上海市机电制造业在前一时期举办一个规模庞大的庙会,主要是介绍各厂有关机械制造方面的先进经验。我厂也有不少先进的经验在这个会上展出,现在我选一个比较有代表性的夹具——膜片卡盘,介绍给大家参考。这种夹具用来磨削钻套内孔和齿轮内孔能保证有很高的同心度。我们磨外径Ф25公厘、长30公厘的钻套内孔(钻套外圆与端面垂直偏差≤0.01)同心度偏差只有0.005厘,比弹簧夹头的定心精度要高很多。现在分几个部分来谈。
Shanghai Mechanical and Electrical Manufacturing Industry held a large temple fair in the previous period, mainly introducing the advanced experience in machinery manufacturing of each factory. I plant a lot of advanced experience in this meeting on display, and now I choose a more representative of the fixture - diaphragm chuck, introduced to your reference. This kind of fixture is used to grind the inner hole of the drill sleeve and the gear bore to ensure high concentricity. We grind the inner diameter of the drill sleeve with the outer diameter of Φ25 mm and length of 30 mm (the vertical deviation between the outer circumference of the drill sleeve and the end face is less than or equal to 0.01) and the concentricity deviation is only 0.005%, which is much higher than the centering accuracy of the collet. Now talk in several parts.
