随着粘接技术的推广应用,为克服套类零件的装配变形,采用间隙配合粘接衬套与本体的方法取代过盈配合的联接,取得了良好效果,特别是在工具设计中应用较为广泛。我厂较大孔的社套与本体之间的联接,均采用这种方法。但是衬套与本体粘接固化后,具有一定的应力和强度,周期性更换衬套比过盈配合困难得多,即使用专用工具拆换也很困难,而且由于 With the popularization and application of bonding technology, in order to overcome the deformation of the assembly of the sleeve parts, the method of using the gap fitting and bonding the bushing and the body instead of the connection of the interference fit has achieved good effect, especially in tool design . I plant a larger hole in the community between the body and the connection, are using this method. However, after the bushing and the body are bonded and cured, the bushing has a certain degree of stress and strength. It is much more difficult to replace the bushing periodically than the interference fit. Even if the special tool is used, it is difficult to replace the bushing.
