This utility model relates to the field of tool magazine technology, and more particularly to a heavy-duty vertical lathe tool magazine, including a rotating shaft, a tool disc, and a driving component. The tool disc is concentrically mounted on the rotating shaft, and the driving component drives the tool disc to rotate. The tool disc includes a disc-shaped tool holder with multiple grooves for mounting tools. Support seats are provided on both sides of the grooves, and a buffer structure is provided between the support seats and the tool holder.
