A positioning welding tool for the nail planting cover plate assembly of the right front wheel cover of the automobile

Abstract

The invention discloses a positioning welding tool for the right front wheel cover of an automobile, which comprises a welding support platform and at least one set of support and clamping mechanisms arranged above the welding support platform along the length direction of the cover assembly. , each of the plurality of supporting and clamping mechanisms includes a fixed supporting mechanism and a movable clamping mechanism, the fixed supporting mechanism supports the cover plate assembly, the movable end of the movable clamping mechanism is located above the cover plate assembly, and each The movable end of the movable clamping mechanism of the group clamps or deviates from the cover panel assembly on the corresponding fixed support mechanism; the fixed support mechanism is supported on the inner surface of each fitting surface M of the cover panel assembly, and the The movable end of the movable clamping mechanism is correspondingly pressed on the outer surface of each fitting surface M, which can accurately locate and clamp the cover plate assembly and ensure high-quality nail-planting welding.

Description

technical field [0001] The invention belongs to the field of welding of automobile shell parts, in particular to a positioning welding tool for an automobile right front wheel cover stud-planting cover plate assembly. Background technique [0002] With the development of society and the progress of science and technology, all walks of life have ushered in rapid development. For example, the manufacturing industry, the manufacturing industry is the foundation of the equipment industry. It is necessary to manufacture parts with high precision and strong stability to ensure the stability and reliability of the entire equipment. ; But in the process of machining parts, the most used fixture is the fixture. In the automobile manufacturing industry, the welding process is essential. The automobile front wheel cover assembly is used for the gap between the front floor and the front tire. Parts, Surrounded by overlapping surfaces, the precision of the parts is higher, the shape requ...

[0003] as attached figure 1 As shown, it is the automobile front wheel cover assembly corresponding to the special welding tooling of the present invention. The point P in the figure is the welding place of each nail or the nut welding place. The figure contains several fitting surfaces M, wherein: M1 is the wheel speed The sensor installation surface is also the installation surface with the car body suspension; M2 is the bonding surface of the cover plate assembly and the car body suspension reinforcement plate assembly; M3 is the bonding surface of the cover plate assembly and the expansion tank; M4 is the cover plate assembly The bonding surface of the plate assembly and the ECU mounting bracket is required not to be deformed during welding, and the welding stability of each nail planting and the welding position of the nail planting must be ensured. The requirements for welding are very high. But at present, the welding method of the car factory is only to support and fix the cover plate assembly through a simple bracket. Lack of support, easily deformed during welding
