Design Of Polycrystalline Diamond Manipulator And Stress Analysis Of Cubic Press Anvil

With the development of modern industry，the application of the manipulator hasbeen more and more widely used.Because of the progress of the times and thedevelopment of the technology，the manipulator has played a huge and irreplaceablerole.So manipulator are significant to life safety and modernization of production.This paper not only adopts universal robot program to design, but also needs toconsider the actual situation of accessing polycrystalline diamond and various aspectsof the work environment and the actual position.Firstly，according to design theory，the preliminary robot morphology was designed.The second step is to analyze andselect the drive according to the actual situation.The third step is to select the variousparts in accordance with the actual path of the robot and the working stroke motionparameters. The fourth, according to the position of the various parts of a robotdesigned for each connection, the various parts of the selected was linked up, anddraw out the assembly drawing. The fifth, part of each design will be drawn into adrawing to facilitate manufacturing.In addition，stress analysis and structure optimization on cemented carbide anvilsof cubic apparatus is one of the important means for improving design life.Firstly,themaximum stress and it’s location of cemented carbide anvils are computed by usingthe finite element analysis method and elastic mechanics knowledge，then the reasonwhy the maximum stress appears at the junction of the cone and the top surface isanalyzed.Secondly,it is concluded that double chamfer is better than the currentcemented carbide anvils by putting forward a double chamfered cemented carbideanvil and its simulation,.Finally, the analysis of maximum stress in different kinds ofstructure parameters,which gives a guidance for further optimization.
