[0043] Working principle of the present invention:

[0044] First, place the flow meter housing that needs to be subjected to the sealing pressure test in the charging trough 51, and then control the motor 8 to work, so that the motor 8 drives the residual gear 1 9 fixedly connected to its output shaft to rotate. At this time, the residual gear 1 9 will rotate with the large gear 2 511, so that the large gear 2 511 drives the vertical rod 510 fixedly connected to it to rotate, and the vertical rod 510 will drive the active cone wheel 2 512 fixedly connected to it to rotate when rotating, so that the active cone wheel 2 512 drives the driven cone wheel 2 513 meshing with it to rotate, and the driven cone wheel 2 513 will drive the rotating rod 514 fixedly connected to it to rotate when rotating, so that the rotating rod 514 drives The driving wheel 1 516 fixedly connected thereto rotates, and when the driving wheel 1 516 rotates, the copper drum belt 1 517 drives the driven wheel 1 518 to rotate, so that the driven wheel 1 518 drives the driving shaft 519 fixedly connected thereto to rotate, and when the driving shaft 519 rotates, it drives the threaded rod 3 54 fixedly connected thereto to rotate, so that the threaded rod 3 54 drives the threaded block 55 threadedly connected thereto to move, and when the threaded block 55 moves, it drives the push plate 56 fixedly connected thereto to move synchronously, so that the push plate 56 pushes the flow meter housing, so that the flow meter housing closest to the discharge chute 52 falls onto the stabilizing table 413 through the discharge chute 52;

[0045] When the residual gear 19 is disengaged from the large gear 2 511, it will mesh with the large gear 10, so that the large gear 10 drives the vertical shaft 11 fixedly connected to it to rotate, and when the vertical shaft 11 rotates, it will drive the rotating frame 3 fixedly connected to it to rotate, so that the box body 41 at the loading area of ​​the rotating frame 3 is transported to the sealing area. At this time, the cross groove rod 62 will be connected to the spline rod 46 through the cross groove, and the residual gear 19 is disengaged from the large gear 10, so that the residual gear 19 is meshed with the large gear 2 511, thereby causing the vertical rod 510 to rotate. When the vertical rod 510 rotates, it will drive the active bevel wheel 3 69 fixedly connected to it to rotate, so that the active bevel wheel 3 69 drives the driven bevel wheel 3 68 meshed with it to rotate, and when the driven bevel wheel 3 68 rotates, it will drive the connecting rod 66 fixedly connected to it to rotate, so that the connecting rod 66 drives the active wheel 2 65 fixedly connected to it to rotate, and when the active wheel 2 65 rotates, it will pass through the belt The belt 2 64 drives the driven wheel 2 63 to rotate, so that the driven wheel 2 63 drives the transverse groove rod 62 fixedly connected thereto to rotate. When the transverse groove rod 62 rotates, it drives the spline rod 46 to rotate through the transverse groove, so that the spline rod 46 drives the active cone wheel 1 45 fixedly connected thereto to rotate. When the active cone wheel 1 45 rotates, it drives the driven cone wheel 1 44 meshed therewith to rotate, so that the driven cone wheel 1 44 drives the connecting rod 43 fixedly connected thereto to rotate. When the connecting rod 43 rotates, it drives the threaded rod 1 47 and the threaded rod 2 48 fixedly connected thereto to rotate, so that the threaded rod 1 47 and the threaded rod 2 48 respectively drive the threaded seat 49 threadedly connected thereto to move toward each other, and when the threaded seat 49 moves, it drives the movable plate 410 fixedly connected thereto to move synchronously, so that the movable plate 410 drives the sealing member 411 fixedly connected thereto to move synchronously, and when the sealing member 411 moves, it seals both ends of the flow meter housing;

[0046] Since the specifications of the flowmeter housing are consistent, the spline rod 46 can be controlled to rotate an integer number of circles to control the seal 411 to seal the flowmeter housing. When the sealing is completed, the residual gear 9 will disengage from the large gear 2 511 and mesh with the large gear 10, thereby transporting the flowmeter housing in the sealing area to the detection area, and making the residual gear 9 mesh with the large gear 2 511 again. At this time, the connecting rod 66 will drive the active wheel 3 718 fixedly connected thereto to rotate, so that the active wheel 3 718 drives the driven wheel 3 716 to rotate through the belt 3 717. When the driven wheel 3 716 rotates, it will drive the cross bar 714 fixedly connected thereto to rotate, so that the cross bar 714 drives the residual gear 2 715 fixedly connected thereto to rotate. At this time, the residual gear 2 715 will mesh with the small gear 79, so that the small gear 79 drives the connecting shaft 78 fixedly connected thereto to rotate, and when the connecting shaft 78 rotates, it will drive the threaded rod 4 72 fixedly connected thereto to rotate. , thereby the threaded rod four 72 drives the threaded plate 73 threadedly connected thereto to move, and the threaded plate 73 will drive the fixed plate 74 fixedly connected thereto to move synchronously when moving, so that the fixed plate 74 drives the inflatable member 75 fixedly connected thereto to move, and then the inflatable member 75 is tightly combined with the ventilation groove 412. At this time, the control motor 8 stops working, and the air pump 13 is used to pressurize the inside of the flow meter housing. After the pressurization is completed, observe whether the pressure gauge 14 has any changes to determine the sealing effect of the flow meter housing, and then control the motor 8 to work again. At this time, the residual gear two 715 will mesh with the small gear 79, so that the threaded rod four 72 is reversed under the action of the belt 710, so as to control the inflatable member 75 to move to the original position for the next operation. At this time, the residual gear one 9 will disengage from the large gear two 511 and begin to mesh with the large gear one 10, thereby transporting the flow meter housing to the unloading area. At this time, the control spline rod 46 is rotated to take out the flow meter housing.
