Gantry machining center beam guide rail structure

The utility model discloses a cross beam guide rail structure of a gantry machining center, which belongs to the technical field of gantry machining centers and comprises a cross beam, a ram is arranged on the outer side of the cross beam, a lubricating component is mounted at the top of the ram, and a movable connecting device is mounted on the inner side of the cross beam. An illumination extending device is mounted on the movable connecting device and located on the outer side of the cross beam, and a shielding cleaning device is arranged on the outer side of the lubricating assembly. Through the arrangement of the movable connecting device and the illumination extension device, a worker can adjust the positions of structures such as the two sliding rods by operating the gear motor as required, so that the ram and the sliding block can continue to move along the two sliding rods after being separated from the cross beam, the moving range of the ram is expanded, and the working efficiency is improved.
