The Design Of Scroll Compressor Assembly Management System Based On.NET

Computer-aided selective assembly is a new method to improve the accuracy of mechanical product assembly, which uses computer can quickly complete the characteristics of a large number of complex calculations, it uses effective algorithms to find the reasonable matching choices about the deviation of the various components of the assembly dimension chain ring to achieve the purpose of improving assembly accuracy.IDEF (ICAM Definition Languages) was invented by the U.S. Air Force in the1970s, first used to describe the operation of the internal set of modeling methods. After constantly refined and improved, its use becomes widespread, now can be applied to software development in general.The article based on a particular model of a company scroll compressor as the object of study, through the following aspects of the study, eventually establish a complete assembly management system.1、First, analyse the characteristics of assembly of moving and stationary plate, mainly divide into two aspects of the radial clearance and axial clearance, then combine the characteristics to establish size chain optional model and matching algorithm model. The dimension chain matching model is divided into radial dimension chain model and the axial dimension chain model, and the matching algorithm model is based on the number of optional parts are divided into batch matching model and packet-fast matching model.2、Secondly, based on IDEF modeling methods, with IEDFO and IDEF1X two methods to establish the functional model and information model of the system, and to design the database table based on the IDEF1X method, thereby completing the major part of the design of the system.3、Finally, to design the system auxiliary function module and to demonstrates the peace of simulation matching. The entire system using Microsoft Visual Studio2005as the development tools, using Microsoft SQL Server2005as the database management system of the server-side, and access to the database using ADO.NET technology.Through the above aspects of the research, from modeling to the final completion of the operation of the entire system, transform the traditional manual matching which needs a lot of manpower and time-consuming into a fast, efficient computer-aided optional, and can be used to guide field assembly, improving production efficiency greatly.
