The invention discloses a detection device for adjusting eccentricity of a
piston rod, and belongs to the technical field of detection equipment. The detection device comprises a detection ring, a detection inner ring, a follow-up rotating track, a moving track, an adjusting
assembly and a monitoring box, the detection inner ring is arranged in the detection ring, the detection inner ring is rotationally connected with the detection ring through a detection arm, the detection ring is rotationally connected with the follow-up rotating track through a follow-up rotating arm, the follow-up rotating track is in sliding connection with the moving track through the moving arm, a
cantilever arm is arranged at the end, away from the moving arm, of the moving track, an adjusting
assembly is arranged at the end, away from the moving track, of the
cantilever arm, a monitoring box is arranged on the
cantilever arm, and the monitoring box is connected with the detecting arm, the follow-up rotating arm, the moving arm and the adjusting
assembly through wires. The detection device has the eccentricity detection and adjustment functions of a conventional
piston rod device.
