Description

Technical Field

[0001] The utility model relates to the technical field of drilling machines, in particular to a drilling machine for internal combustion engine parts. Background Art

[0002] An internal combustion engine is a kind of power machinery. It is a heat engine that burns fuel inside the machine and converts the heat energy released directly into power. In a broad sense, internal combustion engines include not only reciprocating piston internal combustion engines, rotary piston engines and free piston engines, but also rotary impeller jet engines, but the internal combustion engine usually refers to piston internal combustion engines. The reciprocating piston type is the most common piston internal combustion engine. The piston internal combustion engine mixes fuel and air and burns them in its cylinder. The heat energy released generates high-temperature and high-pressure combustion gas in the cylinder. The expansion of the combustion gas pushes the piston to work, and then the mechanical work is output through the crank-connecting rod mechanism or other mechanisms to drive the driven machine to work. In the production process of internal combustion engine parts, it is necessary to drill the parts.

[0003] However, when processing internal combustion engine parts, some parts need to be drilled with a larger diameter center hole and smaller diameter peripheral holes located outside the center hole. Existing drilling machines need to replace the drill bit when drilling holes of different diameters, resulting in a longer time required for drilling internal combustion engine parts, affecting work efficiency.
