Problems solved by technology

[0003] The existing hydraulic cylinder test bench is in accordance with the national standard "GB / T15622--2005 Hydraulic Cylinder Test Method". The hydraulic cylinder test bench is mainly horizontal and arranged on the top, and the hydraulic cylinder is loaded with the top force in the horizontal direction. and constant lateral force, and in many cases, the engineering hydraulic cylinder is vertical, and the load has axial force and lateral force, and it is constantly changing during the work process. Obviously, the horizontal hydraulic cylinder test bench Cannot fully simulate the actual working environment and working conditions of the hydraulic cylinder
Considering the self-weight of the hydraulic cylinder, the horizontal hydraulic cylinder test requires a guide column device. When the tested cylinder is long, the entire length of the horizontal hydraulic cylinder test bench is longer

Abstract

The invention discloses a single-side adjustable vertical hydraulic cylinder test bed. The single-side adjustable vertical hydraulic cylinder test bed comprises a base, a stand column, a loading cylinder, a cross arm and a tested cylinder, wherein the stand column is installed on the base, the loading cylinder is rotatably installed on the base, the cross arm is erected on the stand column and theloading cylinder, one end of the cross arm is rotatably connected with the stand column, the other end of the cross arm is rotatably connected with a first piston rod of the loading cylinder, the tested cylinder is rotatably installed between the stand column and the loading cylinder on the base, a second piston rod extends out of the tested cylinder to be rotatably connected with the cross arm,and the cross arm, the loading cylinder and the tested cylinder are all located on the same vertical plane. The single-side adjustable vertical hydraulic cylinder test bed is simple in structure and method, conforms to the dynamic state of the hydraulic cylinder in the actual working process and is wide in application range, and by adjusting the installation positions of hinging bases on the crossarm and the base, the test bed can meet the requirements of tests of hydraulic cylinders with different strokes, different lengths and various specifications.

Description

technical field [0001] The invention relates to the technical field of hydraulic cylinders, in particular to a single-side adjustable vertical hydraulic cylinder test bench and a test method. Background technique [0002] After the cylinder is manufactured and assembled, a number of test items such as trial operation, starting pressure characteristic test, pressure resistance test, durability test, leakage test, buffer test, load efficiency test, high temperature test and stroke inspection must be carried out, and the structural strength of the cylinder test bench is required to be sufficient , stiffness, anti-vibration and anti-fatigue, safe and reliable, simulating actual working conditions, in addition to requiring easy to use. As the actuator of the hydraulic system, the hydraulic cylinder is widely used in all walks of life, especially in construction machinery and lifting and transportation machinery. The performance of the oil cylinder is very important to the safety ...
