Description
Technical field
The utility model relates to a kind of negative pressure air tightness test toolings, for testing lithium electricity forming probe bed vacuum cavitations circuit
Air-tightness.
Background technique
As rectangular lithium ion battery with aluminum shell applications in various fields is more more and more universal, people's square shaped aluminum hull lithium-ion electric
The quality in pond has a higher requirement, and negative pressure is melted into this technique also gradually at the critical process in battery process, and negative pressure
The general quantity of forming probe bed is relatively more, and the leakproofness of negative pressure line is again particularly important, and traditional negative pressure line test is by negative pressure
Collecting pipe, manifold blocks are impregnated in water, are then blown, and have bubble-free by observation to detect whether gas leakage, so not only efficiency
Lowly, some negative pressure are also possible to unqualified under this verification method with the product of air-tightness qualification, then it is a kind of can quickly,
Accurate validation negative pressure line, the tooling of connector air-tightness are with regard to necessary.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned deficiencies of the prior art, and provide a kind of negative pressure air tightness test
Tooling, whole small and exquisite, the light easy to carry and mobile, air-tightness convenient for quickly testing all gas parts in existing negative pressure circuit.
The technical solution of the utility model is: including rack, upper rack is equipped with manifold blocks, and machine frame inside is sent out equipped with vacuum
Raw device filters pressure regulator valve, negative pressure pressure-regulating valve, connector storage box, has a transverse passage-way, multiple and transverse passage-way inside manifold blocks
The subchannel being connected, is equipped with test splice at each subchannel mouth, and test splice is located at manifold blocks upper surface, pressure vacuum gauge and
Manifold blocks connection, manifold blocks side surface are equipped with the inlet suction port being connected with transverse passage-way, and vacuum generator connects through filtering pressure regulator valve
Road one is taken over, negative pressure source is connect through negative pressure pressure-regulating valve with pipeline two, and the hand valve positioned at upper rack is loaded on pipeline one, pipe
On road two, pipeline one, pipeline two are corresponding with inlet suction port respectively.
The upper rack is equipped with panel, and manifold blocks, hand valve are located on panel, and machine frame inside is equipped with vertical plate, and filtering is adjusted
Pressure valve, negative pressure pressure-regulating valve are loaded on vertical plate, and bottom of the frame is equipped with bottom plate, and vacuum generator is loaded on substrate.
The connector storage box is loaded on substrate.
The rack side is equipped with side plate, knob, power taking plug is housed on side plate, vacuum generator connects through electric wire one
Knob is connect, knob connects power taking plug through electric wire two.
The pressure vacuum gauge is located at upper rack.
It is connect in the middle part of the pressure vacuum gauge and manifold blocks.
When conventional negative presses loop-around test, negative pressure tests environmental structure trouble, and poor mobility；Zero removed when not in use
Part is easy to be lost；The components that negative pressure part need to be tested are more, and traditional test compatibility is poor；The environment wiring cloth temporarily built
Pipe is more chaotic, it appears that relatively more mixed and disorderly.A complete machine is made into the utility model structure, it is whole small and exquisite, light easy to carry
And movement, the air-tightness of the gas part of existing negative pressure circuit various specifications can be tested；Magazine is placed with connector in equipment, can be stored
Temporary unused connector and other components；It can all be tested when having negative pressure source and without negative pressure source, when having negative pressure source,
Main pipeline is directly connected to negative pressure source, generates negative pressure with vacuum generator when no negative pressure source.
The utility model is integrally small and exquisite, light, easy to remove and transport；It can be tested by the different types of connector of installation negative
Push back the components of road various specifications；It is reserved with vacuum generator erection joint, in no negative pressure source, can also be occurred with vacuum
Device generates negative pressure and is tested；There is connector storage box, various terminal can be placed.
