摘　　要：针对薄壁套筒零件在二次装夹过程中产生的变形问题,设计了一种适用于铣削加工的内撑夹具。介绍了该夹具的工作原理和操作方法,对该夹具进行定位误差分析,计算出铣削过程中的切削力,然后利用CATIA软件对夹具体建模,并对主胀紧装置进行有限元分析。结果表明:该夹具满足设计要求,在生产实践中具有参考价值。In view of the deformation of thin⁃wall sleeve parts during the secondary clamping process,an internal support fixture suitable for milling was designed.The working principle and opera⁃tion method of the fixture was introduced.The positioning error of the fixture was analyzed,and the cutting force in the milling process was calculated.Subsequently the CATIA software was used to model the clamp body and carry out a finite element analysis on the main expansion device.Results show that the fixture meets the design requirement and has reference value in practical production.
