[0002] A drilling machine refers to a machine tool that mainly uses a drill to make holes on a workpiece. Usually, the rotation of the drill bit is the main motion, and the axial movement of the drill bit is the feed motion. The drilling machine has a simple structure and relatively low processing accuracy. It can drill through holes and blind holes. By replacing special tools, it can expand, countersink, ream holes, or perform tapping and other processing. During the processing, the workpiece does not move, the tool moves, aligns the center of the tool with the center of the hole, and rotates the tool (main motion). The characteristics of a drilling machine are that the workpiece is fixed, the tool rotates, and feeds along the spindle direction. The operation can be manual or motorized.

[0003] As a special processing equipment for H-shaped steel, channel steel and box-type structure for steel structure, 3D CNC drilling machine is recognized by more and more manufacturers due to its automation, flexibility and high efficiency. It is widely used in construction, bridges, towers, masts and grid industries. The existing 3D drilling machine for drilling H-steel is too large, which takes up a lot of money when users purchase it, is inconvenient to transport and carry, and the operation of clamping, positioning and feeding the huge workpiece is cumbersome and difficult, resulting in low work efficiency.
