Abstract

The invention discloses a horizontal hydraulic cylinder deflection and stability test platform and a self-weight deflection test method, comprising left and right bottom supports, rectangular steel frames, cross hinges, and rectangular lifting lug fixing seats, and the cylinder body of the hydraulic cylinder is fixed on the cross hinge. On the rectangular steel frame, the end of the piston rod is connected to the rectangular steel frame through the rectangular lifting lug fixing seat. The rectangular steel frame is positioned and installed on the semicircular fixed sliders on the left and right bottom supports, and can be wound around the center line of the hydraulic cylinder. Turn over 360°, fix the dial gauge at the bottom of the rectangular steel frame, and the measuring head of the dial gauge is fixedly connected with the piston rod of the hydraulic cylinder. The invention can realize the deflection and stability test of the horizontal hydraulic cylinder, and effectively test the mechanical properties of the horizontal hydraulic cylinder; it can realize 360° rotation, and the dial indicator fixed on the rectangular steel frame can measure the initial position and rotation of the frame At the 180° position, the relative displacement of the measuring point of the hydraulic cylinder to the frame measures the deflection value of the hydraulic cylinder's self-weight state, which is simple and easy to operate and low in cost.

Description

technical field [0001] The invention relates to the technical field of hydraulic experiments, in particular to a horizontal hydraulic cylinder deflection and stability test platform and a self-weight deflection test method. Background technique [0002] Hydraulic cylinders are an important part of hydraulic systems and are widely used in construction machinery and ships. Excessive deflection will lead to excessive wear of the cylinder head seal, piston and cylinder wall, resulting in oil leakage or a drop in hydraulic cylinder output. The stability of the hydraulic cylinder is directly related to the safety of the entire engineering structure. The hydraulic cylinder test bench is the necessary equipment for the quality inspection of hydraulic products and the guarantee for the quality monitoring of hydraulic cylinders. At present, the test platform for testing the deflection and stability of hydraulic cylinders is relatively blank, and the cost of testing equipment for sel...
