Key Words: Welding assembly Location 1. Introduction Assembly and welding fixture in the automotive body assembly and welding production line of critical process equipment related to manufacturing quality of the car. Assembly and welding fixtures in addition to the completion of this process the parts assembly, positioning, the also served as a test and calibration procedures on the Road. welding quality of the task, so its design and manufacture of the welding process affects the level of automobile production capacity and product quality. Automotive style vary, welding fixture shape and thus vary widely, but in the design, manufacture, adjustments have in common, you can learn from each other. 2. the structural design of welding fixture Fixture structural design, to ensure that the folder has a good convenience of operation, clamping positioning reliability. Fixture manufacturers also adjusted to ensure easy integration of various parts of the structure surface should allow sufficient room for adjustment to ensure the three-dimensional adjustable. Ensuring the accuracy of the welding quality and welding under the premise of the structure of fixture should be as simple as possible. Fixture design is usually the general use of welded structures, the basic component is divided into three parts, namely base, support the positioning part, clamping parts, for each specific fixture positioning support base and some of the general use of 10 to 20 mm thick steel plate welded structure A3.Clamping part of the normal 10 mm with a thickness of about 45 combination of welded steel plate. Pneumatic and manual clamping part of the two, according to the size
