Technical Field

[0001] The utility model relates to the technical field of numerical control gantry milling machines, in particular to a numerical control gantry milling machine with a structure for preventing waste chips from splashing outwards. Background Art

[0002] A CNC gantry milling machine, also known as a CNC gantry milling machine, is a milling machine with a portal frame and a long horizontal bed. CNC gantry milling machines offer high precision and production efficiency, making them suitable for machining flat and inclined surfaces on large workpieces in batch and mass production. They can also process curved surfaces and some special-shaped parts. A CNC gantry milling machine consists of a base, a worktable, a gantry, and a spindle housing mounted on the gantry. The spindle housing is equipped with a drive spindle, and a milling cutter is mounted at its lower end. The workpiece is placed on the worktable and secured, and the milling cutter moves relative to the worktable to facilitate machining.

[0003] Regarding the above-mentioned related technologies, the inventors found that when using a CNC gantry milling machine to perform fine processing on a workpiece, the milling cutter needs to rotate at a high speed, and the high-speed rotating milling cutter often throws waste chips to the outside of the workbench.

[0013] In a preferred example, the present invention can be further configured as follows: the driving assembly includes a transverse rotating shaft and a reducer driving the rotation thereof, a motor is installed at the end of the reducer, and both ends of the transverse rotating shaft are respectively connected to the driving shaft on the corresponding screw elevator.

[0014] By adopting the above technical solution, the motor drives the reducer to rotate the horizontal shaft, and the horizontal shaft drives the screw on the screw elevator to move in the vertical direction.
