Description
Technical Field
[0001] The utility model relates to the technical field of drilling machines, in particular to a drilling machine for machining castings. Background Art

[0003] In Chinese utility model patent application number: CN202022691516.9, a radial drilling machine for deep processing of castings is disclosed. The radial drilling machine uses a lubricating and squeezing mechanism. When devices such as a slide column and a sleeve support and slide the rocker, during the sliding process, as the sleeve slides up and down, friction will be generated between the inner wall of the sleeve and the outer surface of the slide column. At this time, the lubricating and squeezing mechanism on the surface of the slide column is used to fully lubricate and protect the surface of the slide column to prevent friction damage; the radial drilling machine uses a water sprinkling and flushing mechanism. When the drill bit driving mechanism is processing the workpiece, the water sprinkling and flushing mechanism is used to flush and cool the drill bit surface parts, thereby reducing the temperature of the drill bit surface and ensuring safe processing of the drill bit and the workpiece. However, the drilling machine is not convenient for fixing the workpiece when in use, and cannot ensure the stability of the workpiece when drilling. Moreover, the drilling machine cannot collect the debris generated by drilling when in use, and the debris splashes and is difficult to clean.
