近日,上海市计量测试技术研究院设计了一套涡轮部件及螺柱标准件同轴度测量检具,能够对没有顶尖孔的涡轮部件和螺柱标准件螺纹的中径位置和圆柱部分的同轴度进行测量,技术指标达到国际先进水平,已申请发明专利一项。在机动车制造业,涡轮部件及螺柱标准件是涡轮增压器与变速箱中的关键部件,对其尺寸的精度要求很高。涡轮部件螺纹的中径位置和圆柱部分的同轴度对保证涡轮增压器的密封性有很重要的作用。在变速箱装配过程中,螺柱标准件的应用十
Recently, Shanghai Institute of Measurement and Testing Technology designed a set of turbine components and stud standard parts concentricity measurement gages, turbine parts without top holes and stud standard parts thread diameter position and cylindrical part of the same Axis to measure, technical indicators have reached the international advanced level, has applied for a patent. In the automotive industry, turbine components and stud standard parts are key components in turbochargers and gearboxes, requiring high dimensional accuracy. The centerline diameter of the turbine component thread and the concentricity of the cylindrical portion are important to ensure the tightness of the turbocharger. In the gearbox assembly process, stud standard parts of the application of ten
