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。 copyright paper51.com 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。 http://www.paper51.com 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。 内容来自www.paper51.com paper51.com ABSTRACT paper51.com This thesis combination machine for design processing manystalks the box ten screw threads of rights the bore bed. 内容来自论文无忧网 www.paper51.com
According to the processing work piece dimensional drawing andthe production request, reasonable draws up the design proposal, completes thisengine bed various parts and the system design, mainly includes the processingworking procedure the formulation, the main axle, the cutting tool choice, themulti-axle-boxes and the sliding table select reasonably, in headstocktransmission system hypothesis, jig design, as well as formulation hydraulicpressure and control system. In the design process, while satisfies the designrequest, should pay attention to mutually the reasonable coordination, likethis can grasp the aggregate machine-tool overall the performance and thestructure. 内容来自论文无忧网 www.paper51.com For making design to meet the modern request, and reshuffle tomatch the machine bed to adopt the PLC to control the system to control therevolving of machine bed, PLC control to have the function perfect, in generaluse and vivid, in brief and easily understand, operation convenience with pricecheapness etc. Advantage, this not only satisfied the modern society to demandproduction also now the request of the humanized design. 内容来自www.paper51.com 目 录 http://www.paper51.com 前言 --------------4 内容来自www.paper51.com 1.毕业设计的目的和内容 --------------5 http://www.paper51.com 1.1通过毕业设计应达到的目的 --------------5 copyright paper51.com
