在机械加工中,零件的吊装也是重要的问题,特别是中型零件,灵活地吊装,既可以缩短辅助时间,提高劳动生产率,又可以大大减轻工人的体力劳动。我厂有些车间的生产线采用了如图所示吊装工具。此吊装工具结构简单、制造容易、使用方便灵活,深受工人欢迎。特别是吊装六棱八角的零件(十几公斤左右),更体现其优越性。使用时耳环1钩挂在专用吊装设备上(如电葫芦、气缸等),滑套3以其孔的长方形槽与下钩4配合,
In machining, hoisting parts is also an important issue, especially medium-sized parts, hoisting and flexible, can shorten the auxiliary time, improve labor productivity, but also can greatly reduce the manual labor. Some workshops in our factory use the production line as shown in the lifting tool. The hoisting tool has the advantages of simple structure, easy manufacture, convenient and flexible use and high worker’s welcome. In particular, lifting the hexagonal octagonal parts (about ten kilograms), but also reflects its superiority. When used, the earring 1 is hooked on a special hoisting device (such as an electric hoist, an air cylinder, etc.). The sliding sleeve 3 cooperates with the lower hook 4 through the rectangular slot of the hole,
