机器脚踏车和发动机等的汽缸,工作一定时期后,由于磨擦和其他某些原因,往往不能正常工作,这时就需要进行修理。在修理中,一般用(石享)磨头来磨汽缸内孔,而这类汽缸均带有汽孔,经常使(石享)磨头的油石嵌入汽孔中。这不仅影响加工精度,而且还容易出事故,因此给修磨工作增加了不少困难。本文向大家介绍一个简单的磨具,这是苏联车工福金创造的,这种工具的最大特点是,结构简单,经济适用;只要将它装在车床或钻床上即可磨削,同时也免除了上述的缺点。工真的结构如图所示。它是由夹柄4、销子3、开口销5、木质剖分心轴1、两个相同尺寸的弹簧2及金刚砂布6组成。弹簧是嵌在剖分心轴中 The cylinders of a machine bicycle, an engine, etc., often fail to work properly due to friction and some other causes after a certain period of operation, and repairs are required at this time. In the repair, the general use (stone enjoy) grinding head to grind the cylinder bore, and these cylinders are equipped with steam holes, often make (stone enjoy) grinding head stone embedded in the steam hole. This not only affects the machining accuracy, but also easy to accident, so to the grinding work has increased a lot of difficulties. This article introduces you to a simple abrasive, which was created by Soviet mechanic Fu Jin. The most prominent feature of this tool is that it has a simple and economical structure; it can be grinded just by loading it on a lathe or a drilling machine, The above shortcomings. The real structure as shown. The utility model is composed of a clamping handle 4, a pin 3, a cotter pin 5, a wood splitter mandrel 1, two springs 2 of the same size and emery cloth 6. Spring is embedded in the split mandrel
