The gantry milling machine is a commonly used equipment in machining. The gantry of the traditional gantry milling machine is a standard part, usually including a cross beam and two columns. A plurality of threaded mounting holes are distributed in a rectangular shape at both ends of the bottom of the cross beam. The two columns are mounted on the cross beam by bolts in cooperation with the threaded mounting holes. The width of the gantry is not adjustable, and its restricted machining stroke is fixed. If the size of the workpiece to be machined exceeds this restricted machining stroke, the entire gantry needs to be replaced with a gantry with a larger machining stroke, resulting in an increase in the machining and manufacturing cost of the workpiece, which is not conducive to the development of the enterprise.

Installation grooves and multiple groups of first mounting holes and second mounting holes arranged around the installation grooves are provided at both ends of the cross beam. The multiple groups of first mounting holes are arranged at intervals horizontally, and the multiple groups of second mounting holes are arranged at intervals vertically. The first mounting holes and the second mounting holes can form a rectangular mounting position for mounting the columns; multiple groups of first extension holes are provided at both ends of the cross beam and on the extension blocks, and the multiple groups of first extension holes are arranged at intervals horizontally. A first gasket is provided in the installation groove. Multiple groups of second extension holes are provided on both the first gasket and the extension blocks, and the multiple groups of second extension holes are arranged at intervals vertically. The first extension holes and the second extension holes can form a rectangular extended mounting position for mounting the columns; the two columns are respectively detachably connected to the mounting position or the extended mounting position.
[0006] Further, six groups of the first mounting holes are provided. The six groups of first mounting holes are arranged at intervals in two rows on the cross beam, and the distance between adjacent two groups of first mounting holes is D; the multiple groups of second extension holes are arranged in two columns on the first gasket, and the distance between the two columns of second extension holes is D; the extension blocks include a first extension block and a second extension block, and the widths of the first extension block and the second extension block are D and 2D respectively; the first extension holes on the cross beam coincide with the positions of some of the first mounting holes.
[0007] Furthermore, a second gasket is fixed at both ends of the beam, and a plurality of first connecting holes are provided on the second gasket; a plurality of second connecting holes corresponding to the positions and sizes of the first connecting holes are provided on the end face of the extension block, and a plurality of connecting grooves connected to the second connecting holes are provided circumferentially on the extension block; the extension block can be fixed to the two ends of the beam by screws in cooperation with the second connecting holes and the first connecting holes.
[0008] Compared with the prior art, the utility model has the following beneficial technical effects:
[0009] The utility model can widen the width of the crossbeam by adding extension blocks at both ends of the crossbeam, thereby increasing the processing stroke of the gantry, so that it can process larger-sized workpieces. Compared with the gantry with non-adjustable width in the prior art, the utility model can realize the processing of large-sized workpieces exceeding the original limited processing stroke while saving costs.
