木屋圆木梁加工中心转塔式主轴结构设计与研究

Design and Research of Log Cabin Beam Machining Center Turret Type Spindle Structure

通过对圆木梁加工形式的分析,确定加工中心转塔式主轴结构的总体布局方案,利用SolidWorks软件对木屋圆木梁加工中心进行三维建模。完成了矩形转塔、车外圆和铣横向榫槽主轴总成、钻孔主轴总成、铣纵向榫槽主轴总成、铣端部榫槽主轴总成、转动总成的结构设计及单位切削力、切削功率等主参数的设计计算。该设计使加工中心能够一次性进行车削、铣削、钻孔等形式的加工,大大提高了木屋圆木梁的加工精度和加工效率。

Through analysis of the log beam processing form,the general layout scheme of machining center turret type spindle structure is determined and the three-dimensional（3D） modeling of log cabin beam machining center is built with Solid Works software.The structural design of rectangular turret,truning and transverse groove milling spindle assembly,boring spindle assembly,vertical milling groove spindle assembly.end milling groove,and rotary assembly are completed.Design and calculation of main parameters,such as cutting force and cutting power are also completed.The designed machining center can be a one-lime turning,milling,drilling and oilier forms of processing machine which greatly improves the machining accuracy and machining efficiency of log cabin beam.
