Description
Technical field
The utility model is related to a kind of detection technique, more particularly to a kind of air-tightness detection device.
Background technology
This product of automobile oil pan needs to be detected its air-tightness during production.Due to oil sump
Shape is varied, general to be surveyed using artificial to carry out water survey or oil, i.e., enters closed oil sump in water or oil, in water
Oil sump is filled plus compressed air in or, observation engine sump tank with the presence or absence of leakage, this operation labor intensity greatly, work
It is low to make efficiency, sealing element is compressed using artificial, dynamics is not easy to control, and detects unstable quality, and detect the oil being over
Bottom case surface has remaining impurity, is difficult to clean up.
Invention content
Technical problem to be solved in the utility model is to overcome the deficiencies of the prior art and provide a kind of air-leakage test to set
It is standby, it can not only ensure the accuracy of detection, and clean pollution-free.
In order to solve the above-mentioned technical problem, the utility model adopts the following technical scheme that realize：A kind of air-tightness
Detection device, it is characterised in that：The air-tightness detection device includes monitor station and pressure detector, and the monitor station includes upper top
Bar and lower push rod, form test chamber for placing detected member between the upper ejector pin and lower push rod, the upper ejector pin with it is dynamic
Power source connects, and the test chamber is connected to air source, and the pressure detector is connect with air inlet/outlet, for detecting the test chamber
The junction of interior pressure, the upper ejector pin and detected member is equipped with buffer stopper, and the buffer stopper is equipped with and detected member phase
Matched groove, the buffer stopper are equipped with venthole.
The pressure detector uses vertical compression sensor, the vertical compression sensor to be connect with air inlet/outlet.
The junction of the buffer stopper and detected member is equipped with sealing ring.
The buffer stopper uses polyurethane rubber.
The power source is cylinder.
The utility model has the beneficial effects that：Detected member is placed in test chamber, is pushed by cylinder, is pushed up in drive
Buffer stopper is withstood in bar pushing, fixes detected member by buffer stopper, and can ensure that air will not flow by the setting of sealing ring
Enter, after air source is passed through, detects pressure using the vertical compression sensor being connect with air inlet/outlet, strong applicability is conveniently operated, and not
Pollution can be generated to product.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model.
Specific implementation mode
With reference to attached drawing, which includes monitor station and pressure detector 1, and the monitor station includes upper ejector pin
2 and lower push rod 3, the test chamber 4 for placing detected member 5, the upper ejector pin 2 are formed between the upper ejector pin 2 and lower push rod 3
It is connect with power source, the power source is cylinder 9, and the test chamber 4 is connected to air source, the pressure detector 1 and into outlet
Hole connects, and in the present embodiment, the pressure detector 1 uses vertical compression sensor, for detecting the pressure in the test chamber 4,
The junction of the upper ejector pin 2 and detected member 5 is equipped with buffer stopper 6, and the buffer stopper 6 uses polyurethane rubber, utilizes poly- ammonia
Ester rubber per se with elasticity, can play the role of buffering, effective protection detected member 5, the buffer stopper 6 be equipped with
Detected member 5 is just fallen into groove when pushing, is set on the buffer stopper 6 by the groove that detected member 5 matches, buffer stopper 6
There is venthole 7, for the air generated between buffer stopper 6 and detected member 5, the company of the buffer stopper 6 and detected member 5 to be discharged
It meets place and is equipped with sealing ring 8, can ensure that air may not flow by the setting of sealing ring 8, leakproofness is stronger.
Operation principle：By detected member 5, that is, the oil sump drain oil being sealed is placed in test chamber 4, and cylinder pushes,
It drives upper ejector pin 2 to push, withstands the pushing of buffer stopper 6, detected member 5 is fixed in test chamber 4, air source is to test chamber 4 at this time
It is inside filled with the gas of setting pressure, leakage rate is calculated by the detection of vertical compression sensor, judges whether workpiece closes according to leakage rate
Lattice.
