现有光学定心磨边机尚不具备在线测量口径参数的功能,而手工修磨易导致定位平台垂直度超差,光学元件的光学定心对中心偏、凹面口径精度的控制尤为重要.设计改造了一种光学定心可视化在线检测装置,通过增加在线测量口径及拖边进刀量计算功能,在定心磨边设备上设计安装了可视化检测装置,解决采用手工修改控制方式引起元件表面光洁度受损、定位平台的垂直度超差、口径超差问题.实测结果表明,零件偏心、垂直度与凹面口径测量精度达 0.01 mm,均满足光学加工实际应用要求.通过可视化光学定心检测系统在线测量,可一次装夹完成零件外圆与定位平台加工,提高光学元件凹面口径精度,减少手工修磨工序,提升产品合格率及加工效率,为光学加工的定心技术提供可靠、高效的解决方案.
Optical Centering Online Testing System Based on Visualization
The current centering and edge grinding equipment did not have the ability to get the parameters online,and manual grinding could cause the verticality of the positioning platform to exceed the tolerance.Therefore,it is particularly important to control the center deviation of the optical components and the concave aperture accuracy after optical centering.This paper designed a visual online testing device for centering.By adding the functions of online measurement of caliber and calculation of dragging edge feed amount,a visual detection device was designed and installed on the equipment to solve the problems of damaged surface smoothness of components,excessive verticality and caliber of the positioning platform caused by manual modifications.The actual test results show that the measurement accuracy of eccentricity,verticality,and concave diameter of the parts reaches 0.01 mm,which meets the practical application requirements of optical processing.By the visual online testing,the machining of the outer circle and positioning platform of the parts can be completed in one clamping process,upgraded the concave aperture accuracy of the components,reduced the manual grinding processes,and improved the product qualification rate and machining efficiency.A reliable and efficient solution for the centering technology of optical processing was provided.
