Research On Micro Feed Grinding System Of The Inner Hole Non-circular Grinder

Micro feed grinding system is a major part of the inner hole non-circular grinder,the rationality of the design not only determines the positioning precision of thegrinding system and machining precision, but also to the performance of the wholemachine tools have great influence. As a kind of high precision and complexmechanical and electrical products, in order to obtain accurate feeding and machiningprecision, good must be conducted to the design of micro feed grinding system strictly,in this paper, the design structure of the modal analysis, static structure analysis,kinematic simulation research.Within this article the inner hole non-circular grinder micro feed grinding systemas the research object, to predict the feasibility, main research contents include:First of all, the establishment of micro feed grinding system mathematical modelof non-circular forming theory, to lay a solid foundation for further study, using C++software program, testing of non-circular forming theory is correct.Secondly, using the Solidworks drawing parts and assembly of micro feedgrinding system diagram, prepare for the subsequent simulation analysis.Again, the ANSYS finite element simulation software of micro feeding systemaffect the machining accuracy of grinding and worm drive system of main componentsof the modal analysis and static structure analysis, the multi-body dynamics analysis,get the inherent frequency and vibration mode of parts of figure, internal relatedparameters such as stress, strain, based on the various components and worm drivesystem design optimization.Finally, the application of ADAMS software to micro feed grinding systemkinematics simulation, based on spindle rotation acceleration and velocity curve and sliding saddle feed acceleration and velocity curve were analyzed, and the predictedmicro feed grinding system design scheme is feasible.
