Small lifting hydraulic cylinder test bench

Abstract

The invention discloses a test bed of a miniature lifting hydraulic cylinder. The test bed comprises a bottom plate, a loading balance weight plate, a plurality of guide columns, a plurality of guide column fixing seats welded to the bottom plate, a plurality of guide seats welded to the loading balance weight plate, a plurality of support columns and a miniature lifting hydraulic cylinder fixing seat, wherein each guide column separately penetrates through one guide seat on the loading balance weight plate and is inserted into one guide column fixing seat, the guide columns are connected with the guide seats and the guide column fixing seats through steel-backed bearings, jackscrew holes are formed in the guide column fixing seats, and the guide columns are fixed to the bottom plate through jackscrews penetrating through the jackscrew holes; and the support columns are arranged between the bottom plate and the loading balance weight plate, and the bottom plate is connected with the bottoms of the support columns and the miniature lifting hydraulic cylinder fixing seat through threads. The structure is simple, all parts are connected in an assembling manner, maintenance is convenient, the universality is high, the actual use working conditions of the miniature lifting hydraulic cylinder can be fully simulated, and the use performance of the hydraulic cylinder can be more effectively examined.

Description

technical field

[0001] The invention relates to the field of hydraulic cylinder tests, in particular to a small lifting hydraulic cylinder test bench. Background technique

[0002] The hydraulic cylinder is an important actuator in the hydraulic system. Its performance not only determines the reliability of the hydraulic system, but also affects the normal operation of construction machinery and equipment. In the actual production of hydraulic cylinders, the performance of hydraulic cylinders is generally tested through hydraulic cylinder test benches and loaded hydraulic cylinders on the test benches, but it is still impossible to completely simulate the actual working conditions of hydraulic cylinders, such as forklift lifting hydraulic cylinders. During the test, the general hydraulic test bench cannot simulate the use of the hydraulic cylinder when the weight is similar to free fall. In addition, in addition to custom-made processing test benches based on actual needs, ...
