[0002] Gantry CNC machining center is an automated machine tool controlled by a program. The control system logic processes the program specified by the control code or other symbolic instructions, which are decoded by the computer to enable the machine tool to perform the specified actions and cut the rough material into semi-finished products, finished products or parts through the tool.

[0003] Before a workpiece needs to be processed by a gantry CNC machining center, the workpiece needs to be moved to a workbench of the gantry CNC machining center. The existing method usually moves the workpiece by a gantry crane.

[0004] However, the gantry crane needs to be installed in advance to transport the workpiece. Every time a workpiece is processed, it needs to be hoisted by the gantry crane, which is troublesome and cumbersome. The existing gantry CNC machining center does not have a loading structure, which reduces work efficiency.

[0005] Moreover, the loading structure of the existing gantry CNC machine tool still needs the help of tools when moving the workpiece to the loading device. The existing loading device cannot move to the position of the workpiece to transport the workpiece. The workpiece needs to be transported to the loading device by tools before loading can be carried out. Utility Model Content
