Abstract

The invention discloses a hydraulic oil cylinder performance test device and a test method thereof. The device comprises a test board, an outer barrel, an inner barrel, a clamping mechanism and a vibration exciter, wherein the test board is arranged in a turnover mode around a horizontal axis and is driven by a turnover mechanism; the outer barrel is mounted on the test board, and the rotation axis of the outer barrel is horizontal and is perpendicular to the turnover axis of the test board; the inner barrel is coaxial with the outer barrel, is rotationally mounted in an inner cavity of the outer barrel around the axis, and is driven by a rotating component; the clamping mechanism is arranged in an inner cavity of the inner barrel and used for clamping the periphery of a middle section of a cylinder body of a hydraulic oil cylinder; and the vibration exciter is mounted on the test board. The invention further provides a test method using the device. According to the hydraulic oil cylinder performance test device and the test method thereof, air in the cylinder body is rapidly eliminated before the hydraulic cylinder is tested, so that normal proceeding of follow-up performance testing is guaranteed.

Description

technical field [0001] The invention relates to the technical field of hydraulic cylinder testing, in particular to a hydraulic cylinder performance testing device and a testing method thereof. Background technique [0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion. It has simple structure and reliable operation. When it is used to realize reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap, and the motion is stable, so it is widely used in various mechanical hydraulic systems. [0003] After the design of hydraulic cylinder products, it is often necessary to carry out various tests, such as durability test, pressurization test, etc. The most important step before each test is to remove the air in the cylinder. However, when testing existing hydraulic cylinders, Most of them are fixed, and the air bubbles may exist in some dead ang...
