在机械加工中,要加工出分度精度高和对称性好的齿(槽)形是很困难的。为此,我们设计了如图1所示精密分度台,经使用效果很好。该夹具用于磨加工矩形花键环规时,加工后的花键环规能达到量规设计要求。以外圆为100mm的10键矩形花键环规为例,其分度误差为0.008mm,相邻误差为0.004mm,光洁度可达(?)9左右。夹具安装在花键磨床上加工。用于加工对称性端面齿(槽)时,对称度为0.005mm。使用夹具时,将工件安装在工作台上,使工件中心与工作台回转中心重合。用手拉动柔性带17,牵动卡
In machining, it is very difficult to process the tooth (groove) shape with high indexing accuracy and good symmetry. To this end, we designed a precision indexing table shown in Figure 1, the use of good results. The fixture is used to grind the rectangular spline ring gauge, the processed spline ring gauge can meet the gauge design requirements. For example, the 10-point rectangular spline ring with the outer circle of 100mm has an indexing error of 0.008mm, an adjacent error of 0.004mm and a smoothness of about 9. Fixture installed in the spline grinder processing. Symmetry is 0.005mm when machining symmetrical face teeth. When using the jig, the workpiece is mounted on the workbench so that the work center coincides with the rotation center of the workbench. Hand with a flexible belt 17, affecting card
