INE FOR PROCESSING PARTS WITH A SEVEN-LINK SPATIAL MECHANISM - SYNTHESIS AND RESEARCH

Abstract

Synthesis of a seven-link spatial statically determined mechanism without redundant (passive) connection with an additional moving link of a machine for processing parts, followed by an analytical study
of its main structural and geometric parameters. Methodology.  An  analytical  research  method  was  used  based  on  the  geometric  and  structural synthesis  of  a  spatial  seven-link  statically  defined  mechanism  with  an  additional  movable  link  without
redundant communication of the machine for processing parts; 3D modeling of the machine was performed in the SolidWorks 2016 computer-aided design system. Results.  On  the  basis  of  structural  synthesis,  the  design  of  a  seven-link  spatial  statically  defined mechanism  with  an  additional  movable link  of  the machine for processing  parts is  proposed,  there is  no redundant  connection  in  the  kinematic  chain  of  the  spatial  mechanism,  3D  modeling  of  the  machine  is performed  in  the  CAD  system  SolidWorks  2016.  Analytical  studies  of  the  main  geometric  and  design parameters of the developed machine are carried out. Scientific novelty. The relationship between various geometric parameters of the spatial seven-link statically determined mechanism is established, which makes it possible to calculate the optimal ratio of the
lengths of the links of the mechanism to ensure the smooth functioning of the machine without jamming its spatial mechanism.  Practical significance. A new design of a machine for processing parts has been developed, based on  a  seven-section  spatial  statically  determined  mechanism  with  an  additional  moving  link  without redundant  communication.  Mathematical  dependences  are  obtained  for  calculating  its  basic  design  and geometric parameters. These dependencies can be used by the corresponding machine-building enterprises at the design stage of this type of equipment.
