With the popularity of the automobile, automobile manufacturing in demand for jig is also rising. One car welding jig because of their excellent performance advantages of having obtained the car manufacturers of all ages. Simply put, car body welding welding jig is to ensure the quality of the important factors, the role is to ensure that the relative position between the dimensional accuracy after welding All welding stampings. Here Kunshan Xindakang professionals automobile welding jig design on which to meet the requirements.
1, standardized welding fixture, jig modular element is to achieve a combination of foundation. With a modular design series, standardized clamp member, quickly assembled into a variety of fixtures, it has become a fixture technology development basis points. Saving labor, time, materials, energy saving, innovation is reflected in a variety of advanced systems among jig. Modular design and assembly fixture design basis.
2, the structural characteristics of the welding jig: body welding fixture bulky, complex structure, for ease of manufacture, assembly, testing and maintenance, must break down the structure of the fixture, otherwise, can not be measured. Each fixture has its own reference coordinates, according to the reference of each member fit together. Automobile welding jig is generally divided into three parts: base plate, the left and right around the circumference. So there are three mounting reference on their respective floors are processing oil fiducials and coordinate lines, each smaller units according to their benchmarks assembly, testing. Finally, the three parts are combined into a complete welding jig.
3, the control requirements of the welding fixture: welding workpieces usually between two or three workpiece, a plurality of workpieces each sub-assembly or assembly fixtures, so more than normal clamping point, is a resistance welding efficient welding process, in order to reduce the auxiliary time stevedores, clamping devices and should be fast and efficient multi-point linkage. Clamping force is mainly used to maintain the relative position of the workpiece assembly, against the elastic deformation of the workpiece, positioning it with the support or the conductive electrode paste, according to the manual operation mode can be divided intensify, intensify pneumatic, hydraulic intensify the like. Intensify head generally consists of steel or nylon material to suit different workpiece requirements.
4, welding jig positioning requirements: welding jig to be performed separately for each welding workpiece positioning, and so as not to interfere with each other, the general use of the workpiece positioning hole and the surface, there are a lot more complex shape of the workpiece, which in a very large extent determines its positioning element shape rather special, designed to take full advantage of the positioning element when the workpiece assembly interdependent nature of the relationship as a positioning support.
For automotive welding fixture design to meet the requirements of today which share here, in addition to the automobile welding jig design features, to ensure the quality of the welding of the body must first ensure that the quality of automotive welding jig, affecting the quality of automobile welding jig factors include manufacture and installation commissioning testing points.
