[0046] See also Figure 1 , Figure 2 , is an oil tank sample 100 to be tested, with a bracket 100-1 welded on the side, a connecting hole is opened on the bracket, and the oil tank is fixed in the vehicle through the connecting hole. The lower part of the oil tank sample is connected to an oil pipe 100-2, and the oil is transported to the vehicle engine through the oil pipe 100-2.

[0047] See also Figure 3-Figure 7 An oil tank vibration test fixture provided in an embodiment of the present application includes: a transition plate 1, the transition plate 1 is provided with a mounting hole 11 that passes through from top to bottom; a support member 2, the support member 2 is arranged above the transition plate 1; a clamp body 3, the clamp body 3 is arranged above the support member 2, the clamp body 3 is a polyhedral cylinder, each side of the clamp body 3 is provided with a first connecting hole 31 connected to the oil tank sample, an oil plugging member 4, one end of the oil plugging member 4 is connected to the clamp body 3 through a second connecting hole 32 provided on each side of the clamp body 3, and the other end is sealed and connected to the oil pipe of the oil tank sample.

[0048] The oil tank vibration test fixture described in this embodiment is fixed to the electromagnetic vibration test bench through the mounting hole 11 on the transition plate 1. The support member 2 is a columnar body, preferably a cylindrical body, which is used to support the clamp body 3 above to ensure the normal assembly of the oil tank sample. The clamp body 3 is set as a polyhedron, and each face connects the first connecting hole 31 with the connecting hole on the oil tank bracket 100-1 through bolts to fix an oil tank sample, thereby realizing the simultaneous testing of multiple oil tank samples, saving the test cycle and improving the test efficiency.

[0049] During the vibration test of the oil tank sample, a certain amount of oil will be stored in the tank to simulate the operation of the actual vehicle, and an oil plug is needed to seal the oil pipe 100-2 at the bottom. The traditional fixture installs the oil plug on the bottom of the fixture, which is inconvenient to install and easily interferes with the vibration table. The oil tank vibration test fixture described in this embodiment fixes one end of the oil plug 4 to the side surface of the fixture through the second connecting hole 32, and the other end is connected to the oil pipe 100-2 at the bottom of the oil tank sample, and is sealed by a clamp, which is easier to install, prevents the oil pipe 100-2 from being damaged during vibration, and is not easy to interfere with the vibration table.

[0050] In some optional embodiments, a cushion block 5 is further included, and the cushion block 5 is connected between the clamp body 3 and the oil tank sample. Different types of vehicle models have oil tanks of different shapes, and the bracket 100-1 welded on the oil tank has different shapes according to the different installation locations inside the vehicle. Some brackets 100-1 will have a gap in the middle after being connected to the clamp body 3. In order to prevent the bracket 100-1 from being broken by vibration during the test, a cushion block is set between the clamp body 3 and the oil tank sample to enhance the rigidity of the bracket. Cushions 5 of different shapes can be designed according to the different shapes of the bracket 100-1, thereby improving the versatility of the clamp.

[0051] Preferably, each side of the clamp body 3 is provided with a third connection hole 33; the cushion block 5 is provided with a first mounting hole 51 which is mounted in cooperation with the third connection hole 33. The third connection hole 33 is connected to the first mounting hole 51 by bolts, so that the cushion block 5 is fixed to the clamp body 3, and the first mounting hole 51 is set as a sinking hole to accommodate the bolt head.

[0052] Preferably, the two ends of the cushion block 5 are provided with second mounting holes 52, and the cushion block 5 is connected to the oil tank sample through the second mounting holes 52. The second mounting holes 52 are connected to the connecting holes provided on the oil tank bracket 100-1 by bolts, so that the cushion block 5 is fixed to the bracket, thereby enhancing the rigidity of the bracket.

[0053] Preferably, the transition plate 1, the support member 2 and the clamp body 3 are all provided with a weight-reducing hole 6 at the center. The weight-reducing hole 6 is used to achieve lightweighting of the clamp.

[0054] Preferably, the transition plate 1, the support member 2 and the clamp body 3 are integrally formed. Integral forming can greatly improve the strength and durability of the clamp, and can also improve efficiency and shape complexity, and reduce processing time and workstations. In addition, integral forming can avoid key problems such as seams and oxidation, further improving the performance and reliability of the clamp.

[0055] Further preferably, the material of the transition plate 1, the support member 2 and the clamp body 3 is aluminum alloy. The density of aluminum alloy is only 1 / 3 of that of steel, and the strength is improved by work hardening or heat treatment, thereby achieving a high strength-to-weight ratio, reducing the overall weight of the clamp and ensuring the rigidity of the connection, greatly improving the installation efficiency, reducing the burden on the vibration equipment, and facilitating the vibration test.

[0056] Preferably, the clamp body 3 is a cube, and the four faces of the cube can fix four oil tank samples, which greatly improves the test efficiency.

[0057] Preferably, a chamfer is provided at the junction of two adjacent surfaces of the clamp body 3. The chamfer can not only improve the aesthetics of the product, but also reduce concentrated stress and increase the service life of the clamp.

[0058] Preferably, the mounting holes 11 are evenly arranged on the outer periphery of the transition plate 1. This allows the clamp to be evenly stressed on the vibration device, thereby ensuring the accuracy of data during the vibration test of the oil tank sample.

[0059] The working process of the oil tank vibration test fixture described in this embodiment is as follows: the first step is to use bolts to fix the fixture on the vibration equipment through the mounting hole 11; the second step is to connect the first connecting hole 31 with the connecting hole on the oil tank bracket 100-1 on one surface of the clamp body 3 by bolts, so as to fix the oil tank sample on the fixture; the third step is to screw one end of the oil plug 4 into the second connecting hole 32, and the other end is connected to the oil pipe 100-2 at the bottom of the oil tank sample, and sealed by a clamp; the fourth step is to repeat the operations from the second step to the third step on the other surfaces of the clamp body 3; the fifth step is to turn on the vibration equipment and perform a vibration test.
