曲轴车床
<DIV> 曲轴车床是用来加工内燃机及空气压缩机曲轴的连杆颈及曲臂侧面的专门化车床。由于曲轴本身刚度较差，曲轴连杆颈与曲轴回转线不重合，且曲轴颈方位角不同，曲轴车床与一般车床相比有如下特点： <BR> （1）采用特殊卡盘，这种卡盘除具有一般卡盘的夹头外，还带有调整偏心量及方位角的功能（见图8-5）。卡盘1装在机床主轴上，滑台2可在卡盘体1的径向导轨上移动，以调整偏心量e，夹头3夹持工件，并可绕自己的轴线回转，调整方位角。 <BR> （2）两端驱动，机床左右两端带有相同的主轴箱，夹持曲轴两端同步驱动，以减少曲轴在切削过程中的扭转变形。 <BR> （3）多刀加工半自动循环，为了提高生产率，曲轴车床一般具有前后刀架，同时加工连杆颈及曲臂侧面。机床起动后自动进行加工，加工完毕自动停车。</DIV><DIV>
