Same side loading hydraulic cylinder test bench

Abstract

The invention discloses a hydraulic cylinder test bed for same-side loading. The test bed comprises a frame, a positioning device, a piston rod head connecting device, a support cylinder lifting platform, a support rod lifting platform and two loading cylinders, wherein the two loading cylinders are symmetrically fixed on two sides of the frame; the tail end of a tested cylinder body is arranged on the positioning device; the poisoning device can be positioned on different axial positions of the frame; three piston rod heads are connected with each other by the piston rod head connecting device; the loading cylinder and the tested cylinder are located on the same side of the connecting device; the tested cylinders with different model numbers can be arranged between the positioning device and the piston rod head connecting device; the axis of a loading cylinder body and the axis of the tested cylinder body can be located in the same plane through the support cylinder lifting platform; and the piston rod head connecting device is arranged on the support rod lifting platform. According to the test bed disclosed by the invention, hydraulic cylinders with different model numbers can be arranged by same-side loading, so that the space is saved; and the hydraulic cylinder test bed is high in universality, simple to operate, low in cost and beneficial to popularization and promotion.

Description

technical field [0001] The invention belongs to the technical field of hydraulic pressure, and in particular relates to a same-side loading hydraulic cylinder test bench capable of testing different bores and different strokes. Background technique [0002] Hydraulic transmissions have been used in machinery for hundreds of years. With the development of hydraulic technology, hydraulic cylinders have been widely used, especially double clevis hydraulic cylinders, which occupy an important position in the fields of construction machinery and ships. Once the hydraulic cylinder fails, it will seriously affect its normal operation, causing major economic losses and even endangering life and health. The hydraulic cylinder performance test bench designed in accordance with the national standards requires that the loaded hydraulic cylinder and the hydraulic cylinder under test are on top, which takes up a lot of space and the hydraulic cylinder under test has a single model. Due ...

Problems solved by technology

Once the hydraulic cylinder fails, it will seriously affect its normal operation, causing major economic losses and even endangering life and health

The hydraulic cylinder performance test bench designed in accordance with national standards requires that the hydraulic cylinder be loaded on top of the tested hydraulic cylinder, which takes up a lot of space and the tested hydraulic cylinder has a single model

Due to the limited space, many test benches cannot carry out top-to-top loading, and can only provide back pressure or "top wall" to simulate loading, and the test effect is poor
