ABSTRACT
 
In this paper, for the docking program of some large-scale equipment power plant and the gear reduction device’ research, it aims to design a docking platform with real-time feedback function, which can achieve the improvement of docking precision and success rate and reduce the adjustment time while realizing the docking of assembly parts. At the same time, the platform in the realization of docking function, there is a certain degree of adaptability. It can adjust their position, to deal with different conditions of the docking requirements.
 
The paper begins with the functional requirements of the platform, analysis platform mechanism freedom, complete action decomposition and institutional selection, and determine the overall design of the platform to make it meet the functional requirements from the principle.
 
Second, for the key parts such as gears, drive screw, drive shaft and rail, doing the relevant design calculation and completing the strength, stiffness and other performance analysis and verification to ensure that the design of the structure can successfully complete the design task.
 
At the same time, integrated specific structure size of platform, complete the detailed structure of the platform design, determine cooperate precision of the key parts, complete the assembly diagram and parts diagram, and use 3D software to establish the three-dimensional model of the partial structure.
 
Finally, from the point of view of the accuracy of regulation, the control scheme of the adjustment platform and some control elements should be selected and arranged, and the adjustment precision should be analyzed.
 
Keywords: docking platform, structural design, screw, rail, precision
