Furthermore, the pushed cabin pressure regulator will enter the inside of the collection box 20, so that the collection box 20 can collect the cabin pressure regulator.

[0035] Working principle: First, place the completed cockpit pressure regulator on the top of the workbench 1, and then start the first hydraulic rod 3. The output end of the first hydraulic rod 3 drives the transmission plate 4 to move, so that the transmission plate 4 drives the sliding block 5 to slide outside the guide rail 10. Furthermore, when the sliding block 5 moves, it drives the moving column 6 to move, and then when the moving column 6 moves, it drives the moving plate 7 to move. When the moving plate 7 moves to the appropriate position, start the second hydraulic rod 8. The output end of the second hydraulic rod 8 drives the clamping plate 9 to move, so that the clamping plate 9 clamps and fixes the cockpit pressure regulator. Then, start the turntable 11, and the turntable 11 drives the rotating plate 12 to rotate. Thus, when the rotating plate 12 rotates to the appropriate position, start the third hydraulic rod 13. The output end of the third hydraulic rod 13 drives the power plate 14 to move, so that the power plate 14 drives the tester 15 to move, and then the tester 15 detects the clamped and fixed cockpit pressure regulator.

[0036] After the detection of the cockpit pressure regulator is completed, start the fourth hydraulic rod 17. The output end of the fourth hydraulic rod 17 drives the pushing plate 18 to move, so that the pushing plate 18 pushes the cockpit pressure regulator placed on the top of the workbench 1, and then the pushing plate 18 pushes the cockpit pressure regulator into the interior of the collection box 20, and the collection box 20 collects it.
