摇臂轴座加工自动线建成于1974年,投产使用证明性能良好。全线仅需一人操作。与通用机床加工相比,原需13个小时的工作量现用15分钟即能完成。一、被加工零件摇臂轴座是16V240Z柴油机上的一个零件,其材料为HT20-40铸,外形较复杂,主要加工部位如下: 1.上下两个平面,距离195毫米,光洁度要求▽4。 2.两个φ50D_b孔,分布在两侧,两孔的同轴度要求为0.02毫米,光洁度▽6,端面加工光洁度为▽4。
Rocker arm axis processing automatic line was built in 1974, put into operation proved good performance. Only one person across the board. Compared with general-purpose machine tool processing, the workload of 13 hours actually takes 15 minutes to complete. First, the processed parts Rocker shaft seat is a 16V240Z diesel engine parts, the material is HT20-40 cast, the shape is more complex, the main processing parts are as follows: 1. Up and down two planes, a distance of 195 mm, finish requirements ▽ 4. 2. Two φ50D_b holes, distributed on both sides, the coaxiality requirements of the two holes is 0.02 mm, finish ▽ 6, the finish of the end surface is ▽ 4.
