Description

Technical Field

[0001] This utility model relates to the field of wire feeding technology, specifically a laser welding wire feeding machine. Background Technology

[0002] Laser welding is a highly efficient and precise welding method that uses a high-energy-density laser beam as a heat source. Laser welding is mainly divided into filler wire welding and non-filler wire welding. Filler wire welding can pre-fill specific welding materials into the weld and then melt them with laser irradiation or fill the welding materials at the same time as laser irradiation to form a weld joint. Compared with non-filler wire welding, it has advantages such as solving the problem of strict requirements for workpiece processing and assembly, achieving welding of thicker and larger parts with lower power, and controlling the microstructure and properties of the weld area by adjusting the filler wire composition.

[0003] Laser welding mainly involves feeding welding wire to the welding area of ​​the workpiece using a wire feeder. However, the wire feeders currently in use can only transport a single welding wire and cannot adjust for multiple welding wires, resulting in low transport efficiency. Furthermore, the wire pressing wheel structure used to tighten the welding wire is fixed and cannot be adjusted according to the thickness of the welding wire. Therefore, we propose a laser welding wire feeder. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a laser welding wire feeder includes a mounting housing, inside which a second electric telescopic rod is fixedly mounted, and at the output end of the second electric telescopic rod is a first mounting frame fixedly mounted. A fourth rotating shaft is rotatably connected inside the first mounting frame, and a first wire pressing wheel is fixedly sleeved on the outer side of the fourth rotating shaft. A side plate is fixedly mounted inside the mounting housing, and a sliding groove is formed on one side of the side plate. A slider is slidably connected inside the sliding groove, and a second mounting frame is fixedly mounted on one side of the slider. A third rotating shaft is rotatably connected inside the second mounting frame, and a second wire pressing wheel is fixedly sleeved on the outer side of the third rotating shaft.

[0006] Preferably, a motor is fixedly mounted on one side of the second mounting bracket, the output end of the motor is fixedly connected to a first rotating shaft, a second rotating shaft is rotatably connected to one side of the second mounting bracket, and one end of the second rotating shaft is fixedly connected to one end of a third rotating shaft.

[0007] Preferably, a first pulley is fixedly sleeved on the outer side of both the second rotating shaft and the first rotating shaft, and the first pulley is connected by belt drive.

[0008] Preferably, two first electric telescopic rods are fixedly installed on the outer side of the mounting housing, a mounting plate is fixedly installed on one side of the first electric telescopic rod, a connecting plate is fixedly installed on one side of the mounting plate, and the second mounting bracket is fixedly connected to the connecting plate.

[0010] Preferably, support legs are fixedly installed on both sides of the mounting housing.

[0011] This utility model provides a laser welding wire feeder, which has the following beneficial effects:

[0012] This laser welding wire feeder uses a first electric telescopic rod to move a mounting plate, which in turn moves a connecting plate. The position of the second mounting frame can be adjusted by moving the connecting plate, and the slider slides within the groove. The distance between the wires can be adjusted by moving the second mounting frame. A motor drives a first rotating shaft, which in turn rotates an outer first pulley. This pulley, in turn, rotates a third rotating shaft on one side, which in turn rotates a second wire-pressing wheel. This completes the wire feeding process. When multiple wires need to be fed, the second electric telescopic rod moves the first mounting frame, adjusting it to the bottom of the second mounting frame, allowing for the feeding of two wires at a time. This adjusts the number of wires fed, improving practicality. Attached Figure Description

The output end of the motor 17 is fixedly connected to the first rotating shaft 15. A second rotating shaft 16 is rotatably connected to one side of the second mounting bracket 10. One end of the second rotating shaft 16 is fixedly connected to one end of the third rotating shaft 18. A first pulley 14 is fixedly sleeved on the outer side of both the second rotating shaft 16 and the first rotating shaft 15. The first pulley 14 is connected by belt drive. Two first electric telescopic rods 11 are fixedly mounted on the outer side of the mounting housing 1. A mounting plate 12 is fixedly mounted on one side of the first electric telescopic rod 11. A connecting plate 13 is fixedly installed on one side of the mounting housing 1. The second mounting bracket 10 is fixedly connected to the connecting plate 13. A second wire feeding port 6 is opened on the outer side of the mounting housing 1, and a first wire feeding port 5 is opened on the outer side of the mounting housing 1. Support legs 4 are fixedly installed on both sides of the mounting housing 1. By using the first electric telescopic rod 11 to drive the mounting plate 12 to move, the connecting plate 13 can be moved. By using the connecting plate 13 to move, the position of the second mounting bracket 10 can be adjusted. At the same time, the slider 8 is moved inside the slide groove 7. By using the second mounting bracket 10 to move, the spacing between the pressing wires can be adjusted. By using the motor 17 to drive the first rotating... The shaft 15 rotates, which drives the outer first pulley 14 to rotate. The rotation of the first pulley 14 drives the third shaft 18 on one side to rotate, which in turn drives the second pressure roller 19 to rotate, thus completing the wire feeding operation. When multiple wires need to be fed, the first mounting frame 2 can be moved by the second electric telescopic rod 20, which can adjust the first mounting frame 2 to the bottom of the second mounting frame 10, and adjust their spacing to allow two wires to be fed. This improves practicality by adjusting the number of wires fed.

Moving the connecting plate 13 adjusts the position of the second mounting frame 10 and simultaneously causes the slider 8 to slide within the groove 7. Moving the second mounting frame 10 adjusts the spacing between the pressure wires. After adjustment, the motor 17 drives the first rotating shaft 15 to rotate, which in turn rotates the outer first pulley 14. The rotation of the first pulley 14 then drives the third rotating shaft 18 on one side to rotate, which in turn rotates the second pressure roller 19. This completes the wire feeding operation. When multiple wires need to be fed, the second electric telescopic rod 20 moves the first mounting frame 2, adjusting it to the bottom of the second mounting frame 10 and setting the spacing between them to allow for the feeding of two wires, thus completing the feeding operation.
