Abstract
With the development of industrial production, a variety of needs-clamp technique. On the one hand, due to the welding process development of industrial production made high demands on the other hand, science and technology, in order to improve the development of welding technology has opened up new avenues. In order to meet the needs of China's modernization, believe clamp technique will be more rapid development, and play a more important role in the development of industrial production. Parts fork foundation dedicated fixture design process planning and process design. Fork portion of the outer surface of the main processing, the stepped surface and the bore. In general, to ensure the machining accuracy of the machining accuracy of the plane than to ensure easy. Therefore, the first principle to follow trough surface design. Process and clear the hole and the plane is divided into roughing and finishing stages of processing to ensure the accuracy of the hole. After the first series of supporting hole machining flat top position, except that each process subsequent arrangements for dealing with the process of the hole with the top surface and other machining operations mainly deal with the positioning holes and planes. The use of special fixtures, jigs, fixtures clamping, automatic folder more choices, reliable clamping mechanism is not self-locking. Therefore, high production efficiency. For high-volume production lines. Able to meet the design requirements.
