摘 要：本课题设计一台加工柴油机齿轮室盖的钻镗组合机床，主要完成机床总体和右主轴箱的设计工作。 
根据柴油机齿轮室盖的结构特点、加工部位、尺寸精度、表面粗糙度及生产率等要求，确定该机床为单工位卧式组合机床；为确保加工精度，采用“一面两销”的定位方案；为实现无级调速，安全可靠，选择液压滑台；根据零件的大小及被加工孔的位置确定主轴箱的轮廓尺寸；由加工工艺选择滚珠轴承主轴，通过计算扭矩确定主轴和传动轴的直径；齿轮的模数是通过类比法确定； 齿轮齿数和中间传动轴的位置是由“计算、作图和多次试凑”相结合的办法确定；计算主轴、传动轴的坐标并进行中心距验算，确定部分轴上需采用变位齿轮；轴上的齿轮套、键等零件按轴号选取相应的标准件。 
本课题设计的组合机床采用“一面两销”定位、液动夹紧，一次装夹加工柴油机齿轮室盖三个面上的孔，保证了加工精度，提高了生产效率，减少了工人的劳动强度。而且在设计之中，尽量选用通用件，减少了制造成本，增加了经济效益。 [版权所有：http://think58.com]

The overall and headstock design of drilling and boring modular machine for diesel engine geal chamber manufacture
Abstract: This project is to design a modular machine tool for manufacturing the gear chamber cap of diesel engine. Mainly work is the design of overall and the right headstock. 
According to the request of construction features, processing spot, size precision, surface roughness and productivity that diesel engine gear chamber cap, sets the machine tool for single location horizontal type modular machine tool. In order to guarantee the processing precision, the localization plan use "two sells and a surface". In order to implement the stepless speed regulation, safe is reliable, therefore choice hydraulic pressure sliding table. According the size of components and the position of the hole that is processed to set the overall size of the headstock. Choicing ball bearing spindle by processing craft. The spindle and drive shaft diameter is decided through computation torque. The gear modulus is decided through the correlation method. The gear mentions and the position of intermediate propeller shaft is decided by the means " computation, mapping and tries to collect many times". Calculates the coordinates of the spindle and drive shaft and checking the center distance, determined department spindle must use dislodges the gear. The components of tooth wheel cover, key and so on that in axis select standard letter by the corresponding number.  [资料来源：www.THINK58.com]
The modular machine tool of this project design use “two sells and one surface” to locate , hydraulic press and clamps. In the situation of one clamp, the holes three surface of the diesel engine gear chamber cap, are guaranteed the processing precision, is enhanced the production efficiency, is increased worker's labor intensity. Moreover during the design, the standard parts are selected as far as possible, reduced the production cost and increased the economic efficiency.

Key words: modular machine tool headstock spindle drive shaft gear chamber cap

1 前言 
组合机床是根据工件加工需要，以大量通用部件为基础，配以少量专用部件组成的一种高效率专用机床。目前，组合机床主要用于平面加工和孔加工两类工序。平面加工包括铣平面、锪（刮）平面、车平面；孔加工包括钻、扩、铰、镗孔以及倒角、切槽、攻螺纹、锪沉孔滚压孔等。随着综合自动化的发展，其工艺范围正扩大到车外圆、行星铣削、拉削、推削、磨削、珩磨及抛光、冲压等工序。此外，还可以完成焊接、热处理、自动装配和检测、清洗和零件分类及打印等非切削工作。 
组合机床在汽车、拖拉机、柴油机、电机、仪器仪表、军工及缝纫机、自行车等轻工行业大批大量生产中已经获得广泛的应用；一些中小批量生产是企业，如机床、机车、工程制造业中也已推广应用。组合机床最适宜于加工各种大中型箱体类零件，如汽缸盖、汽缸体、变速箱 [资料来源：THINK58.com]
