Abstract

本实用新型公开了一种直径可调的回转体定心夹紧装置,包括呈空心圆柱体的盘体和工件定心机构,盘体由机器驱动,所述盘体包括上半环和下半环,上半环和下半环的连接处设置有回转轴,上半环可绕回转轴向后翻转;与回转轴对应的定位销上设置有能使上半环和下半环固定不动的夹紧螺栓和夹紧螺母;所述工件定心机构为沿盘体周向设置的可使工件中心和机器回转中心重合的调心螺钉,调心螺钉上设置有防止其位置变动的紧定螺钉;所述下半环通过过渡盘与机器的输出轴固定。本实用新型结构简单、使用方便,能有效提高加工效率。
The utility model discloses a revolution body centering clamping device with an adjustable diameter. The revolution body centering clamping device comprises a hollow cylindrical plate body and workpiece centering mechanisms. The plate body is driven by a machine and comprises an upper half ring and a lower half ring. The joint of the upper half ring and the lower half ring is provided with a revolution shaft, and the upper half ring can be overturned backwards around the revolution shaft. A locating pin corresponding to the revolution shaft is provided with a clamping bolt and a clamping nut enabling the upper half ring and the lower half ring to be fixed. The workpiece centering mechanisms are centering nuts which are arranged in the peripheral direction of the plate body and enable the center of a workpiece to coincide with the revolution center of the machine. The centering nuts are provided with set screws preventing the positions of the centering nuts from changing. The lower half ring is fixed to an output shaft of the machine through a transition plate. The revolution body centering clamp body is simple in structure, convenient to use and capable of effectively improving machining efficiency.
