通常在修理卧式铣床时,要保证悬梁挂架孔与主轴的同心度,都采用专用的夹具进行镗孔修复。我厂在修复X60卧铣挂架时,机修工人想出了一个比较简易的办法。采用这种办法,只需调整好悬梁导轨与床身导轨槽成滑动配合,将刮研好的挂架紧固在悬梁上,镗刀装在主轴锥孔中,再在工作台上紧固一个弯板(位于悬梁前方),然后就可开车镗孔。镗孔时,工作台自动走刀,弯板就推动悬梁向前移动,达到了纵向进给。挂架孔径尺寸的大小,可以根据要求,调节装在镗刀杆内的
Usually in the repair of horizontal milling machine, to ensure that the hanging beam hole and the spindle concentricity, are using a dedicated fixture for boring repair. I plant repair X60 horizontal milling rack, the mechanic come up with a more simple way. In this way, just adjust the cantilever rail and the bed rail slide into a sliding fit, the scraping rack is fastened to the suspended beam, boring cutter installed in the spindle taper hole, and then fasten a Bend the plate (in front of the cantilever beam) and then bore the car. Boring, the table automatically walk the knife, curved plate to promote the cantilever move forward to reach the longitudinal feed. Pylon aperture size size, according to requirements, adjust the installed in the boring bar
