Embodiment Construction
[0010] Such as figure 1 , 2 As shown, the inner case 4 is set directly above the water tank 3, and the upper guide rod 2 and the lower guide rod 12 are connected and pass through the inner case 4 from bottom to top. The lower end of the lower guide rod 12 is fixedly connected to the water tank 3, and the lower guide rod 12 is fixed on the water tank 3 with a fixed guide rod nut 11 at this connection. The upper end of the upper guide rod 2 is located outside the inner box 4 and connected to the connecting plate 1 of the oil cylinder guide rod. The oil cylinder guide rod fixing plate 10 is arranged between the oil cylinder guide rod connecting plate 1 and the upper surface of the inner box 4 . Fix and connect the front end flange of the oil cylinder 8 to the oil cylinder guide rod fixing plate 10 with the hexagon socket head screw, the oil cylinder piston rod 9 and the oil cylinder guide rod connecting plate 1 are locked with the nut 7, and the upper guide rod 2 passes through...

The invention discloses an automatic watering device of horizontal gas tightness testing machine. An inner box is arranged above a water tank; an upper guide rod, and a lower guide rod are connected and then penetrate the inner box from up to down; the lower end of the lower guide rod is fixedly connected with the water tank; the upper end of the upper guide rod is connected with the connecting board of the guide rod of an oil cylinder; the fixing board of the guide rod of the oil cylinder is arranged between the connecting board of the guide rod of the oil cylinder, and the upper surface of the inner box. The automatic watering device of horizontal gas tightness testing machine adopts the way of driving through a hydraulic cylinder, and uses a hydraulic pressure to lead the water stored in the water tank to flow into the water channel of a tray rack for holding a hub during testing and lead the water to return to the storage water tank after finishing testing. The work stroke of the oil cylinder can be adjusted according to the central heights of hubs with different specifications, thereby controlling the water volume entering a hub test area; moreover, the work process is more reliable and stable.
Description
technical field [0001] The invention relates to a horizontal air tightness testing machine, in particular to a water tank device thereof, which is suitable for testing the air tightness of aluminum alloy wheel hubs of automobiles. Background technique [0002] At present, the water tank of the horizontal air tightness testing machine on the market is injected with an appropriate amount of water when it is working, and then the water tank moves up and down under the control of the hydraulic cylinder, injecting the water in the water tank into the operating body, so that the wheels and hubs are all immersed under the water surface do experiments. The disadvantage of this structure is that the water tank vibrates during the lifting process, which makes the whole horizontal air tightness testing machine unstable and generates noise pollution. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide an...
