摘要
光学分度头作为角度检测的重要精密光学仪器之一,用于产品检测时人们往往在一定角度范围内选择特定点进行测量,通过测试数据分析产品是否达到使用要求。在测试过程中,需要人工将手柄旋转到这些点,由于光学分度头精度高,人工旋转时容易旋过,反向间隙处理不好会影响测试精度,使用时人工费时费力,批量生产中往往无法确保产品的按时交付.为解决光学分度头手工旋转效率问题,有必要对光学分度头进行数字化改造。通过分析优化最终选择数控系统加伺服驱动的方式对光学分度头进行改造,并对伺服驱动器、电动机和机械连接机构等进行较为详细透彻的设计。通过数控程序实现了光学分度头的自动旋转,达到了降低制造成本,提高经济效益的目的。
The optical dividing head as one of the important angle detection precision optical instruments for product testing,people tend to choose a certain point in a certain range of measurement.Through the test data analysis,we know whether the product meets the requirements.In the test process,it is required to rotate the handle to the point.Due to the high precision of optical indexing head,manual rotation is easy to spin off.The reverse gap processing will affect the accuracy of the test,the use of manual labor and time consuming,and the mass production is often unable to ensure the timely delivery of products.In order to solve the problem of manual rotation efficiency of optical style,it is necessary to transform the optical indexing head.Designers through the analysis of the optimization of the most comprehensive selection of CNC system and servo driven approach to the optical indexing head,and servo drives,motors,mechanical connections,and so on.Through the numerical control program,the automatic rotation of the optical indexing head is realized,which can reduce the manufacturing cost and improve the economic benefit.
