为了提高生产率和产品质量,我厂和广州机电研究所、华南工学院一起设计了490柴油机缸体自动线,并于1978年下半年完成了该线的制造、调试及试投产工作。试产结果证明产品质量符合图纸要求后,即进行小批投产。现将其简介如下:一、用途该自动线用于加工490柴油机缸体两端面。可完成精铣两端面,钻两端面所有各孔,钻、扩、铰定位销孔,粗扩凸轮轴孔和粗镗主轴孔等工序。经自动线加工后的另件,要求能达到图纸所规定的尺寸精度和光洁度(参见图18)
In order to improve productivity and product quality, I plant and Guangzhou Institute of Electrical and Mechanical Engineering, South China Institute of Design 490 automatic diesel engine cylinder line, and in the second half of 1978 completed the manufacture of the line, commissioning and commissioning work. Pilot results show that product quality in line with the drawings, that is, a small batch of production. Now its profile is as follows: First, the use of the automatic line for processing 490 Diesel engine cylinder both ends. It can finish the processes such as fine milling both end surfaces, drilling all the holes on both ends, drilling, expanding and reaming pin hole, roughing and expanding axle shaft hole and roughing spindle hole. After the automatic processing of the other pieces, required to achieve the dimensional accuracy of the drawings and finish (see Figure 18)
