Description
Technical Field
The utility model relates to a pneumatic cylinder technical field specifically is a hydraulic swing jar limit load testing arrangement.
Background
With the development of economy and the progress of society, the continuous innovation of technology becomes necessary and social consensus. Various products are developing towards the direction of energy conservation, convenient use, space conservation, safety, high efficiency and the like. The hydraulic cylinder is not an exception as an important execution element in an electro-hydraulic servo system, and the electro-hydraulic servo system is widely applied to various fields, such as the industrial fields of metallurgy, steel rolling, machinery, ships, aviation, aerospace and the like.
In contrast to a hydraulic actuator, which is driven electrically or pneumatically, the volume and mass of the actuator can be reduced considerably for the same output power, so that the inertia is low and the actuator is sensitive. The most important point is that the hydraulic cylinder drives smoothly and can obtain larger force and torque more easily.
Most of the existing hydraulic cylinder pressure tests are static pressure maintaining tests, after a tested hydraulic cylinder reaches a stroke end, medium and high pressure is automatically switched, an ultrahigh pressure pump automatically continues to pressurize a working cavity, oil is stably and effectively supplied through a pre-adjusted overflow valve, the backward position of an electro-hydraulic change valve is kept at the moment, the high pressure plunger pump continuously pressurizes for 1-2min (the pressure is 1.25 or 1.5 times of the working pressure), and therefore a plurality of electromagnetic reversing valves need to be purchased, and the cost is high.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a hydraulic pressure swing jar limit load testing arrangement to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme:
a hydraulic swing cylinder limit load testing apparatus comprising:
a base mounting bracket;
the swinging cylinder mounting seat is fixedly mounted on the base mounting bracket;
the encoder group is arranged on the swinging cylinder mounting seat;
one end of the force arm is connected with the encoder group through a connecting rod, and the other end of the force arm is provided with a load cake for testing the swing cylinder.
As a further technical scheme of the utility model, the swing jar passes through the screw and links to each other with the arm of force.
As a further technical scheme of the utility model, the load cake is provided with a plurality ofly.
As the utility model discloses a further technical scheme again, connecting rod one end is passed through the shaft coupling and is linked to each other with encoder group, and the other end passes through connecting rod installation piece and links to each other with the arm of force, and encoder group can in time take notes rotatory data when the arm of force is rotatory.
As a further technical scheme, install on the pedestal mounting support and be used for its fixed expansion bolts.
Compared with the prior art, the beneficial effects of the utility model are that: through connecting a arm of force on the swing jar, the arm of force end is installed load block and the arm of force and is connected with the encoder, and the encoder is concentric with arm of force rotation axis, and the encoder takes notes rotatory data when the arm of force is rotatory, and test torque passes through the load and stack swing and hydrovalve group data embodiment, has avoided using several electromagnetic directional valve, and the cost is reduced is more practical.
