Description

Technical Field

[0001] This utility model belongs to the field of welding gun components for electric welding machines, and specifically relates to a welding gun component for electric welding machines. Background Technology

[0002] Existing welding torch assemblies for electric welding machines enable basic welding operations, providing operators with a handheld support structure. Some components allow for simple adjustment of the torch position to meet routine welding needs. Their stable structure facilitates quick and easy operation, adapts to most common welding scenarios, ensures basic welding quality, provides essential tool support for welding operations, and helps improve welding efficiency.

[0003] Existing technologies have specifically developed some, for example, Chinese patent with announcement number "CN220388206U" discloses "a welding gun structure for an electric welding machine", which is equipped with a round tube and a movable tube. During use, the round tube can be rotated according to actual needs, so that the movable tube extends to a suitable length from the round tube, thereby realizing the adjustment of the position of the welding gun head and further facilitating the welding operation.

[0004] Although the structure includes a circular tube and a movable tube, allowing the circular tube to rotate and extend to a suitable length to adjust the welding torch head position and facilitate welding, the simple sleeve or threaded connection between the movable tube and the circular tube makes it difficult to securely fix. This makes it prone to loosening due to welding vibrations. When the circular plate of the positioning mechanism is pulled out, the movable rod lacks stable guidance and is prone to shaking and displacement, causing the conical end to disengage from the slot. This affects the stability of the welding torch head's angle positioning and makes it difficult to meet the requirements of high-precision welding. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a welding gun assembly for an electric welding machine to solve the problems of welding gun assemblies for electric welding machines.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A welding torch assembly for an electric welding machine includes a circular tube. Multiple slots are formed inside the upper outer circumference of the circular tube. A movable tube is slidably installed inside the circular tube. A locking block is movably installed on one side of the upper end of the movable tube, engaging with the slots. Side plates are fixedly installed on both sides of one end of the movable tube. Rotating grooves are formed inside the side plates on both sides. Rotating rods are rotatably installed inside the rotating grooves. A welding torch head is fixedly installed between the two rotating rods. A buffer groove is formed inside the side plates on both sides away from the movable tube. A buffer column is movably installed inside the buffer groove. A positioning column is fixedly installed at one end of the buffer column. The positioning column is slidably installed inside the rotating rod. A pull plate is fixedly installed at the end of the buffer column away from the positioning column.

[0008] As a preferred technical solution, the circular tube has a movable groove inside, and the movable tube is slidably installed inside the circular tube through the movable groove. A protective plate is integrally formed on one side of the circular tube.

[0009] As a preferred technical solution, a slot is provided on one side of the inner ring of the movable tube, and a locking spring is fixedly installed inside the slot. The end of the locking spring away from the slot is fixedly installed at the bottom of the locking block, and the locking block is movably installed inside the movable tube through the spring and the slot.

[0010] As a preferred technical solution, a baffle is fixedly installed at the end of the rotating rod on both sides away from the welding gun head, and multiple positioning grooves are opened inside the outer ring of the rotating rod on both sides.

[0011] As a preferred technical solution, the buffer groove has a connecting groove inside, which is connected to the rotating groove, and multiple limiting grooves are provided inside the outer ring of the buffer groove at the end of the side plate away from the movable tube on both sides.

[0012] As a preferred technical solution, a buffer spring is fixedly installed inside the buffer groove, and the end of the buffer spring away from the buffer groove is fixedly installed on one side of the pull plate.

[0024] Example

[0025] refer to Figures 1-6 This embodiment of a welding torch assembly for an electric welding machine includes a circular tube 3. Multiple slots 1 are formed inside the upper outer circumference of the circular tube 3. A movable tube 6 is slidably installed inside the circular tube 3. A locking block 2 is movably installed on one side of the upper end of the movable tube 6, engaging with the slots 1. Side plates 7 are fixedly installed on both sides of one end of the movable tube 6. Rotating grooves 10 are formed inside the side plates 7. Rotating rods 13 are rotatably installed inside the rotating grooves 10. A welding torch head 5 is fixedly installed between the two rotating rods 13. A buffer groove 15 is formed inside the side plates 7 at the end furthest from the movable tube 6. A buffer column 19 is movably installed inside the buffer groove 15. A positioning column 17 is fixedly installed at one end of the buffer column 19, slidably installed inside the rotating rod 13. A pull plate 11 is fixedly installed at the end of the buffer column 19 furthest from the positioning column 17.

[0026] refer to Figures 1 to 5The round tube 3 has a movable groove 8 inside, and the movable tube 6 is slidably installed inside the round tube 3 through the movable groove 8. A protective plate 4 is integrally formed on one side of the round tube 3. The protective plate 4 on one side of the round tube 3 is integrally formed with the round tube 3 and can block the welding slag during welding and protect the operator's hands.

[0027] refer to Figure 1 , Figures 5 to 6 A slot 22 is provided on one side of the outer ring of the movable tube 6. A locking spring 21 is fixedly installed inside the slot 22. The end of the locking spring 21 away from the slot 22 is fixedly installed at the bottom of the locking block 2. The locking block 2 is movably installed inside the movable tube 6 through the spring and the slot 22. When the length needs to be adjusted, press the locking block 2 to compress the locking spring 21 and make it disengage from the slot 1. At this time, the movable tube 6 can be pushed to slide along the movable groove 8 to the target position. After releasing the locking block 2, the locking spring 21 resets and pushes the locking block 2 to re-engage into the corresponding slot 1, thus completing the length fixation.

[0028] refer to Figure 2 , Figures 3 to 4Both ends of the rotating rods 13 away from the welding gun head 5 are fixedly equipped with baffles 9. Multiple positioning grooves 12 are formed inside the outer ring of both rotating rods 13. A connecting groove 16 is formed inside the buffer groove 15, which is connected to the rotating groove 10. Multiple limiting grooves 14 are formed inside the side plates 7 at the ends away from the movable tube 6, located on the outer ring of the buffer groove 15. A buffer spring 18 is fixedly installed inside the buffer groove 15. The end of the buffer spring 18 away from the buffer groove 15 is fixedly installed on one side of the pulling plate 11. Positioning pins... 17 is slidably installed inside the positioning groove 12 via the connecting groove 16. Multiple limiting rods 20 are fixedly installed on one side of the pull plate 11 near the buffer spring 18, on the outer ring of the buffer spring 18. The limiting rods 20 are slidably installed inside the limiting groove 14. The rotating rod 13 is rotatably connected to the side plate 7 via the rotating groove 10. The welding torch head 5 fixed between two rotating rods 13 can rotate synchronously with the rotating rod 13 to adjust the welding angle. The multiple positioning grooves 12 on the outer ring of the rotating rod 13 and the positioning posts 17 in the buffer groove 15... In conjunction, an angle positioning structure is formed. When adjusting the angle, pulling the pull plate 11 outward causes the buffer column 19 to slide along the buffer groove 15, compressing the buffer spring 18. Simultaneously, the positioning column 17 disengages from the positioning groove 12 along with the buffer column 19, releasing the lock on the rotating rod 13. At this point, after rotating the welding torch head 5 to the target angle, the pull plate 11 is released, the buffer spring 18 resets, and pushes the buffer column 19 back. The positioning column 17 passes through the connecting groove 16 and re-engages into the corresponding positioning groove 12, completing the angle fixation. To avoid pulling the plate during angle adjustment... When the pull plate 11 is shaken, multiple limiting rods 20 on the side of the pull plate 11 near the buffer spring 18 are embedded in the limiting groove 14 of the side plate 7 to form a guiding constraint. When the pull plate 11 moves, the limiting rods 20 slide along the limiting groove 14 to ensure that the buffer post 19 and the positioning post 17 always move in a straight line, avoiding the positioning post 17 from shifting and failing to accurately engage with the positioning groove 12. In addition, a baffle 9 is fixed at the end of the rotating rod 13 away from the welding gun head 5 to prevent the rotating rod 13 from rotating excessively and disengaging from the rotating groove 10, further improving the structural stability.

[0029] Operating principle and advantages: During use, the internal movable groove 8 provides a sliding track for the movable tube 6, allowing the movable tube 6 to freely extend and retract along the inner cavity of the circular tube 3, thereby changing the overall length of the welding torch. A locking spring 21 is installed inside the groove 22 at the upper end of the movable tube 6. The locking spring 21 pushes the locking block 2 upwards, causing the locking block 2 to engage in the locking groove 1 at the upper end of the outer ring of the circular tube 3, forming a positioning lock. When length adjustment is required, pressing the locking block 2 compresses the locking spring 21, causing it to disengage from the locking groove 1. At this time, the movable tube 6 can be pushed along the movable groove 8 to the target position. After the locking block 2 is released, the locking spring 21 resets and pushes the locking block 2 back into the corresponding slot 1, completing the length fixation. The protective plate 4 on one side of the round tube 3 is integrally formed with the round tube 3, which can block the welding slag during welding and protect the operator's hands. The two side plates 7 at the extension end of the movable tube 6 are provided with rotating grooves 10. The rotating rod 13 is rotatably connected to the side plate 7 through the rotating groove 10. The welding gun head 5 fixed between the two rotating rods 13 can rotate synchronously with the rotating rods 13 to realize the adjustment of the welding angle. Multiple positioning grooves 12 are opened on the outer ring of the rotating rod 13. The positioning post 17, in conjunction with the positioning post 17 within the buffer groove 15, forms an angle positioning structure. When adjusting the angle, pulling the pull plate 11 outward causes the buffer post 19 to slide along the buffer groove 15, compressing the buffer spring 18. Simultaneously, the positioning post 17, along with the buffer post 19, disengages from the positioning groove 12, releasing the lock on the rotating rod 13. At this point, after rotating the welding torch head 5 to the target angle, the pull plate 11 is released, the buffer spring 18 resets, pushing the buffer post 19 back. The positioning post 17 passes through the connecting groove 16 and re-engages into the corresponding positioning groove 12, completing the angle fixation. To avoid angle... During adjustment, the pull plate 11 shakes, and multiple limiting rods 20 on the side of the pull plate 11 near the buffer spring 18 are embedded in the limiting groove 14 of the side plate 7 to form a guiding constraint. When the pull plate 11 moves, the limiting rods 20 slide along the limiting groove 14 to ensure that the buffer post 19 and the positioning post 17 always move in a straight line, avoiding the positioning post 17 from shifting and failing to accurately engage with the positioning groove 12. In addition, a baffle 9 is fixed at the end of the rotating rod 13 away from the welding gun head 5 to prevent the rotating rod 13 from rotating excessively and disengaging from the rotating groove 10, further improving the structural stability.
