三爪卡盘螺旋式摆动液压缸增力机构的设计.docx

摘要 本论文设计一利I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、铳床上三爪卡 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丿艮缸和平面螺旋机构构成螺旋摆动式液床 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 的经济性和可行性。 关键词：三爪卡盘，液压缸，夹具，增力 Abstract This paper design a 3 Java Card the installation of the swing hydraulic pressure tank peace side spiral the spiral swing hydraulic pressure tank increased power structure. Traditional machine tools such as lathes. Miller, Chuck 3 Claws of workers in general rely on a manual for gripping, this will not only increase the intensity of the work of the workers, and the required gripping power is very great, but also a folder is not immediately are often the case, hinder the increase in productivity. The 3 Claws chuck the installation of the swing hydraulic pressure tank peace side spiral institutions constitute a spiral swing hydraulic pressure tank increased authority to achieve the original chuck the better, and the additional pressure can be converted into a circular movement and the simple, reliable, can achieve a higher increase to more than a sound economic and practical.
