Description
Technical field
The present invention relates to equipment and the side in Manufacturing Technology for Automotive Parts field, more particularly to a kind of wheel hub air-leakage test
Method.
Background technology
With flourishing for automobile industry, aluminium alloy wheel hub is as the indispensable part of automobile, with wide city
Field prospect.But come because aluminium alloy wheel hub is cast out, it is possible that sand holes, these sand holes are with the naked eye in casting process
It is difficult to find out, if there are sand holes on wheel hub, load onto and gas leakage is just easy to after tire, automobile is to run at high speed, just have safety hidden
Suffer from, it is therefore desirable to which quality safety detection is carried out to aluminium alloy wheel hub.
Domestic and international widely used aluminium alloy wheel hub air-tightness detection method has wet type air-leakage test method and helium at present
Air-leakage test method.Wet type air-leakage test method is that whether have bubble generation by manual identified, and this method efficiency comparison is low, no
Beneficial to automatic detection is realized, while wet type air-tightness detection method is higher to staff's Capability Requirement, for continuous obvious
The generation of bubble, easily determines that aluminium wheels surface has sand holes, but the bubble that small sand holes are produced is difficult to area with interference bubble
Point, then easily judge by accident, cause accuracy of detection low.Inert gas-helium and helium mass spectrum are needed to use when being detected using helium
Instrument, helium is needed wheel hub being positioned in confined space when detecting, hub inner lumen is vacuumized, right when vacuum values are sufficiently small
The helium of certain pressure value is filled with the outside of wheel hub, if wheel hub wheel rim has leak source, helium gas molecules can pass through leak source, reach wheel hub
Inner chamber；Because hub inner lumen is vacuum environment, the helium gas molecules of entrance can be pumped in helium mass analyzer, be detected by helium mass analyzer
Go out helium molecular number, so as to judge the air-tightness of wheel hub whether in tolerance interval.Although the precision of this detection method detection
It is higher compared to bubble method, but helium air-leakage test method has the following disadvantages in use：1st, helium air-leakage test method is adopted
Detection device is expensive, in the detection, and the loss of helium is also than larger, and helium is as rare gas, expensive, therefore
Overall testing cost is high；2nd, inherently there is certain density helium in air, if misoperation in operation, it is easy to detect
Helium into air, causes the detection of air-tightness inaccurate；3rd, when detecting each wheel hub, in addition it is also necessary to which whole wheel hub is close
It is enclosed among the sealing space of vacuum, the operation that so may result in detection is more complicated, the operating efficiency of detection is than relatively low.
Therefore, it is badly in need of a kind of accuracy of detection height now, detects simple to operate, operating efficiency is high, and testing cost is relatively low
The device and method of new wheel hub air-leakage test.
The content of the invention
