摘　　要：机器设备功能的实现,除零部件本身的生产加工精度和质量起着决定因素外,产品的装配精度、装配质量也是重要因素,是实现产品功能的最终环节。实际生产中,许多机械及其零部件因装配精度不合格而无法使用。对机械零部件装配中存在的困难进行分析,提出用修配法通过对装配尺寸链的计算而保证机械产品装配精度的措施。In addition to processing precision and quality of the production parts,factors of assembly precision and the product assembly quality are also very important for realizing the function of machine,which would be the final link of product function. In the actual production,many machines and their parts cannot be used because of the poor assembly accuracy. In this paper,difficulties existing in the assembly of mechanical components are analyzed,and some measures to ensure the assembly accuracy of mechanical products by the repair method and calculation of assembly dimension chains are then put forward.
