With the popularization and application of various welding processes in China, the automobile welding fixture and fixture have also been widely used in the manufacture and production of automobile equipment. The welding fixture can accurately locate and clamp the welding pieces, facilitate the assembly and welding of the welding parts, and ensure the requirements of the structure precision of the welding parts. . What are the functions of automotive welding jig in manufacturing?
1.guarantee the quality of welding
The common welding quality problems in welding production are welding stress and welding deformation. The main reason for welding distortion and welding stress is the uneven heating and cooling of weldments during welding. If the fixture is not used, it is not only difficult to ensure the precise relative position of the parts, but in the process of welding, it is difficult to control the deformation and stress produced by the welding parts, especially the complex structure. The sample will affect the general assembly work behind it.
2. Reduce labor intensity and ensure safe production
With the wide application of welding technology in the automobile manufacturing industry, various welding fixtures are constantly being designed and innovating. In the production and manufacture of the workshop, if the welding fixture is used to match the structure of the welded parts, it can make the workpiece positioning fast and easy to install, and use the equipment instead of manual control to control the manufacturing tolerances, thus reducing the heavy manual labor when the welding parts are assembled and tightened and saving a lot of labor. It reduces the labor intensity of the operating workers.
3.improve labor productivity and reduce production cost
All welding structure parts generally include: preparation before welding, assembly, welding, cleaning and inspection. In the general manufacturing production, the welding workload after the welding structure parts positioning and clamping is only a small part of the manufacturing production, the amount of labor before and after welding is far greater than the welding process itself, which accounts for the largest proportion of the whole production time.
4.ensure the assembly precision
The auto welding fixture is a kind of process device designed to meet the assembly of welding parts. The main function is to ensure the relative tolerance and shape tolerance of the component welding components before and after the assembly and welding, and to ensure the assembly precision after the final assembly.
The role of automobile welding fixture in manufacturing and manufacturing is shared today. As welding structures are widely used in various fields, welding fixture and fixture have been widely used in manufacturing. In the manufacture of welding equipment, welding is the key to the assembly of parts and the assembly of the whole equipment. It is necessary to use the fixture to complete the quality of the assembly and welding of the products. Therefore, the welding fixture is the most important part of the assembly of the welding parts.
