Abstract
The utility model discloses a hydraulic cylinder capable of controlling displacement, which comprises a cylinder barrel. The front end and the rear end of the cylinder barrel are respectively in threaded connection with a cylinder head and a cylinder bottom. A piston is positioned in the cylinder barrel and is in liquid sealing with the inner wall of the cylinder barrel. A piston rod is fixedly connected with the piston. One end of the piston rod protrudes out of the cylinder head. A displacement sensor is fixed on the outer end face of the cylinder bottom. A test probe of the displacement sensor extends into an inner hole of the piston rod through the piston. The displacement sensor transmits a tested signal to a control system. By the non-contact displacement sensor, the utility model measures the displacement of the cylinder, controls stoping and starting of the cylinder at any time and realizes stable and rapid movement of the cylinder so as to meet the use requirements of machine equipment with higher requirements on stroke control accuracy of the cylinder and be suitable for application in the severe environment and operation under high-frequency condition.
