Multifunctional clamp based on three-jaw self-centering chuck clamping

The invention provides a multifunctional clamp based on three-jaw self-centering chuck clamping. The middle part of the multifunctional clamp is specifically a positioning part of a clamping terminal surface of a three-jaw chuck, and two ends of the multifunctional clamp are respectively a first clamping end and a second clamping end; a first clamping cavity is formed in the first clamping end, and the first clamping cavity is used for clamping a first workpiece; a second clamping cavity is formed in the second clamping end, and the second clamping cavity is used for clamping a second workpiece; the internal shapes of the first clamping cavity and the second clamping cavity are different; and by means of the technical scheme, the effect of clamping two kinds of workpieces at the same time can be achieved. 本发明提供了一种基于三爪自定心卡盘夹持的多功能夹具，所述多功能夹具的中部具体为三爪卡盘夹持终端面的定位部，所述多功能夹具的两端分别为第一夹持端及第二夹持端；所述第一夹持端内设置有第一夹持腔体，所述第一夹持腔体用于夹持第一工件；所述第二夹持端内设置有第二夹持腔体，所述第二夹持腔体用于夹持第二工件；所述第一夹持腔体及第二夹持腔体的内部形状不一；应用本技术方案可实现同时装夹两种工件的效果。
