如图,在套筒件壁上钻小孔Φ_2后,必须去掉它与大孔相贯处A的毛刺。这个“小问题”常令人伤脑筋。因为采用先进的去毛刺方法往往受到设备、成本等条件的限制;手工去毛刺,譬如用刮刀、砂条,又操作困难,效果差,工效低。若采用图中所示的专用工具(件1、2),问题比较容易解决。使用此工具时,先将杆1工插入工件小孔中,然后将刮刀头2的刃部朝向A部,由套筒口放入并套在1杆扁条上,再拉紧杆1,拧
In the figure, after drilling the hole Φ_2 in the wall of the sleeve, it is necessary to remove the burr of the hole A that meets the hole. This “little problem” is often mind-blowing. Because the use of advanced deburring methods are often subject to equipment, costs and other conditions; manual deburring, such as scraper, sand, and difficult to operate, the effect is poor, low efficiency. If you use the special tools shown in the figure (1, 2), the problem is easier to solve. Use this tool, the first rod into the workpiece hole workers first, and then scraper head 2 of the blade toward the A Department, by the sleeve into the port and put a flat rod, and then tighten the rod 1, screw
