在制造和修理衡器中,为了解决线纹的刻制问题,我们制造了一台半自动刻线机。它可刻制各种不同间距和长度的线纹,每分钟能刻60～100条线纹,刻完后自动停止,代替了原来在普通机床上的刻线工作,减轻了劳动强度,提高了刻线质量和工效。一、传动原理半自动刻线机的传动原理见图1。电机1通过皮带轮、蜗轮副、离合器传动,使轴24旋转。在传动轴24上装有链轮,通过链传动和刀架偏心轮11、拉杆12使刀架作往复直线运动。在传动轴24的右端装有进给偏心轮25,通过齿条26、齿轮27、28和29、舵盘
In the manufacture and repair of scales, in order to solve the problem of line marking, we have created a semi-automatic groove machine. It can engrave various lines with different pitch and length, can engrave 60 ~ 100 lines per minute, stop automatically after engraving, instead of the original engraving work on ordinary machine tools, reduce the labor intensity and improve the Scribing quality and ergonomics. First, the transmission principle Semi-automatic groove machine transmission principle shown in Figure 1. Motor 1 through the pulley, worm gear, clutch drive, so that shaft 24 rotation. A sprocket is mounted on the transmission shaft 24, which reciprocates the linear movement of the tool holder through the chain transmission and the eccentric 11 of the tool holder. At the right end of the drive shaft 24 is mounted a feed cam 25 which, via a toothed rack 26, gears 27, 28 and 29,
