Research on automobile open checking fixture based on SLA process
In order to solve the problems of large quantity of tools and checking fixtures,high ma-chining cost and long production cycle in the process of automobile manufacturing,SLA process was used to study the manufacture of automobile open checking fixture.The open checking fix-ture of the rear triangle window was printed by FDM process and SLA process respectively,the size measurement and accuracy analysis of the open checking fixture were carried out,and the size accuracy was less than 0.2 mm.Based on the usage environment of automobile open checking fixture,the performance parameters of a variety of liquid photosensitive resin were compared,a va-riety of equipment and materials were compared and analyzed from the perspective of cost,consid-ering the factors such as deformation,discoloration and cost,it was an economical and feasible technical measure to print automobile checking fixture with SLA process.
