我厂工人李定波等同志制造成功一台木工专用銑榫机,效果显著,現简单介紹其构造,供参考(見附图)。动力由电动机1通过变速齿輪2带动齿輪3、光杆4及凸輪5,推动刀座13向前作横向运动,再借彈簧6拉回原位。刀座可从0°旋轉到360°,根据加工需要任意选取。榫的大小和深淺亦可自由調节。齿輪3又通过鏈条7拉动撑牙8,后者为間歇运动(在一周中轉动半周,停止半周),通过絲杠9传至刀 Our factory worker Li Dingbo and other comrades successfully manufactured a woodworking tenoner, the effect is remarkable. Now, we briefly introduce its structure for reference (see the attached figure). Power from the motor 1 through the transmission gear 2 driven gear 3, polished rod 4 and the cam 5, pushing the knife 13 forward for lateral movement, and then by spring 6 pulled back to its original position. Knife seat rotation from 0 ° to 360 °, according to the processing needs of any choice. Tenon size and depth can also be adjusted freely. The gear 3 in turn pulls the spur 8 through a chain 7, which is intermittent (half a revolution in a week, half a week in halt), transmitted to a knife
