Description

Technical Field

[0001] The utility model relates to the technical field of airtight detection equipment, in particular to an airtight detection tool with a built-in fine filter. Background Art

[0002] Filters are mainly used in automobiles, air compressors and other equipment to filter air or oil, etc. Since filters are used for air and oil filtration, the filter element is an important functional component of the filter. The filter elements used for filters include built-in fine filters and external fine filters, so there are usually very high requirements for their air tightness.

[0003] When conducting air tightness test on the built-in fine filter, the product to be tested needs to be placed on the testing tooling, then the air outlet of the product to be tested is blocked, and air is inflated into the product to be tested through the air inlet so that the interior of the product to be tested can be filled with the required air pressure. At this time, press the test button, and the testing equipment executes the test procedure to complete the test. After the test is completed, the air outlet needs to be opened to release the air pressure and take out the product after the test is completed.

[0004] In the prior art, sealing of the air inlet and outlet of a product is mostly done manually, resulting in low detection efficiency. Utility Model Content

[0005] The utility model aims to provide a built-in fine filter airtight detection tooling to solve the problem that the prior art mostly uses manual labor to seal the air inlet and outlet ends of products, resulting in low detection efficiency.

[0006] In order to achieve the above-mentioned purpose, the basic scheme of the utility model is as follows: a built-in fine filter airtight detection tooling, including a base and a plurality of detection units, and the plurality of detection units are installed on the base, and the detection unit includes a rotary downward pressure cylinder, a top plate, two air inlet end mechanisms, two air outlet end mechanisms and two positioning mechanisms, and the top plate is installed on the top of the rotary downward pressure cylinder, and the two air inlet end mechanisms are respectively installed at the two ends of the top plate, and the two air outlet end mechanisms are respectively installed on the bases on both sides of the rotary downward pressure cylinder, and the two air outlet end mechanisms are located directly below the end point of the downward pressure stroke of the air inlet end mechanism, and the two positioning mechanisms are respectively located on the sides of the two air outlet end mechanisms, and the positioning mechanism is installed on the base.

[0007] Furthermore, the detection unit also includes a return mechanism, which includes a limit plate and an elastic return member. The limit plate is slidably connected to the air outlet end mechanism, and the elastic return member is installed between the limit plate and the base for automatic upward return of the limit plate.

[0008] Furthermore, mounting connecting plates are provided at both ends of the base.

[0009] Furthermore, three detection units are provided, and the three detection units are installed on the base at equal distances.

[0010] Furthermore, the base is provided with a hollow weight-reducing hole, and the hollow weight-reducing hole is located between every two adjacent detection units.

[0011] The beneficial effects of this scheme are as follows: (1) the product to be tested is placed on the air outlet mechanism, and the product to be tested is positioned by the positioning tooling, and then the rotating downward pressure cylinder is started, and the rotating downward pressure cylinder drives the top plate to rotate, so that the air inlet mechanism rotates to the top of the air outlet, and the rotating downward pressure cylinder drives the air inlet mechanism downward through the top plate, thereby pressing the product to be tested, and sealing the air outlet and air inlet ends of the product to be tested, and inflating the product to be tested through the air inlet end so that the inside of the product to be tested can be filled with the required air pressure. At this time, the test button is pressed, and the testing equipment executes the test program to complete the test. After the test is completed, the rotating downward pressure cylinder drives the air inlet mechanism to lift up, thereby releasing the restriction on the product and taking out the product. This scheme can quickly complete the sealing of the air inlet and air outlet ends of the product to be tested, thereby improving the detection efficiency.

[0012] (2) Under the action of the return mechanism, when the air inlet end mechanism is lifted, the top of the product loses the restriction of the air inlet end mechanism, and the return mechanism bounces the product upward, making it easier to take out the product.

[0013] (3) This solution has multiple inspection stations on a base, which can inspect multiple products at the same time, thereby improving inspection efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
