Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0024] Example

[0025] Combination Figures 1 to 3 This embodiment provides an airtightness testing device for a filter, including a tooling base plate 1, a first sealing mechanism 2, and a second sealing mechanism 3. The tooling base plate 1 is provided with a limiting seat 4 for placing and limiting the filter A. The first sealing mechanism 2 is disposed on one side of the filter A, and the second sealing mechanism 3 is disposed on the other side of the filter A.

[0026] The first sealing mechanism 2 includes a first cylinder 5 and a first plug 6 connected to the first cylinder 5. The first plug 6 is used to seal an oil pipe B of the filter A. The second sealing mechanism 3 includes a second cylinder 7 and a second plug 8 connected to the second cylinder 7. The second plug 8 is connected to an air pipe connector C that communicates with another oil pipe B of the filter A. After air pressure is introduced to the air pipe connector C, the filter A, placed in the water tank, is further subjected to a water test to check the airtightness of the filter.

[0027] The airtightness testing device for filters described above, through the cooperation of the first sealing mechanism 2 and the second sealing mechanism 3, uses a cylinder to drive the alignment and sealing of the oil pipe B of filter A, avoiding the tedious steps of traditional manual pipe insertion and greatly improving the testing efficiency.

[0028] The first plug 6 seals one oil pipe B, and the second plug 8 connects to the air pipe connector C and is inserted to connect to another oil pipe B. This allows for stable and precise air pressure to be introduced into the filter A. In conjunction with the water test, the airtightness of the filter can be effectively tested, thereby ensuring the reliability and consistency of the test results.

[0029] The limiting seat 4 secures and fixes filter A, ensuring its stability and reliability during testing. This reduces errors caused by human operation, helps guarantee product quality and shorten the production cycle. It is also compatible with different specifications of filter A, providing a versatile airtightness test for the filter A production line. This eliminates the direct involvement of workers in high-pressure air pipe insertion and sealing tests, reducing their workload and avoiding potential safety risks caused by improper operation.

[0030] In this embodiment, the first cylinder 5 is located on the left side of the limiting seat 4, and the first plug 6 is directly opposite to the oil pipe B connected to the filter A. During the testing process, the first cylinder 5 drives the first plug 6 to move in a straight line, so that it firmly seals the oil pipe B interface of the filter A, ensuring the sealing performance of the airtightness test, while reducing the testing error caused by positional deviation, and further improving the accuracy and reliability of the test. Preferably, the first plug 6 is configured as a non-porous plug structure to achieve the sealing purpose after being pushed and aligned.

[0031] In this embodiment, the second cylinder 7 is located on the right side of the limiting seat 4, and the second plug 8 is directly opposite to the other oil pipe B connected to the filter A. During airtightness testing, the second cylinder 7 drives the second plug 8 to move, precisely connecting it to the interface of the oil pipe B, and introducing air pressure into the filter A through the air pipe connector C on it, realizing the automated operation of the airtightness test, ensuring the sealing and stability of the testing process, and improving the operating efficiency and testing accuracy of the device. Preferably, the second plug 8 is configured as a perforated plug structure, which is used to connect the air pipe connector C to the associated oil pipe B.

[0032] In the above description, the first cylinder 5 and its first plug 6 are used to directly seal the oil pipe B on one side to achieve a sealing effect. Correspondingly, the second cylinder 7 and its second plug 8, after being aligned with the oil pipe B on one side, allow the air pipe connector C equipped with the second plug 8 to further connect to the interior of the filter A through the oil pipe B, thereby inputting high-pressure gas. This allows for a water test after the entire device and filter A are immersed in a water tank, thus providing a more intuitive and efficient assessment of the product's airtightness.

[0033] like Figure 2 and Figure 3 As shown, in this embodiment, the limiting seat 4 is provided with a first baffle 9 for lateral limiting, a second baffle 10 for front limiting, and a fixing pin 11 for the filter seat of filter A. Specifically, the first baffle 9 is disposed on the side of the limiting seat 4 to laterally limit filter A and prevent it from lateral displacement during testing. The second baffle 10 is disposed on the front of the limiting seat 4 to frontally limit filter A and prevent filter A from moving back and forth due to cylinder drive or air pressure. The fixing pin 11 is disposed on the filter seat portion of the limiting seat 4 to stabilize the installation position of filter A and, together with the first baffle 9 and the second baffle 10, ensures the accurate positioning of filter A during testing.

[0034] The first cylinder 5 and the second cylinder 7 are both equipped with a fixing plate 12 that is assembled and connected to the tooling base plate 1. Thus, the fixing plate 12 provides a stable support structure, ensuring that the cylinders remain fixed during operation and will not shift due to vibration or external forces, thereby guaranteeing the reliability and durability of the device. Preferably, the fixing plate 12 has an upper mounting position and a lower mounting position to adapt to the position of the oil pipe B of the filter A, allowing the cylinder to push its plug to quickly and flexibly connect to the corresponding oil pipe B.

[0035] The tooling base plate 1 has a reinforcing side plate 13 that is fixedly connected to the fixing plate 12. Obviously, by being fixedly connected to the fixing plate 12, the reinforcing side plate 13 effectively improves the rigidity and load-bearing capacity of the tooling base plate 1, prevents the vibration or lateral force generated by the cylinder from affecting the stability of the device, and ensures that the cylinder runs more smoothly.

[0036] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions that fall within the scope of this utility model's concept are protected by this utility model.
