我厂在高压电机生产中遇到了轴上键槽(图1)加工的困难。由于工件长(2.3m),键槽规格、数量多,且工件中部有一特长键槽,在已有设备上加工存在的问题是:①需要人工对中;②设备行程短,工件需要多次装夹。因此,生产率极低,加工质量亦受操作者个人因素的影响。 在生产批量不大的情况下,购买适用的标准键槽铣床显然不经济。为此,
I plant encountered in the production of high-voltage shaft shaft keyway (Figure 1) processing difficulties. As the workpiece length (2.3m), the keyway specifications, the number of large, and the middle of the workpiece has a keyway, in the existing equipment processing problems are: ① manual alignment; ② equipment, short stroke, the workpiece requires multiple clamping. As a result, productivity is extremely low and the quality of the workmanship is also influenced by the personal factors of the operator. In the case of production is not large, the purchase of the applicable standard keyway milling machine is obviously not economical. to this end,
