Description

Technical Field

[0001] The utility model relates to the technical field of vehicle parts detection, in particular to a tool for detecting the sealing performance of sheet metal and a plugging cover. Background Art

[0002] Traditional waterproof testing equipment such as Figure 1 As shown, it is a huge and straight barrel structure. In order to cover the measuring area of ​​the sheet metal to be tested, the outer diameter of the 500mm water column is 200mm and the inner diameter is 170mm. 11kg of water needs to be injected for one test. The sheet metal to be tested is placed under the huge water column for waterproof testing. There are problems such as wastewater detection, difficulty in water injection, low chassis that is not convenient for observing water leakage and difficulty in moving.

[0003] Based on the pressure formula of P=ρgh, the water pressure is related to the height. Therefore, the waterproof detection requirements of the same water pressure can be met without setting a water column with such a large diameter.

[0004] Based on this, it has become a top priority for technicians in this field to propose a convenient, intuitive and water-saving detection tool. Utility Model Content

[0005] The utility model aims to provide a waterproof detection tool which is intuitive in waterproof detection and uses less water resources.

[0006] In order to achieve the above-mentioned purpose, the utility model proposes a sheet metal and plug cover sealing detection tool, including a base, a detection table, a water column and a water pipe;

[0007] The testing platform is arranged on the base, a through hole is arranged on the surface of the testing platform, a water reservoir is arranged on the bottom surface of the testing platform, and the water reservoir is connected to the through hole;

[0008] The water column is connected to the water reservoir through a water pipe.

[0009] Furthermore, the water column is erected on the base through a bracket; the outer diameter of the water column is 30 mm and the inner diameter is 14.5 mm.

[0010] Furthermore, a through slot is provided on the surface of the base, and the slot accommodates the water reservoir and the connecting piece between the water reservoir and the pipeline.

[0011] Furthermore, the side edge of the testing platform is movably connected to the side edge of the base through a hinge, so that the testing platform can be folded relative to the base;

[0012] An exhaust valve is installed on the bottom surface of the water reservoir facing away from the testing platform.

[0013] Furthermore, a plurality of positioning clips are installed around the through holes on the surface of the testing platform.

[0014] Furthermore, the surface of the testing table and the bottom surface of the base are both equipped with supporting feet.

[0015] Furthermore, the bottom of the reservoir is made into an inclined surface, and a drain valve is installed at the lowest position of the inclined surface.

[0016] Furthermore, the water column and the water pipe are connected via a throttle valve.

[0017] Furthermore, a sealing ring is installed between the overlapping surfaces of the water reservoir and the test bench; and a sealing ring is arranged around the through hole to achieve sealing with the sheet metal to be tested.

[0018] Compared with the prior art, the advantages of the present invention are:

[0019] 1. Compared with the water column of the existing detection tooling, the water column of the utility model has a greatly reduced diameter, but the height remains unchanged, which can ensure that the water pressure during sheet metal and plugging cover detection is the same as that of the existing technology, but the water consumption is greatly reduced.

[0020] 2. The utility model improves the structure of the detection tooling, and transfers the sheet metal from the original bottom detection to the top detection of the tooling, making the detection observation more intuitive and improving the detection efficiency.

[0021] 3. Based on the technical structure of the sheet metal being detected above the tooling, the utility model further designs a flippable structure for the test bench, and further installs an exhaust valve at the bottom of the water reservoir, so that all the air inside the water reservoir is discharged, effectively avoiding the influence of air on the detection.

[0027] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be further described below.

[0028] The utility model provides a sheet metal and plug cover sealing detection tool, comprising a base 1, a detection table 2, a water column 3 and a water pipe 4;

[0029] like Figure 2 and Figure 3 As shown, the surface of the detection platform 2 is provided with a through hole 5, such as Figure 4 and Figure 5 As shown, a water reservoir 6 is provided on the bottom of the test bench 2, and the water reservoir 6 is connected to the through hole 5. An exhaust valve 7 and a drain valve are provided at the bottom of the water reservoir 6. For convenience, the utility model adopts a three-way valve, one side of which is an exhaust port and the other side is a drain port. In order to ensure the drainage effect, an inclined surface is made at the bottom of the water reservoir 6, and the valve is installed at the lowest position. A plurality of positioning clips 12 are installed around the through hole 5 on the surface of the test bench 2, such as Figure 2 As shown, the sheet metal 11 to be tested is fixed on the testing platform 2 by a positioning frame. In order to ensure the sealing effect, a sealing ring is installed between the overlapping surfaces of the water reservoir 6 and the testing platform 2; a sealing ring is provided around the through hole 5 to achieve sealing with the sheet metal 11 to be tested.

[0030] In this embodiment, the side edge of the test platform 2 is movably connected to the side edge of the base 1 through the hinge 8, so that the test platform 2 can be folded relative to the base 1. In order to ensure the support of the test platform 2 after folding, the surface of the test platform 2 and the bottom surface of the base 1 are both equipped with feet. Figure 4 As shown, a through slot 9 is provided on the surface of the base 1, and the slot 9 accommodates the water reservoir 6 and the connection piece between the water reservoir 6 and the pipeline.

[0031] In this embodiment, the water column 3 is erected on the base 1 through a bracket 13; the outer diameter of the water column 3 is 30 mm and the inner diameter is 14.5 mm; the bottom of the water column 3 is connected to the water reservoir 6 through a water pipe 4, and the water column 3 and the water pipe 4 are connected through a throttle valve 10.

[0032] The detection method of the utility model is as follows: Figure 2 and Figure 3 As shown, after the sheet metal 11 to be tested with the plug cover 14 installed is installed on the test platform 2, it is clamped by the positioning clamp 12 so that the sheet metal 11 is close to the surface of the test platform 2, and then the water-saving valve is opened, and the water in the water column 3 is continuously injected into the water reservoir 6. When the injection is completed, there will be some air between the water reservoir 6 and the sheet metal 11 to be tested; at this time, as shown in FIG. Figure 4 and Figure 5 As shown, the test bench 2 is turned 180 degrees around the hinge 8. After turning, the air between the water reservoir 6 and the sheet metal 11 to be tested will flow into the bottom of the water reservoir 6. Then, the exhaust valve 7 is opened. Under the continuous supply of water pressure, the air is exhausted, and the valve is closed. Finally, the test bench 2 is turned back to the original position as shown in FIG. Figure 2 and Figure 3 In the state shown, under a certain water pressure mode, water contacts the test surface of the plugging cover 14 on the surface of the sheet metal 11, and the sealing and water seepage of the plugging cover 14 on the surface of the sheet metal 11 is observed in real time to realize the waterproof test.
