Detailed Description
The invention is described in further detail below with reference to the following detailed description and accompanying drawings: referring to fig. 1 to 3, a kettle assembly airtightness detection tool comprises a base 1, a water tank 2 is arranged on the base 1, a lifting mechanism 3 is arranged on one side of the base 1, a support plate 100 lifted by the lifting mechanism is arranged on an output end of the lifting mechanism 3, a sealing mechanism 4 is fixedly arranged on the support plate 100, the sealing mechanism 4 comprises a bottom plate 40, a stand column 41 arranged on the bottom plate 40, a partition plate 42 fixedly arranged at one end of the stand column 41, a through hole 43 matched with the shape of the kettle assembly is arranged on the partition plate 42, a clamping device 44 for clamping the kettle assembly, a first plugging device 101 for plugging an opening of the kettle assembly and a second plugging device 102 for plugging an exhaust port and a liquid discharge port of the kettle assembly are arranged on the sealing mechanism 4;
the first blocking device 101 comprises a first cylinder 101a and a gland 101b pushed by the first cylinder, an air pipe is connected to the gland 101b, one end of the air pipe is connected with a pneumatic pump to supply compressed air into the kettle assembly, a pressure gauge 200 is arranged on the portion of the air pipe between the pneumatic pump and the gland, and the second blocking device 102 comprises a second cylinder 102a and a plug 102b pushed by the second cylinder.
In the above technical solution, the water bottle assembly is installed into the sealing mechanism along the through hole 43 on the partition plate 42 of the sealing mechanism 4, and at this time, the partition plate 42 is set to have its upper end face located below the welding position of the water bottle assembly; the kettle assembly is fixed through the clamping device 44, the opening of the kettle assembly is plugged through the first plugging device, and the exhaust port and the liquid outlet of the kettle assembly are plugged through the second plugging device;
then pumping compressed air into the kettle assembly along the air pipe through an external pneumatic pump, and closing the air pump after a certain amount of compressed air is injected; at this time, the entire sealing mechanism 4 is immersed in the water tank 2 by the elevating mechanism 3.
Because the welding position of position at the kettle assembly is revealed usually, and, the kettle assembly is because the volume is great for water level is darker in the water tank, consequently when the crack is less, because the light reflection refraction problem of water tank bottom, the little bubble of welding seam department is hardly observed by the detection personnel, consequently, has set up the division board in this application, and the division board is equivalent to and has provided the background board for when observing the bubble, so that receive the interference of water tank bottom during the observation. Furthermore, a plurality of mounting seats 45 are arranged outside the through holes 43 at intervals, and a light source (not shown in the drawing) is fixedly arranged in the mounting seats 45 and provided with a light beam projected to the welding position of the kettle assembly, so that the micro bubbles can be more clearly shown through the light beam, and the probability of false detection of detection personnel is further reduced. Further, whether or not there is an air leak can be determined by the magnitude of the pressure change in the pressure gauge 200.
Further, the upright 41 can be lifted. And then the position of division board is adjusted according to the kettle assembly of different models for division board up end is located kettle assembly welding position below all the time.
Specifically, the clamping device 44 includes a flexible pressing block 44a disposed outside the plug 102b of the second cylinder and a flexible positioning block 44b protruding from the bottom plate 40.
