5、钻孔的主要车床附件。数控车床的尾座是在加工轴类零件时，使用其顶尖顶紧工件，保证加工的稳定性。尾座的运动包括尾座体的移动和尾座套筒的移动。主要是螺旋机构。1.1.2车床尾座的用途1.尾座套筒的移动是为了使顶尖顶紧或松开工件的，通常是由液压缸控制的。2.车床尾座的作用:车床的尾座可沿导轨纵向移动调整其位置。其内有一根由手柄带动沿主轴轴线方向移动的心轴，在套筒的锥孔里插上顶尖，可以支承较长工件的一端。还可以换上钻头、铰刀等刀具实现孔的钻削和铰削加工。1-后顶尖2-尾座体3-尾座套筒4-手柄5-丝杠6-螺母7-端盖8-手柄9-手轮10-螺母11-拉杆12-压板13-螺栓14-压

7、专用钩。8.用锉刀打光工件，必须右手在前，左手在后；用砂布打光工件，要用“手夹”等工具，以防绞伤。9.一切在用工、量、刃具应放于附近的安全位置，做到整齐有序。10.车床未停稳，禁止在车头上取工件或测量工件。11.车床工作时，禁止打开或卸下防护装置。12.临近下班，应清扫和擦试车床，并将尾座和溜板箱退到床身最右端。第2章车床尾座的拆卸与装配2.1作业前的准备1.拆装车床型号和用具（1）车床：ca6140普通车床（2）工具：内六角搬手壹套、六角搬手一套、活动扳手、螺丝刀、手锤等2.注意事项：（1）看懂结构再动手拆，并按先外后里，先易后难，先下
