Deviation Analysis and Optimization of C-shaped Latch Mechanism Based on Modified Jacobian Screw Model
By the tolerance analysis method based on the modified Jacobian screw model,analyzes the installation position and motion accuracy of the C-shaped latch in the C-shaped latch mechanism of the guide lock,compares their results with the ones by 3DCS software to verify the applicability of the method.The kinematics theory of the robot is applied to extend the static tolerance analysis to the dynamic tolerance analysis,the position accuracy of the C-shaped latch in the process of motion is analyzed,and the Taguchi based tolerance contribution degree and sensitivity are used to optimize the analysis and tolerance design,obtaining the factors with greater influence.
