箱体双面粗镗床总体设计及左主轴箱设计
摘要:为了提高加工效率和质量以及满足拖拉机变速箱体相应粗镗孔的尺寸精度及位置精度的要求,需要设计一台双面粗镗床。
因此我进行了箱体双面粗镗床总体设计及左主轴箱设计。在分析了工件特点的基础上,按组合机床的设计方法和步骤,进行了组合机床的总体设计。绘制了被加工零件的工序图、加工示意图、机床联系尺寸图和生产率计算卡。在此基础上,拟订了主轴箱的传动路线,应用最优化方法布置齿轮,确定传动参数。最后绘制了主轴箱装配图、箱体图、前盖及后盖的补充加工图,进行了轴、齿轮等零件的强度校核。该组合机床机较好地完成了设计要求,大大提高了工作效率。

The Overall Design of Box Two-Side Rough Boring machines And The Left Headstock Design
Abstract:. To improve the efficiency of processing, quality assurance of tractor transmission gear and cylinder block three rough surface corresponding Boring.
Therefore I overall designed a two-sided rough boring machine and left spindle box design.On the base of analyzing the characteristics of theworkpiece,as the methods and procedures of the modular machine tool desgn, I overall designed the two-sided rough boring machine. By the process of drawing,the schematic diagram of machining,the relationship of the machine size and the card of the productivitywere drawn. Then the primitive chart for the design of the left-side spindle boxwas given out. The transmission routewas confirmed and the transmission parameterwas made. The assembly diagram of the spindle boxwas drawn. After arranging the gears,we used the optimized design. The supplement processing diagram of the front side and behind side platewere also made. The intensity of the axises and gearswas checked. The machine can satisfy the requirement of the design and the controlling precisionwaswholly improved.
Keywords: two-side Rough Boring ; spindle box; modular machine tool.
