1、 毕业设计（论文） 液压三爪卡盘 学生姓名 系（部） 机械工程系 专 业 数控技术 指导教师 2010 年 5 月 31 日 I 摘摘 要要 本论文设计一种在三爪卡盘上加装摆动式液压缸和平面螺旋机构的螺旋摆动式液 压缸增力机构的结构。传统的机床如车床、铣床上三爪卡盘的工作一般依靠工人用手工进行 夹紧,这不但增加了工人的劳动强度，而且所需夹紧力非常大,还常常有夹不紧的情况，阻碍了 生产率的提高。通过在三爪卡盘加装摆动式液压缸和平面螺旋机构构成螺旋摆动式液压缸增 力机构，可实现与原有卡盘体的较好结合,并使外加压力能转换成圆周运动,且其结构简单,工 作可靠,能达到较高的增力比，具有良好的经济性和可行
