Description

Technical Field

[0001] This utility model belongs to the field of acceleration testing, specifically relating to a non-disassembly multi-directional acceleration testing rotary platform. Background Technology

[0002] In the fields of product reliability verification and environmental adaptability assessment, acceleration testing is a crucial testing component. Such tests typically require applying loads along three mutually perpendicular axes (X, Y, Z) and six other directions (i.e., triaxial-six-directional) to comprehensively evaluate the product's structural strength, connection reliability, and the performance of internal components under complex dynamic environments. However, current acceleration testing methods suffer from significant efficiency bottlenecks and operational challenges when implementing multi-directional testing.

[0003] Disadvantages and shortcomings of existing technologies:

[0004] (1) Low test efficiency and frequent disassembly and installation operations are the main reasons for the extended test cycle. Each change of direction is accompanied by a large amount of bolt tightening / loosening, specimen handling, repositioning and precision adjustment (such as leveling and centering), which consumes a lot of time.

[0005] (2) The heavy workload of operators, the repetitive and tedious disassembly and assembly process greatly increases the physical labor intensity and time investment of on-site test personnel. Operators need to repeatedly perform high-precision positioning and fastening operations, which can easily lead to fatigue and may introduce human error.

[0006] (3) The preparation and adjustment time is long. Each reversal not only includes the actual disassembly and assembly time, but also a lot of preparation work (such as preparing new tooling and planning installation points) and fine adjustment time during the test (such as ensuring installation rigidity, avoiding over-constraint or under-constraint, and verifying that the installation status meets the test specifications), which further slows down the overall test progress.

[0007] (4) Poor versatility and flexibility: Most simple tooling or adapters are designed for specific specimens or limited orientations and lack adjustability. When testing specimens of different sizes and shapes or when more flexible orientation switching is required, new tooling is often required, which increases costs and preparation time and makes it impossible to quickly respond to diverse testing needs.

[0008] (5) Potential safety and quality risks: Frequent disassembly and assembly may lead to wear, loosening, or improper installation of connecting parts (such as bolts and threaded holes), increasing the risk of specimen detachment during the test, endangering the safety of test equipment and personnel, and potentially invalidating test data. Each reinstallation makes it difficult to guarantee that the position, orientation (such as verticality), and installation stiffness of the specimen on the vibration table are completely consistent, which may introduce deviations in test conditions and affect the comparability and accuracy of test results in different directions. Multiple disassembly and assembly operations may also cause unexpected physical damage to the specimen or its connecting interfaces. Utility Model Content

[0009] This invention aims to solve the problem of frequent disassembly and assembly caused by changes in test direction during acceleration testing, thereby improving test efficiency. This application, through optimized structural design, significantly reduces disassembly and assembly steps, effectively improving test efficiency and reducing the workload of operators.

[0010] To address the aforementioned problems in the existing technology, the technical solution adopted by this utility model is as follows:

[0011] A non-disassembly-free multi-directional acceleration testing rotary platform includes: a fixed plate, a horizontal rotating plate, and a mounting plate;

[0012] The fixing plate is provided with fixing holes, and the fixing plate is rotatably connected to a horizontal rotating plate;

[0013] The horizontal rotating plate is provided with a lower connecting hole, and the horizontal rotating plate is rotatably connected to the mounting plate through a rotating shaft;

[0014] The mounting plate is provided with mounting holes and upper connection holes, and a support rod is detachably connected between the mounting plate and the horizontal rotating plate.

[0015] By setting up a fixed plate and connecting it to the rotating plate of the instrument, and then setting a horizontal rotating plate on the fixed plate, the acceleration of the device under test at multiple angles in the horizontal direction can be tested without disassembling the device under test.

[0016] By setting up a mounting plate, the device under test can be connected to the mounting plate, and the mounting plate can rotate relative to the horizontal rotating plate, so acceleration in more directions can be tested in addition to the horizontal direction.

[0017] Furthermore, the support rod is connected to the mounting plate and the fixing plate by fastening bolts. The fastening bolts include horizontal fastening bolts, fixed fastening bolts, and vertical fastening bolts. One end of the support rod is connected to the mounting plate by a fixed fastening bolt, and the other end of the support rod is connected to either a horizontal rotating plate by a vertical fastening bolt or a horizontal fastening bolt to the mounting plate. The mounting plate is provided with a storage groove for accommodating the support rod.

[0018] Furthermore, both the mounting plate and the horizontal rotating plate are equipped with handles, which are connected to the ends of the mounting plate and the fixed plate away from the rotating shaft. The handles facilitate the movement of the entire device.

[0019] Furthermore, the storage slot is located on the side of the mounting plate closest to the fixing plate, and the mounting hole is located on the side of the mounting plate away from the fixing plate. The fixing plate has a circular structure, and its edge is provided with a rotating groove. The horizontal rotating plate is provided with a limiting block that matches the rotating groove.

[0020] The beneficial effects of this utility model are as follows:

[0021] 1. This utility model has an ingenious structure, which can complete the acceleration test of the device under test in multiple directions without disassembling the device under test, thereby improving work efficiency.

[0022] 2. Through structural improvements, this utility model can not only perform acceleration tests in the horizontal direction, but also in the Z-axis direction, resulting in more comprehensive test data.

[0023] 3. This utility model provides a convenient direction change function, simplifies the test process, and significantly shortens the test preparation and adjustment time.

[0024] 4. This utility model has good adjustability and versatility design, and can meet the testing requirements of different specimens and multi-directional tests through structural adaptation, ensuring stable support and safety and reliability in the testing process. Attached Figure Description

[0036] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0037] Example 1:

[0038] like Figure 1 , 2 As shown in Figure 6, a non-disassembly multi-directional acceleration testing rotary platform includes: a fixed plate 1, a horizontal rotating plate 2, and a mounting plate 3;

[0039] The fixing plate 1 is provided with fixing holes 11, and the fixing plate 1 is rotatably connected to a horizontal rotating plate 2;

[0040] The horizontal rotating plate 2 is provided with a lower connecting hole 21, and the horizontal rotating plate 2 is rotatably connected to the mounting plate 3 through a rotating shaft 4;

[0041] The mounting plate 3 is provided with mounting holes 31 and upper connecting holes 32, and a support rod 5 is detachably connected between the mounting plate 3 and the horizontal rotating plate 2.

[0042] By setting a fixed plate 1 and connecting it to the rotating plate 8 of the instrument, and then setting a horizontal rotating plate 2 on the fixed plate 1, the acceleration of the device under test at multiple angles in the horizontal direction can be tested without disassembling the device under test.

[0043] By setting up mounting plate 3, the device to be tested can be connected using mounting plate 3, and mounting plate 3 can rotate relative to horizontal rotating plate 2, so acceleration in more directions can be tested in addition to the horizontal direction.

[0044] In practical use, it is usually necessary to test acceleration in three directions: X, Y, and Z. If positive and negative directions are added, there are accelerations in six directions. First, by rotating the horizontal rotating plate 2 90° each time, the acceleration in the four horizontal directions (X and Y) can be tested. Then, by raising the mounting plate 3 and rotating the horizontal rotating plate 2 180° each time, the acceleration in the two directions (Z) can be tested.

[0045] Example 2:

[0046] Based on Embodiment 1, the support rod 5 is connected to the mounting plate 3 and the fixing plate 1 by fastening bolts.

[0047] The fastening bolts include horizontal fastening bolts 71, fixed fastening bolts 72, and vertical fastening bolts 73. One end of the support rod 5 is connected to the mounting plate 3 via the fixed fastening bolt 72, and the other end of the support rod 5 is connected to the horizontal rotating plate 2 via the vertical fastening bolt 73 or to the mounting plate 3 via the horizontal fastening bolt 71. One end of the support rod 5 is always connected to the fixed fastening bolt 72. When the other end of the support rod 5 is connected to the vertical fastening bolt 73, the mounting plate 3 is in a vertical state; when the other end of the support rod 5 is connected to the horizontal fastening bolt 71, the mounting plate 3 is in a horizontal state.

[0048] The mounting plate 3 is provided with a storage groove 33 for storing the support rod 5.

[0049] When it is necessary to test the acceleration in the Z direction, the mounting plate 3 needs to be erected (at an angle of 90° with the horizontal rotating plate 2). In order to ensure the stability of the mounting plate 3 after it is erected, a support rod 5 is used for support. At this time, one end of the support rod 5 is connected to the mounting plate 3 by a fixing bolt 72, and the other end of the support rod 5 is connected to the horizontal rotating plate 2 by a vertical fixing bolt 73.

[0050] When it is necessary to test the acceleration in the X / Y directions, the mounting plate 3 needs to be laid flat (with an angle of 0° with the horizontal rotating plate 2). At this time, one end of the support rod 5 is connected to the mounting plate 3 by the fixing bolt 72, and the other end of the support rod 5 is connected to the mounting plate 3 by the horizontal fixing bolt 71. The support rod 5 is located in the storage groove 33. The mounting plate 3 and the horizontal rotating plate 2 are connected by the upper connecting hole 32 and the lower connecting hole 21.

[0051] Example 3:

[0052] Based on Embodiment 2, both the mounting plate 3 and the horizontal rotating plate 2 are connected to handles 6, which are connected to the end of the mounting plate 3 and the fixing plate 1 away from the rotating shaft 4.

[0053] The addition of handle 6 facilitates the movement of the entire device.

[0054] Example 4:

[0055] Based on Example 3, such as Figure 3-5 As shown, the storage slot 33 is located on the side of the mounting plate 3 near the fixing plate 1, and the mounting hole 31 is located on the side of the mounting plate 3 away from the fixing plate 1.

[0056] The mounting plate 3 is divided into an inner side and an outer side (the inner side refers to the side that is closer to the horizontal rotating plate 2 when it is fastened, and the outer side refers to the side that is farther away from the horizontal rotating plate 2 when it is fastened). The inner side is provided with a storage groove 33 for connecting the support rod 5, and the outer side is provided with a mounting hole 31 for connecting the equipment.

[0057] The fixed plate 1 has a circular structure and a rotating groove 12 around its edge. The horizontal rotating plate 2 has a limiting block 22 that fits the rotating groove 12. The horizontal rotating plate 2 is made of two connecting plates. During installation, the limiting block 22 of the fixed plate 1 needs to be placed into the rotating groove 12 of the connecting plate first, and then the two connecting plates are welded together to form the horizontal rotating plate 2.

[0058] Specific working principle:

[0059] During connection, first connect the test rotating platform to the rotating plate 8 of the test instrument (the rotating plate 8 is the existing structure of the rotation acceleration test machine, which can be directly used here). Connect the rotating plate 8 using the fixing hole 11 on the fixing plate 1. Then, fasten the mounting plate 3. Use screws to connect the mounting plate 3, the horizontal rotating plate 2 and the rotating plate 8 through the upper connecting hole 32 and the lower connecting hole 21. Finally, connect the device under test to the mounting hole 31.

[0060] When performing acceleration tests in the X / Y directions, start the instrument and rotate the rotating plate 8 to test the equipment's operation under acceleration. After completing the acceleration test in one direction, remove the screws from the upper connecting hole 32 and the lower connecting hole 21, rotate the horizontal rotating plate 2 by 90°, and at this time, the mounting plate 3 will rotate the equipment by 90°. Then reconnect the screws and perform the acceleration test in the next direction. In this way, complete the four acceleration tests in the horizontal direction one by one.

[0061] When performing the acceleration test in the Z direction, first erect the mounting plate 3 of the equipment, and then use the support rod 5 for support so that the angle between the mounting plate 3 and the horizontal rotating plate 2 is 90°. Finally, use screws and the lower connecting hole 21 to connect the horizontal rotating plate 2 and the rotating plate 8. Then start the testing instrument to perform the acceleration test in the Z direction. After the test is completed, rotate the horizontal rotating plate 2 180° to perform the test in the opposite Z direction.

[0062] This utility model is not limited to the above-mentioned optional embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in its shape or structure, any technical solution that falls within the scope of the claims of this utility model shall be protected by this utility model.
