已知的工件定位法,在坯件一个定位器情况下,由于完成几个任意分布的表面的机械加工、装配或检查,工艺可能性受到限制,当从一个面转到下一个面时,工件或刀具每次都要进行几个位移。古比雪夫工学院研制成一种工件定位新方法(发明证书号1238935),可以扩大工艺性,至少能保证四个具有交叉轴的被加工面的工件定位。为了使工件在一个定位器上完成一定的动作,可以使工件的回转点和与所有的被加工面相切的球的中心相重合。具有被加工面1,2,5和6的工件4,其对应的几何轴Ⅰ、Ⅱ、Ⅵ、Ⅶ交叉,和夹具的定位元件3和7(夹具条件未表明),其几何轴Ⅴ和Ⅷ相交成某一角度,一起安置在机床的工作台上。在这种情况下,定位元件
Known workpiece positioning methods, where a blank is a locator, have limited process possibilities due to the machining, assembly or inspection of several randomly distributed surfaces, and when the workpiece is transferred from one side to the next, Or a few displacements of the tool each time. A new method for workpiece positioning (Invention Certificate No. 1238935) has been developed by Gubitchev Institute of Technology to extend the processability and at least ensure the positioning of four workpieces with machined surfaces with cross-axes. In order for the workpiece to perform a certain action on a positioner, it is possible to bring the point of rotation of the workpiece into coincidence with the center of the ball tangent to all the surfaces to be machined. The workpieces 4 with the workpieces 1, 2, 5 and 6 to be machined, whose corresponding geometrical axes I, II, VI, VII intersect and the positioning elements 3 and 7 of the jig (the jig conditions are not indicated), the geometrical axes V and VIII Intersect at a certain angle, together placed on the machine table. In this case, locate the component
