Description

Technical Field

[0001] The invention relates to the technical field of fuel filler pipe laser welding, in particular to a fuel filler pipe laser welding device equipped with a clamping structure. Background Art

[0002] In many fields such as automobile manufacturing and aerospace, the welding quality of the fuel pipe is crucial. Traditional fuel pipe welding methods, such as arc welding and resistance welding, have many defects. For example, arc welding is prone to large thermal deformation, which makes it difficult to ensure the dimensional accuracy of the fuel pipe, affecting subsequent installation and use. Resistance welding may result in loose welding. During long-term use, cracking and leakage are prone to occur at the weld, which brings serious safety hazards. With the development of laser technology, laser welding is gradually applied to the welding of fuel pipes. However, during the laser welding process, due to the shape and structural characteristics of the fuel pipe, if there is a lack of effective clamping and positioning, welding deviations are likely to occur, and high-precision welding requirements cannot be met.

[0003] The welding equipment currently used usually rotates the workpiece itself. During the rotation process, the two sets of workpieces butted together are prone to relative shaking, which causes deviations in the interface and affects the quality of the interface welding.

The first bracket and the second bracket can be driven to move on the adjustment slideway by the electronic slider, and the first bracket and the second bracket are driven to move the first clamping mechanism and the second clamping mechanism respectively, so that the fuel pipe and the bell mouth can be butt-jointed together, and then the fuel pipe and the bell mouth can be welded together by the welding device, so that the clamping position of the first clamping mechanism can be freely adjusted.

Then, the driving gear is driven to rotate by the driving mechanism, and the driving gear drives the arc rack to rotate. The arc rack drives the arc telescopic rod and the welding gun to rotate. The connection between the fuel pipe and the bell mouth can be welded by the rotation of the welding gun. The welding gun is directly rotated during welding to avoid relative shaking between the fuel pipe and the bell mouth during rotation, which may cause deviation at the interface. Since the arc telescopic rod is also provided, when the gear rack structure moves to the end, the welding gun can be driven to continue to move by the extension of the arc telescopic rod, so that the welding gun can complete a complete circle of welding to avoid secondary welding.
