| Heavy duty CNC vertical lathe is for machining large diameter and heavy. Itoccupies an important position in the CNC machine tool market. It is in the defenseindustry application and is a sign of that Chinese become a manufacturing powerand power. Cross beam as supporting components is very important in the heavy CNCvertical lathe. It has complex structure. Its load bearing is more than the small beam inthe lathe. It is related to the geometric accuracy and the crossbeam guide rail thewhole machine assembly of the static, dynamic stiffness characteristics. To optimizethe design research on the lathe is very imporment.In this paper, Wuhan heavy machine tool group production of10m heavy CNCdouble column vertical lathe beams rod design and finite element analysis are done.Numerical control drive systems in beam in CNC heavy duty vertical lathe arestudied in this paper to Wuhan Heavy Duty Machine Tool Group production of CNCheavy duty vertical lathe. It analyses the types, servo motor and ball screwpretightening mode, design and selection, the selection of design according tothe flow chart of ten steps to go. In-depth analysis of screw bearing, servo motor isdone. At the same time the beam hydraulic control parts in CNC heavy duty verticallathe are studied, in order to study the hydrostatic pressure guide rail and beam ofhydraulic clamping mechanism. The selection of design parameters for the hydraulicsystem and long pumps of the constant flow hydrostatic guideway are done.The clamping mechanism of disc spring combination type selection is researchedand in depth analysis of machine tool clamping, relax on Spring three stateparameters are done. The processing design results through heavy CNC verticallathe machine tool that is very successful. |
