[0037] In the preferred embodiment, the clamping support frame 205 is further hingedly provided with a clamping cylinder 209, and the telescopic shaft of the clamping cylinder 209 is hingedly connected with the upper part of the rotating tray 203.

[0038] The clamping cylinder 209 drives the rotating tray 203 to rotate on the clamping support frame 205.

[0039] The air filter clamping device of the embodiment mainly comprises a front end support frame 105 and a clamping support frame 205, which is used for realizing efficient clamping of the filter in performance test, effectively solving the problem of frequent replacement of test fixtures caused by size difference of the filter, and improving clamping precision and test accuracy.

[0040] The front end pipeline 1 of the filter is connected with the front end support frame 105 in a sliding manner. The front end guide rail 106 is carefully arranged on the front end support frame 105, and the lower surface of the front end pipeline 101 is smoothly matched with the front end sliding block 107, so as to ensure the stable movement and accurate positioning of the front end pipeline 1. One end or both ends of the front end guide rail 106 are provided with the front end limiting block 108, so as to accurately define the sliding range of the front end pipeline 1, prevent overtravel, and ensure the safety and stability of operation. For example, in the actual clamping process, the front end sliding block 107 stably slides along the front end guide rail 106 until it is in contact with the front end limiting block 108, so that the front end pipeline 1 is accurately positioned.

[0041] The clamping pipeline 2 is also connected with the clamping support frame 205 in a sliding manner, and can be axially rotated on the clamping support frame 205. The lower surface of the clamping pipeline 201 is firmly connected with the rotating tray 203, the lower surface of the clamping sliding block 207 is connected with the clamping guide rail 206 on the clamping support frame 205 through the clamping sliding block 207, and one end or both ends of the clamping guide rail 206 are provided with the clamping limiting block 208.

[0042] The front end pipeline 1 and the clamping pipeline 2 are stably connected through the front end buckle 102, the tail of the clamping pipeline 2 is reliably connected with the rear end pipeline 3 through the single-head buckle 202, and the front end buckle 102 and the single-head buckle 202 are consistent in structure. Taking the front end buckle 102 as an example, a plurality of concave clamping grooves 1021 are distributed on the end surface of the front end pipeline 1, and a plurality of convex clamping blocks 1022 are correspondingly arranged on the clamping pipeline 2. The concave clamping groove 1021 and the convex clamping block 1022 are accurately provided with a clamping hole 1023. One side of the front end buckle 102 is provided with a front end cylinder 103. When the concave clamping groove 1021 and the convex clamping block 1022 are accurately matched to make the two clamping holes 1023 coaxial, the shaft body of the front end cylinder 103 smoothly passes through the clamping hole 1023, strongly locks the front end buckle 102, ensures the close and stable connection, prevents the filter from loosening during testing, and ensures the reliability of the test data.

[0043] One end of the front end pipeline 1 is provided with the front end flange 104, and the clamping pipeline 2 is symmetrically provided with the clamping flange 204 at both ends.

[0044] The end of front-end pipe 101 cleverly connects to flexible connecting pipe 110 via reducer 109. This design significantly enhances the device's adaptability to varying filter specifications and complex testing environments. Reducer 109 allows for flexible diameter adjustment to meet varying flow requirements. Flexible connecting pipe 110 effectively buffers vibration and compensates for installation errors, ensuring a secure and reliable connection and smooth airflow, comprehensively enhancing the device's practicality and stability.

[0047] S1. First, slide the front-end pipe 101 and the clamping pipe 201 horizontally. Then, use the clamping cylinder 209 to adjust the clamping pipe 201 from the horizontal direction to the vertical direction. After the filter is installed, use the clamping cylinder 209 to adjust the clamping pipe 201 from the vertical direction to the horizontal direction.

[0048] S2, then slide the front end pipe 101 and the clamping pipe 201 in the opposite horizontal direction and make them contact with the front end limit block 108 and the clamping limit block 208 respectively;

[0049] S3. The shaft of the front cylinder 103 is locked with the front buckle 102 and the single-end buckle 202 in sequence. At this time, the front flange 104 and the clamping flange 204 are in contact and aligned. The shaft of the rear cylinder 303 is locked with the rear buckle 302 and the single-end buckle 202 in sequence. At this time, the rear flange 304 and the clamping flange 204 are in contact and aligned.

[0050] S4. Fill the airtight devices 210 clamping the two ends of the pipe 201 with air to form sealed end faces.

[0051] How to use the air filter clamping device

[0052] This method of use works closely with the clamping device of Example 1, providing a precise and efficient process for the clamping operation in the square air filter performance test, ensuring accurate installation and stable testing of the filter, and effectively improving test efficiency and data quality.

[0053] 1. Preparation and preliminary adjustment before clamping

[0054] At the beginning of the operation, the front-end pipe 101 and the clamping pipe 201 are slid horizontally along their respective guide rails to ensure that all components of the device are in an initial flexible state, laying the foundation for subsequent precise clamping of the filter.

[0055] Subsequently, the clamping cylinder 209 drives the clamping pipeline 201 to smoothly adjust from horizontal to vertical around the axis of the rotating tray 203. During this process, the extension shaft of the clamping cylinder 209 precisely exerts force at the hinge on the upper part of the rotating tray 203, ensuring smooth rotation and precise angle of the clamping pipeline 201, creating favorable space conditions for filter installation. After the filter is accurately installed at the predetermined position, the clamping cylinder 209 again precisely acts to drive the clamping pipeline 201 to reverse from vertical to horizontal, ensuring correct posture and stable position of the filter, preparing for subsequent connection operations.

[0056] 2. Clamping position calibration and limiting: After the above adjustment, the front-end pipeline 101 and the clamping pipeline 201 are pushed to slide in opposite directions until they are in close contact with the front-end limiting block 108 and the clamping limiting block 208, respectively. Through the precise limiting of the limiting block, the positional deviation during clamping is effectively eliminated, ensuring the accurate alignment of the front-end pipeline 1 and the clamping pipeline 2, providing a stable and reliable reference for subsequent buckle and flange connection, further improving the accuracy of the filter clamping position, and ensuring the consistency of the test environment.

[0057] 3. Buckle and flange locking operation

[0058] The front-end cylinder 103 is sequentially started, and its shaft body precisely passes through the coaxial buckle hole 1023 of the front-end buckle 102 and the single-head buckle 202, applies stable and moderate pressure to lock the buckle, makes the front-end flange 104 tightly fit and align with the clamping flange 204, builds a stable connection structure, and ensures the stable and reliable mechanical performance of the filter during testing.

[0059] The rear-end cylinder 303 works synchronously, and its shaft body precisely cooperates with the rear-end buckle 302 and the single-head buckle 202 to stably lock the rear-end flange 304 and the clamping flange 204, and comprehensively enhances the reliability of the filter connection with the front and rear pipelines, ensuring stable airflow and constant pressure during testing, and laying a solid foundation for accurately obtaining filter performance data.

[0060] 4. Air-tight end face construction and test environment optimization: Finally, appropriate amount of air is uniformly filled into the air-tight device 210 at both ends of the clamping pipeline 201, so that the air-tight device is moderately expanded and tightly fills the gap between the flanges to form a reliable sealed end face. This sealed end face effectively prevents external gas interference, ensures that the filter test is carried out in a stable airtight environment, significantly improves the accuracy and reliability of the test results, and provides solid data support for filter performance evaluation.
