Detailed description of the invention
Should be appreciated that specific embodiment described herein is used only for explaining this utility model, be not used to limit this
Utility model.
Being the structural representation of air-tightness tester in this utility model one embodiment referring to figs. 1 through Fig. 3, Fig. 1, Fig. 2 is
The structural representation of the test fixture of air-tightness tester in this utility model one embodiment, Fig. 3 is this utility model one enforcement
The structural representation of the hold down gag of air-tightness tester in example.
A kind of air-tightness tester, including the test fixture 2 being arranged on workbench 1 and hold down gag 3, in order to driving pressure
First drive mechanism 4 of tight device 3 rise and fall, in order to drive the second drive mechanism 5 that test fixture 2 moves along a straight line and
In order to control the first drive mechanism 4 and controller (not shown) of the second drive mechanism 5, the second drive mechanism 5 drives to be surveyed
Trial work fills 2 underfaces being in hold down gag 3, and with hold down gag 3 para-position.
This utility model provides a kind of air-tightness tester, drives hold down gag 3 to rise by arranging the first drive mechanism 4
Descending motion, the second drive mechanism 5 drives test fixture 2 to move along a straight line, and when tested, the second drive mechanism 5 drives test work
Filling underface and hold down gag 3 para-position of 2 to hold down gag 3, first drives structure 4 to drive hold down gag 3 to decline and test work
Fill 2 to closely cooperate thus test.Air-tightness tester automaticity of the present utility model is high, improves work efficiency,
The accuracy of test is protected.
Concrete, in the present embodiment, the first drive mechanism 4 is preferably the first cylinder, is reaching the phase while driving lifting
The position hoped is to 3 one pressure vertically downward of hold down gag.Second drive mechanism 5 is preferably the second cylinder, and test fixture 2 exists
The driving of cylinder is issued to desired position, and the most desired position is the underface that test fixture 2 is positioned at hold down gag 3.?
In other embodiments, the first drive mechanism 4 and the second drive mechanism 5 can be motor-driven mechanism, can also be hydraulic-driven
Mechanism.
With reference to shown in Fig. 2, in the present embodiment, test fixture 2 includes cavity 21, slide rail 23, slide unit 24, and cavity 21 is used for pacifying
The product of the required test of dress, in the present embodiment, cavity 21 is shaped as rectangle, it will be understood that in other embodiments, cavity
Other polygonal shape that the shape of 21 can adapt with product, slide rail 23 is arranged on workbench 1, for bearing test work
Filling 2 slips, slide unit 24 is arranged on slide rail 23, drives test fixture 2 to slide on slide rail 23, at the cavity 21 of test fixture 2
Surrounding is provided with mounting groove 22, is used for placing sealing ring, and arrange that the effect of sealing ring is to seal product is more preferable, in order to survey
The result of examination is the most accurate.In the present embodiment, the position between two slide rails 23 of workbench 1 offers installation the second driving
The bar-shaped trough 11 of mechanism 5, certainly, the installation site of the second drive mechanism 5 may also be arranged on the surface of workbench 1, if energy
Enough drive test fixture 2 linear motion can, here, do not make concrete restriction.
With reference to shown in Fig. 3, in the present embodiment, hold down gag 3 includes mounting plate 31, linear guide 32, push pedal 33, pressure
Plywood 34, mounting plate 31 is for installing the first drive mechanism 4, and linear guide 32 is used for supporting mounting plate 31, push pedal
33 are connected with the first drive mechanism 4, and force fit plate 34 is connected with push pedal 33, and push pedal 33 is socketed on straight line by linear bearing 35 and leads
On bar 32, linear guide 32 is arranged on workbench 1, and the sidewall of force fit plate 34 arranges an air inlet (not shown), this reality
Executing in example, the preferred installation position of air inlet is access and the motion of board at the rear portion of force fit plate 34, beneficially source of the gas, in peace
Also having installed protective cover 7 in dress fixed plate 31, safety is high, effectively eliminates safe hidden trouble.During test, the first drive mechanism 4 is driven
Move push pedal 33 thus drive force fit plate 34 to move towards the direction of workbench 1 in linear guide 32 so that force fit plate 34 and survey
Trial work fills 2 and closely cooperates, and product is carried out air tightness test.
In the present embodiment, also including the air pressure detection sensor 6 for detecting interiors of products gas pressure, air pressure detection passes
Sensor 6 is arranged on the side of workbench 1.Display screen can also be set, for showing test process and the survey of air-tightness tester
Examination data.
This utility model air-tightness tester work process is: is first placed in test fixture 2 by product, presses startup and open
Closing, the second drive mechanism 5 drives the underface of test fixture 2 to hold down gag 3, the first drive mechanism 4 to drive hold down gag 3 times
Fall closely cooperates with test fixture 2 so that product to be tested is in sealing state, now, starts the air inlet toward force fit plate 34
Mouthful filling test gas so that test gas enters in cavity 21, due to the sealing function of sealing ring, the pressure in cavity will be by
Cumulative greatly, when reach set test pressure time, be automatically stopped inflation, and start timing, after reaching the setting time, observable gas
The situation of pressure detection sensor 6, if the air pressure that air pressure detection sensor 6 detects is more stable, does not change, that
Just illustrating that the air-tightness of product is preferable, if the air pressure change that air pressure detection sensor 6 detects is relatively big, that just illustrates product
Air-tightness is poor.
These are only preferred embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model, every
