[0030] The purpose of this application is to overcome the above-mentioned technical deficiencies and propose an engine vibration testing fixture and system to solve the technical problem of insufficient safety in the prior art.

[0031] To achieve the above-mentioned technical objectives, this application adopts the following technical solution:

[0032] Firstly, this application provides an engine vibration testing fixture, such as... Figure 1 As shown, Figure 1 This is a schematic diagram of the structure of an engine vibration testing fixture provided in an embodiment of this application.

[0033] An engine vibration testing fixture includes a vibration support 1, a mounting plate 2, and an adapter plate 3.

[0034] Vibration support 1, the vibration support 1 includes a horizontal mounting plate 11 and a vertical mounting plate 12 connected to each other;

[0035] Mounting disc 2, which is fixedly connected to the vertical mounting plate 12, has a toothed structure 21 on the outer surface of the end of the mounting disc 2 facing away from the vertical mounting plate 12;

[0036] The adapter plate 3 is fixedly connected to the vertical mounting plate 12 and is sleeved around the mounting plate 2.

[0037] The vibration support 1 in this application includes a horizontal mounting plate 11 and a vertical mounting plate 12. The horizontal mounting plate 11 and the vertical mounting plate 12 are respectively connected to the vibration platform and the test engine, thereby suspending the test engine above the vibration platform and avoiding axial friction between the input shaft and the test engine, as well as axial friction between the outer surface of the test engine and the horizontal mounting plate 11. This vibration testing fixture has a stable structure and is quick and convenient to install and use. It is characterized by high efficiency, safety, and stability.

[0038] The vibration support 1 is composed of a horizontal mounting plate 11 and a vertical mounting plate 12 connected to each other. This structure can provide a stable support frame for fixing and suspending the test engine.

[0039] Mounting disc 2 is fixedly connected to vertical mounting plate 12, and its outer surface facing away from vertical mounting plate 12 is provided with toothed structure 21. Toothed structure 21 can mate with the spline of engine input shaft to ensure that the engine maintains the correct position and stability during vibration test.

[0040] The adapter plate 3 is fixed to the vertical mounting plate 12 and fitted around the mounting plate 2. It can transmit the vibration generated by the vibration source (such as the vibration platform) to the mounting plate 2 and the engine, while protecting the engine from direct contact with the vibration platform, reducing unnecessary wear and damage.

[0041] By suspending the test engine in mid-air, axial friction and direct contact are avoided, reducing potential mechanical damage and accidents during the test. The design of the vibration support 1 ensures the stability of the entire test fixture, making the vibration test results more accurate and reliable.

[0042] In some embodiments of this application, the horizontal mounting plate 11 and the vertical mounting plate 12 are perpendicular to each other, and the vertical mounting plate 12 is fixed to the edge of the upper surface of the horizontal mounting plate 11.

[0043] In some embodiments of this application, a reinforcing rib 13 is also included, which connects the horizontal mounting plate 11 and the vertical mounting plate 12.

[0044] The vibration test fixture consists of three parts: a vibration support 1, an adapter plate 3, and a mounting plate 2. The vibration support 1 has a T-shaped structure, and a reinforcing rib 13 is designed at the right angle where the vertical mounting plate 12 connects to the horizontal mounting plate 11. It is integrally formed using cast aluminum material, which ensures the overall stability of the fixture and avoids excessive weight. The height of the vertical mounting plate 12 of the vibration support 1 must be greater than the outer diameter of the test engine to ensure that there is a certain gap between the test engine and the horizontal mounting plate 11 after installation.

[0045] The horizontal mounting plate 11 and the vertical mounting plate 12 are perpendicular to each other, forming a stable "T"-shaped structure. This structure helps to distribute and withstand the vibration load from the engine.

[0046] The reinforcing rib 13 connects the horizontal mounting plate 11 and the vertical mounting plate 12, enhancing the structural strength and stability of the entire vibration support 1. This design prevents twisting or deformation during vibration testing.

[0047] The vibration bracket 1 is made of cast aluminum in one piece, which not only ensures the overall stability of the tooling, but also avoids excessive weight of the tooling due to the lightweight properties of aluminum, making it easy to handle and install.

[0048] The height of the vertical mounting plate of the vibration bracket 1 is greater than the outer diameter of the test engine, ensuring that there is a certain gap between the test engine and the horizontal mounting plate 11 after installation. This can prevent the test engine from contacting the mounting plate during vibration and reduce friction and damage.

[0049] In some embodiments of this application, the horizontal mounting plate 11 is provided with a plurality of screw holes 14 and a plurality of through holes 15, and at least a portion of the screw holes 14 surround the through holes 15.

[0050] The horizontal mounting plate 11 has multiple screw holes 14 for engaging with the connecting bolts of the vibration platform. By fixing the vibration bracket 1 to the vibration platform with bolts, the stability and safety of the vibration testing fixture during vibration are ensured.

[0051] The horizontal mounting plate 11 also has multiple through holes 15, the main function of which is to reduce the overall weight of the tooling. This design ensures that weight reduction is achieved without sacrificing connection stability. This arrangement of screw holes 14 and through holes 15 optimizes the structural strength and weight of the tooling.

[0052] In some embodiments of this application, a plurality of first bolts are also included, the vertical mounting plate 12 has a through hole 15 at its center, the mounting disc 2 covers the through hole 15, the plurality of first bolts are distributed circumferentially along the mounting disc 2, and each first bolt penetrates the mounting disc 2 and is embedded in the vertical mounting plate 12.

[0053] Multiple first bolts are distributed circumferentially along the mounting plate 2. These bolts pass through the through holes 15 of the mounting plate 2 and are embedded in the vertical mounting plate 12. This arrangement ensures a secure connection between the mounting plate 2 and the vertical mounting plate 12.

[0054] The through hole 15 at the center of the vertical mounting plate 12 provides a precise positioning point for the mounting disc 2. When the mounting disc 2 covers the through hole 15, the edge of the through hole 15 helps the mounting disc 2 to align, ensuring the correct positional relationship between the mounting disc 2 and the vertical mounting plate 12.

[0055] The first bolt serves to fix the mounting plate 2, making it form a stable support structure with the vertical mounting plate 12, thereby ensuring the correct position and stability of the engine during vibration testing.

[0056] In some embodiments of this application, a plurality of second bolts are also included, which are distributed circumferentially along the adapter plate 3 and located around the first bolt, with each second bolt penetrating the adapter plate 3 and embedded in the vertical mounting plate 12.

[0057] Multiple second bolts are distributed circumferentially along the adapter plate 3 and located around the first bolts. The function of these second bolts is to further secure the adapter plate 3 to the vertical mounting plate 12, thereby enhancing the structural stability of the entire vibration test fixture.

[0058] The adapter plate 3 is a key component used to connect the engine and the vibration test fixture. It can adapt to different engine models and provides a flexible connection method.

[0059] In some embodiments of this application, a clamp is also included, which is sleeved around the mounting plate 2.

[0060] In some embodiments of this application, a coupling is further included, which is sleeved on the end of the mounting plate 2 and is engaged with the mounting plate 2.

[0061] The adapter plate 3 and mounting plate 2 are made of 45# steel to ensure the connection strength between the test engine and the tooling; the diameter of the adapter plate 3 is the same as the diameter of the test engine flange, ensuring that the test engine flange and the adapter plate 3 can be fixedly connected by clamps; the mounting plate 2 has a toothed structure 21, which meshes with the spline of the test engine input shaft, effectively fixing the test engine input shaft and avoiding axial friction between the input shaft and the test engine when the test engine is subjected to axial vibration test.

[0062] The clamp is fitted around the periphery of the mounting plate 2 to secure it to the engine flange. The clamp applies pressure to ensure a tight connection between the mounting plate 2 and the engine, preventing relative movement.

[0063] The coupling is fitted onto the end of mounting plate 2 and engages with it. The coupling connects the engine's input shaft to the vibration test fixture, ensuring that the engine's rotational power is transmitted to the vibration platform.

[0064] The adapter plate 3 and the mounting plate 2 are made of 45 steel, which has high strength and wear resistance, ensuring the stability and durability of the connecting parts in vibration tests.

[0065] The diameter of adapter plate 3 is the same as that of the test engine flange, ensuring that the two can be fixedly connected using clamps, simplifying the installation process.

[0066] Mounting disc 2 is designed with a toothed structure 21, which can engage with the spline of the engine input shaft. This connection method can effectively fix the input shaft and prevent axial slippage.

[0067] Secondly, this application also provides an engine vibration testing system, including a test engine and an engine vibration testing fixture as described in any embodiment of the first aspect, wherein the test engine is mounted on the engine vibration testing fixture.

[0068] In some embodiments of this application, the test engine is engaged with the mounting plate 2 via a coupling, the test engine is fixedly connected to the adapter plate 3 via a clamp, and the test engine is suspended on the horizontal mounting plate 11 of the vibration bracket 1.

[0069] During vibration testing, screws are used to fix the horizontal mounting plate 11 of the vibration bracket 1 to the vibration platform. Then, the first bolt and the second bolt are used to fix the adapter plate 3 and the mounting plate 2 to the vertical mounting plate 12 of the vibration bracket 1. After the fixture is fixed, clamps are used to horizontally fix the test engine to the adapter plate 3. The spline of the input shaft of the test engine meshes with the external gear of the mounting plate 2 through a coupling. After the test engine is installed, the vibration platform is started to conduct a functional vibration test.

[0070] The test engine is connected to the mounting plate 2 via a coupling, which allows power transmission between the engine's input shaft and the mounting plate 2. Simultaneously, the test engine is fixedly connected to the adapter plate 3 via clamps to ensure engine stability during vibration testing.

[0071] The test engine is suspended on the horizontal mounting plate 11 of the vibration support 1, which avoids axial friction between the input shaft and the test engine, and also avoids axial friction between the outer surface of the test engine and the horizontal mounting plate 11.

[0072] When conducting vibration tests, first use screws to fix the horizontal mounting plate 11 of the vibration bracket 1 to the vibration platform, and then use screws to fix the adapter plate 3 and the mounting plate 2 to the vertical mounting plate of the vibration bracket 1.

[0073] The test engine is horizontally fixed on the adapter plate 3 using clamps. The spline of the input shaft of the test engine meshes with the external teeth of the mounting plate 2 through a coupling, thereby achieving an effective connection between the test engine and the vibration test fixture.

[0074] After the test engine is installed, the vibration platform is started to conduct functional vibration tests to test the engine's performance and durability under various vibration conditions.
