The installation cavity 13 is installed at the front and rear ends above the base plate 1. A servo motor 14 is installed on one side of the top of the installation cavity 13. A first bevel gear 15 is installed on one side above the inside of the installation cavity 13. The output end of the servo motor 14 is connected to one end of the first bevel gear 15. The second bevel gear 16 is meshed with the side below the first bevel gear 15. A threaded rod 17 is installed at one end of the second bevel gear 16. The outer wall of the threaded rod 17 is provided with a threaded sleeve 18. The outer wall of the threaded sleeve 18 is fixedly installed with an active cavity 19. The active cavity 1 A clamping plate 20 is installed at one end of 9. The clamping plate 20 is designed to be arc-shaped. The two clamping plates 20 cooperate with each other. When in use, the filter element is placed inside the sealing groove 2, and then the servo motor 14 is started to drive the first bevel gear 15 to rotate. Since the first bevel gear 15 and the second bevel gear 16 are engaged with each other, the second bevel gear 16 is used to drive the threaded rod 17 to rotate, and then drive the threaded sleeve 18 to move. Therefore, under the limit of the limit groove 21 and the limit block 22, the threaded sleeve 18 is used to drive the active cavity 19 to move, and the active cavity 19 is used to drive the clamping plate 20 to move.

[0022] Working principle: The staff first places the filter element inside the sealing groove 2, and then starts the servo motor 14 to drive the first bevel gear 15 to rotate. Since the first bevel gear 15 and the second bevel gear 16 are meshed with each other, the second bevel gear 16 is used to drive the threaded rod 17 to rotate, and then the threaded sleeve 18 is driven to move. Therefore, under the limit of the limit groove 21 and the limit block 22, the threaded sleeve 18 is used to drive the movable cavity 19 to move, and the movable cavity 19 is used to drive the clamping plate 20 to move, and the two clamping plates 20 are used to clamp the filter element. The core is clamped and positioned, and then the cylinder 7 is started. Under the guidance of the guide rod 11 and the guide sleeve 12, the cylinder 7 is used to drive the mounting plate 8 and the sealing gasket 9 to move downward, and the sealing gasket 9 is used to seal the filter element. Then the air compressor 5 is started, and the filter element is tested with the cooperation of the delivery hose 6. The pressure inside the filter element can be measured by the pressure sensor 10. After the test is completed, the cylinder 7 is started to drive the mounting plate 8 to move upward, and then the servo motor 14 is started to reverse and drive the clamping plate 20 to move outward. At this time, the filter element can be removed.
