我厂车工崔作斌老师傅,利用C620-1车床,改进一种自动进刀加工内外圆弧面的工具,用来加工汽门圆弧面及内燃机预燃室喉管的内球面,解决了光洁度及精度的关键问题,使质量大大提高,并为加工内外圆弧面工件实现专业化生产开辟了道路。现介绍如下,以供参考。一、结构及其传动将车床溜板箱的小刀架及小横絲杆的螺母拆去,以免小拖板沿着燕尾槽滑行,然后装上蜗轮4和蜗杆14(见图1)。齿轮11装在溜板箱横絲杆的端头,小齿
I plant mechanic Cui Zuobin master, the use of C620-1 lathe, an automatic tool to improve the processing inside and outside the arc surface tool used to process the arc surface and internal combustion engine pre-combustion chamber throat tube to solve the finish and Accuracy of the key issues, so that greatly improve the quality and processing of internal and external circular arc workpiece to achieve the specialized production opened up a path. Now introduced as follows, for reference. First, the structure and its transmission Lathe skid cutter holder and a small crossbar nut removed, so as not to drag the small drag along the dovetail slot, and then mounted on the worm gear 4 and worm 14 (see Figure 1). Gear 11 is mounted on the end of the screw box slide screw rod, small teeth
