Description

Technical Field

[0001] The utility model belongs to the technical field of welding fixtures, and in particular relates to a robot welding fixture. Background Art

[0002] Welding is a necessary process in modern machinery manufacturing and is widely used in vehicle manufacturing. Different from the current traditional spot welding process, brazing can achieve molecular bonding between two steel plates. In layman's terms, the hardness of the welded steel plate is equivalent to that of a whole steel plate, thereby increasing the strength of the vehicle body by 30% and greatly improving the bonding accuracy of the vehicle body.

[0003] For example, the Chinese patent CN213916797U proposes a robot welding fixture, which includes a welding arm; a workbench is provided on one side of the welding arm; both ends of the workbench are connected to the flip seat, and a fixture base is provided on the surface of the workbench; a fixed support platform is provided on the surface of the fixture base; a first cylinder mounting block is provided on the fixed support platform; an angle adjustment seat is provided on the first cylinder mounting block; the first cylinder is connected to the angle adjustment seat; the first cylinder is hinged with the swing arm; and one end of the swing arm is connected to the first cylinder mounting block. In the utility model, a fixed support platform is provided on the workbench, and the fixed support platform and the first matching block and the second matching block on the lower side jointly form a clamping space. When welding a relatively slender workpiece, it can ensure that the parts are in an upright clamping state, rather than being placed flat on the workbench, and the contact area between the clamping arm and the workpiece is small, while the clamping is stable, the normal operation of the welding arm is guaranteed. However, in the actual application process, the scheme cannot directly weld different surfaces of the object, thereby affecting the welding efficiency of the object. To solve the above problems, we propose a robot welding fixture. Utility Model Content
