Abstract
Flange is a common connecting element in industrial products.Its typical processing technology includes:analysis of part drawing,design of blank drawing,preparation of machining process,preparation of NC machining process,selection of NC machining tools and drawing of NC machining feed route,etc.For those difficult to process in procedure 8 φ 6 mm inclined hole,a set of special fixture for drilling machine is designed,in which the drilling template is designed as a reversible style,and the drilling sleeve is designed as a quick change special drilling sleeve.The fixture adopts the positioning scheme of one side and two pins,which limits the six degrees of freedom of the workpiece and achieves complete positioning.Finally,the positioning error of the fixture is calculated.After checking,it is determined that the positioning error of the fixture is controlled within the machining accuracy requirements of the drawing and meets the machining requirements.关键词
