Small-diameter tube digital ray imaging clamping type positioning device

The invention provides a small-diameter tube digital ray imaging clamping type positioning device which comprises a clamp assembly and a tube head positioning assembly, the axis of the tube head positioning assembly is parallel to the axis of an X-ray tube, and the clamp assembly is detachably connected with the tube head positioning assembly through a quick connector. The clamp assembly is provided with two chucks used for clamping a small-diameter tube, an X-ray tube is installed on the tube head positioning assembly in a sliding mode, and the radial position of the X-ray tube is changed by adjusting a tube head sliding block. The method can improve the detection efficiency, reduce the labor intensity, effectively control the radiation influence range, effectively reduce the operation steps of field inspection personnel, improve the detection reliability and reduce the risk of foreign matters. 本发明提供了一种小径管数字射线成像夹持式定位装置，包括夹钳组件和管头定位组件，所述管头定位组件轴线与X射线管轴线平行设置，所述夹钳组件通过快速接头与所述管头定位组件可拆卸连接，所述夹钳组件具有两个夹头用以夹持小径管，所述管头定位组
