变速箱箱盖组合钻床设计
摘 要
毕业设计是检验一段学习时期学习效果的重要过程,对于我们每个毕业生来说,它既是一个挑战,更是一个锻炼自己的好机会,所以我们都认真对待,并投入了巨大的热情,付出了艰辛的努力。
本论文为加工变速箱箱盖组合钻床的设计。
根据加工工件的尺寸图和生产要求,合理的拟定设计方案,完成该机床各部件及系统的设计,主要包括加工工序的制定,主轴、刀具的选择,多轴箱和滑台的合理选用,主轴箱内传动系统的设定,夹具的设计,以及制定液压和控制系统。设计过程中,在满足设计要求的同时,应该注意相互间的合理配合,这样才能从整体上把握组合机床的性能和结构。
毕业设计是学生在校学习期间最后一个重要环节,毕业设计旨在培养学生综合运用所学知识进行设计的能力。
本次设计得到了指导老师和同学们的大力帮助,在此表示衷心的感谢。
限于设计者水平和经验有限,再加上时间仓促,难免有疏漏和不妥的地方,敬希广大老师和同学们批评指正。

Box drilling machine design
ABSTRACT
This thesis combination machine for design processing many stalks the box ten screw threads of rights the bore bed.
According to the processing work piece dimensional drawing and the production request, reasonable draws up the design proposal, completes this engine bed various parts and the system design, mainly includes the processing working procedure the formulation, the main axle, the cutting tool choice, the multi-axle-boxes and the sliding table select reasonably, in headstock transmission system hypothesis, jig design, as well as formulation hydraulic pressure and control system. In the design process, while satisfies the design request, should pay attention to mutually the reasonable coordination, like this can grasp the aggregate machine-tool overall the performance and the structure.
For making design to meet the modern request, and reshuffle to match the machine bed to adopt the PLC to control the system to control the revolving of machine bed, PLC control to have the function perfect, in general use and vivid, in brief and easily understand, operation convenience with price cheapness etc. Advantage, this not only satisfied the modern society to demand production also now the request of the humanized design.
