Description

Technical Field

[0001] The utility model relates to the technical field of laser welding, in particular to a bevel flange structure for improving the quality of laser welding. Background Art

[0002] Laser welding technology uses high-energy laser pulses to locally heat the material in a small area. The energy of laser radiation diffuses into the interior of the material through heat conduction, melting the material to form a specific molten pool. It is mainly used for welding thin-walled materials and precision parts. It has fast welding speed, smooth and beautiful welds and high quality.

[0003] Different welding positions have different requirements for laser welding. When two parts are welded vertically, the laser beam is generally used to weld along the contact line of the end face to form a vertical seam perpendicular to the surface of the workpiece. The welding track is formed by the contact surface between the bottom of the part and the main board. In the structure of vertical contact laser welding of parts, when the position of the parts and the welding angle change slightly during the welding process, the welding depth will change, which affects the stability of the welding. This type of welding requires higher laser power and precise positioning control, and has high requirements for laser equipment; high laser power and precise alignment control mean high equipment costs.

[0016] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0017] Example

[0018] like Figure 1 As shown, a bevel flange structure for improving laser welding quality includes a first welding component 1, the end surface of the first welding component 1 is welded to a second welding component 2, and the end surface of the first welding component 1 and the bottom surface of the second welding component 2 are provided with a bevel welding structure 3.

[0019] In this embodiment, a threaded hole 4 is provided in the middle of the second welding component 2, and the threaded hole 4 is used for fixing and locking connection with other parts or structures.

[0020] The bevel welding structure 3 is composed of a plurality of symmetrically arranged bevel blocks 5 , and the number of the plurality of bevel blocks 5 can be adjusted according to the second welding components 2 of different sizes.

[0021] The bottom surfaces of the plurality of inclined blocks 5 are connected to the end surface of the first welding component 1 , and the end surfaces thereof are in contact with the bottom surface of the second welding component 2 .

[0022] The multiple symmetrically arranged inclined blocks 5 serve as laser welding surfaces, and the thickness of the multiple inclined blocks 5 can be adjusted according to the power of the laser equipment and the laser travel speed.

[0023] The laser welding trajectory is concentrated on the bevel, which increases the welding area. The laser welding trajectory is not limited to the contact line, which reduces the requirements for equipment alignment control. The increase in the welding area allows the parts to be closely combined with each other and is easier to operate. At the same time, the bevel structure can better help limit the parts and facilitate laser welding. The increase in the laser welding area reduces the impact of external factors during the welding process and improves the stability of laser welding. The thickness of the bevel structure needs to be adjusted according to the power of the laser equipment and the laser travel speed to meet the welding depth requirements. The bevel angle is designed to facilitate laser travel.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
