The Modular Design System Of Automatic Driling And Simulation Analysis

Robot drilling system is favored by aviation enterprises for its high automation,high precision and high efficiency.The modular design of the hole system has begun to appear in the design of various colleges and universities.However,the standard is not uniform and the diversity of the methods still restricts the development of the domestic system.Therefore,the terminal executor is divided into several modules,and the model is built to simulate the porosity of the system.First,the end execution is divided into four modules according to function: detection module,compaction module,drilling module and chip sucking module.The components of each module are designed to design reasonable module size parameters for specific machining requirements.According to the material,force and processing conditions of the wing and fuselage panel,choose the appropriate bit type and simulate the performance of the hole.Establish A 3D model of twist drill and a simplified model for machining work piece,and select main material of aircraft is processed and the aluminum alloy material.The relationship between axial force and cutting speed,feed rate and pore size is analyzed,and the force curve is drawn to show the curve changes between them.The establishment of the drilling force kinematics model,simulation by Simulink finite element simulation accuracy.Finally,the drilling force model of the radial runout of the bit is set up.Through the WinPP software,the precision of the end actuator is analyzed by the Runge-Kutta method.The change of the precision of the hole making system with different stiffness is different.
