偏心套在一般机械产品上,大多是易损零件,因而设备维修时、经常要碰到偏心套的加工问题。在制造厂,由于批量较多,通常都是利用专用夹具进行车、磨等加工。修配中,如果也设计制造专用夹具,显然太不经济,或者在四爪卡盘上经过划线、调整等办法来加工,则不仅费工,而且质量不易保证。尤其是对于精度要求高、需要车、磨等几道工序加工的偏心套, Eccentric sets in general mechanical products, mostly fragile parts, so equipment maintenance, often encounter the processing of the eccentric sleeve. In the factory, due to the large volume, usually using special fixtures for vehicles, grinding and other processing. Repair, if the design and manufacture of special fixtures, obviously too uneconomical, or scribed in the four-jaw chuck, adjustment and other methods to processing, it is not only labor-intensive, but the quality is not easy to guarantee. Especially for the high precision, the need car, mill and other processes of processing eccentric sleeve,
