Structure Design of High-precision Small Theodolite Shaft Locking Mechanism
With the increasing demand for motorization and miniaturization of optical measuring equipment,limited by system space,the rotating shaft locking mechanism of the original large theodolite is complicated,it occupies a large space and is difficult to process,it is not suitable for locking the rotating shaft of small theodolite.According to the characteristics of the project,small theodolite shaft locking struc-ture is designed in this paper,it has the characteristics of high stability,simple structure,small processing difficulty and small space occupa-tion,etc.It can realize?the rotating shaft locking of theodolite at any angle,realize gaze function.The composition and working principle of the locking mechanism are introduced and expounded in detail,after calculation select the material of the core components,The practi-cal results show that the structure is reasonable.
