With the continuous development of industrial manufacturing, the requirements for welding accuracy, efficiency and flexibility are increasing. In many complex welding scenarios, traditional welding guns are difficult to meet the needs. Most existing welding guns are inconvenient to disassemble and carry, and the adjustment of the welding wire position is not easy to achieve. The operational flexibility is poor, which leads to certain disadvantages in use.

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.

[0034] Reference Figure 1 - Figure 3 The adjusting assembly includes a rotating shaft 61, the outer wall of which is fixedly connected to a connecting plate 62. The rotating shaft 61 is located at a right position on the front surface of the connecting plate 62, and the connecting plate 62 will rotate around the center of the rotating shaft 61. The left surface of the connecting plate 62 is provided with a fixing assembly, which can clamp and fix the barrel 3. The front surface of the rotating shaft 61 passes through and is slidably connected to a slide bar 64, which slides in the front and rear directions. The front surface of the slide bar 64 is fixedly connected to a button 63. Pressing the button 63 can drive the slide bar 64 to move backward. The adjusting assembly also includes a disc 67, the front surface of the disc 67 is fixedly connected to a block 68, and the rear surface of the fixed block 5 is provided with a slot 601. The block 68 and the slot 601 fit together. The block 68 and the slot 601 are both provided with multiple groups, which are arranged in a circular array with the center of the disc 67 as the origin. The inner wall of the rotating shaft 61 is elastically connected to a round block 65 through a compression spring 66.

[0035] Reference Figure 1 、 Figure 3 、 Figure 4The locking cam 76 is fixed on the top of the locking cam 77 so that the lock 71 can be locked.

[0036] Reference Figure 1 - Figure 3 The rotating shaft 61 passes through and is rotatably connected to the front surface of the fixed block 5. The rear end of the slide rod 64 passes through the rear surface of the rotating shaft 61. In the initial position, the rear end of the slide rod 64 is flush with the rotating shaft 61 and the rear end of the fixed block 5. The front surface of the disc 67 is fixedly connected to the rear surface of the slide rod 64. The slide rod 64, the disc 67 and the block 68 will move synchronously. The block 68 is inserted into the inner wall of the card slot 601. When the slide rod 64 and the disc 67 move backward, the block 68 will be separated from the card slot 601. The front end of the block 68 is set to an arc shape, even if the angle is small When there is deviation, it can also be plugged into the slot 601. The centers of the rotating shaft 61, button 63, slide bar 64, and disk 67 are located on the same horizontal line. The round block 65 is slidably connected to the inner wall of the rotating shaft 61 and moves in the front and back directions. The slide bar 64 passes through and is fixedly connected to the front surface of the round block 65. One end of the compression spring 66 is fixedly connected to the rear surface of the round block 65, and the other end of the compression spring 66 is fixedly connected to the inner wall of the rear side of the rotating shaft 61. When the slide bar 64 moves backward, it will drive the round block 65 to move backward and squeeze the compression spring 66 to generate a reaction force.

[0037] Reference Figure 1 、 Figure 3 、 Figure 4The top of the right surface of the positioning plate 71 is fixedly connected to the left surface of the connecting plate 62. The positioning plate 71 will swing synchronously with the swing of the connecting plate 62 around the rotating shaft 61. The threaded rod 72 passes through and is threadedly connected to the upper surface of the positioning block 73. When the threaded rod 72 rotates, it drives the positioning block 73 to move longitudinally. The front and rear ends of the lower surface of the positioning block 73 are set as inclined surfaces, and the front section of the upper surface of the moving block 74 is set as an inclined surface. The inclined surface of the positioning block 73 and the inclined surface of the moving block 74 are in contact with each other. The t-shaped block 77 is slidably connected to the inner wall of the T-shaped groove 701. When the T-shaped groove 701 moves, it will squeeze the T-shaped block 77 and drive the T-shaped block 77 to move. The clamping block 76 is set to an arc shape. The moving block 74, the connecting block 75, the clamping block 76, and the T-shaped block 77 are provided in two groups, which are symmetrically distributed with respect to the center line of the positioning plate 71. The front surface of the clamping block 76 is provided with a gun barrel 3. The two groups of clamping blocks 76 can clamp and fix gun barrels 3 of different models. The left surface of the gun barrel 3 is provided with a connecting line 4.

[0038] Working principle: When in use, the operator holds the welding gun by the handle 9 and presses the switch to start the welding operation.

[0039] When the angle of the gun barrel 3 needs to be adjusted, the button 63 is pressed, causing the slide bar 64 to move backward. The slide bar 64 then drives the disc 67 and the block 68 backward, causing the block 68 to disengage from the slot 601. At this point, the connecting plate 62 can be rotated around the center of the rotating shaft 61, thereby driving the fixing assembly and the gun barrel 3 to change angles. After adjusting to the appropriate angle, the button 63 is released. Under the reaction force of the compression spring 66, the slide bar 64 moves forward, pushing the disc 67 and the block 68 forward. The block 68 is reinserted into the corresponding slot 601, thus fixing the angle.

[0040] When fixing the gun barrel 3, the hand wheel is rotated to drive the threaded rod 72 to rotate. The rotation of the threaded rod 72 causes the positioning block 73 to move upward. When the positioning block 73 moves upward, it drives the T-slot 701 to move upward. When the T-slot 701 moves, it squeezes the T-block 77, further driving the two groups of T-blocks 77, the movable block 74, the connecting block 75 and the clamping block 76 to contract, thereby clamping and fixing gun barrels 3 of different models. If it is necessary to release the clamping, when disassembling the gun barrel 3, the hand wheel is rotated in the opposite direction to drive the threaded rod 72 to rotate in the opposite direction. When the threaded rod 72 rotates in the opposite direction, the positioning block 73 moves downward, further driving the two groups of T-blocks 77, the movable block 74, the connecting block 75 and the clamping block 76 to open and release the clamping of the gun barrel 3, and then the gun barrel 3 can be disassembled.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
