This time the door of welding jig design is no exception. Welding jig design production preparation work of the important content, is also a major design welding production process one of the contents. For the car, motorcycle and aircraft and other manufacturing industries, can it is no exaggeration to say, no welding jig is no products. Through the process design of equipment needed to put forward types, structure sketches and briefly explain, based on the structure and complete detailed parts design and all designs. Tooling design on production efficiency and the quality of the manufacturing cost, product quality and production safety, so direct shadow ring, welding fixtures must consider when the practicability and economy, reliability and artistic quality, etc. The fixture design and the manufacture process and the prevalent topic dimension chain. In the parts assembled into the process of assembling body parts, it is about size combination and accumulation. Because parts size manufacturing error, so there will be also assembling the comprehensive and accumulation error. After the total error accumulation form will affect the machine for the work performance and quality. This creates a part size error and the integrated error the interrelation between. Because this reasonably determine the parts dimension, form and position tolerances is particularly important. Key words:car,structural design，car door，fixture design II
