尾架是车床主要部件之一,它与主轴端顶尖或卡盘配合使用,支承被加工零件。如C620-1类型车床,由于零件装卸频繁,顶尖套在尾架孔内轴向往复移动的频率较高,又因尾架顶尖套表面外露容易积有灰砂,致使尾架孔拉毛及磨损,所以在车床大修时,多半需更换顶尖套,修复尾架孔。修复的方法一般采用研棒和研磨剂通过人工进行研磨,以恢复孔的精度。这种方法劳动强度高、工效低,且材料浪费。针对上述情况,我们利用车床本身的结构特点,采用了一种简易的专用工具,即车床尾架孔自珩磨工具,
The tailstock is one of the major components of a lathe. It cooperates with the spindle nose or chuck to support the machined part. Such as the C620-1 type lathe, due to frequent loading and unloading parts, the top set in the tailstock hole axial reciprocating frequency higher, because the end of the tail sleeve tip surface easy to accumulate gray sand, causing the tailstock hole hair and wear, So overhaul the lathe, most need to replace the top cover, repair tail hole. Repair methods are generally used to grind the grinding rod and grinding agent to restore the accuracy of the hole. This method of labor-intensive, low efficiency, and material waste. In view of the above situation, we use the structural characteristics of the lathe itself, using a simple and special tools, lathe tail hole self-honing tools,
