There exists a situation of large fluctuation in clamping force while the vice jaw opening of clamping mechanism has rather large variations on account of clamping large-scaled work-pieces of different dimensions, therefore it is very difficult to ensure the reliability of clamping or even causing failure on the function of clamping mechanism. The processing method and jig designing process of some cylinder body were introduced. In the processing of thin wall cylinder components, they are easy to distort, so it is very difficult to guarantee the precision. At last，technology analysis is very important, on the basis of analyzing technologies of shaft components NC processing, the methods of usual components NC processing technologies were given out, which was significant for actual manufacture and enhancing products quality. Keywords：clamping force；Clamping devices；processing craft designing；shaft components process 目 录 TOC \o 1-2 \h \z \u HYPERLINK \l _Toc294287351 摘 要 PAGEREF _Toc294287351 \h I HYPERLINK \l _Toc294287352 ABSTRACT PAGEREF _Toc294287352 \h II HYPERLINK \l _Toc294287354 1 前言 PAGEREF _Toc294287354 \h 1 HYPERLINK \l _Toc294287355 1.1 起重夹钳国内外发展情况 PAGEREF _Toc294287355 \h 1 HYPERLINK \l _Toc294287356 1.2 起重夹钳加工的发展情况 PAGEREF _Toc294287356 \h 3 HYPERLINK \l _Toc294287357 1.3 研究的主要内容及解决的主要问题 PAGEREF _Toc294287357 \h 3 HYPERLINK \l _Toc294287358 2 100KG起重夹钳装置机构原理和作用 PAGEREF _Toc294287358 \h 4 HYPERLINK \l _Toc294287359 2.1 100KG起重夹钳装置机构的结构 PAGEREF _Toc294287359 \h 4 HYPERLINK \l _Toc294287360 2.2 100KG 起重夹钳装置机构的基本原理 PAGEREF _Toc294287360 \h 5
