普通车床尾架结构分为尾架体和底板两层。尾架体与底板的上平面接触,并和平面上一条带斜面的筋接触定位,且只能做横向调整。由于频繁使用磨损,造成尾架套筒中心线低于床头主轴中心线,一般相差0.2～0.5mm,有的相差还要更多,这是车床使用中普遍存在的问题。为使其等高,必须在尾架 Ordinary lathe tailstock structure is divided into the tailstock body and floor two. The tailstock body is in contact with the upper plane of the soleplate and is in contact with a beveled rib in the plane and can only be adjusted transversely. Due to the frequent use of wear and tear, causing the tailstock sleeve centerline lower than the centerline of the bed head spindle, the general difference of 0.2 ~ 0.5mm, some even more difference, which is commonly used in the lathe problems. To make it contour, it must be on the tailstock
