磨推力球轴承套圈外圆,一般是将套圈串在一个芯轴上用螺母锁紧,并预先架在平台V形铁上用百分表校正其外圆同心度,使之留磨余量均匀,然后在普通外圆磨床上磨削.这样工步麻烦,效率低,而且由于疏忽,往往出现由于装夹偏心某些套圈一边磨不到,造成废品.过去我厂在无心磨床上磨推力球轴承套圈时有困难,这主要由于套圈是薄片,重心不稳,当通过磨削区时容易摇晃或倒下.后来厂技革三结合小组设计出一种简单的浮动夹具(图1),经过一年来的生产实践证明,效果很好,有如下优点:(一)装卸工 Grinding thrust ball bearing ferrule outer ring, the ferrule ring is generally locked with a nut on the mandrel, and pre-racked on the platform V-shaped iron with a dial gauge to calibrate its cylindrical concentricity, so that the remaining grinding The amount of uniform, and then grinding on a common cylindrical grinder. This step trouble, low efficiency, but also due to negligence, often due to clamping eccentricity while not wearing some of the rings, resulting in waste. In the past my factory in the centerless grinder Thrust ball bearing ferrule grinding difficulties, mainly due to the ferrule is thin, unstable center of gravity, when passing through the grinding zone easy to shake or fall. Later, the plant technology leather combination of three groups to design a simple floating fixture Figure 1), after a year of production practice has proved that the effect is very good, has the following advantages: (a) loading and unloading
