Description

Technical Field

[0001] This utility model belongs to the field of vibration testing technology, and in particular relates to an adjustable tilt angle damping vibration testing device. Background Technology

[0002] In the field of vibration testing technology, various products (such as electronic components, automotive parts, and precision instruments) are often subjected to non-horizontal, tilted conditions during actual use, and their vibration resistance performance needs to be verified through tests simulating real-world conditions. However, existing vibration testing equipment has significant limitations and cannot meet diverse testing needs.

[0003] On the one hand, traditional devices are mostly fixed horizontal structures, which can only conduct vibration tests in the horizontal direction and cannot adjust the tilt angle of the test platform, making it impossible to simulate the stress and vibration environment of the product under tilt. For example, existing devices cannot accurately reproduce the tilt vibration conditions of vehicle-mounted equipment in scenarios such as vehicle climbing and bumping, resulting in a deviation between the test data and the actual use of the product, making it difficult to effectively assess the reliability of the product under real working conditions.

[0004] On the other hand, the existing device uses a fixed connection for product positioning structure, which makes loading and unloading products cumbersome and reduces test efficiency. In addition, some positioning structures are not stable enough. During vibration test, especially in non-horizontal tilted state, the product is prone to displacement, deviation or even slippage, which not only affects the accuracy of test data, but may also damage the product, increase test costs and risks, and urgently needs to be improved. Therefore, we propose an adjustable tilt angle vibration damping vibration test device. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned technical problems by providing an adjustable tilt angle damping vibration testing device, which achieves the effect of adjusting the tilt angle of the vibration test.

[0006] In view of this, the present invention provides an adjustable tilt angle damping vibration testing device, including a base plate, a support assembly, a mounting plate, and a positioning assembly. The support assembly is mounted on the upper surface of the base plate. The support assembly is used to support the vibration test product, and the angle of the vibration test product can be adjusted by replacing the support assembly. The mounting plate is disposed above the base plate, and the positioning assembly is disposed on the upper end of the mounting plate. The positioning assembly is used for detachable installation and positioning of the product to be subjected to vibration testing.

[0007] Furthermore, the support assembly includes a front upright plate disposed on the base plate, a rear upright plate disposed on the rear side of the front upright plate, the height of the front upright plate being lower than the height of the rear upright plate, and the lower ends of the front upright plate and the rear upright plate being detachably connected to the upper end of the base plate by bolts respectively.

[0008] Furthermore, the upper ends of the front upright plate and the rear upright plate are both set as slopes, and the upper ends of the front upright plate and the rear upright plate are attached to the lower end of the mounting plate. The upper ends of the front upright plate and the rear upright plate are detachably connected to the lower end of the mounting plate by means of bolts.

[0009] Furthermore, the positioning component includes a shock absorber mounted on the mounting plate. The shock absorber is detachably connected to the mounting plate by bolts. The upper end of the shock absorber is provided with a top panel. Both the upper and lower sides of the top panel are provided with stops. The stops are fixedly connected to the top panel by bolts.

[0027] Reference Figures 1 to 5 An adjustable tilt angle damping vibration testing device includes a base plate 2, a support assembly, a mounting plate 4, and a positioning assembly. The support assembly is mounted on the upper surface of the base plate 2. The support assembly is used to support the vibration test product, and the angle of the vibration test product can be adjusted by replacing the support assembly. The mounting plate 4 is located above the base plate 2, and the positioning assembly is located on the upper end of the mounting plate 4. The positioning assembly is used for detachable installation and positioning of the product to be subjected to vibration testing.

[0028] This application is approved. The support component is installed on the upper surface of the base plate 2. Its angle adjustment function changes the tilt state of the mounting plate 4, enabling vibration testing of a platform that was originally limited to horizontal vibration tests. The mounting plate 4, as the intermediate load-bearing structure, transmits the angle adjustment effect of the support component to the positioning component above. The positioning component then uses a detachable mounting structure to fix the product under test. During the vibration test, regardless of the tilt angle of the mounting plate 4, it ensures that the product maintains its preset posture, preventing displacement or posture changes due to vibration, thus enabling vibration tests at different tilt angles.

[0029] In the example of this application, the support assembly includes a front upright plate 1 disposed on the base plate 2, a rear upright plate 3 disposed on the rear side of the front upright plate 1, the height of the front upright plate 1 being lower than the height of the rear upright plate 3, and the lower ends of the front upright plate 1 and the rear upright plate 3 being detachably connected to the upper end of the base plate 2 by bolts respectively.

[0030] As a preferred example of this utility model, the support assembly utilizes the height difference between the front upright plate 1 and the rear upright plate 3 to achieve tilt angle adjustment. The front upright plate 1 is lower than the rear upright plate 3, and their lower ends are fixed to the base plate 2 by bolts, forming a support structure with a certain height difference. Due to the difference in height between the upright plates, a tilt angle is naturally formed when the mounting plate 4 is placed on the two upright plates. By replacing the front upright plate 1 or the rear upright plate 3 with different height specifications, the height difference between the two can be changed, thereby adjusting the tilt angle of the mounting plate 4 to meet the tilt angle requirements of different tests. The bolted connection method ensures a stable connection between the upright plate and the base plate 2, while also facilitating quick replacement of the upright plates as needed.

[0031] In the example of this application, the upper end of the front upright plate 1 and the upper end of the rear upright plate 3 are both set as inclined surfaces, and the upper ends of the front upright plate 1 and the rear upright plate 3 are attached to the lower end of the mounting plate 4. The upper ends of the front upright plate 1 and the rear upright plate 3 are detachably connected to the lower end of the mounting plate 4 by means of bolt fixing.

[0032] As a preferred example of this utility model, the inclined surfaces at the upper ends of the front upright plate 1 and the rear upright plate 3 match the lower end surface of the mounting plate 4, achieving surface contact through close fitting. This increases the contact area between the two, improving the stability and load-bearing capacity of the connection. During vibration testing, this surface contact structure effectively disperses the force, preventing relative slippage between the upright plates and the mounting plate 4, and ensuring that the tilt angle of the mounting plate 4 remains stable. The bolt-fixed detachable connection method ensures the robustness of the connection while facilitating the disassembly of the mounting plate 4 for maintenance, replacement, or adjustment when needed, making the device more flexible in use.

[0033] In the example of this application, the positioning component includes a shock absorber 5 disposed on the mounting plate 4. The shock absorber 5 is detachably connected to the mounting plate 4 by bolts. The upper end of the shock absorber 5 is provided with an upper panel 6. Both the upper and lower sides of the upper panel 6 are provided with blocks 7. The blocks 7 are fixedly connected to the upper panel 6 by bolts.

[0034] As a preferred example of this utility model, the shock absorber 5 in the positioning assembly is mounted on the mounting plate 4. When the vibration test is conducted, the shock absorber 5 absorbs and buffers the impact force and energy generated by the vibration, reducing the direct impact of the vibration on the product placed on the upper panel 6, thus protecting the product and stabilizing the vibration environment. The stops 7 on the upper and lower sides of the upper panel 6 are fixed with bolts, forming a mechanical limit on the product placed on the upper panel 6, preventing the product from shifting horizontally or slipping off the upper panel 6 during vibration.

[0035] In the example of this application, four shock absorbers 5 are provided, and the four shock absorbers 5 correspond to the four corners of the upper panel 6 respectively. The shock absorbers 5 are detachably connected to the upper panel 6.

[0036] As a preferred example of this utility model, four shock absorbers 5 are respectively arranged at the four corners of the upper panel 6, forming a symmetrical support structure. This structure can evenly distribute the weight of the upper panel 6 and the product onto each shock absorber 5, achieving uniform support. During vibration transmission, this symmetrical layout allows vibration energy to be evenly transmitted and absorbed through the four shock absorbers 5, preventing the upper panel 6 from tilting or the product from experiencing excessive local stress due to uneven force distribution.

[0037] In the example of this application, the front upright plate 1, the bottom plate 2, the rear upright plate 3, the mounting plate 4, and the top panel 6 are all made of lightweight, high-strength aluminum alloy 2A12-T4.

[0038] As a preferred example of this utility model, the selected lightweight high-strength aluminum alloy (model 2A12-T4) has low density, resulting in lighter components and a reduced overall weight, facilitating handling, installation, and relocation, while also reducing the load-bearing capacity requirements of the test site. Furthermore, the high tensile strength (approximately 470 MPa) and yield strength (approximately 325 MPa) of this aluminum alloy can withstand the interaction forces between components and the stresses generated by external vibrations during vibration testing, preventing deformation, breakage, or other damage to components. This ensures the structural stability of the device during long-term use and high-intensity testing, guaranteeing the safety and reliability of the tests.

[0039] In the example of this application, the middle part of the rear upright plate 3 is hollow, and the upper edge of the rear upright plate 3 is flush with the upper edge of the mounting plate 4.

[0040] As a preferred example of this utility model, the hollow structure in the middle of the rear upright plate 3 reduces the amount of material used and lowers the weight of the rear upright plate 3 itself without affecting its overall support strength, thereby reducing the overall weight of the device. The upper edge of the rear upright plate 3 is flush with the upper edge of the mounting plate 4, making the transition at the connection point smooth and avoiding protrusions or depressions caused by height differences. During the test operation, this flat structure prevents operators from being bumped by protruding parts, and at the same time provides a flat surrounding environment for product placement and positioning, avoiding interference with the test operation due to structural irregularities.

[0041] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
