| Zusammenfassung: | The invention discloses a hydraulic oil cylinder with a position monitoring function. A hole allowing a displacement sensor (5) to be installed is reserved in a fixed end bottom cover (4) of the hydraulic oil cylinder; the displacement sensor (5) is connected and installed at the hole from the outside by virtue of a thread, and subjected to sealing treatment; and a movable element (3) of the hydraulic oil cylinder is subjected to induced reflection reinforcement treatment. According to the hydraulic oil cylinder disclosed by the invention, the displacement sensor is added to the fixed end bottom cover of a common hydraulic oil cylinder, and the induced reflection reinforcement treatment is carried out on the movable element of the hydraulic oil cylinder, so as to response a sensor transmission signal, so that real-time monitoring for the stroke of the hydraulic oil cylinder is realized; and a control system finally realizes accurate control for an action mechanism by virtue of the stroke information.
