摘　　要：阀杆在整个喷油器当中至关重要,其外圆表面质量,直接影响整个喷油器的装配和喷油器性能。针对阀体外圆成形磨削中出现的质量问题,通过建立磨削加工系统的力学模型,对导轮、工件进行了受力变形分析,揭示了影响阀杆外圆表面磨削质量的主要因素并提出了工艺改进措施。通过理论分析了工件在砂轮磨削力下产生的变形对磨削加工质量的影响,建立了力学补偿模型来补偿砂轮磨削力引起的变形,并结合实验验证了理论分析的正确性和和工艺优化的有效性。Valve piston is significant in injector whose quality problem will affect the function of injector directly.Especially,some external cylindrical quality problem can influence the assembling line and the quality of injector.Its production is based on external cylindrical grinding process.Analyzes the mechanical model and figures it out to find out the best position of the fixation system to guarantee the quality and productivity.Analyzes the deformation of valve piston under the grinding force and establishes the mechanical compensation model.A lot of experiment certify the truth of the analysis and make it available.
