我厂在技术革新中,参考了苏联1K62车床,设计了一种如图所示的连接器,它可将 钻头的尾架与走刀机构的溜板箱联成一休,工作时,只要用销钉将件1与件2连接起来,尾架即可利用拖板纵向走刀机构进行自动钻孔。为了避免因切削力突然增大而损坏机床,我们把销钉当作保险装置,其直径为8公 I plant in technological innovation, with reference to the Soviet Union 1K62 lathe, designed a connector as shown in the figure, which can drill the tailstock and slide the knife body together into a break, work, as long as the pin The pieces 1 and 2 connected, the tailstock can be used vertical slide plate body walk mechanism for automatic drilling. In order to avoid damage to the machine due to a sudden increase in cutting force, we regard the pin as a safety device with a diameter of 8
