根据大型两轴跟踪测量系统的使用要求,研制了机电式700°转动范围的旋转轴用限位机构,经理论分析和试验验证,该机构工作可靠,很好地解决了旋转轴回转零点的第一次通过和第二次限位问题,机构可适时为设备主控系统提供旋转轴当前位置和到位信息,结构设计巧妙、紧凑,完全可以满足大型高精度光学仪器的使用要求。
According to the requirements of the large two-axis tracking measurement system, the limit mechanism for rotary shaft with 700 ° rotating range is developed. The theoretical analysis and experimental verification show that the mechanism works reliably and solves the problem of Once passed and the second limit problem, the agency can timely provide the main control system for the rotating shaft current position and information, structural design ingenious, compact, fully meet the requirements of large-scale high-precision optical instruments.
