Structural Design And Analysis Of The Anti-Jamming Transfer Device And The Docking Measurement Test Stand For Automatic Assembly Of Cabin Segments

Since the 21 st century,the development and transformation of industrial manufacturing technology is promoted by the introduction of Industry 4.0.The technology of aerospace and aviation manufacturing represents the level and strength of the highest manufacturing technology in a country,and the development trend of aerospace and aviation manufacturing is advanced manufacturing and intelligent assembly.Although China’s missile technology ranks in the forefront of the world,compared with Western developed countries,China’s missile production methods are still relatively backward and mainly based on manual operations,the degree of assembly automation is low.In order to improve the assembly efficiency of missiles and improve the accuracy and consistency of missile assembly,this paper draws on the cutting-edge technologies in related fields both at home and abroad to study the key technologies of the automatic assembly system of the cabin and explore the advanced technology of missile automatic assembly,and presents measures to improve the transfer of cabin,and verify the feasibility of non-contact measurement technology to guide the missile assembly.The main work of this paper can be summarized as follows:The research status of industrial transfer devices is discussed and the shortages in missile transfer in China are summarized,and solutions are proposed.The overall demand of the automatic docking assembly system is analyzed.The overall structural scheme design of the assembly system is expounded.The functional objectives of each subsystem are analyzed and the structural scheme design of each subsystem is proposed.On the basis of clarifying the target functions to be achieved by the transfer device,a structural design plan for the transfer device is proposed,and the specific structural design of the transfer device and the selection of key components are completed.The mechanical simulation of the transfer device is completed by using the finite element simulation software,and according to the results of simulation analysis results,the accuracy analysis and strength verification of the transfer device are completed.The special experimental bench for position measurement of cabin segment is designed.According to the functional requirements of posture measuring special test bench,the concrete structural design of the test bench is completed,and the test bench machining and installation are completed.And,the function test and precision analysis of the processed test bench are carried out.At present,the cabin posture measurement experiment has been completed on the experimental platform,and the measurement accuracy specifications have been achieved.
