生产鲍尔格——华尔纳(Borg—Warner)45型汽车变速箱的一项主要专用设备是一条加工主箱体的大型自动线。与生产主箱体有关的全套设备的总成本约计一百万英镑。美国的兰姆(Lamb)公司在加拿大制造的这条带有随行夹具的自动线共有三十七个工位。图1左面为两个已经清铲干净的主箱体铸件,但还未加工,正准备装到兰姆自动线上进行加工。这条自动线除了不切除三个小的辅助凸缘外,用于完成箱体的全部工序,使箱体加工到如图1右面所示的两个箱体一样。全部工序完成以后,箱体从自动线末端输出,每隔21.5秒输出一件。
A major special equipment for the production of the Borg-Warner 45-type automotive transmission is a large automatic line for the main box. The total cost of a complete set of equipment related to the production of the main box is about £ 1 million. The 37-station automatic line with accompanying fixtures made by a Lamb company in the United States has a total of 37 stations. The left side of Figure 1 has two clean shovel main box castings, but not yet processed, is preparing to load on the Lamb automatic line processing. In addition to not removing three small auxiliary flanges, this automatic line is used to complete the process of the box so that the box is machined to the two boxes shown on the right of Figure 1. After all the processes are completed, the box is output from the end of the automatic line, outputting one piece every 21.5 seconds.
