柴油机气缸体三面钻削组合机床总体及后主轴箱设计
摘要:课题来源于江动集团,ZH1105W型柴油机是该集团大批量生产的产品之一。本课题设计的是柴油机气缸体三面钻削组合机床,用于加工被加工零件左、右、后三个面上的31个光孔。
该机床设计的重点是总体设计和后主轴箱设计两部分。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。后主轴箱设计包括绘制主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。在进行组合机床总体设计时,首先应根据柴油机气缸体后侧面上钻6个孔的位置精度、表面粗糙度及其他技术要求,拟订总体方案。主轴箱是需要大量生产的零件。在多轴箱设计中,设计的主要思路是把原有的多道工序的单孔加工改为多孔同时加工,这样设计主要是为了解决由多次装夹引起的定位误差问题,保证了孔的位置精度。
本组合机床效率高,成本低,加工精度高,操作使用方便,减轻了工人的劳动强度,提高了劳动生产率。

Design of General and Rear Headstock of Modular Machine Tool for Drilling Holes on Three-Side of Cylinder Body
Abstract: This es from Jianghuai power group, Model ZH1105W Diesel is the one of the products of mass production. This issue is the design of modular machine tool surface for drilling holes on three-side of cylinder diesel,The modular machine tool is used to drill 31 holes, which are on the left, right and rear surface.
The important point of this topic is the system design and the rear headstock design. The system design includes the definite of the modular machine tool, the selecting of the structure plan and the drawing of “three pictures and one card”. The rear headstock design includes drawing the primitive basic chart for the headstock, determining the spindle and the gears, completing the putation, designing the transmission system, drawing the headstock assembly drawing and the part processing modular machine to system design,first under-cylinder diesel engine rear surface drilling 6 holes accuracy of the location, surface roughness, and other technical requirements,develop overall headstock is a product which needs mass production. Headstock in the design, the design is the main ideas from the original multi-channel process to the processing of porous single hole while processing, this design is mainly to solve the fixture by the time the positioning error caused the problems to ensure the accuracy of the location of
