合肥矿山机器厂金工二车间,原来对图1所示笨重零件的A面,是在普通钻床上将工件翻转过来,采用反刮的方法进行加工。这种加工方法,不仅劳动强度大,而且由于生产效率低,经常影响装配任务完成。为此,工人师付改革了图2所示的电钻刮平面工具。采用此工具,以圆柱1在孔中定位,可直接从 Hefei Mining Machinery Works metalworking two workshops, the original shown in Figure 1 bulky parts of the A side, is in the ordinary drilling machine to flip over the workpiece, the use of anti-scratch method for processing. This processing method, not only labor-intensive, but also because of the low efficiency of production, often affect the completion of assembly tasks. To this end, workers pay to reform the electric drill scraping plane shown in Figure 2 tools. With this tool, positioning the cylinder 1 in the hole can be done directly
