一种检测槽形抛物面聚光器安装同轴度误差的方法
摘要：
本发明公开一种检测槽形抛物面聚光器安装同轴度误差的方法。该检测方法是平行于聚光器驱动轴线安装固定一个光学十字瞄准仪，在聚光器轴支撑附近垂直于聚光器轴线安装标尺，以聚光器轴线为旋转轴线旋转调整标尺直到光学十字瞄准仪的十字线对准标尺上的刻线读数，驱动聚光器驱动轴带动光学十字瞄准仪旋转180°，通过光学十字瞄准仪十字线对准标尺上的刻线读数，从而根据这两次的读数差值测量出聚光器轴线安装的同轴度误差。该检测方法能够方便、有效、可靠地检测出槽形抛物面聚光器超长尺寸多段中心轴的同轴度误差，且不受仪器安装误差的影响。
摘要（英）：

The invention discloses a method for detecting the coaxiality error in the installation of a groove-shaped parabolic condenser. The detection method is characterized in that an optical cross collimator parallel to the driving axis of the condenser is fixedly arranged; a ruler vertical to the axis of the condenser is arranged near a condenser shaft support; and the ruler is rotated and adjusted byusing the axis of the condenser as the rotating axis till the cross line of the optical cross collimator is aligned to the mark reading on the ruler, a driving shaft of the condenser is driven to drive the optical cross collimator to rotate by 180 degrees, and the cross line of the optical cross collimator is aligned to the mark reading on the ruler, therefore, the coaxiality error in the installation of the axis of the condenser is measured according to the difference value of the two readings. According to the detection method, the coaxiality error of an overlong multi-section central shaftof the groove-shaped parabolic condenser can be conveniently, effectively and reliably detected without being influenced by the installation error of instruments.
