高精度孔距加工保障技术

摘要

A kind of high precision hole spacing correction and positioning fixture was introduced.The structure,principle and using method of this fixture were expounds.The positioning error analysis was proceeded.The superiority of the fixture is proved by practice.The problem that mounting hole position size accuracy requirements of the function accessories fixed on the front end surface of the big,heavy floor-type milling and boring machine ram is much high is solved.%介绍一种高精度孔距校正定位夹具,阐述了夹具的结构、原理和使用方法,进行了定位误差分析.实际使用结果证明了该夹具的优越性,解决了大、重型落地铣镗床滑枕前端面上功能附件安装孔位置尺寸精度要求较高的难题.
