摘要
某型号节流圈,其结构特点是壁薄,壁厚仅2.5mm,轴向尺寸小,精度高,刚性差;加工难点为装夹时容易变形,尺寸精度难以保证。通过设计、制作专用夹具,优化加工参数,解决了这一加工难题。这样既保证了产品质量,降低了加工难度又显著提高了生产效率。
Structural feature of throttle ring are thin wall part （wall thickness 2.5 mm）,short axial dimension, high dimension precision and poor rigidity. Difficult point of machining are easy deformation when installing jig and difficult to ensure the dimension precision. After the problems are solved by design, making special jig and optimizing working parameters, the product quality and productive capacity are increased greatly. The method of installing jig gives a reference to similar thin wall working.
