X62W铣床横向螺母托架(图1)是铣床的一个主要零件,铣床工作台是靠横向丝杠的旋转,通过固定在工作台下面的螺母托架,带动它沿着升降台(图2)上的矩形导轨Ⅰ、Ⅱ往复运动。因此,要求导轨Ⅰ、Ⅱ平行于孔D;孔D与孔A在同一轴线上,工作台运动才能轻快平稳。大修铣床时,升降台和下拖板结合的导轨面,经过不同程度的修整或刮研后,下拖板相对下沉、偏移,使横向丝杠螺母座的孔A与横向丝杠轴颈定 X62W milling machine horizontal nut bracket (Figure 1) is a major part of the milling machine, milling machine table by rotating the horizontal screw, driven by the nut bracket fixed to the table below, along the lift (Figure 2) Rectangular rails Ⅰ, Ⅱ reciprocating motion. Therefore, it is required that the guide rails I and II be parallel to the hole D. The hole D and the hole A are on the same axis, and the worktable can move lightly and smoothly. Overhaul milling machine, the lifting platform and the lower rail combined rail surface, after varying degrees of trimming or scraping, the lower siding relative sinking, offset, so that the horizontal screw nut seat hole A and the horizontal screw shaft neck set
