Description
Technical field
The utility model is related to a kind of test fixture, particularly a kind of test fixture for CNG pressure sensors.
Background technology
CNG pressure sensors are mainly used in the multipoint injection system of dual-fuel automobile, for detecting gas injection rail combustion gas
Absolute pressure in absolute pressure and inlet manifold.According to the change of two air pressure, electric signal transmission is converted into ECU, ECU is again
According to actual air-fuel ratio, optimal injection gas-time is controlled.Realize the purpose of energy-saving and emission-reduction.
The method of conventional detection CNG pressure sensors is to insert corresponding two air inlet pipe of CNG pressure sensors at present
Top hose is detected.During detection, on two air induction hoses for connecting hoses to correspondence CNG pressure sensors, flexible pipe it is another
One end is connected to pressure controller, by the test pressure of pressure controller output products, due to being flexible pipe, when test pressurization
Easily sealing incessantly causes output pressure shakiness to cause test result to be forbidden to flexible pipe, and flexible pipe is easily jumped out by pressure, easily
Occur dangerous.
Utility model content
The technical problem that the utility model is solved is to provide a kind of CNG pressure sensors simple in construction, easy to operate and surveyed
Trial work is filled, and to improve the operating efficiency of test CNG pressure sensors, reduces testing cost.
In order to solve the above technical problems, technical solution adopted in the utility model is as follows.
A kind of test fixture for CNG pressure sensors, including frock fix bottom plate, frock fix back plate, mounting post,
Limited block, product fixation plate, guide pillar, rectilinear quick-speed jigs, quick clip keel, joint block of gas channel and tracheae quick connector；
The mounting post is installed on the frock and fixes bottom plate；The product limited block and product fixation plate are fixed on described
In mounting post；The guide pillar is fixed on the product and is fixedly mounted on plate；The frock fixation back plate is installed on the frock and consolidated
Determine on mounting base；The rectilinear quick-speed jigs are installed on the frock by quick clip keel and fixed in back plate；It is described
Tracheae quick connector is provided with joint block of gas channel, the joint block of gas channel connection is arranged on the rectilinear quick-speed jigs；
The sealing mounting blocks are fixed on the joint block of gas channel.
Further, the mounting post is fixed on the frock fixation bottom plate by installing screw.
Further, the product limited block and product fixation plate are fixed in the mounting post by installing screw.
Further, the guide pillar is fixed on the product fixed installation plate by installing screw.
Further, the frock is fixed back plate and is installed on by fixed screw on the frock fixed installation bottom plate.
Further, the sealing mounting blocks are fixed on the joint block of gas channel by installing screw.
Further, the mounting post is four.
Further, the tracheae quick connector is two.
Beneficial effect：The utility model is fixedly mounted plate and can test different model by changing product limiting plate and product
CNG pressure sensors, be a kind of test work of the CNG pressure sensors of simple to operate, convenient test and highly versatile
Dress.
Brief description of the drawings
In order that content of the present utility model is more likely to be clearly understood, below in conjunction with the accompanying drawings, the utility model is made
Further details of explanation, wherein,
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of CNG pressure sensors to be detected of the present utility model.
It is expressed as in figure：The rectilinear quick-speed jigs of 1-；2- guide pillars；3- joint block of gas channel；4- seals mounting blocks；5- installs spiral shell
Silk；6- mounting posts；7- frocks fix bottom plate；8- quick clip keels；9- fixed screws；10- tracheae quick connectors；11- frocks
Fixed back plate；12- CNG pressure sensors to be detected；13- product limiting plates；Plate is fixedly mounted in 14- products.
Embodiment
The utility model is further elaborated below in conjunction with the drawings and specific embodiments.
As shown in figure 1, CNG pressure sensor test fixtures, including frock fix bottom plate 7, four mounting posts 6 are by installing
Screw 5 is fixed on frock and fixed on bottom plate 7, then by installing screw 5 product limited block 13 and product fixation plate 14 are fixed into peace
In four mounting posts 6, guide pillar 2 is fixedly mounted on product fixed installation plate 14 by installing screw 5, and frock fixes back plate
11 are arranged on frock by fixed screw 9 is fixedly mounted on bottom plate 7, and rectilinear quick-speed jigs 1 are installed by quick clip keel 8
Fixed in frock in back plate 11, two tracheae quick connectors 10 are installed on joint block of gas channel 3, the connection of joint block of gas channel 3 is arranged on
On rectilinear quick-speed jigs 1, sealing mounting blocks 4 are fixedly mounted on joint block of gas channel 3 by installing screw 5.
As shown in Fig. 2 changing correspondence CNG pressure sensors 12 to be detected, pressure controller extraction tracheae is connected to gas
On pipe quick plug 10, rectilinear quick-speed jigs 1 are promoted to drive joint block of gas channel 3 and sealing mounting blocks 4 descending along guide pillar 2,
So as to seal two tracheaes of CNG pressure sensors 12 to be detected, patching for correspondence CNG pressure sensors 12 to be detected is plugged
Part, pressure controller, which exports corresponding test pressure, can just test the performance of CNG pressure sensors 12 to be detected.This practicality is new
Type is that a kind of installation operation is simple and convenient, good and highly versatile the CNG pressure sensors of uniformity test fixture.
Obviously, above-described embodiment is only intended to clearly illustrate example, and the not restriction to embodiment.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of change or
Change.There is no necessity and possibility to exhaust all the enbodiments.And the obvious change thus extended out or
Among changing still in protection domain of the present utility model.
