滚子式拨盘多应用于磨削加工,它可以代替手动鸡心夹头,具有结构简单,操作方便,能提高零件加工精度和劳动生产率,适于大量生产使用。一、滚子式拨盘的工作原理滚子式拨盘结构如图1所示。工件装到两顶尖上,由于主轴的旋转,滚子式拨盘即能自动夹紧工件进行磨削加工。当主轴转动时通过螺栓12,带动本体1转动,通过拨销8带动偏心套14转动,由于偏心的原理,利用偏心 Roller dial used in grinding, it can replace the manual chick chuck, with simple structure, easy operation, can improve the machining accuracy and labor productivity, suitable for mass production. First, the working principle of roller dial Roller dial structure shown in Figure 1. The workpiece is mounted on the two tops. Due to the rotation of the spindle, the roller dial automatically grips the workpiece for grinding. When the spindle rotates, the main body 1 is driven to rotate by the bolt 12, and the eccentric sleeve 14 is driven to rotate by the dial pin 8. Due to the principle of eccentricity, the eccentricity
