平面磨床磨头采用转子轴与砂轮轴为一体的结构。这种结构维修比较麻烦,因为电机轴和砂轮轴为一体,不管电机或主轴哪一部位出现故障,都必须将各部件拆下,进行维修,这样必然破坏已调整好的磨头精度,装配时又要重新调整,维修时间长,精度也受影响。为此,我们采用了一种只拆定子,不拆磨头其它零件的方法,修复了M7150磨床。修理方法:1.拆下电机后端盖,取下叶轮和压紧螺母。2.测好定子和电机壳体的相互位置、圆周和深度部位,做好标记,
Surface grinder grinding wheel rotor shaft and wheel shaft as a whole structure. This structure is too much trouble to repair, because the motor shaft and wheel shaft as a whole, no matter what part of the motor or spindle failure, the components must be removed for maintenance, it will inevitably damage the adjustment of the grinding head accuracy, assembly But also to re-adjust, repair a long time, accuracy is also affected. For this reason, we have adopted a method of disassembling the stator and not removing the other parts of the grinding head to repair the M7150 grinding machine. Repair method: 1. Remove the motor rear cover, remove the impeller and compression nut. 2. Good test stator and motor housing mutual position, circumference and depth of the site, make a mark,
