最近我们在试制一种新的液压换向阀时,由于没有专用的加工机床,加上这种阀质量及体积均比老产品大一倍以上,若采用传统的装夹和加工方法来加工阀孔,则显得劳动强度大,生产效率低。为此,我们采用了一种新的加工方法,不仅可减轻操作者劳动强度,而且加工出的阀孔精度也普遍提高,为后面工序的进行创造了有利条件。 1.加工原理及夹具结构 传统的加工阀孔工艺是将工件装夹在装有车床夹具的车床主轴上,刀具分别装于刀架或尾架上,通过
Recently when we trial a new type of hydraulic valve, because there is no dedicated processing machine tools, coupled with the quality and volume of such valves are more than double the size of the old products, if the use of traditional clamping and machining methods to process the valve Hole, it seems labor-intensive, low productivity. To this end, we have adopted a new processing method that not only relieves the operator’s labor, but also improves the accuracy of the machined valve hole, creating favorable conditions for the subsequent process. 1. Machining principle and fixture structure Traditional machining valve hole process is the workpiece is mounted on the lathe spindle equipped with a lathe fixture, respectively, the tool is mounted on the turret or tailstock, by
