【摘要】 为了实现对Capto刀柄关键尺寸的精密测量,在详细分析了ISO标准的基础上,确定了被测参数,设计了Capto刀柄测量系统。根据约束空间自由度的思想确定了定位方案,通过刀柄自重实现轴向定位,通过三个支承钉的合理配置实现径向定位,通过严格控制测量环规腔体的尺寸实现周向定位。利用研制出的测量系统对Capto刀柄进行了等精度测量,测量结果符合标准规定的精度要求。研究表明该测量系统的定位方式是可行的,能够满足对Capto刀柄关键尺寸的测量需求。更多还原

【Abstract】 In order to accomplish accurate measurement for Capto shank’s key dimensions, based on analyzing Standard ISO detailedly measurement parameters were determined and measurement system for Capto shank was designed. Positioning scheme was decided according to the idea about restraining the degrees of freedom in space, axial positioning was achieved by shank’s own weight, radial positioning was achieved by the rational configuration of three supporting nails, and circumferential positioning was achieved by controlling ring gauge’s cavity dimension strictly. Measurement for Capto shank with equal precision was done by using the developed measurement system, measurement results accorded with the accuracy requirement stipulated by ISO. Research shows that positioning method of the measurement system is feasible and can meet the demand of measurement for Capto shank’s key dimensions.更多还原
