Description
Technical field
It is especially a kind of for testing the special of fuel tank positive/negative-pressure durability the present invention relates to test fixture design field
Use tooling.
Background technique
The normal operating conditions needs of fuel tank continuously switch under the conditions of the positive/negative-pressure alternation of specific amplitude, and continuous in this way
It switchs how many subsurface or each section does not generate fatigue cracking, i.e. the positive/negative-pressure durability of fuel tank, be the pass for determining fuel tank quality
Key, thus need to test the positive/negative-pressure durability of this fuel tank.The existing positive/negative-pressure durability to this fuel tank into
Row test is typically all manually to use cylinder manual test to fuel tank, and this test method test result was both inaccurate, and labour is strong
Degree is again big, and testing efficiency is very low.Thus need to design a set of profession in the tooling of test fuel tank positive/negative-pressure durability, energy is quasi-
Really, efficient to test fuel tank positive/negative-pressure durability.
Summary of the invention
The problem to be solved by the invention is to provide a kind of fuel tank positive/negative-pressure durability test toolings, to solve existing test
Mode result inaccuracy, the low problem of testing efficiency.
To solve the above-mentioned problems, the technical scheme is that this fuel tank positive/negative-pressure durability test tooling includes using
Test device is equipped with by the oil tank frame for placing fuel tank, the oil tank frame, the test device includes installing on the support frame
At the top of the motion bar of the identical and arranged side by side active cylinder in direction and passive cylinder, the active cylinder and the passive cylinder
It is connected by a link block, one and the active cylinder and described is equipped between the active cylinder and the passive cylinder
Passive cylinder guide rod arranged side by side, one end of the guide rod is set on the link block, in described on the guide rod
The travel switch contact position of active cylinder end is equipped with contact, and two travel switches are connected with counter, described passive
Cylinder is equipped with the air inlet of connection fuel tank, and the passive cylinder is equipped with regulating the qi flowing in the channels at the outlet side of connection fuel tank air inlet and switchs.
In above-mentioned technical proposal, more specifically scheme may is that the passive cylinder is equipped with noise reduction plug.
It is further: to be set on the active cylinder there are two travel switch, the air inlet pipe of the active cylinder is connected with electricity
The air inlet of the gas outlet of magnet valve, the solenoid valve is connected with throttle valve.
By adopting the above-described technical solution, compared with prior art, the present invention has the following advantages:
One test device of this fuel tank positive/negative-pressure durability test Fixture Design by two cylinders is using high pressure gas
Power resources, active cylinder are passive cylinders providing power, and passive cylinder provides positive/negative-pressure for fuel tank；Active cylinder is high in access
After calming the anger, by relay and solenoid valve control its direction of motion, two travel switches on active cylinder with guide rod
Issue conversion signal after upper contact pad, passive cylinder converting motion direction immediately；Such oil cylinder requires 5000 in different condition
~60000 tests, to observe whether surface or each section generate fatigue cracking.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the embodiment of the present invention.
Specific embodiment
The embodiment of the present invention is described in further detail with reference to the accompanying drawing:
This fuel tank positive/negative-pressure durability test tooling as shown in Figure 1, it includes the oil tank frame 10 for placing fuel tank 7.
Test device is equipped with by oil tank frame 10, test device includes that the both direction that is mounted on support frame 14 is identical and arranged side by side
It is connected at the top of the motion bar of cylinder, active cylinder 2 and passive cylinder 5, active cylinder 2 and passive cylinder 5 by a link block 12,
The guide rod 13 being arranged side by side with cylinder, guide rod 13 are equipped between two cylinder, that is, active cylinders 2 and passive cylinder 5
One end be set to 12 on link block, set on active cylinder 2 there are two travel switch 3 and its air inlet pipe 17 connection solenoid valve 15 go out
The air inlet of port, solenoid valve 15 connects throttle valve 16.In 3 contact of the travel switch position of 2 end of active cylinder on guide rod 13
Contact 4 is installed, two travel switches 3 are connected with counter, and counter is mounted on 1 in control cabinet, is additionally provided with out in control cabinet
Pass, relay etc..The air inlet of passive cylinder 5 connects fuel tank 7 by tracheae, and passive cylinder 5 goes out in connection 7 air inlet of fuel tank
Regulating the qi flowing in the channels switch 6 is equipped at gas end, the other end of passive cylinder 5 is equipped with noise reduction plug 11.
Mode of operation: positive/negative-pressure alternation is to simulate the breathable properties of fuel tank 7 in actual use, and fuel tank 7 fills before testing
Each opening is sealed after the water of upper rated capacity, stays an air inlet blow-by, and installs two for observing inside on fuel tank 7
Fuel tank 7 is connect with 5 one air inlets of passive cylinder using tracheae by the positive-negative pressure gauge 8 and 9 of air pressure, installs water later in oil
Pressure buffer of 7 internal upper part of case still there are segment space as fuel tank 7 in routine use.Active cylinder 2 is that passive cylinder 5 mentions
For power, passive cylinder 5 is that fuel tank 7 provides positive/negative-pressure；Active cylinder 2 passes through relay and electromagnetism after accessing high pressure gas
Valve 15 controls its direction of motion, and two travel switches 3 on active cylinder 2 issue after contacting with contact 4 on guide rod 13 to be turned
Change signal, passive cylinder 5 converting motion direction immediately；Such fuel tank requires 5000~60000 tests in different condition, to see
It examines surface or whether each section generates fatigue cracking.
