当前,焊接机器人的重复精度通常已达到±0.002英寸(0.05毫米)。然而,如果被焊接的工件是非重复的,或者夹具达不到如此的精确程度,那又怎么办呢?如在Norfolk ＆ Western铁路公司的车辆修理厂,修理的零部件出自各个不同的制造厂家,没有两个零件的形状是完全相同的,而且小零件也有1100磅(500公斤)重。 NW铁路公司用避开这些问题的办法来解决它们。利用由用由计算机控制的焊接机器人研制中的最新成就,通过传感器和一些软件,并且安装了一台带两只电视摄像机“眼睛”的Automatix公司制造的焊接机器人,无论夹具将工件送到什么位置,也不论
Currently, welding robot repeatability is usually up to ± 0.002 in. (0.05 mm). However, what if the workpieces to be welded are non-repetitive or if the fixtures do not reach such precision? For example, at the Norfolk & Western Railway Vehicle Repair Shop, the repaired parts came from various manufacturers, No two parts are exactly the same shape, and small parts are also 1100 pounds (500 kg) weight. NW Railway solved these problems by avoiding them. Using the latest achievements in the development of welding robots controlled by computers, through sensors and some software, and the installation of a welding robot made by Automatix with “eyes” of two television cameras, no matter where the jigs are to send the workpieces No matter
