摘　　要：当前国内轴承行业在磨削中使用的偏心夹具,普遍采用通用磨床,利用偏心夹具的本身偏心来使轴承偏心相对应,从而加工出合格的产品,但是偏心夹具本身存在加工困难,重复定位难度较大,加工效率低,工装精度低的问题。文中通过对偏心夹具的改进和优化设计,解决了上述问题,经验证,使用效果良好。At present,the eccentric fixture used in grinding in domestic bearing industry generally works on general grinding machine.The eccentric fixture itself is used to make the bearing eccentric,so as to process qualified products.However,the eccentric fixture itself has some problems,such as processing difficulty,repeated positioning difficulty,low processing efficiency and low tooling accuracy.In this paper,through the improvement and optimization design of eccentric fixture,the above problems are solved,and the application effect is good.
