Description

Technical Field

[0001] The utility model relates to the technical field of laser welding, in particular to a wire feeding mechanism for laser welding. Background Technique

[0002] Laser welding is an efficient and precise welding method that uses a high-energy laser beam as a heat source to rapidly heat and melt the workpiece to achieve high-quality and high-strength welding. Automatically synchronously feeding the welding wire during laser welding is laser filler wire welding. Laser filler wire welding not only has the advantages of high energy, good welding quality, and small deformation of laser fusion welding, but also improves the gap margin during welding, increases the "bridging" ability of laser welding, and increases the flexibility of the welding process. It is a very promising welding method.

[0003] The prior art has the following deficiencies: In the prior art, in the "wire feeding mechanism for laser welding" with the application number 202322877184.7, "it includes a housing and a material tray. The material tray is placed inside the housing. A bearing plate is rotatably arranged on the housing through a driven rotating rod. A strip-shaped boss is fixedly arranged on the bearing plate. An installation plate is vertically deflectably arranged on the strip-shaped boss. Two groups of wire feeding wheels for feeding the welding wire are symmetrically arranged on the installation plate, and a corresponding number of driving motors for driving the wire feeding wheels to rotate are arranged. A deflection mechanism is arranged on the housing for laterally deflecting the bearing plate to adjust the wire feeding direction in the horizontal direction."

[0004] By setting the deflection mechanism, the above-mentioned device can conveniently adjust the wire feeding direction to meet the actual operation requirements and improve the adaptability of the wire feeding mechanism. However, the size of the conveying gap between the two groups of corresponding wire feeding wheels of the above-mentioned device is usually fixed and difficult to adjust. When feeding welding wires of different diameters, it is often necessary to replace wire feeding wheels of different diameters to adjust the conveying gap, which is rather troublesome. Moreover, the wire feeding wheels of the above-mentioned device are often worn during use. When the wire feeding wheels are worn to a certain extent, it will affect their conveying effect. Therefore, they need to be replaced. However, when the wire feeding wheels of the above-mentioned device are worn, the whole wire feeding wheels need to be replaced, which is likely to cause waste of resources.

[0039] Working principle and usage process of the utility model: The mounting plate 13 is installed at a suitable position through bolts so that the wire feeding port of the wire feeding mechanism corresponds to the position of the laser welding machine. The welding wire 14 to be conveyed is wound around the material tray 2.

One end of the welding wire 14 is passed through the conveying gap between the two groups of adjusting wheels 3 and the corresponding wire feeding wheels 4. The operation of the two groups of driving motors 702 is controlled through relevant control switches to make the adjusting wheel 3 closely adhere to the welding wire 14, and the adjustment of the conveying gap can be completed, which is relatively convenient. The rotating motor 6 drives the material tray 2 to rotate, and the welding wire 14 can be gradually conveyed through the conveying gap between the adjusting wheel 3 and the wire feeding wheel 4;

[0040] In the above process, due to the anti-slip limiting effect of the anti-slip member 9, the replacement member 8 will not rotate independently, which can ensure the synchronous rotation of the replacement member 8 with the adjusting wheel 3 and the wire feeding wheel 4. Moreover, during the use process, the replacement member 8 will be gradually worn. The adjusting wheel 3 and the wire feeding wheel 4 do not contact the welding wire 14 and are not easily worn. After a certain degree of wear in the later stage, it is not necessary to replace the whole adjusting wheel 3 and the wire feeding wheel 4, and only the replacement member 8 needs to be replaced, which can reduce resource waste. And the rotating limiting bar 11 makes the mounting threaded rod 12 disengage from the threaded hole 10, and the replacement member 8 is moved outwards to make it disengage from the adjusting wheel 3 and the wire feeding wheel 4 to complete the disassembly. Reversing the above operations can complete the installation, which is relatively convenient.
