It is general that pressure is directly applied using forcing press currently for large scale big load product axial compression test, or use group
Box-like pressurized strut compared with complex tool equipment equipment by carrying out pressure-loaded.Nonetheless, for the product of large scale big load, pressure
Experiment is still under pressure the limitation of machine pressure face size or the limitation of pressurized strut installation site, and be under pressure machine itself precision or
The influence of pressurized strut precision, product pressure experiment is difficult accurate realization, and consumes a large amount of manpower and materials.Based on this, this Shen is made
Please case.
The content of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of product axial compression test fitting device.
The purpose of the present invention is achieved through the following technical solutions：
A kind of product axial compression test fitting device, it includes base, inflatable airbag, dividing plate, cover plate, stud and spiral shell
Mother, base is put on level land or on supporter, places inflatable airbag, and air bag is full of the gas of certain pressure, pressure in advance
For 0.5-2.5MPa, then the product placed again above dividing plate, dividing plate and need to carry out axial compression test is placed above air bag, finally put
Cover plate is put, stud is connected on base internal thread by cover plate preformed hole, reserved stud installs nut on the outside of cover plate.Apply and twist
Clamp force square, supplements gases at high pressure to air bag by airbag aeration flexible pipe, inside air bag pressure is monitored by detachable pressure gauge,
When air bag reaches predetermined pressure, test products bear corresponding axial compressive force, so that it is related to measure test products axial compression test
Data.
Further, as preferred：
Described base is as overall structure, and base side wall reserves bolt connecting hole, and base side wall laterally reserved inflation
Airbag aeration hole and the detachable pressure gauge mounting hole of air bag.Integral pedestal can reduce connection requirement, base plane degree and bolt
Hole perpendicularity is met by overall machining, and side wall, which reserves airbag aeration hole and pressure gauge mounting hole, does not influence the pressure examination of product axle
Axial assembly relation is tested, it is simple in construction to be easily achieved.
The airbag aeration flexible pipe installed on described air bag can carry out the bending in 0 ° of -360 ° of angular range, it is ensured that air bag
Smoothly it can be fitted into base.The purpose so designed is that air bag is positioned in base, and flexible pipe can be relatively easy to reserved from base
Airbag aeration is passed in hole, and follow-up assembly relation is not influenceed.
The pressure gauge installed on described air bag is detachable, and air bag pressure is installed again after air bag being loaded into base
Power table.The purpose so designed is that air bag is positioned in base, after balloon positions are placed, and gasbag pressure is installed from chassis outer side
Table, easy to disassemble and manometric reading.
Described dividing plate is placed on above air bag, and certain interval is left with base side wall, and gap is protected between 1-20mm
Card can with airbag gas number move up and down.The purpose so designed is that dividing plate only plays aux. pressure distribution work
With, and laterally not by the pressure in other directions in septum plane, beneficial to the accuracy of product axial compression test data.
Described test products upper and lower end face ensures smooth, so that it is uniform effective to ensure that pressure applies.
Described cover plate is by stud and is bolted to base upper surface, does not have assembly relation with miscellaneous part.
Described air bag inner bag is different according to pressure size, can make multiple inflated hose supplement gasbag pressures.
Described bolt is uniformly distributed, and conventionally quantity is not less than 6, and its one end connect base pre-threaded hole is another
End is connected by nut with cover plate.The distribution that conventional stud is 6, it is ensured that the uniformity of pressure, bolt is more, pressure is about
Uniformly.
Described axial compression test frock can be designed as different shapes according to the profile of product.
The present invention operation principle be：Air bag inner inflatable can produce expansion, and therefore air bag produces pressure to dividing plate,
And base and cover plate have been attached by bolt, appearance and size has been fixed, when the bag inflates, and product is to bear air bag transmission
To the pressure of dividing plate, the pressure that product is born can accurately be controlled by gasbag pressure table.
Compared with prior art, the positive effect of the present invention is：
The limitation of big component-level product axial compression test is solved, frock can adjust work according to the product that need to carry out axial compression test
Size is filled, and experiment is not limited by place, it is not necessary to extra large-scale auxiliary equipment such as forcing press/pressurized strut, greatly subtract
Few experimentation cost, and the frock making is simple, connection is reliable, convenient disassembly, and test data is easy to accurate control while being easy to essence
Really collection, being not required to professional operator can complete.
