Abstract
The invention discloses a stroke sensor testing device which comprises a chuck, a fixing seat and a magnetic ring. The chuck and the fixing seat are used for fixing the two ends of a stroke sensor, the magnetic ring is used for penetrating through the stroke sensor, and the magnetic ring can be driven by a servo system and a lead screw assembly to move. When the magnetic ring moves, the stroke sensor can detect the stroke distance of the magnetic ring. In the moving process of the magnetic ring, the servo system transmits an output magnetic ring stroke distance to a computer in real time, the stroke sensor transmits the detected magnetic ring stroke distance to the computer in real time, and the magnetic ring stroke distance output by the servo system and the magnetic ring stroke distance detected by the stroke sensor are compared on the computer to judge whether the stroke sensor is qualified or not. The stroke sensor can be detected fast and effectively so that the stroke sensor leaving a factory can be qualified, therefore, security accidents due to the fact that an unqualified stroke sensor is used in a coal mine are avoided, and detection efficiency and detection precision are high.
