Description

Technical Field

[0001] The utility model belongs to the technical field of military power supply testing, and in particular relates to a clamp for a military power supply vibration test. Background Art

[0002] Military power supplies are widely used in the fields of communications, transportation, aviation and navigation, processing industry, etc. They have the advantages of stronger adaptability and concealment. Compared with ordinary power supplies, their use environment is relatively harsh and have higher requirements for environmental adaptability. They are often used in airplanes, tanks and other military transportation vehicles, so it is necessary to test the vibration resistance of military power supplies. The commonly used detection method is to simulate various bumps or vibration excitation states in the laboratory, so as to test the vibration resistance through vibration tests. During the test, it is usually necessary to fix the military power supply on the vibration equipment, but due to the shape and performance requirements of the military power supply, there are many problems in fixing the military power supply.

[0003] The utility model with application number CN202321356973.X mentions a tooling fixture for vibration testing of military power supplies, including a main frame and a positioning assembly. The main frame is used to be fixed on a vibration test bench. The main frame is made of steel plate material. The main frame has an installation groove, which is used to accommodate the military power supply. The positioning assembly is used to fix the military power supply in the installation groove of the main frame. It is mainly installed by means of the installation groove, and the fixing effect is not good. At the same time, there is no corresponding limit setting for the plug on the military power supply, and the use effect is not good.

[0004] The utility model with application number CN202022190468.5 mentions a rotatable and transformable maze toy, a power supply fixing structure for a military power supply box, comprising a power supply box body, wherein slide grooves are respectively provided at symmetrical positions on the front and rear sides of the inner bottom of the power supply box body, and two sliders are arranged inside the slide grooves. The upper surfaces of the sliders are fixedly connected to the limit plates, and a groove is provided at the bottom end of one side of the limit plate. A cross plate is arranged inside the groove, and the cross plate is fixedly installed at the bottom ends of the left and right sides of the battery. The left and right inner walls of the slide grooves are respectively fixedly connected to springs, and one end of the spring is fixedly connected to one side of the slider, which fixes the military power supply by the pressure of the spring. Due to the characteristics of the spring, it is not suitable for vibration testing and has a relatively short service life.

[0005] Therefore, there is an urgent need for a military power supply vibration test fixture that can fix the military power supply and maintain its stability during the vibration test, thereby making the vibration test results more accurate. Utility Model Content

[0006] In view of this, the utility model proposes a military power supply vibration test fixture, which is applied to the technical field of military power supply testing to solve the existing technical problems of poor fixing effect, large test experiment errors and no plug through hole.

[0007] In order to achieve the above technical purpose, the specific technical solution adopted by the utility model is:

[0008] A clamp for a military power supply vibration test is used to fix the test power supply, including a base plate, a mounting bracket and reinforcing ribs. The mounting bracket is arranged perpendicular to the base plate and fixedly connected to the base plate. The reinforcing ribs are arranged on one side of the mounting bracket and support the side wall of the mounting bracket. The test power supply is arranged vertically downward inside the mounting bracket. Three vertically extending connecting plates are arranged inside the mounting bracket. The three connecting plates are connected to the outer shell of the test power supply through mounting threaded holes arranged on the outer ring. The connecting plates are provided with plug through holes for accommodating a power plug arranged on the test power supply to pass through.

[0009] Furthermore, the connection plates on both sides of the three connection plates are fixedly connected to the connection plate in the middle and are bent forward relative to the connection plate in the middle, and the shape of the rear side of the test power supply matches the shape of the three connection plates.

[0010] Furthermore, the reinforcing ribs are fixedly connected to the side walls of the middle connecting plate.

[0011] Furthermore, the plug through holes are arranged on the connecting plates located on both sides.

[0012] Furthermore, the bottom plate is provided with a plurality of lower plate fixing holes located on both sides of the mounting bracket in the horizontal direction.

[0013] Furthermore, a fixed frame surrounding the test power supply is provided on the test power supply, and a plurality of frame through holes matching the positions of the mounting threaded holes are provided on the fixed frame.

[0014] Furthermore, the shape of the fixed frame is a rectangle, and the distribution shape of the plurality of frame through holes around the test power supply is also a rectangle.

[0015] By adopting the above technical solution, the utility model can also bring the following beneficial effects:

[0016] 1. The utility model ensures that the mounting bracket can be in close contact with the side wall of the test power supply through the three connecting plates on the mounting bracket, and connects the mounting bracket and the test power supply through the threaded holes arranged on the connecting plates, and connects the mounting bracket to the vibration test equipment through the lower plate fixing holes on the bottom plate, which can ensure the rigid connection of the test power supply, the mounting bracket, the bottom plate and the vibration test equipment during the test, thereby facilitating the transmission of vibration and making the detection of the vibration test more accurate.

[0017] 2. The utility model fixes the test power supply through the base plate and the mounting bracket, and has the advantages of simple structure, convenient disassembly and assembly, and high reliability. Compared with the existing vibration fixture, not only the vibration test effect is better, but also a corresponding plug through hole is provided for the power plug on the test power supply, which is more convenient for fixing the test power supply, can promote the advancement of military power supply vibration detection technology, increase the service life of military power supplies, effectively promote the development of military power supply related industries, and has broad application prospects.
