Abstract

The invention provides a welding bracket. The welding bracket comprises three rectangular base surfaces and seven welding surfaces, wherein the three rectangular base surfaces comprise a first rectangular base surface (1), a second rectangular base surface (2) and a third rectangular base surface (3); the seven welding surfaces comprise a first welding surface (4), a second welding surface (5), a third welding surface (6), a fourth welding surface (7), a fifth welding surface (8), a sixth welding surface (9) and a seventh welding surface (10); and the different welding surfaces are connected with the different base surfaces. The welding surfaces are used for welding the welding bracket to a rear stringer assembly structure, a sill inner plate rear section assembly structure and a rear floor front extension plate assembly structure of a vehicle body, among which gaps exist, so that the gaps among the three assembly structures are filled through the welding bracket provided by the invention. The welding bracket provided by the invention solves the problem that a special-shaped beam is difficult to produce when the special-shaped beam is adopted to fill the gaps in the prior art.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a welding bracket. Background technique [0002] As the market demand for automobiles continues to diversify, the subdivision of automobile products continues to increase, and the number of vehicle models gradually increases. However, usually a variety of different models of automobiles are produced on the same production line. Therefore, some models produced on the same production line are affected by the structure of the suspension system, making the structure of the rear longitudinal beam assembly and the rear section assembly of the inner panel of the door sill The structure cannot be directly welded, resulting in gaps between the rear longitudinal beam assembly structure, the rear section assembly structure of the door sill inner panel and the front extension panel assembly structure of the rear floor. [0003] In the prior art, the rear longitudinal beam is generally pro...
