Design of Self-centering Clamping Module for Arrow Cone
Given the problems of low clamping accuracy and single clamping diameter in the positioning and clamping of the cone at the present stage,after analyzing the structural characteristics of the cone and its clamping and positioning re-quirements,the three-dimensional model of the cone self-centering clamping module is established,the weak link of the cone rigidity is analyzed by using the finite element method,and the relationship model between the tightening force,down-force and tightening area of the self-centering clamping module and the deformation of the window area is established.The research scheme of the laws of various influencing factors is formulated,and the positioning error caused by the radial de-formation of the circumference at the window is analyzed.Taking the maximum deformation of the window processing area not exceeding 0.03mm as the optimization objective,the optimization design is carried out.According to the final analysis results,the relevant parameters are improved,and the cone self-centering clamping module is built to meet the performance requirements.Compared with the existing products,it has realized the unified benchmark of cone cylinder clamping in the diameter range of 550～870mm,and the clamping range has been expanded.
