在普通车床上加工轴承沟道(特别是轴承外圈沟道)时,由于机床本身的间隙等因素的影响,沟道位置和直径尺寸不易掌握,质量上常常出现问题。为提高轴承挖沟质量,可在车床上,设置一个挖沟简易自动测量装置,如附图所示。挖沟时先把该型号的车加工沟道标准件安装在卡具内卡紧,再摇动手柄使刀头进入沟道,与标准件沟道吻合,分别记住百分表3和16的示
When machining a bearing channel (especially a bearing outer ring channel) in an ordinary lathe, the position and the diameter of the channel are not easy to grasp because of the gap of the machine tool itself and the quality is often a problem. In order to improve the quality of bearing digging ditch, a trenching simple automatic measuring device can be set on the lathe, as shown in the attached drawing. Trench ditch when the first model of the car processing channel standard parts installed in the fixture chuck, and then shake the handle to the head into the channel, and the standard part of the channel fit, respectively, remember that the indicator 3 and 16
