Zusammenfassung:The invention relates to the technical field of hollow shaft machining, in particular to a hollow shaft inner hole automatic clamping device which comprises a base, a fixing plate is fixedly mounted on the left side of the upper end of the base, a fixing shaft of a hollow structure is rotatably mounted at the upper end of the fixing plate, and two positioning units arranged left and right are mounted at the upper end of the base. The positioning unit is used for positioning the left and right ends of the hollow shaft, and a plurality of supporting units uniformly arranged in the axial direction are mounted on the part, located on the right side of the fixing plate, of the fixing shaft; according to the inner supporting and fixing device, each step-shaped structure of the step-shaped hollow shaft can be internally supported and fixed, so that the middle of the hollow shaft is prevented from deforming or bending when the step-shaped hollow shaft is machined, meanwhile, the inner supporting and fixing device can
