Abstract

An application example of precision photoelectric 2D-turntable for aiming device baseline variation detection is proposed in this paper, the optical measurement method is also expounded and the design scheme of automatic digital photoelectric 2D-turntable with high precision is supported. Because the supporting framework is the key component and the main bearing component of two-dimensional turntable, its strength and stiffness will directly affect the adjustment accuracy and stability property, the variable density topology optimization is applied to optimize the structure of supporting framework. The quality of supporting framework reduces by 20%, the displacement of the center of shafting mass under gravity loads is less than 0.05mm. The experimental results indicate that adjustment error of the photoelectric 2D-turntable is less than 0.05mil, repetitive positioning accuracy is more than 0.01mil which meets the design requirements of high precision adjustment accuracy or stability.
