Detailed Description
The technical solution of the present invention will be further explained with reference to the accompanying drawings.
Referring to fig. 1-2, the above-mentioned gear cover air tightness testing device includes a water tank 1, a guide post 2 fixed in the water tank 1, a mounting plate 3 capable of lifting along the length extending direction of the guide post 2 and sleeved on the guide post 2, an elastic member 4 sleeved on the guide post 2 and located below the mounting plate 3, and a limiting member 11 fixedly connected to the guide post 2 and located above the mounting plate 3.
In this embodiment, as shown in fig. 2, the lower surface of the mounting plate 3 is provided with a guide sleeve 12 sleeved on the guide post 2, the elastic member 4 is a pressure spring, the upper end of the pressure spring is fixedly connected to the guide sleeve 12, and the lower end of the pressure spring is fixedly connected to the bottom plate of the water tank 1.
In the present embodiment, four guide posts 2 are respectively inserted into four corners of the rectangular mounting plate 3. The four guide posts 2 are parallel to each other, and the axes of the four guide posts extend along the vertical direction. The mounting plate 3 is parallel to the horizontal direction, and the elastic member 4 is used for providing an elastic restoring force for driving the mounting plate 3 to reset upwards, so that the mounting plate 3 can be prevented from popping up the guide post 2 upwards by arranging the limiting part 11. The limiting piece 11 is arranged at the top end of the guide post 2.
Above-mentioned gear cover gas tightness testing arrangement still including locate in water tank 1 and be used for carrying out spacing stop gear to mounting panel 3, locate on mounting panel 3 and be used for bearing the profile modeling frock 5 of gear cover 13, locate on mounting panel 3 and be used for compressing tightly the hold-down mechanism of gear cover 13, with the suction nozzle 6 of gear cover 13 intercommunication.
The limiting mechanism comprises a hook member 7, one end of which is rotatably connected in the water tank 1 and the other end of which is used for hooking the mounting plate 3. The mounting plate 3 is provided with a through hole 8 which is hooked by the hook 7.
In this embodiment, the hook member 7 has an inverted L-shape, and the lower end of the hook member 7 is a rotating end and the upper end is a hooking end. The axis of rotation of the hook member 7 extends in a horizontal direction, and the plane of rotation of the hook member 7 is perpendicular to the mounting plate 3. The hook member 7 is located below the liquid level for hooking the mounting plate 3 below the liquid level so that the gear cover 13 can be submerged below the liquid level. When the hook member 7 of the inverted L-shaped hooks the mounting plate 3, the transverse edge with the hook is positioned above the mounting plate 3 so as to prevent the mounting plate 3 from resetting upwards, the vertical edge is connected below the transverse edge, and the rotating end is positioned at the lower end of the vertical edge.
