Detailed Implementation

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] The following is for reference. Figures 1-4 A vibration testing device 100 according to an embodiment of the present invention is described. The vibration testing device 100 is used to be mounted on a vibration table for vibration testing. The vibration testing device 100 includes: Fixing base 10, the fixing base 10 is suitable for fixing to the vibration table; The mounting frame 20 is fixed to the fixing base 10 and extends along the first direction. The mounting frame 20 includes multiple frame segments 21, which are connected sequentially along the first direction. Each of the multiple frame segments 21 is used to fix and install the corresponding test piece.

[0020] The first direction is Figure 1 The X direction in the middle, the second direction is Figure 1 The Y-axis is perpendicular to both the first and second directions. The mounting base 10 is suitable for fixing to the vibration table. In some embodiments of this invention, the mounting base 10 and the vibration table can be fixedly connected by bolts, or by snap-fit ​​connection. However, this invention is not limited to these methods; the mounting base 10 and the vibration table can also be fixedly connected in other ways, as long as the mounting base 10 is fixed to the vibration table. As an intermediate connecting component, the mounting base 10 can be designed with standardized interfaces (such as T-slots or bolt hole arrays) for different types of vibration tables, enabling rapid clamping of the vibration testing device 100.

[0021] The mounting frame 20 is fixed to the fixing base 10 and extends along the first direction. The mounting frame 20 and the fixing base 10 can be rigidly and detachably connected by bolts, pins, etc., which can ensure that the vibration energy is efficiently transmitted to the test piece, reduce energy loss, and also allow for quick disassembly and replacement of the test piece, thus improving testing efficiency.

[0022] The mounting frame 20 includes multiple frame segments 21. In some embodiments of this invention, the mounting frame 20 may include two, three, four, or other numbers of frame segments 21. However, this invention is not limited to this, and the mounting frame 20 may also include other numbers of frame segments 21, as long as the mounting frame 20 includes multiple frame segments 21. The mounting frame 20 may be constructed as a cylinder, and the outer diameter of the mounting frame 20 may be R, satisfying the relationship: 44mm≤R≤46mm. It is made of non-magnetic aluminum alloy, which will not generate a magnetic field or be magnetized by an external magnetic field, thus avoiding interference with the electromagnetic signals of the test piece (such as an antenna or sensor) due to magnetization.

[0023] Multiple skeleton segments 21 are connected sequentially along a first direction. Each skeleton segment 21 is used to fix and install the corresponding test piece. Each skeleton segment 21 can independently fix one or more test pieces, realizing a parallel testing mode of "one skeleton, multiple test pieces". Taking the vibration screening of electronic components as an example, the vibration resistance verification of multiple PCB circuit boards can be completed simultaneously in a single test, greatly improving the testing efficiency, significantly shortening the total testing cycle of multiple test pieces, reducing the idle time of the vibration testing device 100, reducing hardware investment costs and labor costs, and enhancing the reliability and comparative analysis of the test data.

[0024] Multiple skeleton segments 21 can be integrally formed, and multiple test pieces can be installed on the same mounting skeleton 20, which can ensure that the vibration excitation (amplitude, frequency, phase) is consistent, so as to perform synchronous vibration testing on multiple test pieces that need to be used in the same vibration environment, and improve the correlation of vibration response of different test pieces.

[0025] Furthermore, the test pieces may include: gauges (accelerometers), PCB circuit boards (power boards, main control boards), fluxgates, and other types of test pieces.

[0026] According to some embodiments of the present invention, such as Figure 2 As shown, the multiple skeleton segments 21 include a first skeleton segment 22, and the sidewall of the first skeleton segment 22 is formed with a first mounting groove 23, which is used to embed and assemble the corresponding test piece.

[0027] The first frame segment 22 has a first mounting groove 23 formed on its sidewall. The size of the first mounting groove 23 is adapted to the size of the corresponding test piece, so that the first mounting groove 23 can be used to embed and assemble the test piece. The test piece can be a gauge. After the gauge is embedded in the first mounting groove 23, a pressure cap can be placed on the open end of the first mounting groove 23 to fix the gauge in the first mounting groove 23, which can effectively shield external electromagnetic interference. The first mounting groove 23 and the first frame segment 22 can be integrally molded to reduce energy loss at the connection interface and improve vibration energy transmission and data reliability. The first mounting groove 23 can be designed as a standard interface to support quick insertion and removal of the gauge, which can improve installation efficiency and testing efficiency.

[0028] According to some embodiments of the present invention, such as Figure 1 As shown, the first skeleton segment 22 also has a first mounting hole 24. The first mounting hole 24 and the first mounting groove 23 are located on the same side of the first skeleton segment 22. There are multiple first mounting holes 24, and the multiple first mounting holes 24 are arranged sequentially along the circumference of the first mounting groove 23.

[0029] In this invention, there are multiple first mounting holes 24. In some embodiments, there may be two, three, or four first mounting holes 24, but this invention is not limited to these numbers and may have other numbers of first mounting holes 24, as long as there are multiple first mounting holes 24. As a specific embodiment of this invention, there may be four first mounting holes 24, which are arranged sequentially along the circumference of the first mounting groove 23. A pressure cap may be provided on the open end of the first mounting groove 23, and the pressure cap may be fitted into the first mounting hole 24 by fasteners, so as to encapsulate the gauge within the first mounting groove 23. This can effectively shield external electromagnetic interference and prevent the gauge from falling off during the test, thereby improving the safety and reliability of the test process and effectively improving the test accuracy.

[0030] Fasteners can be bolts, pins, etc. As a specific embodiment of this utility model, the fastener can be a bolt. Bolt installation structure is simple, low cost, easy to disassemble and assemble, efficient to maintain, reliable connection, strong load-bearing capacity, and can ensure stable fastening assembly of the corresponding test piece.

[0031] According to some embodiments of the present invention, such as Figure 2 As shown, the plurality of skeleton segments 21 include a second skeleton segment 25. The sidewall of the second skeleton segment 25 is formed with a second mounting groove 26. The second mounting groove 26 is used to assemble the corresponding test piece. The second mounting groove 26 is formed with a second mounting hole 27.

[0032] The second frame segment 25 has a second mounting groove 26 formed on its side wall. The size of the second mounting groove 26 is adapted to the size of the corresponding test piece so that the second mounting groove 26 can be used to assemble the corresponding test piece. The second mounting groove 26 has a second mounting hole 27. The corresponding test piece can be a fluxgate magnet. After the fluxgate magnet is installed in the second mounting groove 26, it can be fixed in the second mounting groove 26 by fasteners passing through it and assembling it in the second mounting hole 27. The fasteners can be bolts, pins, etc., and can be reasonably selected and set according to the actual situation. As a specific embodiment of this utility model, the fasteners can be bolts. Bolt installation structure is simple, low cost, convenient to disassemble and assemble, efficient to maintain, reliable connection, strong load-bearing capacity, and can ensure stable fastening assembly of the corresponding test piece.

[0033] Furthermore, there can be multiple second mounting slots 26. All multiple second mounting slots 26 have the same structure and are used to install fluxgate magnets. Multiple second mounting slots 26 and multiple fluxgate magnets are assembled in a one-to-one correspondence. The specific number can be reasonably selected and set according to the actual situation.

[0034] According to some embodiments of the present invention, such as Figure 2 As shown, the second skeleton segment 25 has two groove sidewalls 28 that are opposite to each other and spaced apart along the second direction. Each groove sidewall 28 has a third mounting hole 29 formed therein. The third mounting hole 29 penetrates the corresponding groove sidewall 28 along the second direction. The third mounting hole 29 is used to assemble a clamping structure that clamps the corresponding test piece. The first direction and the second direction are perpendicular.

[0035] The first direction is Figure 2 The X direction in the middle, the second direction is Figure 2 The Y-direction, the first direction and the second direction are perpendicular. The second skeleton segment 25 has two groove sidewalls 28 that are opposite to each other and spaced apart along the second direction. Each groove sidewall 28 has a third mounting hole 29 formed therein. The third mounting hole 29 penetrates the corresponding groove sidewall 28 along the second direction. The third mounting hole 29 is used to assemble a clamping structure that clamps the corresponding test piece. By clamping the test piece with the clamping structure installed on the two groove sidewalls 28 respectively, radial pressure can be applied to the test piece to eliminate the gap between the test piece and the groove sidewall 28 in the radial direction, avoid the test piece from loosening in the radial direction, and further improve the installation stability of the test piece.

[0036] According to some embodiments of the present invention, such as Figure 2 As shown, the plurality of skeleton segments 21 include a third skeleton segment 30, and the sidewall of the third skeleton segment 30 is formed with a fourth mounting hole 31.

[0037] The third frame segment 30 has multiple fourth mounting holes 31 on its sidewalls, providing multiple mounting points for mounting the test piece. This ensures that the test piece is mounted uniformly and reliably on the third frame segment 30, providing mounting redundancy. Even if one mounting point fails, the other mounting points can still stably mount the test piece on the third frame segment 30. This prevents the test piece from shifting due to vibration or external forces, and prevents noise interference caused by poor contact or signal transmission interruption, ensuring that the collected vibration signal accurately reflects the dynamic characteristics of the test piece. During vibration testing, the test piece may be subjected to high-intensity impacts or centrifugal forces. Stable mounting prevents the test piece from falling off or colliding, avoiding damage to the test piece itself or other components of the vibration testing device 100.

[0038] According to some embodiments of the present invention, such as Figure 2 As shown, the multiple skeleton segments 21 also include a first skeleton segment 22 and a second skeleton segment 25. A third skeleton segment 30 is connected between the first skeleton segment 22 and the second skeleton segment 25. The first skeleton segment 22, the second skeleton segment 25 and the third skeleton segment 30 together define two third mounting slots 32. The two third mounting slots 32 are located on opposite sides of the third skeleton segment 30. A fourth mounting hole 31 is formed on both sides of the third skeleton segment 30 facing the two third mounting slots 32.

[0039] The first skeleton segment 22, the second skeleton segment 25, and the third skeleton segment 30 together define two third mounting slots 32. The two third mounting slots 32 are located on opposite sides of the third skeleton segment 30. The two third mounting slots 32 are used to install the test piece, which can be a PCB circuit board. The third skeleton segment 30 has fourth mounting holes 31 on both sides facing the two third mounting slots 32. The PCB circuit board is installed in the corresponding third mounting slot 32 by fasteners passing through it and being assembled into the corresponding fourth mounting holes 31.

[0040] Fasteners can be bolts, pins, etc., and can be reasonably selected and set according to actual conditions. As a specific embodiment of this utility model, the fastener can be a bolt. Bolt installation structure is simple, low cost, convenient to disassemble and assemble, efficient to maintain, reliable connection, strong load-bearing capacity, and can ensure stable fastening assembly of the corresponding test piece.

[0041] According to some embodiments of the present invention, such as Figures 2-4As shown, at least one skeleton segment 21 has a wiring structure 33. In some embodiments of this utility model, one, two, three, or other numbers of skeleton segments 21 may have wiring structures 33, and each skeleton segment 21 may also have a wiring structure 33. As a specific embodiment of this utility model, each skeleton segment 21 may have a wiring structure 33. By setting the wiring structure 33, a wiring harness for connecting the test piece and an external information acquisition device can be installed, so as to transmit the performance change information of the test piece during the vibration test to the external information acquisition device, thereby enabling effective analysis and processing to obtain the vibration test results.

[0042] like Figure 3 and Figure 4 As shown, a wiring structure 33 is formed between the first skeleton segment 22 and the third skeleton segment 30. A wiring structure 33 is also formed on the opposite side of the first mounting groove 23 on the first skeleton segment 22. Wiring structures 33 are provided at both ends of the third mounting groove 32 along the first direction. By setting the wiring structure 33, a wiring structure 33 is formed between the second skeleton segment 25 and the third skeleton segment 30. Wiring structures 33 are also provided between adjacent second mounting grooves 26. This allows the test piece on each skeleton segment 21 to be connected to an external information acquisition device via a wiring harness to obtain the performance change information of each test piece during the vibration test. This enables effective analysis and processing of the vibration test results of each test piece, greatly improving test efficiency, significantly shortening the total test cycle of multiple test pieces, reducing the idle time of the vibration testing device 100, reducing hardware investment costs and labor costs, and enhancing the reliability and comparative analysis of the test data.

[0043] According to some embodiments of the present invention, such as Figure 1 As shown, the vibration testing device 100 further includes: a clamp 40, a mounting base 10 having an assembly groove 11 open toward the mounting frame 20 on the side facing the mounting frame 20, the assembly groove 11 extending along a first direction, at least a portion of the mounting frame 20 being assembled in the assembly groove 11, the clamp 40 being located on the side of the mounting frame 20 away from the mounting base 10, and the clamp 40 being fixed to the mounting base 10 to clamp and fix the mounting frame 20.

[0044] The vibration testing device 100 further includes a clamp 40. The side of the fixed base 10 facing the mounting frame 20 has an assembly groove 11 that opens towards the mounting frame 20. The assembly groove 11 can be constructed as a "V" shape or a similar "V" shape structure. The assembly groove 11 extends along a first direction. At least a portion of the mounting frame 20 is assembled in the assembly groove 11. The mounting frame 20 is constructed as a cylinder. The symmetrical structure of the V-shaped groove (usually a 90° or 120° included angle) can automatically guide the cylinder to align along the center line without additional adjustment tools. The cylinder is constrained in the V-shaped groove with 5 degrees of freedom (only the axial movement degree of freedom is retained), which can effectively prevent the mounting frame 20 from rotating or shifting. The cylinder and the two inclined surfaces of the V-shaped groove form line contact or surface contact. The load is distributed and transmitted through the two contact points, which can avoid local stress concentration and thus reduce the risk of damage to the fixed base 10 and the mounting frame 20.

[0045] The clamp 40 is located on the side of the mounting frame 20 away from the fixed base 10. The clamp 40 is fixed to the fixed base 10 to hold and fix the mounting frame 20. Under the action of radial clamping force, the mounting frame 20 can effectively resist radial movement caused by external forces such as cutting force, centrifugal force or vibration, and enhance the stability of the mounting frame 20, so as to fix the mounting frame 20 more stably on the fixed base 10, laying a good test environment for subsequent vibration test and ensuring the accuracy of the test results.

[0046] According to some embodiments of the present invention, such as Figure 1 As shown, the clamp 40 has a fifth mounting hole 41, and the fixing base 10 has a sixth mounting hole 12 corresponding to the fifth mounting hole 41.

[0047] There can be multiple fifth mounting holes 41 and sixth mounting holes 12. The fifth mounting holes 41 on the clamp 40 correspond to the corresponding sixth mounting holes 12. Fasteners can be inserted through the fifth mounting holes 41 and assembled into the sixth mounting holes 12 to fix the clamp 40 to the fixing base 10. Specifically, along the second direction, multiple sixth mounting holes 12 are formed on both sides of the assembly groove 11 and arranged along the first direction. Along the second direction, each clamp 40 has a fifth mounting hole 41 at both ends. The fifth mounting holes 41 at both ends of the clamp 40 correspond to the positions of the corresponding sixth mounting holes 12 on both sides of the assembly groove 11.

[0048] The end of the clamp 40 facing the mounting frame 20 also has a "V-shaped groove," which can both clamp the mounting frame 20 and avoid the wiring structure 33 on the mounting frame 20 and the test piece. After the clamp 40 clamps the mounting frame 20, multiple fasteners can be respectively assembled into the corresponding fifth mounting holes 41 and their corresponding sixth mounting holes 12 on the multiple clamps 40 to fix the clamp 40 to the fixing base 10. The setting of multiple sixth mounting holes 12 provides multiple mounting points in the extension direction of the fixing base 10, which can meet the fixing of mounting frames 20 of different lengths, thereby effectively improving the compatibility and versatility of the vibration testing device 100.

[0049] There are multiple clamps 40 arranged along the first direction, which can clamp and fix the mounting frame 20 at multiple positions in the first direction, thereby further improving the installation stability of the mounting frame 20 and fixing the mounting frame 20 more stably on the fixing base 10. This lays a good test environment for subsequent vibration testing and further ensures the accuracy of the test results.
