一种高精度直角铣头结构设计及其温升形变检测

摘要

Introduces a high precision right-angle milling head structure,vertical shaft adopts five angular contact bearings,horizontal spindle adopts two angular contact bearings with a deep groove ball bearings,compact structure,rational layout,convenient assembly.By temperature rise and deformation tests,proved that the structure of the right-angle milling head for a long time running condition can be in reasonable temperature rise and small deformation,the structure of right-angle milling head structure has good accuracy retention.%介绍了一种高精度的直角铣头结构,立轴采用5个角接触球轴承,卧轴采用2个角接触球轴承与1个深沟球轴承,结构紧凑、布局合理、装配方便.通过温升及形变检测,证明了此直角铣头结构在长时间运转状态可具有合理的温升及较小形变,具有好的精度保持性.
