在生产630t水压机的过程中,我们用T611镗床加工了11种不同类型的阀体。这些阀体上有M10～M155×3的各种螺纹孔,其中大的螺纹孔只能借助螺纹加工的工装才能完成。一、工作原理及工装结构工作原理是利用挂轮改变机床主轴轴向进给的传动比来控制螺距t。挂轮结构如图1所示。用两个螺栓2将挂轮架1固定在镗床主轴箱尾部,挂轮轴套12与B组齿
In the process of producing 630t hydraulic press, we processed 11 different types of valve bodies with T611 boring machine. These bodies have all kinds of M10 ~ M155 × 3 threaded holes, of which large threaded holes can only be completed with the help of thread processing tooling. First, the working principle and tooling structure The working principle is to use the gear change to feed the spindle axial feedstock to control the pitch t. Hanging wheel structure shown in Figure 1. With two bolts 2 will be linked to a fixed wheel frame boring headstock box, the hanging wheel shaft sleeve 12 and B group of teeth
