Problems solved by technology

If the strength of the reinforcement plate is not enough or the shape hole does not fit the outer door panel, it will affect the appearance of the whole vehicle and the smooth lifting of the door glass
[0003] At present, the welding of many automobile door lower hinge reinforcement plate assemblies has problems such as welding quality defects and dimensional instability due to unstable positioning. When the door lower hinge reinforcement plate assembly is assembled, the door lower hinge will be strengthened. The plate assembly cannot be assembled smoothly on the door
The main technical problems of existing welding fixtures are: low welding efficiency, low positioning accuracy, poor error proofing and other defects. Therefore, corresponding special welding positioning fixtures must be equipped during the welding process, which can further improve welding efficiency and ensure its welding stability
Therefore, if the fixture is used for welding the door lower hinge reinforcement plate and the parts to be welded, the improvement of the positioning accuracy of the parts to be welded is limited.

Embodiment 1

[0035] Such as Figure 1~5 As shown, a welding jig for robot welding of automobile door lower hinge reinforcement plate assembly, including a jig bottom plate 1 and a coaxial positioning mechanism installed on the jig bottom plate 1, an anti-rotation mechanism for parts to be welded, and a door lower hinge reinforcement Plate anti-rotation mechanism and quick clamp 2. When welding accessories, the coaxial positioning mechanism will coaxially position the accessories to be welded and the reinforcement plate of the lower hinge of the door, and the anti-rotation mechanism of the accessories to be welded and the anti-rotation mechanism of the reinforcement plate of the lower hinge of the door are treated separately Welding fittings and the lower hinge reinforcement plate of the car door are limited, and the quick press pliers 2 press the fittings to be welded on the lower hinge reinforcement plate of the car door.

[0036] A plurality of circular holes 18 and waist holes 19 are ar...

Embodiment 2

[0049] The coaxial positioning mechanism, the anti-rotation mechanism of the parts to be welded, the anti-rotation mechanism of the lower hinge reinforcement plate of the car door and the quick press pliers 2 are provided with three groups, which are arranged in parallel on the left and right, and can simultaneously adjust the lower hinge reinforcement plate 16 of the three groups of doors. Welding fittings 17 are positioned and assembled.

[0050] The positions of the anti-rotation mechanism of the parts to be welded and the anti-rotation mechanism of the door lower hinge reinforcement plate can also be adjusted according to the shape of the door lower hinge reinforcement plate 16 and the accessories to be welded 17 of different models, as well as the welding position and the position of the positioning hole. For example, it is arranged on the left and right sides of the jig bottom plate 1 .

[0051] All the other are identical with embodiment 1.

Abstract

The invention relates to a welding jig for a robot to weld automobile door lower hinge reinforcing plate assemblies. The welding jig is used for coaxially positioning automobile door lower hinge reinforcing plates and accessories to be welded of the automobile door lower hinge reinforcing plate assemblies, so that the accessories to be welded are welded on the automobile door lower hinge reinforcing plates. The welding jig comprises a jig bottom plate, coaxial positioning mechanisms, rotation preventing mechanisms for the accessories to be welded, rotation preventing mechanisms for the automobile door lower hinge reinforcing plates and rapid press pliers. The coaxial positioning mechanisms, the rotation preventing mechanisms for the accessories to be welded, the rotation preventing mechanisms for the automobile door lower hinge reinforcing plates and the rapid press pliers are arranged on the jig bottom plate. Compared with the prior art, the welding jig has the advantages of being easy to operate, convenient to overhaul, dismount and mount, good in error detection, good in welding quality stability, high in production efficiency and the like.

Description

technical field [0001] The invention belongs to the technical field of automobile manufacturing and processing, and relates to a welding jig, in particular to a welding jig used for welding a reinforcement plate assembly of a lower hinge of an automobile door by a robot. Background technique [0002] The door hinge reinforcement plate connects the outer panel of the rear door of the car and other parts together, and plays a role in strengthening the curing of the stamped parts. If the strength of the reinforcing plate is not enough or the shape hole does not fit the outer door panel, it will affect the appearance of the whole vehicle and the smooth lifting of the door glass. [0003] At present, the welding of many automobile door lower hinge reinforcement plate assemblies has problems such as welding quality defects and dimensional instability due to unstable positioning. When the door lower hinge reinforcement plate assembly is assembled, the door lower hinge will be stren...
