切向喷咀如图1所示,为保证偏心距e±0.1、孔距L±0.1和孔径φdH8尺寸,原来每一种规格的零件都要设计和制造一套专用钻模,但因品种多、周期短,不但满足不了科研生产的要求,而且产品的成本也高。为此设计制造了图2所示的通用钻模。经过几年的实际使用,效果很好。一、结构原理该钻模由基体1、定向销2、压紧螺钉3、可移动钻模板4、可换钻套5、紧固螺栓6、19和23、手柄7和15、分度盘8、转轴9、可换定位轴10、摩擦
Tangential nozzle shown in Figure 1, in order to ensure the eccentricity e ± 0.1, the pitch L ± 0.1 and the aperture φdH8 size, the original design and manufacture of a set of specifications for each part of a dedicated drilling die, but more varieties , Short cycle, not only can not meet the requirements of scientific research and production, but also the high cost of the product. Designed and manufactured for this purpose shown in Figure 2 Universal Drill. After several years of actual use, the effect is very good. First, the structure and principle of the drill from the base body 1, the orientation pin 2, the compression screw 3, the movable drill template 4, drill sleeve 5 can be replaced, fastening bolts 6,19 and 23, the handle 7 and 15, indexing plate 8 , Shaft 9, changeable positioning shaft 10, friction
