Abstract


Three type parallel indexing cam mechanism is a flat cam intermittent indexing mechanism, owing to its sports performance, high precision indexing is widely used in cutting machines, printing presses and other automatic machines and automatic lines. This article from the CAD / CAM integration technology point of a more comprehensive study three Parallel Indexing Cam Mechanism static design, dynamic analysis, 3D model creation and the cam processing problems, and use of object-oriented visual development tools VC 6.0, Pro / Engineer of the secondary development tool Pro / Toolkit, Access databases developed a three-in parallel indexing cam mechanism dedicated CAD / CAM software systems. Details are as follows: 1. Pair of three-in parallel indexing cam mechanism to study the formation of profile curve, introduces several common law follower motion characteristics, and using coordinate transformation method derived institutions and size parameters of the motion parameters of the calculation formula, the use of VC 6.0 Programming convex contour point coordinate data of the strike, while the bodies of several sports conditions for analysis and discussion. (2) to a division three nine roller-type parallel indexing cam, for example, the establishment of the three-in parallel indexing cam mechanism and kinetic model dynamic differential equations of the model, using matlab to solve the equation and draw a different law of motion, under different parameters displacement error response curve, acceleration response curve, the pros and cons of various laws of motion and the different parameters on the response of the system to analyze and compare, respectively. 3 introduces the Pro / Toolkit features, the use of Pro / Toolkit for secondary development of the specific process and add a menu, interactive user interface making, three-dimensional model based on a template parameter design and other technical discussion. 4 using object-oriented and modular design method, in the form of a dynamic link library, the use of VC 6.0, Pro / Toolkit, Access and other tools to develop a set of Pro / Engineer system under the three-type parallel indexing cam mechanism dedicated CAD / CAM system. In the CAD module development process, the main shaft of indexing plate and parametric design, convex contour design and solid modeling, kinematic simulation, automatic output-dimensional engineering drawings, parts library management sub-module; in the CAM module development process, the main research library milling tool development, process simulation and NC code for other sub-modules. Eventually, the system being developed for the three-type parallel indexing cam mechanism design and manufacturing to provide a fast and accurate software platform.
