摘要
本设计主要是依据设计要求,根据机械制图基本原理和机械设计基本原理对应用于重型数控龙门铣床的侧铣头进行结构设计,使得该侧铣头能够在 X向和Z向两个方向上进行铣削运动。本设计主要分为四部分:
第一部分是根据设计的要求进行总体方案设计,即对侧铣头的结构进行总体设计。这部分主要包括主运动方式以及伺服进给运动的确定。
第二部分是基于机械设计基本原理,对设计中的伺服进给运动和主运动系统的机械部分进行设计计算。主要包括滚珠丝杠,主轴电机,进给电机的选型,计算和验证,同步带和皮带轮的设计计算。
第三部分是根据机械制图的基本原理,应用绘图软件进行二维设计,生成三张二维装配图纸和一张二维零件图纸。
第四部分是在完成二维设计图纸的基础上,采用SOLIDWORKS软件对零件进行三维建模,并将所有建模零件进行组装生成三维装配体; 在此基础上,使用该软件完成一个三维动画,以显示组件的内部结构和运动。

ABSTRACT
The design is mainly to design the profile cutter head structural of a heavy numerically controlled planomiller according as the rationale of mechanism design and theory of machines on the bases of design specification. The design is mainly divided into four parts:
The first part is a content of total project design of the profile cutter head Structure according as design specification, including confirming the manner of the main motion and the servo feed 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 choose the type, the calculation and the verification of the ball screw, the principal axis electromotor and the feed electromotor, 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 drawings and one detail drawings using CAXA software according to the rationale of theory of machines.
The finally part is to model the parts of the profile cutter head, and create three dimensional drawings using SOLIDWORKS software according to two dimensional drawings designed in the third part;The following is to create a three-dimensional animation to show the inside structure of the three-dimensional assembly drawing and the motion manner using the software on the bases of the three-dimensional assembly drawing.
Key Words:Heavy numerically controlled planomiller;The profile cutter head;Structural design;two dimensional design;three dimensional modeling
