Greatly, and axial force can only be loaded, it is difficult to the effectively operating condition of model engineering mechanical-hydraulic cylinder；Another lever load
Although hydraulic cylinder experimental rig can simulation loading axial force and moment of flexure, loaded using increasing and decreasing counterweight by the way of, load
Power variation is not gentle enough, while tilting moment suffered by device is larger, and bulky, need to be fixedly secured the basis of device.
Utility model content
The characteristics of the utility model comprehensively considers above two loading methods provides a kind of liquid of rocker-arm hydraulic loaded
Cylinder pressure performance testing device, structure is simple, and reliable operation, occupied area is small, can effectively model engineering machinery operating condition.
Technical solution used by the utility model is：A kind of hydraulic cylinder performance test device of rocker-arm hydraulic loaded,
Including connecting bracket, rocker arm, rocker arm support, loading hydraulic cylinder, tested hydraulic cylinder, pedestal.The loading hydraulic cylinder be fixed on
The connecting bracket of pedestal side is connected, and the tested hydraulic cylinder is connected with the connecting bracket for being fixed on the pedestal other side, described to shake
Arm two sides are connected respectively at the loading hydraulic cylinder with tested hydraulic cylinder, connecting rocker arm bracket among rocker arm.
Further, the rocker arm is connected by fixed rotating shaft with rocker arm support, can do fixed-axis rotation, the load liquid
Cylinder pressure is connected with the rocker arm both ends by shaft respectively with tested hydraulic cylinder, when the loading hydraulic cylinder reciprocating motion of the pistons
When, drive the rocker arm to turn over corresponding angle, to apply corresponding load to the tested hydraulic cylinder.
Further, for specific tested hydraulic cylinder, the rocker arm has determining subtended angle, can be different by replacement
The rocker arm at angle changes the motion profile and load characteristic of tested hydraulic cylinder during loaded cycle.
Further, the tested hydraulic cylinder has multiple installation sites on the rocker arm, not according to load magnification ratio
Together, by changing the installation site of the tested hydraulic cylinder, to change the variation range of experimental rig loading force.
The beneficial effects of the utility model are as follows：
1) according to national standard, starting pressure characteristic test, voltage-withstand test, durability test, leakage are carried out to hydraulic cylinder
The performance tests such as test.
2) it compared with traditional cylinder load testing machine to topped hydraulic, is loaded using lever principle, can not only be added
Carry axial force, while moment of flexure can also be loaded, be tested hydraulic cylinder test process be tested hydraulic cylinder movement and excavator swing arm hydraulic cylinder,
The courses of work such as dipper hydraulic cylinder are consistent, and are capable of the operating condition of effectively model engineering mechanical-hydraulic cylinder.
3) it compared with the hydraulic cylinder experimental rig of lever load, is loaded using hydraulic cylinder, without with reloading, energy
Biggish loading force is provided, while device is not by tilting moment, it is safe and reliable to operation.
4) being tested the loaded one end of hydraulic cylinder has multiple installation sites, can according to need the installation position for changing tested hydraulic cylinder
It sets, to adjust the variation range of loading force.
Detailed description of the invention
Attached drawing is used to provide a further understanding of the present invention, and constitutes part of specification, practical with this
Novel embodiment is used to explain the utility model together, does not constitute limitations of the present invention.Fig. 1 is the utility model
Structural schematic diagram.
In figure：1- connecting bracket, 2- loading hydraulic cylinder, 3- rocker arm, 4- rocker arm support, 5- are tested hydraulic cylinder, 6- pedestal.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
Referring to Fig. 1, a kind of hydraulic cylinder performance test device of rocker-arm hydraulic loaded, including connecting bracket 1, load it is hydraulic
Cylinder 2, rocker arm 3, rocker arm support 4, tested hydraulic cylinder 5, pedestal 6.The loading hydraulic cylinder 2 and the connection branch for being fixed on pedestal side
Frame 2 be connected, the tested hydraulic cylinder 5 is connected with the connecting bracket 1 for being fixed on the pedestal other side, 3 two sides of rocker arm respectively at
The loading hydraulic cylinder 2 is connected with tested hydraulic cylinder 5, the intermediate connecting rocker arm bracket 4 of rocker arm 3.
2 rodless cavity one end of loading hydraulic cylinder is connected by shaft with connecting bracket 1, and rod chamber one end passes through shaft and rocker arm
3 sides are connected.Tested 5 rodless cavity one end of hydraulic cylinder is connected with connecting bracket 1, and rod chamber one end is another by shaft and rocker arm 3
Side is connected.When carrying out load test, the piston rod of loading hydraulic cylinder 2 stretches out certain distance, pushes rocker arm 3 to rotate, to test solution
Cylinder pressure 5 applies respective loads.
For specific tested hydraulic cylinder, the rocker arm has determining subtended angle, can pass through the rocker arm of the different subtended angles of replacement
To change the motion profile and load characteristic that loaded cycle is tested hydraulic cylinder in the process.
