加工中心侧洗头结构设计【机械毕业设计含7张CAD图+说明书1.2万字33页,任务书开题报告】.zip

摘要本设计主要是根据设计要求,依据机械设计和机械制图的基本原理对一台重型数控龙门铣床的侧铣头进行结构设计,该侧铣头能够在 X 方向和 Z 方向两个方向上进行铣削运动。本设计主要分三部分: 第一部分是根据设计要求对侧铣头的结构进行总体方案的设计,主要包括伺服进给运动和主运动方式的确定。第二部分是利用机械设计基本原理对设计中伺服进给运动和主运动系统的机械部分的设计计算,主要包括进给电动机、主轴电动机、滚珠丝杠副的选则、计算和校核以及对同步带和带轮进行设计。第三部分是根据所选择设计的主要零件,先进行大体结构设计,之后在此基础之上, 利用机械制图的基本原理,应用 CAXA 电子图版对侧铣头的结构进行二维设计,并生成三张二维装配图纸和一张二维零件图纸。关键字: 重型数控龙门铣床侧铣头结构设计总体方案设计二维设计 Abstract The design is mainly to design the profile cutter head structural ofa heavy numerically controlled plan miller according as the rationale of mechanism design and theory of machines on the bases of design specification. The design is mainly divided into three parts: The first part isa content of total project design of the profile cutter head Structure according as design specification, including confirming the manner of servo feed motion and the main motion. The second part is design of calculations of machine parts of servo feed motion system and the main motion system according as the rationale of mechanism design . Its mainly including chooses the type, the calculation and the verification of the feed electromotor, the principal axis electromotor and the ball screw , and the design of hold-in range and synchronous pulley . The third part is to design the mainly structure firstly on the bases of main parts choosed and designed in the second part, then to design two dimensional drawings , and create three assembly drawing s and one detail drawing s using CAXA software according to the rationale of theory of machines. Keywords : Heavy numerically controlled plan miller, The profile cutter head, Structural design, total project design , two dimensional design 。目录摘要................................................................................................................................
