这里介绍一种万向支架,它能在工件上切割不同的角度工件由压板压在旋臂上,松开螺钉1,旋臂可旋转180°以上,当然还可以把整个支架翻180°。松开螺钉2,转轴可达360°,这样,就可以将工件作任意角度的旋转了。旋轴的精度,将取决于支架加工和刻度的精度,一般可达±10′以下。 Here is a universal bracket that cuts different angles on the workpiece. The workpiece is pressed against the arm by the pressure plate, the screw 1 is released, the arm is rotated by 180 °, and of course, the entire bracket can be turned 180 °. Loosen the screw 2, the shaft up to 360 °, so that the workpiece can be rotated at any angle. The accuracy of the rotary axis will depend on the accuracy of the carriage machining and graduation, generally up to ± 10 ’.
