Rapid Modeling System For Astigmatism Veins Of Motor Lamps

With the continuous development and advancement of motor's manufacturing technology, the technology of motor lamps, whose main function is lighting and signal, keeps on updating all the time. Usually a motor lamp is made up of a bulb, a reflector and a lamp lens, out of which there are hundreds of astigmatism veins on the reflector and lamp lens. These astigmatism veins are used to coordinate the brightness, distribution and the scope of the light from the lamps, which determines the functions of use and safety directly.The units of astigmatism veins are characterized as small size, similar structure, large amount, high precision and so on. While modeling by hand, they are made one by one, resulting in huge amount of repeated work and low efficiency. This text will introduce the rapid modeling system for astigmatism veins of motor lamps in details. It is based on the platform of large 3D CAD software UG NX. Meanwhile it makes use of secondary exploit language Open GRIP, which is quite easy and interactive. This system is of strong utility, easy operability and good stability.The rapid modeling system for astigmatism veins of motor lamps is made up of internal function and external function. Internal function is made up of several function parts independently, which can realize ordinary astigmatism veins, such as yuyan astigmatism veins, pyramid astigmatism veins, three-corner astigmatism veins and so on. External part includes setup program, encryption program, deciphering program and data transfer program, those programs enhance the operability, stability and safety of the system.This passage will introduce every program in details including the theoretic base, the program process and technology difficulty. At the same time, rationality of each program was put to the proof through experiments.
