This application relates to a tensioning device and a tensioning machine. The tensioning machine includes a tensioning unit and a control unit. The tensioning unit includes a housing, a tensioning rod assembly, and a detection assembly. The tensioning rod assembly has a tensioning head. The tensioning rod assembly can rotate relative to the housing around its own central axis and advance along its own axial direction to engage with the tensioning screw, or it can retract relative to the housing along its axial direction to tension the member to be tensioned. The detection assembly is disposed on the housing and is used to measure the relative position between the tensioning head and the tensioning screw. Based on the measurement result, it sends a measurement signal to the control unit, so that the control unit can control the tensioning head to be coaxially aligned with the tensioning screw based on the measurement signal, and control the tensioning head and the tensioning screw to engage with each other to a preset length, thereby realizing fully automatic alignment and fully automatic tensioning. This not only improves production efficiency and reduces the labor intensity of workers, but also allows the tensioning station to be set as an unmanned operation station, effectively avoiding the risk of personal injury.
