在没有先进设备的情况下,加工大量的网孔是十分困难的。我厂尘笼纺纱机上的尘笼具有30672个φ1mm小孔,小孔呈正三角形分布(见图1中,O_1O_2O_3所示),孔距为1.36mm,此零件的小孔加工成为工艺难题。为了提高生产效率我们设计了钻孔专用设备。经过生产实践验证,达到了图纸要求,获得了较好的效益,现介绍如下: 一、钻削工艺方案的确定根据工件网孔分布可有两种钻孔方案选择。一种是沿工件轴向对每行142孔先进行钻削,当一行孔全
In the absence of advanced equipment, processing a large number of mesh is very difficult. The dust cage on the dust cage spinning machine in our factory has 30,662 φ1mm small holes with an equilateral triangle distribution (see O_1O_2O_3 in Fig. 1). The hole pitch is 1.36mm. The hole machining of this part becomes a process problem. In order to improve production efficiency we designed a special drilling equipment. After the production practice verification, has reached the drawing request, obtains the better benefit, now introduced as follows: First, the drilling craft plan confirmation According to the work piece mesh distribution may have two kind of drilling plan choice. One is along the workpiece axis 142 holes per hole for the first drilling, when a row of holes full
