[0002] CNC drilling machines are mainly used for drilling, expanding, reaming, tapping and other processing. It is a digitally controlled hole processing machine tool mainly for drilling. Due to the development of machining centers, most CNC drilling machines have been replaced by machining centers. In the automotive, locomotive, shipbuilding, aerospace, and engineering machinery industries; especially for the drilling of various large parts with porous systems such as super-long stacked plates, longitudinal beams, structural steel, and tubular parts, it is the first choice.

[0003] At present, a CNC drilling machine with transmission is usually provided with a column on the top of the base, and a drilling rig is fixedly connected to the top of the column. Since the height of the column is fixed, such a setting results in a very short drilling stroke of the drilling rig, making it inconvenient for workers to drill deeper holes in the workpiece, which has certain limitations when used.

[0004] Therefore, it is necessary to transform the transmission CNC drilling machine to effectively prevent the problem that the drilling stroke of the drilling rig is very short, making it inconvenient for workers to drill deeper holes in the workpiece. Utility Model Content

[0005] In order to solve the problems raised in the above-mentioned background technology, the purpose of the utility model is to provide a CNC drilling machine, which has the advantage of improving the drilling stroke of the drill rig and making it convenient for the staff to use it, and solves the problem that the drilling stroke of the drill rig is very short, making it inconvenient for the staff to drill deeper holes in the workpiece.

[0006] The utility model provides the following technical solution: a CNC drilling machine comprises a base, a placing rack is fixedly connected to the top of the placing rack, a control panel is fixedly connected to the top of the control panel, a protective box is fixedly connected to the right side of the control panel, an electric telescopic rod is fixedly connected to the inside of the protective box, and the electric telescopic rod is electrically connected to the control panel, a drilling machine is fixedly connected to the output end of the electric telescopic rod, and the drilling machine is electrically connected to the control panel, a support column is fixedly connected to the center of the base, a three-jaw chuck is fixedly connected to the top of the support column, and the three-jaw chuck is arranged to correspond to the drilling machine.

[0007] The beneficial effects of the utility model are as follows:

[0008] 1. The utility model can grasp and fix the workpiece through the three-jaw chuck, and can control the electric telescopic rod to drive the drilling machine to move downward through the control panel, and the workpiece can be drilled through the drilling machine, thereby increasing the drilling stroke of the drilling machine.

[0009] 2. The utility model can prevent the debris generated by the drilling machine processing the workpiece from splashing everywhere through the provision of the dust baffle, and has a certain dust-proof ability. BRIEF DESCRIPTION OF THE DRAWINGS
