车床上的三爪卡盘,经过频繁使用后,会出现喇叭口或工件夹紧时与主轴不同心的现象,需经常进行修复。为此,我们利用现有的工具磨电动机和外圆磨床内圆磨具,设计了一套三爪卡盘修复磨具(见图a)。为解决三爪卡盘三个爪的定位夹紧,还采用了一个弹性卡套(见图b、c)。这套磨具和弹性卡套,制造简单、操作方便、性能可靠。卡爪修复后的效果,基本达到新三爪卡盘的精度。 1.磨具的工作原理 先把车床上的小拖板拆掉,将组装调整好的磨具用T型螺栓9牢固地安装在车床的拖板上,并调整接
Three-jaw chuck on the lathe, after frequent use, there will be a bell mouth or workpiece clamping spindle with different heart phenomenon, the need for regular repair. To this end, we use the existing tool grinding motor and cylindrical grinder internal circular grinding machine, designed a three-jaw chuck repair abrasive (see Figure a). In order to solve the three claw chuck claw positioning clamped, but also the use of a flexible sleeve (see Figure b, c). This set of abrasive and elastic card sets, manufacturing simple, easy to operate, reliable performance. Claw repair effect, basically reached the accuracy of the new three-jaw chuck. 1. The working principle of the abrasive First remove the small carriage on the lathe, the assembly of a good grinding wheel with T-bolts 9 securely mounted on the lathe carriage, and adjust the connection
