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，其中箱体上设计了圆台和加强筋；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数控镗床和铣床。随着数控技术的应用越来越广泛，数控回转工作台的应用已成为历史的必然。5630

Design of NC rotary worktable
Abstract：The graduation project is the subject of design of CNC rotary worktable. NC rotary table on the design, so that before the students entered the community, not only to design a CNC rotary worktable, and can master the mechanical design of the methods and procedures. The main content of this research include: determining the transmission scheme of CNC rotary worktable; driving force calculation and other calculations; part design and verification; part and three-dimensional mapping model; assembly drawing and motion simulation.
NC rotary worktable for the design, first of all, the overall design, use of transmission scheme and worm gear drive; then each part of the design and verification, the whole worm and shaft structure; worm screw connection with the worktable; Balance worktable by thrust bearings to ensure; box from the box seat, lid and cover, of which the box on the design of the round table and strengthen the tendons; Finally, the parts for assembly.
The circumference of CNC rotary worktable by the completion of the feed, rotary worktable with X, Y, Z three axis coordinates to be processed into a variety of balls, such as circular surface. Precision rotary worktable can realize automatic indexing, and expand the range of CNC machining. Currently, the NC rotary table CNC boring and milling machines are mainly used. With more and more widespread application of CNC technology, CNC rotary worktable applications has become a historical necessity.
Keywords: NC rotary worktable; gear; worm; box; modeling
