Background technology
Traditional ball cover structure pressurising test is to apply uniform aerodynamic loading by wind-tunnel, or passes through gas by closed environment
Pressure applies uniform load.But, wind tunnel test cost is high, and air pressure-loading safety cannot ensure easily occur that air pressure-loading is quick-fried
, there is the biggest potential safety hazard in fried phenomenon.
Well-distributed pressure load is applied in ball cover structure, if testpieces effectively not fixed and using pressurizing device pressurising,
Will be unable to carry out this type of test.
Summary of the invention
The present invention solves the technical problem that traditional ball cover structure pressurising experimentation cost is high, safety is low, it is provided that a kind of
Ball cover structure pressurising test fixture, good airproof performance, fixed, it is simple to realizing pressure loading and apply, the life-span is long, low cost, peace
Complete reliable, effectively solve the drawback of traditional ball cover structure pressurising test method.
In order to solve the technical problem of the present invention, the present invention is achieved by the following technical solutions: a kind of ball cover structure
Pressurising test fixture, including pressurising container 1, ozzle 2 and end cap 3, described ozzle 2 is fixed on bottom described pressurising container 1, described
End cap 3 is arranged on described pressurising container 1 top open part；Described pressurising container 1 includes the pressurising drive end bearing bracket being arranged on bottom it
11, chamber wall 12 and the container transition end cap 13 being arranged on its top；Described end cap 3 is fitted tightly over described container transition end cap
On 13, described ozzle 2 is fixed on described pressurising drive end bearing bracket 11.
Preferably, it is provided with rubber washer between described end cap 3 and described container transition end cap 13, plays sealing function, carry
Sealing between high test fixture and ball cover structural test part 4.
Preferably, it is provided with packing ring between described ozzle 2 and described pressurising drive end bearing bracket 11, plays sealing function, good airproof performance.
Preferably, described packing ring is nylon washer or copper washer.
Preferably, described pressurising drive end bearing bracket 11, chamber wall 12 and container transition end cap 13 welding fabrication.
Preferably, described ozzle 2 is two, and one is pressurising ozzle, and one is pressure measurement ozzle.Pressurising ozzle can connect hands
Shaking pump or high-pressure air source, pressure measurement ozzle connects Pressure gauge, is full of water, it is ensured that safety, examination before test in hermetic container
Pressure is applied by hand pump or high-pressure air source step by step by pressurising mouth during testing, and by pressure gauge reading.Because test
It is filled with water in fixture, even if the phenomenon that fixture ruptures occurs, also will not injure the safety of on-the-spot testing crew, safety
High.
Compared with prior art, the present invention obtains and provides the benefit that:
A kind of ball cover structure pressurising test fixture that the present invention provides, is possible not only to effective fixation test part, and structure is simple
Single, safety coefficient height.A kind of ball cover structure pressurising test fixture that the present invention provides, easily manufactured, device stability is high, safety
Reliably, good airproof performance, life-span long, low cost, it is simple to realize pressure loading and apply, effectively solve wind-tunnel and load and direct gas
The drawback of pressure load test method.
