我厂产品6吨矿车上刹车部分的一个零件——齿钩(见附图的工件7),厚16毫米,需要加工上下两平面和一个孔,工艺虽然简单,但因该零件是带有曲面的,有凸出的圆弧,用老虎钳不易轧紧,铣不平。后来经我厂的工人同志开动脑筋,制成一只如附图所示的夹具,可以六只工件一次铣加工,既平整又方便,需时仅5分钟,加工质量亦达到要求。今后如能改用两块动块,则效果更好。 One of the parts of the brake on the 6 tonne car of our factory, tooth hook (see the picture 7), 16 mm thick, need to process two planes and one hole. The process is simple, but because the part is with Surface, convex arc, not easy to use the vise tight, milling uneven. Later, the factory workers comrades brains to create a fixture as shown in the drawings, can be a milling of six parts, both smooth and convenient, take only 5 minutes, processing quality also meet the requirements. If you can switch to two moving blocks in the future, the effect is better.
