在常用的普通车床拖板上装一个内旋风切削头加工内外螺纹的方法,由于结构的原因,调整主轴倾角和刀头回转中心高必须同时进行,很不方便。为了克服上述缺点,在原旋风头底座和主轴壳体之间加一块垫板、两只导向销轴、两只短螺柱,并将原有的相关零件作相应的改动(如图1所示) 从而使主轴倾角和刀头回转中心高可以分别调整,其步骤为(见图1、2):松开长螺柱6和短螺柱7,主轴
In the common lathe carriage mounted on a whirlwind cutter head machining internal and external thread method, due to structural reasons, adjust the spindle inclination and the head center of rotation must be carried out at the same time, very inconvenient. In order to overcome the above shortcomings, a pad, two guide pins and two short studs are added between the base of the original cyclone head and the spindle housing, and the corresponding related parts are modified accordingly (as shown in FIG. 1) So that the main shaft tilt and head rotation center height can be adjusted separately, the steps (see Figure 1,2): Loosen the long stud 6 and short stud 7, the spindle
