立臥式雙面44軸組合鉆床后主軸箱設計
摘 要
本文主要是針對立臥式雙面44軸組合鉆床后主軸箱的設計進行闡述。這次設計是在通過查閱機械設計基礎、機械設計手冊、組合機床設計簡明手冊、機械設計、機械制圖、機械制造工藝學、與畢業(yè)設計指導手冊等之后完成的。通過這次設計可以了解發(fā)動機機體大批量生產(chǎn)流水線中組合機床的原理、結(jié)構(gòu)、工藝水平、分析使用現(xiàn)狀及存在的問題，以及分析三缸機體的結(jié)構(gòu)、工藝流程及設計要求。本文主要包括緒論、加工工藝分析、多軸箱的基本結(jié)構(gòu)及表達方式、多軸箱的設計、組合機床多軸箱CAD系統(tǒng)等幾個部分。重點放在主軸箱的設計部分，包括繪制多軸箱設計原始依據(jù)圖、主軸、齒輪的確定及動力計算、繪制多軸箱總圖及零件圖、多軸箱的傳動設計。
設計組合鉆床的目的在于實現(xiàn)多孔一次定位，避免重復定位所產(chǎn)生的定位誤差，提高被加工孔的位置精度。同時也保證了被加工孔的同軸度。

Author:YangZhifu
Tutor:JiaBaihe
Abstrac
This paper is to elaborate on the design of the headstock after the 44-axis, horizontal double-sided Combination Drilling. The design is a concise manual by consulting the basis of mechanical design, mechanical design manual, machine tool design, mechanical design, mechanical drawing, mechanical manufacturing technology, and graduated from design guidance manuals completed after. With this design you can understand the combination of machine tools in the engine block in the mass production assembly line principle, structure, technological level, analysis of the use of current situation and existing problems, and to analyze the the triplex body structure, process and design requirements. In this paper, including introduction, process analysis, several parts of the basic structure and expression of multi-axle box, multi-axle box design, machine tool, multi-axle box CAD system, etc.. Focus on the design portion of the spindle box, including the preparation of multi-axle box design to determine the dynamic calculation of the Figure the original basis, spindle, gear, and to draw multi-axle box diagram and parts diagram, multi-axle box transmission design.
The purpose of the design Combination Drilling is achieve porous positioning, to avoid the repeatability of positioning of the positioning errors, improve the accuracy of the location of the hole to be machined. But also to ensure the concentricity of the holes to be machined.
