Embodiment
Automatic Cycle feeding leakage testing device as shown in Figure 1, that the utility model relates to is on the basis of existing structure; Increased time liquid device 17 that includes shutoff plug 12, this shutoff plug 12 has first state and second state, promptly when first state; Shutoff plug 12 will be communicated with the mouth of pipe 11 sealings; Leak test liquid in the reservoir 8 is under the effect of ambient pressure, by giving the surface that is layed onto automobile axle housing 1 for coating device 16, when the surperficial air pressure of leak test liquid disappears; Owing to return the pressure effect of reclaiming the leak test liquid of storage in the liquid device 17; Second state that shutoff plug 12 is in open returns the leak test flows that reclaim storage in the liquid device 17 and returns in the reservoir 8, has realized the Automatic Cycle utilization of leak test liquid.
Based on above-mentioned design philosophy, the utility model comprises:
Leak test platform 3 is with the waterwall that exceeds upper surface around this leak test platform 3, and the bottom is provided with backwater hole, and when carrying by the automobile axle housing 1 of block head 2 sealings, the leak test liquid that automobile axle housing 1 outside surface is flowed down collects, and flows out through backwater hole.
Return liquid device 17, the top that it is positioned at reservoir 8, what have leak test liquid that storage flowed back to by the water delivering orifice of leak test platform 3 returns liquid device cavity 6, also includes return pipe 4, filtration unit 5, communicating pipe 7 and shutoff plug 12.The backwater hole of the top of return pipe 4 and leak test platform 3 is connected, and the leak test liquid that is flowed out by its bottom flow into back in the liquid device cavity 6 through filtration unit 5.The one of which end probeed into back in the liquid device cavity 6 and with returning liquid device and was connected as the parts that are communicated with back liquid device 17 and reservoir 8 communicating pipe 7, and the other end probes into the bottom of reservoir 8, is shaped as 90 ° of elbow structures, and the mouth of pipe of this end is for being communicated with the mouth of pipe 11.Shutoff plug 12 is installed in through hinged mode and is communicated with on the mouth of pipe 11, and can open and close the connection mouth of pipe 11 through the rotation around the hinged place, to open or close reservoir 8 and to return being communicated with of liquid device 17.
Draft tube 13, it tells the air pressure of leak test liquid surface transport pressure >=0.2MPa that two branch roads store to the enclosed cavity of automobile axle housing 1 and reservoir 8 through pneumatic supply.
Give coating device 16, it comprise be communicated with the flexible pipe 14 that inserts in reservoir 8 cavitys and with the spray equipment 15 that flexible pipe 14 is connected, be used for the leak test liquid that flow out in the reservoir 8 are sprayed at automobile axle housing 1.For guaranteeing that the leak test liquid in the reservoir 8 is fully utilized, the liquid feeding end of flexible pipe 14 preferably is insinuated into the bottom of reservoir 8 internal cavities.
The working method of the instance of this Automatic Cycle feeding leakage testing device is:
At first; Automobile axle housing 1 is placed on the leak test platform 3; Using block head 2 is an airtight cavity with its sealing, and the ambient pressure source is switched to this closed cavity through draft tube 13, opens pneumatic supply and pressurizes to it; Make it to have normal pressure, the pneumatic supply air pressure >=0.2Mpa that selects for use here with respect to external atmosphere pressure.Can also see that from Fig. 1 draft tube 13 is also told a branch road and is communicated to reservoir 8, to it working pressure is provided.The leak test liquid of reservoir 8 inside is closed shutoff plug 12 under the effect of this pressure, breaks off being communicated with of reservoir 8 and time liquid device 17, and through giving the outside surface that is layed onto automobile axle housing 1 for coating device 16.Penetrating crack inside and outside if automobile axle housing 1 has, the gas that overflows at the place, crack so can make leak test liquid produce bubble, judges thus whether the welding quality of automobile axle housing 1 is qualified.
