这种夹紧套采用青铜或氮化钢制成。在其壁上开有若干纵向切口,以增加夹紧套的弹性变形。在外壁上涂有一层聚酸胺,把切口盖封。在夹紧套的两端设有O形密封环。当向密封腔通入压力油时,夹紧套由于纵向切口而被压缩变形,产生径向夹紧力,将工件夹紧。这种夹紧套有下列优点:
This clamping sleeve is made of bronze or nitrided steel. There are several longitudinal cuts in the wall to increase the elastic deformation of the clamping sleeve. On the outer wall coated with a layer of polyamine, the incision cover. O-rings are provided on both ends of the clamping sleeve. When pressurized oil is introduced into the hermetically sealed chamber, the clamping sleeve is compressed and deformed by the longitudinal incision, creating a radial clamping force that clamps the work piece. This clamping sleeve has the following advantages:
