Description

Hydraulic cylinder capable of monitoring stroke Technical Field The utility model relates to the field of hydraulic cylinders, in particular to a hydraulic cylinder capable of monitoring stroke. Background The hydraulic cylinder is a core executing element in a hydraulic system and is responsible for converting hydraulic energy into mechanical energy, and is widely applied to various mechanical equipment. When the hydraulic oil cylinder is used, hydraulic oil enters the cylinder body through a pipeline of the cylinder body to drive a piston in the cylinder body to move, and after the hydraulic oil is separated from the cylinder body, the piston is reset through a spring in the cylinder body. When moving the piston, can not detect the stroke, lead to can not know the piston motion distance to when carrying out accurate processing to partial object, lead to the object to remove the position inaccurately, thereby lead to taking place to influence the problem of pneumatic cylinder result of use. Disclosure of utility model The utility model aims to solve the technical problems that when a piston moves, the stroke cannot be detected, so that the movement distance of the piston cannot be known, and when a part of objects are precisely processed, the movement position of the objects is inaccurate, and the use effect of a hydraulic cylinder is affected. The hydraulic cylinder capable of monitoring the stroke comprises a cylinder body, wherein a piston is arranged on one side of the cylinder body, a pipeline is arranged on one side of the cylinder body, a monitoring device is arranged on one side of the piston, and the monitoring device measures the stroke of the piston through a graduated scale so that an operator can observe and monitor the stroke of the piston. The hydraulic oil cylinder has the advantages that when the hydraulic oil cylinder is used, hydraulic oil is conducted inside the cylinder body through the pipeline of the cylinder body to drive the piston inside the cylinder body to move, at the moment, the monitoring device measures the stroke of the piston through the graduated scale, so that an operator can observe and monitor the stroke of the piston in real time, and after the hydraulic oil is separated from the cylinder body, the piston is reset through the spring inside the cylinder body.
