[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0021] Reference Figures 1 to 3 The utility model provides an embodiment: an adjustable laser wire feeding head, including a fixed bracket 1, which serves as the basic support structure of the entire laser wire feeding head device. A height adjustment locking block 4 is fixedly connected to the right side of the fixed bracket 1, and an adjustment component for adjusting the height is provided on the top of the height adjustment locking block 4. The adjustment component includes an adjustment block 5, and the bottom of the adjustment block 5 is provided on the top of the height adjustment locking block 4. The top of the height adjustment locking block 4 is threadedly connected with two adjustment bolts 7. When adjusting the height, the user can rotate the adjustment bolt 7 to move the adjustment block 5 up and down on the height adjustment locking block 4, thereby driving the wire feeding head assembly to achieve a change in height. A spacer ring 3 is fixedly connected to the rear side of the height adjustment locking block 4. The spacer ring 3 is a component installed on the rear side of the height adjustment locking block 4, and its main function is to isolate and protect other structures. An angle adjustment rod 2 is provided on the front side of the height adjustment locking block 4. The external thread of the angle adjustment rod 2 is connected to a nut 8. The front side of the height adjustment locking block 4 is threadedly connected to two adjusting bolts 9. When adjusting the angle, the user can rotate the nut 8 to move the angle adjustment rod 2 back and forth on the height adjustment locking block 4, thereby driving the wire feeding head assembly to achieve angle changes.
[0022] Reference Figure 2 and Figure 3The bottom of the height adjustment locking block 4 is equipped with an adjustment shaft 10. A connecting block 19 is located on the outer underside of the adjustment shaft 10. The adjustment shaft 10 is fixedly connected to the connecting block 19 via clamping bolts 6. Multiple clamping bolts 6 are threaded onto the front of the connecting block 19. The user can rotate the clamping bolts 6 to tightly fit the connecting block 19 against the adjustment shaft 10 and the heat shield 13, thereby achieving a fixed connection. A heat shield 13 is fixedly connected to the right side of the connecting block 19. This component is installed on the right side of the connecting block 19 and its primary function is to isolate the high temperatures generated during welding and protect the internal mechanical structure of the device from damage. A docking block 20 is fixedly connected to the top of the heat shield 13. A quick connector 15 is fixedly connected to the right side of the docking block 20. This connector facilitates installation and maintenance of the device. A cooling water inlet 16 is fixedly connected to the top of the docking block 20. This inlet provides cooling water to the weld, reducing temperatures during welding and protecting the wire feeder and workpiece from damage. The cooling water inlet 16 is removably connected to a water source for providing cooling water. The top of the docking block 20 is fixedly connected to a wire feed guide 14. The wire feed guide 14 provides the wire to the wire feed head, enabling wire transportation during the welding process. The bottom of the connecting block 19 is provided with a wire feed head assembly for feeding the wire. The wire feed head assembly includes a gun head clamp 11. The top of the gun head clamp 11 is fixedly connected to the bottom of the connecting block 19. The bottom of the gun head clamp 11 is fixedly connected to the gun rod 12. The gun head clamp 11 is used to fix the gun rod 12 and the wire outlet gun head 17, ensuring the stability and reliability of the wire feed head. The bottom of the gun rod 12 is provided with a wire outlet gun head 17. The wire outlet gun head 17 is used to melt the welding wire and spray it onto the workpiece, enabling the welding operation during the welding process. The external threaded connection of the wire outlet gun head 17 is connected to a locking nut 18. The locking nut 18 is used to fix the wire outlet gun head 17, ensuring the stability and reliability of the wire feed head.
[0023] Working principle: The right side of the fixed bracket 1 of the wire feeder is connected to the adjustment assembly through the height adjustment locking block 4, allowing the user to adjust the height of the wire feeder as needed. The bottom of the adjustment block 5 in the adjustment assembly is set on the top of the height adjustment locking block 4, and is threadedly connected through two adjustment bolts 7, thereby ensuring the stability and accuracy of the height adjustment. With the combined use of the angle adjustment rod 2 and the nut 8, the wire feeder can be finely adjusted at an angle, further enhancing its adaptability. The front side of the height adjustment locking block 4 is connected to the adjustment shaft 10 through two adjustment bolts 9, and the connecting block 19 on the outer bottom side of the adjustment shaft 10 is fixedly connected to the heat insulation plate 13 through the clamping bolt 6. This design not only ensures stable adjustment of the wire feeder in the vertical direction, but also facilitates fine adjustment in the horizontal direction. The setting of the heat insulation plate 13 effectively isolates the high temperature generated during the welding process and protects the internal mechanical structure from damage. The wire feeder assembly is the core of the device. The gun head clamp 11 is fixed to the bottom of the connecting block 19, and the gun rod 12 extends from the gun head clamp 11 to the wire feeder head 17, which is fixed by a locking nut 18. This design allows the wire feeder to maintain stability while also having good operational flexibility. In addition, the design of the docking block 20 allows the cooling water inlet 16 and the wire feed guide tube 14 to be integrated into the wire feeder, which not only simplifies the layout of the external pipeline, but also improves the cooling efficiency and the stability of the wire feeding. The use of the quick connector 15 further facilitates the installation and maintenance of the equipment.
