补充资料:工件安装及所用附件
在车床上安装工件所用的附件有三爪卡盘、四爪卡盘、顶尖、花盘、心轴、中心架和跟刀架等。安装工件的主要要求是位置准确、装夹牢固。
一、三爪卡盘安装工件
三爪卡盘是车床上应用最广的通用夹具,适合于安装短圆棒料或盘类(直径较大的盘状工件中,可用反三爪夹持)工件,它的结构见示范教具。当转动小伞齿轮时,大锥齿轮便转动,它背面的平面螺纹就使三个卡爪同时向中心靠近或退出,以夹紧不同直径的工件。三爪卡盘装夹方便能自动定心,但其定心准确度不高,约为0.05~0.15mm。工件上同轴度要求较高的表面应在一次装夹中车出。
二、四爪卡盘安装工件
四爪卡盘的结构见直观教具。四爪卡盘有四个互不相关的卡爪,各卡爪的背面有一半瓣内螺纹与一螺杆相啮合。螺杆端部有一方孔,当用卡盘扳手转动某一螺杆时,相应的卡爪即可移动。如将卡爪调转180°安装,即成反爪。
四爪卡盘由于四个卡爪均可独立移动,因此可安装截面为方形、长方形、椭圆以及其它不规则形状的工件。同时,四爪卡盘比三爪卡盘的夹紧力大,所以常用来安装较大的圆形工件。
由于四爪卡盘的四个卡爪是独立移动的,在安装工件时须进行仔细的找正工件,一般用划针盘按工件内外圆表面或预先划出的加工线找正,其定位精度较低,为0.2~0.5mm。用百分表按工件精加工表面找正,其定位精度可达0.02~0.01mm。
