像图中那样的止回阀,阀体上有一个72°的斜阀面。这个阀面过去只能由钳工用凿子来凿,然后再用刮刀刮平,这样很费工、费料。我厂工人改进了一个工具,把它装在钻床上来加工斜阀面,效率比原来提高好多倍,质量好。这种工具的构造和使用情况如下:构造——如附图,1是止回阀本体,里面有一个倾斜成72°的阀面。2是工具的本体,是承放转轴用的。3是转轴,可以和钻床上的钻轴配合,它的下端有一个小齿轮4。5是大齿轮的心轴和刮排。6是大齿轮。7是铜轴承和进刀拨
Check valve as the figure, the valve body has a 72 ° oblique valve surface. In the past, this valve surface could only be chiselled by a fitter with a chisel and then scraped with a scraper, which was laborious and costly. I plant workers to improve a tool, put it in the drilling machine to process oblique valve surface, the efficiency is improved many times higher than the original, good quality. The construction and use of this tool is as follows: Construction - As shown in the drawing, 1 is the check valve body with a valve face tilted at 72 °. 2 is the body of the tool is used to support the shaft. 3 is the shaft, which can be matched with the drill shaft on the drilling machine. It has a pinion at the lower end. 4.5 is the spindle and scraper of the large gear. 6 is a big gear. 7 is a copper bearing and feed dial
