Coarse Fine Milling Type Ⅴ Engine Box Body45Degrees Face Special Machine Design And Research

The application of modular machine tool machining batch parts is high production efficiency and low machine cost,which is the direction of development of mechanical processing.The mission of the design is " Coarse fine milling type V engine box body45degrees face special machine design and research," The thesis mainly about the special machine tool of the overall layout design, machine tool clamp design and milling machine pillar finite element analysis and optimization.The desigh of modular machine tool need meet achieving coarsing and fining Deutz engine box45°surface, automatic positioning, clamping, relaxing,at the same time, fixture parts to be processed according to the size and make the appropriate adjustments to meet the machining of precision parts machining and production efficiency.In the design process, firstly analyzed the technical requirements of the parts, determined the combination of spare parts in the milling machine processing technology solutions. In the process, determine the positioning of the workpiece, process margin between the tool materials and structure and configuration of machine types and so on. Then the overall layout of the combined milling machine design. Here the mainly draw based on the machining requirements of the "three-figure one-card": the process map parts to be processed, processing diagram, the combination of milling efficiency card combination milling machine linked dimensions, but also for the machine tool and part of the selection the design of specific components. Then according to part of the structural features, processing positioning, milling force size designed a special fixture combination milling machine.Through these work started, initially completed combination the general structure of the milling machine design and machine tool fixture design. Then through3d software based on the vertical milling machine3d model, using the finite element software based on the finite element calculation model, and a column the static strength just strength analysis, the calculation of the stress and deformation of the pillar. Through the modal analysis method, the pillar1to8order natural frequency and vibration mode. The analysis results show that the current column the design model stiffness, strength is better. Optimize the pillar of milling machine, the optimized pillar structure, guaranteed to meet the machining accuracy and in production, under the premise of quality, reduce the inherent frequency also get the corresponding improvement.
