Description
Technical field
The utility model is related to a kind of for detecting the detection device of sealed product air-tightness more particularly to a kind of no triage
The air tightness detection equipment of survey.
Background technology
Currently, for the air-leakage test of seal cavity, generally use is two kinds of detection methods of inflatable and fountain.
But both sealing propertytest modes there are problems that, be that detection efficiency is all very low first, need compared with
A detection cycle could be completed for a long time, and the accuracy followed by detected is low and the scope of application is limited.
It is special with the matched air-filled pore of detection device, or needs that inflatable detection mode needs seal chamber itself to be measured to have
Door prepares pneumatic head for some or certain a kind of seal cavity to be measured, and this detection mode can not detect the airtight of air-filled pore itself
Property, there is larger error.To not having the seal cavity of air-filled pore, the trepanning with cavity sheet is needed to realize detection, detection
After blocked again, destroy the integrality of seal cavity to be measured itself in this way, while also producing after closure new
Leak point, the leakproofness of seal cavity can not be accurately reflected, and waste entreprise cost, it is after-sales unqualified to increase product
Rate.And fountain needs to consume a large amount of pure water resource, causes the waste and pollution of freshwater resources, and the scope of application is narrower
It is small, it can not be applicable in for being not suitable for contacting the seal cavity of subsidiary electronic component of water.
Invention content
Problem to be solved in the utility model is to provide a kind of air tightness detection equipment, can be widely used in seal cavity
The Fast nondestructive evaluation of air-tightness.
In order to solve the above technical problems, air tightness detection equipment provided by the utility model is provided with detection components and machine
Frame, the detection components include fixture and airtight instrument, and airtight instrument is fixedly mounted in rack, and bottom plate is additionally provided in rack and is led
Rail, the fixture include upper fixture and lower fixture, and lower fixture is mounted on bottom plate, and upper fixture is mounted on guide rail, the lower folder
Tool is provided with stomata, stomata and airtight instrument unicom, is cavity in the middle part of the upper fixture and lower fixture.
Wherein, cylinder or hydraulic pump are installed on the holder, the cylinder or hydraulic pump connect with the upper fixture
It connects, the upper fixture is pushed to be moved along guide rail.
Wherein, the upper fixture matches with the lower fixture administration.
Wherein, the lower fixture is provided with sealing rubber ring.
Wherein, the upper fixture is mounted on by sliding block on guide rail, is connected with the cylinder or hydraulic pump by connecting rod,
The lower fixture is bolted in rack.
Wherein, the detection components are set as multigroup, and the quantity difference of the cylinder or hydraulic pump, guide rail and airtight instrument is not
Less than the quantity of detection components.
When one group of detection components work of the utility model, the design parameter of pre-set product to be measured, by production to be measured
Product are put into the cavity that upper and lower fixture is formed, and upper fixture slide downward are pushed by cylinder or hydraulic pump, with lower clamp shape
At closed cavity, airtight instrument is protected by the air-filled pore on lower fixture to the confined space fast aeration between upper and lower fixture at this time
Pressure a period of time, pressure difference is detected later, the leakage rate of detected product can quickly be obtained according to pressure difference, and then obtain detected
The air-tightness data of product.
Multigroup detection components can be arranged in the utility model, by the independent detection of every group of detection components of console centralized control,
Detection efficiency can greatly be improved.
Description of the drawings
Fig. 1 is stereogram provided by the utility model
Fig. 2 is internal structure chart provided by the utility model
Fig. 3 is upper fixture stereogram provided by the utility model
Fig. 4 is lower fixture stereogram provided by the utility model
Specific implementation mode
To make the utility model straightforward, it is described in detail in conjunction with attached drawing as follows：
As shown in Fig. 1 stereograms provided by the utility model, the present embodiment is that three groups of detection components are in parallel, specifically includes machine
Frame 1 and three groups of detection components, every group of detection components all include lower fixture 2, upper fixture 3 and airtight instrument 4.Airtight instrument 4 is mounted on machine
The side of frame 1, three airtight instrument are disposed vertically, to save space.Fixture 3 and lower fixture 2 are semi-open cavity structure, on
The cavity of a sealing can be formed when lower clamp.Rack is the frame for installing fixed all parts, and rack is divided into
Lower two parts are boundary with bottom plate 5 as shown in Figure 2, and lower half portion is supporting rack, and top half is the installation position of each component,
And outside is equipped with shell, case top is instruction and control section.
Three groups of vertical guide rails 6 are arranged in side by side parallel on holder 1, and upper fixture 3 is slidably mounted on by sliding block on guide rail 6, under
Fixture 2 is mounted by means of bolts on bottom plate 5, and guide rail 6 is using the double guide posts of linear bearing type.The side setting of lower fixture 2 is such as
Air-filled pore 7 shown in Fig. 3, air-filled pore 7 and 4 unicom of airtight instrument.
Three groups of cylinders 8 are arranged in parallel with above rack, cylinder 8 is connect with upper fixture 3 by connecting rod, in the band of cylinder 8
Under dynamic, upper fixture 3 can be moved up and down along guide rail.As shown in figure 4, four bumper posts are arranged in 3 middle part of upper fixture, may be implemented
The steady fastening of fixture 3 and lower fixture 2, prolongs the service life.
Upper fixture 3 and the shape of lower fixture 2 are corresponding, and lower fixture 2 is rectangle, and outer diameter is slightly less than the internal diameter of upper fixture 3,
The pedestal outer diameter of lower fixture 2 is suitable with the outer diameter of upper fixture 3, and the sealing of polyurethane material is provided on the pedestal of lower fixture 2
Cushion rubber 9, when be moved downward to along guide rail 6 under promotion of the upper fixture 3 in cylinder 8 fastened with lower fixture 2 when, the bottom of upper fixture 3
Portion compresses the cushion rubber 9 of lower fixture 2, and confined space is formed between upper fixture 3 and lower fixture 2.
The air-tightness detection method of the utility model can detect the air-tightness of a variety of different types of products, in this implementation
In example, upper fixture 3 and lower fixture 2 can quick dismounting and change, to detect the air-tightness for the product for not having to type.To not
The pre-set design parameter for product to be measured is needed before similar-type products detection, product to be measured is put into lower fixture 2
Cavity in, by consing upper fixture 3 move down with lower fixture 2 clamping form confined space, under airtight instrument passes through
The downward fixture fast aeration of air-filled pore of fixture 2, pressurize detect pressure difference afterwards for a period of time, you can are obtained to quilt according to pressure difference data
The leakage rate of the internal cavities of product is surveyed, and then obtains the air-tightness data of test product.
Traditional inflatable air-tightness detection method is by inwardly inflating, and the outside leakage rate of detection test product determines
The detection method of the air-tightness of test product, detection device provided by the utility model is to detect detected product internal cavities
And the leakage that fixture is formed between cavity above and below the utility model detects the air-tightness of test product, be by external cavity to
The gas leakage of interiors of products cavity to be measured, therefore the work of trepanning and closure need not be carried out to product to be measured, it may be implemented quickly
Non-destructive testing, save enterprise work amount and avoid increasing fault point simultaneously, improve the final yields of test product.
