Description

Technical Field

[0001] The utility model relates to the technical field of drilling machines, and more specifically, to a drilling machine for processing metal workpieces. Background Art

[0002] A drilling machine is a mechanical equipment used to process metal, wood or other materials. It is mainly used for drilling or tapping. It is widely used in manufacturing and processing fields. 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 or tap. During the processing, the workpiece does not move, the tool moves, aligns the tool center with the hole center, and rotates (main motion). The characteristic of a drilling machine is that the workpiece is fixed and the tool rotates.

[0003] In the existing technology, the position of the current drilling machine fixture is fixed, which makes it inconvenient to adjust the position of the fixture on the drilling machine. At the same time, a large amount of debris will be generated during the drilling process. These debris will accumulate on the workbench and affect the subsequent drilling work. At the same time, when the existing drill bit is in use, some of the debris generated by drilling will splash into the air, which not only pollutes the environment but also easily injures people.
