C8955型铲齿车床是刀具制造中用于铲齿和铲磨齿轮滚刀、齿轮铣刀等各种铲齿刀具的机床,其加工精度的高低直接影响到刀具的精度。随着齿轮新标准的贯彻实施,对齿轮刀具的精度要求也随之提高,因此对铲齿车床的精度要求也更高,这样就给机床修理增加了难度。为此,我厂机修人员认真总结了三十年来C8955型铲齿车床的修理经验,制订了一些修理要点,收到了较好效果。现介绍如下: 一、主轴丝杠系统的修理要点 1.主轴箱体 C8955型铲齿车床主轴箱是剖分式结构。为了把主轴系统变形控制在最小范围内,要求上下箱体的结
C8955-type shovel-tooth lathe is used in the manufacture of tools for shovel gear and shovel grinding gear hobs, gear milling cutter and other shovel tooth cutting tools, the level of precision directly affects the accuracy of the tool. With the implementation of the new gear standards, the precision requirements of gear cutting tools also increase, so the accuracy of the shovel lathe is also higher, thus giving the machine repair increased difficulty. To this end, I plant mechanics seriously summed up the thirty-eight years of experience in the repair of C8955-type shovel lathe, made some repairs points, received good results. Are introduced as follows: First, the main spindle screw system repair points 1. Spindle case C8955 shovel-type lathe spindle box is split structure. In order to control the deformation of the spindle system within a minimum range, requiring the upper and lower box knot
