车工在机床上装卸工件时,要用手推拉尾座,每班生产少则数百次,多则千次以上,十分费力(据测定普通车床尾座滑动摩擦拉力在15公斤以上)。 去年,我厂三车间革新组在C616车床上,经过反复试验,制成了气垫尾座。在尾座的鞍板上钻直径为5毫米的孔及通道,如图1所示(包括气路)。外部接上 When lathe loading and unloading workpieces on a machine tool, the tailstock should be pushed and pulled by hand. As much as several hundred times per shift, as many as a thousand times, laboriously is required (the sliding lathe tail tension of the ordinary lathe is determined to be more than 15kg). Last year, I workshop three workshop innovation group in the C616 lathe, after repeated tests, made of the air-cushion tailstock. Drill holes and channels of 5 mm in diameter on the saddle plate of the tailstock as shown in Figure 1 (including gas path). External connection
