The Function of Automobile Welding Fixture in Manufacturing
With the promotion and application of various welding production processes around the world, automobile welding jigs and fixtures have also been widely used in automobile equipment manufacturing. Automobile welding jigs and fixtures can accurately position and reliably clamp welding workpieces, facilitate assembly and welding of weldments, and ensure the process equipment required for structural accuracy of weldments. So what is the role of automobile welding fixture in manufacturing?
1. Ensure welding quality
The common welding quality problems in welding production are welding stress and welding deformation. Uneven local heating and cooling of weldments during welding is the main reason for welding deformation and welding stress. During assembly and tack welding, if the tooling fixture is not used, it is not only difficult to ensure the accurate relative position of each part, but also difficult to control the deformation and stress generated by the welding parts during the welding process, especially for complex structures, whose deformation can sometimes reach the extent that can not be eliminated, and even cause the product to be scrapped in serious cases, which will affect the subsequent general assembly work.
2. Reduce labor intensity and ensure safe production
With the extensive application of welding technology in the automobile manufacturing industry, all kinds of welding fixtures are constantly being designed and innovated. If the welding fixture matched with the structure of the weldment can be used in the workshop production and manufacturing, the workpiece can be positioned quickly and clamped easily. Tooling equipment is used instead of labor to control the manufacturing tolerance, which reduces the heavy manual labor during the assembly, positioning and tightening of the weldment, saves a lot of labor, and reduces the labor intensity of the operators.
3. Improve labor productivity and reduce production costs
The production process of all welded structural parts generally includes: preparation before welding, assembly, welding, cleaning and inspection. In general manufacturing and production, the welding workload after positioning and clamping of welded structural parts is only a small part of manufacturing and production. The labor volume of various auxiliary processes before and after welding is far greater than the welding process itself, accounting for the largest proportion of the entire production time.
4. Ensure assembly accuracy
The automobile welding fixture itself is a process device designed to meet the assembly of welding parts. Its main function is to ensure that the assembly welding components can reach the designed relative position tolerance and form and position tolerance before and after assembly and welding, and ensure the assembly accuracy after final assembly.
