Title XM40 Structural design of turret machining center
Abstract
with the social development and scientific and technological progress, require the higher structure of NC rotary table, the structure is reasonable or not, reflecting the high and low level, determines the level of size and level of accuracy of the bearing capacity of rotary table. This article describes the structure of the XM40 Rotary worktable of machining center and related theoretical calculation of the design process. CNC Rotary worktable of machining center driving structure consists of a dual lead worm gear, the transmission structure of transmission clearance can be eliminated, the machine keeps the spindle during the addition of a positioning and transmission mechanism, achieved position spindle indexing requirements. The structure guarantees the transmission precision, simple structure, reliable performance, easy to adjust, applicability, cost-effective high. Through mapping, calculation of structural design parameters, rotary table by using three dimensional design software architecture modeling and finite element analysis to the table structure, the structural design of the NC rotary table is reasonable, the design is feasible.
