[0019] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0020] like Figure 1-Figure 4 As shown, the utility model provides a technical solution:

[0021] A welding gun wire feeding mechanism, comprising a rotating ring 1, a gear ring 2 coaxially fixedly connected to one side of the rotating ring 1, a connecting block 3 fixedly connected to the bottom of the rotating ring 1, a rotating rod 1 4 rotatably connected to the connecting block 3, a rotating rod 1 4 rotatably connected to one end of the rotating rod 1 5, and a wire feeding tube 6 fixedly connected to one end of the rotating rod 2 5;

[0022] Specifically, the rotating rod 1 4 can rotate on the connecting block 3, and the rotating rod 2 5 can drive the wire feeding tube 6 to rotate with the rotating connection between the rotating rod 2 5 and the rotating rod 1 4 as the center. By rotating and adjusting the rotating rod 1 4 and the rotating rod 2 5, the position of the wire feeding tube 6 and the wire feeding angle can be changed;

[0023] A welding gun, comprising a welding gun body 7 and a welding gun wire feeding mechanism, wherein a cylindrical block 8 is fixedly connected to one side of the welding gun body 7, the welding gun wire feeding mechanism is arranged on the cylindrical block 8, a fixing assembly is arranged on the welding gun body 7, a nozzle 9 is arranged on one side of the cylindrical block 8, and a handle 10 is arranged at the bottom of the welding gun body 7;

[0024] Specifically, the rotating ring 1 can rotate on the cylindrical block 8, so that the wire feeding mechanism of the welding gun can rotate around the nozzle 9 under the drive of the rotating ring 1, which greatly improves the flexibility of the welding operation and can adapt to the welding requirements of various complex angles. It also reduces the possibility of interference between the wire feeding mechanism and surrounding objects, improves work efficiency, and provides a strong guarantee for high-quality welding operations.

[0025] The fixing assembly includes a sliding rod 11, which is slidably connected to the welding gun body 7. A movable groove is provided on one side of the welding gun body 7. One end of the sliding rod 11 is fixedly connected to a slider 12. The side of the slider 12 away from the sliding rod 11 is fixedly connected to a limit rod 13. A spring 14 is sleeved on the outer periphery of the limit rod 13. The side of the slider 12 away from the sliding rod 11 is rotatably connected to a connecting shaft 15. One end of the connecting shaft 15 is coaxially fixedly connected to a handle 16.

[0026] Specifically, the handle 16 can be used to drive the slider 12 to move, so that the sliding rod 11 and the limiting rod 13 move together with the slider 12. A movable hole corresponding to the limiting rod 13 is opened on the inner wall of the movable groove. The limiting rod 13 can move in the movable hole, and the spring 14 is compressed.

[0027] The end of the sliding rod 11 away from the slider 12 is fixedly connected with a clamping block 17;

[0028] Specifically, the sliding rod 11 drives the clamping block 17 away from the gear ring 2, so that the gear ring 2 is released;

[0029] The bottom of the slider 12 is slidably connected to the movable groove;

[0030] Specifically, the slider 12 slides on the movable groove;

[0031] A receiving slot is provided on one side of the welding gun body 7, and a pair of card slots are provided on the receiving slot, and the handle 16 is adapted to the card slots;

[0032] Specifically, the handle 16 is rotated so that the handle 16 is away from the slot.

[0033] The working principle of this utility model is:

[0034] First, turn the handle 16 to move it away from the slot, then push the handle 16, and the slider 12 can be driven to slide on the movable slot through the connecting shaft 15, so that the sliding rod 11 and the limiting rod 13 move together with the slider 12. A movable hole corresponding to the limiting rod 13 is opened on the inner wall of the movable slot, and the limiting rod 13 can move in the movable hole. The spring 14 is compressed, and the sliding rod 11 drives the clamping block 17 away from the gear ring 2, so that the gear ring 2 is released. Then, turn the handle 16 so that the handle 16 falls into another slot away from the cylindrical block 8;

[0035] The rotating ring 1 can then be rotated so that the wire feeding mechanism of the welding gun can be driven to rotate around the nozzle 9. This greatly improves the flexibility of the welding operation and can adapt to welding requirements of various complex angles. It also reduces the possibility of interference between the wire feeding mechanism and surrounding objects, improves work efficiency, and provides a strong guarantee for high-quality welding operations.

[0036] When the wire feeding mechanism of the welding gun is rotated to the appropriate position, the handle 16 is rotated again to make the handle 16 move away from the slot, and the spring 14 pushes the slider 12 to slide close to the cylindrical block 8, so that the sliding rod 11 drives the block 17 to clamp the gear ring 2, and then the handle 16 is rotated to make the handle 16 fall into the slot close to the cylindrical block 8. At this time, the spring 14 has a certain deformation, so that the slider 12 cannot slide arbitrarily, which can effectively prevent the wire feeding mechanism from accidentally loosening or rotating during work, enhances the stability of wire feeding, and reduces the risk of injury to the operator. When it is necessary to rotate and adjust the wire feeding position, it can be quickly fixed through the fixing component, which facilitates switching between different welding scenes and improves work efficiency.

[0037] The above describes in detail the preferred embodiments of this patent, but this patent is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in this field without departing from the purpose of this patent.
