把图1的机械研磨夹具,装在普通车床刀架上,加工大型零件,可以获得很高的表面光洁度。这种研磨夹具的特点加图2所示。工作时,工件转动而磨条作“轴(?)振动”,因此可以得到很高的表面光洁度。夹具的结构如图3所示,底座5上装有功率为0.6瓩、转速为1440转/分的电动机15、支持皮带轮的角铁4、以及装有齿条的底板7和夹具体10。主轴1贯通夹具体10和角铁4,装在套筒2内。主轴端头有偏心孔,偏心转21装 The mechanical grinding fixture in Figure 1, mounted on the ordinary lathe turret, processing large parts, you can get a high surface finish. The characteristics of this grinding fixture plus Figure 2 shows. Work, the workpiece rotation and grinding for the “shaft (?) Vibration”, so you can get a high surface finish. The structure of the clamp is shown in FIG. 3, the base 5 is equipped with a motor 15 having a power of 0.6 瓩, a rotational speed of 1440 rpm, an angle iron 4 supporting the pulley, a rack 7 and a clamp body 10. The main shaft 1 penetrates the clamp body 10 and the angle iron 4, and is installed in the sleeve 2. Spindle end eccentric hole, eccentric rotation 21 installed
