Description
Technical field
The present invention relates to a kind of testing machine and in particular to a kind of air tightness detection machine.
Background technology
Air tightness test machine also known as air-leakage test experimental machine, be one kind be widely used in faucet cavity, motor cylinder block,
The equipment of the various sealing member air tightness test such as piston cavity, bend pipe cavity, pressure gauge, air accumulator, can criticize as type of production
Measure on probation it is also possible to conduct is inspected by random samples or use for laboratory.The traditional method of air-leakage test has bubble method, direct pressure method, helium
Mass spectrography etc., generally puts into part to be measured in water and is detected, artificial inefficient operation, and time cost is high.And remaining is airtight
Property testing machine there is also elaboration not, detection speed is also unhappy, and the loaded down with trivial details problem of detection process.
For this reason, notification number discloses a kind of air tightness detection machine for CN205002915U patent of invention in patent database,
It is characterized in that including frame, water tank, clamping part, supporting part and test section, described water tank is added in frame bottom upper surface, institute
The clamping part stated passes through supporting part and frame upper end is connected, and described detection position is in frame bottom.
The solution of above-mentioned patent needs to test the air-tightness of measured object using water tank, and life-time service is fragile, and
There is complex structure, unhandy problem.
Content of the invention
In view of the deficiency of background technology, the technical problem to be solved is to provide one kind tested using air automatic monitoring
Thing air-tightness and the high air tightness detection machine of detection efficiency.
For achieving the above object, the invention provides following technical scheme：A kind of air tightness detection machine, including frame, its
It is characterised by that described frame is provided with rotating disk, described rotating disk is provided with lower mould, is provided with and can move up and down above described lower mould
Mold, described mold connects cylinder, and described cylinder is arranged in described frame, described lower mould and described mold pressure
After conjunction, it is internally formed cavity, and described mold is communicated with the passage of described cavity, and described passage passes through pipeline and little Chu
Gas tank is connected, and described pipeline is provided with the first electromagnetic valve and measuring cell.
The big air accumulator of described pipeline communication, the pipeline of the big air accumulator of described connection is provided with the second electromagnetic valve.
Described lower mould is provided with some object placing cavities, and described mold is provided with corresponding chamber, this object placing cavity with described
Chamber forms described cavity after mold with lower mould pressing.
Described frame is provided with the substandard products alarm lamp corresponding with object placing cavity, described substandard products warning light number order with described
The order of object placing cavity is corresponding.
During operation of the present invention, detected material is put in the object placing cavity of lower mould, cylinder drives mold to push, mold
With lower mould closure, open the first electromagnetic valve, if measuring cell records the volume that pressure value is little air accumulator and little air accumulator, tested
Survey the ratio of the interstitial volume sum after thing is placed in cavity, then explanation measured object air-tightness is good, when pressure value is less than above-mentioned
During ratio, then gas leakage is described.Substandard products warning light during underproof product is detected can be bright, when rotating disk goes to specified location, takes
Go out the detected material corresponding to substandard products warning light.There is simple feature easy to detect.
Brief description
The present invention has drawings described below：
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the top view of the present invention；
