技术介绍
数控车轮车床是一种功能完善的数控用车轮车床,主要用于轨距为1435mm的铁路货车RE2、RE2A、RE2B、RD2、RDF型的轮缘、踏面及内侧面的加工和修理。机床采用卧式布局形式,通过左右床头箱套筒顶尖定心方式,再通过卡盘上的弧形卡爪卡紧轮对并带动轮对旋转。左右数控刀架设有自动对刀装置,可实现刀具自动定位、自动完成轮缘踏面的修理加工。机床设有抬升装置,可自动将轮对送到机床中心位置上。当铁路货车车辆的路轮对在铁轨上运行一段时间后,轮对轮廓达到旋修条件后,必须在铁路车辆段或站修所进行旋修加工。传统的旋修方法是将轮对从转向架解体后,把轮对左右的轴端螺钉和端盖拆卸后,运到传统数控车轮车床上加工。传统数控车轮车床采用左右顶尖顶紧方式来进行旋修加工。此顶紧方式,人工需要将轮对左右两端的前盖12、螺栓13、放松片14、施封锁15、标志板16拆卸,参看如图1和图2所示,增加了工人的劳动强度,降低工作效率。平且在加工过程中防止污染轴承还必须在轴承上加防护套,因此,传统传统 ...
