CB3463-1半自动转塔车床是一种生产效率比较高的设备。它可以完成产品的钻孔、扩孔、挖内槽以及车削内、外圆等多道工序,颇受人们的欢迎。但该机床也有一点美中不足之处,即当使用转塔刀架工作时,特别是进行钻孔和扩孔,在刀具刚刚穿透工件的一瞬间,由于转塔刀架工作负荷骤减,在压力油的作用下,整个转塔刀架产生冲击。冲击对产品质量大有影响,经常把刀具刃口折断,增加刀具的损耗。另外,该机床的床鞍在快退复位时,由于惯性作用,也会产生明显的冲击现象,给机床的精度产生一定的影响。为了解决这个冲击问题,我们对转塔刀架纵向工作的液压油路进行分析,认为要消除上述情况下的冲击,应该在转塔刀架进给油缸的回油路中分别增加两
CB3463-1 semi-automatic turret lathe is a relatively high production efficiency equipment. It can complete the product drilling, reaming, digging the inner groove and turning, cylindrical and other processes, quite popular. However, the machine tool also has some drawbacks, that is, when working with the turret tool holder, especially for drilling and reaming, the tool just penetrated the workpiece for a moment, due to the turret turret workload drastic reduction in pressure Under the action of oil, the entire turret turret has an impact. Impact on product quality greatly affected, often cutting off the cutting edge, increase tool wear. In addition, the machine saddle in the reentry reset, due to inertia, it will have a significant impact on the accuracy of the machine have a certain impact. In order to solve this impact problem, we analyzed the longitudinal hydraulic oil path of the turret turret, and considered that in order to eliminate the impact in the above circumstances, we should increase the oil return path of the turret turret feeding cylinder by two
