Description
Technical field
The utility model is related to a kind of detection means, specifically a kind of device for detecting aluminum alloy die casting air-tightness.
Background technology
Now, it is necessary to use many casting in our industrial production, with constantly raising is required, to these casting
Quality requirement also constantly improving, the air-tightness quality of its medium casting is to weigh one of important indicator of its quality quality.
At present, aluminium casting is frequently used in hydraulic valve, hydraulic pump body and the automobile of seal request in the prior art
The parts such as motor body, the defect such as its blow hole, loose can cause seepage, therefore casting is dispatching from the factory and assemble using preceding,
It is required for carrying out air-tight test.
Present enterprise is checked that its concrete operation step is as follows using water seaoning mostly：It is put into after aluminium casting is sealed
In water, to aluminium casting inner chamber injecting compressed air, if defective will have gas permeation to produce angry bubble.This test mode
Minor leakage can not be tested, the severity of seepage can not be judged, judge also to easily cause erroneous judgement by people's range estimation in addition.Not simultaneously
Beneficial to the inspection of typical products in mass production, present assay device structures are relatively simple, it is impossible to which detection is airtight under workpiece working condition
How is property.
Utility model content
The purpose of this utility model is to provide a kind of device for detecting aluminum alloy die casting air-tightness, to solve the above-mentioned back of the body
The problem proposed in scape technology.
To achieve the above object, the utility model provides following technical scheme：
A kind of device for detecting aluminum alloy die casting air-tightness, including base, the base upper end are provided with workbench, work

The utility model structure is novel, and simulation workpiece work is realized in stable, the design that the utility model passes through seal closure
Temperature conditionss when making, the pressure condition being operationally subject to by pressure testing hydraulic cylinder simulation workpiece, then by air pump toward workpiece
Interior inflation, the air-tightness of workpiece is differentiated by observing manometric change, and the utility model can realize that simulation workpiece works
Air-leakage test under state, meets use requirement.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, can in other specific forms realize that this practicality is new
