[0001] The utility model relates to the technical field of push-pull wire welding guns, in particular to a portable push-pull wire welding gun. Background Art

[0002] In the field of industrial production, welding processes play a vital role. As a key component of welding equipment, the performance and ease of use of push-pull wire welding guns directly affect the efficiency and quality of welding work. With the continuous development of the manufacturing industry, the requirements for welding processes are increasing. Not only do we pursue higher welding accuracy and speed, but we also focus on the operator's comfort and work efficiency when using the welding gun.

[0003] Although existing push-pull welding guns are lightweight, they often require workers to hold the gun with one hand during welding. This prolonged single-handed operation places constant strain on the hand muscles, leading to hand fatigue and compromising welding stability and accuracy. This can reduce welding quality, leading to uneven welds and insufficient weld strength, while also reducing work efficiency and increasing workload and labor costs. Utility Model Content

DETAILED DESCRIPTION

[0015] 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.

[0016] Example: Figure 1-3As shown, the utility model provides a portable push-pull welding gun, including a push-pull welding gun wire feeding part 1, a fixing mechanism 11 is provided at the bottom edge of the push-pull welding gun wire feeding part 1, the fixing mechanism 11 includes a connecting plate 12, a fixing block 13, a double-headed screw 14 with opposite threads at both ends, two clamping plates 15, a limiting rod 16, two limiting disks 17, and a rotating wheel 18. The bottom end of the connecting plate 12 is fixedly installed with two symmetrically distributed fixing seats 2, and the bottom of the fixing seat 2 is rotated through by a rotating shaft 21 A connecting column 22 is fixedly installed on the outside of the rotating shaft 21, and the connecting column 22 is located between the two fixed seats 2. A cylinder 23 is fixedly installed on the bottom end of the connecting column 22, and a shell 24 is fixedly installed on the lower surface of the connecting plate 12. A worm 25 is rotatably installed on the bottom of the shell 24. The worm 25 is located inside the shell 24, and a worm wheel 26 is meshed and connected to the outside of the worm 25. The worm wheel 26 is fixedly connected to the rotating shaft 21, and the rotating shaft 21 rotates through the shell 24. A handle 3 is fixedly installed on one end of the worm 25.

[0017] The fixed block 13 is fixedly connected to the connecting plate 12 , and the fixed block 13 is located in the middle position of the connecting plate 12 . The double-headed screw 14 rotates through the fixed block 13 . The two clamping plates 15 are threadedly connected to the double-headed screw 14 , and the rotating wheel 18 is fixedly connected to one end of the double-headed screw 14 .

[0018] The limiting rod 16 is fixedly connected to the fixed block 13. The limiting rod 16 is located at the top of the fixed block 13. The two clamps 15 are slidably sleeved on the outside of the limiting rod 16. By setting the limiting rod 16, the clamps 15 are limited to prevent the clamps 15 from rotating as the double-headed screw 14 rotates, affecting the clamps 15 from fitting with the wire feeding part 1 of the push-pull welding gun and being fixed together with the wire feeding part 1 of the push-pull welding gun.

[0019] The two limit plates 17 are fixedly connected to the limit rod 16, and the limit plates 17 are respectively fixed at both ends of the limit rod 16. The diameter of the limit plates 17 is larger than the diameter of the limit rod 16. By setting the limit plates 17, when the splint 15 moves to both sides with the rotation of the double-headed screw 14, and then under the action of the limit plates 17, the splint 15 is prevented from separating from the limit rod 16, thereby affecting the next movement of the splint 15 to the middle and being fixed to the wire feeding part 1 of the push-pull welding gun.

[0020] Several annular and evenly distributed anti-slip strips 19 are fixedly installed on the outside of the rotating wheel 18. By providing the anti-slip strips 19, the friction between the hand and the rotating wheel 18 is increased, making it easier to rotate the rotating wheel 18 and drive the double-headed screw 14 to rotate.

[0021] The length of the limiting rod 16 should be shorter than the length of the double-headed screw 14, and the length of the double-headed screw 14 should be longer than the length of the connecting plate 12 to avoid the limiting plate 17 and the connecting plate 12 blocking the rotation of the rotating wheel 18 when the rotating wheel 18 is rotated, thereby affecting the rotation of the double-headed screw 14 driven by the rotating wheel 18.

[0022] The handle 3 is in the shape of a plum blossom, which makes it easier to apply force when the plum blossom-shaped handle 3 is rotated, and makes it more convenient for the staff to rotate the handle 3 and drive the worm 25 to rotate.

[0023] A rubber sleeve 4 is fixedly installed on the outside of the cylinder 23, and several groups of annular and evenly distributed anti-slip particles are fixedly installed on the outside of the rubber sleeve 4. By setting the rubber sleeve 4 and the anti-slip particles, the friction between the handle 3 and the hand is increased. Even if the hand is sweaty or oily, it can ensure that the handle 3 will not slip out of the hand, further improving the safety and comfort of operation.

[0024] Working principle: In actual use, when the staff uses the push-pull welding gun, they hold the push-pull welding gun with one hand and hold the rubber sleeve 4 on the outside of the cylinder 23 with the other hand. When connecting the cylinder 23 with the wire feeding part 1 of the push-pull welding gun, first fix the connecting plate 12 and the wire feeding part 1 of the push-pull welding gun together through the fixing mechanism 11. The installation position can be selected according to actual conditions. After installation, adjust the angle of the cylinder 23 and the connecting column 22 according to the personal comfort when holding it. When adjusting the angle, turn the handle 3 to drive the worm 25 to rotate, and the engagement between the worm 25 and the worm wheel 26 drives the rotating shaft 21 to rotate. The rotation of the rotating shaft 21 drives the connecting column 22 and the cylinder 23 to rotate, thereby realizing the angle adjustment of the cylinder 23 and the connecting column 22;

[0025] The specific operation of the fixing mechanism 11 is to fit the top surface of the fixing block 13 with the bottom surface of the wire feeding part 1 of the push-pull wire welding gun, and then rotate the wheel 18 to drive the double-headed screw 14 to rotate. The clamping plate 15 is limited by the limiting rod 16, so that the rotation of the double-headed screw 14 drives the two clamping plates 15 to move toward the middle, so that the clamping plates 15 are fitted with both sides of the wire feeding part 1 of the push-pull wire welding gun, thereby fixing the connecting plate 12 on the wire feeding part 1 of the push-pull wire welding gun.

[0026] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
