组合机床主轴箱及夹具设计

摘 要:根据设计任务书的要求,本设计说明书针对连杆大小头双端面铣削组合机床的设计及专用夹具设计进行说明。主要内容包括组合机床工艺方案的制定、组合机床配置型式的选择、组合机床总体设计以及主轴箱设计。
全文主要包括组合铣床的总体设计和主轴箱设计两部分。机床总体设计主要是在选定工艺方案并确定机床配置形式、结构方案基础上确定“三图一卡”，主轴箱设计根据“三图一卡”，整理编绘出主轴箱原始依据图，重点分析传动系统，经过各种方案的比较，最后确定最优方案。此外，为了提高劳动生产率，降低劳动强度，保证加工质量，需设计专用夹具。

Combination Machine Tool Spindle boxes and fixture design
Abstract:According to designs the project deion the request,This design instruction booklet carries on the explanation in view of the connecting rod reducing socket double face milling aggregate machine-tool design and the unit clamp design. Main content including aggregate machine-tool craft plan formulation, aggregate machine-tool configuration choice, aggregate machine-tool system design as well as headstock design.
The full text mainly includes combines the milling machine the system design and the headstock designs two parts. The engine bed system design mainly is in the designation craft plan and the determination engine bed dis form, in the structure plan foundation determined "a three charts card", the headstock design basis "a three charts card", reorganizes the compilation to leave the headstock primitive basis chart, the key analysis transmission system, passes through each kind of plan comparison, finally determines the most superior plan. In addition, in order to enhance the labor productivity, reduces the labor intensity, guaranteed the processing quality, must design the unit clamp.
