Electro-hydraulic actuator of hydraulic integration machine

Abstract

The invention provides an electro-hydraulic actuator of a hydraulic integration machine, which comprises an electric control system, a hydraulic system, a hand operation mechanism, an oil tank and an oil cylinder, wherein the electric control system is connected with the hydraulic system, the hydraulic system is respectively connected with the hand operation mechanism and the oil tank, and the oil tank is connected with the oil cylinder. The invention is characterized in that the hydraulic system comprises an oil path and a hydraulic integration block, wherein one end of the hydraulic integration block is connected with the electric control system, the other end of the hydraulic integration block is connected with the hydraulic cylinder through a gear two-way pump, and the hydraulic cylinder is connected with a disc valve. Compared with the prior art, the electro-hydraulic actuator of the hydraulic integration machine of the invention can realize the regulation and the cut-off control of the valve, the huge hydraulic station of the hydraulic control system is omitted, the size is greatly reduced, the materials are saved, and the investment is reduced. The invention has the advantages of complete function, compact structure, small size, light weight, fast response and the like.

AI Technical Summary

Benefits of technology

This new type of electric or pneumatic powered device uses an electrical signal instead of water pressure for controlling its movement. Unlike previous designs that had multiple large components like springs, this design allows for precise positional changes without requiring significant maintenance over time. Its technical effect is improved efficiency compared to existing systems while reducing space requirements by saving material and making it lighterweight than older methods such as spring mechanisms.

Problems solved by technology

This patented technical problem addressed in this patents relates to traditional hydrauled integrated electric machine (EML) hydrauike actuator designs that have issues related to their size and potential leaks during operation due to direct connection between them without proper sealing measures.
