Abstract
Description
Technical Field
[0001] This application relates to the field of vibration reduction technology, and in particular to a vibration reduction performance testing fixture. Background Technology
[0002] Vibration damping performance testing is a systematic method to evaluate the energy dissipation capacity and stability of components under dynamic loads. Its core lies in quantifying damping characteristics, fatigue life, and environmental adaptability. Specifically, during the vibration damping performance testing of the component under test, it must be fixed to the test bench of the vibration damping performance testing equipment by means of binding or adhesive, simulating the component's installation state in actual applications, in order to detect the vibration damping performance of the component under test.
[0003] However, when the test component is fixed to the vibration reduction performance testing equipment in the above manner, as the vibration continues and the amplitude of the vibration increases, the test component may shift, slide, or jump on the test bench of the vibration performance testing equipment, resulting in distortion of the vibration waveform, which cannot truly reflect the vibration reduction performance, thereby reducing the accuracy of the vibration reduction performance test results of the test component. Based on this, this application proposes a vibration reduction performance testing fixture. Utility Model Content

The first positioning shaft extends into the positioning hole, the second positioning shaft passes through the positioning through hole, and the positioning cap is placed on the top end of the second positioning shaft and extends into the positioning through hole.
[0016] Specifically, when the lower surface of the second mounting base abuts against the top surface of the first positioning shaft, the top of the component to be tested abuts against the inner top surface of the limiting groove.
[0017] Optionally, there are multiple positioning holes, and one positioning hole is provided in the middle between every two adjacent mounting slots on the first mounting base;

Detailed Implementation
[0034] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.
[0035] refer to Figures 1 to 5 This application provides a vibration reduction performance testing fixture, including: a first mounting base 100 and a second mounting base 200 corresponding to the first mounting base 100; in actual use, the second mounting base 200 is located above the first mounting base 100.
[0036] The first mounting base 100 has a mounting groove 101 for mounting the component 300 to be tested, and it is mounted on the test bench 400 of the vibration damping performance testing equipment. The shape of the mounting groove 101 depends on the shape of the component 300 to be tested, and the mounting groove 101 matches the lower section of the component 300 to be tested, thereby fixing the lower section of the component 300 to be installed within it. Furthermore, the vibration damping performance testing equipment can be a vibration damper performance indicator testing machine, an electric vehicle vibration damping fatigue performance testing machine, etc., depending on the actual situation, and this application does not specifically limit it. The first mounting base 100 can be fixedly connected to the test bench 400 of the vibration damping performance testing equipment by bolts or other means. The component 300 to be tested can also be fixed in the mounting groove 101 by screws or other means, which can be set according to the actual situation, and this application does not specifically limit it.
[0037] In this design, the top of the component under test 300, installed in the mounting groove 101, is higher than the top surface of the mounting groove 101 by a predetermined height. The specific value of this predetermined height depends on the depth of the mounting groove 101 and the height of the component under test 300, but this application does not specify a particular value for it. During the vibration damping performance test of the component under test 300, to ensure its stability, not only the lower section of the component under test 300 needs to be fixed, but its upper section also needs to be fixed. The reason why the top of the component under test 300 installed in the mounting groove 101 is higher than the top surface of the mounting groove 101 is to fix the upper section of the component under test 300 through the second mounting base 101, thereby ensuring the overall stability of the component under test 300.
[0038] The second mounting base 200 has a limiting groove 201 corresponding to the mounting groove 101 and adapted to the upper section of the component under test 300. It is connected to the first mounting base 100 via a positioning pin 500 and is used to limit the upper section of the component under test 300. The positioning pin 500 fixes the first mounting base 100 and the second mounting base 200 together, thereby fixing the upper and lower sections of the component under test 300 respectively through the mounting groove 101 on the first mounting base 100 and the limiting groove 201 on the second mounting base 200. This improves the stability of the component under test 300 during vibration performance testing and ensures the accuracy of the test results.
[0039] The vibration damping performance testing fixture provided in this application installs the component to be tested 300 in the mounting groove 101 opened on the first mounting base 100. Since the second mounting base 200 has a limiting groove 201 that corresponds to the mounting groove 101 and is adapted to the upper section of the component to be tested 300, the second mounting base 200 and the first mounting base 100 are fixedly connected together by the positioning pin 500. This achieves the fixing of the mounting groove 101 and the limiting groove 201 to the lower and upper sections of the component to be tested 300. Then, the first mounting base 100 is fixedly connected to the test bench 400 of the vibration damping performance testing equipment, thereby ensuring the stability of the component to be tested 300 during the vibration generated by the vibration damping performance testing equipment. Compared to existing methods such as binding or gluing, this application, through the design of the first mounting base 100, the second mounting base 200, the mounting groove 101, and the limiting groove 201, can effectively fix the component under test 300 on the vibration reduction performance testing equipment, thereby avoiding the component under test 300 from shifting, sliding, or jumping on the test bench 400 of the vibration performance testing equipment, and thus improving the accuracy of the vibration reduction performance test results of the component under test 300.
[0040] In some embodiments, reference Figures 1 to 5In this application, both the first mounting base 100 and the second mounting base 200 are square. The square structure is superior to the circular structure in terms of bending and torsional stiffness due to its right-angled edges and planar characteristics. It is also convenient to open through holes for the positioning pin 500 to pass through and fixing holes for fixing the first mounting base 100 to the test bench 400 of the vibration reduction performance testing equipment.
[0041] In addition, there are multiple mounting slots 101, which are opened near the four right angles of the first mounting base 100; that is, there are four mounting slots 101 and they correspond one-to-one with the four right angles of the first mounting base 100. This not only enables the simultaneous testing of the vibration reduction performance of multiple test components 300, but also ensures the uniformity of the distribution of multiple test components 300 on the first mounting base 100, so as to ensure that the force on multiple test components 300 is uniform during the vibration reduction process.
[0042] Accordingly, there are multiple limiting grooves 201, and each limiting groove 201 corresponds to a multiple mounting groove 101. This ensures that while the lower section of each component 300 to be tested is fixed, the upper section is also fixed in the limiting groove 201, thereby improving the overall stability of each component 300 to be tested.
[0043] In some embodiments, reference Figure 1 and Figure 2 In this application, the first mounting base 100 is provided with a positioning hole 102, and the second mounting base 200 is provided with a positioning through hole 202 corresponding to the positioning hole 102; wherein, the positioning hole 102 and the positioning through hole 202 corresponding to the positioning hole 102 are both for installing a positioning pin 500, so as to fix the first mounting base 100 and the second mounting base 200 together by means of the positioning pin 500.
[0044] In addition, the positioning pin 500 includes an integrally formed first positioning shaft 501, a second positioning shaft 502, and a positioning cap 503; specifically, the first positioning shaft 501 is adapted to the positioning hole 102, and the diameter of the second positioning shaft 502 is smaller than the diameter of the first positioning shaft 501 and the positioning through hole 202, while the diameter of the first positioning shaft 501 is larger than the diameter of the positioning through hole 202 (wherein, this ensures that the top surface of the first positioning shaft 501 and the bottom end of the second positioning shaft 502 form a platform that can support the lower surface of the second mounting base 200). The positioning cap 503 is adapted to the positioning through hole 202. The first positioning shaft 501 extends into the positioning hole 102, and the second positioning shaft 502 passes through the positioning through hole 202. The positioning cap 503 covers the top of the second positioning shaft 502 and extends into the positioning through hole 202. The first positioning shaft 501 and the positioning hole 102 are interference-fitted, as are the positioning cap 503 and the positioning through hole 202, thus ensuring the stability of the connection between the first positioning shaft 501 and the positioning hole 102, and the stability of the connection between the positioning cap 503 and the positioning through hole 202. Furthermore, for the stability of the connection between the first mounting base 100 and the second mounting base 200, the diameter of the second positioning shaft 500 is adapted to the inner diameter of the positioning cap 503.
[0045] When the lower surface of the second mounting base 200 abuts against the top surface of the first positioning shaft 501, the top of the component to be tested 300 abuts against the inner top surface of the limiting groove 201. This ensures that the second mounting base 200 and the limiting groove 201 thereon only serve to fix the upper part of the component to be tested 300. During the vibration of the vibration damping performance testing equipment, the top of the component to be tested 300 will not be subjected to pressure from the second mounting base 200. This ensures that the component to be tested 300 is only subjected to the vibration force from the vibration damping performance testing equipment, thereby ensuring the accuracy of the vibration damping performance test results of the component to be tested 300.
[0046] In the above embodiment, when the first mounting base 100 and the second mounting base 200 are fixed together by the positioning pin 500, the end of the first positioning shaft 501 away from the second positioning shaft 502 is first inserted into the positioning hole 102. Then, the side of the second mounting base 200 with the limiting groove 201 is facing down, and the end of the second positioning shaft 502 away from the first positioning shaft 501 passes through the positioning through hole 202 on the second mounting base 200 until the lower surface of the second mounting base 200 abuts against the upper surface of the first positioning shaft 501. At this time, the positioning cap 503 is placed on the second positioning shaft 502 extending outward. One end of the positioning through hole 202 is embedded in the positioning through hole 202 (wherein, in order to prevent the second positioning shaft 502 from being able to extend into the positioning through hole 202, the length of the second positioning shaft 502 extending out of the positioning through hole 202 is less than the height of the positioning cap 503), thereby fixing the first mounting base 100 and the second mounting base 200 together, and fixing the lower and upper sections of the test element 300 respectively through the mounting groove 101 on the first mounting base 100 and the limiting groove 201 on the second mounting base 200, thereby improving the stability of the test element during the vibration performance test.
[0047] In some embodiments, reference Figure 1 and Figure 2 In this application, there are multiple positioning holes 102. A positioning hole 102 is provided in the middle between every two adjacent mounting slots 101 on the first mounting base 100; that is, there are four positioning holes 102 and the four positioning holes 102 are evenly provided on the first mounting base 100.
[0048] Accordingly, there are multiple positioning through holes 202 and positioning pins 500, each corresponding to a one-to-one positioning hole 102.
[0049] In the above embodiments, by uniformly opening a plurality of positioning holes 102 on the first mounting base 100, and opening a plurality of positioning through holes 202 corresponding one-to-one with the plurality of positioning holes 102 on the second mounting base 200, as well as setting a plurality of positioning pins 500, the stability of the connection between the first mounting base 100 and the second mounting base 200 is ensured, thereby improving the stability of the component under test 300 being fixed by the first mounting base 100 and the second mounting base 200.
[0050] In some embodiments, reference Figure 5 In this application, the first mounting base 100 is connected to the test bench 400 of the vibration reduction performance testing equipment by fastening bolts 600, and there are multiple fastening bolts 600. The method of connecting the first mounting base 100 to the test bench 400 of the vibration reduction performance testing equipment by fastening bolts 600 facilitates the installation or disassembly of the first mounting base 100, thereby improving the convenience of installing or disassembling the first mounting base 100.
[0051] In addition, the first mounting base 100 has multiple threaded through holes 103 around its center, and the test bench 400 of the vibration reduction performance testing equipment has multiple first threaded holes 401. The multiple first threaded holes 401 and the multiple threaded through holes 103 correspond one-to-one. The screw end of each fastening bolt 600 passes through its threaded through hole 103 and its corresponding first threaded hole 401 to fix the first mounting base 100 on the test bench 400 of the vibration reduction performance testing equipment.
[0052] In the above embodiment, the first mounting base 100 is fixed on the test bench 400 of the vibration reduction performance testing equipment by having the screw end of each fastening bolt 600 pass through the threaded through hole 103 and extend into the first threaded hole 401 in sequence. The arrangement of multiple threaded through holes 103, multiple first threaded holes 401 and multiple fastening bolts 600 improves the tightness and stability of the connection between the first mounting base 100 and the test bench 400 of the vibration reduction performance testing equipment.
[0053] In some embodiments, reference Figures 1 to 5 In this application, the first mounting base 100 and the second mounting base 200 are provided with second threaded holes 700 on their peripheral sidewalls. There are at least two second threaded holes 700 located on the same sidewall of the first mounting base 100 or the second mounting base 200. The number of second threaded holes 700 can be set according to the actual situation, and this application does not make a specific limitation on it.
[0054] In addition, the vibration damping performance testing fixture in this application also includes at least two movable rods 701, each movable rod 701 having an external thread 7011 and a length greater than the depth of the second threaded hole 700, the external thread being adapted to the second threaded hole 700. The depth of the second threaded hole 700 is only required to ensure that the rod body of the movable rod 701 with the external thread 7011 is stably fixed within it, and this application does not impose specific limitations on it.
[0055] In the above embodiments, since the first mounting base 100 and the second mounting base 200 have a certain mass, they are inconvenient to operate during movement or flipping. However, by opening second threaded holes 700 on the peripheral sidewalls of the first mounting base 100 and the second mounting base 200 respectively, it is convenient to screw the end of the moving rod 701 with the external thread 7011 into the second threaded hole 700. Then, the first mounting base 100 or the second mounting base 200 can be moved or flipped by means of the moving rod 701, thereby improving the convenience of the actual operation process and improving the operation efficiency. Moreover, this method is more labor-saving than lifting directly.
[0056] In some embodiments, the depth of the second threaded hole 700 in this application is 0.2 to 0.35 times the length or width of the first mounting base 100 and the second mounting base 200. A smaller depth of the second threaded hole 700 results in a shorter insertion length of the moving rod 701, leading to lower stability in the connection between the moving rod 701 and the second threaded hole 700. Since the second threaded holes 700 on the peripheral sidewalls of the first mounting base 100 and the second mounting base 200 are opposite to each other (i.e., if a second threaded hole 700 is formed on one sidewall of the first mounting base 100 or the second mounting base 200, a second threaded hole 700 is also formed on the opposite sidewall), to ensure that the second threaded holes 700 on the opposite peripheral sidewalls of the first mounting base 100 or the second mounting base 200 can connect with their corresponding moving rods 701, the depth of the second threaded hole 700 should be less than half the length or width of the first mounting base 100 and the second mounting base 200. Furthermore, to ensure stability, the second threaded hole 700 needs to have a certain depth. Within the scope given in this embodiment, the movable rod 701 can be inserted into the corresponding second threaded hole 700 and stably connected to the second threaded hole 700.
[0057] In some embodiments, the surfaces of both the first mounting base 100 and the second mounting base 200 in this application are provided with a rust-proof layer of a predetermined thickness; wherein, the rust-proof layer can be a galvanized layer, and specifically, it can be applied to the outer surfaces of the first mounting base 100 and the second mounting base 200 by spraying.
[0058] Furthermore, the preset thickness is 0.2cm to 0.4cm. A preset thickness that is too small will not effectively isolate the first mounting base 100 and the second mounting base 200, while a preset thickness that is too large may affect production costs. The 0.2cm to 0.4cm protective layer described in this application effectively isolates the first mounting base 100 and the second mounting base 200 from corrosion by the external environment, while also reasonably controlling production costs. The preset thickness can be set according to actual needs, and this application does not impose specific limitations on it.
[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
