我厂在加工某零件时,遇到了内球面Sφ90_(+0.04)~(+0.09)(见附图中的点划线部分)的加工问题,为此本人设计了这套简易的工装。 1.原理及结构 在车削过程中,车刀围绕球心作圆弧运动,配合主轴旋转,即可在工件上车出内球面,对于公差要求严格的球面,车刀尖的回转半径也得严格控制。 内球面车削装置结构如附图所示。 车削时,夹持体16装在刀架上,将销轴4的中心
I plant in the processing of a certain part, met the inner sphere S φ90 _ (+0.04) ~ (+0.09) (see the dotted line in the figure) processing problems, for which I designed this simple tooling. 1. Principle and structure In the turning process, the turning tool makes a circular arc around the center of the ball. With the rotation of the main shaft, the inner spherical surface can be driven out of the workpiece. For the spherical with strict tolerances, the turning radius of the turning tip is also strictly control. Internal spherical turning device structure as shown in the figure. Turning, the holder 16 mounted on the turret, the pin 4 will be the center
