Positioning device for X-ray detection equipment

The invention discloses a positioning device for X0ray detection equipment, and relates to the technical field of the ray flaw detection. When performing detection on a steel tube, the welding line ofthe steel tube or the steel tube internal structure with bad roundness can be effectively detected from different angles, thereby preventing the defect from missing detection due to the angle problem, and the detection precision cannot be affected; the steel tube is driven through driving mechanisms on support mechanism arranged at two ends, thereby conveniently controlling and driving the rotation and revolving of the steel tube; the convenience of the driving is improved, and a motor can be effectively protected in comparison with a way of using a positive-negative motor; and meanwhile, theinfluence on the positive-negative motor by the inertia force of the steel tube is reduced; the clutch control is performed by adopting an electromagnetic tensioning way, and the control is convenient and simple. 本发明公开了一种用于X射
