Description

Technical Field

[0001] The utility model relates to a welding tool for automobile parts, in particular to a robot welding fixture structure for an automobile headlight crossbeam. Background Art

[0002] The car headlight beam is an important part of the car body in white. It mainly bears the left and right headlights and supports the weight of the front hood. According to the current installation and fixing method of the headlights, most cars use direct welding of the body frame, but the overall structural rigidity of the existing headlight beam is poor and cannot protect the lamp body structure well.

[0003] The automobile headlight crossbeam assembly is composed of a crossbeam body and a buffer block bracket. The crossbeam body and the buffer block bracket are welded. When welding the crossbeam body and the buffer block bracket, a welding fixture is required to clamp and fix the crossbeam body and the buffer block bracket. The existing welding fixture is as follows: Application No.: CN201820276252.0, a welding fixture for an automobile headlight crossbeam assembly, including a base, a first clamping device arranged on the base and used to clamp the crossbeam body, a second clamping device and a third clamping device, a first positioning device arranged on the first clamping device and used to position the crossbeam body, a second positioning device arranged on the third clamping device and used to position the crossbeam body, a fourth clamping device arranged on the third clamping device and used to clamp the buffer block bracket, and a third positioning device for positioning the buffer block bracket. This structure is complex, inconvenient to operate, and cannot achieve accurate positioning of the crossbeam body. During the welding process, the crossbeam body will deviate, resulting in the size of the assembly exceeding the tolerance, affecting the quality of the product after welding, and the production efficiency is low. The shape and position relationship between the automobile headlight beam assemblies will produce large deviations, leading to product consistency problems, and even product behavior tolerances will not meet design requirements, resulting in product scrapping. It is not suitable for robot welding assembly processing. Utility Model Content
