Study on Development Technology of Production Drawing Gallery of Belt Conveyer Middle Frame Based on AutoLISP

The DTⅡ( K) type of belt conveyer is a general series of product which should be designed by series components. Based on different terrain and transportation distance,the type of the belt conveyer middle frame which has standard length or opposite can be divided into three types of straight,convex arc and concave arc. Auto LISP is used to make Auto CAD secondary development to generate the production drawings for the middle frame. According to the type and length of the frame,different dialog boxes have been programmed. After the belt width is determined,the corresponding parameters are input into the dialog boxes to generate production drawings for the middle frame with different type and length. Thus,the parametric design for the production drawing gallery of middle frame is achieved.
