Four Branches Of Five-axis Mechanism And Analysis Of Serial And Parallel Machine Tool

In surface processing wheel because the surface of complex shapes,traditional arts often unable to facilitate processing.Human processing,large equipment is time-consuming.In view of such a complex surface machining has a new configuration of four branches of five-axis machine tool,machine tool structure synthesis of parallel and series advantage,make up the existing hybrid machine tool configurations of vacancies,and preliminary analyses of kinematic and mechanical characteristics.Firstly,according to the ship motion parameters,the design index of the simulation platform is developed.For existing parallel mechanisms are difficult to achieve large and heavy loading,a 3-DOF redundant actuation parallel mechanism with joint static load balancing device is presented,and analyzed its inverse position.Based on which,the reachable workspace is searched by the constraint condition of the mechanism.Processing first workpiece characteristics,based on the success of existing institutions,by general principles of selection,type a cross arrangement of r(2-UPR/2-UPS)five-axis parallel machine tool of the new configuration,using geometric methods to analyze the singular obtained preliminary arrangement of the hinges.Following preliminary descriptions of machine configuration and structure design,and parallel and hybrid institutions institutions are divided into two parts,respectively the institutional models,analyze their own characteristics,calculation of motion of a map,gives analysis of a class of hybrid kinematic method and Matlab modeling and Solidworks kinematics simulation results.And work space for the machine to do a preliminary analysis.Analysis of the institutions of the joint range of motion,using three dimensional Cartesian searching approach represented by Matlab workspace using three dimensional images.Multiple variables are given work and the relationship between volume and space,and work with the machine work of the institutions of the different characteristics of spatial relations and expressed through images.Finally,R(2-UPR/2-UPS)of first-order coefficients to analyze the characteristics of the institution,represents the index as a result in the image to optimize the design.This article from the body of static,rigidity,flexibility for agencies to conduct a comprehensive analysis and dynamic simulation on mechanism.
