Strength analysis and optimization of writing mechanism of steel billet marking machine
According to steel billet marking theory of plasma arc nicking,the paper designs a dual laser ranging marking machine against online marking of special steel billet and realizes multi-character marking of the end face of hot steel billet.Writing mechanism bases on the rectangular coordinates marking form,Z axis adopts cantilever structure.It completes the overall marking task utilizing the synergy of KK module in X axis,Y axis and Z axis.It makes modal analysis on the writing mechanism model established by Pro/Enginner utilizing ANSYS Workbench at the position of X1Y1Z1,and obtains the first six order modal frequency and analyzes the vibration in the writing process.Moreover,the paper analyzes the static structure of the cantilever of writing mechanism,computes its maximum stress and total deformation.To make the writing mechanism reach the target of light weight,the paper optimizes Z-axis cantilever of writing mechanism.According to the analysis,it is known that the optimized Z-axis cantilever of the writing mechanism still meets the strength and rigidity requirement and total mass declines approximately 30%.
