在未定型产品的生产或试制中,经常有一些非标准的橡胶密封圈和纸板密封垫需要自制。这些形状、尺寸各异的密封圈、垫以前通常用手工剪制,既麻烦又不易保证质量,碰到尺寸小的密封圈就更困难了。为此,我们设计了如图所示的“密封圈切割工具”。该工具是以台钻作动力,转动轴5安装在钻夹头上,当起动台钻时,悬臂6随转动轴5一起转动,悬臂6通过螺钉4紧固在悬臂的V形槽中,该槽能保持悬臂6不在转动轴的孔中转动,但可滑动,悬臂上标有刻度,以确定所需切割密封圈、垫的尺寸,在悬臂6的一端有一用紧定螺钉2通过V形槽定位并紧固的刀架A,刀架A向内弯曲,为便于切割小直径的密封圈,割刀是装在刀架的凹槽内,用螺钉紧固。在悬臂 In the production of unfinished product or trial, there are often non-standard rubber seals and cardboard need to homemade. These seals, which are different in shape and size, are usually manually cut beforehand, which is troublesome and difficult to guarantee the quality. It is even more difficult to hit a small size seal. To this end, we have designed a “ring cutting tool” as shown in the picture. The tool is powered by a bench drill, and the rotary shaft 5 is mounted on the drill chuck. When the bench drill is started, the cantilever 6 rotates together with the rotary shaft 5, and the cantilever 6 is fastened in the V-shaped groove of the cantilever by the screw 4 The slot can keep the cantilever 6 from rotating in the hole of the rotating shaft, but can slide. The cantilever is marked with a scale to determine the size of the required cutting ring and pad. At one end of the cantilever 6, there is a set screw 2 to pass through the V-shaped slot Locating and tightening toolholder A, toolholder A bends inwardly. To facilitate the cutting of small diameter seals, the knife is mounted in the groove of the toolholder and screwed. In the cantilever
