尺寸链分析和计算在产品精度设计中的应用

Application of dimension chain analysis and calculation in product precision design

精度设计是产品设计的最终环节,在满足装配精度和功能要求的前提下,设计出最佳经济精度的零部件是精度设计的目的.尺寸链分析和计算是产品精度设计的重要方法和手段,通过案例分析,运用尺寸链的设计计算和分析方法,阐述产品和零部件的精度设计过程,以保证产品质量,降低加工成本,同时满足互换性要求.

Precision design is the final link of product design. On the premise of meeting the assembly accuracy and functional requirements, the aim of precision design is to design the parts with the best economic precision. Dimension chain analysis and calculation are important methods and means of the product precision design. Through the case analysis, the precision design process of products and parts is expounded by using the design calculation and analysis method of dimension chain, so as to ensure the product quality, reduce the processing cost and meet the requirement of interchangeability.
