文档介绍：数控回转工作台毕业设计说明书
摘要
本次毕业设计的题目是数控回转工作台设计。通过对数控回转工作台的设计,使大学生在步入社会之前,不仅能够设计出数控回转工作台,而且能够掌握机械设计的方法和步骤。本课题研究的主要内容包括:确定数控回转工作台的传动方案;零件设计相关计算与校核;零件图及装配图的绘制等。
对于数控回转工作台的设计,首先,进行总体方案设计,传动方案采用齿轮传动和蜗杆传动;然后进行各零件的设计与校核,蜗杆与轴采用整体式结构;蜗轮与工作台采用螺钉连接;工作台的平衡通过止推轴承来保证;箱体由箱座、箱盖和顶盖组成;最后,对各零件进行装配。
数控机床的圆周进给由回转工作台完成,回转工作台可以与X、Y、Z三个坐标轴联动,从而加工出各种球、圆弧曲面等。回转工作台可以实现精确的自动分度,扩大了数控机床加工范围。目前,数控回转工作台主要用于卧式的镗铣床和加工中心上。

Abstract
The graduation project is the subject of design C rotary worktable. With the NC rotary table design, making the students not only to design C rotary worktable, but be able to master the mechanical design of the methods and procedures before they entered munity. The main content of this research include: determining the transmission scheme C rotary worktable; part design and verification; part drawing and assembly drawing drawing, and so on.
the design of NC rotary worktable, first of all, is the overall design, transmission scheme using a gear drive and worm drive; and then proceed to the design and checking of all parts, worm and shaft with the overall structure; worm gear screw connection with the table; the workbench balanced by the thrust bearing to ensure; box by box seat, cover and top cover, of which the box on the design of the round table and strengthen the tendons; finally, the assembly of various parts
The circumference feed of C machine tool to pleted by the rotary table, the rotary table can be used with the X, Y, and Z three axes linkage, thereby processing a variety of balls, the circular surface, and so on. The rotary table can achieve accurate automatic indexing, C machining range. At present, the NC rotary table is mainly used for horizontal boring and milling machine and machining center.
Keywords: NC rotary worktable, gear, worm, box
