Long-shaft punching and tapping device for numerically-controlled machine tool

The invention relates to a long-shaft punching and tapping device for a numerically-controlled machine tool, and belongs to the technical field of mechanical equipment. The device comprises a workbench; a rotary platform is arranged on the workbench and is rotationally connected with the workbench; multiple fixture assemblies are arranged on the rotary platform; multiple punching assemblies, a fixture correcting assembly and a discharging assembly are sequentially arranged on the periphery of the workbench; the fixture assemblies are used for fixing workpieces; the punching assemblies are usedfor punching the workpieces; the fixture correcting assembly is used for correcting fixtures; and the discharging assembly is used for moving the machined workpieces out of the fixture assemblies fordischarging operation. The machining precision of materials can be effectively improved, the manpower input can be reduced, and the automation degree is high. 本发明涉及一种用于数控机床的长轴打孔攻牙装置，属于机械设备技术领域，包括工作台，所述工作台上设置有转台，转台与工作台可转动连接，所述
