Description

Technical Field

[0001] The utility model relates to the technical field of radiators in aviation power supplies, and in particular to a radiator pressure test inspection tool. Background Art

[0002] Aviation power supplies usually include generators, batteries, and distribution systems. The generator is the main power source, usually driven by the aircraft's engine to generate alternating current (AC) or direct current (DC). The battery serves as a backup power source to provide power when the generator fails or the aircraft is parked on the ground. The distribution system is responsible for distributing power to various electrical equipment and ensuring a stable supply of power. The radiator is mainly composed of inner fins, outer fins, seals, cover plates, slotted aluminum, and composite plates, and contains many parts. After assembling this radiator, it is usually necessary to conduct an airtightness test to ensure the pass rate of the radiator.

[0003] Since the inner diameters of the two aluminum pipe joints installed on the aluminum grooves at both ends of the radiator are relatively large, it is difficult to dock with the existing air pipe joints, so the entire operation process is very complicated.

[0004] According to patent publication number CN212082727U, a radiator pressure test inspection tool includes a nylon clamp, a sleeve, a silicone pad, a pressure head and an aluminum pipe joint for installation on grooved aluminum. The nylon clamp is a two-half structure, which is sleeved on the outer wall of the aluminum pipe joint. The upper part of the outer wall of the aluminum pipe joint is provided with an annular protrusion for preventing the nylon clamp from sliding upward. The sleeve is sleeved on the outside of the nylon clamp, the upper part of the inner cavity of the sleeve is provided with an internal thread, and the lower part of the inner cavity of the sleeve is provided with an annular convex edge I. The upper part of the outer peripheral wall of the nylon clamp is provided with an annular convex edge II for the annular convex edge I to be built, and the lower part of the outer peripheral wall of the pressure head is provided with an external thread matching the internal thread. The pressure head is provided with a through hole communicating with the inner cavity of the aluminum pipe joint along its own axial direction. The silicone pad is located between the aluminum pipe joint and the pressure head. The bottom of the pressure head is provided with a step for pressing the silicone pad tightly against the top end face of the aluminum pipe joint, and the silicone pad is provided with a through hole connecting the through hole and the inner cavity of the aluminum pipe joint. The utility model facilitates the detection of the pressure bearing capacity of the radiator, ensuring the quality while improving the detection efficiency.

[0005] In the above publication number CN212082727U, the sealing performance of the connection between the aluminum tube structure and the air pipe joint is low, resulting in air leakage; at the same time, since the current radiator cannot adapt to the installation and fixation of different types of aviation power supplies, the practicality is reduced.

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0027] like Figure 1 As shown, the utility model provides a radiator pressure test inspection tool, including a radiator 1, both left and right ends of the radiator 1 are fixedly connected with a groove aluminum 2, the upper surface of the groove aluminum 2 is penetrated and fixedly connected with an aluminum tube 3, the outer surface of the aluminum tube 3 is provided with a joint 4, the upper surface of the joint 4 is penetrated and fixedly connected with an air pipe 5, and the side of the groove aluminum 2 away from the radiator 1 is fixedly connected with a fixing component 6;

[0028] When the air tightness of the radiator needs to be checked, the joint 4 is provided to facilitate the connection and limit fixation of the aluminum tube 3, and at the same time, it has a sealing effect. The air pipe 5 is provided to allow external gas to enter the interior of the radiator 1. At this time, the radiator 1 is placed in water to complete the air pressure sealing test of the inside of the radiator 1. The fixing component 6 is provided to facilitate the connection and fixation of the aviation power supply.

[0029] like Figure 2 - Figure 3 As shown, the joint 4 has an installation cavity 41 in its interior, the interior and exterior of the installation cavity 41 are communicated with each other below the inner wall, a metal tube 42 is fixedly connected to the upper inner wall of the installation cavity 41, a plug 43 is fixedly connected to the lower end of the metal tube 42, an elastic rubber ring 44 is fixedly connected to the upper inner wall of the installation cavity 41, a sealing rubber block 31 is fixedly connected to the upper outer surface of the aluminum tube 3, a rubber ring 32 is sleeved on the upper outer surface of the aluminum tube 3, the sealing rubber block 31 is in the shape of a conical column, and the inner wall of the installation cavity 41 is fixedly connected to the upper inner wall of the aluminum tube 3. The wall is threadedly connected to the outer surface of the aluminum tube 3, the upper end of the aluminum tube 3 is overlapped and pressed against the lower surface of the elastic rubber ring 44, the lower surface of the installation inner cavity 41 is overlapped and pressed against the upper surface of the rubber ring 32, the lower surface of the rubber ring 32 is overlapped and pressed against the outer surface of the sealing rubber block 31, the material of the plug 43 is rubber, the outer surface of the plug 43 is overlapped and pressed against the inside of the aluminum tube 3, the upper surface of the plug 43 is provided with a through hole 431 communicating with each other from top to bottom, and a conical surface 432 is provided below the outer surface of the plug 43;

[0030] When in use, the inner cavity 41 is installed and fixed with the aluminum tube 3 by threading, and the metal tube 42 is inserted into the interior of the aluminum tube 3. Due to the setting of the tapered surface 432 in the plug 43, it is easy to enter the interior of the aluminum tube 3. At this time, the plug 43 is deformed so that the outer surface is tightly fitted with the inner wall of the aluminum tube 3, thereby having a primary seal. At the same time, the upper end of the aluminum tube 3 is squeezed and contracted with the elastic rubber ring 44 and tightly fitted to have a secondary seal. When the joint 4 rotates, it pushes the rubber ring 32 to slide downward on the surface of the aluminum tube 3, so that the rubber ring 32 squeezes and contracts the sealing rubber block 31, thereby deforming, thereby having a triple seal effect, effectively preventing gas leakage at the connection after the gas enters, and the joint 4 is in the shape of a diamond block, which is easy to tighten or loosen.

[0031] like Figure 4 As shown, the fixing assembly 6 includes a mounting plate 61, a T-shaped slide groove 62 communicating with each other is provided on the front of the mounting plate 61, a T-shaped block 63 is slidably connected to the front and rear sides of the interior of the T-shaped slide groove 62, the horizontal outer surface of the T-shaped block 63 extends to the outside of the mounting plate 61, a fixing bolt 64 is threadedly connected to the interior of the T-shaped block 63 in the horizontal direction, and a plurality of T-shaped limit grooves 65 communicating with each other are provided on the upper surface of the mounting plate 61, wherein the limit assembly 66 is inserted into the interior of two T-shaped limit grooves 65;

[0032] When installation is required, the T-block 63 is moved so that it slides inside the T-shaped slot 62, thereby driving the fixing bolt 64, so that the fixing bolt 64 is easy to connect and fix, and then the limiting component 66 is inserted into the mounting plate 61 and passes through the inside of the T-block 63, so as to limit and fix the position of the T-block 63, so that the radiator 1 can be installed in different types of aviation power supplies.

[0033] like Figure 5 As shown, the limiting assembly 66 includes a rubber plate 661, the outer surface of the rubber plate 661 is fixedly connected to a metal block 662, and the outer surfaces of the rubber plate 661 and the metal block 662 are plugged into the vertical inner part of the T-shaped block 63;

[0034] The rubber plate 661 is inserted into the interior of the mounting plate 61 and the T-shaped block 63 to cause deformation and contraction. Due to the elasticity after deformation and contraction, the rubber plate 661 and the metal block 662 are tightly fitted to the inner walls of the mounting plate 61 and the T-shaped block 63, thereby having a restrictive effect.

[0035] The following is a detailed description of the working principle of the radiator pressure test inspection tooling.

[0036] When in use, the inner cavity 41 is installed to connect and fix with the aluminum tube 3, and the metal tube 42 is inserted into the inside of the aluminum tube 3. Since the plug 43 enters the inside of the aluminum tube 3, it has a primary sealing phenomenon.

When the joint 4 rotates, it pushes the rubber ring 32 to slide downward on the surface of the aluminum tube 3, so that the rubber ring 32 squeezes and contracts the sealing rubber block 31, so as to have a triple sealing effect. When installation is required, the T-block 63 is moved to make the T-block 63 slide inside the T-shaped slide groove 62, thereby driving the fixing bolt 64, and then the limiting component 66 is inserted into the mounting plate 61 and passes through the inside of the T-block 63, so as to facilitate the effect of limiting and fixing the position of the T-block 63.

[0037] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
