立式动平衡机可收缩式接盘装置的研究与应用

Research on Retractable Adapting Plate of Vertical Balancing Machine and Its Application

设计了一种可消除夹具产生的径向力对主轴损害的可收缩式接盘装置,可应用于盘类转子的立式自动动平衡机的定位夹紧,具有消除夹具产生径向力对主轴损害的功能。将传统整体接盘分为两层分离的内外轴套筒形式,中间用可收缩式轴承将接盘内外套筒固定连接起来,组成一个整体的可收缩接盘。可收缩式轴承利用开关继电器运动,将销子产生向外的径向位移差转换成固紧件半封闭式内外套筒的轴向位移,最终达到消除主轴径向力的功能作用。相比较于现阶段解决此类问题的"主轴抽轴技术"具有结构简单、易于安装及成本较低等优点,可应用于盘类转子的立式自动动平衡机的工件定位夹紧。

This paper designs a retractable adapting plate device which can be used for positioning and clamping device of the disk rotors on dynamic balancing machine to prevent the damage of the spindle with the radial force generated by the fixture. When the traditional joint plate is divided into two separated layers ---the inner and outer sleeve, the refractable bearing can be used to fix and connect the inner and outer sleeves into the whole retractable adapting plate. The movement of the retractable bearing controlled by switch relay, axial displacement of the semi-closed inner and outer sleeve is converted by outward radial displacement difference produced by the pin so as to ultimately eliminate the radial force of the spindle. This design has advantages of simple structure, easy installation and low cost. compared with usual spindle shaft technology and can be applied to position and clamp disk rotors on dynamic balancing machine.
