Research on fixture design of gantry double station multi-axis machining center
This paper analyzes the working conditions of the group jig of double station multi-axis machining center of gantry woodworking.Because the synchronous belt transmission has the advantages of compact structure,few parts,high transmission effi-ciency and low cost,the design method of the multi-slave synchronous belt transmission of the group jig is determined.The formula for calculating the angle and length of the multi-driven wheel is derived by using the transmission diagram.The formula is used to cal-culate the angle of the wheel and the length of the synchronous belt,and the type of the synchronous belt.Finally,based on the calcu-lation results,the specific structure of the group of fixtures is designed.The finite element analysis is carried out on the rotating shaft of the power end center component,and the displacement cloud diagram of the stress and strain gauge is obtained.The maximum de-formation is 0.0107 mm and the maximum stress is 3.548e+7 N/m2,and the rotating shaft design meets the design requirements.The purpose of this paper is to provide technical reference for the actual production and application of double station multi-axis machin-ing center for gantry woodworking.
