screw hole 32 at the bottom of the positioning sleeve 3 and abuts against the positioning groove 22 at the bottom of the sample tank 2, so as to adjust the height of the sample tank 2. The leveler includes a plurality of leveling screws 5, which pass through the leveling screw holes 33 at the bottom of the positioning sleeve 3 and abut against the bottom of the sample tank 2, so as to adjust the horizontality of the sample tank 2.
[0034] The upper half of the positioning sleeve 3 is provided with a clamping groove 31 for clamping the sample slot 2. A height adjustment screw hole 32 and a plurality of leveling screw holes 33 are provided at the bottom.
[0035] The sample tank 2 has a positioning groove 22 at the bottom for cooperating with the height adjustment screw 4 to prevent the height adjustment screw 4 from slipping, and a snap-fitting stripe 21 perpendicular to the bottom of the sample tank 2 is provided on the outer surface for snap-fitting with the positioning sleeve 3 .
[0036] In this embodiment, reference Figure 2 and Figure 5 The sample slot 2 is placed into the positioning sleeve 3 with the upper surface of the vertical clamping frame 1, and the engaging stripes 21 on its outer circumferential surface are vertically engaged with the engaging grooves 31 of the upper half of the positioning sleeve 3, so that the sample slot 2 will not rotate in the horizontal direction. In the vertical direction, the sample slot 2 can slide within a certain limit within the range of the engaging grooves 31 of the positioning sleeve 3 along with the engaging stripes 21.
[0037] A positioning groove 22 is provided at the bottom of the sample tank 2 to prevent the height adjustment screw 4 from slipping. The height adjustment screw 4 passes through the height adjustment screw hole 32 at the bottom of the positioning sleeve 3 and abuts against the positioning groove 22 at the bottom of the sample tank 2, thereby further accurately adjusting the vertical height of the sample tank 2. Since the height adjustment screw 4 is engaged with the height adjustment screw hole 32 at the bottom of the positioning sleeve 3, the height adjustment screw 4 can not only adjust the height of the sample tank 2, but also provide a certain degree of support to the sample tank 2. This effectively ensures that the block sample test plane and the clamping plane are on the same horizontal plane.
[0038] refer to Figure 6 In an embodiment of the utility model, a glass cover plate 7 is further included, which is placed on the upper surface of the clamping frame 1 so that the upper surface of the clamping frame 1 and the upper surface of the sample groove 2 remain flush.
[0039] In this embodiment, the glass cover plate 7 is first placed on the upper surface of the clamping frame 1, and the upper surface of the clamping frame 1 and the upper surface of the sample tank 2 are kept flush with each other through the cooperation of the leveler, that is, multiple leveling screws 5. After adjusting the level of the sample tank 2, the glass cover plate 7 is removed to avoid the presence of the glass cover plate 7 affecting the transmission of X-rays.
[0040] refer to Figure 4 and Figure 6 In the embodiment of the utility model, an adhesive layer 6 is further included, which is arranged at the bottom of the sample slot 2 and is used to adhere the block sample. Preferably, the adhesive layer 6 is made of plasticine, double-sided tape, transparent tape, grease or glue with low background diffraction.
[0041] The sample needs to maintain a stable position and posture during the test to avoid test errors caused by movement or tilt. The adhesive layer 6, such as double-sided tape, plasticine, etc., can adhere tightly to the sample and provide sufficient fixing force to ensure that the sample does not move during the diffraction process.
[0042] At the same time, the adhesive layer 6 can effectively fix the sample on the sample stage. The sample stage is one of the key components of the X-ray diffractometer and is responsible for supporting and positioning the sample. By using the adhesive layer 6, the sample can be firmly attached to the sample stage to ensure that the relative position of the sample and the X-ray source remains unchanged, thereby obtaining accurate diffraction data.
[0043] Combination Figure 1 In an embodiment of the utility model, the clamping frame 1 includes a clamping frame plate 11, a clamping frame plate 2 12 and a clamping frame plate 3 13, which form a Z-shaped structure. Preferably, the clamping frame 1 is made of aluminum alloy material, and the sample slot 2 is made of quartz material.
[0044] In practical applications, the Z-shaped structure has excellent stability and support. This structure can effectively support and fix the sample, ensuring that the sample maintains a stable position and posture during the test, thereby avoiding test errors caused by sample movement or tilt.
[0045] Furthermore, the clamping frame 1 can also be made of acrylic material, stainless steel, quartz or carbon fiber composite material. Quartz material has outstanding advantages in X-ray diffraction, such as high stability, low absorption, low background noise and easy processing, which helps to improve the accuracy and reliability of diffraction experiments, thereby better analyzing the crystal structure and properties of samples.
[0046] The quartz material of the sample tank 2 can also be replaced by graphite or silicon according to various factors such as specific experimental requirements, sample properties, and equipment conditions.
[0047] In the schematic diagram provided in the utility model Figure 6 In order to make it easier to see the structure, the glass cover 7 and the upper surfaces of the clamping frame 1 as well as the positioning sleeve 3 and the sample slot 2 are not in contact. In actual operation, the function of the glass cover 7 is to make the upper surface of the clamping frame 1 flush with the upper surface of the sample slot 2 and to keep the sample slot 2 level. Therefore, the glass cover 7 needs to be in contact with the upper surface of the clamping frame 1 to further level the sample slot 2.
[0048] refer to Figure 6 The sample slot 2 is higher than the sleeve 3, so as to avoid interfering with the diffraction result of the sample when the X-ray is irradiated on the sleeve 3. Example 2
[0049] refer to Figure 3 In order to further increase the stability of the sample slot 2, a thread can be provided inside the positioning groove 22, and the thread is engaged with the height adjustment screw 4. When in use, refer to Figure 5 The height adjustment screw rod 4 passes through the height adjustment screw hole 32 at the bottom of the positioning sleeve 3 and is screwed into the positioning groove 22 at the bottom of the sample tank 2. The rest of the parts are the same as those in the first embodiment. Example 3
[0050] The specific use process of the block sample test stand provided by the utility model is:
[0051] First, fix the block sample in the sample slot 2 through the adhesive layer 6 , and vertically place the sample slot 2 into the positioning sleeve 3 , so that the snap-fitting stripes 21 on the outer peripheral surface of the sample slot 2 snap into the snap-fitting grooves 31 on the wall of the positioning sleeve 3 .
[0052] Second, pass the height adjustment screw 4 through the bottom of the positioning sleeve 3 so that the height adjustment screw 4 abuts against the positioning groove 22 at the bottom of the sample tank 2, and roughly adjust the height adjustment screw 4 so that the upper surface of the sample tank 2 is roughly flush with the upper surface of the clamping frame.
[0053] Third, place the glass cover plate 7 on the upper surface of the clamping frame 1, further adjust the height adjustment screw 4 to make the upper surface of the sample slot 2 and the glass cover plate 7 fit together, pass multiple leveling screws 5 through the screw holes at the bottom of the positioning sleeve 3, adjust multiple leveling screws 5 to make the upper surface of the clamping frame 1 and the glass cover plate 7 completely fit together, thereby ensuring that the upper surface of the sample slot 2 and the upper surface of the clamping frame 1 are on the same level.
[0054] Fourth, remove the glass cover 7.
[0055] Fifth, conduct X-ray diffraction test.
[0056] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementation schemes, so that those skilled in the art can understand and apply the present invention. It cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, some simple deductions or substitutions can be made without going through creative work without departing from the concept of the present invention. Therefore, simple improvements made to the present invention by those skilled in the art based on the disclosure of the present invention should be within the scope of protection of the present invention.
