2010 “万向节滑动叉”端面铣削组合机床设计(含全套毕业说明书和机械CAD图纸).docx

2.2 主轴组件的布局 摘 要 组合机床，是由大量的通用部件和少量专用部件组成的工序集中的高效率机床。其特点有：结构紧凑、工作质量可靠、设计和制造周期短、投资少、经济效果好、生产率高等。 本次设计首先针对所要加工的零件入手，对机床进行总体方案设计，进而确定机床的总体布局，随后，对主轴组件进行设计。在设计主轴组件时，以主轴为线索，在满足刚度、精度等要求下，完成其它（如轴承、轴向调节机构、锁紧机构等）所有零件的设计。 关键词：万向节滑动叉；组合机床；主轴；轴承； ABSTRACT Modular Machine, by the large number of common parts and a small number of specialized components of the process focused efficient machine. Its features include : compact, reliable quality, design and manufacturing cycle shorter, less investment and economic effects, and higher productivity . This design, first in response to the processing of parts, the paper machine for the overall program design, which will determine the overall layout of the machine. Subsequently, the spindle components of the design. Spindle components in the design, a spindle for clues to meet stiffness and precision requirements, the completion of the other (eg, bearings, Axial adjustment, locking, etc.) all parts of the design.
