摘　　要：以精密衬套为研究对象,采用控制变量法,基于有限元理论仿真,分析滚压参数对滚压力的影响,通过试验研究滚压参数对粗糙度的影响。两种方法均反映出相同规律:过盈量是影响滚压光整效果的关键因素,一定范围内,随着过盈量的增加,衬套内孔表面粗糙度先减小再增加;同一过盈量,滚针数量为6个时,衬套内孔表面粗糙度最小;而滚压速度和进给量对滚压光整效果无明显影响。滚压光整工艺参数的研究为精密衬套的加工提供了参考。Taking precision bushing as the research object,using controlled variable method and finite element theory simulation,the influence of rolling parameters on rolling pressure is analyzed,and the influence of rolling parameters on roughness is studied through experiments.Both methods reflect the same law:the amount of interference is a key factor that affects the effect of roll finishing.Within a certain range,with the increase of the amount of interference,the surface roughness of the inner bore of the bushing first decreases and then increases;the same process when the number of needle rollers is 6,the surface roughness of the inner hole of the bushing is the smallest;while the rolling speed and feed rate have no obvious influence on the rolling finishing effect.The study of rolling finishing process parameters provides a reference for the machining of precision bushings.
