| As a precision position sensor, encoder is applied in every field widely, including military and civilian. With the requirement of the improvement of encoder accuracy and productivity, improving the accuracy of the encoder has became a various issue. Conventional encoder code disk and slit are assembled by the relevant mechanical realization, it has both deviation of the machining tolerances and assembly error. To solve the above problems, we design a encoder shafting geometric tolerance adjusting platform,which is reducing the technical requirements of parts machining and assembly sectors, with high accuracy, versatility and strong efficiency etc.Firstly, discusses the background and significance of the paper and show the main structure and content of the paper. Secondly, analyze the principle of the encoder and study the encoder shaft shape and position errors, summarize the factors which affect the accuracy of encoders. Thirdly, design encoder shafting form and position tolerance adjusting platform, including the modal analysis of the quick clamping mechanism of the encoder shafting form and position tolerance adjusting platform. Then design the servo feed control system and optical line detection system of the platform, including hardware design and software design. Finally, use the mathematical modeling and simulation to analyse the system, and processing the data. |
