A non-contact cylinder piston rod position detection structure

Abstract

This utility model discloses a non-contact cylinder piston rod position detection structure, including a cylinder, an inclined detection plate, and an inductive displacement sensor. A cylinder piston rod is disposed inside the cylinder. The inclined detection plate is arranged parallel to the cylinder, with one end connected to the cylinder piston rod. The inductive displacement sensor is spaced below the inclined surface of the inclined detection plate and fixedly connected to the cylinder. When the cylinder piston rod extends, it drives the inclined detection plate to move. The inductive displacement sensor is used to detect the vertical distance to the inclined detection plate. This utility model's non-contact cylinder piston rod position detection structure adopts a non-contact detection method, avoiding the instability and shortened sensor lifespan caused by mechanical friction and wear in traditional contact detection, and also greatly improving detection accuracy.
