The sliding table is a general component of combine machine tool, which can realize the feed movement of machine tool. The combine machine tool which based on sliding table, allocate all kinds of slice, can finish drill, expansion and so on.The project must finish the design of sliding table and drive system. The drive system of sliding table is consist of power slipway and two electric machine drive device. Drive device is the kind of two electric machine differential mechanism drive. Sliding table could finish the motive cycle feed: fast feed, work feed, stay and fast recession.The design dates which given in the duty paper:The broad of the sliding table: B = 400mm The route : S = 400mmThe speed of work feed: V =15.4 ~ 600mm/minThe speed of fast feed: V = 6.3m/minFeeding force : F = 20000NAfter looking- up some material, analyzing given conditions, the scheme could de decided. At first, we can decide feeding force as the warranty of choose power sliding table; Decide the slice as the warranty of decide the dimension of spindle, power drive shaft and gear ; decide capacity as to choose electric machine. After finish the choose and calculation of the electric machine , it must performance the choose and calculation of movement parameter of the sliding table drive device , design and calculation of the drive parts , design and check of the sliding table and so on.Through this design of mechanical drive power sliding table, I have a pointed knowledge of the machine tool and its general component , strengthen the theory knowledge which have learned . at the same time , improve myself professional technology .Key word : Mechanical power sliding table Differential mechanismDrive system Power drive shaftTeacher:
