这条轴箱体加工自动线是我厂职工和湖南大学师生一起设计,由我厂制造、安装和调试成功的。它用于加工货车新转8型轴箱体,能完成导框、圆凸台、斜口、钻孔和攻丝等全部加工工序。自动线于1970年投产,使用情况良好。轴箱体的材料为ZG15,硬度为HB150～170,净重55公斤。加工时,以内导框和圆凸台内壁为定位基准。加工好的轴箱体达到图1要求的尺寸精度和光洁度,并符合如下技术要求: 1.轴箱两侧导框中心的偏差不超过1毫米; 2.轴箱顶部内壁至外部支承面的厚度,
This axis box processing automatic line is my factory workers and teachers and students in Hunan University design together, manufactured by our factory, installation and commissioning success. It is used to process the new type of axle box body of the truck and can complete all machining processes such as guide frame, circular boss, beveling, drilling and tapping. Automatic line put into operation in 1970, in good condition. The material of axle box body is ZG15, the hardness is HB150 ~ 170, the net weight is 55 kilograms. Processing, the guide frame and the inner wall of the circular boss for the positioning of the benchmark. The machined shaft box achieves the dimensional accuracy and finish required in Figure 1 and complies with the following technical requirements: 1. The deviation of the guide frame center on both sides of the shaft box does not exceed 1 mm. 2. The thickness of the inner wall of the top of the shaft box to the outer support surface ,
