摘　　要：针对通径机对不同直径的钢管进行通径检测时,存在中心线对中问题,设计了钢管通径自动调心机。其核心部件由曲柄滑块机构及平行四边形机构组成。通过液压缸或丝杠升降机运动获取动力,使托举钢管的V型架能上下运动,实现钢管自动对中。通过运动分析,得到了钢管直径、丝杠行程和V型架调节高度之间的关系式。为实现不同直径钢管的自动对中从而提高钢管通径效率提供了理论基础。It was difficult to locate steel pipes centre lines, when using a pipe through inner diame- ter machine to check internal diameter of different diameter steel tube. An automatic centering mechanism is designed. The slider-crank mechanism and parallelogram mechanism mechanical structure is the central body of the machine. The movement of hydraulic cylinder and screw eleva- tor can lift the V shaped rack up and down to locate steel pipes centre lines. Through the kinemat- ic analysis,the links between the steel pipe diameter,the screw-stroke and the adjustable height of the V shaped rack can be obtained, which provides the theoretic foundation for raising productivi- ty to check internal diameter of different diameter steel tube.
