Abstract
The invention relates to a steel pipe drifter used for detecting the inner diameter, straightness, roundness, and inner burr removal quality of a steel pipe, and a method for realizing concentricity of the steel pipe and a drift diameter head. The steel pipe drifter includes a pipe storing rack, a steel pipe conveyor roll table, a pipe inverter, a probe, the drift diameter head, a lifting platform, an operation platform and a pinch roll. The steel pipe drifter is characterized in that a steel pipe clamping mechanism is arranged on the lifting platform, and a guide wheel for avoiding the gravity center of the drift diameter head from moving downwards is arranged at the lower part of the drift diameter head; the lifting platform and the steel pipe clamping mechanism adjust the center line of the steel pipe, and the guide wheel supports the drift diameter head, so that the center of the drift diameter head and the center of the steel pipe still keep on one straight line during the detection process. The steel pipe drifter can prevent the gravity center of the drift diameter head from moving downwards when the drift diameter head enters the steel pipe detection process, keep the drift diameter head to always move at the center of the steel pipe, and ensure the detection result accuracy.
