Description

Technical Field

[0001] This utility model belongs to the field of special coatings research technology, and in particular relates to an apparatus for research on functional special coatings. Background Technology

[0002] In modern industry and scientific research, the application of functional specialty coatings is becoming increasingly widespread, and their performance directly affects the quality, safety, and service life of numerous products. For example, in the aerospace field, specialty coatings need to possess excellent impact resistance to protect the surface of aircraft from impacts by micrometeoroids and debris; in automobile manufacturing, impact-resistant coatings enhance the protective capabilities of the vehicle body and reduce damage during collisions. Therefore, accurate research and evaluation of the performance of specialty coatings are crucial.

[0003] Currently, various testing devices exist for the impact resistance of specialty coatings. Common methods include simple manual drop hammer devices, where a hammer is manually operated to impact the sample; and more complex electric impact structures with a degree of automation. However, these existing technologies suffer from numerous drawbacks and problems. Manual drop hammer devices rely entirely on manual operation, making it difficult to ensure consistent hammer height and speed with each impact, leading to significant deviations in test results and failing to accurately reflect the coating's true impact resistance. The rigor and accuracy of the test cannot be guaranteed. While some electric impact structures offer automation, their structural design is flawed, allowing the hammer to wobble or shift during impact, similarly affecting test accuracy. Furthermore, most existing devices lack robust sample fixation and displacement adjustment mechanisms, making it difficult to conduct comprehensive impact tests on different parts of the sample and obtain impact resistance data for each component. Moreover, the determination of test results relies solely on the operator's subjective experience, lacking objective and standardized criteria. This significantly reduces the accuracy and reliability of the test results, severely hindering the further development of specialty coatings research. Utility Model Content

[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0025] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly.

In this specification, illustrative expressions of the above terms do not necessarily refer to the same solution or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more solutions or examples.

[0027] like Figures 1-4 As shown in the figure, an embodiment of this utility model proposes an apparatus for research on functional specialty coatings, which includes an operating table 1, a comparison area, a drop hammer 8 impact structure, and a movable sample plate 9. A comparison area is provided on one side of the operating table 1 surface 2, allowing operators to quickly and easily compare the sample to be tested with a standard sample 3 after completing the impact test. A drop hammer 8 impact structure is provided on the other side of the operating table 2, and the movable sample plate 9 is located at the bottom of the drop hammer 8 impact structure.

[0028] This equipment is used to test the impact resistance of coatings and to classify the samples based on their performance, which can further advance the research on impact-resistant coatings.

[0029] The bottom of the operating table 1 is a cabinet-shaped storage area with ample space for storing various experimental tools, spare samples, and related test reports, greatly improving the utilization of the experimental space. The operating table 1 is mounted on top of the cabinet-shaped storage area. A vertical guide rail 6 is installed on the top of the operating table 1, with guide grooves on opposite sides of the guide rail 6. Slider blocks 7 are fixedly installed on both sides of the drop hammer 8. The combined width of the slider 7 and the drop hammer 8 is greater than the distance between the guide rails 6. This design ensures a stable connection between the drop hammer 8 and the guide rails 6, preventing easy shaking or displacement. The slider 7 is located inside the guide rail 6. A locking block, which is elongated, is located on the top of the guide rail 6 and extends through the guide rail 6 into the guide groove inside the guide rail 6. When using the drop hammer 8 impact structure, the slider 7 is moved to the top of the guide groove, and the locking piece is fixed to the bottom of the slider 7 through the guide rail 6. This supports the slider 7 at the top of the guide groove. When an impact is needed, the locking piece is removed, and the drop hammer 8 will descend vertically under the action of gravity. The presence of the guide rail 6 can restrict the position of the drop hammer 8, allowing it to fall to a fixed position. Since the position of the locking piece is fixed, it can be ensured that the drop hammer 8 falls to a fixed height each time, ensuring that the impact force of the drop hammer 8 on the sample is consistent in each impact test, thereby ensuring the rigor and accuracy of the test.

[0030] The impact structure of the drop hammer 8 is equipped with a safety guard 13 on the outside, and the guard has a push-pull opening on one side, which can increase the safety of the impact test.

[0031] Between the guide rails 6 and below the drop hammer 8, a sample plate 9 is placed. The upper surface of the sample plate 9 has a groove in the middle that matches the sample size. During the impact test, the sample can be placed in the groove inside the sample plate 9. The groove matches the sample size and can accurately fix the sample position, preventing the sample from shifting during the impact. The sample plate 9 can ensure that the sample position is fixed and the impact position of the drop hammer 8 is fixed.

[0032] The center and sides of the sample exhibit different behaviors when subjected to impact, both reflecting the sample's quality. Therefore, a displacement device is installed at the bottom of the sample plate 9 to move it to a specific position for impact testing. A limiting block is fixedly installed at the bottom of the sample plate 9, and a limiting groove corresponding to the limiting block is provided on the surface of the platform 2 at the bottom of the sample plate 9. A threaded rod 11 penetrates the bottom of the sample plate 9, and a mounting plate 12 is provided on one side of the sample plate 9, with one end of the threaded rod 11 movably connected to the surface of the mounting plate 12. A stepper motor 10 is fixedly installed on the other side of the sample plate 9, and the output end of the stepper motor 10 is fixedly connected to the other end of the threaded rod 11. The length of the threaded rod 11 is 1.5 times the length of the sample plate 9. When the output end of the stepper motor 10 rotates, it drives the threaded rod 11 to rotate, and the sample plate 9 can only move along the direction of the threaded rod 11 under the restriction of the limiting block and the limiting groove. The stepper motor 10 can rotate a limited number of times each time, thus moving the sample plate 9 a corresponding distance. In the initial position, the falling hammer 8 impacts the side of the sample on the sample plate 9. The stepper motor 10 rotates a corresponding number of revolutions, moving the center of the sample to the bottom of the falling hammer 8. The falling hammer 8 then lands on the center of the sample, achieving impact on both the side and center of the sample. The displacement device, using a stepper motor 10 and a threaded rod 11 in conjunction with a limiting block and a limiting groove, can precisely control the moving distance of the sample plate 9, facilitating impact testing at different positions of the sample and comprehensively evaluating the sample's impact resistance.

[0033] Before testing, multiple sets of standard-grade samples were subjected to drop-weight 8 impact tests inside the drop-weight 8 impact structure. After the test, the average performance sample from the control group was taken as standard sample 3. Standard sample 3 was placed in the standard comparison area on one side of the operating table 1. A groove was opened on the side of the table surface 2 away from the drop-weight 8 impact structure, and the bottom of the groove was marked with grade markings 4. The selected standard sample 3 was placed in the corresponding position according to the grade markings 4. A protective cover 5 was movably installed on the top of the groove. After the sample was placed, the protective cover 5 was installed. The groove, together with the grade markings 4, facilitated the classification, placement, and management of standard sample 3. The protective cover 5 effectively protected the standard sample 3, preventing it from being interfered with by external environmental factors and ensuring the accuracy of the comparison.

[0034] After the sample to be tested completes the impact test in the impact testing equipment area, the sample is compared with the standard sample 3 of the standard comparison sample to achieve the grade classification.

[0035] This invention utilizes the coordinated operation of components such as the operating platform 1 and the impact structure of the falling hammer 8 to achieve state changes. When testing the impact resistance of coatings, the impact structure of the falling hammer 8 operates precisely at all times, and the guide rail 6 provides a stable limiting effect on the falling hammer 8 during the impact process, ensuring the rigor and accuracy of the impact test while facilitating operation and control. The ingenious structural design and displacement control method enable impact testing at different positions of the sample, improving the comprehensiveness and scientific rigor of the test. The inclusion of a standard comparison area facilitates the judgment and comparison of test results, making the test more rigorous, improving the efficiency of determining the grade of the tested product, and further advancing the research of special coatings.
