摘要
铣床是普通精度级万能铣床,它运用加工各种轴类,套筒类和盘类零件上的回转表面,以及铣削端面等,是应用最广泛的铣床。
铣床操作箱体是机床的基础构件,机床的各个主要部件和零件都装在操作箱体或操作箱体的导轨上作相对运动。在切削中,刀具与工件的相互作用力传递到操作箱体上而使操作箱体变形
操作箱体的变形和振动直影响到被加工零件的精度和表面粗糙度,因此,操作箱体是铣床上极为重要的一个部件。
而导轨,则是操作箱体上极为重要的一个部分,操作箱体上共有四条导轨,其中,有两条导轨是拖板用的导轨,另外两条导轨为尾座导轨,其作用为导向和承载,所以,以导轨要求有较高的的导向精度,结构简单,工艺好等特点。
本次的设计主要就是针对加工操作箱体导轨而进行设计的,为了保证导轨的精度,降低工人的劳动强度,操作箱体导轨的加工基准选用导轨本身即“自为基准”原则。本次设计的主要内容是设计一个调节装置,其作用就是在加工操作箱体时对操作箱体在空间的各个位置进行调节,限于目前的水平有限,希望各位老师给予指正。
