[0044] The working principle of the special tooling for thin-walled jacket sealing detection provided by the utility model is as follows:

[0045] A sealing detection device 10 with a second docking plate 9 is installed on the detection table 11, and then the fixed plate 7 with the first telescopic rod 5 is installed on the top of the detection table 11 at a position corresponding to the position of the second docking plate 9, and a first docking plate 8 is installed at the telescopic end of the first telescopic rod 5 through a rotating component 6. The interiors of the first docking plate 8 and the second docking plate 9 are in contact with the inlet and outlet of the sealing plate 30 and the thin-walled jacket to improve the sealing performance, and the rotating component 6 is connected to the pressure supply pipe 28, and the high-pressure gas can be injected into the thin-walled jacket for testing through the boosting component 12. In actual use, the thin-walled jacket is first placed between the first docking plate 8 and the second docking plate 9, and then the first telescopic rod 5 is started to push the first docking plate 8 to contact one end of the thin-walled jacket, and at the same time, the thin-walled jacket is clamped with the second docking plate 9, and then the first valve 16 is opened and the boosting component 12 is started to extract the high-pressure gas inside the gas tank 18, and then the high-pressure gas is extracted through the pressure supply pipe 28 and the rotating component. Component 6 is injected into the interior of the thin-walled jacket. If the gas needs to be colored, the second valve 20 can be opened and the pigment in the pigment tank 19 will enter the interior of the thin-walled jacket along with the high-pressure gas as the airflow flows. In this process, the first one-way valve 15, the second one-way valve 21 and the third one-way valve 27 can prevent the high-pressure gas and pigment from flowing back, and the pressure sensor 31 in the second docking plate 9 records the pressure inside the thin-walled jacket. When the corresponding value is reached, the gas supply is stopped. At the same time, the first valve 16, the second valve 20 and the third valve 26 are closed synchronously, and the booster component 12 will also stop working. The pressure sensor 31 can display the detected data through the sealing detection device 10. If a leak occurs, the colored gas will be discharged and can be observed in time. After the monitoring is completed, you only need to retract the first telescopic rod 5 to release the restriction on the thin-walled jacket, and then remove the thin-walled jacket from between the first docking plate 8 and the second docking plate 9.

[0046] Compared with related technologies, the special tooling for thin-walled jacket sealing detection provided by the utility model has the following beneficial effects:

[0047] In order to improve the efficiency of sealing detection of thin-walled jackets, a sealing detection device 10 with a second docking plate 9 is installed on the detection platform 11, and then the fixed plate 7 with the first telescopic rod 5 is installed at the top of the detection platform 11 and the position corresponding to the position of the second docking plate 9.
