Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
In fig. 1 to fig. 3, an end cover airtightness detection apparatus includes a pressure cylinder air source assembly, three pressure cylinders 20, three water tanks 30, three adjustable positioning and pressing assemblies, and a pedestal cabinet 50, which are sequentially arranged from top to bottom. The cylinder air supply assembly is connected to the cylinder 20 by a connecting plate 21. A stepped ram 22 is provided at the bottom end of the booster cylinder 20. The ram 22 is pressed down and crimped at the center of the end cap 100. The positioning and pressing assembly is arranged at the bottom end of the water tank 30, a workbench 40 is arranged at the top end of the support cabinet 50, and the water tank 30 is connected with the workbench 40. The end cover 100 is tightly pressed on the positioning pressing component by the pressure cylinder air source component, and the pressure cylinder air source component displays the detection state.
The positioning and pressing assembly comprises a positioning member 66, an upper positioning plate 63, a lower positioning plate 62 and 4 positioning screws 64. The positioning member 66 is fixed at the top end of the upper positioning plate 63, and the upper positioning plate 63 and the lower positioning plate 62 are connected by a positioning screw 64. A spring 65 is inserted and pressed on a positioning screw 64 between the lower positioning plate 62 and the upper positioning plate 63. The end cap 100 abuts the positioning member 66 via the packing 67.
A supporting plate 61 is fixed to the bottom end of the water tank 30. The support plate 61 is fixed at the top end of the table 40. The water tank 30 is provided at its rear surface with a water pipe connector 31.
The air source assembly of the pressure cylinder comprises a housing 10, and a digital display panel 11 and an air source main switch 15 are arranged at the top end of the housing 10. The end face of the housing 10 in the length direction is of a trapezoid structure, an air source part 12, a state display part 13 and an air source button 14 are sequentially arranged on one side face of the housing 10 in the length direction, and the air source part 12 is adjacent to the digital display panel 11.
The worktable 40 is provided with a test button 42 and an emergency stop button 41, and the emergency stop button 42 is provided at both ends of the worktable 40. The number of test buttons 42 is the same as the number of pressurizing cylinders 20, and the number of pressurizing cylinders 20 is the same as the number of water tanks 30.
A sealed test gas source 51 and a power switch 52 are disposed at one end of the holder cabinet 50. The four corners of the bottom end of the support cabinet 50 are provided with 4 adjustable rollers 53. The roller 53 can be adjusted to be lifted up to serve as a supporting leg and adjusted to be lowered down to serve as a moving wheel.
The whole mode is semi-automatic. The air tightness detection device is divided into three groups of air tightness detection modules, and each module is independently controlled.

Product locator 66 is located in the filled reservoir. When the pressure cylinder 20 is not pressed down, the positioning piece 66 is higher than the water surface, and after the end cover is manually placed into the positioning piece 66, the two parts are openedThe test button 42 is manually pressed, the pressure cylinder is pressed down, the end cap and the positioning member 66 are submerged, the cavity of the end cap is filled with air, and the pressure cylinder is kept pressed down for 30S. The digital display panel 11 displays whether the air tightness of the workpiece is good or not, and whether bubbles exist in water or not is observed. And simultaneously carrying out the next group of air tightness detection actions.
The above is only a specific application example of the present invention, and does not constitute any limitation to the protection scope of the present invention.
