我厂生产的气缸活塞所用O形橡胶密封圈系为外购件。由于飞边过大,错模严重,使实际外径增大,致使活塞无法装入气缸,严重影响装配及使用,并增加钳工修理。为此,制造个磨O形橡胶密封圈外飞边的工具,将飞边过大,错模严重的密封圈装夹在夹具中(如图示),利用密封圈两侧完好的圆弧作定位基准,稍稍夹紧即可。在工具磨床上用圆弧成形砂轮把外飞 The O-ring used in cylinder piston produced by our factory is purchased parts. As the flash is too large, the wrong model is serious, the actual diameter increases, resulting in the piston can not be loaded into the cylinder, seriously affecting the assembly and use, and increase fitter repair. To this end, the manufacture of a grinding O-shaped rubber seal outside the flash tool, the flash over, the wrong model is a serious seal in the fixture (as shown), the use of both sides of the ring for a good arc Positioning, a little clamping can be. In the tool grinder with the arc forming grinding wheel to fly
