The overall structure is a large machining center machine with a gantry structure framework composed of double columns and a top beam, and there is also a cross beam between the double columns. After retrieval, the patent with the Chinese patent authorization number CN218081725U discloses a multi-axis linkage device for a high-precision numerical control gantry machining center, including a fixed block. The top of the fixed block is fixedly connected with a frame. The frame is provided with a strip-shaped notch. The frame is provided with a plurality of connecting columns at the strip-shaped notch. The top of the frame is fixedly connected with a machining gantry. The top of the machining gantry is provided with a multi-axis linkage device. The outside of the multi-axis linkage device is fixedly connected with a machining device. The top of the frame is fixedly connected with a fixed bin. One side of the top of the fixed bin is rotatably connected with a rotating plate through a rotating shaft. The rotating plate is provided with a torsion spring at the rotating shaft. The inside of the top of the frame is fixedly connected with an electric push rod.
