一、概论 用於磨制样板的复杂曲面的万能夹具机构,应满足如下的要求: 1.当加工曲面的弧度时,使工件可以绕其中心旋转,并在360°范围内能保证正确地固定角度。 2.为了将被磨的圆弧中心与夹具旋转部分的中心相重合,在直角座标系统内给与工件正确移动的可能性。 3.能够卡固工件来 I. INTRODUCTION The universal fixture mechanism used to grind complex curved surfaces should meet the following requirements: 1. When the curvature of the curved surface is machined, the workpiece can be rotated around its center and can be correctly fixed within 360 ° angle. 2. To align the center of the arc to be ground with the center of the rotating part of the fixture, give the possibility of a correct movement of the workpiece within the Cartesian coordinate system. 3. To be able to clamp the workpiece
