摘要
珩磨工艺是液压油缸缸筒加工的最后一道工序,珩磨加工后因缸筒发热变形给内孔的尺寸检测带来了不利影响。为了保证生产效率和提高缸筒珩磨后的尺寸精度,以臂架缸和输送缸为例,在珩磨机上进行了珩磨热变形规律分析实验,得到了不同缸径、壁厚和温升下的缸筒珩磨热变形数据。结果表明:温升和缸径越大,壁厚越小,热变形越大。
        Honing technology is the last working procedure in the processing of hydraulic cylinder.After honing,the thermal deformation of cylinder has a negative impact on the measurement of inner hole size.In order to ensure the production efficiency and improve the dimensional accuracy of cylinder after honing,taking boom cylinder and conveyor cylinder as examples,the analysis experiment of honing thermal deformation is carried out on honing machine,and the data of honing thermal deformation of cylinder under different cylinder diameter,wall thickness and temperature rise are obtained.The results show that the bigger the temperature rise,the bigger the cylinder diameter,the smaller the wall thickness and the bigger the honing thermal deformation.
