过去,外圆磨床在加工工件时,为了延长砂轮寿命,提高加工效率,一般采用大直径砂轮,这样带来了更换砂轮困难,机构庞大、复杂等问题;而且机床本身的调整部位多,对工人的技术水平要求较高,维修保养不便。针对这一系列问题,日本丰田公司研制了一种新型摆动式外圆磨床,这种磨床采用了小直径砂轮,结构简单,克服了以往外圆磨床的一些不足之处,适合于较大批量的工件加工,现已在大批量生产的工厂中使用,图1所示为该机床结构示意图。摆动式外圆磨床的工作原理如图2所示。磨床的砂轮、工件、砂轮修整器依照图2的位置布局,加工
In the past, cylindrical grinder in the processing of the workpiece, in order to extend the life of the wheel and improve processing efficiency, the general use of large diameter wheel, this brings the replacement wheel difficult, large and complex bodies and other issues; and the machine itself to adjust more parts of the workers The higher technical requirements, maintenance inconvenience. In response to this series of issues, Japan’s Toyota developed a new type of swing cylindrical grinder, this grinder with a small diameter wheel, simple structure, to overcome some of the shortcomings of the previous cylindrical grinding machine, suitable for larger quantities Workpiece processing, is now used in mass production factories, Figure 1 shows the schematic diagram of the machine tool. Swing-type cylindrical grinder works shown in Figure 2. Grinder grinding wheel, workpiece, wheel dresser layout in accordance with Figure 2, processing
