由于我们应用的B208 J型刨床,没有自动抬刀装置和机构,刀头很容易碰掉,人工抬刀劳动强度大,且又不安全,生产效率也低。后来,经过改进,增加了几个电气元件,便实现了自动抬刀。改进情况如刀架结构图(图1)所示。在刀架座板上铣或刨出一个宽20毫米,深22毫米的长方形环形槽,将一吸力线圈嵌入槽中,外包绝缘布,并用铜板压实,再用四只螺钉将铜板固定,并接出线圈的两个引出线 Because we used the B208J planer, does not automatically lift the knife device and body, the head is easy to knock off, manual lifting knife labor-intensive, and not safe, low productivity. Later, after improvement, an increase of several electrical components, it will automatically lift the knife. Improvements such as the tool holder structure shown in Figure 1. Milling or planing out a rectangular annular groove 20 mm wide and 22 mm deep on the turret base plate, inserting a suction coil into the groove, covering the insulating cloth, compaction with copper plate, fixing the copper plate with four screws Take out the two leads of the coil
