摘 要 本论文为加工主轴箱箱体右侧十个螺纹底孔的组合钻床的设计。 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。 为使设计符合现代化要求，该组合机床采用PLC控制系统来控制机床的工作，PLC控制是具有功能完善、通用灵活、简单易懂、操作方便和价格便宜等优点，这不仅满足了现代社会对生产的需要同时也体现了人性化设计的要求。 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. 目 录 前言 －－－－－－－－－－－－－－4 1．毕业设计的目的和内容 －－－－－－－－－－－－－－5 1.1通过毕业设计应达到的目的 －－－－－－－－－－－－－－5 1.2毕业设计的有关内容及计算 －－－－－－－－－－－－－－5 2．方案讨论及总体设计 －－－－－－－－－－－－－－6 2.1 组合机床工艺方案的制定 －－－－－－－－－－－－－－6 2.2 切削用量的确定 －－－－－－－－－－－－－－7 2.3 确定切削力、切削转矩、切削功率－－－－－－－－－－－－－－7 2.4 加工工序图 －－－－－－－－－－－－－－8 2.5
