数控落地铣镗床TK6913B双驱机构位置的改进

Improvement for the Dual-drive Body Position of the CNC Floor-type Milling and Boring Machine TK6913B

通过ANSYS有限元软件分析发现,数控落地铣镗床TK6913B由于双驱机构的位置,严重阻碍了主轴箱的下移距离,而导致立柱的变形。根据这一缺陷,采取了改变双驱机构位置的办法,使立柱变形量减到最小,可提高刀具对工件的加工精度,对TK6913B的改进设计提供了理论依据。

The ANSYS FEA software results show that the column of CNC floor - type milling and boring machine TK6913B is deformed. Owing to the dual - drive body position, it severely impacts on the downward movement of the spindle box distance. According to this defect, it takes a way to change ly,the column＇s improves the tool of the workpiece. dualdrive body position. Final- deformation is decreased. And it against the machining accuracy of the workpiece.
