The most again, the external seal end 144 of outer side seal assembly 140 is under the driving of the second drive division 142
Slide to determinand, when external seal end 144 is inconsistent with the outside of determinand, continues phase front and slide one
Segment distance so that interior sealed end 127a is inconsistent with the inner side of determinand, thus forms sealing, now institute
State control system and read the pressure information of described pressure sensor feedback, thus close to described black box
Seal pressure is controlled and regulates, until the external seal end 144 of outer side seal assembly 140 and inner seal
The interior sealed end 127a of assembly 127 is sufficiently sealed by determinand, the most whole cunning for air tightness test
Dynamic resetting-mechanism 100 is in the test mode such as Fig. 6, Fig. 7, Figure 11, Figure 12 and Figure 21；
4. last, by being inflated inside the air intake assembly 143a sealing to determinand, air-tightness simultaneously
Mechanism for testing starts determinand is carried out air tightness test, after air tightness test completes, and the second drive division
142 traction external seal ends 144 retreat, now under the effect of reset assembly 123a, 134a, and whole use
Slip resetting-mechanism 100 in air tightness test is returned to the reset such as Fig. 5, Fig. 9, Figure 10 and Figure 20
State, then hold down assembly 130 described compressed part rise under the driving of the first drive division 132 at the beginning of
Beginning position, described driver drives carrier assembly 120 to loading and unloading station as shown in fig. 13 that, automation
Loading and unloading manipulator arm takes off testing rear determinand on the second load plate 124 of carrier assembly 120,
Bracing frame 110 is pushed internal etc. to be tested after changing next determinand.
