内燃机机体油道孔组合深孔钻设计

The Design of the Assembled Gun Drilling in the Oil Duct of the Internal-combustion Engine

介绍了内燃机机体油道孔组合深孔钻设计。重点对专用的滑套式液压动力头的结构设计予以阐述。在生产实际中,该机床运行可靠,结构简单,制造周期短,操纵维护方便。

The design of the assembled gun drilling in the oil duct of the internal-combustion engine was introduced. The design of the hydraulic-pressure power unit in the style of sliding sleeve was analyzed. In the real producing period, this machine tool runs reliably. It has simple design and short producing period, and is easy to operate and maintain.
