摘要
针对环形薄壁件在加工过程中易发生变形、表面粗糙度及内外圆同轴度不易保证的加工难题,设计了相应的辅助定位工装。给出了零件的结构及材料,简述了工装的设计思路,列出了工装结构图及装夹定位图,指出了工装使用的注意事项,论述了工装产生的经济效益。结果表明,该工装的结构简单、加工方便,能可靠定位零件的外圆和内孔,有效保证了零件内外圆的同轴度及表面粗糙度,提高了零件的加工质量,为加工环形薄壁件提供了一个可借鉴的工装设计方案。
In view of the annular thin-wall pieces found in processing process with easy deformation, and the surface roughness with the internal and external circular coaxial degree is not easy to guarantee the processing problems, the corre- sponding auxiliary positioning jig is designed. Introduce the structure and material of parts, the design of tooling. List the tooling structure and the clamping location map. Point out that the tooling considerations, tooling to produce economic ben- efits. The results show that the equipment is in the simple structure and the convenient processing, can realize the reliable positioning components of the outer circle and inner hole, effectively guarantee the parts inside and outside circular coaxial degree and the surface roughness, improve the machining quality of parts for processing, and can be drawn lessons from annular thin-walled package providing a tooling design.
