AI Technical Summary
In existing multi-functional compression and shear testing machines, the smooth surface of the rolling shaft results in low friction of the pad, leading to inaccurate positioning when the hydraulic cylinder is pulled.
A screw jack is used to lift the platform, and the platform and base are precisely positioned by a sliding component and a hydraulic push rod. The combination of electric and hydraulic push rods ensures that the platform slides on the slide rod and is accurately positioned.
Sufficient friction between the stage and the base was achieved, ensuring that the stage could be accurately positioned, thus solving the problem of inaccurate positioning in existing technologies.
