This utility model provides a zero-point exchange device for a four-axis machine tool, including a four-axis machine tool and a loading machine. The four-axis machine tool and the loading machine are signal-connected. The loading machine is horizontally positioned and fixed to the front of the four-axis machine tool. The loading machine has a frame that can be fixed to the ground. Two horizontally sliding moving components are mounted on the frame. Each moving component has a tray that can slide back and forth. A rotatable zero-point exchange platform is mounted on the tray. The four-axis machine tool has a processing table that can dock with the tray. The processing table has a rotating mechanism that docks with and drives the zero-point exchange platform. The loading machine is designed with two moving components, each equipped with a tray and a zero-point exchange platform. By alternating the use of the two trays, a mode of simultaneous processing and loading can be achieved, significantly reducing machine tool downtime, improving production efficiency, and reducing the labor intensity of operators.
