Abstract

The invention discloses an electro-servo hydraulic generator. The electro-servo hydraulic generator comprises a rack, a servo motor, an intermediate drive mechanism, a rolling lead screw pair, a guideassembly and an oil cylinder assembly, wherein in the rolling lead screw pair, a rolling lead screw is in drive connection with an output end of the servo motor through the intermediate drive mechanism, and a lead screw nut is fixedly connected with the guide assembly and drives the guide assembly to move in the axial direction; in the oil cylinder assembly, a plunger and the rolling lead screw are coaxially arranged and fixedly connected to the guide assembly, and the plunger does relative motion in the oil cylinder under the drive of the guide assembly to further produce high-pressure hydraulic oil to be output outwards. The generator detects travel of the plunger through a travel displacement sensor, accurate control of oil output of the oil cylinder is realized, hydraulic oil pressureproduced in the oil cylinder is detected through a hydraulic sensor, and closed loop control is formed with the servo motor. The electro-servo hydraulic generator can be used for replacing an existing hydraulic system and a gas-liquid combined system and is small in size, reliable to operate and maintenance-free, and accurate control of oil output and pressure output can be realized.

Description

technical field [0001] The invention belongs to the technical field of servo hydraulic systems, in particular to an electric servo hydraulic generator. Background technique [0002] In the field of servo hydraulic systems, many occasions require a hydraulic source that can precisely control the output oil volume and pressure. The traditional method is to use a hydraulic system consisting of a motor, an oil pump, a proportional valve or a servo valve, or a gas-liquid combination system consisting of a cylinder pushing an oil cylinder. Among them, the hydraulic system is not only complex and bulky, but also high in manufacturing cost, easy to leak, and difficult to maintain; while the gas-liquid system needs to be equipped with a gas source, which has low control accuracy and slow response speed. SUMMARY OF THE INVENTION [0003] In view of the above-mentioned defects in the prior art, the present invention provides an electric servo hydraulic generator, which is used to re...
