我市某厂加工速接管件时，在普遍车床上用常规方法完成车外圆及切槽工序。由于刀具的重复移动和定位，不仅难于保证零件的尺寸要求，而且也增加了加工中的辅助时间，同时，机床导轨早早出现局部磨损也是一个不可忽视的问题。为此，我们设计出一种联动进给机构固定于车床导轨面 When a factory in our city takes over the processing of high-speed pipe fittings, the car’s outer circle and grooving process are completed by the conventional lathe. Due to the repeated movement and positioning of the tool, it is not only difficult to ensure the dimensional requirements of the part, but also the auxiliary time during machining. At the same time, the local wear of the guide rail of the machine tool is also an issue that can not be neglected. To this end, we designed a linkage feed mechanism fixed to the lathe rail surface
