洗涤机外壳的加工,最后一道工序是镗孔和车端面,这是最关键的一道工序。同心度要求很高,而且要求孔的中心线与凸台B相垂直。我们是用附图所示出简易镗床来加工的。镗孔时,4块分件组合成一个整体,全高4200公厘,宽3000公厘左右,孔心离地面为2500公厘。这样大的工件即便在重型镗床上加工,也需要特殊的辅助工具。由于工件形状夏杂,中间孔径很大,而端面孔径很小,所以调整比较麻烦,生产效率不高。而且,由于孔长
Washing machine shell processing, the last process is boring and car end face, this is the most critical one process. Concentricity is very demanding, and requires that the centerline of the hole be perpendicular to the boss B. We are using the diagram shown in the simple boring machine to process. Boring, the four components combined into a whole, the total height of 4200 mm, 3000 mm wide, hole heart from the ground to 2500 mm. Such a large workpiece even in the heavy boring machine processing, also need special aids. Due to the shape of the workpiece Xia, the middle aperture is large, and the end surface aperture is small, so the adjustment is too much trouble, the production efficiency is not high. Moreover, due to the long hole
