一、空间斜孔的基本情况在组合夹具中,钻模占50％以上,而其中比较难装的夹具,多数是加工有空间角度斜孔的钻模。例如在油泵体、分配器上钻油孔;在法兰盖、阀体上钻气孔;在不重磨刀体上钻螺孔;在机体、连接盘和各种形状支架、摇臂上钻斜孔等钻模。这些具有两个方向的空间斜孔计算比较复杂,目前解决的办法有如下几种: (1)主体图解法:按几何、三角立体关系进行图解; (2)球面三角计算法:按球面公式图解和计算; (3)几何投影换算法,按35个公式进行换算;
First, the basic situation of space slant hole In the combination of fixtures, drilling accounted for more than 50%, of which the more difficult to install the fixture, the majority of oblique angle hole machining is a drilling angle of the hole. For example, in the oil pump body, distributor oil hole drilling; in the flange cover, the valve body drilling holes; drill in the non-regrind body screw holes; body, the connection plate and various shapes of support, Hole and other drilling. These two-directional space oblique hole calculation is more complex, the current solutions are as follows: (1) the main graphic method: according to geometric, triangular stereo relationship diagram; (2) spherical trigonometry: spherical formula And calculation; (3) geometric projection conversion algorithm, according to 35 formulas conversion;
