Description

Technical Field

[0001] The utility model relates to the technical field of hardware drilling machines, in particular to a hardware drilling machine which is convenient for adjusting the drilling angle. Background Art

[0002] A hardware drilling machine is required for hardware processing. A drilling machine refers to a machine tool that mainly uses a drill bit to process 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 characteristic of a drilling machine is that the workpiece is fixed and the tool rotates.

[0003] At present, when processing hardware on the market, a hardware drilling machine is needed to drill holes in the hardware. In actual use, when a hardware drilling machine drills holes in hardware, due to the different shapes of hardware workpieces, when the outside of the hardware workpiece is inclined, when the hardware drilling machine drills holes in the outside of the hardware workpiece, it is very easy for the outside of the hardware workpiece to be not perpendicular to the drill bit of the hardware drilling machine, thereby increasing the defective rate of subsequent hardware workpiece drilling.
