摘要
套筒类零件形状精度和位置精度要求较高,孔壁较薄的套筒类零件在加工中容易变形。保证主要表面的位置精度和防止变形,是加工套筒类零件的关键。为加工大直径的套筒类零件设计制造了一种自定心专用夹具,解决了套筒类零件的装夹、定位问题,保证了零件的加工精度,提高了生产效率。
As for the sleeve-type parts, the accuracy of shape and position are highly required. But thin-walled are easy to be deformed. Thus, the insure against deformation for getting high positional major surfaces is the technical key for processing large sleeve-type part. A special self-centering fixture and developed for solving this problem.
