Servo swing oil cylinder

Abstract

The utility model belongs to hydraulic equipment technical field, concretely relates to a kind of servo swing oil pressure cylinder, including cylinder body, piston, push rod, sealing end cap and hydraulic oil pipeline, the piston inside is embedded with permanent magnet, the cylinder body outside is symmetrically provided with magnetic induction proximity switch;The magnetic induction proximity switch is configured to trigger reversing signal when piston moves to preset position, and the hydraulic oil flow direction is switched by electromagnetic valve, the servo swing control of piston is realized;The sealing end cap is set to both ends of cylinder body, and the inside is equipped with buffer washer;The hydraulic oil pipeline is controlled by electromagnetic valve, the hydraulic oil pipeline is communicated with the oil inlet and oil return port opened on cylinder body, magnetic induction switch can accurately trigger reversing signal when piston moves to preset position, the switching of hydraulic oil flow direction is realized, to ensure that the servo swing control of piston is more stable and accurate, which not only reduces the unexpected shutdown of equipment due to signal error, but also can be applied to more application scenarios.
