柴油机机体三面半精镗组合机床
总体及左主轴箱设计
摘要:柴油机机体为大批量生产的零件,为了提高其生产效率,满足被加工零件的精度要求,保证加工性能稳定,本课题设计了一台用于ZH1135柴油机机体三面半精镗的组合机床。设计内容主要分为总体设计和左主轴箱设计两部分。总体设计包括机床配置型式的确定、结构方案的选择以及“三图一卡”的绘制。左主轴箱设计包括绘制多轴箱设计原始依据图、确定主轴和齿轮;完成动力计算、设计传动系统;绘制多轴箱装配图和零件补充加工图。机床采用卧式三面加工的方案,加工和装配的工艺性好,零件装夹方便。主轴箱选用的是通用主轴箱。设计过程中尽量采用了标准零部件,设计出的组合机床结构简单,操作方便,加工精度高,减轻了劳动强度,提高了加工效率,具有较好的经济性和适用性。

Design of the overall and Left Headstock of Modular Machine Tool for boring Holes on Three-Side of the body of Diesel Engine
Abstract: The cylinder block of diesel is made for large quantities of mass production. In order to enhance the production efficiency and to meet the precision of ponents processed and the precision stability, a modular machine-tool was designed to be used in the ZH1135 diesel engine with three-side boring holes. The focal point of this topic could be divided into two parts: the general design and the left headstock design. The general design includes the confirmation of the modular machine tool, the selecting of the structure plan and the productivity which satisfies the request was figured out. The left headstock design includes drawing the primitive basic chart for the gear box, determine the spindle and the gears, completing the putation, designing the transmission system, drawing the gear box assembly drawing and th
