【技术实现步骤摘要】
本技术涉及一种燃机叶片检测用装置,特别是一种燃机叶片悬挂式检测定位 装直。
技术介绍
在燃机叶片生产出厂前都要经过严格的尺寸检测,以确保部件间的准确配合,满足设计精度,保障后期燃机工作性能。燃机叶片测量时都需要将叶片的叶根固定住,再对叶片实施测量,所以固定时夹持部的定位精度对测量影响至关重要,现有固定装置主要有卧式和立式两种方式;使用卧式时叶根固定住以后叶片整体呈水平状态,由于叶片重心处于夹持部外侧使叶根受到一偏转力,致使叶片偏移,测量不是很精准;使用立式时叶根朝下叶片朝上,在重力影响下夹持叶根时叶片会产生一个向下的位移;上述两种方法在重力影响下都不能对叶根装配时的定位标准面进行高精度定位,而在与夹持部配合时的尺寸公差内产生尺寸偏移,致使测量时的精度不高,还会由于叶根受力的不均衡还会造成压伤;使装配时达不到叶片装机的理论要求。
