Description
Art
The present invention is a kind of supercharging equipment of test bench of hydraulic oil cylinder.While test oil cylinder pressure is improved, oil cylinder unbalance loading work shape can also be simulated
State is tested.
Background technology
With generally using for high-voltage oil cylinder, the bearing capacity of hydraulic cylinder is also in raising progressively, it is desirable to which the test pressure of cylinder bench is also needed together
Step is improved.Improving the method for testing stand pressure has two kinds, and one kind is to improve oil cylinder experimental bench pressure, and one kind is increase supercharging device.
Current hydraulic jack experimental bench is usually to use horizontal, static quadrature reactance to carry pressurization experiment, and this and most of vertical, dynamic unbalance loading oil cylinders are actual
Working condition is made a world of difference, it is impossible to simulate oil cylinder actual working state and dynamic duty performance well, carries out testing inspection.
The content of the invention
The present invention, on the premise of original testing stand hydraulic system pressure is not changed, by setting reinforcement test-bed, solves ever-increasing hydraulic pressure
The problem of requirement of cylinder test pressure；By increasing travel mechanism on test-bed, to simulate the working condition of the actual dynamic of hydraulic cylinder and unbalance loading,
Solve testing of oil cylinder can not coincide dynamic, unbalance loading under its working condition the problem of.
Technical scheme
Lever boosting mechanism, a secondary Toggle Force Amplifier for load cylinder driving are set on experimental stand, managed using lever principle and force resolution
By, by reinforcement twice, realize and test oil cylinder reinforcement is pressurized, the purpose of raising test pressure；Secondly utilize the adjustment structure of secondary reinforcement and add
The impulse stroke of carrier fluid cylinder pressure, control, the multiple of regulation reinforcement, meets the requirement of different tests pressure；3rd is along x, y by Mobile Slide
Move and by installation site adjustment structure, realize the working condition experiment of simulated test oil cylinder unbalance loading in direction.
Brief description of the drawings
The present invention is further described with process of the test is implemented below in conjunction with the accompanying drawings.
Accompanying drawing is secondary reinforcement hydraulic cylinder test-bed mechanical structure sketch.
1. test oil cylinder Mobile Slide in figure, 2. test oil cylinders, 3. boosting levers, 4. 2 Toggle Force Amplifiers, 5. 2 reinforcement load cylinders,
6. load cylinder bearing, 7. reinforcement testing stand columns.
Embodiment
As shown in drawings, before experiment, the test pressure value according to required for test oil cylinder 2 calculates the operating pressure and stroke of load cylinder 5,
Regulate the arm of force L1, L2 of a force increasing arm 1 length；Then start-up loading oil cylinder presses, the hinge being made up of two secondary Toggle Force Amplifiers 4
Bar force-increasing mechanism realizes first time reinforcement, promotes a force increasing arm 3 to swing；During swing of force increasing arm 3, lever principle is utilized, is realized second
Reinforcement, the power that most pressurizing cylinder is produced at last amplifies after-applied on test oil cylinder 2 twice.Test oil cylinder 2 is reversed after supercharging, different
On position, regulation pressure reaches test pressure requirement and pressurize is for a period of time, realizes the pressure test of hydraulic jack；Under the conditions of certain pressure, move
Dynamic test oil cylinder movement slide unit 1 (x directions or y directions), realizes the unbalance loading experiment of test oil cylinder 1, while can realize that unbalance loading pressurize etc. is tested.
The reinforcement multiple of test-bed is equal to the reinforcement multiple of toggle mechanism and the product of lever augmented multiple.The reinforcement multiple of two force-increasing mechanisms can be with
Regulation, disclosure satisfy that a range of reinforcement requirement.
