The electro-hydraulic composite servo driving system consists of an encoder, a servo motor, a torque sensor, a load, a coupler and a hydraulic motor/hydraulic cylinder, wherein one side of the load is connected with the torque sensor; the torque sensor is connected with the servo motor; the servo motor is connected with the encoder; and the other side of the load is connected with the hydraulic motor/hydraulic cylinder through the coupler. According to the servo motor, high-precision positioning of the servo motion is ensured, the hydraulic motor/hydraulic cylinder ensures that the servo motion obtains high driving force output, and servo driving of the high-precision positioning and the high driving force output can be realized.
Description
Affiliated technical field
The present invention relates to a kind of over-loading operation equipment, especially can realize the electric-hydraulic combined servo drive system of large driving force output and hi-Fix technical goal simultaneously.
Background technique
At present, the actuator that over-loading operation equipment adopted is mainly two big types: electrical servo and hydraulic servo.Electrical servo can be realized high orientation precision, but along with the increase of output drive strength, its volume also constantly increases thereupon, makes volume output than reducing; Though hydraulic servo can be implemented at present the bigger driving force of output under the situation of smaller size smaller, realizes the hi-Fix difficulty.These two types of actuators that over-loading operation equipment adopted all can not realize the technical goal of small volume, large driving force output and hi-Fix.
Summary of the invention
In order to overcome existing over-loading operation equipment actuator can not realize large driving force output and hi-Fix simultaneously under the prerequisite of small volume servo-drive; The present invention provides a kind of electric-hydraulic combined servo drive system; Not only own vol is little for this electric-hydraulic combined servo drive system; Output drive strength is big, and can realize hi-Fix.
The technical solution adopted for the present invention to solve the technical problems is: a side of load connects torque sensor, and torque sensor connects actuating motor, and actuating motor connects encoder; The opposite side of load connects oil hydraulic motor/oil hydraulic cylinder through coupling.When work; Guarantee hi-Fix by actuating motor, and transmit signal through torque sensor and encoder and give oil hydraulic cylinder/oil hydraulic motor that oil hydraulic cylinder/oil hydraulic motor is a foundation with this input signal; Drive load through coupling; Realization is guaranteed large driving force output to the amplification of driven by servomotor torque, makes electric-hydraulic combined drive system possess the performance of hi-Fix, large driving force output.
The invention has the beneficial effects as follows, can when electric-hydraulic combined servo drive system has large driving force output, realize hi-Fix, and the whole system volume be little.
