This application relates to the field of machine tool component technology, and discloses a tailstock assembly and a machine tool. The tailstock assembly includes a tailstock component, a hook, a guide rail, and a drive assembly. When the tailstock assembly is working, the hydraulic cylinder in the drive assembly is the core power source.
