Other AbstractAn electro-hydraulic power oil cylinder belongs to the technical field of electro-mechanics. The oil cylinder comprises a servo motor, a reversible constant delivery pump, a hydraulic operated check valve, a sensor, a hydraulic cylinder and an oil tank, wherein the servo motor is connected with the reversible constant delivery pump through a shaft joint the reversible constant delivery pump is connected with the hydraulic cylinder the oil tank is communicated with the oil circuit of the hydraulic cylinder and the sensor is arranged on the hydraulic cylinder. The oil cylinder is characterized in that the oil tank is a concave-structured component with a hollow cavity for containing oil, and the shaft joint which connects the servo motor and the reversible constant delivery pump is arranged in the groove of the concave-structured component. The utility model has a simple mechanical structure, which integrates the mounting pieces of the servo motor, the constant delivery pump and the hydraulic operated check valve and the tank into one, thus forming a compact structure and avoiding the disadvantage of fixing each part with one mounting piece in prior art. The utility model has the advantages of low manufacture cost, light weight, small space occupation and convenient transportation.
