Hydraulic-cylinder lateral force testing device

Abstract

The invention discloses a hydraulic-cylinder lateral force testing device. The hydraulic-cylinder lateral force testing device comprises a base, a tested cylinder support, a tested hydraulic cylinder, a lateral force loading device, a sliding base, an axial loading cylinder, a supporting base, a connecting device and a loading cylinder support. The hydraulic-cylinder lateral force testing device can well simulate a hydraulic-cylinder lateral force test of the loaded situation of the hydraulic cylinder under the action of lateral force, can be used for carrying out not only conventional tests but also lateral force tests on the hydraulic cylinder and can be used for completing not only the lateral force test of the hydraulic cylinder under the no-load operating condition but also the lateral force test of the hydraulic cylinder under the on-load operating condition. Acting points of the lateral force are located on the cylinder body of the tested hydraulic cylinder, and loading of different types of the lateral force can be achieved only by controlling the magnitude pressure of a lateral force loading cylinder. The hydraulic-cylinder lateral force testing device is compact in structure, low in manufacturing cost and convenient to disassemble, assemble and adjust. The corresponding testing device and a corresponding testing method are provided for performance of the hydraulic cylinder under the action of the lateral force, and the testing technology of the hydraulic cylinder is perfected.

Description

technical field [0001] The invention belongs to the technical field of hydraulic cylinder tests, in particular to a hydraulic cylinder lateral force test device. Background technique [0002] As the main actuator of construction machinery, the performance of the hydraulic cylinder directly affects the use of the whole machine, and the generation of lateral force is related to the performance of the hydraulic cylinder. Under normal circumstances, hydraulic cylinders will generate lateral force, which will cause some problems, such as abnormal noise, crawling, oil leakage, and even damage to structural parts, etc., which will cause the host system to fail to work normally and damage the interests of customers. [0003] The utility model patent with the patent number CN201412416Y discloses an oil cylinder test device, which has a frame, a test oil cylinder is fixed on the frame, and a radial loading device and a moving device that can apply a radial load to the test oil cylinde...

AI Technical Summary

Problems solved by technology

The oil cylinder test device involved in this utility model patent fixes the test oil cylinder on the frame, thereby ignoring the influence of the hydraulic cylinder's own gravity, and the self-weight of the hydraulic cylinder itself is an important reason for its lateral force; the oil cylinder test device The loading device only includes the radial loading device, that is, the radial loading test can only be carried out when the tested hydraulic cylinder is running without load, but the actual situation is that most hydraulic cylinders will be subjected to lateral force when running with load; the cylinder test device The mobile devices include flatbed trucks, eccentric load cylinders, etc. The test device itself is heavy, and the test process will generate a large inertial force, but the actual working conditions of the hydraulic cylinder are not like this
