如何给出纵切自动车床凸轮各段曲线的制造公差,如何利用机床上的双曲轮操纵机构,正确合理地将凸轮曲线分别设计在两个凸轮上,现根据多年生产实践得出的计算公式,介绍如下: 纵切自动车床凸轮制造误差包括:曲线误差、半径误差、角度误差、凸轮曲线轮廓中心与凸轮安装孔的偏心、安装孔中心线与凸轮端面不垂直等。其中凸轮半径误差对零件加工精度影响较大。
How to give the manufacturing tolerances of the curves of each segment of the automatic lathe of longitudinal lathe, how to make use of the hyperbolic wheel operating mechanism on the machine tool to correctly and correctly design the cam curves respectively on two cams, and according to the calculation formula obtained through years of production practice , Introduced as follows: Slitting automatic lathe cam manufacturing errors include: curve error, radius error, angle error, cam curve contour center and cam mounting hole eccentricity, mounting hole centerline and cam end face is not vertical and so on. Among them, the error of cam radius has a great influence on the machining accuracy of parts.
