Description

Technical Field

[0001] The present invention belongs to the technical field of welding equipment, and particularly relates to a welding fixture for a front windshield reinforcement welding assembly. Background Art

[0002] The automotive heater plenum panel assembly is mainly used for installing the wiper motor, supporting the front windshield, collecting the rainwater on the front windshield, and discharging the rainwater from both sides through the water trough. At the same time, the heater plenum panel is connected to the side A-pillar, the engine compartment side beam, and the middle reinforcement cross beam of the front wall panel to form a closed loop structure, enhancing the body strength and torsional stiffness, improving the local mode of the body, ensuring that the relevant performance indicators of the body meet the standards, and reducing problems such as abnormal noise, resonance, and fatigue durability in the later stage of the body.

[0003] A front windshield reinforcement 1 is welded on the heater plenum panel. The front windshield reinforcement 1 provides an installation surface for the front windshield glass. At the same time, the overall structure is in a cantilever form. When a pedestrian's head hits this area, the front windshield reinforcement 1 is crushed and deformed, reducing the impact and harm to the pedestrian's head. As Figures 1-3 shown, a water retaining platform support 2 is added at the water retaining platform of the front windshield reinforcement 1. The water retaining platform support 2 is welded to the front windshield reinforcement 1 and the plenum panel respectively. The water retaining platform support 2 is used to increase the local stiffness at the water retaining platform, avoiding the deformation or abnormal noise of the water retaining platform of the front windshield reinforcement 1 caused by the impact of rainwater, etc. Usually, the water retaining platform support 2 is first welded to the front windshield reinforcement 1, then the front windshield reinforcement 1 and the plenum panel are combined for welding, and the water retaining platform support 2 is welded to the plenum panel.
