| 摘 要： | 针对分度类零件的加工特点，将普通立式铣床改造为分度类零件加工专用机床，把铣床原丝杠螺母进给传动装置改造成液压传动方式。其分度装置利用步进电机驱动，对F125普通万能分度头进行数控化改造；控制装置采用PLC取代原有的继电器控制。改造后的专用机床对分度类零件可以实现快进-减速快进-工进-快退-减速快退-分度-快进的自动循环加工。通过对矩形齿快慢速转换离合器零件的加工实验证明，该机床加工分度类零件可以提高生产效率、减少操作失误及提高加工精度。

| Abstract: | According to the features of processing indexing parts, the common vertical milling machine for processing machine indexing parts, the milling machine the original screw nut feed drive device with hydraulic transmission mode. The indexing device using step motor drive, the F125 universal dividing head NC transformation; control by the PLC to replace the original relay control. Special machine after transformation of dividing parts can realize fast - speed automatic cycling fast forward - feeding - Fast - slow - fast forward rewind - indexing. Through processing experiment of rectangular tooth speed conversion clutch parts of the proof, the machine indexing part can improve the production efficiency, reduce errors and improve the machining accuracy. |
